Start and close Tomcat correctly
solution:
Possible Solution:
I edited the file "Tomcat50x.server" Under C: /Eclipse/plugins/com.ObjectLearn.jdt.j2ee_3.0.1/servers and change
-Djava.endorsed.dirs = "$ {serverrootdirectory} / bin; $ {serverrootdirectory} / common / endorsed"
TO
-Djava.endorsed.dirs = "$ {serverrootdirectory} / common / endorsed"
In The Following 'tags':
-DJAVA_HOME = "$ {jrePath}" -Dcatalina.base = "$ {serverRootDirectory}" -Dcatalina.home = "$ {serverRootDirectory}" -Djava.io.tmpdir = "$ {serverRootDirectory} / temp" -Djava.endorsed .dirs = "$ {serverrootdirectory} / bin; $ {serverrootdirectory} / common / endorse
and
-DJAVA_HOME = "$ {jrePath}" -Dcatalina.base = "$ {serverRootDirectory}" -Dcatalina.home = "$ {serverRootDirectory}" -Djava.io.tmpdir = "$ {serverRootDirectory} / temp" -Djava.endorsed .dirs = "$ {serverrootdirectory} / bin; $ {serverrootdirectory} / common / endorse
This matches the value used in my catalina.bat file when catalina.bat file. .Auched from the command.
Such Eclipse can start and close Tomcat normally.
2, after extracting the Eclipse, you cannot start normally, the error log in the configuration directory displays the following information:

The JDK version in the environment variable PATH points to the version below 1.4, puts the version path you install, such as D: / jkd142 / bin, you can put it in front of 3, set the Source and Output Path menu: Eclipse
