The JavaEE Xperience

In the default WebCenter Portal generated by JDeveloper, anonymous-role is granted “view” privilege on the home page. This may not always be desirable. The portal may not have any public content to put on the home page. In my current project, the entire portal has to be secured and available only to authenticated users. You would imagine this is a straight-forward thing to achieve but it’s not.

To turn off access to home page, I edited the page hierarchy and removed the grants assigned to anonymous-role. Now, when the user attempts to access /faces/oracle/webcenter/portalapp/pages/home.jspx, the user gets redirected correctly to the login page. However, if the user were to use the pretty url /pages_home the server throws a 404 error (perhaps an incorrectly flagged 403?) and the user is left with a very unhelpful error page. The trouble with this is that the user may choose to bookmark after his/her initial login and that bookmark will invariably point at the pretty URL.

There is also another side-effect to this. When the user hits logout, webcenter redirects the user to the current page after logout. Given that faces-config.xml contains a “logout_success” navigation case, I imagined that changing this to point at, say, the login page would work. Alas no. The only way to make this work was to change the Logout link to a goLink with the destination set to “adfAuthentication?logout=true&end_url=\faces\oracle\webcenter\portalapp\pages\login.jspx”.

Oh and this is w.r.t WebCenter 11.1.1.5.

Update: Thanks to Andrejus for an excellent workaround. His technique to solve the Session time-out problem can be applied here too.

When you copy the WebCenter FX skin, the copied skin doesn’t work as expected. Without any changes to the copy, I would expect the skin to render the same as WebCenter FX but it doesn’t. My guess is that the copied skin doesn’t inherit properly from the internal base skin used by WebCenter FX. The only way to overcome this is to copy the contents of the internal skin css into the copied skin. Read the rest of this entry »

With Webcenter PS3, Oracle offers something they term “Round-trip Development” using JDeveloper. Simply put, this enables you to

a) download resources from WebCenter Spaces to JDeveloper
b) edit or extend the resources in JDeveloper
c) Directly upload the resources to the server.
