Hi.
I have been getting the 'unable to compile class for JSP' because 'package
org.apache.jasper.runtime does not exist'. I found jasper-runtime.jar, which contains
the package org.apache.jasper.runtime in:
.../jboss-4.0.0RC1/server/marketingcalendar/deploy/jbossweb-tomcat50.sar/
My app, marketingcalendar, is hosted on a Sun Solaris platform using JBoss 4.0.0,
Sun's java 1.4.2, Struts, Spring, and Hibernate. I don't know what is triggering
this error. It happens on least used and most used pages but not all at once. Pages that
have been working for several days may suddenly come up with this error message.
Restarting the server clears the problem. The error has come up with in a day of
re-starting the server. Sometimes, the error pops up several days/weeks later after the
page has been working for a while.
When there is a jsp/java changes, I shut down the JBoss server, move in the modified
jsp/class files, and then re-start the server. The jsp compilation should happen only
once when a user brings up the specific page. So, I don't understand pages that were
displaying fine for days would suddenly get this 'unable to compile class for JSP'
error.
In the .../jbossweb-tomcat50.sar/web.xml, I changed the value of the fork parameter to two
weeks ago. That didn't fix the problem. The rest of the web.xml has the default
values.
Any ideas on how to fix this error?
The following is a shortened version of the error users see when this problem occurs. I
have set in bold the portions of the message that remains the same.
