Install SWT-Examples via "Welcome"-Dialog results in NullPointerEx... [message #1009749] Fri, 15 February 2013 11:24 Go to next message

Because I'm new, this could well be a beginners error so I post it here and not in the dedicated SWT section (hope this is correct):

- Freshly installed Eclipse Juno (Eclipse IDE for Java EE Developers)
- Java JDK 7 update 13 installed
- both 32bit
- win 7 professional (64bit but doesn't matter)


If I click on "Workbench views and standalone applications" in the "Samples" section in the "Welcome" perspective, eclipse gives back a NullPointerException after asking to download and install the samples from eclipse.org.

Alternatively, I tried to install the examples manually, as described here

By:
- using the Update Manager (option 1) -> Failed because no "Eclipse SDK Examples" available for selection (like mentioned in step "5.")...

- downloading the Example Plug-In (org.eclipse.sdk.examples-4.2.1.zip) and unzip'ing it into eclipse/dropins folder as suggested in option 2.

This also doesn't work. The linked site suggests:

Quote:
You can verify that examples have been installed by looking for File > New > Example... in the workbench menu bar.


Unfortunately,
- there are no new examples available via that menu.
- the site does not make any suggestions how to trouble shoot this issues...


Any suggestions?

Thx
Martin

I have the same issue. I wonder if a server is currently down or if you and I both have DNS issues with our ISP.

I'm on Mac OS X 10.8 with Java 1.6.0_37

java.version=1.6.0_37
java.vendor=Apple Inc.

Command-line arguments: -os macosx -ws cocoa -arch x86_64 -product org.eclipse.epp.package.jee.product -keyring /Users/admin/.eclipse_keyring -showlocation
