Using Oracle's JVM with Oracle9i Application Server for JSP Debugging

To use Oracle's JVM debugging protocol, you need to change the JVM that Oracle9i Application Server (9iAS) uses, modify the parameters you send to the JVM, and modify the CLASSPATH for Apache JServ.

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

Changing the JVM

• In the jserv.properties file, set the wrapper.bin parameter to the full path of the JDeveloper JVM (java.exe). For example:

  wrapper.bin=C:\Oracle\iAS\Apache\jdk\bin\java.exe
  

Setting parameters

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

  wrapper.bin.parameters=-XXdebugondemandquietport4000

  The -XXdebug parameter options are the following:

  ondemand

  Start the java program right away and allow a debugger to connect any time. The default is the Java program stays halted until a debugger is connected.

  port4000

  Debugger must connect at the specified port. The default port is 4000.

  quiet

  Don't print connection messages. The default is connection messages are sent to standard error.

Changing the ApJServAction entry

• In jserv.conf comment out any existing ApJServAction .jsp entries by putting a # at the beginning of the line:

  #ApJServAction .jsp /servlets/org.gjt.jsp.JSPServlet

  Then add a new ApJServAction .jsp entry:

  ApJServAction .jsp /servlets/oracle.jsp.JspServlet
  

Adding servlet init parameters

• In the servlet init parameters section of the zone.properties file, add the following lines.

  servlet.oracle.jsp.JspServlet.initArgs=emit_debuginfo=true 
  servlet.oracle.jsp.JspServlet.initArgs=jspcompiler=oracle.jdeveloper.jsp.JspOjcCompiler 
  servlet.oracle.jsp.JspServlet.initArgs=classpath=D:\Oracle\iAS\Apache\jdk\lib\tools.jar

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
