Jbpm sample project error

[aneesrahman]

Hi I'm new to Jbpm, when I try to run the sample jbpm project (ie. simple "helloworld" project) I'm getting this error on console. I've imported almost all jar files those which are required for jbpm project. But still I'm facing this issues. Can anyone help me to fix this error asap.

Hi,

the exactly same error was solved in a previous post. Here's the link:

Unable to run example project as Java application

Maybe the steps done there will help you.

It seems you are running a version of jBPM & Drools that did not yet have support for JDK7?  Try to make sure you have are using a recent version.  If you are using Eclipse and using a jBPM or Drools classpath container, try configuring your runtime to a newer version (by removing your old runtime in Eclipse preferences and for example downloading the new -bin artefact and creating a new runtime based on that folder).
