After eclipse runs the web project, it is saved to workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps by default
Eclipse modify the configuration server startup time
workspace\.metadata\.plugins\org.eclipse.wst.server.core\servers.xml文件
The temporary directory of the tomcat project is generally
workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\webapps\下
jsp temporary file in
your workspace workspace\.metadata\.plugins\org.eclipse.wst.server.core \tmp0 \work\Catalina\localhost\
The temporary directory of the jboss project is generally
under workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp1\webapps\
jsp temporary file in
jboss-4.2.3.GA\server\default\work\jboss.web\localhost\下

When the web project in eclipse is debugged, the project under the cache folder is actually used at runtime .
For example, Eclipse reports an error when running the project, saying that org.hibernate.Session cannot be found. In fact, there is clearly hibernate3.jar in WebAppLibraries.
Export the project to war, deploy it directly under tomcat, normal! Maybe an Eclipse problem!
Open D:\eclipse\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\webapps\myweb and find that there is no hibernate3.jar in WEB-INF\lib!
Delete this folder, and then refresh the project in eclipse.
It should be OK, but no project is generated in the cache directory! After rebuilding and cleaning, it still does not generate!
Then close the project and open it. Remove the item in the server view again, and then add it in again. The cache directory is produced
