javax.print in ejb

I am writing something like this in my session bean, but PrintServiceLookup.lookupDefaultPrintService() cannot find any print service.

When I write the code separately in the java file, it can get all the print service. So I guess it has to do with the ejb container.

Can I use javax.print or java.awt api in ejb?

Thanks & Regards

You can use the print service. But why you'd want to is another matter. The only printers you can get access to will be those visible to your application server machine, and not your client.

AWT however you can't use. Again, why would you want to?

Thanks.

I want to do printing on the server side, that is, printing using session bean. I have tried crystal clear report engine, but it prints (using java.awt.printjob) in servlet engine; but i only want to do printing in ejb container. I am looking for solutions ... Any suggestion? Thanks & Regards
