Subject Re: NoClassDefFoundError - Weblogic 6.1

I noticed something very strange in WL 6.1 SP2 -- it will not load jars that
have more than one dot in the name. I had to change our
jakarta-regexp-1.2.jar to jakarta-regexp-1_2.jar (got rid of the . in 1.2)
to get it to load correctly. If your struts jar is called struts-1.1.jar or
something like that, it might not load correctly.
