How to import another .eap file?

[mmo]

In order to be able to refer to standard Java types I imported the Java rt.jar file into an new, i.e. previously empty, class model an saved that as a separate Java_1.7.eap project file). This import ran well over an hour!

But now I am stuck: how do I import or include or refer (whatever EA supports) that Java class model into my actual project, so that I can refer to those classes?

The manual only talks about importing .java source files or .jar files into an existing project, but I don't want to have to re-un this hour-long import of rt.jar for each new project! Can you advise, please!

You could export the jar import via XMI and re-use it via XMI import in other repositories. That should be quicker.

Alas, it's not quicker - and it doesn't work.
First, the export ran for maybe an hour and then it crashed...
So, no joy!

Other ideas to import the standard Java API into a project (classes only, no diagrams or such)

The only other alternative is to clone the one containing the import with Project Transfer and then move in the "small own rest".

Seems to be indeed the only alternative...

In a second attempt the export ran for >4 hours, came through (surprise!)  and produced an XML file of  320+MBs! I didn't even try to import this beast, yet. Probably that takes at least as long...

Has anybody an idea, how to generate and import just a subset of the Java rt.jar? Normally one doesn't really need the ENTIRE java runtime, just the "official" Java API (i.e. essentially java.* plus maybe javax.*).

Use any zip utility (E.g. Winzip, 7-zip) to extract the individual .CLASS files you want from the JDK (rt.jar) into a temporary directory and then import into EA using the "Import Source Directory" command.

do publish->export to XMI from one eap and save it to some file name.
 to import diagram from other eap in current eap, go to publish->import XMI to load the package/diagram from other eap which is exported above.
