Well, your error log shows the problem. Basically, you have a mismatch between the version of Java you compiled with (1.5) and the one you're trying to run with (probably 1.4.2). Make sure your java executable in Xcode points to /usr/bin/java.


BTW, this is a very common problem. Searching Google for "Unsupported major.minor 49.0" would have led to numerous helpful sites.
