Issue with creating Custom Tag Library in CQ5.5
Hi,
I am creating a custom tag library and want to use it in one of my components. I have created a bundle which includes tag hello class which is extending TagSupport class and i created tags.tld file under my resource folder
In my pom.xml, I have used resource tag to include my .tld file in the generated jar file.
Here is my java class and tld file
TAG CLASS:-
package com.cb;
import javax.servlet.jsp.*;
import javax.servlet.jsp.tagext.*;
/**
* Simple tag example to show how content is added to the
* output stream when a tag is encountered in a JSP page.
*/
public class Hello extends TagSupport {
private String name=null;
/**
* Getter/Setter for the attribute name
as defined in the tld file
* for this tag*/
public void setName(String value){
name = value;
}
public String getName(){
return(name);
}
/**
* doStartTag is called by the JSP container
when the tag is encountered */
public int doStartTag() {
try {
JspWriter out = pageContext.getOut();
out.println("<table border=\"1\">");
if (name != null)
out.println("<tr><td> Welcome <b>" + name +
"</b> </td></tr>");
else
out.println("<tr><td> Hello World </td></tr></table>");
} catch (Exception ex) {
throw new Error("All is not well in the world.");
}
// Must return SKIP_BODY because we are not
//supporting a body for this
// tag.
return SKIP_BODY;
}
/**
* doEndTag is called by the
JSP container when the tag is closed */
public int doEndTag(){
return EVAL_PAGE;
}
}
TLD File:-
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<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/web-jsptaglibrary_2_0.xsd" version="2.0">
<description>My tag library123</description>
<tlib-version>1.11</tlib-version>
<uri>http://cs.test.com/bundles/cq/1.11</uri>
<tag>
<name>hello</name>
<tagclass>com.cb.Hello</tagclass>
<bodycontent>empty</bodycontent>
<info>This is a simple hello tag</info>
<attribute>
<name>name</name>
<required>true</required>
<rtexprvalue>true</rtexprvalue>
</attribute>
</tag>
</taglib>
I also successfully installed the bundle in my felix console without having any error. Then i written custom tag in my jsp as below
JSP:-
<%@include file="/libs/foundation/global.jsp"%>
<%@ page import="com.cb.Hello"%>
<%@ taglib prefix="mytest" uri="http://cs.test.com/bundles/cq/1.11"%>
<mytest:hello name="sachin"></mytest:hello>
I am getting error as "org.apache.sling.api.scripting.ScriptEvaluationException: org.apache.sling.scripting.jsp.jasper.JasperException: /apps/test/components/content/test/test.jsp(4,0) Unable to load tag handler class "com.cb.Hello" for tag "mytest:hello".
The same code is working fine in my apache tomcat server without having any issue. I am getting the error when i incorporate it in CQ.
What am i doing here? Is there any config i need to do in OSGI console to make it available?
Please guide me to resolve.
Thanks
