The stock standalone.xml configuration doesn't contain JMS support by default but standalone-full.xml. I thought of adding the messaging subsystem to the default configuration to make it easy. Here's how to do it :
The WildFly server would instantiate the JMS subsystem when you simply add the messaging subsystem with <hornetq-server />, as follows :
<subsystem xmlns="urn:jboss:domain:messaging:1.4">
<hornetq-server />
</subsystem>
However, adding the above configuration alone would not suffice. You have to tell the server to load the messaging module, which contains necessary libraries to host the JMS subsystem. We have to define the messaging module under the list of "extentions".
<extensions>
....
....
<extension module="org.jboss.as.messaging"/>
</extensions>
Although this configuration would accommodate JMS support in the server, it would still not support MDB deployment. The next step to define and configure an MDB container.
<subsystem xmlns="urn:jboss:domain:ejb3:2.0">
....
....
<mdb>
<resource-adapter-ref resource-adapter-name="hornetq-ra"/>
<bean-instance-pool-ref pool-name="mdb-strict-max-pool"/>
</mdb>
<pools>
<bean-instance-pools>
<strict-max-pool name="slsb-strict-max-pool" max-pool-size="20" instance-acquisition-timeout="5" instance-acquisition-timeout-unit="MINUTES"/>
<strict-max-pool name="mdb-strict-max-pool" max-pool-size="20" instance-acquisition-timeout="5" instance-acquisition-timeout-unit="MINUTES"/>
</bean-instance-pools>
</pools>
</subsystem>
The bean instance pools have already been defined in the stock standlone.xml file but you need to configure the MDB container within <mdb />.
JEE 7 with WildFly 8
I thought of playing around JEE7 on the upcoming WildFly 8. At the writing of this, WF-8-Alpha4 was the latest available and there's no GA. I will be starting with basics of WF and as I move on, I believe it should be ready and comply with the full JEE 7 TCK. Since I do have a very short lived memory, I believe writing every little detail would help myself in the long run. I doubt I would explore all components of JEE 7 stack, instead I would probably focus on JCA 1.7, Transactions 1.2, JMS 2.0 and EJB 3.2.
Installation :
WildFly-8 Alpha 4 can be downloaded from the community web at the following location :
http://www.wildfly.org/download/ or directly from
http://download.jboss.org/wildfly/8.0.0.Alpha4/wildfly-8.0.0.Alpha4.zip
The installation is pretty easy, just unzip the downloaded wildfly-8.0.0.Alpha4.zip to a preferred directory. The server would start the default standlone.xml configuration should you run ./standalone.sh from the $WF_HOME/bin directory. To list all available startup options, please try :
[bershath@shimmer bin]$ ./standalone.sh --help
To bind the application server to a specific port :
[bershath@shimmer bin]$ ./standalone.sh -b 192.168.1.50
The standalone.conf in the bin directory contains a few startup options, it's recommended to tweak these attributes to accommodate specific memory or user requirements.
