Issue/Introduction

When logging in to DX NetOps Portal,  the GUI fails to render with the following render functions listed:

Environment

DX NetOps CA Performance Management all currently supported releases

Cause

Looking at the SSService.log, seeing the following being repeatedly generated:

INFO | jvm 1 | 2026/06/16 10:51:02 | ERROR | qtp1371919599-30 | 2026-06-1610:51:02,210 | com.ca.im.portal.render.desktop.BaseRenderer
INFO | jvm 1 | 2026/06/16 10:51:02 | | Error including JSPs:
INFO | jvm 1 | 2026/06/16 10:51:02 | org.apache.jasper.JasperException: org.apache.jasper.JasperException: java.lang.ClassNotFoundException: org.apache.jsp._005fpage_jsp
INFO | jvm 1 | 2026/06/16 10:51:02 | at org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:546)

We use the /tmp/jetty-* directories for compiling JSPs. Sometimes, if the system is cleaning up /tmp, the app won't notice that and rebuild the JSP into a class file.

So if there is a service running that cleans up the /tmp directory, this can destroy the on-the-fly compilation of JSPs which is why you're seeing this issue.

 

Resolution

To fix this, either restart the server or just restart the Portal services as per:

TechDocs : DX NetOps CAPM 25.4 : Restart NetOps Portal

It may though happen again if you have a service/application running that cleans up the /tmp directory. If you do, then exclude the /tmp/jetty-* directories from the cleanup so it doesn't affect the system.
