I ran into the same exact error and was initially misled by the "product not found error message". After tracing the stacktrace and the Eclipse source code I realized that when I dropped my Application.e4xmi into the ui plugin project I hadn't added it to the build.properties file so that it would get packaged in the jar. Once I did that it worked as expected.

I was facing similar problems, when following the tutorial from vogella

Make sure the plugin defining your product "myapp.product" is also included in the product configuration. So, if your product configuration is based on features, you need to add the "myapp.product" plugin inside a feature. Otherwise, it is not part of the packaging.

Product myapp.product could not be found is the key message here - your exported product doesn't seem to contain your product definition (perhaps the plugin is missing). The crash is caused because the product couldn't be found.

Make sure that your xxx.product file contains all your plugins plus all the Eclipse RCP plugins that they depend on (you can use the 'Add Required' button to work this out).
