Hi everybody,
I need to use Apache xerces in my plugin. I don't know how to "add" this
library so that my plugin works.
I get a "SAX2 driver class org.apache.xerces.parsers.SAXParser not found".
I read in one article that I have to create a separate plug-in to
contain the library and make my first plugin depend on this new one.
BUT, According to that article there should already be avalaible
dependencies for Xerces or ant...But I don't get it in the dependencies
list....
here is the article

Am I missing something ??

Hi
Step 4 is not missing - it's just a typo.
I don't know SAX2, but might it be that it is distributed in several jar
files. If it is, you must add all of them to your plugin.
Another reason could be: you need to copy the jar into the project in
order to succeed in step 5. If you add the dependency (step 3) to
"external jars", you cannot include it in step 5.
Hope this helps

Hello.
I posted another article
( http://www.eclipse.org/newsportal/article.php?id=43695&g roup=eclipse.platform#43695)
where I described a situation with the same problem...
I tried to follow your steps to create a "library plug-in" but it still
does not work.
I found an old bug report
( https://bugs.eclipse.org/bugs/long_list.cgi?buglist=36643#c2) where this
problem is discussed and aparently the bug was resolved. The strange thing
is that I still have this problem (using Eclipse 3.0.1) and in the report
is mentioned that jdom doesn't work due to this problem... but I'm using
it to in my plug-in and it works. Only xerces won't work.
Can You help me?
Thanks,
Marco

Hi everybody.
I solved the problem by adding the following line:
Thread.currentThread().setContextClassLoader(this.getClass() .getClassLoader());
just before calling the method where Xerces is used.
Greetings!
