I see you are trying to do this with Java extensions. I don't know if and how this can work, but I can suggest a purely (almost) XSLT 1.0 solution. The following stylesheet:

XSLT 1.0

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:date="http://exslt.org/dates-and-times"
extension-element-prefixes="date">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>

<xsl:variable name="today" select="date:date()" />

<xsl:template match="/">
    <output>
        <start>
            <xsl:value-of select="concat(substring($today, 6, 2), '-', substring($today, 9, 2), '-', substring($today, 1, 4))" />
        </start>
        <end>
            <xsl:call-template name="add-days-to-today">
                <xsl:with-param name="days-to-add" select="90" />
            </xsl:call-template>
        </end>
    </output>
</xsl:template> 

<xsl:template name="add-days-to-today">
    <xsl:param name="days-to-add"/>
    <xsl:param name="year" select="substring($today, 1, 4)"/>
    <xsl:param name="month" select="substring($today, 6, 2)"/>
    <xsl:param name="day" select="substring($today, 9, 2)"/>
    <xsl:param name="a" select="floor((14 - $month) div 12)"/>
    <xsl:param name="y" select="$year + 4800 - $a"/>
    <xsl:param name="m" select="$month + 12*$a - 3"/>
    <xsl:param name="JDN" select="$day + floor((153*$m + 2) div 5) + 365*$y + floor($y div 4) - floor($y div 100) + floor($y div 400) - 32045 + $days-to-add" />
    <xsl:param name="f" select="$JDN + 1401 + floor((floor((4 * $JDN + 274277) div 146097) * 3) div 4) - 38"/>
    <xsl:param name="e" select="4*$f + 3"/>
    <xsl:param name="g" select="floor(($e mod 1461) div 4)"/>
    <xsl:param name="h" select="5*$g + 2"/>
    <xsl:param name="D" select="floor(($h mod 153) div 5 ) + 1"/>
    <xsl:param name="M" select="(floor($h div 153) + 2) mod 12 + 1"/>
    <xsl:param name="Y" select="floor($e div 1461) - 4716 + floor((14 - $M) div 12)"/>
    <xsl:param name="MM" select="format-number($M, '00')"/>
    <xsl:param name="DD" select="format-number($D, '00')"/>
    <xsl:value-of select="concat($MM, '-', $DD, '-', $Y)" />
</xsl:template>     

</xsl:stylesheet>

when applied to any XML input (on Dec 11, 2014), returns:

<?xml version="1.0" encoding="UTF-8"?>
<output>
   <start>12-11-2014</start>
   <end>03-11-2015</end>
</output>

<xsl:element name="App_Data">

                    <xsl:attribute name="Name">Licensing_Window_Start</xsl:attribute>

                                        <Licensing_Window_End>

                                            </xsl:call-template>
                                        </Licensing_Window_End>
                                    </output>

                    </xsl:attribute>
                </xsl:element>

Positioned the Variable Today and Template of Add-Day-To_Today at the top of the style sheet. Works Great. Thanks Again.
