A component is a specific type of deployment that is part of a J2EE application (see ApplicationMBean). Typically it is a JAR, WAR, or RAR file that contains application code. Deploying an application is primarily the sum of its component deployments. Components define the target servers for the application. A target may be a server or cluster. Web Applications may also reference Virtual hosts, which in turn define additional server/cluster targets.

This section describes attributes that provide access to other MBeans. For more information about the MBean hierarchy, refer to WebLogic Server MBean Data Model.
List of servers and clusters where this module is currently active. This attribute is valid only for modules deployed via the two phase protocol. Modules deployed with the WLS 6.x deployment protocol do not maintain this attribute. To determine active targets for a module regardless of deployment protocol, use DeployerRuntimeMBean#lookupActiveTargetsForComponent .

You must select a target on which an MBean will be deployed from this list of the targets in the current domain on which this item can be deployed. Targets must be either servers or clusters. The deployment will only occur once if deployments overlap.

This section describes the following attributes:
A priority that the server uses to determine when it deploys an item. The priority is relative to other deployable items of the same type.
For example, the server prioritizes and deploys all EJBs before it prioritizes and deploys startup classes.
Items with the lowest Deployment Order value are deployed first. There is no guarantee on the order of deployments with equal Deployment Order values. There is no guarantee of ordering across clusters.

Optional information that you can include to describe this configuration.
WebLogic Sever saves this note in the domain's configuration
file (config.xml

preserved.
If you create or edit a note from the Administration Console, the Administration Console does not preserve carriage returns/line feeds.

A URI that points to the application module, usually on the Administration Server.
URI can only be set if this is a standalone component; the URI for an application is defined in the application's deployment descriptor.

This section describes the following operations:
Indicates whether component has been activated on a server
Operation Name | "activated" |
Parameters | Object [] { target }
where:
|
Signature | String [] {
"weblogic.management.configuration.TargetMBean" } |
Returns |
boolean
|
You can add a target to specify additional servers on which the deployment can be deployed. The targets must be either clusters or servers.
Operation Name | "addTarget" |
Parameters | Object [] { target }
where:
|
Signature | String [] {
"weblogic.management.configuration.TargetMBean" } |
Returns |
boolean
|
Exceptions |
|
If the specified attribute has not been set explicitly, and if the attribute has a default value, this operation forces the MBean to persist the default value.
Unless you use this operation, the default value is not saved and is subject to change if you update to a newer release of WebLogic Server. Invoking this operation isolates this MBean from the effects of such changes.
To insure that you are freezing the default value, invoke the
restoreDefaultValue
operation before you invoke
this.
This operation has no effect if you invoke it on an attribute that does not provide a default value or on an attribute for which some other value has been set.
Deprecated.
Operation Name | "freezeCurrentValue" |
Parameters | Object [] { attributeName }
where:
|
Signature | String [] {
"java.lang.String" } |
Returns |
void
|
Exceptions |
|
Returns true if the specified attribute has been set explicitly in this MBean instance.
Operation Name | "isSet" |
Parameters | Object [] { propertyName }
where:
|
Signature | String [] {
"java.lang.String" } |
Returns |
boolean
|
Operation Name | "refreshDDsIfNeeded" |
Parameters | Object [] { }
where: |
Signature | String [] {
"[Ljava.lang.String;" } |
Returns |
void
|
Removes the value of the addTarget attribute.
For more information, see:
Operation Name | "removeTarget" |
Parameters | Object [] { target }
where:
|
Signature | String [] {
"weblogic.management.configuration.TargetMBean" } |
Returns |
boolean
|
Exceptions |
|
If the specified attribute has a default value, this operation removes any value that has been set explicitly and causes the attribute to use the default value.
Default values are subject to change if you update to a newer
release of WebLogic Server. To prevent the value from changing if
you update to a newer release, invoke the
freezeCurrentValue
operation.
This operation has no effect if you invoke it on an attribute that does not provide a default value or on an attribute that is already using the default.
Deprecated.
Operation Name | "restoreDefaultValue" |
Parameters | Object [] { attributeName }
where:
|
Signature | String [] {
"java.lang.String" } |
Returns |
void
|
Exceptions |
|
Restore the given property to its default value.
Operation Name | "unSet" |
Parameters | Object [] { propertyName }
where:
|
Signature | String [] {
"java.lang.String" } |
Returns |
void
