Apache TomEE

Building

The Transformer is a project at the Eclipse Foundation, and is built using Gradle. To checkout and build from source, do the following:

git clone https://github.com/tbitonti/jakartaee-prototype
cd jakartaee-prototype
./gradlew assembleDist

This will produce a tar and a zip in the transformer/build/distributions directory.

Running

Unzip the resulting zip file, and add the bin directory to your PATH variable, and you should be able to run the transformer using the transformer script.

Running transformer -u will provide the usage information:

With an already built and extracted TomEE server, we can do some experimentation.

Rename the lib folder:

mv lib javaee-lib

Create a Jakarta EE lib folder:

mkdir jakartaee-lib

Translate each of the jars in the javaee-lib folder:

cd javaee-lib

for f in *; do transformer $f ../jakartaee-lib/$f -tr <path/to/rules/file>; done

See the rules section below for the rules file.

Symlink jakartaee-lib folder to lib:

cd ..
ln -s jakartaee-lib lib

You should now be able to start a Jakarta-ized version of TomEE. (Expect errors - these can be discussed on the list)
