Hi All,

 

When I access the drools-server by URLConnection, I've always got such errors:

Can anyone help me to fix this problem? I've got the same errors when trying to run KnowledgeServiceServletTest.java from the drool-server source code.

 

Thanks,

Jing

Thanks a lot for your help!!!

How to make it consistent to the drools-server?

 

Thanks,

Looks like the version of drools on your server is different than your client. That would explain the class version issue

Can anyone help me to fix this problem? I've got the same errors when trying to run KnowledgeServiceServletTest.java from the drool-server source code.

 

Thanks,

Jing

Thanks!! It really helps!!! I was using Guvnor M4 with drools-server M5. Now I'm upgrading everything to M5. And it works!!

 

One more question, when I try to build/deploy drools-server from source, where should the drl file be put (e.g., the properties file contains: file=test_rules1.drl)? I know that the rule agent configurations are to be placed in the "resources" directory. Should the drl file be put in the same dir? Or a specific place?

 

Thanks,

Jing

Sorry, I should have stated that differently. The version you are getting from Guvnor, is different than the version the execution server has. Which version did u compile you packages on guvnor with?

Thanks a lot for your help!!!

                        try {

                                    outXML.flush();

How to make it consistent to the drools-server?

Looks like the version of drools on your server is different than your client. That would explain the class version issue

Can anyone help me to fix this problem? I've got the same errors when trying to run KnowledgeServiceServletTest.java from the drool-server source code.

 

Thanks,

Jing

Hi there, and thanks for your quick responses

A week or so ago I got a response to my question about instantiation of facts declared in DRL. I also got this from Edson:

> Also, if you use Guvnor to define your model, Guvnor is capable of

I've looked thru Guvnor UI, but was unable to find where this jar is to be retrieved from. Is there some undocumented API (or servlet) to be called to?

Thanks!

  Sorry, Michael just told me that he is not exposing that to users. My
mistake.

  What is your need? Would an API solve your problem?
