JavaParty Reference
The JavaParty Compiler
The JavaParty compiler is derived from the Generic Java compiler and
therefore accepts the same options plus some JavaParty specific
options. The JavaParty compiler is invoked with the following command
line:
- jpc options* source-file.java+
You can specify options as described
below followed by a list of Java or JavaParty source
files.
- -d output-directory
Specifies the output directory for compiled class
files. You must specify this option when compiling
classes that reside inside a package. - -classpath application-class-path
Path for loading classes referenced from
source files being compiled. Alternatively, you can set the
CLASSPATH environment variable. - -stubdebug
The JavaParty compiler automatically
generates stubs and skeletons for remote classes. If you use
KaRMI, the compiler generates debugging code that traces
remote method calls via debugging messages. - -help
Prints all supported options.
Unix only: Invite a Java party
jpinvite [-cp|-classpath <application-class-path>]
[-D<property-name>=<value>]*
[-X<virtual-machine-option>]*
[-J <argument-passed-directly-to-Java>]*
[-nodenames <comma-separated-list-of-hosts>
|-nodefile <PBS-style-node-file>]?
[-frontend]?
[-purify]?
<class-name> <class-arguments>*
JPInvite spawns a Java virtual machine on all specified hosts,
invokes your application class and shuts down the environment after
the main() method returns.
The Java specific options are passed to each participating virtual
machine. The script assumes that either the cluster has a common
network file system, or the file system layout of each node is
identical to the layout on the invoking machine.
-
-cp <application-class-path>
-classpath <application-class-path>
-
Set the class path for the application consistent on all
participating virtual machines. Assumes, all computing nodes have
a common network file system or have at least the same directory
layout.
-
-D<property-name>=<value>
-
Set a system property consistent on all participating virtual
machines.
-
-X<virtual-machine-option>
-
Set a non-standard option on the Java virtual machine.
-
-J <argument-passed-directly-to-Java>
-
Pass some other option directly to the underlying Java virtual
machine.
-
-frontend
-
Use an extra front-end virtual machine for invoking a local main
class. This front-end virtual machine does not become part of the
dirstributed environment and can be used to start a local GUI.
To get X11 forwarding, for all your nodes, set the JPQ_RSH
environment variable accordingly.
-
-purify
-
Purify the console output of the virtual machines spawning the
distributed environment. This option prevents that lines of
output from different virtual machines are merged. Additionaly,
each line of output is prefixed with the number of the virtual
machine that printed it. With this option, all output is
redirected to standard output.

Windows only: The JavaParty Runtime Manager
The runtime manager is the central instance in a JavaParty
environment. It keeps track of registered virtual machines and manages
information about loaded remote classes.
- jprm option*
Starts the JavaParty runtime manager on the
current machine.
- -code runtime-manager-access-code
The JavaParty virtual machines use
multi-cast to look up an active JavaParty environment for
registration. Each JavaParty environment must use an unique code
to make sure that a virtual machine registers at the right
manager.
If no code is specified, your user name is used as default
value. Therefore, only need to choose another code, if you want to
start more than one JavaParty environment.
- -port runtime-manager-port
Chooses an alternate port for exporting
the registry (for details consult the RMI specification).
You only need to use this option, if you want to start more than
one runtime manger on the same host, or if the default port is use
from another application.
Note: If you are using JavaParty for KaRMI, you also
have to adapt the KaRMI configuration (see the KaRMI).
- -verbose
Show what the runtime manager is doing.
- -debug
Show information about remote classes
loading.
Windows only: The JavaParty Virtual Machine
- jpvm option*
Start one node of the distributed
environment. The execution of a JavaParty program takes place in
one ore more virtual machines.
- -code runtime-manager-access-code
See the runtime manager. - -host runtime-manager-host
Only register the virtual machine on a
runtime manager running on the specified host. By default the
runtime manager is looked up using multi-cast. - -port runtime-manager-port
See the runtime manager.
If you specify the -host and -port options,
no multi-cast is used.
Windows only: Application startup
- jp jp-args* class-name arguments*
Invokes the applications main class. See
JavaParty virtual machine for options accepted for
choosing the runtime manager. The command returns when the main
method of the application is completed.
