Confluence was not written to the specification of Java EE 1.5. Although implementing the methods will solve the compilation problems and possibly get Confluence to run, please take note that Confluence was not tested with Java EE 1.5.
A possible problem solution:
thanks to you i solved the problem 1
(download JDK 1.4, tomcat 4.x)
I solved problem 2, add (copy) all library files to the exploded directory!!
