• How the color in the Java object?

  My code:
  < cfset var image = createObject ("java", "java.awt.image.BufferedImage") / >
  < cfset var color = createObject ("java", "java.awt.Color") / >
  < cfset g = image.getGraphics () / >
  < cfset g.setColor (color.white) / >
  
  In the last line, I want to repalce the "color.white' with #F23ABB, how?
  Thank you.

  Try the decode() method and you must initialize the BufferedImage object before using it.

  The Java Exception: java.lang.reflect.InvocationTargetException: during the java.lang.reflect.Method .invoke call.

  I came across the same thing as you. I did a lot of experimenting and found it works:

  var result = (function() {
      var ReflectiveArray = java.lang.reflect.Array;
      var CreateSQL = Packages.PeopleSoft.PeopleCode.Func.CreateSQL;

      while (SQL.Fetch(columns)) {

      }
  
      return results.join();
  
  }());
  

  He seems to have been a problem with translation between the JavaScript array and the Java array Object []. I solved this by using java.lang.reflect.Array.newInstance to create a new instance of the object [1].

  Next issue to deal with is your memory problem. In the error message, it seems to have something to do with the Garbage Collection and a lot of temporary objects. You declare you line and cell by using the var =... line and cell var =...? If not, then they are in the global namespace and properties of the global object. At the end of each iteration of the loop, use delete line and delete cells. If you declare the var, then set their value null at the end of each iteration. Based on your code, I expect each time through the loop would decrease the number of references, but I saw where setting explicitly using null. The only other temporary object I see is the value in the table. Just for fun, I added this at the end of each loop, and he ran very well:

  columns[0] = null;
  

• How to get the XML from the Request of Java object before sending. SOAP Web services

  I'm building Java request to Online Web Services and we'll call it application A . I got the WSDL forms the second part of the file in order to communicate with their application and we'll call it application B .

  Of the WSDL file generate the Java required classes that are Requests and Responses . classes Application A will send some request object after setting the parameters required and with the exception of response object of application B .

  The connection is established and the two applications A and B communicate with each other.

  Question:

  Of application A How can I get the xml data (or text file) for the request object before sending it to application B ?

  As described the connection is passing Java object such as request and I know that in some point this request will be converted to xml file. How to get it?

  -EDIT-

  Missing important information which can be confusing.

  I'm generated the Java rating were generated using the Axis framework

  The problem is solved by, add the following statements in the bindingStub class that was automatically generated from the WSDL file to the web-services you are trying to access.

     String request = _call.getMessageContext().getRequestMessage().getSOAPPartAsString(); 
   String response = _call.getMessageContext().getResponseMessage().getSOAPPartAsString();
  

  These statements should be placed after the following method call _call.invoke otherwise you will get NullPointerException .

  _callis a variable of type org.apache.axis.client.Cal and it is automatically generated byAxis

• Distance communication: sending the custom Java objects

  Hello...
  I use Flex 3.01 - BlazedDS
  
  I have a few working methods implemented on the server I have retrieve custom objects and custom objects table... everything works perfectly...
  I also have a method that I pass a custom Flex object (mapped to a Java object) to retrieve another object Java (mapped to a Flex object) works perfectly...
  
  But I have this method I have send as an argument one of my items customized to retrieve another object custom... and when I invoke this method the cursor "occupied" remains as always and demand is slowing down...
  
  I checked the log on the server and I do not see the method called and no error...
  
  Trying to debug... I saw in the object AbstractOperation "1023 stack overflow" error getting caught, but when I run it normally I see no error...
  
  This object I send as an argument is like a custom class to hold one of my items for various operations on the server and the first method that works, the object I have send as and the argument is simple...
  
  This second purpose is as a container that contains a table of another container of objects containing any kind of my items...
  
  I thought that maybe there is a limit for mapping... I don't know... but I don't see any information to reach the server...
  
  If someone could help me, I would appreciate...
  
  Thank you
  

  Solved...

  It seems that by using the same RemoteObject to call a large number of methods on the same destination is not good...

  I created another RemoteObject to call the method and worked...

  Thanks anyway...

• How to expose java in javascript objects so that the javascript objects display method with &lt; ctrl &gt; signatures space in scripts

  Hi all

  I exponent of java objects in javascript, but the methods and attributes does not appear in the contextual help menu (< ctrl > + space) when I use these javascript objects.

