forumdata ,
Sorry that you are seeing this issue.
1. From where did you move the application to MyEclipse Blue 10.1 ? Is it from any other IDE or from previous versions of MyEclipse ?
2. Can you please check if the relevant jar file is present in your project for the import to work ? It may be possible that the said jar is not exported while moving the application.
You can download the relevant jar from here :

Let us know how it works for you.
