Hi,
As subject says, I have been experiencing problems
with JNDI lookups from the client for the last month
or so. (Now you all know why I haven't committed
anything lately.)
The problem has changed over time, but one thing is
common:
It always seems to happen when a JNDI lookup of a
home interface is done. In particular it seems to
always be in a call to MarshalledObject.get() in
org/jnp/interfaces/NamingContext.java line 299.
The problem seems to surface as one of the following:
- An exception thrown on attempt to get the superclass
of the home proxy. Ie. ClassNotFoundException on
org.jboss.ejb.plugins.jrmp13.interfaces.HomeProxy.
org/jnp/interfaces/NamingContext.java line 299 is
in the stack trace.
- The client hangs.
The call to MarshalledObject.get() in
org/jnp/interfaces/NamingContext.java line 299 goes
in, but control never comes back.
For the last week or two, I have only seen client hangs
and no exceptions.
Changing conf/default/jboss.properties sometimes helps
a little, but never makes the problem go completely
away. In particular changing the java.rmi.codebase
property seems to have an effect: If I set it to
http://localhost:8083/ it sometimes helps a little.
If I set it to http://myhost.mydomain.dk:8083/ it
sometimes helps a little more.
But no matter what I do I am unable to run all the
jbosstest tests.
When debugging, I am always stopped by some native
method that I cannot step into to find out about the
problem.
I use Suns JDK1.3 for Linux on a RedHat 6.1 host.
I have (without success) tried:
- Two older JDK1.3 betas/prereleases from Sun.
- Lots of CVS downloads. The problem seems to
be changing a little from time to time, but
for the last month it has been there constantly
one way or another.
- Taking a new machine, installing another (Suse)
Linux distribution, downloading Suns JDK1.3 (again,
to make sure no transmission error), downloading
jBoss, setting it all up again on completely new
machine. Same problem.
With success I have tried an old CVS snapshot from
the middle of last month. So whatever has happened
probably happened during the last half of last month.
I am basically at a dead end here. I really would
like to use jBoss, but unless I get this fixed I am
forced to use another product instead.
Please help!!
I have been spending a lot of time on this, and I do
not mind spending a lot more time if needed to get
this fixed.
But I simply do not know what to do about it!
Best Regards,
Ole Husgaard.
