[rules-users] Cannot load Dialect..

Hi, I am a drools 4.0.7 user. I am working on a drools project. The code works fine when I run it as a standalone application in Eclipse(all the rules fire as required) However , when I deploy the same code as a web service on Axis2, I get as exception as follows :- * org.drools.RuntimeDroolsException: Unable to load dialect 'org.drools.rule.builder.dialect.mvel.MVELDialectConfiguration:mvel'* I have included all the necessary Libraries in the archive file( .aar) of my service. Still it is giving me a exception . The exception occurs when I try to compile my Decision table in the following line of code... final SpreadsheetCompiler *converter* = new SpreadsheetCompiler(); final String drl1 = converter.compile( excelFile, InputType.XLS ); ....The SpreadsheetCompiler object i.e. *converter* is created while the web service is running ie itz not null. hence i think the drools library is accesible to the service.. Can please anyone help me out here.... Thanks in advance... Kiran Narasareddy Computers make very fast, very accurate mistakes.
