This section includes the following topics:
A JAR (Java ARchive) is a zipped file that contains a set of Java classes. It is used to store compiled Java classes and associated metadata that can constitute a program. A JAR acts like a callable program library for Java code elements (so that a single compilation link provides access to multiple elements, rather than requiring bindings for each element individually). To learn more about JARs, see http://java.sun.com/docs/books/tutorial/deployment/jar/
JAR resources in BEA AquaLogic Service Bus are used in:
To learn more about Java Callout, see Java Callout
The following table lists the JAR pages you can access from the Resource Browser and Project Explorer modules. The tasks and help topics associated with each are also provided.
The Summary of JARs page allows you to view a list of JAR (Java ARchive) files. A JAR is a special Java container file that acts like a callable program library for Java code elements. To learn more, see Overview of JARs.
The unique name assigned to the JAR. The name is a link to the JAR Details page. To learn more, see Viewing and Changing a JAR.

The path is the project name and the name of the folder in which the JAR resides. It is a link to the project or folder that contains this resource. To learn more, see Viewing Project Details or Viewing Folder Details.

Click the Delete icon to delete a specific JAR. To learn more, see Deleting a JAR.
|
Note: | This search supports wildcards. For example, you can enter "j*" in the Name field to get a list of JARs that start with "j". |
Note: | After a search operation, click View All to display all JARs again. |
The Create a New JAR Resource page allows you to add a new JAR (Java ARchive) file. A JAR is a special Java container file that acts like a callable program library for Java code elements. To learn more, see Overview of JARs.
Note: | Click the name of a folder to select it. The Folder View page is displayed. |
The Project View or Folder View page is displayed. The new JAR is included in the list of resources. If the JAR loads without problems, the contents of the JAR will be available for viewing. To learn how to view JAR details, see Viewing and Changing a JAR.
Note: | The new JAR resource is saved in the current session. When you have finished making changes to this configuration, from the left navigation pane, click Activate under Change Center. The session ends and the configuration is deployed to run time. Alternatively, click Discard at any time during the session to delete the changes you have made so far in the current session. |
The View JAR Details page allows you to update a JAR (Java ARchive) file. Updating a JAR essentially involves pointing the resource to a new version of the JAR, as you cannot really edit a JAR usingAquaLogic Service Bus. A JAR is a special Java container file that contains Java classes and their dependencies. To learn more, see Overview of JARs.
The number of objects that reference this JAR. If such references exist, click the link to view a list of the objects. To learn more, see Viewing References.

Note: | The JAR resource is updated in the current session. When you have finished making changes to this configuration, from the left navigation pane, click Activate under Change Center. The session ends and the configuration is deployed to run time. Alternatively, click Discard at any time during the session to delete the changes you have made so far in the current session. |
WARNING: | If you change the JAR used by an EJB Business Service (point the JAR resource to a new version of the JAR), you need to redeploy the EJB. You will then have to edit any EJB service that uses this JAR, and reselect the JAR resource, save, and activate. That will repackage the EJB business service to use the new JAR. |
WARNING: | Java Callout and Tuxedo-based services, however, will automatically pick up the new JAR. |
The Summary of JARs page allows you to delete JAR (Java ARchive) files. A JAR is a zipped container file that stores compiled Java classes and associated metadata.
To learn more, see Overview of JARs.
Note: | You cannot delete a resource if it is referenced by other resources in AquaLogic Service Bus. Instead of the Delete icon, a Delete icon with a red X is displayed for these resources. |
The JAR is removed from the list.
Note: | You can undo the deletion of this resource. To learn more, see Undoing a Task. |
The JAR resource is deleted in the current session. When you have finished making changes to this configuration, from the left navigation pane, click Activate under Change Center. The session ends and the configuration is deployed to run time. Alternatively, click Discard at any time during the session to delete the changes you have made so far in the current session.
