RE: [aspectj-users] [newbie] General help needed here.....
|
Ramnivas,
It was limited to the lack of markers in the outline view. While we've been
e-mail back and forth, I went ahead and coded up a simple little .JSP page
to call the Logon_Action via Struts, and I've run into a new problem. As
long as the webapp has an AspectJ nature, I cannot get the webapp to
initialize correctly (unable to create my ActionForm beans, for example).
Also, whenever I try to compile a JSP, I get hot-code replacement errors in
Eclipse, and my instance of Tomcat dies. If I remove the AspectJ nature,
everything seems to work OK (no aspect-related stuff obviously). Until I
can get everything working again (Eclipse + webapp + Struts + AspectJ)
without problems, I can't move forward.
Is anyone running Eclipse 3.0 + Sysdeo Tomcat plugin with AspectJ? I'm
having all sorts of problems...
Thanks.
