Thanks works fine... !!

Some of the features used here are deprecated, such as JRExporterParameter.OUTPUT_STREAM.
You should update your code.

I agree, some features are deprecated. Can yo update the code to version 6 ?

OUTPUT_STREAM Deprecated.
Replaced by SimpleWriterExporterOutput.SimpleWriterExporterOutput(java.io.OutputStream) and SimpleOutputStreamExporterOutput.SimpleOutputStreamExporterOutput(java.io.OutputStream).
