Development steps

1. Download Related Standard Packages
   fndutil.jar
   fndcp.jar
   fndctx.jar
   Download Directory $ JAVA_TOP / ORACLE / APPS / FND / JAR / JAR /

2. Write a Java class
   Define the package name rules:
   a. If there is only a simple Class class after completion, the path to the registration is defined and the path to the server is consistent, such as package oracle.apps.hqc; the class file needs to upload to $ java_top / oracle.Apps.hqc / directory ;
   b. If the project is more complicated, it is best to pack it into JAR, then upload it to the directory specified by the server.
   Class description:
   Your own class must implement the JavaconCurrentProgram interface, and implement concurrent integral functions Runprogram (CPContext CTX)

3. Release registration
   3.1 Release Java Program
   a. If there is only a simple Class class, upload it to the server's package name, such as package oracle.apps.hqc; the class file needs to upload to $ java_top / oracle.apps.hqc / directory, concurrent manager Automatically find the class file;
   b. If the program is packaged into a JAR package, you can upload it to the directory specified in $ java_top, and then there are two ways to reference the JAR package:
   Method 1: Modify the ClassPath and AF_CLASSPATH in USAPL_TOP / Admin / Adovars.env, add the absolute path of JAR to the JAR, and then restart the concurrent manager.
   Method 2: Add the following to the options for concurrent procedures:

-classpath <path_to_your_custom.jar>/custom.jar:<path_to_JAVA_TOP>:<path_to_appsborg.zip>/appsborg.zip 
 --- Absolute path 
<path_to_appsborg.zip> = $COMMON_TOP/java/lib/appsborg.zip 
 E.g:
-classpath /u1/TEST52/apps/apps_st/comn/java/classes/hqc/Loadjava/EBSExcel.jar:/u1/TEST52/apps/apps_st/comn/java/classes:/u1/TEST52/apps/apps_st/comn/java/lib/appsborg.zip

3.2 Concurrent request registration

Performing method: java concurrency program
Executive file name: Classification
Perform file path: package name

Concurrent request sets the same procedure, slightly

4. Example

package oracle.apps.hqc;

import oracle.apps.fnd.cp.request.CpContext;
import oracle.apps.fnd.cp.request.JavaConcurrentProgram;
import oracle.apps.fnd.cp.request.LogFile;
import oracle.apps.fnd.cp.request.ReqCompletion;
import oracle.apps.fnd.util.NameValueType;
import oracle.apps.fnd.util.ParameterList;

public class TestHqc implements JavaConcurrentProgram {

    @Override
    public void runProgram(CpContext ctx) {
        / / A list of parameters that acquire concurrent program incoming
        ParameterList lPara = ctx.getParameterList();
        ReqCompletion lrc = ctx.getReqCompletion();
        try
        {
            // Print the value of the parameter name and parameters in log and output, respectively, in LOG and OUTPUT
            while(lPara.hasMoreElements())
            {
                NameValueType nvt = lPara.nextParameter();
                ctx.getOutFile().writeln(nvt.getName() + ":" + nvt.getValue());
                ctx.getLogFile().write(nvt.getName() + ":" + nvt.getValue(), LogFile.STATEMENT);
            }

            / / After completing the procedure of the print, the end status of the setup program is normal. If this step does not do, although the program has no error, the execution result is still an error.
            lrc.setCompletion(ReqCompletion.NORMAL, "Normal Ending");
        }
        catch(Exception e)
        {

            / / If the program has an exception, the execution result of the setup program, it should be set to Error
            ctx.getLogFile().write(e.toString(), LogFile.STATEMENT);
            lrc.setCompletion(ReqCompletion.WARNING, "Exception Occurs!!!");
        }
    }   
}

5、FQA

1) IDEA packaging JAR operation error
Exception in thread “main” java.lang.SecurityException: Invalid signature file digest for Manifest main attributes
Solve: Open the JAR package using the compression software: All the other files other than the MAINFEST.MF, .RSA and Maven folders in the meta-inflicity

2) Use high version JDK to report
java.lang.UnsupportedClassVersionError: com/oppo/ebs/DemoHqc : Unsupported major.minor version 52.0
Solve: Change JDK1.6 package
