500 Internal Server Error

[Former Member]

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??

Pradeep,

*I suggest you to check your coding part , Mapping and binding.

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

[former_member189631]

Ok Predeep,

Yeah you are right. If nothing is done (Mapping and Bind) atleast it could

show the empty Page.

Why dont you restart the server ?

Could you Create archive,Rebuild,deploy your application properly?

Regards,

Ram.

[Former Member]

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.?

[Former Member]

Hi pradeep

This error comes oftenly if your coding part contains any problem. Try to check your code.

Pradeep,

*The server Might be down or Not Running.

*Please see the server node is indicating Green.

*I suggest you to restart the server by rightclick-->restart

Regards,

Ramganesan K.

[Former Member]

server nodes are in green color only.

[abhijeet_mukkawar]

can you ping the server from your pc ?

[Former Member]

hi

did u try restarting the server and deploying the application?

regards

prasy

[Former Member]

when i ping the server from preferences->jdi->development configurations its giving error <b>ping failed User credentials are invalid or user is denied access</b>

[Former Member]

i tried with restarting and deploying it. no change

[abhijeet_mukkawar]

check out the credentials with basis guys, check if they are authorised or not.

regards

[Former Member]

hi,

chk out the password of the deployment server with the server admin/BASIS. it might be b'coz ur r supplying the wrong password

[Former Member]

my team mate is accessing the same server with same credentials but he is not facing any problem.

[Former Member]

hi

try chkin out the firewall settings in ur system..mayb its preventing ur system from accessing the server

[Former Member]

Hi,

nothing has been changed, it was working well yesterday, suddenly today its happening. all the settings are same as yesterday.

[abhijeet_mukkawar]

hi,

can you ping your server from <b>command prompt</b>

regards

[Former Member]

yes i could able to ping the server from command prompt

[abhijeet_mukkawar]

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

regards

[Former Member]

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.

[former_member189631]

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

Regards,

Ramganesan K.

[Former Member]

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.

[abhijeet_mukkawar]

hi,

this error occurs when server's HTTP response is no ok, try to get the full stack trace by doing setting in Internet Option, check if you can ping the server.

regards

[luciano_leitedasilva]

Hi,

Please, post a more complete information, like the java stack trace and if the application is using a RFC model.
