Pete's Blog

It was nice to meet you last week Peter and thanks again for your talk -- good stuff. I look forward to applying some of these improvements to our environment.

Hey Peter-

Thanks for the interesting talk. I tried adding xalan.jar (and serializer.jar, xml-apis.jar and xercesImpl.jar) to my jre lib/endorsed directory. Now, when I try to compile I get the error below. Any ideas?

Interestingly, I just fixed this problem. I had copied the jars to both /lib/endorsed and /jre/lib/endorsed. When I deleted the endorsed under jre, the problem went away. I hope this helps somebody in the future.
