Errors at building classpath, info attached (Real One)

[Marcos Roriz <marcosrorizinf@xxxxxxxxx>]

Sorry for the last post, I hit enter unintentionally.
Guys, I tried building yersteday classpath cvs and after some problems I
 got it to work :)
I'll concern those and the eclipse problems in this mail. 

First I'll tell what I had to do to get eclipse to get out of the red state in errors. I copied these two files (which 
the wiki refers) to .java:

• classpath/gnu/classpath/Configuration.java.in
• classpath/gnu/java/security/Configuration.java.in

Because
 the build uses the .in to configure, don' t move them (yes I did that 
:'[). Also add the jaxme jar (usually on /usr/share/java) to the build path (I
 thought that I needed antlr, am I missing something here?) and we go 
down to two errors I think, which are basically incompatibility with my version of jaxme.

About the build problems:
Here's
 the first problem, it complains about the following errors (Error 1) which can be
 fixed with Giuseppe Scrivano patch.  I wonder why the thread isn't showing on classpath-patch mailing list.

The second error is about building the web plugin. It seems that on ubuntu the mozilla headers are separated on two folders stable and unstable. The build only get the stable directory. So here we can upgrade to a newer version (which only have one directory) or compile our own xulrunner. I did an upgrade to a newer version (got lucid version), the error went away.

I wonder if I can add this info on the wiki. What you guys think?
