Debug - servlet

Colud someone help me to how debug a servlet with tomcat and netbeans 3.5.1 ?
Thanks

If you're running on the Tomkat server, dropping debug statements in won't work. It does if you're running from the S!S ide that's a different question.
However, if you're running on the actual server, about the only thing you can do is to sprinkle Systm.out.println(String) commands through the code and watche the log to see what's going on.
If however you are running from the ide and you launch the server in debug mode. (You'll have to check the ide docs for specifics because I don't have them here with me) then you can drop debug markers in the code and it will stop and let you step through the code.
Regards,

{Q} Debuging Servlets with VCafe 4.0 using WebLogic as WEB server

Hi,
          I am trying to set up VCafe 4.0 to debug servlets deployed on WebLogic 5.1.
          I don't have any problem with default servlet debugging, but I don't know
          how to tell VCafe that my WEB Server isWebLogic. Any ideas?
          Greg Mirsky


What edition of VCafe is required?
          Enterprise, Professional or standard. I am now using JBuilder and anyone has
          experience comparing it with VCafe.

Does WLS support Debugging Servlets with JBuilder 3 ?

I have read all the news groups and it appears that WLS 4.5.1 does not
support debugging Servlets with Jbuilder 3.0.
I am using the trial version, does this matter ?
Or should I just buy another web server ?
Joe

I think below documents will be helpful to you.
http://docs.oracle.com/cd/E23943_01/apirefs.1111/e13952/taskhelp/webservices/webservicesecurity/CreateDefaultWSSConfig.html
This document tell you that you can attach a weblogic webservice configuration using weblogic admin console.
After creating this configuration you need to updated this configuration as per the steps given under :
Use X.509 certificates to establish identity

Debugging Servlet with JBuilder 6

Does anyone know how to debug a servlet with JBuilder version 6?
I have created the servlet without the wizard.
Thanks.
-Amar

You can use ServletExecDebugger from NewAtlanta.
You can download ServletExecDebugger at
http://www.newatlanta.com/products/servletexec/download.jsp
1. Extract ServletExecDebugger files to your local folder
2. Import ServletExecDebugger.jar file into you JBuilder
workspace
3. There will be ServletExecDebuggerMain.java file
Import that also.
4. Set ClassPath, Project Path , etc and off you go.
ServletExecDebugger comes with good documentation
for a free debugger.
I have been using it for sometime now (in both JBuilder and Visual Age) and find it relatively simple to setup and good for debugging servlets.
You cannot debug JSPs that much easier though !
Hope this helps..

Debuging servlet on weblogic

I am trying to learn to debug servlet on weblogic . In one of the site it is written as
Locate startWSL.cmd and add the following variable DEBUG_OPTS:
set DEBUG_OPTS = -Xdebug -Xrunjdwp:transport= dt_socket,address=1044,server=y,suspend=n
I am confused with this .Please tell me why is this necessary for debugging.
Thank you

Java uses the Java Platform Debugger Architecture to define how a Java debugger connects to a running Java application for the purpose of debugging that application. To enable an application for debugging, you have to add some parameters to the command line to specify a few things, like what transport will be used to transfer data, and if a socket-based transport, what port number should be used. Once you define those parameters on the command line and the application is running, you can specify the port number in the debug configuration of your debugger to make a connection to that running application.
You can read more about the various debugging-related command line options on the following page, which is just part of the larger JPDA documentation:
[http://java.sun.com/javase/6/docs/technotes/guides/jpda/conninv.html]
If you peruse the documentation for your favorite debugger, you can find information about connecting to remote Java applications, and it should give you similar information.

Debugging servlets in JDeveloper

Folks !
I just noticed that at least JDeveloper 3.2.3 doesn't let you debug a servlet that is not directly derived from HttpServlet. That is if I have a servlet class A derived from a Class B which then derives from HttpServlet, I only get to debug Class B and not Class A. This is a very stupid restriction (confirms my perception of these IDEs being toys). I am hoping JDeveloper 9i can handle debugging servlet derived from another class which in turn is derived from HttpServlet. can 9i users pl. confirm that ?
Also, given current restriction of JDeveloper 3.2.3 what option do I have other than upgrading to 9i (which I hope doen't have this problem) ? Remore debugging using JDPA ?
thanks for your help.

-Sanjay Kumar

Debugging servlet/JSPs ??

What IDE would you use to debug Servlet/JSPs ? I think that JBuilder can
only debug Servlets. What about VisualCafe, VisualAge ?

Currently it is a bug in JDeveloper 3.1.x. We will be fixing it.

Bug in JDev documentation re: debugging servlets

This is in the document titled "Using the Servlet Debugger Class" found in the JDeveloper electronic documentation.
I'll quote the first bit:
"You can use the ServletDebugger class to tailor the debugging environment to your servlets. Using the ServletDebugger class, you can specify:
the JDeveloper root directory
which servlet's to register with the JDeveloper web server. The servlets you specify will appear in the Servlet Launcher.
the document root directory for the integrated web server
the starting URL for the Servlet Launcher
the JDeveloper web server port
URL arguments
To configure the debug environment:
For an HTTP servlet or for any servlet created outside of the JDeveloper environment, import the following package in your servlet's Java file:
import oracle.jdeveloper.servlet.*;"
Whoops, this last part is wrong. It should instead be "import oracle.jdeveloper.debugger.*;" I could not get it to compile with the first one, but the 2nd one worked fine.

Alex,
Thanks for pointing this out.
This has been fixed for the JDeveloper 3.1 documentation.

Debug servlet failed after Enable Enterprise Application Profiler

1. run IDE
2. Enable Enterprise Application Profiler of AS in Runtime tab
3. restart the AS server in debug model
4. create web module includes jsp & servlet
5. new a breakpoint in servlet codes
6. debug it by click Debug-> Star Session-> Run in Debugger
result:
1. debug failed
2. if you Disable Enterprise Application Profiler and restart the AS, debug successfully
Did you meet the same issue before?
thanks,

Hi
Are you checking with latest updates. IF not, please connect to update center and update the IDE. The update has fixes for Profiler.

Debugging servlets

I'm using JDev 3.0 and I'm trying to debug my servlet. I have 2 problems:
1) Netscape is supposed to appear with the Servlet Launcher page, but doesn't. I have to run webapprunner.html by hand in order to launch my servlet.
2) Yesterday I was able to set breakpoints and step through the code, but today I see the popup:
Cannot debug project with Target JDK 'java version "JDK1.2.2_JDeveloper'" can only debug with Target JDK 'java version "JDK1.1.8_JDeveloper'"
The project was created to use JDK1.2.2 so I've been able to debug with it before.
bob

Hi,
The servlet launcher problem might be caused by a network router. We try to locate your IP address when we launch Web-to-Go.
Make sure when you start JDeveloper that you start it in 1.2 mode. The target JDK and the JDK you start JDev in must match for the debugger to work properly.
