after I download spring rcp in the folder spring-richclient-1.1.0\samples\
I find some jars with official examples.
But when I try start one of them:
java -jar spring-richclient-samples-showcase-1.1.0.jar

I get the next error:
Code:

when I try another example jar
java -jar spring-richclient-samples-dataeditor-1.1.0.jar

I get the another error:
Code:
Failed to load Main-Class manifest attribute from
spring-richclient-samples-dataeditor-1.1.0.jar
Why official examples NOT work?
