There is a special Docker image for developing on Java for Palm OS (v5).

Image based on:

• Java 1.5
• Sun Java Wireless Toolkit (WTK) 2.5.2-01

Some files should be added to cloned repository by hand:

• JDK 1.5 for Linux (i586). Filename should be: jdk-1_5_0_22-linux-i586.bin. This file should be copied to the root of git-repository. MD5SUM should be: df5dae6d50d2abeafb472dde6d9a17f3.
• Sun Java Wireless Toolkit. Filename: sun_java_wireless_toolkit-2.5.2_01-linuxi486.bin. It should be compiled to the root of repository. MD5SUM should be: 6b70b6e6d426eac121db8a087991589f. If md5sum differs — then byte-patching of install package will fail! This action necessary to automatically accept license and install files without any input from user.
• jartoprc files should be extracted from this archive and copied into jar2prc/ catalog. Expected result:

  jar2prc/
  ├── bin
  └── lib
      └── jclFoundation10
      

docker compose build

./run-dev-env.sh

./stop-dev-env.sh

Some catalogs will be mounted from root directory in cloned git-repository to /home/devel/ catalog inside docker container.

j2mewtk

WTK projects will be stored in this catalog

jar2prc

jartoprc Windows application

sdcard

SD-card attached to Palm emulator will be mounted here
