Hi there.
I have some jar files with no servlet, no EJB classes, just java
classes and one xml descriptor. My central
servlet loads some file://somewhere/configuration.xml which points to
these jar files and uses own classloader (i did not write it) to load
classes in these jars.
now I do something like 'touch application.war' to force reloading of
my application. It works. I modify configuration.xml mentioned above
and changes apply as expected -- aplication was restarted and re-reads
its config.
What doesn't work is .jar access. When I modify sources and rebuild
.jar file, restart application by 'touch ...',
application fails to access .jar file with different errors.
When I just restart jboss, everything's OK...
I suppose this is something with classloader/caches/open files or similar...
Would someone experienced enlighten me ?
I'd like to know where to start looking for a problem. Can it be
solved or it is the way JVM or jBoss works?
Please help. Thank you.
Example of exceptions:
org.xml.sax.SAXParseException:
File "jar:file:///path/SimpleFormStep1.jar!/qb.xml not found
-- but it's there !
*XML fatal error at: jar:file:///path/SimpleFormStep1.jar!/qb.xml:1
*XML fatal error: The markup in the document preceding the root
element must be well-formed.
-- but I did not changed anything
-- and when i just changed three letters in string, rebuilt jar
and invoked re-deployment:
