Download the source distribution of Opal2 for installation from here, if you don't have the appropriate version already.
Extract the downloaded tarball using the GNU tar utility (or other similar utilities for Windows), as follows:
tar zxvf opal-ws-$VERSION.tar.gz |
This should create a new directory called opal-ws-$VERSION/ where all the sources are expanded. Henceforth, we refer to this directory as OPAL_HOME.
A generic Java client for Opal services is implemented by the GenericServiceClient class located in $OPAL_HOME/src/edu/sdsc/nbcr/opal. It lets you run any application exposed as an Opal service, and retrieve its status and outputs.
To compile the client, perform the following step from inside the $OPAL_HOME directory.
$ANT_HOME/bin/ant jar |
