Hi Janak, Thanks for advice, but when I write custom coder, I have problem how to put, for example JasperPrint object, to the IObjectOutputStream in metode writeObject, or how to get JasperPrint object from IObjectInputStream in metode readObject custom reader object.
JasperReports product has utilities JRLoader and JRSaver which work with streams, but those streams are java.io streams. ULC is not attached with those streams. Thence I tried put JasperPrint object directly to IObjectOutputStream Object through methode writeObject (JasperPrint implements Serialisable) and get it directly from IObjectInputStream object through readObject methode, but in this case, occures error: StackOverflowError. I tried it in DevelopmentRunner ULC 6.1.1. Source code for custom coder I attached with this mail. Thanks fo advice.

You will have to write a Coder for the class whose instance you want to send to the client as an argument to invokeUI() call. Please see sections 3.4.4 and 4.4 of the ULC Extensions Guide. Once you have written a Coder you will have to register it with the CoderRegistryProvider on the client and server. The CoderRegistryProviders are specified as parameters to the ULC client (Applet param or JNLP param) and ULC server (servlet param). For the DevelopmentRunner use setClientRegistryProviderClassName() and setServerRegistryProviderClassName() APIs.

I like to integrate Jasper Reports to ULC client and I know it using transfer files between server and client. But it would be better use output stream on the server side and transfer design or report to the viewer using input stream to the client side. I see possible solution to write custom coder for Serialisable type. It si possible? Thanks for advice Levcik Anton CIS Bratislava Slovakia
