[jboss-user] [Beginners Corner] - Re: org.apache.jasper.JasperException: Unable to compile cla

[alamandrax]

Hi jaikiran,

Thank you for the prompt reply. I did find the thread which dealt with modifying the $JBOSS_HOME\server\default\deploy\jbossweb-tomcat55.sar\conf\web.xml file and had made the modifications to check if it had any effect. I keep getting the same error again.

Is there anything else that I need to do? I did have some older Tomcat versions on my computer, but I have deleted them all. I've removed the CATALINA_HOME environment variable for the heck of it.

Apart from these, during the server startup, I get the following errors. I'm not sure if they're relevant but am including them here just in case.

I'm pasting the errors that I see in my browser here again (with the root cause this time)
