Now that WebObjects 5.4 has "full support" of XML plists, I was
hoping that I could rely on NSPropertyListSerialization to exchange
XML plists between Cocoa and WebObjects applications. However, I have
found that the date representations used by Cocoa and WebObjects 5.4
to be incompatible.
In Cocoa, NSPropertyListSerialization encodes/decodes <date> using
this format:
yyyy-mm-ddTHH:MM:SSZ
For example:
NSData *xmlData = [NSPropertyListSerialization dataFromPropertyList:now
format:NSPropertyListXMLFormat_v1_0
errorDescription:&error];
produces:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://
www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<date>2008-01-22T23:17:14Z</date>
</plist>
However, in WebObjects 5.4, NSPropertyListSerialization encodes/
decodes <date> using this format:
yyyy-mm-dd HH:MM:SS.NNN GMT
For example:
String xmlString =
NSPropertyListSerialization.xmlStringFromPropertyList(new NSTimestamp
());
produces:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://
www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<date>2008-01-22 21:39:22.975 GMT</date>
</plist>
You might expect both Cocoa and WebObjects
NSPropertyListSerialization to recognize both formats, but they don't.
Therefore:
Cocoa's NSPropertyListSerialization cannot decode a date encoded in
an XML plist generated by WebObjects.
WebObjects' NSPropertyListSerialization cannot decode a date encoded
in an XML plist generated by Cocoa.
I understand that Cocoa uses NSDate and WebObjects uses NSTimestamp
to represent dates. But I would have thought they could have used a
common XML representation.
I have been working around the problem that <date> isn't supported at
all in WO 5.3. However, I was really hoping that WO 5.4 would allow
me to ditch the workarounds.
Any thoughts?
