Hi,

I am working with decition tables, I have differents xls files with
rules and I want to add multiple xls files to the same rulebase and
they will be merged into a single package.
I do the following:


private static RuleBase readTablaDecision() throws Exception {
               //read in the source
       final SpreadsheetCompiler converter = new SpreadsheetCompiler();
       final String drl = converter.compile( "/reglaPrincipal.xls",
InputType.XLS );
               PackageBuilder builder = new PackageBuilder();
               builder.addPackageFromDrl( new StringReader( drl ) );

               final String drl2, drl3;
               if((dj.getVersion()!=null)&&(dj.getVersion().compareTo("Version
1")==0)){
                       drl2 = converter.compile( "/reglaVersion1.xls",
InputType.XLS );
                       builder.addPackageFromDrl( new StringReader( drl2 ) );
               }

               Package pkg = builder.getPackage();
               RuleBase ruleBase = RuleBaseFactory.newRuleBase();
               ruleBase.addPackage( pkg );
               return ruleBase;
       }

When I run the program, the following error message appear:

org.drools.compiler.PackageBuilder$PackageMergeException: Can't merge
packages with different names. This package: com.ReglaPrincipal - New
package: com.reglaVersion1
       at org.drools.compiler.PackageBuilder.validatePackageName(PackageBuilder.java:325)
       at org.drools.compiler.PackageBuilder.addPackage(PackageBuilder.java:236)
       at org.drools.compiler.PackageBuilder.addPackageFromDrl(PackageBuilder.java:167)


Can I work with severals xls files?
