Constructor Details

JBossDetector

public JBossDetector(int pOrder)

Create a server detector

Parameters:

pOrder - of the detector (within the list of detectors)

Method Details

detect

public org.jolokia.server.core.service.api.ServerHandle detect(org.jolokia.server.core.util.jmx.MBeanServerAccess pMBeanServerAccess)

jvmAgentStartup

public ClassLoader 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 org.jolokia.server.core.detector.ServerDetector

Overrides:

jvmAgentStartup in class AbstractServerDetector

isJBossModulesBasedContainer

protected boolean isJBossModulesBasedContainer(ClassLoader classLoader)

getDetectionTimeout

protected int getDetectionTimeout()

Description copied from class: AbstractServerDetector

If a detector requires an active-wait loop, this is the total timeout (in ms). If -1, it means the waiting is disabled. But given detector has to actively invoke waiting code.

Overrides:

getDetectionTimeout in class AbstractServerDetector

Returns:

getDetectionInterval

protected int getDetectionInterval()

Description copied from class: AbstractServerDetector

A wait (in ms) between active-loop waiting cycles.

Overrides:

getDetectionInterval in class AbstractServerDetector

Returns:

getMBeanServers

public Set<MBeanServerConnection> getMBeanServers()

Description copied from class: AbstractServerDetector

Specified by:

getMBeanServers in interface org.jolokia.server.core.detector.ServerDetector

Overrides:

getMBeanServers in class AbstractServerDetector
