Eclipse RCP OSGi Conflict org.mortbay.jetty

Question

When starting my Eclipse RCP application, I experience the following error:

!MESSAGE Bundle org.eclipse.equinox.http.jetty_2.0.0.v20090520-1800 [154] was not resolved. !SUBENTRY 2 org.eclipse.equinox.http.jetty 2 0 2013-01-21 17:31:55.618 !MESSAGE Package uses conflict: Import-Package: org.mortbay.jetty; version="[6.1.0,7.0.0)"

This leads to the problem, that within the RCP application, the help system cannot be started (due to a ClassNotFoundException).

As far as I understand it, there is some problem with the bundle org.mortbay.jetty in the sense that it is present in a wrong version, or multiple incorrect versions. So I started my Eclipse RCP application with the program argument -console in order to get an OSGi console.

I type

osgi> packages org.mortbay.jetty

to find out about all imports and exports of this package. Which gives me the following result:

org.mortbay.jetty; version="6.1.15"<org.mortbay.jetty.server_6.1.15.v200905151201 [491]>

But this seems okay to me. Obviously, org.mortbay.jetty is exported by org.mortbay.jetty.server and it's exported version is 6.1.15, which is in the range of [6.1.0,7.0.0). Furthermore, when my colleagues try to start the application, they encounter no problem whatsover.

I also tried to use a fresh workspace for the RCP application but that didn't help as well ... I'm really clueless now ...

Answer 1

Problem is fixed, within the launch configuration some important plug-ins were not checked to be launched. In fact, I needed to switch from a feature-based configuration to a plug-in-based configuration.

Answer 2

i was having same problem some time back with jetty.

solution:

1) if u r using plug-in based eclipse rcp application -> remove the plugin version (major/ major) or

2) if you are using feature based rcp application --> make sure set match="compatible"
