WTK25 question: Create Obfuscated Project

Question

Hi all,
I'm developing a MIDlet that enables communication between two mobiles. I test it out using the WTK25 (version Version 2.5 for CLDC Beta) I downloaded from Sun. I'm running the program partly on the command line and partly in WTK25.
I observed strange behaviour. When I build the project using Project > Package > Create Package and run it from the command line, I get a NullPointerException. Most of the time A NullPointerException is my fault as developer. I try to use an object I did not instantiate.
But when I build the project using Project > Package > Create Obfuscated Project I can run my MIDlet without a problem. I use the proguard.jar for obfuscating. I tried to use the retroguard.jar but had other problems with it.
Anyone care to comment on that?

Hi Scott,
No, this choice only impacts the version of the Web Deployment Descriptor (web.xml).
When you create your workspace from the Create Application wizard by selecting the "Web Application [JSF, ADF BC]" template, we suppose that you work with a J2EE 1.4 application (the current version).
If for some reasons, you have to work with a J2EE 1.3 version, f.ex. because you have to use JSTL 1.0 (see "JSTL 1.0 in JSP 2.0 Pages" in http://blogs.oracle.com/Didier/2006/03/20#a10), then you should create your Web Project and select "Servlet 2.3\JSP 1.2 (J2EE 1.3)".
Later, you have the option to upgrade your Deployment Descriptor to Servlet 2.4\JSP 2.0 (option in the right-click menu on the web.xml).
