Hi,

The idl compiler does define those symbols. You should not need to 
compile orb.idl (its been done for you). I think you would need

  <plugin>
                 <groupId>org.codehaus.mojo</groupId>
                 <artifactId>idlj-maven-plugin</artifactId>
                 <executions>
                     <execution>
			<id>1</id>
                         <goals>
                             <goal>generate</goal>
                         </goals>
                         <configuration>
                             <sources>
                                 <source>
                                     <includes>
                                         <include>orb.idl</include>
                                     </includes>
                                     <additionalArguments>
 
<additionalArgument>-ir</additionalArgument>
 
<additionalArgument>-sloppy_forward</additionalArgument>

                                     </additionalArguments>
                                 </source>
                             </sources>
                         </configuration>
                     </execution>

to compile orb.idl
