Myeclipse+weblogic+oracle+plsql Configuration Considerations

WebLogic configuration details: "WebLogic Installation and Configuration Diagram"
Oracle+plsql configuration details: "PL/SQL access to remote Oracle Server (multiple Ways)"
MyEclipse configuration: "Eclipse in the development of Web project configuration Optimization", "teach you to crack myeclipse to 2016," the text of the "
Although summarized above development environment configuration and optimization, but in the use of the process still appear more or less, large and small problems, unified record.
1.MyEclipse Import Project.
File-->import-->general, which has two options: Existing Projects into Workspace, File System. The difference is that the file system imports a filesystem, moves the folder to workspace, changes the project's path, and Existing projects is importing an existing project without changing anything.
The reason for referring to a path is that when I deploy a Web project with WebLogic, if using the file system causes WebLogic to be not the same as the project MyEclipse, you must use existing Projects into Workspace.
The two are understood as a stack principle in the JVM. WebLogic and MyEclipse are like declarative variables in the stack, and Web projects are like objects that open up space in a heap. The File system is an object with two declarations pointing to two different addresses, and Existing projects is two declarations pointing to an object.
2.PLSQL "Ora-12154:tns: Unable to resolve the specified connection identifier" at logon.
This is one of the most common mistakes, and there are various online answers. Follow the second article at the beginning of the article carefully check that the Oracle+plsql no problem, only the last one, but also the most easily overlooked reason: Plsql the installation path appears in parentheses.

"--a vital warning message, which I didn't take seriously, led me to troubleshoot the problem all day. It turns out that my system is 64bitwindows7,32bit. The default installation path for programs is generally "program Files (x86)", which is the result of this abominable (x86). Know the reason, uninstall, reinstall, modify the path, solve the problem.
