1. Starting the myecplise service will show how to remove dederby:
As a person with a slight obsessive-compulsive disorder, it is very uncomfortable for me to have something under the server that I never use.
Finally, I found the solution online, and now I will share it with you. Open configuration\org.eclipse.equinox.simpleconfigurator\bundles.info
in the MyEclipse installation directory and search for derby (should be on line 16) to find com.genuitec.eclipse.derby, 11.0.0.me201211281531, plugins/com.genuitec.eclipse .derby_11.0.0.me201211281531.jar,4,false Comment it out i.e. (#com.genuitec.eclipse.derby,11.0.0.me201211281531,plugins/com.genuitec.eclipse.derby_11.0.0.me201211281531.jar,4 , false) or delete it directly. In this way, MyEclipse will not load this plug-in, similar to removing Derby from the Startup and Shutdown settings in the previous version, but now the 2013 version is no longer available.
2. Myecpise adds multiple services
1. Make a copy of Tomcat and rename it, here I am E:\soft\apache-tomcat-study, then modify the conf/service.xml file and change all the port numbers to something else, so that two startups can start at the same time. When a tomcat is used, it will not cause an error that the port is occupied.
Second, the picture above
3. Right-click new service
4. Add the corresponding tomcat server
5. Modify the specified server path
-Dcatalina.home=D:/tools/instantDir/apache-tomcat-8.5.30-biaoshi-b -Dcatalina.base=D:/tools/instantDir/apache-tomcat-8.5.30-biaoshi-b -Djava.endorsed.dirs=D:/tools/instantDir/apache-tomcat-8.5.30-biaoshi-b/common/endorsed -Djava.io.tmpdir=D:/tools/instantDir/apache-tomcat-8.5.30-biaoshi-b/temp -Djava.library.path=D:/tools/instantDir/jdk8/bin;D:/tools/instantDir/apache-tomcat-8.5.30-biaoshi-b/bin -Dsun.io.useCanonCaches=false
That's basically it
