java like a CGI

[Yoni]

Hello,

I have a java program that I want to run in my cgi-bin directory.
My hosting plan does not support java.
If I can compile my java class into binary code (embedding a jvm) I should be able to use that program like a cgi.

Any suggestion? :)

I would like to avoid to translate that stuff in python or changing my hosting plan :-)

thank you!

Yes, get a hosting provider that supports Java. I don't think the
compiled-Java stuff works, strictly speaking.

Amazon EC2 instances work fine for Java, a full container like JBoss can
run easily on a micro instance. And micro instances are free for the
first year if you're a new customer.

I don't want to sound like an advert for Amazon EC2, but it's a decent
deal if you're just starting out.

Running Java as a CGI isn't a great idea in the first place. Most "web"
based Java programs are called "webapps", and they use "servlets". A
servlet is basically a java program which acts as a web server directly,
so the Java program doesn't need to "start up" every time a user request
comes in.

I have a java [sic] program that I want to run in my cgi-bin directory.

For God's sake, why?

Switch hosting plans or use a different language than Java.

Don't.

You want a lot of contradictory things.

Why don't you want to translate the code or change hosting plans?

Which is more work - banging together a Java program to use like it isn't Java,
or switching to a host that lets you use Java?

Over the long haul?

Really?

Understatement.

Not exactly. It is a Java class that is invoked by the web server, itself a Java
program.

Step back and decide what you really want to accomplish. You don't want to
create a whole bunch of moreau hybrids whose components collide with
each other.

One assumes, given your question, that you don't expect to serve more than a
few dozen requests per minute.

Yes, though I didn't think that level of detail was useful for the OP.

Good advice.

Find a new ISP or set up a little Linux server and host it yourself on
your home LAN. They will be even less happy about you running
arbitrary apps.

You can try to use gwt (https://developers.google.com/web-toolkit/) to compile your original program into an equivalent javascript/html page
