coupla easy (I hope) beginner questions
Hail gurus!
I've got a jsp page taking a session-context Collection
of forms and displaying it, and I'm trying to add
a delete and an edit link or form on a per-row basis.
Seems like a pretty obvious thing, right? Based on
a tip from this list, I tried the following, after
considerable screwing around with other variants.
The jsp code looks (right now, formatting stripped out) like:
### SNIPPET
<logic:present scope="session" name="allContacts">
<table border="1" cellspacing="2" cellpadding="2">
<logic:iterate id="collectionElement" name="allContacts">
<tr>
<td>
<bean.define id="eltId"><bean:write name="collectionElement"
property="id"/></bean.define>
<html:link
page="deleteContact.do?id=${eltId}">Delete Contact</html:link>
</td>
<td><bean:write name="collectionElement" property="salutation"/></td>
<td><bean:write name="collectionElement" property="firstName"/></td>
...
### !SNIPPET
and the generated HTML looks (right now, formatting stripped out) like:
### SNIPPET
<table border="1" cellspacing="2" cellpadding="2">
<tr>
<td>
<bean.define id="eltId">e682d6b47f00000101616dd681dc2378</bean.define>
<a href="deleteContact.do?id=${eltId}">Delete Contact</a>
</td>
<td>mr</td>
<td>tim</td>
...
### !SNIPPET
The first beginner question (I've been working in C and SQL and
POJO Java for many years, but I'm very green at all this Web/app server
stuff): How do I get the eltId from the bean:define into the param
for deleteContact.do?
Obviously, with JSTL's c:set, right? Which brings us to the second
beginner question: Has anybody been able to use JSTL in an Eclipse 3.0/
JBoss 3.2.3/JBoss IDE environment? I locate the jars and TLD files
correctly and include the TLDs in web.xml (via taglibs.xml) correctly,
but on deployment of the EAR I get a error along the lines of:
Document root element "taglib", must match DOCTYPE root "null"
about the c.tld file itself (and similarly for all the other JSTL
tag files). I read something on the web about hacking my web.xml
file to be 2.4 instead of 2.3 (and some other stuff you have to
do to the web.xml DOCTYPE declaration). Since web.xml is completely
generated in this environment, that's not a real fix, but I tried it
anyway, and the results were the same. I've tried this will all of
c.tld, c-1_0.tld and c-1_0-rt.tld. Anyone? Anyone? Bueller?
Many thanks to anyone who can smarten up this chump.

Hi,
Is "bean.define" correct?
Anyway you have to use <bean:define ...> and </bean:define>.
Furthermore, in order to use the Struts tag without the el-extension
(you can find them in the "contrib" directory inside the Struts 1.1
binary release) you have to use a 2.4 servlet (and jsp 2.0)
Web-container compliant (for example Tomcat 5.0.x) and JSTL1.1.

I'm no guru, but....
You can put the appropriate HTML stuff in, but
the basics are as follows:
<logic:iterate id="collectionElement" name="allContacts"> <html:link
action="/deleteContact"
paramId="id"
paramName="collectionElement"
paramProperty="eltId"/>
</logic:iterate>
Sorry, can't help you with your second question :(
