| [jetty-users] help plug-in issue |

Hi guys I am using org.eclipse.help in my RCP. And I have come
across a strange issue: Sometimes when I go to Help->Help Contents, I get a
window with this: HTTP ERROR 500 Problem accessing /help/advanced/help.jsp. Reason: Unable to compile class for JSP Caused by: org.apache.jasper.JasperException: Unable to compile class for JSP at

refresh or restart the program, the error will not appear. It seems someone has the same problem: http://www.eclipse.org/forums/index.php/m/624477/#msg_624477 But no one solve this. So, Is there anyone who can help me? Any ideas how to fix
this? Thanks! --Cesar |
