1, the first method: Modify the Tomcat/bin directory Catalina.bat.
2. Join under "REM-----Execute The requested Command----------------------"
java_opts= "-server-xms800m-xmx800m-xxnewsize=256m-xx:permsize=256m-xx:maxnewsize=512m-xx:maxpermsize=512m" .
This approach works when you use Tomcat only, but it doesn't work when you use Eclipse.
3, the second method: Modify the Eclipse.ini.
4. Join
-vm
D:/jdk6/bin/javaw.exe
-vmargs
-dosgi.requiredjavaversion=1.5
-xms512m
-xmx1024m
-xx:permsize=256m
-xx:maxpermsize=512m
This method sometimes works, but this time it does not work, the specific reasons I do not know, I guess it may be written above this paragraph with the launch of the Tomcat server in eclipse does not matter, so can not solve the problem of Tomcat error.
5. Third method: Modify Eclipse's Run configurations.
6. Click "Run"-"Run Configurations" and click on the "Arguments" tab in the window that opens.
7. In VM arguments, enter the bottom of the content:
-xms256m-xmx512m-xx:maxnewsize=256m-xx:maxpermsize=256m
8, after the re-restart after the save is no longer an error. It was this method that solved my problem in good condition.