  How should I write my vso.xml so that the javascript objects are aware of methods in the Help menu popup javascript.

  for example: -.

  entry VSO.xml:

  < enumerations >

  < list type = "TestEnum" >

  values of < description > defines attributes of objects managed Boolean xml < / description >

  < entries >

  < input id = "test1" name = "TEST1" > value to Test1. < / Entry >

  < input id = "test2" name = "TEST2" > value of Test2. < / Entry >

  < / input >

  < / enumeration >

  < / enumerations >

  < script objects >

  < script object 'MyObject' = java-class name = "com.test.MyObject" >

  < description > This is a test object < / description >

  <>attributes

  < attribute java-name = "attr1" return-type = "Chain" script-name = 'Attr1' show-in-api = "true" / >

  < attribute java-name = "attr1" return-type = "Chain" script-name = 'Attr1' show-in-api = "true" / >

  < / attribute >

  < / attribute >

  <>methods

  	< java-method name = "testMtd" return-type = "Chain" script-name = "testMtd" show-in-api = "true" >
  	< Parameters >
  	< name of the parameter = "param1" type = "Any" / >
  	< name of the parameter = "param2" type = "String" / >
  	< = 'param3' type parameter name = "boolean" / >
  	< / Parameter >
  	< / method >

  < / methods >

  < / object >

  < / scripting objects >

  JavaScript: -.

  var myObj = new MyObject();

  myObj. < ctrl > + space doesn't popup any context menu, as it does for string objects or object system.

  myObj.testMtd ("abc", TestEnum. < ctrl > + space - Enums are also not pop values.)

  Any help will be greatly appreciated.

  Best regards

  I see the use cases, and it would be wise to have seized semiautomatic for her, but as far as I KNOW is not possible right now.

  (I think it's comparable to the VcPlugin object. Useful methods Nice in there, but no AutoComplete)

• Should I return the JSON object or object java SOA?

  Hi gurus,

  A question that I hope makes sense - can SOA return a JSON object JAVA object, not XML?

  Thank you

  Anatoliy

  
  

  First "SOA" is not a thing, so it's difficult to give a Yes or no

  This is a technical product feature if it will be possible to expose data in xml/json/etc. formats

  When we look at the Oracle portfolio, we have a preview for example Oracle SOA Suite and Oracle Service Bus (other Oracle products can do the same thing).

  With these two products, you will be able to represent your data in other formats in addition to XML.

  some links to help you get started.

  https://blogs.Oracle.com/jeffdavies/entry/using_json_with_oracle_service

  http://Biemond.blogspot.nl/2010/05/HTTP-binding-in-SOA-Suite-11g-PS2.html

  http://javaoraclesoa.blogspot.nl/2012/12/receiving-JSON-requests-in-Oracle-BPEL.html

  Oracle Service Bus can also store Java objects in jms queues, so, like, that you can carry your data too.

• Transform the query inside cfscript to not access java objects

  When I downloaded my page, now my Web host says my questions to access java objects is not allowed. I can't find out how to change these queries, so that they do not use a java object.

  This is one of my questions. My other questions are in the same format:

  objFactory1 = CreateObject(
  "java",
  "coldfusion.server.ServiceFactory"
  );
  
  // Get the Data Source service from the service factory.
  objDataService1 = objFactory1.DataSourceService;
  
  // The data service object has access to all data sources
  // running on the server. Let's get a connection to our
  // datasource before running the query.
  objDataSource1 = objDataService1.GetDataSource(
  "myapp"
  );
  
  // Open the connection. Here, we have the option to pass
  // in a username and password. Since I am on the dev
  // server, no need to do so.
  objConnection1 = objDataSource1.GetConnection(
  // USERNAME, PASSWORD if needed //
  dsnlogin,dsnpwd);
  
  // Prepare the SQL statement that you want to run. Much
  // harder than the CFQuery tag, but not impossible.
  getevents = objConnection1.PrepareStatement(
  "SELECT " &
  "dtstamp, " &
  "eventname " &
  "FROM " &
  "events " &
  "WHERE MONTH(DATE(dtstamp)) = " & CurMonth & " AND DAYOFMONTH(DATE(dtstamp)) = " & i
  );
  
  // of object that we are all used to working with.
  getevents = CreateObject(
  "java",
  "coldfusion.sql.QueryTable"
  ).Init( getevents.ExecuteQuery() );
  
  // Close the connection.
  objConnection1.Close();
  
  

  I'm back the columns like this: getevents.eventname [intRow]

  I think I got it. Here is the solution for anyone who runs into the same problem

  q = new Query();
  
  q.setDatasource( "myapp" );
  
  // build the SQL statement
  //q.setSQL( "SELECT eventname FROM events WHERE MONTH(DATE(dtstamp)) =  :themonth AND DAYOFMONTH(DATE(dtstamp)) = :theday" );
  
  q.addParam( name="themonth", value=#curmonth#, cfsqltype="CF_SQL_INTEGER" );
  q.addParam( name="theday", value=#i#, cfsqltype="CF_SQL_INTEGER" );
  
  // run the query and get a query object
  getevents = q.execute(sql="SELECT * FROM events WHERE MONTH(DATE(dtstamp)) =  :themonth AND DAYOFMONTH(DATE(dtstamp)) = :theday").getResult();    
  

  Loop over the query results

  for (
  intRow = 1 ;
  intRow LTE getevents.RecordCount ;
  intRow = (intRow + 1)
  )
  
  {
  getevents.eventname[intRow]
  
  }
  

  Not as difficult as I thought, just REALLY long to find the solution.

