[HAPI-devel] Error while sending Base64 String inside OBX 5 field of ORU_R01 message

[Uddipan M. <udd...@tc...>]

 Hi all,

I am facing a problem while sending a base64 string inside HL7 message in the OBX segment field 5 of the ORU_R01 message.
Actually I have encoded one png image in base64 string and the size of base64 string is around 37kB.

But while receiving the message on server side(inside servlet) I am getting an error.(I am trying to receive the message in processMessage method with signature public Message processMessage(Message theMessage, Map<String, Object> theMetadata) throws ReceivingApplicationException, HL7Exception)

Jul 19, 2013 2:35:06 PM org.apache.catalina.core.StandardWrapperValve invoke
SEVERE: Servlet.service() for servlet [com.tcs.hl7server.MyServer] in context with path [/MyHL7Server] threw exception

But if I try to capture the incoming HL7 message in doPost method of the servlet,the Message can be read using BufferedReader.


Can anyone please point out why the error is coming at line no 370 in AbstractHl7OverHttpDecoder.java ?Is there any size limit of HL7 message implemented using HAPi?
