Problem in XSL function call

[padhu_cbe]

Hi,

Requirements:
Need to find the DAY-NAME from the date.

I used the XSL function in my XSL file.

<xsl:function name="functx:day-of-week-name-en" as="xs:string"
xmlns:functx="http://www.functx.com">
<xsl:param name="date" as="xs:anyAtomicType?" />
<xsl:sequence
select="('Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday')[functx:day-of-week($date) + 1]" />
</xsl:function>

and I use this piece of code to call the function:

Declare a variable 'sDate'

<xsl:variable name="sDate">
<xsl:value-of select="input1/date1"/>
</xsl:variable>

And pass the variable 'sDate' as parameter to the function:

<xsl:element>
<xsl:value-of select="functx:day-of-week-name-en($sDate)" />
</xsl:element>

This is the Java code for Transformation:

public class XMLXSLT {
	public static void main(String[] args) throws TransformerException, 
    TransformerConfigurationException, 
    FileNotFoundException, IOException{
		TransformerFactory tFactory = 
	        TransformerFactory.newInstance();
	        			Transformer transformer = tFactory.newTransformer(new StreamSource("<PathName>/DateOfWeek.xsl"));
		 	transformer.transform(new StreamSource("<PathName>/date.xml"), new StreamResult(new FileOutputStream("<PathName>/dateout.xml"))); 
			System.out.println("** The output is written in **");
	}
}

The following error is thrown while executing the above code:

Compiler warnings:
  file:///Users/padmanaban/Padmanaban/EclipseWorkspace/XMLXSLTTest/DateOfWeek.xsl: line 41: You cannot call an element ''
ERROR:  'The first argument to the non-static Java function 'dayOfWeekNameEn' is not a valid object reference.'
FATAL ERROR:  'Could not compile stylesheet'

	at com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl.newTransformer(TransformerFactoryImpl.java:624)
	at XMLXSLT.main(XMLXSLT.java:25)

Can anyone help on resolve this?

Thanks,
