Weblogic Server Tutorial Pdf

In this chapter, we will introduce you to the basics of WebLogic Server, with terms and concepts that Various ways to use WebLogic Server as an HTTP server. WebLogic Server supports the following Web Service standards. – JAX-WS – JAX-RPC – Web Services for Java EE – Web Services Metadata. Oracle WebLogic Server: the Administration Console, the Node Manager Oracle WebLogic Server 11g is a component of Oracle Fusion Middleware 11g.

She has spoken at lots of conferences. Her hobbies include reading, completing puzzle books and cycling. Recently I have also spent a lot of time studying the cloud and thought it might be useful to create some guides on how to use various cloud platforms with the NetBeans IDE. This tutorial assumes that you have your Java Cloud service set up and want to be able to test applications locally and deploy to the cloud server. We will be using the Weblogic 12c server both locally and on the Java Cloud Service. I use a Windows system so any commands or steps ma slightly differ for other operating systems. What you will need before you start: — Java 7 and 8 JDKs installed. On Windows you can do this by going to your control panel, System and selecting Advanced System Settings. Now open a command prompt and cd into your document and execute the jar using the below command.

That way, unicast is more of a private conversation between two individuals while multicast is more of a shout to a group or room. But Unicast can span across routers and does not have to worry about TTL without the everyone hearing the announcement.

So, Network Admins in general prefer to go with Unicast over Multicast for these reasons. At the time of the creation of domain, the wizard for setting configuration asks for the details like user name, password etc.

If the domain is created in development mode, the configuration wizard saves the encrypted password as well as the username inside an identity file. This file is available for reference during the time of booting so that in the absence of this file, system can prompt the user for the purpose of entering credentials.

A new boot — identity file can be created if you want to change the use credentials or else if you are having the requirement of creating domain in the production mode.

WebLogic Server installs the following script that you can use to set the classpath that a server requires: WebLogic Server uses two mechanisms to determine if a given server instance is unavailable.

By monitoring heartbeat messages, server instances in a cluster determine when a server instance has failed. The other server instances will drop a server instance from the cluster, if they do not receive three consecutive heartbeats from that server instance WebLogic Server also monitors socket errors to determine the availability of a server instance.

For example, if server instance A has an open socket to server instance B, and the socket unexpectedly closes, server A assumes that server B is offline.

Clustering is the process of grouping the servers together for accomplishing high percentage of scalability and availability. The major goal of performing the process of clustering is to make high scalability as well as availability of the servers possible. This process also helps in balancing the load in a proper manner and also accomplishes failover. The communication through cluster is made possible by the multicast IP as well as port by the process of sending periodic messages which are normally called as heartbeat messages.

Oracle bought Weblogic from BEA. This utility is used to apply the WebLogic Server Patches. The usual process is that in case of any difficulty for the manager server to get connected to any administration server at the time of start up, there is an option for the managed server to retrieve the configuration related to it from the configuration files as well as other files involved.

The information thus retrieved cannot be altered and it is possible only when the administration server is really available.

When the administration server is unavailable, then the managed server enters into its independence mode for carrying out its operations.

There are two modes Development mode: You use development mode while you are developing your applications.

Development mode uses a relaxed security configuration and enables you to auto-deploy applications. Production mode: You use production mode when your application is running in its final form. A production domain uses full security and may use clusters or other advanced features. There are two method of clustering Horizontal and Vertical.

Horizontal clustering: Horizontal scaling is more reliable than vertical scaling, since there are multiple machines involved in the cluster environment, as compared to only one machine Vertical clustering: There are three starting modes are available: Administration Server copies the deployment files from their original location on the Administration Server machine to the staging directories of each target server 2 External Stage: The Administration Server does not copy deployment unit files; instead, all servers deploy using the same physical copy of the deployment files, which must be directly accessible by the Administration Server and target servers.

A Java thread dump is a way of finding out what every thread in the JVM is doing at a particular point in time. This is especially useful if your Java application sometimes seems to hang when running under load, as an analysis of the dump will show where the threads are stuck. The enhancements support for WebLogic Server messages is provided by T3.

