<span style="font-family:Verdana"><span style="font-size:12px">Hi Kachan, thanks for your reply!
I took a look in your post and tried to adapt my code, this is below:
# Strategy 1
KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent("myagent");
kagent.applyChangeSet(ResourceFactory.newUrlResource("http://localhost:8090/drools-guvnor/org.drools.guvnor.Guvnor/package/mortgages/LATEST"));
KnowledgeBase kbase = kagent.getKnowledgeBase();
FactType appType = kbase.getFactType("mortgages", "LoanApplication");
I copied the URL "http://localhost:8090/drools-guvnor/org.drools.guvnor.Guvnor/package/mortgages/LATEST" and past it on the browser, it downloads the file mortgages.pkg, so its correct right?
But executing this code I got "(null: 1, 1): Content is not allowed in prolog."
So I changed the line 2 to use
#Strategy 2
kagent.applyChangeSet(ResourceFactory.newClassPathResource("src/main/resources/mortgage-changeset.xml"));
The mortgage-charset.xml is below</span></span>

<span style="font-family:Verdana"><span style="font-size:12px">With this change I dont have error, but the variable appType returns null again.
The point here is, I am using Guvnor with guest user (no authentication) this could be the problem?
The URL from Strategy1 is corrected, I tested it. The file in Stragety2 is corrected to, I debug it and see the file inputstream.
TIA</span></span>

Hey,
Please read the above and see whether it can help you. I had the same
problem returning null. Then I stopped it and now doing in ESB to access the
resources using its rules processor. But sometimes the above discussion can
help you and if you have anything positive please let me know too. I was
trying my own example in fact and not the mortgage. I think this would help
both of us. Thank you.
Kachan
