Re: Tags creating Tags
One way of accomplishing what you want to do, I think, is simply making calls to the appropriate Struts classes that are called when is parsed & compiled.

I think you'll still end up with a severe performance penalty. If you generate JSP dynamically, that JSP will have to be "pre-compiled" each time you re-generate it.

Re: Tags creating Tags
I apologize for the original cross-post. I was hoping there might be a Struts method to do what I wanted. Here is something I wrote to the other group, after a post from Felipe Leme. > I think you can accomplish what you're looking for using JSP 2.0 and tag > files. Yep. That's exactly what I'm looking for. Now Tomcat 5 just needs to be released, because I'm stuck with JSP 1.2 for now. *sniff* Thanks for the help everyone. I'm including a snippet from the JSP 2.0 PFD 3. Lukas JSP.8.1 Overview As of JSP version 2.0, the JSP Compiler is required to recognize tag files. A tag file is a source file that provides a way for a page author to abstract a segment of JSP code and make it reusable via a custom action. Tag files allow a JSP page author to create tag libraries using JSP syntax. This means that page authors no longer need to know Java or ask someone who knows Java to write a tag extension. Even for page authors or tag library developers who know Java, writing tag files is more convenient when developing tags that primarily output template text. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Tags creating Tags
Hi Lukas,
If I understand you correctly you need to look into the pushBody and
popBody methods on PageContext. Basically, in doStartTag(), call
pageContext.pushBody() then in doEndTag() you call
pageContext.popBody(), retrieve the BodyContent's value, muck about with
it to your heart's content, then output your transformed markup to the
current JspWriter.
Something like that anyway. This is off the top of my head so I may be
remembering the semantics slightly wrong, but I've definitely done this
before
class MyTag extends BodyTagSupport {
public int doStartTag() {
pageContext.pushBody();
return EVAL_BODY_INCLUDE;
}
public int doEndTag() {
pageContext.popBody();
String transformedMarkup =
doSomeTransformations(getBodyContent().getString());
pageContext.getOut().print(transformedMarkup);
return EVAL_PAGE;
}
}
Hope that helps,
Mark

Re: Tags creating Tags
Ruth, Craig, and lurkers, I think what I'm after boils down to a method like this: public String renderTag(PageContext pPageContext, Tag pTagToRender) throws JspException After creating the tag manually, you could pass it to this method, and have it rendered. The return value of a String should be the final output of the Tag. The method would check for BodyTag, IterationTag, etc support, and react to it. This way, the user could embed custom tags (Struts or otherwise) within their own custom tags. I'm surprised a method like this doesn't already exist. This wouldn't be recursive, nor would it recompile on each shot. You may be right in calling this a tad "hackish," but it would be useful, no? I can even think of another method that would be the incredi-hack: public String renderTag(PageContext pPageContext, Tag pTagToRender) throws JspException Where you pass in "" instead of the Tag object itself. Now that would be aggressive. For another approach, the JspFragment interface looks promising. However, I'm stuck with Tomcat 4.1 for now, so JSP 2.0 is out.

Lukas Bradley wrote: Ruth, Craig, and lurkers, I think what I'm after boils down to a method like this: public String renderTag(PageContext pPageContext, Tag pTagToRender) throws JspException A look at the JSP Specification will tell you that this would not work at all for a classic tag handler (i.e. implements Tag or implements BodyTag). After creating the tag manually, you could pass it to this method, and have it rendered. The return value of a String should be the final output of the Tag.

Now that would be aggressive. For another approach, the JspFragment interface looks promising. However, I'm stuck with Tomcat 4.1 for now, so JSP 2.0 is out. I think the approach you suggest is problematic, for many of the reasons that Action chaining is problematic. The most serious issue is that you're trying to use a JSP artifact (a custom tag implementation class) for something it was never designed to do (be a reusable "output generator" outside the context of the very strict and complex lifecycle for tag instances described in the JSP specfiication). "Hackish" does not begin to describe how much trouble this kind of anti-object-oriented approach will lead you to in the long run. The right answer would be to create your own tag class that does exactly what you want. If your tag wants to leverage functionality from existing tag classes (and you don't want to cut-n-paste), either make your class a subclass of the existing one (presuming the stuff you need is already abstracted into useful protected methods), or abstract the stuff you need into utility classes that can be shared between your tag and the standard ones, and then lobby to have the same factoring done in the standard classes. This is the foundational basis on which all Struts tag classes are organized, and has proven to support a pretty rich library of tag class implementations that (in many cases) reuse or specialize protected methods in their subclasses. In no case was a "generate a tag" type of hack considered, because it's not necessary. All that's necessary is applying sound design practices for factoring reusable code into reusable chunks. I won't try to claim that we've done a perfect job at the current factoring, but the existence of something like struts-el (which was basically built on top of the existing tags, without having to rip them apart) is pretty good evidence that we're on the right track. Trying to interfere with the tag instance lifecycle that the JSP page compiler assumes pretty much guarantees you'll end up with disaster.

RE: Tags creating Tags
Going from your example, I'm not sure why you even need to subclass a Struts
tag to get the output you described. You should be able to code something
like this on your JSP:
The tag handling flow would look like (similar to what you proposed
earlier):
myTag.doStartTag();
pageContext.getOut().println("");
*include output of body of custom tag here, which might be Struts tags
which are invoked.
myTag.doEndTag();
pageContext.getOut().println("");
Which would evaluate to
All this w/o changing or subclassing a Struts tag, the only Custom tag work
is myTag.
HTH,
Mike

RE: Tags creating Tags
There is a little more overhead than this.
You are now taking control of the struts tag lifespan. Currently, assuming
tag pooling, this is done by the container based on a hash of the parameter
values. If you are careful you can piggyback on that by synchronizing the
internal tag instantiation with your tag. You could instantiate the
internal tag on every reference, but that would be a step back in terms of
efficiency.
Then any jsp parameters you will be passing to the internal tag must be
passed prior to invoking the tag. Additionally, each of the methods of the
Tag or BodyTag interfaces must be implemented and call the internally
referenced tag based on the requirements of the tag. Most of the struts
tags don't have a 'real' body so this is not that important. If you were
considering wrapping the iterate tag, you would have an interesting problem.

RE: Tags creating Tags
Just to be clear, I'm not advocating that the custom tag internally
instantiate the Struts tag, but rather let the container instantiate them as
it encountered them in the JSP. So
CustomTag.doStartTag();
StrutsTag.doStartTag();
StrutsTag.doEndTag();
CustomTag.doEndTag();
The custom tag must enable it's body to be evaluated so the Struts tag is
invoked. but other than that.
