• concurrent writes to a logfile from multiple threads (Java 7)?

  Hello everyone

  I have a multi-threaded Java 7 (jar file) program that uses JDBC to perform work (he uses a fixed pool of threads).

  The program works very well and it records things that it moves the console command shell window (System.out.printf ()) starting from multiple concurrent threads.

  In addition to the release of the console, I also need to add the capability of this program write in a single flat ASCII text file journal - starting from multiple threads.

  The output volume is low, the file will be relatively low because it is not a data file, a log file.

  Can you please suggest a relatively simple and good to achieve design/approach using Java 7 features (I have not yet Java 8)?

  The code examples would also be appreciated.

  Thank you very much

  Use a dedicated thread for logging and a queue to source it. See the "queue implementations of the trails in the Java tutorials for the use of queues and the code example that works.

  https://docs.Oracle.com/javase/tutorial/collections/implementations/queue.html

  Java has several classes of queue synchronized you can use if those in this tutorial are not suitable for your use case. Here's just one:

  https://docs.Oracle.com/javase/7/docs/API/Java/util/concurrent/ConcurrentLinkedQueue.html

  Unlimited thread-safe queue based on linked nodes. This queue orders elements FIFO (first-in-first-out). The head of the queue is this element which remained the longest the queue. The tail of the queue is this element that has been on the queue as quickly as possible. New elements are inserted at the tail of the queue, and get the recovery operations of the queue of the elements at the head of the queue. At ConcurrentLinkedQueue is a good choice when the number of threads will share access to a common collection. Like most other concurrent collection implementations, this class does not allow the use of null elements.

  Using a queue your current code can add recording which is FAST because it is add an instance of the class to a collection rather interact with the file system. And your current code requires NO knowledge of the functioning of the system of newspaper, that it connects or when and where it connects.

  For your use case use you a synchronized queue and edit each of your worker threads to add their log data to the master queue used by the newspaper for the logging thread.

  You shouldn't have multiple threads trying to write directly in the same file.

  The entire point of the modular and multi-processing programming is to BREAK dependencies between modules of code.

  The logging system must be INDEPENDENT of the other code and your current code must NOT have ANY need or knowledge of the file system or OF the specificity of the way where, or when the data is actually stored.

  Your code must run simple and minimal logging by adding its data to a queud. Once the log data was added to the queue and then, as far as your code is concerned, that data has been noted. It should be ONLY module log to determine the LOCATION to save the data, HOW to record data and even WHAT information to log.

  You can add the larger newspapers in the future: newspapers, paper 1) different levels of 2) to a remote server or the database 3 send some events in the log.

  I suggest you create a SIMPLE D.O. (data object) to maintain the log info (attributes like gravity, time/date, type of exception stack, error, etc.). Then create a class of SIMPLE log with several overloaded methods: a method that takes a single parameter, with two, etc. Javas is owner of exception classes have some simple examples of both simple and complex, nested exception handling.

  These methods journal would take care to fill in the NEWSPAPER to DO correctly and then placing the instance of the D.O. to the journal queue. In this way, you can use a parameter of a simple newspaper just pass an error message and the log class method will add a default severity level (which can vary from thread if you want), time (which can range from wire) and other necessary data.

  The goal is to keep the journal interface use you in your existing code as SIMPLE as possible while keeping as independent as possible of the actual logging mechanism.

  The result is a mechanism of simple logging that is versatile and scalable and can then be used for your PROJECTS that require a registration (file, database, e-mail).

  Do not make the mistake to hardcode the mechinism journal in your existing code.

  DO not continue independent, modular architecture that you already use.

• Read configuration data source AM from Java Bean code

  Hi experts,

  
  I use Jdev 12.1.3 and I need to read the name of AM Datasource from Java Code, to get a text like "jdbc/nomsourcededonnees.

  
  Is this possible?

  Thank you very much
  Jose.

  This object has methods getURL(), getUser() and others.

  But there is no method as getDataSourceName()

  (AFAIK, jdbc connection "knows" nothing about the Data Source)

  You can try something like this inside your AppModuleImpl class:

  this.getSession () .getEnvironment () .get (Configuration.JDBC_DS_NAME)

• 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

• Aggregation of data from multiple sources with BSE

  Hello
  
  I want to aggregate data from multiple data sources with a BSE service and after this call a bpel with a process of construction of these data.
  1 read data from the data source (dbadapter-select-call)
  2. read data from the data source B (dbadapter-select-call)
  3 assemble the data in xsl-equiped
  4. call bpel
  
  Is this possible? How can I get data from the first call and the second call to conversion data? If I receive data from the second call, the first call data seem to be lost.
  
  Any ideas?
  Gregor

  Gregor,

  It seems that this aggregation of data is not possible in the BSE. This can be done in BPEL too using only assigned but not using transformations. I tried to use transformations by giving the third argument to the function ora: processXSLT. But couldnot get the desired result.

  For more information on the passage of a second variable (of another schema) as a parameter to xslt pls refer to the post office

  http://blogs.Oracle.com/rammenon/2007/05/

  and the bug fix 'passage BPEL Variable content in XSLT as parameters'.

  Hope this helps you.

  Thank you, Vincent.

• Mapping of Java errors ActionScript errors

  I see the reference implementation and the Java API it is possible to define data error on the licence application using the values defined in the com.adobe.flashaccess.sdk.protocol.AdobeErrorData class, or customized using CustomErrorData values.

  I want to create a trial licenses server that can send error codes specific to the reader, so that I can better test my FAX error codes reader responses.

  To do this properly, I need to figure out how the errors described in the map of the Java API for the various ActionScript runtime error codes. Is there a document somewhere that binds the two? I would rather not give each object ErrorData individually from my license server to see what Flash Player & the FAXES runtime to do with it.

