MyEclipse8.5 Integrated TOMCAT7

I recently needed to use TOMCAT7 in MyEclipse, I have configured the local Tomcat path in servers, and then I publish the item, and the following error message appears when I start the Tomcat service in MyEclipse:

Exception in thread "main" java.lang.noclassdeffounderror:org/apache/juli/logging/logfactory

Could not find the main class:org.apache.catalina.startup.Bootstrap. Program would exit.

Starting the Web service separately with D:\WorkSoft\apache-tomcat-7.0.62\bin\startup.bat is OK.

Workaround:
Solve the problem by doing the following: Myeclipse->window->preferences->myeclipse->servers->tomcat->tomcat 6.x-> Laucch->create Launch configuration->classpath->bootstrap entities->add External jars-> Select and add D:\ worksoft\apache-tomcat-7.0.62\bin\tomcat-jjar is OK, as follows:
