ArcGIS GeoEvent Processor - javax.xml.ws.soap.SOAPFaultException: unsubscribe failed

Background

I use wsimport to create, in effect, a Java web service client connecting to the web service. Net, which returns data (unfortunately). To be more specific, I am working on a project (inbound transport) for the GeoEvent package for ESRI ArcGIS Server 10.2 processors, but, in my opinion, more general terms can be answered with regard to JAXB and WSDL bindings. Bear with me since I haven't touched Java since college (10+ years).

For purposes of WSDL.Net, a DataSet is a polymorphic type whose actual layout is not determined until run time after the DataSet has been populated with data. This causes problems when you want to use this web service with nothing but .Net.

After some research, I managed to use wsimport to generate wsdl from webservice. Then I was able to compile a basic proof of a conceptual program that receives results from webservice as a DOM, then looks at that DOM as a nodelist.

Link:

My wsimport looks like this (domain names have been changed to protect the innocent):

C:\Development\ArcGIS\WSDL>wsimport -b http://www.w3.org/2001/XMLSchema.xsd -b xsd.xjb -keep -p com.somecompany.services -XadditionalHeaders http://services.somecompany.com/DataRetrieval.asmx?wsdl

Problem

Unfortunately, the same code base that worked in my proof of concept, getting results from a web service, fails as soon as I implement in ArcGIS GeoEvent Processor. My project is part of the OSGI package that will control the ArcGIS GeoEvent processor. The following is an error, as shown in the Apache Karaf log for the GeoEvent processor.

Based on this error, I understand that there is a problem with the way I made the binding in wsimport, referring to the general scheme for the links that I listed above. It seems that in the general scheme there are no definitions for some elements that exist as classes created by wsimport. These classes seem to be properly generated when I check the output from wsimport.

I did not enable WSDL due to wiring restrictions, but included them in later answers if necessary.

What am I trying to find out

  • How to interpret this error?
  • Why does the same wsimport-generated code used to access the web service in my basic proof of concept occur when I run it in ArcGIS GeoEvent Processor?
  • The error mentions JAXB and SAX, I do not knowingly refer to any of these libraries as proof of concept or to a project for ArcGIS GeoEvent Processor. Is it possible that the binding / decoupling of a web service is handled differently, with processing of the ArcGIS GeoEvent processor in JAXB / SAX and proof of concept?
  • What can I do to solve this problem?
    • Use different, custom, xsd and xjb that describe the expected scheme for a web service? I don’t know exactly how this will be done.
    • Use something other than wsimport to create webservice reference classes?
    • Change anything in the java environment for the ArcGIS GeoEvent processor?
    • Other options?
    • Fix seppuku, then this is not my problem?

Environment specification

  • JDK 7u17 (1.7.0_17) 64 bit. The ArcGIS GeoEvent processor uses this version of the JRE, so I am locked for this version to run. Although I did some development in 1.7.0_51 before I realized this.
  • wsimport - JAX-WS RI 2.2.4-b01
  • ArcGIS Server 10.2
  • ArcGIS GeoEvent processor extension
  • Karaf (used by ArcGIS Geovent Processor to run OSGI packages)

This is probably not the best answer to this, but this is what I came up with.

The ArcGIS GeoEvent processor that completed my OSGI project seems to be doing the additional binding / decoupling of the web service that I referenced in my application. The workaround that I used to get this .Net (returned DataSet) web services for working in Java was simply not acceptable for this shell from the GeoEvent processor.

My decision

I eventually created a secondary .Net web service that took DataSet values ​​and converted them to JSON and returned JSON strings. This fixed the problems that occurred when trying to reference a DataSet returning values ​​from a web service, now I was dealing with a simple JSON string. The wsimport of this JSON web service went smoothly without the need to work. I have uploaded recently imported web service files into my java project and now have no problems.
