[rules-users] Exposing the rule engine as a web service to be accessed by the client

[tanzu]

Dear prem

Entire day I struggled ,but in vain.Please help.I downloaded the
drools-5.0.1 CR1 war and ,removed el-api .jar as I am using Tomcat 6X.Even
added the required jsf ,jars as mentioned in

http://www.jboss.org/community/wiki/JBRMSjsfdependencies

I have myeclipse 6.5  ,with eclipse 3.3 bundled with it.I added drools5.0.0
eclipse-all plugin in the plugin folder of eclipse.I was able to create a
repoistory location ,but when the location was formed ,the packages below it
are not visible to me.

Guvnor connection wizard is completed, but the new Guvnor repository
connection does not appear in the Guvnor Repository Explorer. I cannot
expand the tree to view Guvnor repository contents.I access internet through
a proxy.

I even tried adding the drools5.0.0 eclipse-all plugin in eclipse 3.4 . Same
problem like above.

Am I missing some configuration settings,for my tomcat in the
drools-guvnor.war.

I have not read about guvnor.And the link you sent is also with guvnor.

Do you have any reference ,where guvnor is not used ,just simple drl files
in the drools execution server ,with how is the xml data sent from the
client to the server.

Really in a big mess.Deadline too close.Just 2 more days.


Please help

Regards
Tanzu
