然后一步步的下一步。到了列表选择项目的时候。
从列表中选择
应用服务器（IIS,ASP.NET）

   然后确定，下一步
frontpage server extension和asp.net

如果要支持.Net，都打勾，前者vs用到。

然后一路下一步。成功后最后mmc管理去。

设置篇：

1：支持Asp：
控制面板 -> 管理工具 ->IIS(Internet 服务器)- Web服务扩展 -> Active Server Pages -> 允许

控制面板 -> 管理工具 ->IIS(Internet 服务器)- Web服务扩展 -> 在服务端的包含文件 -> 允许

2：上传200K限制：

先在服务里关闭iis admin service服务
找到windows\system32\inesrv\下的metabase.xml,
打开，找到ASPMaxRequestEntityAllowed 把他修改为需要的值，
然后iisreset

3：启用父路径：

IIS-网站－主目录－配置－选项－启用父路

Introduction

The Eclipse Platform features a Java debugger that provides all standard debugging functionality, including the ability to perform step execution, setting of breakpoints and values, inspecting variables and values, and to suspend and resume threads. With the extension MyEclipse you are able to debug JSP and included files too.

The debug perspective

First we will explain the debug perspective. You can activate the perspective under Windows > Open Perspective > Other...

Alternatively, you can click on the debug icon of the perspective tool bar.

Debug view

The Debug view displays the stack trace for the suspended threads for each target you are debugging. Each entry is the variable state of a method right when it called the next method. The view allows you to manage the debugging of a program in the workbench.

Variables view

The view displays information about the variables in the selected class. You can get information about the variable like value, size and more from this view.

Breakpoints view

The view lists all breakpoints you have set in the workbench project. In this view, you can enable or disable breakpoints, remove them, or add a new ones. You can also double-click a breakpoint to display its location in the editor.

This view also lists Java exception breakpoints, which suspend execution at the point where the exception is thrown. You can add or remove exceptions.

Expressions view

You can inspect data from each class of a suspended thread, and other places in this view. It opens automatically when an item is added to the view.

Debug a web project

In the next steps I will explain how you can debug a project. I will refer to the project JSP + Servlet you can download on our site. http://www.laliluna.de/assets/tutorials/java-servlets-jsp-tutorial.zip

Open the class BookEdit.java and set a breakpoint in the method doGet(..) at line 72. You can set a breakpoint by double-click on the info bar on the left edge of the editor, or right click Toggle Breakpoint.

Set the second breakpoint in the bookEdit.jsp file on the HTML start tag at line 14.

Note: If you don't have installed MyEclipse, you can't set a breakpoint in jsp and included files.

To see all breakpoints you can use the Breakpoints view in the debug perspective.

Breakpoint Properties

You can apply some properties to each breakpoint, for example how many times a breakpoint can hit before it suspends the thread or on which condition it suspends the thread.

Select the breakpoint right mouse button and choose the option Breakpoint Properties.

Hit Count

The hit count sets a number of times the breakpoint can be executed before the thread suspends. Very helpful in a loop expression or if you want to know the value of a expression after some hits.

Enable Condition

There are two options to suspend a thread by using a condition.

• if the enabled condition is true

• if the enabled condition changes

If you want that the condition suspends the thread when it is true select the option condition is true on Suspend when.

Example:

action.equals("edit");

If you want that the condition suspends the thread when the value of the condition changes select the option value of the condition changes on Suspend when.

Suspend Policy

You can define if the breakpoint suspends only the thread or the complete virtual machine.

Deploy and Debug

Now we want to debug the project, so deploy it and call it in your web browser.
Choose Edit on the list of books.

After you clicked the Edit link, eclipse shows you the following confirm window. You can choose if you want to switch to the debug perspective. Yes, you want it ;- )

The first entry in the debug view represents the state of the method where the breakpoint was set. You can preview the state of a entry simply by clicking on it, also the file will be open where the method is placed.

You can see the values of all variables of the selected entry in the Variables view.

A marked line and an arrow at the breakpoint shows that the debugger is suspended on this line.

If you've decided that you missed an important place in the execution process, perhaps the breakpoint was in the wrong place, or maybe you accidentally stepped over some code you wanted to inspect earlier in the process. Eclipse has a feature called Drop to frame, that essentially lets you 'rewind' the execution to the beginning of any method in the stack. This is especially useful when you perform variable modification or code hot swapping.
Right click on the frame and choose the option Drop to Frame.

Inspect expressions

To get informations about expression, you can inspect a expression. Right click on the marked expression, you want to inspect and choose Inspect or press Ctrl + Shift + I. A pop-up window appears that holds the informations about the expression.

Watch expressions

Watch is similar to inspect an expression. Watch means that the expression will be added to the Expressions view, where you can watch the informations about the expression. Add two expressions to the Expressions view.

Mark the expressions, right click and choose Watch.

Now the two expression are in the Expressions view.

Display expressions

If you want to display the type and the value of an expression, mark the expression and choose the Display option from the context menu (right mouse button) or press Ctrl + Shift + D.

Run to Line

If you set a breakpoint and somewhere under the breakpoint is a line you want to go, you can use the option Run to Line. The code between the breakpoint and the selected line will be executed. Select the line you want to go, press the right mouse button and choose the option Run to Line or use the key binding Ctrl + R.

Debugging JSP files (supported by MyEclipse)

Debugging a JSP file is the same like debugging a Java class, but the most features (Watch, Inspect, etc) are not implemented. The only way to get the values of variables is the Variables view.

That's it. You will only need to debug, when you make mistakes. Avoid them and forget the tutorial.
