[rules-users] Link for drools-server module

Sounds like you found a solution!

It could be worth you posting your configuration (including version of
Tomcat, Drools components and EL) back to the forum to help others.
Something showing the folder hierarchy and location of JARS would be
good. You could even dig out the wiki page relating to Drools and Tomcat
if you feel adventurous.

I don't know anything about the REST api etc. Sorry.

Hi Michael

I added the el-api 1.2  to tomcat 5.5.7/common/lib  ,and then the
drools-server started working.But then my web-client ,built on struts
and
using jsp not jsf ,started giving the same el-api error.

I am also working with tomcat 6.0.3  .I had added the jsf jars from
jboss
,but drools server and later my web - client application started to work
,but guvnor gave el-api version error.Because tomcat 6.0.3 had el-api
and
guvnor contained el-api 1.2  .So at last i removed the el-api 1.2 from
guvnor ,and replaced it in tomcat lib with el-api.

Bingo now all 3 guvnor ,drools-server ,and my web-client application are
deployed in tomcat 6 and working fine.

Still in need of a document describing ,the complete working of the rest
api
along with the web client to call drools server.

Thanks

Tanzu
