Here is a full Ant build script which you can use with OpenLaszlo 5.0 (haven't tested with older versions).

Put the build script into a subfolder of $LPS_HOME (OpenLaszlo server home) called testapp. Create a subdirectory LZX, with an OpenLaszlo canvas application called testapp.lzx. I've added an image resource into the subfolder resources to test if resources are packaged correctly into the SOLO compiled application folders.

└── testapp
├── build.xml
└── lzx

Got into $LPS_HOME, and run "ant build". The build process should run through, and you should have the resulting folder structure:

The build process has generated three versions of the OpenLaszlo app: SWF with debug, DHTML/HTML5 with and without debug mode enabled. All JavaScript and SWF files have a timestamp attached, which means a new version of the application will not be pulled from the browser cache.
