Hi all,
I am trying to use a ThreadPool in my application. In the plan.xml file, I
have:
<gbean name="DefaultThreadPool"
class="org.apache.geronimo.pool.ThreadPool">
<attribute name="keepAliveTime">5000</attribute>
<attribute name="poolSize">10</attribute>
<attribute name="poolName">DefaultThreadPool</attribute>
</gbean>
<gbean name="MyGBean" class="task.MyGBean">
<!--
<reference name="APrinter">
<name>gbean1</name>
</reference>
<reference name="BPrinter" >
<name>gbean2</name>
</reference> -->
<reference name="Executor">
<name>DefaultThreadPool</name>
</reference>
</gbean>
And on the file MyGBean.java I have a reference to it:
infoFactory.addReference("Executor",org.apache.geronimo.pool.ThreadPool.class,NameFactory.GERONIMO_SERVICE);
ant it is set via setter injection as follows:
public void setExecutor( org.apache.geronimo.pool.ThreadPool Executor ){
this.Executor = Executor;
}
Yet, it is not working, I get a "java.lang.IllegalArgumentException: cannot
find matching method/constructor" so MyGBean fails to start because
(according to the log) :
12:38:40,328 ERROR [GBeanInstanceState] Error while starting; GBean is now
in the FAILED state:
objectName="geronimo.server:J2EEApplication=null,J2EEModule=ibmtask/IBMTask,J2EEServer=geronimo,j2eeType=GBean,name=MyGBean"
java.lang.IllegalArgumentException: Cannot find matching method/constructor

an if I use the following as a reference:
infoFactory.addReference("Executor",org.apache.geronimo.pool.ThreadPool.class);
I just get on the log:
12:47:30,968 ERROR [GBeanInstance] GBeanInstance should already be stopped
before die() is called:
objectName=geronimo.server:J2EEApplication=null,J2EEModule=ibmtask/IBMTask,J2EEServer=geronimo,j2eeType=GBean,name=MyGBean

because no targets are running for reference Executor matching the patterns
geronimo.server:J2EEApplication=null,J2EEModule=ibmtask/IBMTask,J2EEServer=geronimo,j2eeType=null,name=DefaultThreadPool
Any help on how to deal with a ThreadPool will be helpful.
Thanks,
Nelson.
