Hi there,
The following java program creates an xmi output file called tpfOut.xmi. I am just wondering, if someone can give me a clue how to create/capture java objects instead of xmi output?
The program is:
package org.eclipse.m2m.atl.launch.files;
import java.io.IOException;
import java.io.InputStream;
import java.net.URL;
import java.util.HashMap;
