@Amar N ,

Yes, It's possible. It does support substring extraction from a string. For more details reger policy documentation here.

For Example, below pattern will extract substring from queryparam. If queryparam value is "DBN001" then code extracted will be 001.

   <QueryParam name="code">
      <Pattern ignoreCase="true">DBN{dbncode}</Pattern>
   </QueryParam>

Keep us posted if you have any queries.

Hi ,

Can you give an example for raise fault policy, how we can substring error fault string to extract specific information.

Yes it is possible only when the sub string is varying and the main string except supstring is constant.

So, if the entire string is varying and we would only like to extract for example the last 5 digits of a 8 digit queryparam, it is not possible?
