create a .war file from gwt-project

Question

How do I create a .war-file from my gwt-project in eclipse?

Answer 1

One can also use webAppCreator to generate Ant build file.

webAppCreator ships with GWT SDK and also with Eclipse GWT Plugin. First locate GWT plugin directory

find $HOME/.eclipse/ -name "*gwt*sdk*"

this will output GWT plugin dir path. This dir has gwt dir something like gwt-2.4.0. WebAppCreator will be in this dir. Set this dir as GWTSDK_HOME.

export GWTSDK_HOME=/home/m/.eclipse/org.eclipse.platform_3.7.0_1364963873/plugins/com.google.gwt.eclipse.sdkbundle_2.4.0.v201201120043-rel-r37/gwt-2.4.0

make webAppCreator executable

chmod 755 $GWTSDK_HOME/webAppCreator

Now create a project using webAppCreator in some temp dir.

$GWTSDK_HOME/webAppCreator -out fins in.m.fins.Fins

in.m.fins.Fins is the module name. This has to match with your project's gwt.xml in Eclipse workspace. If your gwt.xml is src/in/m/fins/Fins.gwt.xml then module name should be in.m.fins.Fins

-out fins will create the project and build.xml in fins directory. Copy generated build.xml file to your project in Eclipse workspace.

Run war target in Eclipse Ant Window to package your project as war
