I have a TLD file under WEB-INF folder

And I have a jsp pages with content

When I tried this code the first tag content with text works on the other hand the second tag gives exception like below... I would like to use any JSP in my tag body!!

org.apache.jasper.JasperException: /jsppages/tagsuse.jsp(27,1) The TLD for the class com.tt.taghandlers.SimpleExWithBody specifies an invalid body-content (JSP) for a SimpleTag.
org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:40)

Hi,

as the error message says, you cannot include scripting code in the body of a SimpleTag. This is the reason why the following line in the TLD is not valid:

<body-content>JSP</body-content>

If you really need to use scripting code, then you should go for the Classic Tag (by implementing the javax.servlet.jsp.tagext.Tag interface).

SCJP1.4: 96% SCWCD5: 91%

You can't use scripting inside the tag's body for SimpleTag implementations, basically this is because the body of a Simple Tag Handler is represented by JspFragment which does not support scriplets, therefore the <body-content> may not be "JSP"

Here are a few resources to help you understand why:
