Hi,

when I try to emerge xalan-2.6.0 I get the following error

I solved similar problems to your first error as follows:

I know it's ugly and time consuming, but so far it works.

The source/target problem can be solved by this. Unfortunately it still does not work.

No sorry.

The errors that you are getting seem rather odd to me. I can't really see how the 1.5 compiler is to blame for them. If the output is correct, then they probably should not compile on any JDK version.

The errors reflect, that the w3c dom implementation changed in java 1.5.
For example Node does not have a method "getUserData" in java 1.4
(http://java.sun.com/j2se/1.4.2/docs/api/org/w3c/dom/Node.html)
which was introduced in 1.5
(http://java.sun.com/j2se/1.5.0/docs/api/org/w3c/dom/Node.html).

Fixing errors in xalan proofed fruitless as expected.

The reinstallation of "everything java" worked quite nicely with

I need an eclipse plugin that will ONLY work on java 1.5
Do you people suppose I will run into problems considering eclipse will want ant which can only work on a 1.4.2 installed system (as shown above) ?

(the german topic I found says to install eclipse on 1.4.2 and then point eclipse to 1.5 to use that one, but I only figured it from guessing half the german words so any reply is still welcome...)

I can't really say for sure, because I am using a not-emerged version directly from eclipse.org (from an old installation). I am also not sure how the ant issue is connected to this, because eclipse uses its own (plugined) version of ant.
However, I guess that the eclipse-project people also compile with a 1.4 java and it runs on my system when pointed to 1.5.

To make sure, perhaps you could give a link to the german thread you have found. I happen to be german. :wink:

Great, that might help

I think you understood it pretty well. Did you learn german in school or did you figure with dutch-german similarities?

To summarise it, this guy had the same problem with xalan (when emergeing eclipse) I had (when emerging the xalan ebuild). They agreed it is the java 1.5 to java 1.4 incompatability.
The solution was, as you expected, to set java to 1.4 with java-config, set it up again after the installation and point eclipse to java 1.5 afterwards.

Yea that worked like a charm, thanks. I still get some errors on annotations in the editor though, but not really in a consistent matter. Guess the next eclipse version will fix this.

PS I just figured dutch-german similarities as I never learned any german

I'm having the same problem, but when I set java-config back to a 1.4 jdk and try to compile xalan I get this error:

Implication · n00b Joined: 07 Mar 2005 Posts: 14

Well that's exactly the same problem I encountered (and described above).

The only solution I have seen for this is to uninstall and recompile all java related programms. But that is described above, right?

shredz · Posted: Fri Mar 11, 2005 3:21 pm Post subject:

Yes, setting java back to 1.4 and not recompiling previous builds won't work. The solution above kinda overdoes it by remerging EVERYTHING java... which includes the jdk's themselves for instance.

Ok, thanks for the clarification.

Implication would you mind posting the bash script you used to recompile everything java? (if you still have it)

Thanks

Implication · n00b Joined: 07 Mar 2005 Posts: 14

Ups, I forgot to mention to ignore the jdks. Would not make sense to re-emerge those, of course.
I'll see if I can find the script when I am home.

Implication · n00b Joined: 07 Mar 2005 Posts: 14

I could not find the original script I used, but the following should work.
:!:

However, definitely make a backup-list of the installed packages before executing the script. Otherwise if an installation step fails, all java packages will be removed and you wont know which to install anymore (except for some emerge log-files which probably would tell, but I don't know about that stuff).

So I would recommend that you save the list of packages like that.

Thanks!

Probably adding --oneshot to the emerge line would be recommended as well. No need to put all of them in your world file.

Thanks again.
