Even the simplest modell fails to deploy

Hi folks,

I have a straneg issue with my Visual Composer - until yesterday I could develop, test and deploy my model (it's a quite simple one with User_DATA, a BAPI and two tables) without any problems. However, today it won't deploy anymoere.

I created a new model (even simpler with only USER_DATA and a table to display these) and tried to deploy it, but had no success either.

I tried the hint at:

https://wiki.sdn.sap.com/wiki/display/VC/VCdoesnotfinishdeploying

and also applied SAP Note 886209 where they speak of UNIX machines (which I'm on) with no graphics card.

https://service.sap.com/sap/support/notes/886209

I am stuck here - I could not find any good hint in my logs except these entries from the server.log. The VC Application log is empty, despite the fact that I set verbose logging for VC Server to true.

So these are my only logs I have and they are not too useful for me:

application [VC] Cannot send an HTTP error response [500 Application error occurred during request processing. (details: com.sap.engine.services.servlets_jsp.server.exceptions.WebIOException: An attempt to write after the stream had been closed.)].

The error is: com.sap.engine.services.servlets_jsp.server.exceptions.WebIOException: An attempt to write after the stream had been closed.

Exception id: [000B5DAFECDA006E000000370000555E000450A40B65C417]

the next log entry is:

application [VC] Cannot send an HTTP error response [500 Application error occurred during request processing. (details: com.sap.engine.services.servlets_jsp.server.exceptions.WebIOException: An attempt to write after the stream had been closed.)].

I tried to change my simple modell and added a form (as mentioned in the VC FAQ but this did not help either.

Can someone point me a place/log where I could get more detailled information?

Thanks to all of you,
