LathaAdjMemberi am developing a web application on Webshpere 6.1. I have configured the connector for webshpere in MyEclipse.
When i am debugging, servlet debugging gets started fine. But after servlet init() method, application execution is getting stopped. I provided the application url in the MyEclipse Web browser and clicked on “Go to selected URL” button in debug Perspective. But break points in doPost() and doGet() method are never getting hit. Because of this issue i am not able to debug my application. Please let me know how to resolve this problem.
support-joyMemberLathaAdj,
Have you implemented protected void service()? Can you PM me your servlet?

support-joyMemberHey LathaAdj,
Your servlet code looks good. Can you clarify if you are able to run your application in the normal run mode? And if the problem is only when trying to debug. MyEclipse comes with Sandbox Tomcat. Can you deploy your application on tomcat and see if you are able to deploy and run, next try the debug.
Also, please copy and paste your installation detail. You can find it from MyEclipse > Installation Summary > Installation Detail.
LathaAdjMemberYes, i am able to run appln in run mode.

I have couple of questions
(1) In the debug view, suspended thread stack trace; following line is listed: “Source not found for ServletWrapper(ServletWrapper).init(ServletConfig) line: 220”. It does show doGet() method in the threads. Does it have any thing to do with not hiting break point in doGet() method.(2) What is the correct way of accessing servlet in debug perspective? Should i be using “Internal Web browser” or “MyEclipse Web Browser”?
support-joyMemberLathaAdj,
Thanks for the installation details. How are you deploying your application? As a WAR or EAR? Refer http://www.myeclipseide.com/documentation/quickstarts/websphere6/#eardeployment. Can you try by wrapping your web application around an EAR and deploy.
1. It could be a possibility. Can you investigate this ->
“Source not found for ServletWrapper(ServletWrapper).init(ServletConfig) line: 220”.
What is it referring at line 220?
2. It doesn’t matter what web browser you are using, be it internal(MyEclipse web browser) or external. If you are running your application in debug mode, once it hits the breakpoint, it will automatically direct you to the debugger. Also it depends on your configuration under Window > Preferences > General > Web Browser.
LathaAdjMemberI deployed appln as EAR
As you can see in my servlet code, there is no line 220 in it. Not sure what this message actually mean.
I have tried using both web browsers but no luck.
thanks,
Latha
support-joyMemberLatha,
I don’t have websphere6.1 with me. I am able to run and debug servlet using tomcat/jboss. Can you check if you can run/debug your servlet using tomcat? I will try to get a dev team member assist you on this.
Also line 220 could be referred in some other file. Can you double click on the stack trace and see, where this points to?
support-joyMemberLatha,
I have news for you. I have downloaded and configured Websphere 6.1 with MyEclipse and I am able to debug a servlet using MyEclipse. Please refer to the attached screenshot. The only difference is that I am using MyEclipse 7.1.1 and you are using MyEclipse 6.6. Try to download MyEclipse 7.1.1 and install in a separate location than your 6.6 and create a new workspace. See if you are able to debug.

I believe that is a reference to line 220 in ServletWrapper.java, not in your code.
LathaAdjMemberRay,
Error is “Source not found for ServletWrapper(ServletWrapper).init(ServletConfig) line: 220”. Is it possible i am missing some jar file which contains this ServletWrapper class in it? FYI – I don’t have any compilation errors.
thanks,
Latha
support-joyMemberLatha,
Can you check if you have servletwrapper class in your application? Else download the relevant .jar file. You can use docjar.org to locate your jar file. I have one more question, when you run the application in the debug mode, does it invoke the debugger? If yes, add breakpoints in init method, I need you to keep pressing [F5] till you reach your breakpoint. Also I would recommend you to add System.out.println() statements in doGet() and doPost() and see, if you can see these in the console window.
I have downloaded MyEclipse 6.6 and I am able to debug servlet. It hits the breakpoint just fine.
Since this is a coding issue, I would recommend you to cross post your queries to Java servlet forums. You may get more help there.
rmcvayMemberIt would be a referenced dependency. The source would be in the J2EE sources, which are not included in ME or any other IDE AFAIK.
support-joyMemberRay, you are right, the source would be in a J2EE resource rather than ME.
Thanks.
