[relaxng-user] date datatype, w3c, java, aargh

[George Cristian Bina]

Hi,

Here there are more details about the problem. The exception trace is:

java.lang.IllegalArgumentException: HOUR_OF_DAY
         at java.util.GregorianCalendar.computeTime(Unknown Source)
         at java.util.Calendar.updateTime(Unknown Source)
         at java.util.Calendar.getTimeInMillis(Unknown Source)

The line numbers may be a little different as I added a couple of debug 
lines in the code to figure out what happens.

Commenting the following lines in the DateTimeDatatype.createDate method:

// Using a time zone of "GMT+XX:YY" doesn't work with JDK 1.1, so we 
have to do it like this.
     cal.set(Calendar.ZONE_OFFSET, tzOffset);
     cal.set(Calendar.DST_OFFSET, 0);

makes the date datatype work with Java 1.5 but I do not know if this is 
the right fix for this problem.

Hope that helps,
George
