I've got an issue where InitialContext#lookup will hang forever doing a lookup if there is a problem with the network. I appreciate this is the default settings of the TCP sockets to wait forever, so I've tried to configure the timeout using 'jnp.timeout' and 'jnp.sotimeout', but it still waits forever.
Hashtable<String, String> env = new Hashtable<String, String>();
env.put("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
env.put("java.naming.provider.url", "jnp://10.9.1.11:1099");
env.put("java.naming.factory.url.pkgs", "org.jboss.naming");
env.put("jnp.socketFactor", "org.jnp.interfaces.TimedSocketFactory");
env.put("jnp.timeout", "1000");
env.put("jnp.sotimeout", "1000");
InitialContext ctx = new InitialContext(env);
HelloWorld world = (HelloWorld) ctx.lookup("HelloWorldBean/remote");
world.sayHello("hello");
// disconnect network here
world = (HelloWorld) ctx.lookup("HelloWorldBean/remote");
world.sayHello("hello");
In the above example if the network is disconnected before the first lookup it times out as expected, but if the network is disconnected between the first and the second lookup it doesn't timeout at all (waited 10 min+).

hi all
i am new to jbpm.
i am trying to implement some web services based on jbpm. i have implemented my services and test it in stand alone mode and it is ok!
but when i am trying to deploy my services on weblogic server it is thrown by some exceptions!
*org.hibernate.HibernateException: Errors in named queries: findTasks, findMessages, findTimers, findGroupsByUserAndGroupType, findProcessInstanceIds, findJo

Truncated. see log file for complete stacktrace*
after searching the internet i have found that adding
*<property name="hibernate.query.factory_class">org.hibernate.hql.classic.ClassicQueryTranslatorFactory</property>*
to hibernate config fix the problem. i have tried the solution and it was successful, but after deploying
when i want to run one of my services it throws another exception
my code snippet is:
*ProcessInstance processInstance = executionService
.startProcessInstanceByKey(processDefinitionId, parameters,
userId + "-" + sequence);*
and the exception is :
*Error invoking com.pardis.notification.core.Services (POJO): org.hibernate.QueryException<ComponentHandler.handleRequest:144>

Hi Ron,
I am observing similar issue in my application. We are using Jboss 4.2.0.GA, Jboss Remoting 2.5.3.SP1
We have a firewall between our server and client and we followed the forum,
http://blog.akquinet.de/2009/09/30/using-jboss-messaging-in-a-firewalled-... http://blog.akquinet.de/2009/09/30/using-jboss-messaging-in-a-firewalled-...
to set our parameters like below,
+ <attribute name="marshaller" isParam="true">org.jboss.jms.wireformat.JMSWireFormat</attribute>+
+ <attribute name="unmarshaller" isParam="true">org.jboss.jms.wireformat.JMSWireFormat</attribute>+
+ <attribute name="dataType" isParam="true">jms</attribute>+
+ <attribute name="socket.check_connection" isParam="true">true</attribute> +
+ <attribute name="serverBindAddress">${jboss.bind.address}</attribute>+
+ <attribute name="serverBindPort">4457</attribute>+
+ <attribute name="clientSocketClass" isParam="true">org.jboss.jms.client.remoting.ClientSocketWrapper</attribute>+
+ <attribute name="serverSocketClass">org.jboss.jms.server.remoting.ServerSocketWrapper</attribute>+
+ <attribute name="numberOfCallRetries" isParam="true">5</attribute>+
+ <attribute name="pingFrequency" isParam="true">5000</attribute>+
+ <attribute name="pingWindowFactor" isParam="true">2</attribute>+
+ <attribute name="onewayThreadPool">org.jboss.jms.server.remoting.DirectThreadPool</attribute> +
+ <attribute name="stopLeaseOnFailure" isParam="true">true</attribute>+
+ <attribute name="clientLeasePeriod" isParam="true">10000</attribute>+
+ <attribute name="validatorPingPeriod" isParam="true">10000</attribute>+
+ <attribute name="validatorPingTimeout" isParam="true">5000</attribute>+
+ <attribute name="failureDisconnectTimeout" isParam="true">0</attribute>+
+ <attribute name="callbackErrorsAllowed">1</attribute>+
+ <attribute name="registerCallbackListener">false</attribute>+
+ <attribute name="useClientConnectionIdentity" isParam="true">true</attribute>+
+ <attribute name="timeout" isParam="true">1800000</attribute>+
+ <attribute name="numberOfRetries" isParam="true">10</attribute>+
+ <attribute name="JBM_clientMaxPoolSize" isParam="true">200</attribute>+
+ <attribute name="callbackTimeout">10000</attribute>+
+ <attribute name="secondaryBindPort">4481</attribute>+
With this implementation, we have mulitple Connections in CLOSE_WAIT state most of them getting cleared and some left behind.
After several days, we loose the JMS communication. We need to restart the application again to get rid off.
Also we observed the below exception multiple times when the issue happens,
Exception:
2011-03-28 11:50:10,271 TRACE [org.jboss.remoting.transport.socket.ServerThread(638)](WorkerThread#4[10.255.254.134:42933]) WorkerThread#4[10.255.254.134:42933] EOFException received. This is likely due to client finishing communication.
java.io.EOFException

at org.jboss.remoting.transport.socket.ServerThread.dorun(ServerThread.java:586)
at org.jboss.remoting.transport.socket.ServerThread.run(ServerThread.java:234)
Kindly share some light to resolve this.
Regards,
Joseph.
