JDK and NetBeans
Installed in $HOME/bin/jdk1.6.0_25 and $HOME/bin/netbeans.
Will use the ant coming with NetBeans.
Set .bash_profile:
export JAVA_HOME
export ANT_HOME
export PATH
On Fedora 14, install compat-libstdc++-33 for the hosted mode to work.
Run Example Hello
cd work/gwt-linux-1.7.1/samples/Hello
ant hosted
Run Example Hello Out-of-the-tree
cd work
mkdir build
cp -a gwt-linux-1.7.1/samples/Hello ./build
cd build/Hello
Edit build.xml to change gwt.sdk pointing to ../../gwt-linux-1.7.1
ant hosted
Run Example Hello Out-of-the-tree in NetBeans
Create a java project with existing code using the same work/Hello
directory for the project. Netbeans will add two files to Hello
directory. Ignore them. Use file window in Netbeans, right click
on build.xml node, and run build or hosted target. The ant inside
Netbeans will just build everything as if you are doing it from
command line.
To have the sample Hello to build please add the gwt-user.jar
to the library. To have the sample Showcase to build please
add also gwt-dev-<os>.jar, because the java code need to generate
also the source code into the HTML pages.
Run on Windows 64bit
Install JDK 64bit.
Install Netbeans JavaSE.
Install JRE 32bit.
Edit build.xml:
[1] "gwt.sdk" same as mentioned above.
[2] Change the target "java" under "hosted" to have an extra value for
property jvm: jvm="C:\\Users\\whoami\\Programs\\jre6.32\\bin\\java".
The path is the jre 32bit installation.
