I am using Jboss 7.1 Final. I have setup remote ejb using jboss-ejb-client.properties and standalone.xml accordingly. But after the server running for sometime it will throw this exception while trying to lookup the remote ejb. Is there anything I need to set in the jboss-ejb-client.properties in order for it to work. Note that I already defined the HEARTBEAT_INTERVAL, is that not enough?
Here is the properties file:
endpoint.name=client-endpoint
remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false
remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false
remote.connections=default
remote.connection.default.host=222.222.23.222
remote.connection.default.port=4447
remote.connection.default.username=us
remote.connection.default.password=ps
remote.connection.default.connect.options.org.jboss.remoting3.RemotingOptions.HEARTBEAT_INTERVAL=60000
Since no takers to this question, I found some possible solutions by googling. It might be that I have been opening too many connections by calling new InitialContext() -- I might be calling it every few minutes!!! See this link:
https://developer.jboss.org/thread/222883
In there someone mentioned GC and the connection closing etc. That might be helpful.
How do you lookup to your EJB from your EJB Client ? Incase you are using java:/ namespace the problem will happen.
Please use ejb:/ namespace to eliminate the problem.

I am getting the following error when trying to connect my application to jboss:
WARN | ISPN004022: Unable to invalidate transport for server:
/127.0.0.1:12222 ERROR | ISPN004017: Could not fetch transport
org.infinispan.client.hotrod.exceptions.TransportException:: Could not
connect to server: /127.0.0.1:12222
Tried searching a lot for a solution. It would be great is someone could help me out with this. Thanks
You must recall the following actions:
Make sure that your webapp is using the same port as defined in the socket-binding definitions for hotrod in the standalone.xml for JDG configuration folder;
Make sure that your webapp is using the proper inject annotations for your RemoteCacheManager class (remember to use the #ApplicationScopped annotation at the class definition and for additional methods used to get the cache instance);
If you are using JBoss and JDG on the same host, you must check declarations of the JBOSS_HOME environment variable. This variable must be assigned to the JDG installation home directory and not the JBoss EAP home (check also port-offset settings at startup if you're using a custom shell script);
If you are not using both products on the same host, check firewall and network settings;
Remember to re-deploy the application always after every modification and check both EAP and JDG console output for warnings and/or errors.
The following errors are related (for example):

I need to upgrade a weblogic domain to 12.2.1 from 12.1.3. I tried to use the reconfigure.sh weblogic utility. While using that utility, i am getting the below exception. The old domain is from weblogic 12.1.3. Any clues?
Exception in thread "Thread-4" java.lang.IllegalArgumentException: Invalid host:port

I had the same error. In my case it was cause about the custom DataSource configured in the domain, specifically with a data source configured as GridLink without ONS configuration.
As I resolved was, first I made a backup of config.xml file, then I removed all the custom datasource references, like this:
<jdbc-system-resource>
<name>mds-soa</name>
<target>soa_cluster,AdminServer</target>
<descriptor-file-name>jdbc/mds-soa-jdbc.xml</descriptor-file-name>
</jdbc-system-resource>
<!--jdbc-system-resource>
<name>OrchDS</name>
<target>jms_cluster</target>
<descriptor-file-name>jdbc/OrchDS-1529-jdbc.xml</descriptor-file-name>
</jdbc-system-resource-->
Be careful, when you reconfigure the domain, all the comments in the config.ml file was removed.
Then start the wizard for reconfig the domain until setup progress windows, just to make sure you pass all the validations and then exit.
Add one by one until found the descriptor file who has the error.
I hope this help you.
I just tried to do a attempted a seamless upgrade of a service in a test setup. The service is being accessed by a Feign client. And naively I was under the impression that with multiple instances available of the service, the client would retry another instance if it failed to connect to one.
That, however, did not happen. But I cannot find any mention of how Feign in Spring Cloud is supposed to be configured to do this? Although I have seen mentions of it supporting it (as opposed to using RestTemplate where you would use something like Spring Retry?)
If you are using ribbon you can set properties similar to the following (substituting "localapp" for your serviceid):
localapp.ribbon.MaxAutoRetries=5
localapp.ribbon.MaxAutoRetriesNextServer=5
localapp.ribbon.OkToRetryOnAllOperations=true
ps underneath Feign has a Retryer interface, which was made to support things like Ribbon.
https://github.com/Netflix/feign/blob/master/core/src/main/java/feign/Retryer.java
see if property works - OkToRetryOnAllOperations: true

I've been working on a web application, deployed on Tomcat 7, which use EclipseLink JPA to handle the persistence layer.
Everything works fine in a test environment but we're having serious issues in the production environment due to a firewall cutting killing inactive connections. Basically if a connection is inactive for a while a firewall the sits between the Tomcat server and the DB server kill it, with the result of leaving "stale" connections in the pool.
The next time that connection is used the code never returns, until it gets a "Connection timed out" SQLException (full ex.getMessage() below).

