Hi. Sorry if this is a newbie question, but I can't find it on the
mailing lists or anywhere.
I'm using Jelly within Maven, and I'm trying to access elements in two
parallel arrays. My script looks something like this:
<u:tokenize var="names" delim=",">${foo.names}</u:tokenize>
<u:tokenize var="classes" delim=",">${foo.classes}</u:tokenize>
<j:forEach items="${names}" var="name", indexVar="i">
<ant:echo>name = ${name}, class = ${classes}[${i}]</ant:echo>
</j:forEach>
Obviously, the second part of my ant:echo line doesn't work, but my
questions are:
1) How do you access an item in an array in Jelly - I can't seem to
find anything that says what the syntax is
As in java... the following works:
<j:jelly xmlns:j="jelly:core">
<j:set var="x" value="xx"/>
<j:set var="x" value="${x.toCharArray()}"/>
${x[0]}
</j:jelly>
(i.e. its output is x)
2) Is this the best way to handle parallel arrays in Jelly?
Now, be careful util:tokenize doesn't produce arrays! It produces a
List... so
${classes[i]} might not work but ${classes.get(i)} does work.
I think the way you've done with the index is the way to process
parallel arrays. You could also use an iterator!

PS: so many folks forget that jelly is not in an opaque bizarre language
but just in java.... having problems with object x, try
${x.getClass()}... then use the appropriate methods!
