XSl using XALAN - problem: Hi, I am using xalan parser to convert xml to HTML using xsl. The code is as follows XML file: <?xml version="1.0"?> <?xml-stylesheet type="text/xsl" href="results.xsl"?> <entries gameID="DWO"> <entry> <player>John</player> <guess>3</guess> <guess>9</guess> <guess>222</guess> </entry> <entry> <player>Mary</player> <guess>88</guess> <guess>76</guess> <guess>5</guess> </entry> </entries> XSL file: <?xml version="1.0"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:lxslt="http://xml.apache.org/xslt" xmlns:result="http://www.example.com/results" extension-element-prefixes="result" version="1.0"> <lxslt:component prefix="result" elements="rules" functions="getResult"> <lxslt:script lang="javascript"> function getResult (thisGuess) { var thisResult = parseInt(Math.random()*100); if (thisResult == parseInt(thisGuess)) { return "Correct!"; } else { return "Wrong! The actual answer was "+thisResult+ ", not "+thisGuess+"."; } } </lxslt:script> </lxslt:component> <xsl:template match="/"> <xsl:apply-templates/> </xsl:template> <xsl:template match="entry"> Guesser: <xsl:value-of select="player"/> <xsl:apply-templates select="guess"/> </xsl:template> <xsl:template match="guess"> Guess: <xsl:value-of select="."/> Actual: <xsl:value-of select="result:getResult(string(.))"/> </xsl:template> </xsl:stylesheet> I have put the following files in the lib directory of Ant build. 1)xml-apis.jar 2)xercesImpl.jar 3)xalan.jar 4)styler.jar 5)bsf.jar 6)js.jar and i have included the lib directory in the classpath. if i run a code without a javascript function it works fine, but with the javascript i get the error D:\deepak\buildProcess_2\logging>java org.apache.xalan.xslt.Process -IN D:\deepak\buildProcess_2\logging\cart.xml -XSL D:\deepak\buildProcess_2\logging\res ults.xsl -OUT D:\deepak\buildProcess_2\logging\xalan.html java.lang.ClassNotFoundException: com/ibm/bsf/BSFManager ... ... ... Caused by: javax.xml.transform.TransformerException: Could not initialize BSF Manager at org.apache.xalan.extensions.ExtensionHandlerGeneral.<init>(Unknown Source) ... ... ... file:/D:/deepak/buildProcess_2/logging/results.xsl; Line #33; Column #-1; XSLT Error (javax.xml.transform.TransformerException): java.lang.NullPointerExcep tion So something must be wrong with the bsf.jar file. where should i put the file so that its being recognised? the js.jar file is also at the right place. where am I wromg? bye, with regards, Deepak. __________________________________ Do you Yahoo!?
