That is interesting. I tried using the escapeTick="true" attribute with the s:url, but got an exception:
org.apache.jasper.JasperException: /pages/list.jsp(26,6) Attribute escapeTick invalid for tag url according to TLD A further look at the struts 2 tag reference: http://struts.apache.org/2.1.6/docs/url.html Doesn't indicate that the url tag has such an attribute -- I am using struts 2 version 2.1.6, was that attribute used in other versions? Since you mentioned it, I tried an example, without the escapeTick attribute and the URL now forms like this: http://localhost/MyApp/edit.action?id=69&firstName=colin&lastName=o%27hara Although the tick (or apostrophe) is not escaped, when I retrieve the lastName parameter to have the field pre-populated, the name is rendered correctly. But, you made a good point, are there other ways to escape special characters with attributes, or further manual coding are needed?
