In Eclipse IDE it can run, but when I export it I got an error. Someone that can help me with this?

Answer 1

The org.eclipse.equinox.launcher plug-in is missing from the build (or possibly it is present but has the wrong version).

The configuration of plug-ins included in the RCP is separate from the configuration for the plug-ins used when you test your RCP from within Eclipse.

If you are using a '.product' file for the RCP go to the 'Contents' tab in the .product file editor and click the 'Add Required' button to add all the required plugins to the product. For a normal RCP there should be something like 100+ plugins in the contents list. Then rebuild the RCP.

In the above I am assuming you are using a 'plug-ins based' product configuration.
