问题
I been looking around and at sources like this one they say that a Midlet can invoke another if they are in the same suite, or if they are in the same namespace and in the same jar file.
I do not understand what a Midlet-Suite is?
Also after searching through the web I did not find any documentation or code examples for One Midlet invoking another Midlet.

The other replies are pretty much taking care of your questions about MIDlet Suites but I would suggest reading the MIDP specification to get the information first-hand:
http://www.jcp.org/en/jsr/detail?id=118
On recent phones (Series60 5th edition from Nokia Sony-Ericsson and Samsung, other Sony-ericsson phones), the Content Handling API (CHAPI) is supported for MIDlet-to-MIdlet invocation. That's JSR-211. You can read the specification for that here:
http://www.jcp.org/en/jsr/detail?id=211
The latest version of the Nokia Java Developers Library will contain more explanation:

The latest JavaME SDK will contain CHAPI code examples:

Edit: CHAPI is also available on non-Symbian Nokia phones from Series 40 5th Edition, Feature Pack 1 onward, according to the Nokia Java Developers Library. You can find which nokia phone is running which version of Series40 at:

A MIDlet suite is basically the JAR file. There are many J2ME applications that contain several MIDlet classes in the jar, see some of Sun's examples that come with WTK.
Edit: There's an example called MMAPIDemos that comes with sun's WTK that uses 3 MIDlets in one suite.

You can try PushRegistry as a more generic way. You should be able to launch MIDlets from other suites as well. Try this link for more information.
