Well, it is somehow not in the classpath.  The JVM isn't lying when it
says that class isn't available, and Velocity 1.6.3 needs it.   Are
you perhaps using the velocity-1.4-dep.jar and then switching to
velocity-1.6.3.jar?  If so, you might try the velocity-1.6.3-dep.jar.

We are not using any velocity-dep jars at all.

Are you sure you have Commons Lang 2.1+?


Yes:

# rpm -q jakarta-commons-lang
jakarta-commons-lang-2.4-1.fc13.x86_64

Hi.

We have a tomcat 5.5 java application which has been successfully using
velocity 1.4 for a number of years (most recently on Fedora 12).

When we attempted to run this application on Fedora 13 Beta (which uses
velocity 1.6.3), we receive the following stack dump:

We have verified that the jakarta-common-lang jar file exists and is
readable from /usr/share/java, and when we downgraded velocity 1.6.3 to
1.4,
the application began running successfully.

Has anyone else encountered this or a similar issue?

The application needs to continue to support velocity 1.4 --- are there
migration guidelines for this sort of issue that will allow the
application
to continue to work with velocity 1.4, but also work with velocity 1.6?

Thanks in advance,
-- Matt
