Application server error in http client

[Former Member]

Hello ,

I'm using cl_http_client , and when i execute my program ,i don't get a respinse :  p_content = http_client->response->get_cdata( )

I get an error : Application server error.

It seems a problem in service activation , but i don't know how to fix it.

Thank  you

Hi ,

The details are not enough to get you a proper solution, perhaps some print-screens can help. What are your SAP product you have been using?? The database or OS??

Thanks,

Check whether your ICM services if required, restart once the ICM service. Also check for the program with your Developer if its required to activate the Program/Table, generally in ECC system can be achieved via SE11. I guess, as The current SCN is moving now to the new SCN Site  http://people.sap.com, you have to wait until Monday & then maybe required to re-post this matter after that.

Thanks,
