Exception in thread "RMI RenewClean-[127.0.1.1:39370]" 

java.lang.OutOfMemoryError: PermGen space

Add it to Server startup arguments:

You may use 1024M if you have enough RAM:

-XX:MaxPermSize=512M -XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled

Note from Eclipse console:

• Use CMSClassUnloadingEnabled in place of CMSPermGenSweepingEnabled in the future

Enable MySQL remote connections

sudo perl -pi -e 's?bind-address = 127.0.0.1?bind-address = 0.0.0.0 ?g' /etc/mysql/tomcat-users.xml

Set Tomcat mgmt interface password

sudo perl -pi -e 's?</tomcat-users>?<role rolename="manager-gui"/>\n<user username="ENTER_USERNAME_HERE" password="VERYSECRET_PASS_WORD" roles="manager-gui"/>\n</tomcat-users>?g' /etc/tomcat7/tomcat-users.xml

Copy MySQL connector DLL to VPS Tomcat 7 folder

scp 'WebContent/WEB-INF/lib/mysql-connector-java-5.1.21-bin.jar' USERNAME@IP_OR_HOSTNAME:/usr/share/tomcat7/lib

scp 'WebContent/WEB-INF/lib/mysql-connector-java-5.1.21-bin.jar' USERNAME@IP_OR_HOSTNAME:/usr/share/tomcat7/lib

See JAVA console output on VPS

cd /var/log/tomcat7

Exception occurred during code generation for the WSDL java.lang.NullPointerException

Want to generate Web Service skeletons using Eclipse and Axis2 (v1.6.2)?
Don't use extra folder levels relative to Eclipse workspace folder - it's not going to work.

OK
Eclipse_workspace\Eclipse_project_folder...

ERROR
