HTTP 500 internal server error while starting abap web dynpro application

[former_member94854]

Hi there,

i have some problems concerning my web dynpro abap configurations in the system. When i start an application the browser appears and displays the http 500 internal server error. The required icf nodes are activated, as far as i know. the following properties are set:

hostname: aet

port: 8000

The generated url for the web dynpro application looks as follows:

http://aet.ls3001:8000/sap/bc/webdynpro/sap/zwdr_test?sap-language=EN

Maybe anybody of you out there has an idea for that situation.

Thanks for your afford and kind regards,

Albert

Hi Albert,

the 500 internal server error overwrites the error text send from server.

Follow note 529793 to change the settings in the browser. Run your application again and let us know what the error says.

English:

"Tools" -> "Internet Options ..." -> "Advanced" -> Ausschalten

der Option "Show friendly HTTP error messages".

German:

Extras -> Internetoptionen -> Erweitert -> Ausschalten der Option

"Kurze HTTP-Fehlermeldungen anzeigen"

Hi Ulli,

the error message says:

UNKNOWN HOST

Description: Unable to locate the server named "aet.ls3001" --- the server does not have a DNS entry. Perhaps there is a misspelling in the server name, or the server no longer exists. Double-check the name and try again.

So the problem is the hostname.

When i replace the hostname with the ip of the server, the following error occures:

COULD NOT CONNECT

Description: Could not connect to the server "10.18.187.9".

But with SAPLogon, its possible to connect on the server by filling in the ip adress.

Kind regards,

Albert

Hi Albert,

i'm afraid this is more a network administration problem than a wd related one.

Have you discussed the problem with your network admins?

I guess you really have to follow and check the points given in the documentation for setting up icf and icm. (link provided in Heidi's post)

Hi collegues,

thanks for your help. Unfortunately, it was rather a network problem than a web dynpro settings problem . Now we have a static ip address and a DNS entry and it works.

Kind regards,

Hi Albert,

the necessary settings (in sicf and smicm) which Thomas talked about are described unter the section Prerequisites : http://help.sap.com/saphelp_nw04s/helpdata/en/fa/a5554a1de4964e8459851782eddda3/frameset.htm

Hi Albert,

I was wondering if you have all ICF nodes active according to note 517484?

Best regards,

Thomas

Hi Thomas,

just in case, i activated all available services for the icf. May it be, that the https protocol should be created in the icm service list, Because of the actions during logon?

Kind regards,

Albert

Hi Albert,

Yes, icm needs to be configured properly as well.

Best regards,

Thomas
