EL: concat strings

[Timo Nentwig]

Hi!

How can I concat strings with EL? ${str1 + str2} throws an exception -
it tries to cast String to Double so the + operator obviously does not
apply to Strings as it does in Java.

${st1}${str2}

Oops...

Anyway, there are not string maniuplation facilities at all (substr
etc.), are there?
