I was on JVM 1.5 now have reverted back to 1.4.2.. now my Tomcat won't
run.. (I did change JAVA_HOME to C:\j2sdk1.4.2_09 (& of course path to
C:\j2sdk1.4.2_09\bin;) don't know what other settings to change

can compile fine, but apps won't run, and get this error when try to run
Tomcat's home page..
javax.servlet.ServletException: org/apache/jsp/index_jsp (Unsupported
major.minor version 49.0)
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:244)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)

thank you..

Tomcat version is 5.0.27... when I first installed it it ran fine on
1.4.2.. then upgraded to 1.5, now reverted back to 1.4.2.. so I don't
see why same Tomcat shouldn't run w/1.4.2.. thank you.. Frances

You'll need to delete the 'work' directory for any webapps - Jasper will
have compiled your JSPs using the 1.5 compiler, so they won't be backward
compatible. I think it's literally called $CATALINA_HOME/work - just empty
it, Tomcat should recreate it.

Now you mention it that probably applies to the previous topic about this
too...

thank you very much.. I did know about emptying out 'work' directory
(and have it before when I wanted to make sure JPS's are being
recompiled anew) however in this case it was even Tomcat home page
(http://localhost) that wouldn't run, which is why I was a bit puzzled..
so: deleted all stuff inside here..

C:\tomcat\work\Catalina\localhost

wasn't sure whether also to delete 'Catalina' dir.. but deleting
everything inside 'localhost' did it.. will have to recompile all my
servlets again, but that's fine... again, many thanks!! :)
