We are using JBoss ESB 4.3, is it possible to pass primitive variables to org.jboss.soa.esb.actions.EJBProcessor, how?

I know i can try another technique like creating a custom class and have an boolean as its property. But M looking for simple solution without creating a class.

<property name="ejb-params">

      <arg0 type="java.lang.String">username</arg0>

      <arg1 type="java.lang.Boolean">true</arg1>

  </property>

My method is like this-

public void demo(String value, boolean value){

}

So above technique of passing parameters won't work, I need something like this-

<property name="ejb-params">

      <arg0 type="java.lang.String">usename</arg0>

      <arg1 type="boolean">true</arg1>

</property>

This doesn't works because it is looking for class named boolean.
