1. Change to the directory of your sender processor.

2. Use the Java compiler by defining the -classpath parameter with the required libraries to compile the customized class.

   cd /work/custom
   mkdir customclasses
   /usr/jdk141/bin/javac -classpath .:/opt/sybase/EAServer/repra/
   lib/repraconn.jar -d customclasses com/mycompany/SampleClient.java
   

3. Verify the compilation.

   When the compilation finishes without any error messages, go to the customclasses directory to verify that SampleClient.class is under com/mycompany.

To use a jar file that includes the customized sender processor, go to the customclasses directory and use the jar command to build a jar file from the com directory. Otherwise, you can use the directory path to set up your environment.

Sybase recommends that you use jar file format for the customization.

1. Build a jar file.

2. • For EAServer:

     1. Copy the jar file or the directory structure containing the Java classes created from the previous step to the EAServer or java/classes directory.

     2. If you are using the jar file, start EAServer and connect to it from EAServer Manager.

        Go to the Servers/<your server> directory and right-click the Server Properties menu. Select the Java Classes tab and click Add to add the name of the jar file, such as mycustom.jar. Click OK.

     3. Add repra.con.jar to the Server Properties.

   • For WebLogic:

     1. Shut down the application server if it is running.

     2. Modify the $BEA_HOME/repra/bin/repra_env.sh file to add the full path of mycustom.jar or the customclasses directory to the end of the CLASSPATH definition.

        set CLASSPATH=/work/custom/customclasses:$CLASSPATH
        or 
        set CLASSPATH=/work/custom/customclasses/mycustom.jar;$CLASSPATH
        

     3. Start the WebLogic Server to activate the new environment change.
