There's a problem in 0.9.0 with transactions, where a
ejb method called by another ejb method will not get
the same jdbc connection as the caller. And because in
a chain of ejb method calls, the top of the ejb chain
performs the actual close of the db connection, this
jdbc connection will be left dangling.
To fix this problem, copy the file (attached)
MethodDescriptor.java file into
src/org/lateralnz/wicker/deploy and rebuild.
