Help on "java.lang.NoClassDefFoundError: oracle/jsp/runtimev2/JspReportUtil"

Question

Hi all,
I encounted the following exception on a deployed project to ias 9.0.2:
500 Internal Server Error
java.lang.NoClassDefFoundError: oracle/jsp/runtimev2/JspReportUtil     at oracle.jsp.runtimev2.JspServlet.service(JspServlet.java:333)     at javax.servlet.http.HttpServlet.service(HttpServlet.java:336)     at com.evermind[Oracle9iAS (9.0.2.0.0) Containers for J2EE].server.http.ResourceFilterChain.doFilter(ResourceFilterChain.java(Compiled Code))     at oracle.security.jazn.oc4j.JAZNFilter.doFilter(JAZNFilter.java(Compiled Code))     at com.evermind[Oracle9iAS (9.0.2.0.0) Containers for J2EE].server.http.ServletRequestDispatcher.invoke(ServletRequestDispatcher.java(Compiled Code))     at com.evermind[Oracle9iAS (9.0.2.0.0) Containers for J2EE].server.http.ServletRequestDispatcher.include(ServletRequestDispatcher.java:108)     at com.evermind[Oracle9iAS (9.0.2.0.0) Containers for J2EE].server.http.EvermindPageContext.handlePageThrowable(EvermindPageContext.java:596)     at com.evermind[Oracle9iAS (9.0.2.0.0) Containers for J2EE].server.http.EvermindPageContext.handlePageException(EvermindPageContext.java:567)     at data.lookjjview._jspService(_lookjjview.java(Compiled Code))     at com.orionserver[Oracle9iAS (9.0.2.0.0) Containers for J2EE].http.OrionHttpJspPage.service(OrionHttpJspPage.java:56)     at oracle.jsp.runtimev2.JspPageTable.service(JspPageTable.java:302)     at oracle.jsp.runtimev2.JspServlet.internalService(JspServlet.java:407)     at oracle.jsp.runtimev2.JspServlet.service(JspServlet.java:330)     at javax.servlet.http.HttpServlet.service(HttpServlet.java:336)     at com.evermind[Oracle9iAS (9.0.2.0.0) Containers for J2EE].server.http.ResourceFilterChain.doFilter(ResourceFilterChain.java(Compiled Code))     at oracle.security.jazn.oc4j.JAZNFilter.doFilter(JAZNFilter.java(Compiled Code))     at com.evermind[Oracle9iAS (9.0.2.0.0) Containers for J2EE].server.http.ServletRequestDispatcher.invoke(ServletRequestDispatcher.java(Compiled Code))     at com.evermind[Oracle9iAS (9.0.2.0.0) Containers for J2EE].server.http.ServletRequestDispatcher.forwardInternal(ServletRequestDispatcher.java(Compiled Code))     at com.evermind[Oracle9iAS (9.0.2.0.0) Containers for J2EE].server.http.HttpRequestHandler.processRequest(HttpRequestHandler.java(Compiled Code))     at com.evermind[Oracle9iAS (9.0.2.0.0) Containers for J2EE].server.http.AJPRequestHandler.run(AJPRequestHandler.java:151)     at com.evermind[Oracle9iAS (9.0.2.0.0) Containers for J2EE].util.ThreadPoolThread.run(ThreadPoolThread.java(Compiled Code))
I found there is leak of memory resource on the Oracle RDBMS host while this problem occurs,the database host has only 512Mb RAM.And I once configred the database to worked on Shared Mode,in this case the database has less chance of memory leak,but the above exception occurs more often.So I have to change the database to work back on Dedicate Mode!It's hard to find any tips on my Exception as mentioned above.
And I want to know the working principle of servlet on iAS.When invoke a servlet,will the servlet be cached on Memory from the first request,or it will be clear up and re-inload until next request?I just wonder if the iAS server will run out of memory,because I noticed there is a memory configure option in "jser.properties" file.And the exception I encoutered seems to occur at a critical point.

Thanks but that did help since they are talking about
JDK1.3. I downloaded J2SDK-Beta 3 it says that you
don't need to set a class path variable. You need to be careful about how you interpret this statement. The rule is, if your system doesn't have a classpath set, you'll get a default of the current directory (.). If your system does have a classpath setting, then the setting will be used.
Just because you didn't set your classpath doesn't mean someone or some other application didn't. Make sure that your system doesn't have a classpath setting. If it does, you may need to add the current directory (.) to it.