2.3.0.v20110604-r9504): org.eclipse.persistence.exceptions.DatabaseException Internal
Exception: java.sql.SQLException: Eccezione IO: Connection timed out
I already tried several configuration in the persistence.xml, but since I have no access to the firewall configuration I had no luck with these methods. I also tried to use setCheckConnections()
ConnectionPool cp = ((JpaEntityManager)em).getServerSession().getDefaultConnectionPool();
cp.setCheckConnections();
cp.releaseConnection(cp.acquireConnection());
I managed to solve the issue in a test script using testOnBorrow, testWhileIdle and other features that are avalaible from DBCP Apache Commons. I'd like to know how to override the EclipseLink internal connection pool to use a custom connection pool so that I can provide an already configured pool, based on DBCP rather than just configuring the internal one using persistence.xml.
I know I should provide a SessionCustomizer, I'm uncertain which one is the correct pattern to use. Basically I would like to preserve the performance of DBCP in a JPA-like way.
I'm deploying on Tomcat 7, I know that if I switch to GF I won't have this problem, but for a matter of consistency with other webapp on the same server I'd prefere to stay on Tomcat.
What you want is definitely possible, but you might be hitting the limits of the "do it yourself" approach.
This is one of the more difficult things to explain, but there are effectively two ways to configure your EntityManagerFactory. The "do it yourself" approach and the "container" approach.
When you call Persistence.createEntityManagerFactory it eventually delegates to this method of the PersistenceProvider interface implemented by EclipseLink:
EntityManagerFactory createEntityManagerFactory(String emName, Map map)
The deal here is EclipseLink will then take it upon itself to do all the work, including its own connection creation and handling. This is the "do it yourself" approach. I don't know EclipseLink well enough to know if there is a way to feed it connections using this approach. After two days on Stackoverflow it doesn't seem like anyone else has that info either.
So here is why this "works in GF". When you let the container create the EntityManagerFactory for you by having it injected or looking it up, the container uses a different method on the PersistenceProvider interface implemented by EclipseLink:
EntityManagerFactory createContainerEntityManagerFactory(PersistenceUnitInfo info, Map map)
The long and short of it is that this PersistenceUnitInfo is an interface that the container implements and has these two very key methods on it:
public DataSource getJtaDataSource();
public DataSource getNonJtaDataSource();
With this mode EclipseLink will not try to do its own connection handling and will simply call these methods to get the DataSource from the container. This is really what you need.
There are two possible approaches you could take to solving this:
You could attempt to instantiate the EclipseLink PersistenceProvider implementation yourself and call the createContainerEntityManagerFactory method passing in your own implementation of the PersistenceUnitInfo interface and feed the DBCP configured DataSource instances into EclipseLink that way. You would need to parse the persistence.xml file yourself and feed that data in through the PersistenceUnitInfo. As well EclipseLink might also expect a TransactionManager, in which case you'll be stuck unless you hunt down a TransactionManager you can add to Tomcat.
You could use the Java EE 6 certified version of Tomcat, TomEE. DataSources are configured in the tomee.xml, created using DBCP with full support for all the options you need, and passed to the PersistenceProvider using the described createContainerEntityManagerFactory call. You then get the EntityManagerFactory injected via #PersistenceUnit or look it up.
If you do attempt to use TomEE, make sure your persistence.xml is updated to explicitly set transaction-type="RESOURCE_LOCAL" because the default is JTA. Even though it's non-compliant to use JTA with the Persistence.createEntityManagerFactory approach, there aren't any persistence providers that will complain and let you know you're doing something wrong, they treat it as RESOURCE_LOCAL ignoring the schema. So when you go to port your app to an actual certified server, it blows up.
Another note on TomEE is that in the current release, you'll have to put your EclipseLink libs in the <tomcat>/lib/ directory. This is fixed in trunk, just not released yet.
I'm not sure how useful these slides will be without the explanation that goes along with them, but the second part of this presentation is a deep dive into how container-managed EntityManager's work, specifically with regards to connection handling and transactions. You can ignore the transaction part as you aren't using them and already have an in production you're not likely to dramatically change, but it might be interesting for future development.
Best of luck!
I need to be able to circumvent the whole deployer malarkey and programmatically register/unregister (dependency-less) POJOs as services in JBoss.
Currently I'm dynamically creating an MBean interface and registering this with the JBoss MBeanServer, and then registering local/remote with Jndi.
This works ok (I can have a standard service from a vanilla SAR reference one of these service POJOs with the #EJB annotation) - however the container seems to leaves stale references behind as after calling unbind() and unregisterMBean().
Obviously I'm missing something by not dealing with the container in a way it expects, but what am I missing? Or is there an easier way (can't see much in the way of an API)?
thanks.
