UploadContent CWS 10.5 throws an error java.lang.NullPointerException

Hi,

We are trying to create a wrapper for a livelink client, to add some additional features to it. For this purpose, we have generated the java proxies for the livelink endpoints using the wsimport tool. Our code is simple, the first thing that we do is getting a valid token for uploading a document. We fill the appropriated soap headers, including, livelink token, mtom chunks size, context id, etc.

When we call to uploadContent method we obtain the following error:

Could you help us to solve this problem?.

Most webservice problems are debugged like this

The server or computer where the WSDL exists this should have a Web.Config.You can increase the logging here.It is actually in that Config file.
The WSDL's are just one part of a transport the real work is done by a LLserver(Oscript). The Web.Config actually has a livelink.host and a port ,this is the livelink server and port responsible for your command.Its logging can be increased by putting debug=true, wantlogs=true,wantlapilogs=true.If the <inArgs and the <outArgs indicate no trouble then the livelink server has done its job,and it may be some error in the webserver layer.The same info as in my blog a little more clearer if you are new to this.
When developing code send your request to a single LLserver many organizations do not know that tokens are cookies in disguise and unless you know how to properly set it up for a LB environment. OT also does not help out with anything leading to a successful LB architecture so most of the info around this is anecdotal.

You may want to try the simplest sample that OT has put out here https://knowledge.opentext.com/knowledge/llisapi.dll/fetch/2001/15080935/-15106263/15106294/15106295/17990637/62345549/download_Java.html

If that works then you could compare your code and go from there.

From your post it is not clear whether or not the WSDL's are in Tomcat or IIS sometimes some of that info will aid in helping.

It is Livelink period , for me

Well, if I called the wrongnumber, why did you answer the phone?

where you see this ".Its logging can be increased by putting debug=true, wantlogs=true,wantlapilogs=true.If" I meant to say this

.Its logging can be increased by putting debug=2, wantlogs=true,wantlapilogs=true.
