Hi David, I'm back :)
I was mistaken about JAAS login. First JAAS login succeeds in a usual
way. Then JNDI lookup() is performed and it fails.
Trace info: class org.openejb.client.Client, method request(),
conn = ConnectionManager.getConnection( server ); - OK
out = conn.getOuputStream(); - OK
PROTOCOL_VERSION.writeExternal(out); - OK
out.write( req.getRequestType() ); - OK
objectOut = new ObjectOutputStream( out ); - FAILS
with IOException("Broken pipe");
Hoping for new guidelines from you,
Oleg

More info: client request reaches server, server (during JNDI lookup)
performs JAAS login (I have configured my own LoginModule, but of course
something can be wrong there), login succeeds. I don't know what happens
then. I guess some unexpected exception happens there, and it isn't
transferred to client correctly, but leads to "unexpected EOF"-like error.
Okay, David, thank you again, conversation with you was really helpful,
it cleared the picture for me, so I think for now I will better stop
taking more of you time and continue my investigation and experiments.
I'll be back ;)

No, this is not the case. Client and server take jars from the same
place, and both use OpenEJB 2.1.1 which comes with Geronimo 1.1.1.
Thanks for you time,
Oleg

The first thing that comes to mind is that perhaps you are trying to
use incompatible openejb client and server jars? IIUC geronimo 1.1.1
needs openejb2 client jars and geronimo 2 needs openejb3 client jars
and they are not interoperable. However I am not the most expert on
this subject. Knowing exactly which openejb jar versions are in your
client classpath would definitely be helpful though.
thanks

Thank you for your answer, David. You are right, I already had
EJBNetworkService and have installed the second one. The idea to do
this came to me when I got the following exception during JNDI
lookup of my bean from standalone client app:
Cannot deternmine server protocol version: Received null/0.0; nested
exception is:
java.io.IOException: Unable to read protocol version.
Reached the end of the stream.

Then I found this message
http://mail-archives.apache.org/mod_mbox/geronimo-user/200512.mbox/[EMAIL PROTECTED]
but didn't understand where to put "allowHosts" and decided to add a
new EJBNetworkService for that :-/
Okay, now I've got it: I've added
<attribute name="allowHosts">0.0.0.0</attribute>
to EJBNetworkService gbean in config.xml, now it looks this way:
<module name="geronimo/openejb/1.1.1/car">
<gbean name="EJBNetworkService">
<attribute name="host">0.0.0.0</attribute>
<attribute name="port">4201</attribute>
<attribute name="allowHosts">0.0.0.0</attribute>
</gbean>
</module>
But nothing changes, I get the same exception during lookup().
Please, advise me the next step.
Thank you for your help,
Oleg

I don't understand what you are saying about needing to deploy the
EJBNetworkService... I can see needing to change the port or host
but there's one already started out of the box.
Your error is caused by having 2 classloaders that load the openejb
classes independently. There should be only one such classloader
per jvm, the one from the openejb config (module). Can you figure
out what the other one is? If you really need another listener you
should be sure that the openejb configuration (car) is a parent
(dependency) of the configuration you put it in. Openejb is
extremely unlikely to work if you have more than one ContainerIndex
running since most references to it are through a static variable.
hope this helps

Hello all,
First I have successfully deployed my EJB, but couldn't connect to
it from standalone application. Then I found that I also need to
deploy EJBNetworkService/EJBServer stuff. Okay, did that and got
java.lang.ClassCastException: org.openejb.GenericEJBContainer

org.openejb.ContainerIndex.doStart(ContainerIndex.java:123)
Then I undeployed my EJB and successfully deployed
EJBNetworkService. Now deployment of the EJB causes the same error.
I've found such error in the mail archives:
http://mail-archives.apache.org/mod_mbox/geronimo-user/200605.mbox/[EMAIL PROTECTED]
but that message left unanswered.
Did anyone have such problems?
Any guidelines for me on what to do next?
Thanks in advance,
Oleg
P.S. Geronimo 1.1.1 (actually, WAS CE)
