public class ExternalContext

extends ServiceMBeanSupport

implements ExternalContextMBean

A MBean that binds an arbitrary InitialContext into the JBoss default InitialContext as a Reference. If RemoteAccess is enabled, the reference is a Serializable object that is capable of creating the InitialContext remotely. If RemoteAccess if false, the reference is to a nonserializable object that can only be used from within this VM.

Constructor Detail

ExternalContext

public ExternalContext()

ExternalContext

public ExternalContext(java.lang.String jndiName,
                       java.lang.String contextPropsURL)
                throws java.io.IOException,
                       javax.naming.NamingException

Method Detail

getJndiName

public java.lang.String getJndiName()

Set the jndi name under which the external context is bound.

Specified by:

getJndiName in interface ExternalContextMBean

setJndiName

public void setJndiName(java.lang.String jndiName)
                 throws javax.naming.NamingException

Set the jndi name under which the external context is bound.

Specified by:

setJndiName in interface ExternalContextMBean

getRemoteAccess

public boolean getRemoteAccess()

Description copied from interface: ExternalContextMBean

Get the remote access flag. If true, the external context is bound using Serializable object that allows the InitialContext to be recreated remotely.

Specified by:

getRemoteAccess in interface ExternalContextMBean

setRemoteAccess

public void setRemoteAccess(boolean remoteAccess)

Description copied from interface: ExternalContextMBean

Set the remote access flag. If true, the external context is bound using Serializable object that allows the InitialContext to be recreated remotely.

Specified by:

setRemoteAccess in interface ExternalContextMBean

getCacheContext

public boolean getCacheContext()

Description copied from interface: ExternalContextMBean

Get the cacheContext flag.

Specified by:

getCacheContext in interface ExternalContextMBean

setCacheContext

public void setCacheContext(boolean cacheContext)

Description copied from interface: ExternalContextMBean

set the cacheContext flag. When set to true, the external Context is only created when the mbean is started and then stored as an in memory object until the mbean is stopped. If cacheContext if set to false, the external Context is created on each lookup using the mbean Properties and InitialContext class. When the uncached Context is looked up by a client, the client should invoke close() on the Context to prevent resource leaks.

Specified by:

setCacheContext in interface ExternalContextMBean

getInitialContext

public java.lang.String getInitialContext()

Get the class name of the InitialContext implementation to use. Should be one of: javax.naming.InitialContext javax.naming.directory.InitialDirContext javax.naming.ldap.InitialLdapContext

Specified by:

getInitialContext in interface ExternalContextMBean

Returns:

the classname of the InitialContext to use

setInitialContext

public void setInitialContext(java.lang.String className)
                       throws java.lang.ClassNotFoundException

Set the class name of the InitialContext implementation to use. Should be one of: javax.naming.InitialContext javax.naming.directory.InitialDirContext javax.naming.ldap.InitialLdapContext The default is javax.naming.InitialContex.

Specified by:

setInitialContext in interface ExternalContextMBean

Parameters:

contextClass, - the classname of the InitialContext to use

setProperties

public void setProperties(java.lang.String contextPropsURL)
                   throws java.io.IOException

Set the InitialContex class environment properties.

Specified by:

setProperties in interface ExternalContextMBean

Following copied from interface: org.jboss.naming.ExternalContextMBean

Parameters:

contextPropsURL, - either a URL string to a jndi.properties type of content or a name of a resource to locate via the current thread context classpath.

Throws:

IOException, - thrown if the url/resource cannot be loaded.

getName

Specified by:

getName in interface ServiceMBean

Overrides:

getName in class ServiceMBeanSupport

initService

public void initService()
                 throws java.lang.Exception

Overrides:

initService in class ServiceMBeanSupport

startService

public void startService()
                  throws java.lang.Exception

Start the service by binding the external context into the JBoss InitialContext.

Overrides:

startService in class ServiceMBeanSupport

stopService

public void stopService()

Stop the service by unbinding the external context into the JBoss InitialContext.

Overrides:

stopService in class ServiceMBeanSupport
