Folks;

deploying RAP as a .war file again: Having an application which works
flawlessly while running inside the IDE, as soon as I have it deployed to an
application server, I sooner or later stumble across this very error:



java.lang.RuntimeException: java.lang.LinkageError: loader constraint
violation: loader (instance of
org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader) previously
initiated loading for a different type with name
"org/eclipse/core/databinding/observable/Realm"

[...]
root cause

java.lang.Thread.run(Thread.java:619)
[...]


As I manually had to start most of the bundles having the application
deployed to tomcat, I am not sure whether this just is a matter of bundle
start order... Any ideas on that, anyone?

TIA and all the best,
Kristian

did you read the "java.lang.LinkageError in SR1 WAR" thread?

I see, thanks. Different duplicate bundle, same problem it seems. But at
least it is working now... :)

Thanks a bunch,
Kristian
