check if the filter from referenced libraries is called succesfully or not

Question

I have a filter in one of the referenced libraries. I have configured this filter in web.xml of my application.

Consider I have the filter in abcd.jar.

I am configuring it to my web.xml as

<filter> 
    <filter-name>message</filter-name>
    <filter-class>com.test.myfilter</filter-class>
    <init-param> 
      <param-name>message</param-name>
      <param-value>A message for you!</param-value> 
    </init-param> 
  </filter> 
  <filter-mapping> 
    <filter-name>message</filter-name>
    <url-pattern>/test/filter2*</url-pattern> 
    <dispatcher>REQUEST</dispatcher>   
  </filter-mapping>

When browsed the url containing the match localhost:8080/test/filter2.jsp. I could access this correctly. But not sure whether my filter is called successfully or not.

I cannot test it by adding the print statements in the filter class because it is from referenced libraries.

Is there any other way to test it.

Is there a condition on which filter acts differently then normal? Like not logged-in or invalid number of parameters, etc.... use that condition to check if its working. — Harry Joy, Feb 25 '13 at 07:13
@HarryJoy. I think there is no such condition. Can I change the name of the parameter and check.. — Patan, Feb 25 '13 at 07:16
Then what does it filter? which kind of request does it filter? make a request that doesn't pass the filter condition. — Harry Joy, Feb 25 '13 at 07:17
@HarryJoy.This is the filter applied to soap based web service. It is adding some MimeHeaders to soap request. — Patan, Feb 25 '13 at 07:22

Create method break-point in your third party jar file. And then wait to see if the break-point is triggered or not.

For creating the break-point in third party library in eclipse, open the class file in your jar in project explorer, then open the outline, right click and add the break-point.
