Hi All,

We have a webapp that was running under tomcat-5.5.26 - no problem

Recently we updated our webserver to tcServer which is actually a
Tomcat-6.0.20 pointing the content to original location under
tomcat-5.5.26 folder.

All is good.
Now I wanted to restore my setup back and run the same webapp under
original Tomcat-5.5.26

I'm getting all kinds of exceptions java.lang.NoSuchMethodError

I used qsh touch command to mark all the Tomcat-5.5.26 jar files so that
should trigger all original jars to be re-attached again.

Now compiler complains about java.lang.NoSuchMethodError: <init>

I understand that it is due to Java compatibility problem - but how do I
make sure that JVM loads all correct classes?

I do not think that merely touching the files cause the jars to be reattached. The simplest way to be certain is to use jar to zip the files together, delete everything, and unzip again with jar. If the error persists, then this is most likely your compiled JSP-classes giving problems. If so, then the easiest cure is probably touching all files.
