OutputClient.generatePDFOutput error inside Servlet

[mandtdev]

I am getting the following error when executing the OutputClient.generatePDFOutput method in Servlet environment. The same code works when called from the main method. Any ideas?? I am getting the error in JBOSS as well as Webshere

The following exception occurred:

java.lang.NullPointerException

I would review how you are reading the input data and creating the Document object required by the OutputClient. The null pointer exception appears to be pointing to a java.io.ByteArrayInputStream.

See the Document object at http://help.adobe.com/en_US/livecycle/9.0/programLC/javadoc/index.html

Document(byte[] data)

          Creates a new Document out of the content specified by the byte array.

Document(File file, boolean own)

          Creates a new Document out of the content stored in the file.

Document(InputStream is)

          Creates a new Document with the content provided by the java.io.InputStream object.

Document(URL url)

          Creates a new Document out of the content accessible via the URL.

If you could post the servlet source, I would be happy to take a look.
