In the example, a local copy of a DTD called car. Whenever the application is parsing an XML file and it encounters an entity declaration using either one of the IDs, it will substitute the car. You can specify that WebLogic Server cache external entities that are referenced with a URL or a pathname relative to the main directory of the EAR archive, either at server-startup or when the entity is first referenced.
Caching the external entity saves the remote access time and provides a local backup in the event that the Administration Server cannot be accessed while an XML document is being parsed, due to the network or the Administration server being down.
In the example, the car. WebLogic Server caches a copy of the DTD in its memory when it first starts up, and then refreshes the cached copy if it is stored for longer than seconds. Skip Headers. The default value is cache-on-reference. The default value for this field is seconds.
Configuring a Parser or Transformer for an Enterprise Application You can specify that an XML application use a parser or transformer different from the default parser or transformer configured for WebLogic Server by updating the weblogic-application.
MF file as shown: Manifest-Version: 1. Copy the external entity, such as a DTD, to the directory. Configuring the External Entity Cache for an Enterprise Application You can specify that WebLogic Server cache external entities that are referenced with a URL or a pathname relative to the main directory of the EAR archive, either at server-startup or when the entity is first referenced.

A sample listing of an application. After the enterprise application's files are properly arrayed, the application should be archived within an EAR Enterprise Archive file, as shown here:.
In reference to deploying enterprise applications on WebLogic Server: To facilitate hot deployments, WebLogic uses separate class loaders for Web modules deployed within the enterprise application. Therefore, individual Web components cannot see each other's class files. If your Web components modules are using the same files, there are three general strategies to employ using WebLogic Server 8.
Place the common or shared files within an archive at the enterprise application level. You must reference that archive within the manifest files of the application module archives. This file is placed under the enterprise application root directory. Then the manifest. To execute this update, place the Class-Path reference within a text file. Then, using the jar command, execute the following command:.
The target module's archive manifest file will be updated with the classpath attribute. Define a classloader -structure within the application's weblogic-application. The following classloader -structure an excerpt from weblogic-application. There are two other types of applications that may be deployed to WebLogic Server—client applications and resource adaptors—each with associated deployment descriptors.
Deployment descriptors may be generated automatically using the WebLogic DDInit utility as shown here:. Existing deployment descriptors can be edited using the WebLogic Builder application.
Editing deployment descriptors with the WebLogic Administration Console, although still commonly used, has been deprecated in WebLogic 8. Edit selected elements as shown in Figure 7. To promote application security, the web.
