Hi, I just upgraded from ActiveMQ CMS 3.1.3 to 3.2.1, and I'm having some trouble reading empty strings out of MapMessage fields after sending them through the broker. When I try to do so, MapMessage::getString() throws the exception "Unsupported Type Conversion".
To explain, here's what I do: - Open a connection with my ActiveMQ broker - Create a MapMessage. Set two string fields, one empty, one non-empty: - request->setString("STR_FIELD_1", ""); - request->setString("STR_FIELD_2", "asdf"); - Send the message to a queue - Read the message from the queue - Read the two string fields from the response: - response->getString("STR_FIELD_1", ""); - response->getString("STR_FIELD_2", "asdf"); Reading the non-empty string field works fine. Reading the empty one, however, results in the exception "Unsupported Type Conversion". Any idea why this is happening? I did not experience this with CMS 3.1.3. For reference, I'm using: - CMS 3.2.1 on Windows XP - ActiveMQ 5.3.0 and Java 1.6.0 on Red Hat Enterprise Linux Server release 5.3 (Tikanga) - Sending messages to a queue, using persistent messaging (via KahaDB) Here is a small C++ program I'm using to reproduce the problem: http://old.nabble.com/file/p29249684/send_empty_string.cpp send_empty_string.cpp Thank you very much for your help - Evan Kuhn -- View this message in context: http://old.nabble.com/CMS-3.2.1---Trouble-reading-empty-strings-from-MapMessage-fields-tp29249684p29249684.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
