Hello,
I am willing to create custom tags that have the expression evaluation of the JSTL
1.0.5.
I am using tomcat 4, JDK1.4, thus cannot switch to JSTL1.1 .
I found the org.apache.taglibs.standard.lang.support.ExpressionEvaluatorManager class
that seems to be pretty cool. So I made my tags use it, but without success.
In my case I have a tag like:
<c:forEach begin="${0}" end="${labelssize - 1}" var="iteratecount">
<mytags:selectitem table="${labels}" index="${iteratecount}" item="item">
</c:forEach>
where the bean "labels" contains a java.util.List .
selectitem is supposed to return in the bean named "item" the Object at index
${iteratecount} of labels.
So in the java code I put:
Object object = ExpressionUtil.evalNotNull("SelectItem", "table", table, List.class,
this, pageContext);
*table being the String set by parameter table of cours*
which, unfortunatly returns an error:
"An error occurred while evaluating custom action attribute "table" with value
"labels": Attempt to convert String "labels" to type "java.util.List", but there is no
PropertyEditor for that type (null) "
Isn't ExpressionUtil.evalNotNull not supposed to returned the Object found behind the
bean of resulting parsed String?
Maybe the org.apache.taglibs.standard.lang.support.ExpressionEvaluatorManager is not
supposed to be used for custom tags?
Is there a howto about this?
I have also another question, but this might not be the best mailing list to ask this:
I am using taglibs with tomcat and struts. But I have a lot of logs that never show up
anywhere :p (such as the taglib is not found, throws an error, or struts does not find
the action, etc...).
Could you suggest me a link or two to help me figure out how to configure the stuff
correctly?
Sorry if these questions have been asked many times already, but I could not find a
suitable google answer...
