java.lang.LinkageError: loader constraint violation: loader in Jasper Reports

[lelo.endrik]

Greetings everyone

I'm using JDeveloper version 11.1.2.3.0 and iReport 5.1.0.

I've created an application where users can upload their own jrxml files, these files gets compiled and stored in the FS. When users need to generate the PDF reports they can select one of the report types from those uploaded and generate the report.

Everything was working fine at first, but after some tests i've got this error, only on the report filling part:

javax.faces.el.EvaluationException: //C:/Users/Endrik/AppData/Roaming/JDeveloper/system11.1.2.3.39.62.76.1/o.j2ee/drs/ContractManagement/ViewControllerWebApp.war/untitled2.jsf @9,73 action="#{reportBean.userDefinedReport}": java.lang.LinkageError: loader constraint violation: loader (instance of net/sf/jasperreports/engine/util/JRClassLoader) previously initiated loading for a different type with name "org/codehaus/groovy/runtime/callsite/CallSite"

I've seen several posts about this error, saying that there might be more than one reference to the same jar, or two jars imported with the same dependencies/contents. So here is the list of jars i use in my app:

• groovy-all-2.0.1

iText-2.1.7.js2

jasperreports-5.1.0

jasperreports-fonts-5.0.4

poi-3.7 poi-ooxml-3.7

commons-io-2.4 (plus some other commons-* jars not related). These are the same i've used when the app was running, plus i've used Jasper before, and never got this error. Please help!

Thanks in advance.

Resolved by changing the report language property from Groovy  to Java.
