Problem with File Input Output with Jelly,Ant,Maven1

Hi,

I have a problem. I want to read the content of a file. If a special string
is in the file, then I want to go further. If not I want to write the string
in the file.

Does anyone have an idea how I should realize this ?

I begin with 
  <goal name="filetest">
   <util:loadText file="test.txt" var="content"></util:loadText>
   <ant:if test="${content.contains('special string;')}"> 
   	<echo>gut</echo> 
   </ant:if> 
   </goal>

please help me

I don't think you can check for string content like that; the following 
works for me (you'll need commons.lang on your classpath):

   <goal name="filetest">
     <util:loadText file="test.txt" var="content"></util:loadText>
     <j:invokeStatic className="org.apache.commons.lang.StringUtils" 
method="contains" var="contains">
         <j:arg value="${content}" type="java.lang.String"/>
         <j:arg value="special string;" type="java.lang.String"/>
     </j:invokeStatic>
     <j:choose>
     <j:when test="${contains}">
       <echo>gut</echo>
     </j:when>
     <j:otherwise>
       <echo>schlecht</echo>
     </j:otherwise>
     </j:choose>
   </goal>

HTH,
