Re: [jnc-users] Null PointerExceptionatjava.net.URLClassLoader.getPermissions

Hi Marco,

I think I may be making "some" progress and I have a feeling this may be the 
thread you are talking about:
http://sourceforge.net/mailarchive/forum.php?thread_name=46E7A0BF.2060301%40gmx.ch&forum_name=javacompiler-users

More specifically I'm guessing this part of the thread is what could well be 
relevant:

"lets just try to manually include all xml objects into the binary:

1. create a temporary folder. e.g. d:\test
2. open "cmd" and change into that folder
3. extract all objects from libgcj.a (run in cmd):
path_to\gcc-122233-win\bin\ar.exe x path_to\gcc-122233-win\lib\libgcj.a
4. Delete all extracted files that have no "xml" in the name (you know how 
to do that automatically, right?)
5. Now remove the two files I sent you before and instead, in step 3 in the 
GUI, add the directory: d:\test\*

With this procedure, you've the complete XML support in your binary. If 
everything works, you might want to try to remove some of the objects (if 
the application still works without them, they're not needed)..."

Now, no matter what I do it doesn't seem to increase the size of the binary 
(and I get the same error), so I'm guessing I'm doing something wrong to get 
them added.

I performed steps 1, 2 and 3 no problem. I skipped step 4 for now.

I've tried step 5 although as I say it didn't increase the size of the 
binary so I'm assuming nothing extra made it into the binary.

One thing I did notice is that your instructions suggest adding the 
directory "d:\test\*" however, adding \* seems to be impossible using your 
GUI as the directory browsing dialog simply removes it. If it navigate to 
the said directory using the dialog and then manually add the \* (or /*) it 
simply get's removed.

Another interesting note is that, if I add the options as custom GCJ options 
like; org.xml.sax.driver.o it simply fails with cannot find file. But if I 
add the option as c:\temp\templib\org.xml.sax.driver.o it doesn't complain 
but nothing seems to be added to the binary.

I feel I'm really close but either something is wrong or I'm missing 
something fundamental.

I'm using your latest GUI with GCC downloaded from your site.

Here's the GUI settings that may be relevant:

Step 1
Files: None
Directories: c:\temp\templib
Archives: filesquirrel.jar, flaresdk.jar, smtp.jar, dsn.jar, 
log4j-1.2.13.jar, dom4j-1.6.1.jar, commons-io.1.2.jar, mailapi.jar, 
pop3.jar, imap.jar. (All with checkbox ticked for complete compilation).

Step 2
Main class: com.flare.applications.FileSquirrel.App
java.library.path: None
Use CNI: Ticked
Omit stripping, omit packing, disable optimization all not ticked

Step 3
Custom GCJ Flags
C:\temp\templib\javax.xml.parsers.DocumentBuilderFactory.o
C:\temp\templib\javax.xml.parsers.SAXParserFactory.o
C:\temp\templib\javax.xml.parsers.TransformerFactory.o
C:\temp\templib\org.relaxng.datatype.DatatypeLibraryFactory.o
C:\temp\templib\org.xml.sax.driver.o
-findirect-dispatch

Exclude GUI, Exclude JCE, Add GNU regex all ticked

Compilation and packing executes just fine, however I still get the Caused 
by: java.lang.ClassNotFoundException: org.xml.sax.EntityResolver not found 
exception.

Obviously I'm still fighting it, but any pointers would be greatly 
appreciated.
