Johannes,
I tried using

<xsl:value-of select="java:java.util.Calendar.get($tmp, 1)">

, but I got the following error on the line where I made the call.
I used the -TS option in Xalan to get results in the console

Line #37, Column #41: value-of, select='' '': Line #39, Column #76: variable, select='java:java.util.Calendar.getInstance()': java.util.GregorianCalendar[time=1018888 758479,areFieldsSet=true,areAllFieldsSet=true,lenient=true,zone=java.util.SimpleTimeZone[id=America/New_York,offset=-180 00000,dstSavings=3600000,useDaylight=true,startYear=0,startMode=3,startMonth=3,startDay=1,startDayOfWeek=1,startTime=720 0000,startTimeMode=0,endMode=2,endMonth=9,endDay=-1,endDayOfWeek=1,endTime=7200000,endTimeMode=0],firstDayOfWeek=1,minim alDaysInFirstWeek=1,ERA=1,YEAR=2002,MONTH=3,WEEK_OF_YEAR=16,WEEK_OF_MONTH=3,DAY_OF_MONTH=15,DAY_OF_YEAR=105,DAY_OF_WEEK= 2,DAY_OF_WEEK_IN_MONTH=3,AM_PM=1,HOUR=0,HOUR_OF_DAY=12,MINUTE=39,SECOND=18,MILLISECOND=479,ZONE_OFFSET=-18000000,DST_OFF SET=3600000] file:///C:/xalan-j_2_0_D07/intact.xsl; Line 40; Column 63 Parser error: TRaX Transform Throwable

XSLT Error (javax.xml.transform.TransformerException): TRaX Transform Throwable

Any ideas?

<xsl:value-of select="java:java.util.Calendar.get(YEAR)"/>

will invoke the static (non-existent) method "get" in class
java.util.Calendar and pass as parameter the result of evaluating the
child-axis-expression YEAR.

Try instead:

<xsl:value-of select="java:java.util.Calendar.get($tmp, 1)">

This will invoke the non-static method "get" on the Calendar object stored
in variable $tmp and pass number 1 as parameter, which is the value of
constant Calendar.YEAR.

regards,
Johannes

Hello ladies/gents, I am trying to use extensions in XSLT to get the
current date/time for textual output, but I don't know how to retrieve
specific data from the object returned.

Below is a sample of the xsl file that makes the extension call:

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
             version="1.0"
             xmlns:java="http://xml.apache.org/xslt/java">

..
..
<!-- I am making this call inside the template: -->
<xsl:variable name="tmp" select="java:java.util.Calendar.new()"/>
<xsl:value-of select="$tmp" />
..
</xsl:stylesheet>

The problem with this is that, when I instantiate the Calendar object it
returns a GregorianCalendar object with a great deal of information that I
don't want. So when I write it to output, the entire object is returned.
All I need on the text output is YYYYMMDDHHMMSS. These details are stored
in the attributes of the Class.
YEAR MONTH DAY_OF_MONTH HOUR_OF_DAY MINUTE SECOND

I tried using
"<xsl:value-of select="java:java.util.Calendar.get(YEAR)" />" etc., but I
got error messages when the processor tried to process these lines.

Can someone give me some pointers on this?

Thanks
Garvin
