MyEclipse WebSphere Overview (bottom)

In the WebSphere Overview (top) Article, the small section describes the MyEclipse, WebSphere & RAD, MyEclipse Workbench, Project types common in MyEclipse, and WebSphere descriptor file editors. The next small series will introduce you to a few other sections, hoping to help everyone.

5. Deployment Project

In MyEclipse, you deploy or publish the project to the application server. To run or debug a project you can choose to configure an application server on MyEclipse to deploy your project, and then run the application server. Before discussing deployment, however, there are a couple of concepts you must know about the available deployment options.

5.1 Deployment Model

The selected WebSphere Deployment mode determines whether a generic deployment mode is selected. The WebSphere Deployment mode is set in the WebSphere server configuration file. When you deploy a module to the server, you select the general deployment mode.

WebSphere Deployment Mode

Classic Mode : When you deploy a project to a server, either the exploded deployment or the encapsulated deployment can be a choice for you.

in-workspace Mode : This is the default setting and does not provide a general deployment mode for selection. This pattern is a hybrid decomposition deployment pattern. This mode deploys the ear file from the location of the workspace, rather than being copied to the location of the WebSphere configuration file. This is the fastest deployment mode, but can only be used in an ear project. Synchronization of resources and code is handled directly by WebSphere. This mode is best for debugging fast-growing applications.

General Deployment Mode

Split Deployment (development mode): This is a development-centric, but non-standard JEE application encapsulation deployment pattern. Similar to encapsulating deployment, the application's deployment resources are organized in a folder/file structure that conforms to a JEE standard. But instead of creating and not a single archive, the entire application resource structure-folders and files-is replicated to the special location of the Decomposition archive server through the application server. The MyEclipse deployment server uses "synchronous-on-demand technology" to keep all source code changes and MyEclipse project deployments synchronized for all MyEclipse projects.

Encapsulation Deployment (build mode): This is deployed in a build-centric JEE standard application encapsulation pattern. It contains a single zip archive of encapsulated application resources with an internal JEE categorization malleability file structure. The resulting single archive file is then deployed to the target application server through the Application Service connector. An encapsulated archive deployment does not support incremental or automatic archive updates. Therefore, the encapsulation deployment is not synchronous, and its source project is edited for project resources. The latest version of the MyEclipse project source code is periodically released to deploy application state synchronously.

5.2 Managing deployments

There are several ways to deploy a project:

• Drag an item to the server in the server view
• Right-click an item and select Myeclipse>add and Remove project deployments
• Click the Manage Deployment icon on the main toolbar
• Right-click the server in the server view and select Add/remove deployments
• Click the Add/remove deployments icon on the toolbar of the server view

To deploy a project from the main toolbar deploy the project from the Server View toolbar

By default, the drag-and-drop method is used to quickly add items to the exploded server. You can change the default deployment mode for a project in the parameters of the project. Right-click the project and select Properties from the menu. Expand MyEclipse, and then select Server Deployment.

Select the default deployment mode

Use the Manage Deployment icon on the main toolbar to view projects deployed to the server, add or remove deployment projects. You can also publish the selected server to synchronize all deployed projects. You can also set up any number of deployments to any number of servers for a project. You can deploy WebSphere, Tomcat, JBoss, and GlassFish to a single Web project at the same time, and MyEclipse synchronizes all of these deployments.

rad User Note : This is different from IBM RAD, and your project does not depend on the run-time project configuration.

Deployment window for projects

When you add an item to the server, the Add and remove window opens, allowing you to add/remove one or more items.

Adding and removing deployments

The deployment web, EJB, and ear projects are handled in the same way. Use the MyEclipse connector (instead of a third-party server) when adding items to the server. You can control the deployment mode for decomposition or encapsulation. In the Add and remove window, once you have moved it to the configuration list, you can use the drop-down list next to the module to change the default deployment mode. The icon next to the module indicates the deployment mode. For example, a Web module that represents a decomposition, a Web module that represents encapsulation.

Note : If you deploy the project to WebSphere using the In-workspace mode of the default WebSphere deployment mode, the decomposition and encapsulation modes are not applicable.

Change the deployment mode

We encourage developers to actively change projects, stick to decomposition patterns to deploy and test changes, because it makes work easier, but you can choose any kind of deployment you prefer to work with. If you want to speed up deployment, you can disable the EJB project deployment to WebSphere 6.1 or later. To disable EJB deployment, on the Ear property page, you can then run the EJB manual deployment when needed.

To disable EJB deployment for an ear project

Manually deploy the EJB by right-clicking the EJB project and selecting Myeclipse>run EJB deploy.

Deploying EJB Projects Manually

The EJB deployment properties of the ejb2.x project allow you to configure the EJB deployment.

EJB Deployment Configuration6. Run and debug the project

Before reading this section, make sure that you understand the content of section 5th and understand how to handle deployment in MyEclipse. When your project is deployed to an application server, you need to make sure that the application server is running and hosting your project (Web or enterprise application) so that you can run and connect to it. You can manage the configured application server from the toolbar or from the server view.

Managing application servers from the toolbar manage application servers from the Server View toolbar

These controls provide you with the ability to start, stop, and restart the selected application server. The console view shows the MyEclipse direct output of any running server.

Server run output displayed in console view

In the console view, you can monitor the server (errors, records, and so on) and have your own server deployed to it. When your project is deployed on an application server, the application server runs in debug mode, and you can set breakpoints directly in the project source file, and then run the application so that the breakpoints are activated.

rad User Note : This debugging process IBM RAD users should be familiar with, this setting is similar to the basic mechanism of the breakpoint. For example, use a myblogstrutshibernateexample project from examples On-demand resources.

Example using breakpoints

Run the application at the top of the browser, in which case a new blog post will be posted. You can see that the postdaoclass below it is open. Also note that the text of the Postdao.save method is mentioned when the user clicks the Submit button to publish a Sina blog message. Suppose we want to debug this storage operation, you can do it by double-clicking on a breakpoint set in the left edge editor, and you can see that the breakpoint marker looks like a small ball. After clicking Submit in the browser, MyEclipse executes the breakpoint we set, then pauses execution of the application and opens the debug perspective to examine the state of any application and all runtimes we want to examine.

Pause debugging at a breakpoint

At the top of the screen you can see that we hit the breakpoint set, and you can see that we are checking the value of ransientinstance and whether its title and content values match the values entered into the table. These are a few examples of how debugging works in MyEclipse. You can set more breakpoints, conditional breakpoints, expressions, and so on, and you should know how to do it after looking at these examples.

7. Project Aspects

In MyEclipse, additional configuration information is added to provide more technical functionality to a given project (Java projects, Web projects, etc.), and libraries are used to provide the project with specialized tools to handle cooperation with new technologies. Not every feature can be added to a project, and some are used only for Web projects, while others are for any project. In addition, some facets cannot be added after some items have been added to the facets. In this case, those specific facets can be disabled from the project facets menu.

Available facets

When you add most facets, you are prompted to configure and install the feature for a given project that requires additional metadata. For example, adding javaserver faces or struts facets requires myeclipse to know where important files for a particular framework reside in your project, so it can provide them with additional tools.

Project configuration

When these facets are launched, you can take advantage of the specialized tools that MyEclipse provides for them, such as Visual Report Designer, Visual JSF page design (as shown), the Struts flow designer (as shown), and more professional tools for your business development.

Visual JSF Designer8. Other hotspot features
