Hi all,
when I am deploying my application in server it is giving "500 Internal Server Error". Even a simple project with default view when I create the application and deploying its giving this error.
the total page is looking like this
<b>500 Internal Server Error
Web Dynpro Container/SAP J2EE Engine/6.40
Failed to process request. Please contact your system administrator.</b>
please can anyone tell me why this is happening? what might be the problem??

as previously said, I am not at all using any code... not even single line of code.
create new WD project, gave project name
right click on component controller, create new component controller->gave name
right click on application->create new application->gave
save metadata, build and deployed.
It should show the default view. But giving the 500 internal error.
so no chance of code or mapping error
ya... everything i did perfectly. Rebuilding, deploying.
But i think there is some problem with archive. because, when iam creating DC's building it and CHECKIN to the portal(with out deploying), the changes are reflecting and i could able to see everything.
when i am creating archive and deploying it its giving error.
so could you please help me out what will be the problems due to archive and how to resolve those.?
Hi pradeep
This error comes oftenly if your coding part contains any problem. Try to check your code.

hi,
are you not getting the full stack trace, if not
In IE, turn off the "Show Friendly HTTP error messages" by choosing tools - internet options - advanced. Then the full error messages will be displayed, as well as the line number of the error.
also check this
are you using ADS?
if you are using RFC, from content admin try to test and ping your JCOs

I did as you said, still I am not getting stack trace. and I am not using ADS, JCO's,RFC's, nothing.
just creating project
creating component
creating application
build and deploy application.
as far i know, it should display a default view with the view name text view.
deployment finished successfully. and this error is coming.
Pradeep,
Please check these,
*Your code should be error Free. Please check your code
id giving exception.
*Check your Mapping and Binding
*Check the J2ee engine details in Preferences -->J2EE Engine
*Check you have Successfuly deployed your application.
*If you feel any of your code may give the exception then enclose them with
Exception Handling Blocks

Thanks for the quick response...
But even if i try the worst case... ie.. just creating a project, creating component controller and then creating an application. and just deploying that application. It should show the default view, right?? I am not able to view that also.
I didnt not write single line of code.
and in preferences->j2ee server, server is perfectly alright.
I am not at all touching RFC's. Its like a HELLO WORLD program.
others are also using the same server, but they are doing good.
There is no mappings, no bindings... nothing.
Hi,
Please, post a more complete information, like the java stack trace and if the application is using a RFC model.
Regards,
Luciano
