Re: [Jelly] Concatenate variable values or strings

[Paul Libbrecht]

You can certainly make more elegant things but I fear it would require extensions of Jelly. One interesting thing would be to be able to convert a list of XPath result-nodes into a string with appropriate separators (presumably of any iterator convertible)... someone should volunteer for such a tag in util.

I want to get a java classpath into a long string sepearted by ;.
The path consists of all maven dependencies. Is there a easier/better way to
concatenate the string than this:

<j:set var="path" value="default.jar;"/>
<j:forEach var="dep" items="${pom.dependencies}">
<j:set var="path" trim="true">
${path}${dep.artifactId};
</j:set>
</j:forEach>
<echo>${path}</echo>

I just want to write good jelly code. :-)

Bye
Toby
