You need to configure Tomcat to not redeploy the application when changing WEB-INF/classes. Create <your_application>/WebContent/META-INF/context.xml: | <Context debug="0" reloadable="false"> | </Context> | or add the attribute reloadable="false" if you already have context.xml. You also can change Tomcat's global context.xml (TOMCAT_HOME/conf/context.xml). As to "Merge all dependent projects into the WEB-INF/classes folder", I think that the Tomcat adapter doesn't support it. The Tomcat adapter is a WTP adapter and isn't related to JBoss Tools. JBoss Tools adapters support this feature for Web and EJB projects (they are deployed in an exploded form and are hot swappable).
