Re: [Microemulator-users] Classloading changes in 2.0.1?

[Bartek T. <ba...@ba...>]

Hi,

Indeed, we changed classloading method in 2.0.1. Mostly because we
wanted to fix some core library incompapilities beetween Java ME and
Java SE and we started to use ASM bytecode intrumentation software for
that purpose.

Your example is a side effect of that change. However we designed new
classloader code to be compatible with MIDP packaging scheme
(jad/jar). Your example doesn't fit into that standard.

If you want to change that behaviour look into the following parts of
MicroEmulator code:

1. microemu-javase/src/main/java/org/microemu/app/Common.java
public static void openJadUrl(String urlString)
public static void openJadUrl(String urlString, MIDletClassLoader
midletClassLoader)
protected void loadFromJad(String jadUrl, MIDletClassLoader midletClassLoader)

2. microemu-javase/src/main/java/org/microemu/app/classloader/MIDletClassLoader.java
