Using struts in dm server gives http status 503 error

[gohil]

Hi,

I developed an enterprise application using spring, struts and hibernate, now I want to transfer it to work with OSGi dm server.

I found a book "Pro SpringSource dm server" where the author has explained a way to migrate WAR to OSGi bundles. I successfully migrated the application given in book.

The first step of migration says that remove the lib folder in WEB-INF directory and import all the relevant packages. I did the same. Application has been successfully deployed in the dm server.

But when I tried to connect to URL it is giving me the error:

SpringSource dm Server - Error report

HTTP Status 503 - Servlet action is currently unavailable

type: Status report message: Servlet action is currently unavailable

description: The requested service (Servlet action is currently unavailable) is not currently available.
What could be the reason for this?

I am out of clues to solve this issue. Can you pass any help you may have.

Thanks in anvance.

Look in serviceability/logs/log.log to see if there is a stack trace or other error to give you a clue about the cause of the failure. Once you see something, try googling it as vanilla Tomcat users may have hit the same problem. If it's class loading or resource finding related, then you have to start scratching your head and asking whether you have the correct set of package imports and exports in your bundles.

Hope that helps!

Thanks Gyln.

I looked into the serviceability\logs\logging.log; Below is the log.

------------
As seen there is no error, last three line shows that deployment completed succesfully.
Then where could be the error? Could you pass any pointer on this?

I heard about Struts OSGi plugin. Is it required to run my application?

Thanks in advance

Hmmm. That log actually looks like the event log which is in serviceability/eventlogs/eventlog.log.

The diagnostic log serviceability/logs/log.log contains entries like this:

[2010-04-06 11:20:49.835] startup-tracker              com.springsource.osgi.medic.eventlog.default                     KE0001I Kernel starting.

Please confirm that you really are looking at serviceability/logs/log.log.

If so, have you changed the file config/serviceability.xml?

[gohil]

Thanks Glyn again.

There is no entry for

• serviceability/eventlogs/eventlog.log
• config/serviceability.xml

as I am using dm server version 1.0.2.SR02 and haven't changed anything in config directory and I posted the entry of serviceability\logs\logging.log previously.

However I found something in serviceability\trace\LibTEMgt-0\trace.log;

Attaching trace.log file as I am not able to post of too long contents in the file (This file contains all the execution that I did with application but I am posting only last execution trace of application)

I found eventlog.log and serviceability.xml entries in dm server version 2.

So I am trying to deploy app. in dm server version 2. Does it make any difference?

Thanks in advance,
Gohil

[Glyn Normington]

It probably won't make much difference deploying in dm Server 2, but at least I won't confuse you by talking different terminology!

trace.log in v1 became log.log in v2.

So, did you find anything suitably suspicious in the trace.log you attached?

[gohil]

I found:

[2010-04-07 14:20:01.575] async-delivery-thread-1             org.springframework.web.context.ContextLoader.unknown E Context initialization failed

and

First one says that it is not able to find class for particular bean but I am not able to figure out second one.

Could you put your pointer on this?

Thanks in advance,
Gohil

Hi Glyn,

Thanks a lot for your help...

I analyzed the trace.log and now I am successfully able to run application though it is giving me some error on database connection but I think I will solve it.


Thanks,
Gohil

Glad to hear you are making progress. Please post back here if you learn any general lessons that could benefit others.
