Wimpy,
Sorry that you are seeing this issue.
Can you please do the following steps :
1. Can you please update to MyEclipse Blue 10.6 which is the latest version? You can update the current 10.0 to 10.6 from the MyEclipse Configuration Center > Software > Updates Available > MyEclipse Enterprise Edition 10.6. Apply the changes , follow the wizard and restart the IDE when it prompts to.
Alternatively you can download the MyEclipse Blue 10.6 installer from here :
https://www.myeclipseide.com/index.php?name=Recommend_Us&req=Download&version=MEBlue
You can choose to install 10.6 to a different location without uninstalling 10.0.
2. Right click on the EAR > Properties > MyEclipse > EAR. Uncheck the option ‘Run EJBDeploy Tool’. If the EAR project has EJB 2.x as well, then you need to manually run the MyEclipse EJB Deploy tool. Right click on the EJB 2.x module > MyEclipse > Run EJB Deploy. Now try debugging.
3. If you are seeing any issues, please copy paste the entire error message here along with the contents of the deployment.log.
Let us know how it works for you.
