Defining metadata in jboss-aop.xml

[sushmam]

Hi,

I have two classes - POJO.java, and TEST.java. I have only one interceptor class which just gets the metadata associated with the invocation object and prints it.

I have defined a constructor level metadata only for the POJO class, but this gets called, even for the TEST class. How can I make the constructor-metadata specific only to POJO class?

Given below are the extracts from jboss-aop.xml, BillingInterceptor class, POJO and TEST classes.

a) jboss-aop.xml

<?xml version="1.0" encoding="UTF-8"?>
<aop>
<!-- Metadata -->
 <metadata tag="mdTest" class="*">
 <constructor class="POJO" expr="POJO()">
 <my-attribute># Pojo constructor</my-attribute>
 </constructor>
 <method name="someMethod">
 <my-attribute>Let us start</my-attribute>
 </method>
 <method name="secondMethod">
 <my-attribute>secondMethod</my-attribute>
 </method>
 </metadata>

<!-- Pointcuts -->
 <bind pointcut="execution(POJO->new())">
 <interceptor class="BillingInterceptor"/>
 </bind>
 <bind pointcut="execution(* POJO->someMethod(..))">
 <interceptor class="BillingInterceptor"/>
 </bind>
 <bind pointcut="execution(TEST->new())">
 <interceptor class="BillingInterceptor"/>
 </bind>
 <bind pointcut="execution(* TEST->secondMethod(..))">
 <interceptor class="BillingInterceptor"/>
 </bind>
</aop>

b) BillingInterceptor.java

public class BillingInterceptor implements Interceptor
{
 public String getName() { return "BillingInterceptor"; }

 public Object invoke(Invocation invocation) throws Throwable
 {
 System.out.println("my-attribute : " + invocation.getMetaData("mdTest", "my-attribute"));
 return invocation.invokeNext();
 }
}

c) POJO.java

public class POJO
{
 public POJO()
 {
 System.out.println("pojo empty constructor");
 }
 public void someMethod(String str, int i, long l){
 System.out.println("someMethod: str=" + str + ", int=" + i + ", long=" + l);
 }
}

d) TEST.java

public class TEST
{
 public TEST()
 {
 System.out.println("testcons");
 }
 public void secondMethod(int newfoo)
 {
 System.out.println("in second Method --> " + newfoo);
 }
}

The o/p when I run the above program is:

 [java] --- new POJO(); ---
 [java] my-attribute : # Pojo constructor
 [java] pojo empty constructor
 [java] my-attribute : Let us start
 [java] someMethod: str=testSTr, int=5, long=55
 [java] --- new TEST(); ---
 [java] my-attribute : # Pojo constructor
 [java] testcons
 [java] my-attribute : secondMethod
 [java] in second Method --> 567

The attribute # Pojo constructor is being printed out by both the constructors. How to make this specific to only POJO class? Any pointers in this regard will be greatly appreciated.

Thanks,
Sushma.
