My SQL Max Connections error

I am working on a school project involving a MySQL database. We have encountered a problem where when we try to connect to our server we get the following error:

Severe:   Exception while deploying the app [FrienDB-Server]
Severe:   Exception during lifecycle processing
org.glassfish.deployment.common.DeploymentException: Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.5.2.v20140319-9ad6abd): org.eclipse.persistence.exceptions.DatabaseException
Internal Exception: java.sql.SQLException: Error in allocating a connection. Cause: Connection could not be allocated because: User nwong already has more than 'max_user_connections' active connections

We are using our schools SQL server so we do not have access to changing the amount of max connections. I have tried killing connections on MySQL Workbench but that does not work. How can we fix this please help!
