Using JPDA with Oracle9i Application Server for JSP Debugging

To use JPDA debugging protocol, you'll need to modify the parameters you send to the JVM, tell the server how to find the JDPA library, and modify the CLASSPATH for Oracle9i Application Server (9iAS).

These changes must be made on the computer that is hosting 9iAS. You will need administrator or root permission to make these changes.

Setting parameters

• In jserv.properties, set the wrapper.bin parameter to:

  wrapper.bin.parameters=-classic
  wrapper.bin.parameters=-Xdebug
  wrapper.bin.parameters=-Xnoagent
  wrapper.bin.parameters=-Djava.compiler=NONE
  wrapper.bin.parameters=-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5000
  

  For the invocation options for JPDA, see the Sun VM Invocation Options.

  If you are running on Solaris, you may also need to include stdalloc=y as part of the -Xrunjdwp parameter, like the following:

  wrapper.bin.parameters=-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5000,stdalloc=y

Adding the JPDA library

• In jserv.properties, set wrapper.path to include the location of jdwp.dll (This file is is part of the Java Platform Debugging Architecture):

  wrapper.path=D:\jpda\bin

• If Apache JServ is running on Unix:

  setenv LD_LIBRARY_PATH /home/jpda/lib/sparc:$LD_LIBRARY_PATH
  setenv PATH /home/jpda/bin:$PATH

  where home/jpda is the path to your JPDA installation. In addition, you will have to pass that environment variable through Apache to the JVM. To do that, in jserv.properties, add the following line:

  wrapper.env.copy=LD_LIBRARY_PATH

Setting the CLASSPATH

1. In jserv.properties, set wrapper.classpath to:

wrapper.classpath=C:\Oracle\iAS\Apache\jdk\lib\tools.jar
wrapper.classpath=C:\Oracle\iAS\Apache\Jsdk\lib\jsdk.jar
wrapper.classpath=C:\Oracle\iAS\Apache\Jsdk\lib\ojsp.jar
wrapper.classpath=C:\Oracle\iAS\Apache\Jsdk\lib\servlet.jar
wrapper.classpath=C:\Oracle\iAS\Apache\Jsdk\lib\ojc.jar

2. Make sure that the location of ApacheJServ.jar is specified:

wrapper.classpath=C:\Oracle\iAS\Apache\Jserv\ApacheJServ.jar
