Hi "lacd" ... your question is a common one. The only answer is to dump all the GeoTools jars into the same plugin, GeoTools uses Java's Factory Service Provide Interface (ie FactorySPI) plugin system in which it looks up stuff on the classpath.
Eclipse RCP uses some scary classloader tricks that interfere with this. For more information on FactorySPI: - http://docs.codehaus.org/display/GEOTDOC/How+to+Find+a+Factory For a working example of how to do this check out the uDig project. And before you ask the "buddy classloader" trick wont work - it lets plugin share a classloader but it does not let a buddy provided a META_INF/services/ directory full of text files (which is what factory spi wants to see).
