• java.lang.NoClassDefFoundError when calling a java class of BPEL

  Hello

  I'm calling a java class to convert JSON to XML using BPEL. I imported all the necessary jar files in the project and compile successfully done.

  But while running, I get the java.lang.NoClassDefFoundError: net/sf/json/JSON error.

  For this, I placed all the necessary pots under the path FUSION_HOME/Oracle_SOA1/soa/modules/oracle.soa.ext_11.1.1/ and restarted the server.

  But still, I get the same error when running.

  A I missed a step? Let me know the procedure to solve this problem.

  I have to run ant or change the file manifests after placing the pot?

  in a site I find that we must place the pots under < DOMAIN HOME > directory / lib. Is this correct?

  We use SOA suite 11.1.1.6.

  Thank you

  Hello Terry,

  I'm not quite sure of what exactly would be the problem. Please go through this link and see if it helps: integrating Java and Java EE Code in a BPEL process

• How can I change the data stored with JDeveloper Java classes?

  Hello!
  First of all, I am experienced PL/SQL coder, but I'm quite beginner what comes to Java.
  JDeveloper is also a new tool for me and the reason why I am interested, it's the good Java Editor.
  With the good Java editor I can create classes and store them in the Oracle database and executing those inside PL/SQL code.
  
  I am currently faced with a minor problem, and I'm not able to find the answer to this:
  How can I change/edit/create stored with JDeveloper, Java classes to database (Toad for Oracle can do but it's not good editor Java)?
  
  I can navigate to Java classes with database browser, but I can't change those. Just view and drop it.

  JDeveloper is not a direct modification of the classes inside the database. Instead, you must change your java classes locally (including the management of versions, unit tests etc.) and then load them into the database. Load in the datab ase could be done using the Loadjava and the deployment profile stored procedure Java (file-> New-> General-> profiles of deployment-> Loadjava and Java Stored Procedures). I think it's even better let your build tool do the work. An example of task of Ant describing this is shown at http://davidmoten.blogspot.com/2007/11/oracle-loadjava-ant-task.html (I have not tried this, but have used a similar approach in a project)

• When the external program C and Java Class loaded in a schema

  Hi all
  I understand that both an external C program and a Java class are loaded after two of them are called in the PL/SQL environment, once they are published and loaded into shared libraries. Is this correct?
  
  Best regards
  Val

  An external procedure is never loaded into a schema. Oracle calls the external program.

  A Java class that is part of a Java stored procedure, however, is charged as a PL/SQL procedure is created - at compile time.

  The correct syntax for PORCEDURE4 is:

  No it's not. I already gave the correct syntax, which apparently ignored you.

  I don't know how can pass these parameters to this method.

  My question is clear?

  It is clear that you are interested in reading the documentation. All the answers are there.

  You're mixing two things:

  (1) creating the procedure (once), and I already told you how to do it

  (2) the procedure call

  For 1)-do you only once :

  CREATE OR REPLACE PROCEDURE REPORT4)

  LEVELS IN NUMBERS

  NODEID NUMBER

  CHILDBED_OLD NUMBER

  CHILDBES_OLD NUMBER

  CHILDMANDE_OLD NUMBER

  )

  AS

  JAVA LANGUAGE

• Load java classes in ORACLE database error: () Ljava/util/list ;) catch_type not a subclass of Throwable

  Hello

  I tried to load java classes in the database using the loadjava tool, but I get a warning which causes an error when calling the java method of procedure PLSQL.

  ERROR: ORA-29552: check warning: java.lang.VerifyError: (class: method com/mq/RIMSmqToolsIn,: mqRead signature: () Ljava/util/list ;) catch_type not a subclass of Throwable)

  I think that it is a problem of dependencie for some missing java classes that need to be solved using loadjava tool but I could not understand what pot should be used and how is the correct command with laodjava?

  NB: I tried to use a jar file that contains java.util.List.class, but I still get the warning when loading

  Thank you very much

• pl/sql appellant java class member function obtains ora-00932 in 11g.

  Call a member function of class of java from a pl/sql script, I get an error ora-00932.

  ORA-00932: inconsistent data types: waiting for an IN argument in position 1 which is an instance of an O

  convertible to an instance of a user defined class Java got a type of Oracle that could not be converted

  The code works fine when the java function is declared static.   However, since there could be thousands of users hitting the function at the same time and there is no instance of the object, I wasn't sure if it would be a matter of how oracle manages memory for each user in a session, if it would not be a problem, I can go forward with this approach.   However, I have greatly simplified this for an example that reproduces the problem.

  Create the oracle type:

  CREATE OR REPLACE TYPE MyObject AS OBJECT

  (

  col1Data VARCHAR2 (10),

  MEMBER FUNCTION createData

  RETURN VARCHAR2 AS LANGUAGE JAVA

  NAME "java.lang.String return MyObject.createData ().

