GWT Studio provides the following features:
- actions to create different elements of GWT application
- GWT specific inspections and quick fixes
- integration with GWT compiler
- specific run configuration for starting and debugging GWT applications from IntelliJ IDEA
- basic refactorings
- GWT in the hosted mode
- "Rename" refactoring is aware of GWT
- "Go To Declaration" action, "Find usage" action and completion for GWT specific references
GWT Studio roadmap for version 1.0 includes:
- integration with HTML editor to support completion and validation of references to GWT resources (e.g. modules) from HTML files.
- much more inspections, quick-fixes and intention actions
- JScript -> native
- html -> GWT source
- check for supported JDK subset
- Visual Designer (low priority task)
Current version of GWT Studio is 0.1.4 It is included EAP builds of IntelliJ IDEA 6.0 (Demetra) starting from build #5333.
GWT Studio is still on the early research stage but most probably, it will become core function of IntelliJ IDEA 6.0 (Demetra).
- GWT internationalization support
- support for packaging files generated by GWT compiler into JavaEE application
Actions are used to generate GWT elements such as entry points, remote services, etc. Each action suggests to configure GWT support if necessary and adds GWT libraries into module classpath.
New GWT Module
Creates GWT application template inludingincluding:
- .gwt.xml module file
- EntryPoint class
- .html page
- .css file
New GWT Entry Point
Creates GWT entry point template and performs the following operations:
- generates a class derived from EntryPoint
- adds a necessary <entry-point> element to the .gwt.xml module file
New GWT RemoteService
Creates GWT remote service template and performs the following operations:
- generates an interface derived from RemoteService
- creates an async asynchronous version of the interface
- creates RemoteServiceServlet implementing the interface
- adds necessary <servlet> element to the .gwt.xml module file
New GWT Serializable Class
Creates new class derived from IsSerializable with no-argument constructor.
Creates sample application which send a text message to the server and display the responce. It can be used as simple starting point.
Inspections with quick-fixes
Works under test sources roots. Creates new class derived from GWTTestCase.
New GWT UiBinder class and ui.xml file
Creates new *.ui.xml file with the corresponding Java class
"Go to declaration", "Find Usages", "Rename" actions, completion and highlighting works for GWT specific references in the following places:
- parameters of methods UIObject.setStyleName, addStyleName, removeStyleName
- parameter of RootPanel#get method
- @Key annotation
- <inherits> tag in .gwt.xml file
- the return statement in "getModuleName" method in classes derived from GWTTestCase
- parameter of ServiceDefTarget#setServiceEntryPoint method
- @RemoteServiceRelativePath annotation
- <meta> and <script> tags in GWT html file
- tags and attributes in ui.xml files
- @UiHandler annotation
GWT Studio have inspections to report the following problems:
- RemoteService-derived interface is not synchronized with its
- asyncronous version
- Asynchronous version of RemoteService-derived interface is not synchronized with the original interface
- Type of parameter or return type of method in RemoteService-derived interface is not
- GWT Remote service is not registered as a servlet in web.xml
- Classes not from JRE emulation library (and not from client code of inherited modules) are used in client code
- Class marked as serializable contains non-serializable fields
- Style name used as parameter of
- "addStyleName" or
- "setStyleName" is not presented in CSS file
Special Run/Debug configuration of GWT application
GWT compiler used during IntelliJ IDEA "make"
- Localizable interface is not synchronized with the corresponding .properties file
- Interfaces derived from Constants contains methods with parameters
- Deprecated @gwt.key JavaDoc tag usages
- Deprecated @gwt.typeArgs JavaDoc tag usages
- AsyncCallback class is used without type parameters
- ServiceDefTarget.setServiceEntryPoint is used instead of @RemoteServiceRelativePath annotation
- Usages of event listeners classes deprecated in GWT 1.6
- Inconsistencies between fields with @UiField annotation and 'ui:field' attributes in ui.xml files
- Wrong signatures of @UiHandler methods
Each inspection suggest a quick-fix to resolve the corresponding problem.
Integration with I18n support
- navigation from method of interface to corresponding property (using icon on an editor gutter or "Go to implementation" action)
- inspection to report inconsistencies between interfaces and property files (with quickfixes to create missing property or method)
- "Rename" refactoring for properties, methods and interfaces renames corresponding methods, properties and properties-files
- "Internationalize" action in IDEA is aware of GWT and automatically creates corresponding methods in interfaces
GWT-related settings are available via GWT Facet (Project Structure | "Modules" item | A module node in the tree | "GWT" node)
Packaging into JavaEE application
An output of GWT compiler can be automatically copied to an artifact on make. Just include the GWT Compiler Output element in the artifact layout. An individual relative output path for each GWT module can be specified in GWT Facet settings as well.
Run/Debug GWT application in the hosted mode
Use "GWT configuration" to run/debug a GWT application in the hosted mode. Also "Run" action is available in the popup menu for GWT entry point classes and html files allowing to run a GWT application the hosted mode immediately. If AppEngine is used in the project GWT configuration allows to specify AppEngine Dev Server as a target server.
GWT Studio comes bundled with IntelliJ IDEA starting from IDEA 6.0.
