Unsupported media type when syncing with sync4j - Synthesis AG

rjroos · #1 2006-08-14, 14:17

Hi we're trying to let a blackberry talk to apache with the synthesis sysync module. Unfortunately it doesn't work out of the box. We get this conversation using ngrep. Any ideas?

This is because the XML data sent by the sync4j client lacks the <?xml version="1.0"?> prologue, so it is not recognized by the server as XML.

We are working to make the server more tolerant to such minor format problems in future versions. But in the strict sense, it's a sync4j problem.

I've just changed the Sync4J application, and now it does include <?xml version="1.0"?>, but we still get the same response:
