A Note on the IPAWS-OPEN CAP 1.2 Interface for EAS Messages
IPAWS announced its CAP 1.2 Interface last Friday (30 September 2011).
The CAP 1.2 schema from OASIS imposes a pattern on date formats that forces the pattern to be exactly YYYY-MM-DDThh:mm:ss-hh:mm as specified in the CAP 1.2 schema. The last six could also be +hh:mm and represents the offset of the local time in the time string from GMT.
WSDL generated code from the IPAWS-OPEN WSDL may use a standard utility for converting a Java Calendar (or its equivalent in .Net) to a String for its XML writer that is in the form YYYY-MM-DDThh:mm:ss.nnn-hh:mm where the “.nnn” is in milliseconds. This will break the schema. In fact, it resulted in runtime errors in some code I generated from the CAP 1.2 WSDL for IPAWS-OPEN using Java axis2. My solution (credit to Prafash Kumar from Alerting Solutions who gave me his example) was to edit the stub code wherever there was a Calendar to string conversion to substring out the milliseconds from the conversion. There may be a better way, but my solution was successful. Here is a snippet I used in one of those conversion situations:
Original: xmlWriter.writeCharacters(org.apache.axis2.databinding.utils.ConverterUtil.convertToString(localEffective_type0));
Replacement: xmlWriter.writeCharacters(org.apache.axis2.databinding.utils.ConverterUtil.convertToString(localEffective_type0).replaceFirst(“.000”, “”));
I can get away with the “.000” string match because an incoming message to IPAWS-OPEN is also validated for a structure that contains no milliseconds, so the outgoing conversion will be a .000 if it is there at all.
