Development

Getting Started

Each resource type can have its own GWT code, e.g.the policy manager resource type

src/resources/policymanager/src-gwt

One can build the GWT source by running the gwt:compile ant target, e.g.

./build.sh -f src/resources/policymanager/build.xml gwt:compile

whereas please make sure that the resource type build file imports the GWT-RT.build.xml file instead the regular file resource-type.build.xml

The gwt:compile target compiles the GWT Java code to cross-browser Javascript code and saves it within the htdocs directory of the corresponding resource type, e.g.

src/resources/policymanager/htdocs/org.wyona.security.gwt.accesspolicyeditor.AccessPolicyEditor

Configuration of GWT version

The GWT version can be configured per resource type within src/build/GWT.build.properties, e.g.

src/resources/policymanager/src/build/GWT.build.properties

Speeding up development

By default the GWT source is compiled for all GWT-supported browsers. While developing this can be overridden per resource type within the module configuration (property user.agent), e.g.

src-gwt/java/org/wyona/security/gwt/accesspolicyeditor/AccessPolicyEditor.gwt.xml

There are also some more flags within src/build/resource-types/GWT-RT.build.xml which can be set and help speeding up development, such as for example the -draftCompile fiag, but please be aware that these flags depend on the GWT version you are using (see above: Configuration of GWT version).

Each src-gwt directory can contain an optional build properties file, e.g.

src/resources/policymanager/src-gwt/build.properties

containing the module names, e.g.

module.name=org.wyona.security.gwt.accesspolicyeditor.AccessPolicyEditor

which helps to speed up development, because only this specific module will be compiled. But one can have several modules per src-gwt (*.gwt.xml) directory and if one wants to compile all at once, then one should remove such build.properties files.
