Suman,
The jars from buildpath would have been packaged into the WAR file.
Please modify workspace preferences. Go to: Window > Preferences > MyEclipse > Java Enterprise Projects > Web Project. Here you should uncheck option “JARs from the build path”. This should prevent MyEclipse from packing runtime (and any other from the classpath) Jars into WAR.
However, in case, that you have some others jars attached to the build path, you have two options:
1. You can use “Deployment assembly” to specify what and where should be packed into war (Project > Properties > MyEclipse > Deployment Assembly)
2. You can create User Library for the jars. Go to: Window -> Preferences -> Java -> Build Path -> User Libraries, configure User Library and add it to project path (Project -> Properties > Java build path -> Libraries -> Add library -> Select User library). Go once again to Deployment Settings (Window > Preferences > MyEclipse > Java Enterprise Projects > Web Project) and uncheck “Jars from users libraries” and “User library jars exported from dependent java projects” making sure, that two others are checked, in that case.
Let us know how this works for you.
