Re: How to check value of a variable is numeric?

Not really a quick reply but something like that can do it (not tested) :

    <j:set
      var="_exception"
      value="${null}" />
    <j:catch var="_exception">
      <echo>***** Try to clean project</echo>
      <j:set var="_integer_prop"  value="${my.integer.property}"/>
      <j:set var="_integer_obj"  value="${Integer.parseInt
(_integer_prop)}"/>
    </j:catch>
    <j:if test="${_exception1 != null}">
      <fail>my.integer.property (${my.integer.property}) isn't an
Integer</fail>
    </j:if>
    <echo>my.integer.property (${my.integer.property}) is an Integer</echo>

  To reuse it you can hide it in a custom taglib for jelly

       <echo>***** Try to clean project</echo> is a bad cut'n paste ;-)
