Creates a process object, the process is NOT invoked at this point.
You should first set the process's parameters, and then call startJava.

<br></td><td align="right"><h3><strong>startJava</strong></h3></td></tr></table><p></p><p>
Invoke the JVM with the parameters that have been set. The Java process
will start after this call.
</p>
<A NAME="stopJava"></A><A NAME="ref4"></A><table width="100%"><tr bgcolor="#eeeeee"><td>void <strong>stopJava</strong> ()
<br></td><td align="right"><h3><strong>stopJava</strong></h3></td></tr></table><p></p><p>
Stop the JVM (if it's running).
</p>

<br></td><td align="right"><h3><strong>isRunning</strong></h3></td></tr></table><p></p><p>
Returns the status of the java Process- true if it's ok, false if it has died.
It calls KProcess::isRunning()
</p>

Used to specify the path to the Java executable to be run.

This will set the classpath the Java process will use. It's used as a the
-cp command line option. It adds every jar file stored in $KDEDIRS/share/apps/kjava/
to the classpath, and then adds the $CLASSPATH environmental variable. This allows
users to simply drop the JSSE (Java Secure Sockets Extension classes into that directory
without having to modify the jvm configuration files.

<br></td><td align="right"><h3><strong>setSystemProperty</strong></h3></td></tr></table><p></p><p>
Set a property on the java command line as -Dname=value, or -Dname if value is QString::null.
For example, you could call setSystemProperty( "kjas.debug", "" ) to set the kjas.debug property.

Arguments passed to the main class. They will be very last in the java
command line, after the main class.

Sends a command to the KJAS Applet Server by building a QByteArray
out of the data, and then writes it standard out.

Sends a command to the KJAS Applet Server by building a QByteArray
out of the data, and then writes it standard out. It adds each QString
in the arg list, and then adds the data array.
</p>

<br></td><td align="right"><h3><strong>slotWroteData</strong></h3></td></tr></table><p> <small>[protected slots slot]</small></p><p>
This slot is called whenever something is written to stdin of the process.
It's called again to make sure we keep emptying out the buffer that contains
the messages we need send.

<br></td><td align="right"><h3><strong>slotReceivedData</strong></h3></td></tr></table><p> <small>[protected slots slot]</small></p><p>
This slot is called when the Java Process writes to standard out. We then
process the data from the file descriptor that is passed to us and send the
command to the AppletServer
