When running a Jython script to control the state of an Application Deployed to a Standalone Liberty Profile server, we get the following error: TypeError: javax.management.remote.JMXServiceURL(): 3rd arg can‘t be coerced to int

The reason for this is the line of code in the Jython script that create a connection to the Liberty Server’s JMX interface (WebSphere:service=com.ibm.websphere.application.ApplicationMBean,name=*) is a string not an int i.e. the port number was passed as string not int

 

def getConnection(trustStore, trustStorePassword, hostname, port, username, password) : JMXRESTConnector.trustStore = trustStore JMXRESTConnector.trustStorePassword = trustStorePassword connector = JMXRESTConnector() connector.connect(hostname, port, username, password) mconnection = connector.getMBeanServerConnection() return mconnection #endDef

1 2 3 4 5 6 7 8 9

def getConnection(trustStore, trustStorePassword, hostname, port, username, password) :     JMXRESTConnector.trustStore = trustStore     JMXRESTConnector.trustStorePassword = trustStorePassword          connector = JMXRESTConnector()     connector.connect(hostname, port, username, password)     mconnection = connector.getMBeanServerConnection()     return mconnection #endDef

The code was changed from

 

_mBeanConnection = getConnection( trustStore, trustStorePassword, hostname, port, username, password)

1 2 3 4 5 6 7

_mBeanConnection  = getConnection(                 trustStore,                 trustStorePassword,                 hostname,                 port,                 username,                 password)

to

 

_mBeanConnection = getConnection( trustStore, trustStorePassword, hostname, int(port), username, password)

1 2 3 4 5 6 7

_mBeanConnection  = getConnection(                 trustStore,                 trustStorePassword,                 hostname,                 int(port),                 username,                 password)