  Thank you

• 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.

• Update multiple columns from multiple tables in a single UPDATE request

  Hello

  I'm trying to figure if I'm heading in the right direction.

  I want to update multiple columns from multiple tables in a single UPDATE request. Also, I would like to update multiple columns in a table from the tables.

  Scenario 1

  UPDATE Table2, Table 3
  SET T2.Column1 = T1.Column1 
  ,T2.Column2 = T1.Column2
  ,T3.Column2 = T1.Column2
  FROM Table1 T1, Table2 T2, Table3 T3
  WHERE T1.id = T2.id
  and T1.id = T3.id
  
  

  Scenario 2

  UPDATE Table3
  SET T3.Column1 = T1.Column1 
  T3.Column2 = T1.Column2
  ,T3.Column3 = T2.Column3
  ,T3.Column4 = T2.Column4
  FROM Table1 T1, Table2 T2, Table3 T3
  WHERE T3.id = T1.id
  and T3.id = T2.id
  
  

  Hello

  For scenario 1, you must write separate instructions UPDATE table2 and table3.

  To guard against someone else change one of these tables while you act so you can copy all relevant data in a global temporary table and update this global temporary table table3.

  ENGAGE only when two tables have been changed.

  You can write a procedure or an INSTEAD OF trigger to do all this.

  For scenario 2, you can reference many tables that you need when new table3.  It might be more efficient and simpler to use the MERGER rather than UPDATED.  For example:

  MERGE INTO table3 dst

  WITH THE HELP OF)

  SELECT t1.id

  t1.column1

  t1.column2

  t2.column3

  t2.column4

  FROM table1 t1

  JOIN table2 t2 ON t1.id = t2.id

  )             src

  WE (dst.id = src_id

  WHEN MATCHED THEN UPDATE

  SET dst.column1 = src.column1

  dst.column2 = src.column2,

  dst.column3 = src.column3,

  dst.column4 = src.column4,

• The research of Web applications with fields of the Data Source that contains multiple values

  I have a Web application with a field that allows multiple values to be recorded similar to the list box. I need limit the allowed values for a large, over the list of the values currently stored in another Web application as a data source. I can not apply to the type of Data Source field that allows only single value selection. I also need to be able to use the search form Web App to search for items containing 1 OR more of the values in this field (a type of list control field search functionality). Here's what I tried to field types:

  • Text (String) or text (multi-line) field type - By saving a list of values separated by commas (outputs in the same way this list box) to an entry of text or textarea, the search only logic search exact string (including commas) and does not analyze individual values.
  • Type of list (checkbox) field - it allows me to search for multiple values using the logic of the GOLD, but the web application stores only the values that have been entered as an option in the field settings real web app. I tried to use a checkbox with minimal or empty options list, hoping that some values I sent more separate by a comma value chain would be still stored, but because the values come from my Web App data source and not stored with the field options list, they were not saved.

  Someone at - he found a way to do it?

  My other question is how can I use a multivalued field to similar as described above but return results containing the elements with ALL the values of this field (AND logic).

  Can someone enlighten me to the inner workings of the search BC logic web app?

  You don't need to use the predefined boxes or types of entries. Everything you can represent as a string (such as the values separated by commas in your example) can be saved in any field of webapp. The types of fields defined in the Web application are only used to translate internal representation (all channels) to the various user-friendly interpretations (checkboxes, radios, dates, links, etc.)

• Creating a display with a data source object

  Hello guys,.
  
  Is there a way to create a View object in JDeveloper 11.1.1.4.0 using an instead of a JDBC data source connection string? When I select new-->--> view object ADF business components, it seems that the Research Assistant for a default database connection.
  
  I wonder if there is a way to create a display object and specify something like ' java: comp/env/jdbc/xxxxDS ' as a data source. I know that the Module of the Application can be configured to point to a JDBC data source and then WLS can be configured to use the JDBC data source, but I wonder if it's the only way to go.
  
  Thank you

  I know that the Module of the Application can be configured to point to a JDBC data source and then WLS can be configured to use the JDBC data source, but I wonder if it's the only way to go.

  Yes, at design time you only use inside JDeveloper JDBC connections to connect to the DB and create components ADF BC - after all development is done alone without a WLS environment.
  At run time, your AM can be configured to use a data source or JDBC connection.

• Taskflow have model (using the view object instances) of two data sources

  JDeveloper Version: 11.1.2
  
  We have a flow of single task that has built pages on two modules of the Application that are based on two different data sources.
  If the default activity in the workflow uses a display Instance of AM belonging to a particular data source object.
  Browsing later, we reach a page that uses instances of object of another display AM belonging to a different data source, the framework does NOT deliver from the SQL statement against this source of data rather than the data source used in the default activity.
  
  How can it resolve to the appropriate data sources?
  
  Thanks in advance,
  Nini

  Nini,

  Yes, it's the way things are meant to run:

  Definition data control range for the workflow to the 'remote' change the behavior?

• Problems of creating Java object in JBoss environment

  We are migrating our application from one Oracle/IIS environment to a MySql/JBoss one and most of the things have been properly converted.
  
  However a Java object that is called from a page of the CF is not be created. I've looked everywhere and can't find no logging a problem. I see the classpath in the CF settings. The class runs as expected if called from the command line.
  
  Any ideas as to what to try or where to look for clues?

  Sorry for the late reply, thanks for the suggestions.

  The answer (for me) was to put the .jar files in the directory /cfusion.war/WEB-INF/lib rather than /cfusion.war/WEB_INF/cfusion/lib (which are listed in the class path). What makes this particularly annoying, it's that when you preview of CF settings there is no indication that my pot is in the class path. Well, it works.