  );

  Java code:

  CREATE OR REPLACE AND FIX JAVA SOURCE NAMED 'MyObject' AS

  import java. IO;

  public class MyObject

  {

  private String col1Data;

  public void createData)

  {

  System.out.println ("col1:" + col1Data);

  }

  }

  Java function call vai pl/sql function:

  FUNCTION to CREATE or REPLACE fn_myobject

  (col1 IN varchar2)

  RETURN VARCHAR2

  AS

  p_rc varchar2 (100);

  myObj MyObject;

  BEGIN

  myObj: = new MyObject (col1);

  p_rc: = myObj.createData ();   -This line gets an error 00932

  RETURN p_rc;

  END;

  /

  And finally, the script from sqlplus to test:

  Set serverout

  call dbms_java.set_output (50);

  Set line 120

  declare

  VARCHAR2 (64) RC: = ";

  R1 varchar2 (64): = 'abc ';

  Start

  RC: = fn_myobject (r1);

  end;

  /

  I tried all sorts of things without success.   Any ideas on this would be most appreciated.  It is once again, 11g.

  Thank you.

  MarkF says:

  If you go back to the example code I posted, it is mapping a java class oracle object.

  No, it isn't.

  Your example simply sets an Oracle object type whose member createData function is implemented in Java.

  The fact that the implementing class has the same name does not have a direct mapping between the class and the type of Oracle.

  The important part to read and understand in the link I posted is:

  A call specification outlines the top level of an Oracle database Java method entry point. So, you can publish only public static methods.

  However, there is an exception. You can publish instance methods as members of an SQL object type methods.

  You are in the first case.

  To be in the exceptional cases and be able to publish instance methods, the Java class must implement SQLData.

  See the latest example here:

  https://docs.Oracle.com/database/121/JJDEV/chsix.htm#JJDEV13273

  Adapted to your example:

  CREATE OR REPLACE AND compile JAVA SOURCE NAMED "MyObject" AS
  import java.sql.*;
  
  public class MyClass implements SQLData
  {
    // Implement the attributes and operations for this type.
    private String col1Data;
  
    public String createData ()
    {
        System.out.println ("col1: " + col1Data);
        return col1Data;
    }
  
    // Implement SQLData interface.
    String sql_type;
  
    public String getSQLTypeName() throws SQLException
    {
      return sql_type;
    }
  
    public void readSQL(SQLInput stream, String typeName) throws SQLException
    {
      sql_type = typeName;
      col1Data = stream.readString();
    }
  
    public void writeSQL(SQLOutput stream) throws SQLException
    {
      stream.writeString(col1Data);
    }
  }
  /
  

  CREATE OR REPLACE TYPE MyObject AS OBJECT
  (
    col1Data  VARCHAR2(10),
    MEMBER FUNCTION createData
            RETURN VARCHAR2 AS LANGUAGE JAVA
      NAME 'MyClass.createData() return java.lang.String'
  );
  /
  

  Test:

  SQL> exec dbms_java.set_output(1000)
  
  PL/SQL procedure successfully completed.
  
  SQL> set serverout on
  SQL>
  SQL> select MyObject('ABC').createData() from dual;
  
  MYOBJECT('ABC').CREATEDATA()

• Know Java classes and subclasses

  I m working with Forms & Report 10 gr 2.
  
  I m working with Forms & year Report 1,997. Normally, I flip between different application 8 or 9. My applications now appear a bit old-fashioned. Looking to solve this problem, I found an article by Grant Ronald, I think well know in this forum and it solved me a question that I post here. In this article Grant said:
  
  Extend the user interface forms
  So, how can you achieve the balance to give your
  Application Forms of the makeover to match the 21
  century without having to embark on an extensive program of
  refurbishment or recycling of the user?
  The answer lies in the architecture of Oracle Forms.
  For a form that runs via a browser, application the
  the user interface is rendered as a Java applet. This Java applet
  includes a number of officials of the Java classes
  each of the components of UI forms made. Magic
  lies in the fact that, since each component of the interface user is, indeed,
  a Java class, it can be subclassed. This means that you can
  create your own component that does all the
  component base, but with your own code to change
  the functionality or appearance.
  
  Really a piece of gold, in this regard, it will give you the key can change the forms look & feel.
  
  But, now, come the questions, how can I do this? How do I know what forms of using classes to display a button for example, what I need to do for subclasses?
  is there an example or documentation that can help me? If yes ¿where? One of the gurus can give me some links to explore this?
  
  Thank you & considers everyone.

• Location in the Java class

  Hi all
  
  I have the location in my pages jspx with two PortalBundle.xlf & PortalBundle_fr.xlf files. It works very well. I use an ApplicationBean.java and a CustomPhaseListener.java of classes. To call them, I use this variable set in the jspx pages:
  
  < c:set var = "portalBundle" value = "#{adfBundle [' portal.]}" {[PortalBundle']} "/ >"
  
  and this line to have the correct text:
  
  < af:outputLabel value = "#{portalBundle.LANGUAGE}" / >
  
  In the project properties Panel, I put the ressourceBundle to the Portal. PortalBundle
  
  But now I do the change on this label and I want to access the portalBundle java class. I tried with these solutions:
  
  Res ResourceBundle = ResourceBundle.getBundle ("PortalBundle");
  String textEmployee = res.getString ('LANGUAGE');
  
  But the application is unable to locate the ressourceBundle... and there my locale by default rather than the ApplicationBean locale.
  
