Re: [tigerstripe-users] Velocity classloader error "java.lang.NoClassDef

[Eric Dillon <erdillon@xxxxxxxxx>]

Hi Kalyan,

I am afraid I don't know what is going on here. I am tempted however to
blame it on velocity :-).

I did google the exception and saw your post on some other forum. I saw a
note there about having multiple instances of the velocity-1.5.jar which is
not the case here.

Now, what are the symptoms of the error (beyond the log in the mail)? Does
your generation fail completely?

Eric
