Error with: org.eclipse.jdt.internal.compiler

[dobinhtru]

Hi All,

I have a sample about Jasper Report.

I used Eclipse Helios Release and Tomcat 6.0

Libirary:

jasperreports-0.6.5.jar

and jdt-compiler-3.1.1.jar

When deploy this sample to Tomcat and browser,it no have proble but when I run to view jasper report,it throw exception:

Exception in thread "Thread-8" java.lang.NoSuchMethodError: org.eclipse.jdt.internal.compiler.env.NameEnvironmentAnswer.<init>(Lorg/eclipse/jdt/internal/compiler/env/IBinaryType;)V

Please help me about this problem?(I think this problem is version or conflict of jdt.jar)

Thanks
