Subject RE: Exception
Date Thu, 08 Feb 2007 20:58:25 GMT
You build your project using java 6 but trying to run it on a java 5 or
1.4 jvm - Sun's internal versions are different then the official
external version notation - 50.0 is java 6 while 49.0 is java 5.
You need to configure you Tomcat to use the newer JVM
