Solved: Call Java method from Javascript (in XSL)

In my XSL, I am calling a Javascript method. From this Javascript method, I need to call a Java method. Please let me know how to do this.
If I simply write this in javascript
java_func_1:fileViewer('0900054d8000cf8e');
it does not work

xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:java_func="com.common.utils.SUtils"
xmlns:java_func_1="com.components.detailedView.FkDetailedView"
extension-element-prefixes="java_func java_func_1" version="2.0">
....
<xsl:template match="/">
     <html>
         <head>
            <script language="javascript">
				<![CDATA[
				function displayFile() {
				    alert("works");
                                    java_func_1:fileViewer('0900054d8000cf8e');
				}
				]]>
		    </script>
         </head> 
         <body>
        <xsl:apply-templates />
         </body>
     </html>
    </xsl:template>
...
...
             <tr  class="row1">
                 <td>
                     <xsl:for-each select="fb_holder/attached_files/file_details">
                        <a href="#" onclick="javascript:displayFile();"><xsl:value-of select="file_name"/></a><br/>
                    </xsl:for-each>
                </td>
            </tr>
