Adobe Document Services - http Response 500 - How to configure the logging?

[Former Member]

We are building an application in Web Dynpro Java that fetches data from an R/3 system via an RFC connection and is then supposed to show said data in a pdf within an iview. For that task we want to use the InteractiveForm UIElement. We bind the data to its pdfSource in the iViewu2019s context. Currently the form only consists of a text field bound to one attribute element of the pdfSource context node.

The ADS webservice is configured according to the manuals found here:

http://help.sap.com/saphelp_nw70/helpdata/en/fa/0b700d6cfd4e03a8ec2186ba6ff4af/frameset.htm

and tested successfully under the following link

http://<portal_host>:<port>/AdobeDocumentServices/Config?style=document

However, when we execute the application, an error occurs in the webservice generating the pdf, namely Invalid Content-Type:text/html. The error occurs when the iView containing the form is shown for the first time, even before the attributes of the pdfSource context are filled with data (we expect to see an empty form).

As it seems the webservice is expected to return a MIME type of either application/pdf or text/xml (we donu2019t know for sure since the SAP manuals and forums are inconclusive here), but instead we get text/html. This seems to be due to the fact that the webservice exits with an http response 500 Internal Server Error (we used several network monitoring tools to confirm that such a response is sent). Since such http responses are but html files with an empty body, yet not xml or pdf, the aforementioned error does make sense to us, but we do not know what Internal Error has caused it.

The only help that SAP seems to provide for an error u201CInvalid Content-Type:text/htmlu201D in context with ADS points to an expiring password or otherwise poor configuration of the ADSUser, which (most certainly) is not our case here since, and as said above, the configuration was and can be tested successfully.

We then tried to view the logs for this error on the machine where the J2EE engine is running with ADS installed according to this (not very comprehensible) guide:

http://help.sap.com/saphelp_nw70/helpdata/de/97/ccfc3f0ac2c642e10000000a1550b0/frameset.htm

We cannot find anything relevant in the server.log of the Visual Administrator except this message (it is generated exactly when our error occurs u2013 the trace severity is set to ALL for all Adobe application elements according to manual):

******************************************************************************************

**************************************************************************************

There is no error.pdf to be found on the file system and since neither have we known nor are we told by the error message, whether the underlying cause is is a render error or connection error or configuration error or what not, we donu2019t know whether the error.pdf is supposed to be generated at all.

Or could there be any other reason why generation didnu2019t take place?

Furthermore we canu2019t seem to be able to find any logs more verbose or detailed about this issue - at least not within the Visual Administrator or the portalu2019s nwa.

How is it possible to properly debug the webservice for pdf-generation or at least to retrieve a fully detailed log containing all notifications and exception stack traces etc.?

I am assuming that we are making some basic mistakes regarding the logging configuration - but what?

Our goal is to know what causes the 500 Internal Server Error response that causes the Incorrect Content-Type exception.

We are using a NetWeaver 7.01 portal installation with Adobe Document Services 7.01 installed on a Windows Server 2003 platform.

Any help is highly appreciated!

Have you tried restarting the Java PDF object in Visual Administrator? Once you do all of your config, you have to restart the PDF object (sao.com/tc_wdpdfobject) for the changes to take place. I am assuming you've run all of the test programs in SAP (FP_TEST_00, FP_TEST_03, etc.). Is there any chance that the ADSUSER is locked somehow?