• invoke the button action or a java script page

  Hello
  
  I wanted to call a java script button action. I created a button associated with a request. The button action should redirect to an existing page. I did the hidden button. I would like to call a java script function button. Can someone point me to a thread with the syntax which handles this.
  
  Or is it possible to directly call a function of java script to a page?
  
  Thank you

  In a javascript function, you can set the property from 'rental' of the window object to point to the APEX page as in the example below. How you call this function from the Applet javascript I don't know.

  function goToPage(pageno) {
  var str="f?p=101:" + pageno + ":&SESSION."  // 101 is the APEX application id
  window.location=str;
  }

• Houston-25036: an invalid object operation was drawn to the View object type.

  Hi all
  
  I use version jdev 11.1.2.2
  
  I have an application module impl in which I have a method to call a pl/sql that calls an external API.

    public String create(String productId, String component)
  {
      String createMessage=null;
      DBTransaction dbtransaction = (DBTransaction)getTransaction();
      StringBuffer str = new StringBuffer();
         str.append(" BEGIN ");
      str.append(" api.database@test ( ");
      str.append(" p_number                    => :1,   ");
      str.append(" p_product_id               => :2,   ");
      str.append(" p_component                => :3   ");
      str.append("    ); ");
      str.append(" END; ");
  
      CallableStatement callablestatement = dbtransaction.createCallableStatement(str.toString(), 1);
  
      try {
        callablestatement.registerOutParameter(1, Types.INTEGER);
        callablestatement.setInt(2, Integer.parseInt(productId));
        callablestatement.setString(3, component);
        callablestatement.executeUpdate();
        dbtransaction.commit();
        createMessage = callablestatement.getObject(1).toString();
        if (callablestatement != null) {
          callablestatement.close();
        }
        if (dbtransaction != null) {
          dbtransaction.closeTransaction();// closing connection
        }
  } catch (Exception e) {
        e.printStackTrace();
      }
  
      return createMessage;
  }

  I returns a value of this class of impl. I call this form of method a bean customer interface through. Then, I want to display another page passing the return as a variable binding value to another object to display grace to perform with the workflow setting.

    public void callCreate(ActionEvent actionEvent){
      BindingContext bctx = BindingContext.getCurrent();
      DCBindingContainer bindings = (DCBindingContainer)bctx.getCurrentBindingsEntry();
      DCDataControl dataControl = bindings.findDataControl("ReportAMDataControl");
      ReportAM ReportAM = (ReportAM)dataControl.getApplicationModule();
      createMessage =
          ReportAM.createBug(product, component);
        FacesContext context = FacesContext.getCurrentInstance();
        context.getApplication().getNavigationHandler().handleNavigation(context, null, "goExecute");//navigate to next page
  }

  Everything is going very well when I'm not closing the db connection in the impl.
  
  but when I close the db connection is showing the following error.

  like I said with ADF BC, we never explicitly close the DB connection (framework takes care for this).

• I might be breaking the java.io.InputStream javadoc specifications

  * [note] *: this is not intended to be a fully functional class at the moment. Step by step I am learning how to extend an existing class and create one that could be useful someday. 'Close()' being the simplest method of InputStream, I start here.
  
  This InputStream made a number any of files in a directory look like one big file. I continue to read until the last file to read what EOF is reached.

  public class DirectoryInputStream extends InputStream {
    private boolean moreFiles = true;
    private int inputFileNmb = 0;
    private File[] files;
    private InputStream inStrm;
    private InputStream[] holdOntoOpenStreams;
  
    public DirectoryInputStream(File dataSrc) throws Exception {
      files = getFilesInDir(dataSrc);
      // holdOntoOpenStream = new FileInputStream[files.length]; <-- towards maintaining the integrity of "close()"
      chngFile();
    }
  
    private void chngFile() throws IOException {
      if(inputFileNmb != 0) inStrm.close();  // <-- violates integrity of "close()". Don't do this if the javadoc for close() is to be followed
      inStrm = new FileInputStream(files[inputFileNmb]);
      // holdOntoOpenStreams[inputFileNmb] = inStrm; <-- could be used to hold onto open InputStreams until close() is called
  
      inputFileNmb++;
      if(inputFileNmb == files.length) moreFiles = false;
    }
      
    public int read() throws IOException {
      // code removed that deals with returning System.getProperty("line.separator") if the EOF of a file is reached and there are other files still to be read
      int c = inStrm.read();
          
      if((c == -1) && !moreFiles) {
        inStrm.close();  // <-- violates integrity of "close()" ?
        return -1;
      } 
  
      if((c == -1) && moreFiles) {
          // ...deal with transitioning inStrm to connect to a different file. "chngFile()" is invoked in the process, etc.
          c = inStrem.read();
      }
      return c;
    }
  
