Try downloading the examples using this link:
http://www.eclipse.org/downloads/download.php?file=/eclipse/downloads/drops/R-3.6.2-201102101200/org.eclipse.sdk.examples-3.6.2.zip&url=http://ftp.osuosl.org/pub/eclipse/eclipse/downloads/drops/R-3.6.2-201102101200/org.eclipse.sdk.examples-3.6.2.zip&mirror_id=272
This downloads a zip file that contains many JAR files. The JARS are
for both the compiled stand-alone examples and the source code; the
JARs with source have "-source" in their names. This particular
download is for the Mac but you should be able to run the examples if
you have the SWT libraries for your platform.
If you're able to download this then post the link to the listserv if
you think it's helpful.
Cheers
Chris
