the first type: Javaproject and Flexproject IndependentSuch a way is also very many people use the way. The Flex program Ape and Java program Ape work independently of each other. The following are described below: First, the need for software Myeclipes + Tomcat6.0 + Flex Builder3 + blazeds, online to download themselves. Second, configure the server side (Myeclipes + Tomcat6.0 + blazeds) 1, first unpack the BlazeDS compression package, in the Find Blazeds.war decompression open, get Meta-inf directory and Web-inf directory. 2. Open Myeclipes, configure Tomcat server: Window->preferences->myeclipes->application server->tomcat->tomcat 6. X Configure Tomcat home directory for the installation path for Tomcat, and select Tomcat server->enable at the same time. 3. Next, create a Web project,project name peace in MyEclipse. 4, then the first step decompression Blazeds.war obtained two directories pasted into the Webroot directory under the Peace project, the Override Prompt box appears, select Yes to all. 5, the following in the SRC folder of this project to write a Java class (package name Com.nankyrei.service, class name HelloWorld): Packages Com.nankyrei.servicepublic Class Helloworld{public String Gethello () {return "Hello world"; }}6, Java class is written, the following to declare this class in Remoting-config.xml (Bold part): &LT;?MXL version= "1.0" encoding= "UTF-8"? ><service id= " Remoting-service "class=" Flex.messaging.services.RemotingService "><adapters><adapter-definition id=" Java-object "class=" Flex.messaging.services.remoting.adapters.JavaAdapter "default=" true "/></adapters>
<default-channels><channel ref= "MY-AMF"/></default-channels><destination id= "HelloWorld" ><porperties><!--here to write the full path: Package name + class name--><source>com.nankyrei.service.helloworld</source> </porperties></destination></service>7, okay, done, now deploy this project to Tomcatzhong and start Tomcat. Third, create a flexclient1, a new Flex project, named Flex_peace, select Application Server TYPE:J2EE. 2. This step is important, click Next, set server location, where root folder is the peace project path that was just deployed in Tomcat. To maintain consistency, the name of the relative path in the root URL and the context root remains the same as the Web project name. When these three items are filled in, you need to click on the "Validate Configuration" button for configuration verification (this is where Tomcat is turned on). Click Finish when the verification is complete. 3.

1. Switch to Flex view to create a new flex project, such as

The project is designed to mix Java EE projects with FLEXLCDS projects.

Of course if you do not choose combined Two together, then the trouble: either you create a separate

2. Click Next to configure J2eeserver, for example, to

The runtime of Tomcat simply requires the installation folder of Tomcat to be specified.

The Content folder is actually the container folder that was finally compiled, so BlazeDS's Blazeds.war
The file will be published to the Flex folder under Web-inf in this folder. At the same time because the tutorial is used
MyEclipse, his default is to publish the contents of the WebRoot, in order to self-initiative, so this change to
WebRoot (This is also the custom of Java development)

The Flex WAR file refers to the path of the Flex.war files after the LCDs is installed, but here we use
is blazeds to replace LCDs, so here is the path of Blazeds.war.

Compilation options Specifies how the Flex file is compiled, selecting the recommended Flexbuilder
Although the development time is more time, but after the publication will not occupy the server's compilation processing time,
There are advantages for the user.

Output folder refers to the path where the Flex-compiled SWF and HTML files are stored, changed to
WebRoot, meaning that it can be published to the root folder. Of course, you can set your own according to your needs and habits.

5. After project is built, you can make many other settings by right-click Properties.

6, such a Flex+java project is established.
7, the preparation of samples, testing in the introduction of the third way after the unified introduction.

Third: by Web project Reverse adding Flex, which is Java+flex

2. Manually add the required elements of flex to Flexweb project.
1) First copy the jar files required by BlazeDS to the Lib folder of project. To be able to build that flex
The jar file under Project Lib is copied under the Lib folder under Project.
2) then add the required configuration file for Flex blazeds. Create a new text named Flex under Web-inf
folder, and then copy the four XML files that we created above the Firstflex to the file
Clamp down.
3) Finally, change the Web. xml file to increase the Flex configuration. Procedure a simple put up above us new
Part of the code for the Flexproject Web. XML is copied over.

3. Publish the project to Tomcat and start Tomcat. (Note: Be sure to start Tomcat because in the back
setting, it verifies the path to project)
4. Then right-click on the project? Flex Project Nature? ADD Flex Project Nature

5, set up, you will find that the folder structure of WebProject has changed, for example.
We find that the folder structure of project created in this form is slightly different from the other method, and the Flex

6, assume that you are not very comfortable with this folder structure, but also want to put the flex files in the Flex_src folder, don't worry,
We can set it by right-click property. For example with

Here you can set up your Flex source folder and output folder again
7. Configure the Flex Default SDK. After this configuration, not yet, the program may not be able to perform properly, but also need to

8, immediately finished, let us write a program to test it.
1) Create a new Java class: Hello.java
Package com;

public class Hello {
public string Hello (string name) {
SYSTEM.OUT.PRINTLN ("Flex calls me, it's good ~ ~ ~");
Return "Hello" +name;
}
}
2) Configure the object to be called for Flex, change Web-inf/flex under Remoting-config.xml
Increase:
<destination id= "Hello" >
<properties>
<source>
Com. Hello
</source>
</properties>
</destination>

3) Write a flex program
<?xml version= "1.0" encoding= "Utf-8"?>
<mx:application xmlns:mx= "Http://www.adobe.com/2006/mxml"
layout= "Absolute" >
<mx:Script>
<! [cdata[
Import mx.rpc.events.ResultEvent;

function Gg (evnet:resultevent): void{
var ff:string = Evnet.result as String;
Ggg.text = FF;
}

function Remotingsayhello (): void{
var sname:string = Nameinput.text;
H.hello (sname);
}
]]>
</mx:Script>

<mx:remoteobject destination= "Hello" id= "H"
result= "GG (event)"
Endpoint= "HTTP://LOCALHOST:8080/FLEXWEB/MESSAGEBROKER/AMF" >

</mx:RemoteObject>


<mx:textarea id= "GGG" x= "109" y= "122"/>

<mx:button label= "Say hello" click= "Remotingsayhello ();"
x= "144" y= "193"/>
<mx:textinput id= "Nameinput" x= 109 "y="/>
<mx:label text= "name" x= "y="/>
</mx:Application>
4) Restart Tomcat to execute flexweb.mxml.
The third method, after compiling, access to the page will appear 404 exceptions. Detailed reasons are unknown. But it will still compile the

Now the interface:

Configuration success, Happy, O (∩_∩) o ... Ha ha.
If you use LCDs, you do not need to precompile, you can directly access the Mxml file, LCDs will dynamically compile the returned results.

Solve:

Countdown No. One Line of 404 exception, and I found a third leak against the other and the third kind.

This directory, so solve the method: The missing directory from another copy of the entire project, refresh, must be refreshed to appear

This directory has these contents, the talent is successful.
