Running Tomcat server in Debug mode?

Hi..
I am using Eclipse IDE to develop a Portal project.. I am also using Tomcat server for the same without using the default servers provided by eclipse..
My question is how do I run the Tomcat server in the "debug" mode?
Please help me..

Take a look at these links: http://plato.acadiau.ca/courses/comp/dsilver/2513/EclipseAndTomcatTutorial/
http://www.keyboardsamurais.de/2004/01/15/tomcat_tutorial_helloworld_for_complete_fools_-_english/
http://www-128.ibm.com/developerworks/opensource/library/os-ectom/?ca=dgr-lnxw16EclipsTomcat
I've found going through tutorials is a proven, quick way of getting up to speed with new tools and configurations.

Starting Server in Debug Mode - Need Some Advice Plz.

Hi Guys,
I have an EP SP 12 Server Running and I am trying to Start the Server in Debug mode from the Netweaver Developer Studio but when I right click the Server and try to choose Debug, the option is greyed out and even while viewing the Debug option from the SAPMMC I see that under the column Debug, it say 'Disabled' for the Server and Dispatcher.
Can anyone suggest how this can be done, I would appreciate any help as I have been working on this for some time.
Best Wishes,
John.

Hi John,
If the you cannot start the server in the debugging mode through the NWDS then you can try the other way round.
Through Config Tool:
You can enable the debuggine mode from the Config Tool as well. Just visit the following path :
C:\usr\sap\<SID>\JC<SYS_NO>\j2ee\configtool\configtool.bat
Click on the your instance. Then under the tab VM Environment, Set the DebugMode = true.
Restart the engine now. This will open the J2EE server again in the Debug Mode.
I hope this helps you!!

Re: Using already running Tomcat server for development.

Hi Nick,
Yes, you can use existing Tomcat Server for debugging app developed with
NitroX. And you can refer to Help > Help Contents > NitroX User Guide >
NitroX Tour > Running and debugging the application.
We do support Tomcat 4.0.x to Tomcat 5.0.x. If you need any further
assistance please get back to us.

Sorry if this has been covered anywhere else.Just wondering if you can use an existing tomcat server for debugging
webapps being developed in NitroX. I have a non dedicated server a
development server. Up until purchasing NitroX I have been using ant build
files to compile and re-deploy my apps into the running tomcat server.
Just wondering if I can do something similar thru NitroX and Eclipse.
Forgive me if I am missing something obvious, but I am new to eclipse.

How to run the forms under debug Mode?

Hi,
I run my form under debug mode by introducing a break point on a trigger. But i am receive the following error how to solve this issue.
JVM aborting and followed by the following one.
FRM-92101: There was a failure in the forms server during startup.
This could happend due to invalid configuration.
Please look into the Web-server log files for details.and additional information from Java console.
proxyHost=null
proxyPort=0
connectMode=HTTP, native.
Forms Applet version is : 10.1.2.0
oracle.forms.net.ConnectionException: Forms session <5> aborted: unable to communicate with runtime process.

Where and what file i want to look into this to solve this issue.
Good help will be appreciated. Thank in advance.
kanish

Kanish,
Lets start with a few of the basics, shall we. What JVM are you using (Jinit or Sun JRE and the version)? Based on the error you posted, I can infer that you are using Forms 10.1.2.0? Are you running a custom configuration in the formsweb.cfg and default.env? This could be the cause if you have modified the CLASSPATH setting in the default.env excluding core .jar files.
Typically, the FRM-92101 error is caused by a Java error; either a .jar is not found or invalid or not compatible with JVM, etc.
Have you tried clearing your Java Cache to check for a corrupt .jar?
Hope this helps,
Craig B-)

How to run labview program in debugging mode in windows 95 version

Respected all,
I am facing probelm while running probe.vi.
I received this command "connection to acquisition board was not found" when i run labview program.
I am using labview 5.1, fieldpoint FP 1000, NI-DAQ 6.5, Field point explorer version 1.6, Measurement and Automation Explorer 1.0.1.
I would kindly request you please help me how to run my program probe.vi in debugging mode in windows 95 version, so that i can locate where error occurs.
Thanking You
Yours faithfully
M.Vijay

