Re[4]: anybody has a tool to extract variable and class names out of Java Business and Java-Struts-ActionForm classes into xml, i.e. a free-marker usable data format?

.java file parsing? No. But one possibility is that you compile them to
classes with Sun's compiler ("javac" if you invoke it from command
line), and then use CGLIB to examine the resulting .class files. If the
compilation step is inconvenient, then maybe it is not that hard to
write a java program that extract these infos from a Java file... I
mean, it need not be a full-blown Java parser for that, so it is maybe
not that hard. A third possibility is to find a Java parser. I guess
there is Java language parser available for parser-generators as ANTLR
or JavaCC.