    // following the API specifications, this is what an overridden "close()" should look like?
    public void close() throws IOException {
      inStrm.close();
      for(int i = 0; i < (inputFileNmb - 1); i++) {
        holdOntoOpenStreams.close();
  
  }
  
  }
  
  }
  Internalizing the closing of streams into this class seems like a feature.
  Yet, As per the API "close()":
  *Closes this input stream and releases any system resources associated with the stream.*
  Certainly, I am not doing that.
  
  My opinion is that I am violating the java.io.InputStream specification,
  In OOP, you should never do this.
  But, this is an exception because the resources associated with open FileInputStream objects are too limited.
  
  --thank you

  The last FileInputStream is only closed automatically if the last file is read completely to expressions of folklore. You can't assume that. You can't assume the readings were made. You must close the file currently open, if there is one, in the close() method.
  		   

• Arg list and method of the signature object

  Hi all
  
  I have a doubt regarding the lists of arguments
  
  If I have these 3 methods:
  
  public void doubts (String info, object... args)
  
  Doubts public Sub (string info, string moreInfo)
  
  public void doubts (info from the chain, moreInfo, object... args)
  
  When I invoke:
  
  doThis ("yyyy", "bbbb")
  
  that will be called?
  
  I tried this and it will call doubts (news channel, string moreInfo) that seems logical.
  
  Actually there no way I can invoke the first method, at least I have use something other than a string as the second parameter
  for example: doubts ("yyyy", 5)
  
  My conclusion is therefore:
  
  "the compiler will try to"match"arguments as much as possible. the list of arg as a last resort'
  
  However, I would like to read this in a few 'official' somewhere doc, but I can't find any direct reference in google nor in the java lang spec.
  
  Can someone confirm my conclusion?
  
  Thank you

  The official documentation for this is the JLS.

  It is under [url http://java.sun.com/docs/books/jls/third_edition/html/expressions.html#15.12] 15,12 Expressions Invocation method, and in particular, [url http://java.sun.com/docs/books/jls/third_edition/html/expressions.html#15.12.2.5] 15.12.2.5 choice of the most specific method.

  Generally speaking, however, I would advise against each other an overload of the method signatures where it isn't intuitive writing one will be more accurate.

• Are there alternatives for the large objects through callback JMS?

  Hi, I am developing an application that uses JMS reminder to create this 'multi-threaded feel '. All's well if the data object returns of each MDB is relatively small, but as soon as we ended with the need to send back large objects (for example, an ArrayList of 250 objects k) of the MDB (with 20 MDB active at a given time), it breaks the app when the server ran out of memory when the MDB strikes the setObject method call on the response (server log see extract below). Is there any "known" for JMS problem managing large objects? Are there any other alternatives to recall JMS to create this 'multi-threaded' feature in WLS? Thanks in advance.

  It is your writing, you have put in place a use case when the application attempts to use on several large objects in parallel. The FMV is just short of the bunch. Looks like the same thing would be whether it's large objects JMS messages, or another type of object...

  Some ideas: (A) release the memory JVM - possibly by setting pagination (see chapter JMS of the Performance and Tuning Guide), (B) reduce the size of the async message line (search for "MessagesMaximum") in the same guide, (C) increase the memory to the JVM, (D) see if its possible to decompose each large into several small objects/messages object, but perhaps especially (E) do not expect to be able to have multiple threads each operate on a very large object separate simultaneously - each object necessarily consume memory while it is accessed - seriously consider reducing the number of concurrent threads according to chapter MDB of the Performance and Tuning guide.

• Why did the Java script works on my work for Internet explore, but not for Firefox RSS feeds?

  I finished building the Web site for my girlfriend, and the rest is the RSS feed. It works just fine in IE 8, but Fire Fox 9 when the widget is clicked a bookmark box appears and asks if I want to save it as a bookmark. I'm not a programmer of the Java script so I hope help here! Here's the script:

• "< a href ="http://www.susangabrielle.com/1/feed"title ="RSS"alt ="rss">< /a >"

The view is http://www.susangabrielle.com

Probably you fixed, the RSS seems to work for me
