Re: Tomcat 5.5.9 - When JSPs change, gives error org.apache.xerces.jaxp.SAXParserFactoryImpl could not be instantiated
Got mod_jk running; that's not the issue. Another curious piece to this anomaly is that making a change and then restarting server does not head off the error. I have to make the change, access the page (thus generating the error) THEN restart the server and access the page again, at which point the error is corrected. If I change more than one page, I have to access one page, restart the server, access the second page, restart the server again, etc. Why should accessing the page and throwing the error make any difference? Why does restarting the server not help unless the error is thrown first? Can anybody help me with this? It's driving me nuts!