T3 is superset of java Object. Serialization and RMI can be done over T3. By default, if a Managed Server is unable to connect to the specified Administration Server during startup, it can retrieve its configuration by reading a configuration file and other files directly.

A WebLogic Server cluster consists of multiple WebLogic Server server instances running simultaneously and working together to provide increased scalability and reliability.

A cluster appears to clients to be a single WebLogic Server instance. The server instances that constitute a cluster can run on the same machine, or be located on different machines. Each server instance in a cluster must run the same version of WebLogic Server. WebSphere MQ Real-time Transport is a lightweight protocol optimized for use with nonpersistent messaging.

WebSphere MQ Real-time Transport is ideal for applications where large numbers of messages need to be sent or where messages need to be sent to large numbers of client applications. The WebSphere MQ Real-time Transport does not provide any facilities for persistent messaging or durable subscriptions.


Ant is an open source project available under the Apache license. Therefore, its source code can be downloaded and modified. Additionally, Ant uses XML build files which make its development easy. Cross Platform: Use of XML along with Java makes Ant the perfect solution for developing programs designed to run or be built across a range of different operating systems.

New tasks are used to extend the capabilities of the build process, while build listeners are used to help hook into the build process to add extra error tracking functionality. As Ant is extensible and open, it can be integrated with any editor or development environment easily. An application-specific XML-based deployment descriptor file named web.

Each J2EE module is a collection of one or more J2EE components of the same container type Web or EJB that are represented by one component deployment descriptor for that type in the web. A WebLogic-specific deployment descriptor file named weblogic.


Examples of weblogic. When you upgrade a domain to WebLogic Server 8. For server-side applications, JRockit has these advantages over other virtual machines:. It employs adaptive optimization, which detects and removes bottlenecks in the deployed application.

It is designed specifically for the special requirements of server-side applications, which tend to be parallel and thread-intensive, to run for longer periods of time, and not to use graphical interfaces. For example, change:. Remove from server start scripts any switches specific to the Sun JVM. For example, from the start command:. Then choose the driver type for the DB. Give the connection pool name. After successful connection, it will ask you to create and deploy the connection pool target to server or cluster.

After creating new connection pool always point the jdbcstore to the connection pool created. After each JDBC connection, we have to restart the server if there is startup classes dependancy exists otherwise no restart required in WebLogic 9. A naming service associates names with objects and finds objects t3 protocol will be used. The RMI registry is a good example of a naming service. These naming services maintain a set of bindings, which relate names to objects and provide the ability to look up objects by name.

JNDI allows the components in distributed applications to locate each other. WebLogic clustering offers three important benefits: The capacity of an application deployed on a WebLogic Server cluster can be increased dynamically to meet demand.

Ok, I'm late, but I'm going to share the two tutorials I'm following, since I would have found helpful to have those right away.

WebLogic is a complex, enterprise-level product. I believe Oracle is making a pretty good attempt at explaining it in the intro doc: You can follow the links to get to the detailed documentation of the features that interest you.

If that's not to your liking, site has books like e. It depends a lot on your app, but if you can deploy it in tomcat, I'd be surprised if you couldn't deploy it in WebLogic.

Having said that, I certainly hope you have a good reason for using WebLogic and I hope that reason isn't "The sales guy said it's awesome".

In my admittedly limited experience with WebLogic, I've found it to be a huge pain to use and impossible to troubleshoot if something goes wrong and it will go wrong. On the other hand, I have lots of experience with Tomcat, which is dirt-simple to use and easy to troubleshoot not that you need to troubleshoot, since it pretty much just works. The results are in! See what nearly 90, developers picked as their most loved, dreaded, and desired coding languages and more in the Developer Survey.

Any decent weblogic tutorial? Thanks in advance. Tom Tom Can you provide more details about the topics you would like to see covered? J2EE is pretty wide and I don't think you'll find an all-in-one tutorial on Weblogic.

Being a bit more specific e. Eugenio Laghi Eugenio Laghi 1 6 Can you share if you have? Sten Vesterli Sten Vesterli 2, 1 17 Seth Seth Please tell me why you would get more problems on Weblogic and why it would be harder to troubleshoot than Tomcat.
