Use the javac compiler from the Java SE development kit to compile Java source files. You can use the existing Java ME Platform SDK project directory structure. Use the -bootclasspath option to tell the compiler to use the MIDP APIs, and use the -d option to tell the compiler where to put the compiled class files.

The following example demonstrates how you might compile a MIDP 2.0 application, taking source files from the src directory and placing the class files in the tmpclasses directory. Newlines have been added for clarity.

javac -target 1.3 -source 1.3 
   -bootclasspath ../../lib/cldc_10.jar;../../lib/midp2.0.jar
   -d tmpclasses
   src/*.java
