Tomcat Sudden Card master, modify JVM memory

To modify the way Tomcat is in memory:
Modify the Tomcat installation directory \bin\catalina.bat
In
Set java_opts=%java_opts%%logging_config%
This line is preceded by a
java_opts= '-xms512m-xmx1024m '
java_opts= "$JAVA _opts-server-xx:permsize=64m-xx:maxpermsize=256m"

where java_opts= '-xms512m-xmx1024m ' is the size of the memory used to set Tomcat.

-XX:PERMSIZE=64M-XX:MAXPERMSIZE=256M Specifies the memory size of class space (for loading classes)

The Tomcat card owner is mostly a configuration file error

The final access directory is the name of the Webroot in Tomcat, which can be set in Myceclipse etc.
