Hi,

An error happens when i integerate and run migrated environment in blaze 6.7

The application works correctly when i run the rulesets in default mode

but when i enable the new execution mode "Optimized Inference" the following error occurs

I guess i have missed to include some essential jars.

Currently i have included the following jars in my application.

1) AdvisorSvr

2) InnovatorRT

3) Advisor

4) AdvCommon

Please point me to the right jar file essential for enabling the new execution mode.

Best Regards,

Sumesh

I have received an email from a potential customer (of Blaze Advisor) giving the same message:

java.lang.NoClassDefFoundError: at/dms/compiler/Compiler
java.lang.ClassNotFoundException: at.dms.compiler.Compiler
 

The file seems to be in Advisor67\lib\Ndkjc-2.1A-bin.jar. Hopefully this is what you need.

I have sent an email to the customer asking them to try with this jar file in the path. Im no longer on site helping them with the evaluation of Blaze Advisor, so I cannot try this myself. Im also interested in knowing when this file is needed, since I had already tested deploying the rule service on Tomcat and had no problems with this jar file not being in the classpath. I believe the customer is deploying on WebSphere.

Best regards

Thanks for the reply.

You are right i found the jar file it is Ndkjc-2.1A-bin.jar

and after that i added collection.jar also to enable optimized inference.

Enabling the new algorithm gives some errors like

invalid LHS operation without pointing to the exact cause of the error in the code.

This makes it difficult for people like us to move forward with these trials.

Forum is not so active i should say.
