Java_JSTL_extend function tags

1.create the function class

package cn.com.benyoyo.manage.core.common.tools;
public class ElExFuncs {
public static int lastIndexOf(String text, String searchString) {
if (text == null) text = "";
if (searchString == null) searchString = "";
return text.lastIndexOf(searchString);
}
}

2. create tld file

<?xml version="1.0" encoding="UTF-8" ?>
<taglib xmlns="http://java.sun.com/xml/ns/j2ee"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-jsptaglibrary_2_0.xsd"
  version="2.0">
  <description>A extend JSTL 1.1 functions library for cmis</description>
  <display-name>JSTL extend functions</display-name>
  <tlib-version>1.1</tlib-version>
  <short-name>fn-ex</short-name>
  <function>
    <description>Returns the index withing a string of the last occurrence of a specified substring.</description>
    <name>lastIndexOf</name>
    <function-class>cn.com.benyoyo.manage.core.common.tools.ElExFuncs</function-class>
    <function-signature>int lastIndexOf(java.lang.String, java.lang.String)</function-signature>
    <example>
      ${fn:lastIndexOf(name, "-")}
    </example>
  </function>
</taglib>

3.import taglib in jsp

<%@ taglib prefix="fnex" uri="/WEB-INF/config/tld/fn-ex.tld"%>
