MicroEmulator

J2ME Device Emulator is pure Java implementation of J2ME in J2SE.
It allows demonstrate MIDlet (MIDP/CLDC) based applications as a
standalone Java application or as web browser applet.

Context:
    1. Running application
    2. Applet config
    3. Building MicroEmulator from sources

Requirements:
 - J2SE 1.4+

There are two methods of running apps in emulator:

1. As an application:
a) java org.microemu.app.Main (MIDlet application main class)
or, java org.microemu.app.Main (MIDlet jad file)

 - microemulator.jar must be in CLASSPATH

b) java -jar microemulator.jar (MIDlet application main class)
or, java -jar microemulator.jar (MIDlet jad file)

 - (MIDlet application main class) parameter is optional, if used MIDlet
   application jar file must be in CLASSPATH,
 - (MIDlet jad file) must have .jad extension,
 - for Nokia UI support include nokiaui.jar to the CLASSPATH,
 - for Siemens API support include siemensapi.jar to the CLASSPATH.


2. In applet:

Preparing applet version of MIDlet should be done by selecting Save for Web menu item from File menu
in standalone MicroEmulator application. During that process additional MIDlet bytecode modification 
is performed in order to satisfy some compatibility issues running Java ME code inside Java SE. 

Produced html code:
<applet code="org.microemu.applet.Main"
		width=226 height=471 archive="microemu-javase-applet.jar,(MIDlet application jar)">
	<param name="midlet" value="(MIDlet application main class)">
</applet>

 - for Nokia UI support include nokiaui.jar to the archive attribute,
 - for Siemens API support include siemensapi.jar to the archive attribute.

There is additional parameter in applet definition tag if you want start applet
with another device than default:
  <param name="device" value="({device class name} | {device.xml file location})">
    eg. minimum phone included in distribution has
        org/microemu/device/minimum/device.xml

and remember to include new device jar into applet archive tag
    eg. minimum phone included in distribution has
        minimum.jar

Example for SimpleDemo MIDlet, Nokia UI support and Minimum device:
<applet code="org.microemu.applet.Main"
		width=157 height=285 archive="microemu-javase-applet.jar,nokiaui.jar,minimum.jar,simpledemo.jar">
	<param name="midlet" value="org.microemu.midp.examples.simpledemo.SimpleDemo">
	<param name="device" value="org/microemu/device/minimum/device.xml">
</applet>

Example for SimpleDemo MIDlet and Minimum device with Mouse and color:
<applet code="org.microemu.applet.Main"
		width=157 height=285 archive="microemu-javase-applet.jar,minimum.jar,simpledemo.jar">
	<param name="midlet" value="org.microemu.midp.examples.simpledemo.SimpleDemo">
	<param name="device" value="org/microemu/device/minimum/device-color.xml">
</applet>

Example for SimpleDemo MIDlet and Large Skin:
<applet code="org.microemu.applet.Main"
		width=292 height=618 archive="microemu-javase-applet.jar,large.jar,simpledemo.jar">
	<param name="midlet" value="org.microemu.midp.examples.simpledemo.SimpleDemo">
	<param name="device" value="org/microemu/device/large/device.xml">
</applet>


3. Building MicroEmulator from sources

  We are using maven2 to build project

  To build project you need this environment variables:
  JAVA_HOME, SWT_HOME (to build swt module) and WTK_HOME to compile and test MIDlets

  To create Eclipse projects run:
    mvn eclipse:clean eclipse:eclipse -DdownloadSources=true

  To run build without tests:
    mvn -Dmaven.test.skip=true
