I have a java applet that has some rather extensive code for
making certain calculations.  Is there any way to execute java
code within Delphi 4?  I was thinking of starting an invisible
Netscape or Explorer browser and making an end run that way.
It would be much easier, however, if there was a component or
some other way.

  Thanks.

Hi !

1. you could launch a separate program, calling "java MyClass" to
execute the java Program in a dos shell. I think starting netscape or IE
is a bit too much overhead here... Of course communication between the
java program and your delphi app is a problem then. So you might:

2. Deploy the java Class as a COM Component (you need MS J++ for this
job) and use this newly created activeX component in your Delphi App.
If this sounds too simple you could try

3. Deploy your java class as a CORBA Object (you might use JBuilder for
this) an access it from your Delphi app via an ORB (you could use
Visibroker which comes with Delphi and JBuilder Enterprise Editions)
