Re: Struts Installation Problem (duplicate servlet.jar)

[Wayne Ohm <wo...@home.com>]

I thought there might be some people who are having the same problem, so I'm
sharing this with you.    The NoSuchMethodError problem was caused indeed by a
duplicate servlet.jar being in C:\jdk1.3\jre\lib\ext (probably an old version?).
Perhaps this should be mentioned in the next README.

The most likely explanation is that you have an extra copy of struts.jar or
servlet.jar on your classpath (or in the system extensions directory,
$JAVA_HOME/jre/lib/ext).  Could you double check that?
