I very new to struts and I am learning under fire. I have all the parts working now but I am unable to present the information to the screen. I am a little fuzzy on this part of the application. I am not sure I have the mappings right. Can someone be so kind to point out my issue?
Eclipse version: 3.1.1
workbench version: 4.1
Application server: JBoss4.0.3SP1
Struts verion: what ever comes with workbench

The way struts works is when you visit a page with a .do (or whatever mapping you made it) extension, ActionServlet rips off the .do extension, then tries to match the remaining name, in this case “AddCatalogEntry” to an entry in your struts-config.xml file. Unfortunately you don’t have an entry with that name, you only have: path=”/AddJournal”
so you either need to change the name of your action-mapping or add a new mapping that will match against the form’s name. Or just change the target of your form.
That did it…….fixed right the first time…… Just changed the path name to /AddCatalogEntry and every thing worked just right……..
Thank you!
