hello , sorry to repost this question..
i did not get a response for my question. can some one please answer me?? hello i have a question regarding using the extension library function ussage. i have seen articles that use the toUpperCase of String method in the following way. for xml <colors> <color>red</color> <color>blue</color> <color>green and pink</color> </colors> using the java's to upper case, the xsl would be <?xml version="1.0"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xalan = "http://xml.apache.org/xalan" exclude-result-prefixes="xalan" xmlns:java = "java"> <xsl:template match="/"> <xsl:for-each select="/colors/color"> <xsl:variable name="color" select="java:lang.String.new(.)"/> from java: <xsl:value-of select="java:toUpperCase($color)"/> </xsl:for-each> </xsl:template> </xsl:stylesheet> where we instantiate the String object by saying java:lang.String.new() and then call the toUpperCase Method on that string. thaz fine. I have then formed my own utility class that returns the string in the uppercase( just for test purpose ). This Class is StrUtils which has a method called upperCase()that takes the String to be converted to the uppercase and returns String in uppercase. ( I am doing this purely for test purpose) and i am calling this method in the following way in my XSL <?xml version="1.0"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xalan = "http://xml.apache.org/xalan" exclude-result-prefixes="xalan" xmlns:str-utils = "com.xyz.StrUtils" extension-element-prefixes ="str-utils" > <xsl:template match="/"> <xsl:for-each select="/colors/color"> <xsl:variable name="color" select="."/> <xsl:value-of select="str-utils:upperCase($color)"/> </xsl:for-each> </xsl:template> </xsl:stylesheet> This works fine too. My question is that in my Example, where is the instantiation being done?? I have not done anything like com.xyz.StrUtils.new()... so how is it working?? what is the theory behind the object instantiation when it comes to extension libraries?? The StrUtils Class is as follows public class StrUtils { /** * Constructor for the StringUtils object */ public StringUtils() { } public String upperCase(String str) { return "str.toUpperCase() "+str.toUpperCase(); } } i would be thankful if someone can please tell me about this. _________________________________________________________ Click below to visit monsterindia.com and review jobs in India or Abroad http://monsterindia.rediff.com/jobs XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
