Hidden Exceptions

Hi,

given this Action:

public class MyAction {
  public String execute() throws Exception {
        // throws IllegalArgumentException
  }
}

I do not get a log output or anything else indicating that error.

I have struts dev mode = true. Report page shows:
"Struts has detected an unhandled exception:"

At the moment I mostly need to debug to see whats going on.

I would like to get all Exceptions into my logfile. How can I make
sure this happens?

Thanks,
Christian

Cool thanks. This worked for me.

As I don't use a default stack, it was better for me to configure directly:

<interceptor-ref name="exception">
        <param name="logEnabled">true</param>
         <param name="logLevel">ERROR</param>
</interceptor-ref>

Cheers and thanks again, this helped me working with more comfort.

Is it the "exception" interceptor, because OGNL does some magic and calls the

Well, let's see... I am no Struts expert, but one way that I know of to log errors is by using your struts.xml configuration.

Make sure you have something like this in your interceptors:

<interceptors>
	<interceptor-stack name="appDefaultStack">
		<interceptor-ref name="defaultStack">
			<param name="exception.logEnabled">true</param>
			<param name="exception.logLevel">ERROR</param>
		</interceptor-ref>
	</interceptor-stack>
</interceptors>

<default-interceptor-ref name="appDefaultStack" />

Then, to make sure Struts handles all exceptions, add this below your interceptor section:

<global-results>
	<result name="error">/your_error_page.jsp</result>
</global-results>

<global-exception-mappings>
	<exception-mapping exception="java.lang.Exception" result="error" />
</global-exception-mappings>
