Re: What may cause ognl.InappropriateExpressionException warning ?

Dear all, I'm using struts 2.1.8 with displaytag 1.2 and, of course, I have the same problem. Have you found a solution ?

try adding quotes around it 'd-6836677-p' then it will be interpreted as a string, or try to ignore it in the params interceptor.

Dealing / determining lost session in Struts application

Hi, I'm tasked with killing a bug related to session management and Struts 1.3.10 in a rather conventional JEE web application. The problem is that after the session times out, the application throws a rather ugly exception, something like: 2009-11-04 11:45:46,803 ERROR de.mypackage.ipad.util.hibernate.HibernateFilter - An Exception occured. javax.servlet.ServletException: BeanUtils.populate at org.apache.struts.util.RequestUtils.populate(RequestUtils.java:1254) at org.apache.struts.action.RequestProcessor.processPopulate(RequestProcessor.java:821) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:254) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1482) at... What I understand is that after the session is gone, the internal Struts processing tries to put some data into session-stored objects. It does so with help of Apache BeanUtils and I'm aware that this will crash, of course. My goal is to present a page with a clean message that the session is gone and the user has to re-enter the application. Catching the ServletException at application level (via web.xml) is a bad idea because of the rather generic exception thrown. My current take is that I need a filter which is called before the Struts servlet is called and the filter checks the session beforehand via standard Java API (isNew()). For a new session the user is redirected to a descriptive error page. This might work if the user is already in the application and takes a break, but isNew() will return true at the first entry as well which is nonsense, of course. What is the best practice to deal with this problem for a Struts 1.3 application? Or is this not a standard problem and the cause might be something different?
