Hi Vasily,
In the j2ee-server-plan.xml file it configures the IP addresses that the
(OpenEJB) EJB daemon will accept connections from in the "allowHosts"
attribute. For example:
<!-- EJB Protocol -->
<gbean gbeanName="geronimo:type=NetworkService,name=EJB"
class="org.activeio.xnet.StandardServiceStackGBean">
<attribute name="name">EJB</attribute>
<attribute name="port">${PlanOpenEJBPort}</attribute>
<attribute name="host">${PlanServerHostname}</attribute>
<attribute name="allowHosts">${PlanClientAddresses}</attribute>
<attribute name="logOnSuccess">HOST,NAME,THREADID,USERID</attribute>
<attribute name="logOnFailure">HOST,NAME</attribute>
<reference
name="Executor"><name>DefaultThreadPool</name></reference>
<reference
name="Server"><gbean-name>openejb:type=Server,name=EJB</gbean-name></reference>
</gbean>
The In the geronimo\var\config.xml file (where you can specify attribute
values that can override the values in the deployed plan) you should see
the following section:
<configuration name="org/apache/geronimo/Server">
<gbean name="openejb:type=NetworkService,name=EJB">
<attribute name="host">0.0.0.0</attribute>
<attribute name="port">4201</attribute>
</gbean>
</configuration>
In theory, you should be able to edit the config.xml file and specify
the allowable remote host by doing something like:
<configuration name="org/apache/geronimo/Server">
<gbean name="openejb:type=NetworkService,name=EJB">
<attribute name="host">0.0.0.0</attribute>
<attribute name="port">4201</attribute>
<attribute name="allowHosts">myhostname</attribute>
</gbean>
</configuration>
*** But I have a bug currently open where the port number in the
config.xml file as shown in the example above is not actually used and I
have a feeling the same problem will happen for allowHosts (see
http://issues.apache.org/jira/browse/GERONIMO-1151 ). I haven't had a
chance to debug this yet. Let me know what happens.
I think most of the testing so far has been done on the localhost with
the default port.

John

Hello, all.
I'm trying to run an application that should access the beans
(deployed in a Geronimo server running on other machine) with a JNDI
request.
However, I get the following exception immediately at "new
InitialContext()" statement:
javax.naming.AuthenticationException: 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.
The Geronimo console states the following at that moment:
15:31:20,132 ERROR [EJB] Host <app-host> is not authorized to access
this service.
java.lang.SecurityException: Host <app-host> is not authorized to
access this service.

(here <app-host> replaces the IP address of the machine where I run my
application)
I'm using a default installation of Geronimo 1.0 M5, and Windows XP
SP2 and Sun's JRE 1.4.2_08 on both machines.
The client application's system properties include:
java.naming.factory.initial=org.openejb.client.RemoteInitialContextFactory
java.naming.provider.url=<geronimo-host>:4201
java.naming.security.principal=system
java.naming.security.credentials=manager
(here <geronimo-host> replaces the name of the machine where Geronimo
is running and principal/credentials are the same I use to login to
Geronimo console)
Also, I've put a local copy of openejb-core-2.0-G1M5.jar to the
application's classpath for context factory to be found.
Could somebody please point me at what I'm doing wrong and how can I
tune Geronimo to accept JNDI connections from the remote machine?
Thanks in advance,
