How to get body-content value in my custom tag?

[somjet thana]

in jsp file

    
<%
request.setAttribute("name", "tom");
%>
<myTag:greeting>${name}</myTag:greeting>

How to get body-content(name) value in MyTag.doTag(), if MyTag extends SimpleTagSupport?

Thanks

If you want to simply output the body :

getJspBody().invoke(null);

If you want to do something with the body :

StringWriter sw = new StringWriter();
getJspBody().invoke(sw);

and how to get only string value of body-content in doTag()

    
String bodyContentValue = ???

[Christophe Verré]

Call the StringWriter#toString method.

Thanks.
with jsp code

    
<myTag:xxx>${name}</myTag:xxx>

Which is the correct use of EL(${name})?

1.use ${name} to input name param to doTag()
2.use ${name} to display name when we use getJspContext().setAttribute("name", "tom")
3.all correct

thanks

They all sound badly written. Where did you get them from ?

[somjet thana]

it is my doubt.
