JBossDetector

public JBossDetector()

Method Detail

detect

public ServerHandle detect(MBeanServerExecutor pMBeanServerExecutor)

Detect the server. A ServerHandle descriptor is returned in case of a successful detection, null otherwise.

Parameters:

pMBeanServerExecutor - a set of MBeanServers which can be used for detecting server informations

Returns:

the server descriptor or null it this implementation cant detect 'its' server.

jvmAgentStartup

public void jvmAgentStartup(Instrumentation instrumentation)

Attempts to detect a JBoss modules based application server. Because getting access to the main arguments is not possible, it returns true in case the system property jboss.modules.system.pkgs is set and the org/jboss/modules/Main.class resource can be found using the class loader of this class. If so, it awaits the early initialization of a JBoss modules based application server by polling the system property java.util.logging.manager and waiting until the specified class specified by this property has been loaded by the JVM.

Specified by:

jvmAgentStartup in interface ServerDetector

Overrides:

jvmAgentStartup in class AbstractServerDetector

Parameters:

instrumentation - the Instrumentation implementation

isJBossModulesBasedContainer

protected boolean isJBossModulesBasedContainer(ClassLoader classLoader)

addMBeanServers

public void addMBeanServers(Set<MBeanServerConnection> servers)

Description copied from class: AbstractServerDetector

Do nothing by default, leaving the implementation optional for each specific detector

Specified by:

addMBeanServers in interface ServerDetector

Overrides:

addMBeanServers in class AbstractServerDetector

Parameters:

servers - servers to add
