How to generate random strings or number from Jmeter

While testing soap services, most of the time we may need jmeter scripts to generate random string or numbers as a service parameters.
I had a soap service to send the name (string value) and age (integer value) contentiously and each value should not be repeatable need to be random unique values. I used Random and RandomString functions to generate these values. Following Jmeter scrips may help you to do that.

Please find the SOAP/XML RPC request which I used here.

 <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:dat="http://ws.wso2.org/dataservice">  
   <soapenv:Header/>  
   <soapenv:Body>  
    <dat:inputOP>  
      <dat:age>${__RandomString(5,ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789,)}</dat:age>  
      <dat:name>${__Random(5,0123456789,)}</dat:name>  
    </dat:inputOP>  
   </soapenv:Body>  
 </soapenv:Envelope>  

It will send SOAP request as below.

 <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:dat="http://ws.wso2.org/dataservice">  
   <soapenv:Header/>  
   <soapenv:Body>  
    <dat:inputOP>  
      <dat:age>X7NQH</dat:age>  
      <dat:name>97593961</dat:name>  
    </dat:inputOP>  
   </soapenv:Body>  
 </soapenv:Envelope>
