You can invoke any method on any object using normal Java syntax thanks to
Jexl. So you could do
<j:set var="a">Martin van den Bemt</j:set>
<j:set var="b">Martin</j:set>
<j:set var="c" value="${a.substring(b.length())}"/>
If you wish.
It might be interesting to consider binding, say, the StringUtils in
commons-lang into a Jelly library.
http://jakarta.apache.org/commons/lang/api/org/apache/commons/lang/StringUti
ls.html
One thing we've not yet tried experimenting with is to turn static helper
methods into a Jelly library, or to add custom functions to Jexl.
