Iv�n,
Here's the custom tag to copy the JSP content:
CopyTag.java
--------------------
package utiltags;
import java.io.*;
import javax.servlet.jsp.JspException;
import javax.servlet.jsp.tagext.BodyTagSupport;
/**
* <p>Title: </p>
* <p>Description: </p>
* <p>Copyright: Copyright (c) 2002</p>
* <p>Company: </p>
* @author unascribed
* @version 1.0
*/
public class CopyTag extends BodyTagSupport {
public int doAfterBody() throws JspException {
try {
String content = bodyContent.getString();
pageContext.setAttribute(id,content);
bodyContent.writeOut(getPreviousOut());
}
catch(java.io.IOException e) {
throw new JspException(e.getMessage());
}
return SKIP_BODY;
}
}
CopyTagInfo.java
------------------------
package utiltags;
import javax.servlet.jsp.tagext.TagData;
import javax.servlet.jsp.tagext.TagExtraInfo;
import javax.servlet.jsp.tagext.VariableInfo;
/**
* <p>Title: CopyTagInfo.java</p>
* <p>Description: A TagInfo class for the CopyTag tag</p>
* <p>Copyright: Copyright (c) 2002</p>
* <p>Company: Single Track Software</p>
* @author Richard Yee
* @version 1.0
*/
public class CopyTagInfo extends TagExtraInfo {
public VariableInfo[] getVariableInfo(TagData data) {
return new VariableInfo[] {
new VariableInfo(data.getId(), // scripting var's name
"java.lang.String", // variable's type
true,
VariableInfo.AT_END)
};
}
}

utiltagtest.jsp
-------------------
<%@ taglib uri="utiltags" prefix="util" %>
<html>
<head>
<title>CopyTag Test</title>
</head>
<util:copyTag id='myVar'>
<body>
Hello World!
</body>
</util:copyTag>
<br>The value of myVar = '<%= myVar %>'
</html>
Note: the output of the jsp in the browser is:
Hello World!
The value of myVar = ' Hello World! '
This is not exactly what is expected. However, if you view the source, the
expected output is returned:
<html>
<head>
<title>CopyTag Test</title>
</head>
<body>
Hello World!
</body>
<br>The value of myVar = '
<body>
Hello World!
</body>
'
</html>
The difference is caused by the fact that html tags need to be escaped in
order to be visible to the user in the browser and not processed by the
browser.
If you use the mailer taglib which is available from www.jsptags.com, the
example jsp would then be:
<%@ taglib uri="utiltags" prefix="util" %>
<util:copyTag id='myVar'>
<html>
<head>
<title>CopyTag Test</title>
</head>
<body>
Hello World!
</body>
</html>
</util:copyTag>
<mt:mail server="your_server_name" to="destination@address"
from="your_sender_address" subject="your_subject">
<mt:message><%= myVar %></mt:message>
<mt:send/>
</mt:mail>
By using custom tags, you get a reusable piece of code that can be used
across multiple JSP's and avoid having scriptlets in your JSP.
