Subject RE: porting to tomcat 5
Date Wed, 15 Sep 2004 04:50:05 GMT
Please note, these jsps and tag library were written on the servlet/jsp
2.2/1.1 spec, so I don't think this stuff was available at that time (I
maybe be wrong though).

Anyway, about the storevalue tag: it takes the value of the column in
the sql resultset identified by "transactId" and writes it to the output
stream. But this doesn't really matter, because if you look at the JSP
then see what tomcat generates, there's obviously an error in the way
Tomcat is handling this case. 

In fact I changed the storeValue tag to our storeRowCount, which creates
a variable like storeValue except it stores the row count for the
results from a particular sql transaction. However I still had the same
result... Tomcat doesn't define the variable in the second if block.

Thanks for the help.

although i didnt understand what the <trans:storeValue tag, for pure
jstl i would have in my code something like this

<c:choose>
<c:when test="${param.mode == 'SearchContacts'}">
   <c:set var="tmpEmail" value="accountSearchPersonal" />
</c:when>
<c:otherwise>
</c:otherwise>
   <c:set var="tmpEmail" value="accountSelectPersonal" />
</c:choose>
