ceylon-jboss-loader

Module Loader for JBoss and Wildfly that allows Ceylon modules in web applications

Sample Web Application

See https://github.com/dgwave/ceylon-jboss-loader/tree/master/src/test/resources/webapp

  • The Ceylon module containing your Ceylon servlets needs to be defined in WEB-INF/jboss-deployment-structure.xml as <resource-root path="WEB-INF/lib/hello.world-1.0.0.car"/> or any other path within your WAR.
  • For now, immediate dependencies of your servlet Ceylon module need to be defined similar to <module name="ceylon.html" slot="1.0.0"/>. Transitive dependencies are handled automatically. With an upcoming Wildfly subsystem that we are developing, this will not be necessary.

Adding Ceylon Add-on Layer to Wildfly 8.0

  1. Create Ceylon add on layer by creating directory wildfly-8.0.0.Final/modules/system/add-ons/ceylon
  2. Copy the contents of your deployment-ready Ceylon distribution repo directory into this Ceylon add-on layer directory
  3. Copy the contents of your deployment-ready Ceylon SDK and any other Ceylon or Ceylon-ized Java modules into this same Ceylon add-on layer directory
  4. Build the Ceylon loader (this project) with mvn clean package
  5. Copy ceylon-loader-0.5.jar from the target directory into the Ceylon add-on layer under the com/dgwave/car/loader/main sub-directory
  6. Copy src/main/resources/module/main/module.xml into the same directory as (5) above

Enabling in Wildfly 8.0 Server embedded in Eclipse IDE

  1. Open Wildfly Runtime Server configuration (Needs JBoss Studio or Wildfly server plugin)
  2. Click on Open Launch Configuration and select the Classpath tab
  3. Under User Entries, find ceylon-loader-0.5.jar where you copied it into the Ceylon add-on layer
  4. Select the Arguments tab and add this at the end of the VM Arguments box: -Dboot.module.loader=com.dgwave.car.loader.CarModuleLoader

Enabling Wildfly 8.0 Server in Windows

  • For Windows: Add this at the very end of your standalone.conf.bat or domain.conf.bat:
set "JAVA_OPTS= -classpath %JBOSS_HOME%\jboss-modules.jar;%JBOSS_HOME%\modules\system\add-ons\ceylon\com\dgwave\car\loader\ceylon-loader-0.5.jar -Dboot.module.loader=com.dgwave.car.loader.CarModuleLoader %JAVA_OPTS%"
  • For Windows: Replace this line in standalone.bat or domain.bat. This is supported as JBoss Studio works with this mechanism:
-jar "%JBOSS_HOME%\jboss-modules.jar" ^

with

org.jboss.modules.Main ^

Enabling JBoss/Wildfly Server in Unix/Linux

Very similar to above, but still to be tested. TBD
