You put jar files in the target directory of Eclipse, i.e. in the directory that is generated and populated by Eclipse when building the webapp. So of course, each time Eclipse deploys the webapp, it cleans this directory, and deploys the new version.

You should put the jar file in your source project tree, under WebContent/WEB-INF/lib. The jars in this directory will be part of the webapp's build path automatically, and will be copied to the target WEB-INF/lib directory at deployment time by Eclipse.