Respected Norbert,
Thank you very much to for your help.
Norbert : Possible reasons are e.g. wrong IDs for measurement devices. If the error is connect to the FieldPoint, it is possible that it isn't configured correctly.
I am using Field point explorer 1.6, The Field point instrument FP 1000 and RS-232 port is using. It is confirmed that the field point instrument is working properly by LED light indication test.
Norbert: It sound like you are using DAQ devices (like PCI MIO 6952E) in the application. Are you sure that you select the correct device ID for this?
I am asking you to know, If i using Labview and Fieldpoint instrument FP 1000 to monitor my parameter interms of All, Channel 0, Channel 1, Channel 2, Channel 3, Channel 4, Channel 5, Channel 6, Channel 7 for my measurement.
But now i need to solve the command connection to acquisition board was not found, The expert say this command is due to there was no AT-AO-10 Analog Output board was present in CPU.
I do not find AT-AO-10 Analog Output board in my CPU, Previously the instrument was worked perfectly by other person who assembled everthing to measure temperature.
The only aswer know send by previous person is if my task does not imply the use of a DAQ you probably have to locate where the DAQ driver is called and exclude it from the program. try to run the program in debugging mode so that you can locate where the error occurs.
I do not know how to proceed his instruction. So i would kindly request you to please help me to solve my probelm.
I also removed AT-AO-10 software from device manager >> Data Acquisition system >> AT-AO-10 just now.
I also find GPIB version 1.30, when i remove in add or remove program, it say that Error removing the GPIB.
I am eagerly waiting for your help.
Thanking You
Yours faithfully

How to start server in debug mode by default

Hi,
Whenever the server starts it does not start in debug mode.
One has to manually start the "SDM" and "Server0" in the debug mode.
Is there a way I can make the server start in debug mode for the first time itself.
regards,
Saurabh

Hi Saurabh,
You can start the server in debug mode using config tool. Just open cofig tool (/usr/sap/<SYS ID>/JC<SYS NR>/j2ee/configtool/configtool.bat).
Click on the your instance. Then under the tab Servers Debug check Debuggable and also Enable Debug mode.
Restart the engine now.
However a word of caution: Starting the server in debug mode decreases the system performance. You should only start the dev server in debug mode.
Hope this helps.

-Dweblogic.debug.DebugServerLifeCycle=true
Debug options are available in weblogic based on the subsystem, such as security, jms, jdbc, deployment..etc

Thanks & regards
shiva

I am not sure, how can you do it on the fly, but if you want to restart the server here are the parameters you need to add to the java arguments
-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=$Port
(where Port will be any port you want to connect to).
Thanks

Thanks. Lax.

Tomcat is telling you there is no context configured to be available from "/". Normally, this would be the default tomcat ROOT webapplication but you somehow managed to remove it (this is not a problem really, in a production environment you don't want it). If you want a context to be available on '/', you need to mount one there. So either install a webapp in the webapps/ROOT folder, or set one manually to '/' in the server.xml file. Check the tomcat docs on how to do this. Here is an example:
<Host name="localhost">
 <Context path="/" docBase="/usr/local/mywebapp" privileged="true" debug="0">
 <Resources className="org.apache.naming.resources.FileDirContext" allowLinking="true" docBase="" />
 </Context>
</Host>
Good luck!

Error starting J2EE server in debug mode

I am trying to start the Sun 1.4 application server in a debug mode. I get an error
err:FATAL ERROR in native method: No transports initialized
: No such file or directory
Error [2] in bind() call!
Socket transport failed to init.
Transport dt_socket failed to initialize, rc = -1.
The setting in config.xml file is:-
debug-enabled="true" debug-options="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=1044
Any help will be appreciated.
Thanks,

I changed the port number and it worked. Not sure why port 1044 as specified in the Sun documentation doesnot work.

Restart the server in debug mode: How to drop saved passwords?

In NWDS server pane, I entered a wrong password when trying to restart my SAP AS Java in debug mode. Now I only get exceptions "com.sap.enginemanagement.UnauthorizedException: Incorrect login information provided" without a chance of changing the entered credentials. Restarting NWDS didn't work.
Any ideas?
Thx,
Christoph

Hi Christoph,
are you talking about the "Java EE" perspective and the "Servers" view within it? I tried it out and it does not behave properly.
Try the "SAP Management" perspective. Within the left hand tree open your system, expand the instance starting with "J..", expand the "AS Java" node and select the "Process Table" node. In the right hand table select the server0 process and chose from the context menu "Start Debug Session".
The SAP JVM offers some extra debug options. Expand the "Expert Mode" in the modal dialog. If you want to debug web applications select "code isolation" and unselect all other options. A password dialog will appear and you must enter the credentials for the operating system user, not for the AS Java administrator.
One table column is labeled "Debug", there you can see the currrent debug port.
Either you start now a "Remote Java Application Debug" debug session or you have a Java EE project and can create a "SAP Application" debug session.
Anyway to see your application threads in the debugger you have to access your web application with a special debug URL.
If your URL looks like this: "http://localhost:50000/myapp" you have to insert a debug token beween host part and the path and the URL becomes "http://localhost:50000/@@@DEBUG@@@/myapp". If you miss to modify the URL you will not see any thread.
If you want to get a "normal" debug behaviour just deselect all options in the debug dialog. You will see all threads, you do not have to modify your URL, but the server will restart after you detached the debugger.
Hope this helps.
Best Regards, Stefan
