First: configure eclipse running server: we configure tomcat7 version + JDk1.7 version; Then add the previous Web project to the server
Because our previous project NetWatcher was based on DynamicWebProject selection developed based on tomcat8+jdk1.8
“We chose version 3.1; It will not run on JDk1.7 + Tomcat7
At this point we need to change the configuration of the project: reduce the Java version to 1.7 in the Eclipse interface; DynamicWebM version reduced to 3.0 However, the interface can only modify the Java version, not the Dynamic version, we need to go to the project source file, modify the configuration file under the. Settings folder
