Developing the first web program with Eclipse MyECLIPSE WebLogic8.1
1. Installing JRE Eclipse Although it is developed by Java, it is not brought by JRE. So you must install yourself, go http://java.sun.com/downloads to download the latest J2SE1.4.2_03 JRE installation file J2RE-1_4_2_03-Windows-i586-P.exe. After the installation is successful, restart the machine and add the JRE's BIN folder path to the system environment variable path, such as: C: / Program Files / Java / J2RE1.4.2_03 / bin. 2. Install Eclipse2.1.2 Eclipse The latest Stable is already build to 3.0m5, but this version of LanguagePackFeature has not been launched, there is a problem with LanguagePackFeaRe2.1.2. Therefore, it is recommended to use Eclipse to stabilize version 2.1.2, and the full Chinese interface can be implemented after LanguagePackFeature 2.1.2. Eclipse SDK 2.1.2 and its LanguagePackFeaature download address is http://download2.eclipse.org/downloads. Eclipse installation is very simple, just unpacking Eclipse-sdk-2.1.2-win32.zip, copy the folder Eclipse to the place you want. Then double-click Eclipse.exe to start compiling and initialize Eclipse, and automatically enter Eclipse. Let's start installing LanguagePackFeature. (1) Unzip Eclipse2.1.2.1-sdk-win32-languagePackFeature.zip.

Press the Finish button to close the dialog box. A "LanguagePack" appears in the Feature Updates view. To expand this item, you can see a lot of language pack plugins. (4) Select a language package, such as: Eclipse Java Development Tool Language Pack 1.2.1.2, click the Install Now button in the right view to start installing. After the installation is successful, Eclipse will restart. Install all the language package plugins according to the subkey. You will find all interfaces into Simplified Chinese throughout the installation process. 3.

The path of the folder where Eclipse is located during the installation process, and the Eclipse will be automatically entered after the installation is successful. At this time, you will find more "myeclipse" in the main menu, and we choose the Window / Preferences menu to open the preference dialog.

Simultaneous configurations are as follows: (1) BEA Home Directory: D: / BEA. Assume that WebLogic is installed in the D: / BEA folder. (2) WebLogic Installation Directory: D: / bea / weblogic81. (3) Admin UserName: User. (4) admin Password: 12345678. (5) Execution Domain root: D: / bea / user_projects / dev. (6) Execution Domain Name: DEV. (7) Execution Server name: admin. (8) Hostname: PortNumber: Localhost: 7001. (9) Security Policy File: D: /bea/weblogic81/server/lib/weblogic.policy. (10) Jaas login configuration file: omitted.

Here we use the SQL Server database drive library D: /bea/weblogic81/server/lib/msqlogic81/server/lib/mssqlserver4v65.jar with WebLogic SQL Server Database. At this point, the configuration of WebLogic8 in myECLIPSE is completed. Let's take a look at whether you can start WebLogic in Eclipse?
