PermGen Space error when deploying tomcat 7? [duplicate]

Answer 1

More helpful solution is to increase values in JAVA_OPTS variable.
Add next line to your Catalina.bat/Catalina.sh file in bin directory

For Windows (Catalina.bat)

set JAVA_OPTS="-Xms1024m -Xmx10246m -XX:NewSize=256m -XX:MaxNewSize=356m -XX:PermSize=256m -XX:MaxPermSize=356m"  

For Unix (Catalina.sh)

export JAVA_OPTS="-Xms1024m -Xmx1024m -XX:NewSize=256m -XX:MaxNewSize=356m -XX:PermSize=256m -XX:MaxPermSize=356m"
