Pass scrape taglib to a method (string)
Hello,
How can I pass the value of the scrape taglib to a method? It seems to
me that it should be something like:
<% // snag text and stick it into 'teststring'
String teststring = pageContext.getAttribute( "<scrp:result
scrape="pj3"/>" );
%>
But it doesn't like the syntax. I'm new to this...
Thanks for your help.
Karen

Posted by "K.C. Baltz" <kc...@lollimail.com>.
<% %> - Denotes a "scriptlet", java code that is directly inserted
into a generated Servlet
The tags you are trying to use are called "custom tags", and they can't
be used inside scriptlets any more than you could do:
<%
<html>
%>
Whatever appears within a scriptlet must be Java code.
If you can, try to avoid mixing custom tags and scriptlets. Although
it's possible to do this, it can be very confusing for new users of JSP
and tags.

Yep, that'll create one :-) -- don't enclose these tags:
<c:set var="teststring"><scrp:result scrape="pj3"/></c:set>
in a scriptlet section ( the <% ... %> )

x:transform and body content
Posted by "Mark R. Diggory" <md...@latte.harvard.edu>.
I'm trying to dynamically set the parameters on an x:transform based on
the params in the http request like below:
<c:import var="default" url="/Study/DataSubsettingView.xsl"/>
<x:transform xml="${dom}" xslt="${xslt}">
<c:forEach var="entry" items="${param}">
<c:if test="${entry.key ne 'var'}">
<x:param name="${entry.key}" value="${entry.value}"/>
</c:if>
</c:forEach>
</x:transform>
but I keep getting
27: Encountered illegal body of tag "x:transform" tag, given its attributes.
Is there any way to do this dynamically?

Karen.
I guess you didn't get the mail from Hassan Schroeder.
<c:set...> is a custom tag and must not be included inside scriptlet
tags (<% %>). You use it just like any other HTML tag.

Hello all,
I understand this but the problem is that I need to use the output
within a scriplet. Is that possible?
<c:set var="teststring"><scrp:result scrape="pj4"/></c:set>
<c:out value="${teststring}" />
Will output the string but I can't use it within a scriplet
If I call the variable teststring in a scriplet, like
<%= teststring %>
I get: No entity named "teststring" was found in this environment
I tried changing the scope but that didn't help. I need to pass this
string to a method that someone else wrote....
I'm just getting started with these taglibs and appreciate any help that
anyone can give.
Thank you,
Karen
