There is however one major problem with using GWT hosted mode under maven – it’s the native hosted mode libraries (dlls) and the way Google chose to implement them – a couple of GWT hosted mode dlls need to be located _in the same_ folder where the gwt-dev-windows.jar is present. And thus the hack below to copy the dlls into such location. And no, -Djava.library.path won’t work!!! Unfortunately, this setup will only work with the local maven repositories and will completely fail if you try this trick with the remote maven repos (unless I’m unaware of some other hack).

cmd /c mvn install:install-file -DgroupId=com.google -DartifactId=gwt-dev-windows -Dversion=1.5 -Dpackaging=jar -Dfile=C:/java/gwt/gwt-windows-0.0.0/gwt-dev-windows.jar -DgeneratePom=true -DcreateChecksum=true

One more thing, I find that Jetty’s manual refresh mode available in maven-jetty-plugin version 6.1.12.rc2+ be very handy when developing stuff with GWT and java/jetty/spring. I can edit my GWT files all I want and only reload server stuff when I indeed changed something in the server side java code (rather than the Java code that gets compiled into javascript by GWT but leaves in the same maven project). Here is my jetty maven plugin configuration that I use for the -noserver development, in case you are interested

<plugin>
<groupId>org.mortbay.jetty</groupId>
<artifactId>maven-jetty-plugin</artifactId>
<version>6.1.12.rc2</version>
<configuration>
<reload>manual</reload>
<scanIntervalSeconds>10</scanIntervalSeconds>
<stopKey>foo</stopKey>
<stopPort>9997</stopPort>
<webAppConfig>
<contextPath>/</contextPath>
<defaultsDescriptor>src/main/servers/jetty/dev/webdefault.xml</defaultsDescriptor>
</webAppConfig>
<scanTargetPatterns>
<scanTargetPattern>
<directory>src/main/webapp/WEB-INF</directory>
<includes>
<include>**/*</include>
</includes>
</scanTargetPattern>
</scanTargetPatterns>
</configuration>
</plugin>

Anyway, hopefully this was useful for some of you and look forward to any comments.

Pinned Panel – a neat sliding panel type widget with the panel capable of rolling from a side of the screen:

9) Progress bars – the oft requested GWT feature but for some reason missing from the core GWT:

10) Slider Bar – a powerful and sophisticated GWT slider implementation:

11) Spinners – anything non-visual that can spin, can be spinned . pretty interesting, IMO:

12) Style injector/Immutable Resource Bundle – injecting CSS into GWT compilation result using annotations, and writing code within CSS to customize for different browsers or what not.

13) YouTube widget (or any Flash object) – embed YouTube videos or whatever other objects using GWT.
