Constructors Summary
Methods Summary
public java.lang.ObjectgetDescriptor()

return
the descriptor instance to associate with this XMLNode

        return descriptor;
protected java.util.MapgetDispatchTable()
all sub-implementation of this class can use a dispatch table to map xml element to method name on the descriptor class for setting the element value.

return
the map with the element name as a key, the setter method as a value

    
        Map table = super.getDispatchTable();
        table.put(RuntimeTagNames.JNDI_NAME, "setJndiName");
        return table;
public voidsetElementValue(com.sun.enterprise.deployment.node.XMLElement element, java.lang.String value)
receives notiification of the value for a particular tag

param
element the xml element
param
value it's associated value

public org.w3c.dom.NodewriteDescriptor(org.w3c.dom.Node parent, java.lang.String nodeName, com.sun.enterprise.deployment.JmsDestinationReferenceDescriptor ejbRef)
write the descriptor class to a DOM tree and return it

param
parent node for the DOM tree
param
node name for the descriptor
param
the descriptor to write
return
the DOM tree top node

public static voidwriteResoureEnvReferences(org.w3c.dom.Node parent, com.sun.enterprise.deployment.types.ResourceEnvReferenceContainer descriptor)
writes all the runtime information for JMS destination references

param
parent node to add the runtime xml info
param
the J2EE component containing ejb references
