Error: java.lang.NullPointerException - My Appointments iView

7 Views

Good evening.

I configured the Microsoft Exchange connectivity using WebDAV

Transport, with the following procedure:

1.Publish the Custom Form provided by SAP.

2.Create and configure a WebDAV Transport.

3.Configure the Calendar Repository Manager.

But, when I execute the following test of connectivity from the portal:

a.Check that the e-mail address is configured for the test user.

b.Choose Personalize ®User Mapping from the portal header, and enter

the user credentials associated with this e-mail address.

c.Select the My Appointments iView by selecting on Content

Administration /Portal Content / Content Provided By SAP /

Collaboration / DemoRole / iViews.

d.Select Preview. The iView should now display appointments for the

current date.

I have the following error:

class java.lang.NullPointerException.
