Package: tomcat6<br>Version: 6.0.20-5 <br>Folks,<br><br> Tomcat6 is failing to find some classes for us in valid WAR files on Squeeze. This has been extensively tested<br>and works beautifully for us on older revisions of java/tomcat6 (squeeze) packages back installed on Lenny<br>
and on the current tomcat6 on Ubuntu. <br><br>Potentially useful problem information:<br> <br>I have also run this with both the openjdk and sun java 6, so it's Tomcat's problem with a very high likelihood. <br><br>
I have compiled our JARs with sun 1.5 sun 6 and openjdk, it does not matter which. <br><br> I have all three installed (as I actually need this in dev/production) but this also occurs with<br>just the openjdk.<br><br> Running Jar files have been copied from UBUNTU to Debian to demonstrate that this is really a debian not a build<br>
problem.<br><br> And of course, it's CRITICAL.<br><br> I have multiple javas installed (due to some packages requiring 1.5 and <br><br>You'll see traces like (but I can not provide the jar, sorry):<br><h1>HTTP Status 500 - </h1>