  Thanks for your help!
  
  PS: I used this tutorial video to locate my jspx pages: http://www.youtube.com/watch?v=ha6FzOkVc24

  Hi, Maxim.

  To take your package of Java resource classes follow the next steps:

  -Save in faces - config.xml your support and default locale. Remember that you must have a file with a suffix [local] yourPortalBundlePackage.PortalBundle_ that you saved.

  
    es
    en
    en
    es_ES
  
  

  -Save a var that is pointing to your resource group: for example:

  
    com.merchan.portal.PortalBundle
     portalBundle
  
  

  -Now from Java Code, you can access your packages with the following user mode:

  public static String getStringFromBundle(String key, String varName) {
        FacesContext ctx = JSFUtils.getFacesContext();
        ResourceBundle rb = ctx.getApplication().getResourceBundle(ctx, varName);
        return rb.getString(key);
  }
  
  // USE
  JSFUtils.getStringFromBundle("HOME","portalBundle"); // If you have a JSFUtils and ADFUtils register this static method there. These classes are very useful

• How to pass an argument to a standalone java class JDeveloper

  For the experienced:
  
  In JDeveloper when you write a java class with a main() method that takes no arguments, you just click with the right button on the java file and choose run to run the program. But suppose the main() method takes arguments, how to move your arguments to the program? This is especially a problem I use the studio version of JDeveloper (10.1.3.4 and 11.1.1.3 Versions) that each uses the version of the JDK included with, rather the JDK (which is yet another different version) installed at the level of the OS on the PC.
  
  Thanks a lot for your help!
  
  
  Newman

  Hello

  If you mean how to pass arguments in JDeveloper:
  Tools > Project Properties > run/debug > change the default run Configuration (or create a new) > settings start > program Arguments - here you can set arguments

• Failed to instantiate the java class for custom filter

  I created a filter for the AAU and installed under Server, custom, AlterPrefix, classes. However, I got following error when checking in the file:
  
  < Undefined > content item has not been verified successfully. Impossible to filter 'AlterPrefix.CustomFilter' of type 'validateStandard '. Failed to instantiate class code java to 'AlterPrefix.CustomFilter' to the 'AlterPrefix.CustomFilter' site with the default location to "AlterPrefix.CustomFilter".
  
  I have to pass the classes for the classes of server /, then the filter works.
  
  I would like to be in the server/custom. Is that all that I'm missing?
  
  It had file looks like:
  

  @ResultSet Filters
  4
  type
  location
  parameter
  loadOrder
  validateStandard
  AlterPrefix.CustomFilter
  null
  1
  @end

  @jschultz is correct...

  In your generation of component settings, you must click Advanced, and then add the classpath element. In your component definition file (MyComponent.hda), you should see a line like this:

  classpath = $COMPONENT_DIR/classes

  Then, you need to disable and re-enable your component. If you do this, you should see classpath you of the component in the file 'ucm/config/state.cfg '. Then you know that it is in the classpath during the launch of the Complutense University of MADRID.

  Now... If you STILL have problems of not being able to instantiate the Java class, the most common problem is a misspelling of the Java class. Check everything, preferably with a new set of eyes.

  Another problem is that despite assertions to the contrary, if you compile your Java classes with a version of the JVM and they instantiate by reflection with a different version of the JVM, then you get sometimes weird class not found"exception. Be sure to compile your code with the same EXACT of Java version that runs UCM.

  Two things:
  1. check that you have moved the code of the application server and database server
  2. check the path (spaces, upper/lower case etc.)
  3. check the permissions of the file.

  If all goes well, then make a backup of existing on the server controller and redeploy the file (compile the file in Jdeveloper, after removal of the myclasses directory). Bounce the server.

  An exception occurred when instantiating a java object. The cause of this exception was that: coldfusion/sql/QueryTable.
  
  If I try to run QueryUtil.java with eclipse it all works.
  
  Also, I tried to return a java.sql.ResultSet directly to coldfusion.sql.QueryTable.init () with failure.
  
  Do you know another solution?

  Thank you cf_dev2

  This is the solution:

  If you are using another jar file in your java.class, you must write the path of the jar in the jvm classpath:

  -Open C:\CFusionMX7\runtime\bin\jvm.config with a text editor;
  -Add at the bottom of the path full fo your jar files
  -Save
  -coldfusion restar

  I thing you can also add the classpath in coldfusion administrator, but I do not know how;

  I found only CF classpath.

  Hi all.
