Problem in compiling XSL to translet - fails at Java method

Hi, 
 
I am using version 2.6.0 of Xalan/XSLTC for carrying
out XSL 
transformations using translets. Problem arises when I
try to compile my xsl file 
to a translet. The following part in the XSL fails
compilation - 
 
<xsl:otherwise>
        <xsl:variable name="number" 
select="EMPDB_2472Group/EMPDB_2472[position()=$feepos]
* 0.9"/>
        <xsl:variable name="roundnumber" select="5"/>
        <xsl:variable name="flag" select="0"/>
        <xsl:variable name="output" 
select="util:RND1($number,$roundnumber,$flag)"/>
        <xsl:if test="$output != ''">
         <xsl:value-of 
select="format-number($output,'$##,###,##0.00')"/>
        </xsl:if>
       </xsl:otherwise>
 
with the error like :
 
ERROR:  'Cannot convert argument/return type in call
to method 
'X.Y.Z.XSLUtils.RND1(real, int, real)''
FATAL ERROR:  'Could not compile stylesheet'
Exception:
javax.xml.transform.TransformerConfigurationException:

not compile stylesheet
javax.xml.transform.TransformerConfigurationException:

compile stylesheet
        at 
org.apache.xalan.xsltc.trax.TransformerFactoryImpl.newTemplates(TransformerFactoryImpl.ja
va:753)
        at XSLCompiler.generateXSLClassFile(Unknown
Source)
        at XSLCompiler.main(Unknown Source)
 
The java method which I am trying to invoke is - 
 
    public static String RND1(String number, String
roundnumber, String 
flag) {
        double temp = 0;
        double num = Double.parseDouble(number);
        double roundnum =
Double.parseDouble(roundnumber);
        temp = num % roundnum;
        if (temp == 0)
            num = num;
        else {
            if (flag.equals("1")) {
                temp = roundnum - temp;
                num = num + temp;
            } else if (flag.equals("0")) {
                num = num - temp;
            } else if (flag.equals("2")) {
                double temp1 = 0.0;
                temp1 = (num / roundnum) % 1;
                if (temp1 > 0.4) {
                    temp = roundnum - temp;
                    num = num + temp;
                } else {
                    num = num - temp;
                }
            }
        }
        log("******** XSLUtils Log  Rounding " +
number + "  " + num);
        return num + "";
    }

I have made sure that correct files are in the
classpath. When I do the 
following chage in the xsl above, the compilation goes
through - 
 
        <xsl:variable name="roundnumber" select="a"/>
        <xsl:variable name="flag" select="b"/>
 
It seems there is some problem with passing the
integer values to the 
java method. But other such java methods are working
fine in the same 
xsl. 
 
Am I missing something obvious ?
Please advice. 
 
Thanks.
