Mobile Support Issues and Workarounds

This section describes mobile related issues and their workarounds for Oracle9iAS Portal.

5.1 Non-NLS Messages

There are two messages which are not translated into any language other than. These appear in the following cases:

5.2 Navigation Restriction for Nested Page Portlets

A mobile device can be used to access a portal page containing a page portlet within another page portlet. However, when navigation occurs into the inner page portlet, it may not be possible to navigate back, without going back to the Home page.

The 'Back link' context is lost when page portlets are nested on mobile pages and when viewing a standard page on a mobile device.

5.3 Problems with Portal Redirects on Openwave Simulators

There is a problem with Openwave Simulators (version 4.1 and 5) which prevent some HTTP redirects from being performed by the simulator.

5.4 Design Restrictions of Page Portlets

5.5 IP Cookie Validation Failure

Some proxy server configurations may cause cookie validation to fail. This problem which will probably only be observed when Portal is being accessed from outside an intranet (i.e. from a mobile device), causes "Invalid Session" errors to appear in the client. To fix this, disable the IP checking stage of cookie validation by entering the SQL detailed earlier in Chapter 3 Disabling the IP Check of Cookie Validation.

5.6 Portlet Link Mode and Mobile Page Preview

Although portlets can render any Oracle9iAS Wireless XML when requested to render in Link mode, "well behaved" portlets only ever respond with a single SimpleHref element. Such responses are the only ones that are formally supported by Oracle9iAS Portal.

5.7 Error Logging

Some errors originating from Oracle9iAS Portal cannot be rendered directly into a mobile browser. In such cases the errors are written to the servlet log and a general error message (with unique ID) are written to the client device.

5.8 _debug Output

Performance related output for mobile requests when using the URL parameter _debug=[01] is written to the servlet log, not to the mobile browser.

5.9 Some Dialogs Refer to Tabs Instead of Levels

Some dialogs displayed in the mobile page design time environment refer to 'tabs'. However, these references should be to 'levels'.

5.10 Moving Levels in Mobile Page Edit Not Possible

Currently, it is not possible to move levels within other levels (this is a limitation of the standard page UI with regards to moving tabs).

5.11 Limitations of Mobile Page Viewer

Only URL items are displayed in the mobile view of a page. Other types of items (Text, File, etc.) are not displayed. This restriction will be removed in a future release.

5.12 Permission Related Error Message Hidden from Mobile Clients

When a user using a mobile client attempts to access a non-public page for which they have not been granted view privileges, the standard error message is raised:

wwpob_api_page.show: You do not have permission to perform this operation

Rather than being sent to the user, though, this message is trapped by the Parallel Page Engine. The Parallel Page Engine records the error message in the servlet's log file and sends the following message to the mobile client:

A temporary error has prevented Oracle Portal from servicing your request.  
(id=nnnnn)

where nnnnn is a unique id that can be used to look up the logged error in the servlet's log file. This error message is used whenever the Parallel Page Engine traps error messages that cannot be properly handled by mobile clients, but, in this case, the error is benign - it is just a privilege issue.

To find mobile related errors that have been logged in the Parallel Page Engine's log file, search for (log errorID = nnnnn), where nnnnn is the number reported in the mobile client.

To avoid running into this problem too often, ensure that any default home page is accessible by the users intended to make use of it as a home page.
