For a variable 'foo' you can do things like
${foo.substring(12)}
or
<j:if test="${foo.endsWith('sometext')}">
...
There's a current Jexl limitation which should hopefully go soon that dots
inside variable names confuse it. So if your variable is called "a.b.c" then
something like this would work around Jexl's current limitation...
<j:if test="${context.getVariable('a.b.c').endsWith('sometext')}">
...
Or you could just reassign your variable to one without dots...
<j:set var="foo" value="${a.b.c}"/>
<j:if test="${foo.endsWith('sometext')}">
...

XPath support is available in the XML tag library. So you could do
<x:if test="substring-after($a.b.c, 'sometext')">
...
or whatever other XPath expression you want to use...

You can concatenate via expressions
<j:set var="foo" value="something${expr}something${expr}something"/>
Or you can use other nested tags and expressions to set the value.
<j:set var="foo">
some text
<j:if test="...">...</j:if>
etc
${whatever}
something else
</j:set>
