The body of the tag that is a TAG FILE can not have scriptlets.

The body of a simple tag that extends SimpleTagSupport can not have scriptlets, because its body is a JspFragment that does not allow scriptlets.
So does this mean this is illegal for a simple tag tld:
<body-content>JSP</body-content>
?


What about classic Tag handler that extends TagSupport and BodyTagSupport? Can we put scriptlets in the tag body?

JSP is an illegal value for the <body-content> tag.

Yes you can specify body content as "JSP" which includes anything you can write in a jsp file.

Thanks for all the answers. So am I right to say that only classic tag handlers can have scriplets in the tag body, while tag files and simple tags cannot?
