I have a message driven bean that is being invoked from data received on a TCP socket via a JCA Resource Adapter in a GlassFish 3.1.1 application server. The deployment descriptor in the sun-ejb-jar.xml file, specifies the URL and port of the socket. When the MDB is deployed, I see the app server execute the endpointActivation() method in the resource adapter with the MessageEndpointFactory and ActivationSpec as parameters.
This works fine when the URL and port are known before deployment and can be specified in the XML file, but now I need the ability to change the TCP socket during runtime in my EJB code. I couldn't find any references in the JCA spec about how to do this during runtime.
For reference, I downloaded the specification from Oracle's website.
J2EE Connector Architecture Specification Version 1.5
Basically, I'd like to move the following XML code that populates the ActivationSpec into my EJB code.
<sun-ejb-jar>
<enterprise-beans>
<ejb>
<ejb-name>MyInboundSocketMDB</ejb-name>
<mdb-resource-adapter>
<resource-adapter-mid>jca-sockets-rar</resource-adapter-mid>
<activation-config>
<activation-config-property>
<activation-config-property-name>url</activation-config-property-name>
<activation-config-property-value>localhost</activation-config-property-value>
</activation-config-property>
<activation-config-property>
<activation-config-property-name>port</activation-config-property-name>
<activation-config-property-value>5006</activation-config-property-value>
</activation-config-property>
</activation-config>
</mdb-resource-adapter>
</ejb>
</enterprise-beans>
</sun-ejb-jar>
Thanks for any suggestions.
You can change your activation-config-property-value in the glassfish web admin.

We are creating a Mule application which will be running in a container on Kubernetes and will be in a replica set that will be connecting to JMS 2.0 Red Hat AMQ 7 (based on ActiveMQ Artemis).
The pom.xml has been configured to get the jms client:
<dependency>
<groupId>org.apache.activemq</groupId>
<artifactId>artemis-jms-client-all</artifactId>
<version>2.10.1</version>
</dependency>
And the JMS config is configured as:
<jms:config name="JMS_Config" doc:name="JMS Config" doc:id="8621b07d-b203-463e-bbbe-76eb03741a61" >
<jms:generic-connection specification="JMS_2_0" username="${mq.user}" password="${mq.password}" clientId="${mq.client.id}">
<reconnection >
<reconnect-forever frequency="${mq.reconnection.frequency}" />
</reconnection>
<jms:connection-factory >
<jms:jndi-connection-factory connectionFactoryJndiName="ConnectionFactory" >
<jms:name-resolver-builder jndiInitialContextFactory="org.apache.activemq.artemis.jndi.ActiveMQInitialContextFactory" jndiProviderUrl="${mq.brokerurl}"/>
</jms:jndi-connection-factory>
</jms:connection-factory>
</jms:generic-connection>
<jms:consumer-config>
<jms:consumer-type >
<jms:topic-consumer shared="true" durable="true"/>
</jms:consumer-type>
</jms:consumer-config>
<jms:producer-config persistentDelivery="true"/>
</jms:config>
Then in the JMS listener component:
<jms:listener doc:name="EMS JMS Listener" doc:id="318b4f08-daf6-41f4-944b-3ec1420d5c12" config-ref="JMS_Config" destination="${mq.incoming.queue}" ackMode="AUTO" >
<jms:consumer-type >
<jms:topic-consumer shared="true" subscriptionName="${mq.sub.name}" durable="true"/>
</jms:consumer-type>
<jms:response sendCorrelationId="ALWAYS" />
</jms:listener>
The variables are set as:
mq.client.id=client-id-135a9514-d4d5-4f52-b01c-f6ca34a76b40
mq.sub.name=my-sub
mq.incoming.queue=my-queue
Is this the best way to configure the client? As we have seen errors in the logs when deployed to K8s regarding connections to the AMQ server:
javax.jms.InvalidClientIDException: client-id-135a9514-d4d5-4f52-b01c-f6ca34a76b40 was already set into another connection
In JMS 2.0 you don't have to set the client identifier when creating a shared durable subscription. However, if you do set the client identifier then it must be unique per connection. For whatever reason (e.g. due to Mule or perhaps K8s) multiple connections are being created and since each connection is using the same client identifier you're receiving the javax.jms.InvalidClientIDException.
Remove clientId="${mq.client.id}" from your configuration and the javax.jms.InvalidClientIDException should go away.
We are trying to migrate from IBM WAS to Wildfly server.
Below is my ibm-ejb-jar-bnd.xmi file. Where should this binding content be added in Wildfly for listener ports to be active again.
<ejbbnd:EJBJarBinding xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI" xmlns:ejb="ejb.xmi"

</ejbbnd:EJBJarBinding>
We changed the binding as well in the standalone XML along with changes to the MQ listener jars.
Dears,
I'm trying to call ejb3 in jboss 5.0.1 from Wildfly 10 or EAP 7.
My code:
final Properties env = new Properties();
env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
env.put("java.naming.factory.url.pkgs", "org.jboss.ejb.client.naming");
env.put(Context.PROVIDER_URL, "remoting://localhost:1099");
env.put("org.jboss.ejb.client.scoped.context", "true");
InitialContext initialContext = new InitialContext(env);
TestBeanRemote remote = (TestBeanRemote) initialContext.lookup(
"ejb:TestEar/TestBean/TestBean!com.test.TestBeanRemote");
but it says:
Exception in thread "main" java.lang.IllegalStateException: EJBCLIENT000025: No EJB receiver available for handling [appName:BilllingFacadeCallbackEAR, moduleName:BilllingFacadeCallback, distinctName:] combination for invocation context org.jboss.ejb.client.EJBClientInvocationContext#3b088d51

Is there any solution to call legacy jboss without old jars?
There is a legacy subsystem for this but I don't know its current status.
https://github.com/jboss-set/jboss-as-legacy
The CORBA standard defines an "across the wire" standard for making remote method calls called IIOP or "Internet Inter-ORB Protocol".
You need to set up to use CORBA IIOP in order to make platform independent remote EJB calls.
Therefore, you need to:
configure JBoss 5 so that it can handle incoming IIOP calls;
configure WildFly 10/EAP 7 to make outgoing EJB invocations using IIOP.
There is some information on this in the WildFly 10 EJB3 Reference Guide although I'm not sure how up to date that is.
The issue is normally caused by a transaction reaching it's timeout value.
So it may be that the application logic is correctly handling the scenario in this case and is not attempting to retry activity
It can have several issues :
connection: Connection broken
security : user/pass invalid
EJB missing: connected, but ejb is not there
SSL
Ports
IP Address
JBoss maintains a persistent connection to the other server, so when the client sees this message it means there is no connection to a server that has the ejb you are trying to call, so a message will be logged when the connection fails to the other server.
Caused by: java.lang.IllegalStateException: EJBCLIENT000025: No EJB receiver available for handling
Can you clarify the below:
1# is your EJBs deployed on jboss 5.0.1?
2# You are invoking the EJBS from Wildfly 10 or EAP 7, means your client is deployed in Wildfly 10 or EAP 7?
I am using an embedded Jetty server to provide Web Services (using Jetty-JAXWS2-SPI to allow Jetty to serve the requests) and I am seeing the following errors when a connection terminates from my JAX-WS test client (generated by wsimport):

Even though these are not important errors (logged at DEBUG level) and I only see them from my test client, not from soapUI or the 'real' (.NET client), I would rather not see them at all.
I guess the problem is caused by the socket behavior within the JAX-WS client? Is there any way to influence the socket behavior to avoid this issue?
Other information:
Others have reported this issue on the Jetty mailing list, also when providing Web Services using Jetty-JAXWS2-SPI.
I am using JDK 1.6.0_24 and the JAX-WS implementation it contains.
I am using Jetty 7.3.1-20110307
I am new to jboss and i have been asked to incorporate jboss connection pooling mechanism with an existing web application. Considering that a web application database layer is properly written i.e. all resultsets, statements and connections being closed properly when not needed, What all code changes i will have to make in my web app after i have configured the jboss datasource properly.
Can anybody please point me to a tutorial or a code sample which uses jboss datasource in a web app.
first create an xml file by name xxx-ds.xml and place this file in server/default/deploy/xxx-ds.xml
<datasources>
<local-tx-datasource>
<jndi-name>/jdbc/Exp</jndi-name>
<type-mapping>SQL</type-mapping>
<connection-url>jdbc:microsoft:sqlserver:// </connection-url>
<driver-class>com.microsoft.jdbc.sqlserver.SQLServerDriver</driver-class>
<user-name></user-name>
<password></password>
<min-pool-size>5</min-pool-size>
<max-pool-size>1000</max-pool-size>
</local-tx-datasource>
</datasources>
jboss-web.xml
<jboss-web>
<!-- <security-domain flushOnSessionInvalidation="false"/>-->
<!-- <context-root>/BSI</context-root>-->
<resource-ref>
<description>Database connection resource</description>
<res-ref-name>jdbc/Exp</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<jndi-name>java:/jdbc/Exp</jndi-name>
<res-auth>Container</res-auth>
</resource-ref>
</jboss-web>
web.xml
<resource-ref>
<description>Database connection resource</description>
<res-ref-name>jdbc/Exp</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
and now in your .java file
javax.naming.Context ctx1 = new javax.naming.InitialContext();
javax.sql.DataSource ds = (javax.sql.DataSource) ctx1.lookup("java:comp/env/jdbc/Exp");
con = ds.getConnection();
***** make sure that resource ref name should be same in all place
The pool in JBoss is all handled in the DataSource configuration. Here is the HowTo. The web app would have to do a JNDI lookup for the datasource to get the database connection rather than doing a direct JDBC URL, and then you will have pooling.
Transactions are another story, though.
EDIT: In response to your comment about how this affects the code, this is what it looks like:
String jndiPath = "java:DataSourceJNDIName"; //The exact prefix here has a lot to do with clustering, etc., but if you are using one JBoss instance standalone, this works.
Context ctx = new InitialContext();
DataSource ds = (DataSource) PortableRemoteObject.narrow(ctx.lookup(jndiPath), DataSource.class);
Connection c = ds.getConnection();
Technically speaking the PortableRemoteObject.narrow isn't necessary in a JBoss (4.2.2 anyway) single server configuration for sure, but it is more proper J2EE standard code, as general application servers don't have to return an object of the right type just for doing a Context.lookup.
The above doesn't cover the resource utilization and error handling issues. You are supposed to close that Context object when you are done with it, and of course the database connection, although JBoss will yell at you if you forget to close the database connection and the transaction ends, and close it for you.
Anyway, that Connection object is usable just as much as DriverManager.getConnection(url);
You don't have to change anything.
When you select the right kind of data source (local-tx-datasource / xa-datasource), connection handling and TX is done for you. In $JBoss/docs/examples/jca you will find templates for virtually every database, that you can just reuse.
If you are using XA, you need to configure Tx-recovery. See this posting on a how-to:
http://management-platform.blogspot.com/2008/11/transaction-recovery-in-jbossas.html (well, perhaps not a how-to in the standalone mode, but in conjunction with the Jopr source code).
