Android: class NOT FOUND in Eclipse-built-in external bank, but FOUND in Netbeans-built

This is a continuation of this question: "android cannot find class from external jar"

I have an Android project in Eclipse that uses an external JAR. The JAR is extremely simple: it contains a toy class that calculates the square of a number and returns the result as a String.

Bad . If I create a JAR in Eclipse by creating a regular Java project with a class, then exporting it to a jar file and finally adding this JAR to the build path of the Android project, I get a runtime exception that this class cannot be found.

GOOD . If I create a JAR in Netbeans and add that JAR to the build path (in Eclipse), everything will work fine.

I really unzipped both banks to compare the contents. There seems to be a difference in the .class files, but they are not human readable, so I cannot get further promotion.

So my q is this : what can I change in the Eclipse export to make the external jar “good”? What makes NB correct if Eclipse does wrong? Or am I just resorting to creating all my external JARs in NB?

thanks

If your problem is with ADT 17, the easiest solution is to create the libs directories in your project and copy the jar into it. see link
