Hi
I saw and have installed WTP. I am a novice in this, but i want to try my hand in flex as i have some spare time now. Can you tell me how to create a simple java/flex project using only WTP.
Say, for populating a string in a textinput area from a javaclass.
Can you send me or even upload a complete zip folder, so that I can get the directory structure and what goes in which folder and also how the class and mxml will get connect.. Please Someone help me. I have eclipse and flex 3 builder

Mihai,

I am also running Flash Builder 4 Beta 2 on Mac. I want to do combined Flex/Java development. I am supposed to install the Eclipse WTP plug-in to be able to do that. I went through the process you illustrated above for i.e. Help -> Software updates -> Find and install -> Select new features to install. i arrived at 2 options:

1. Ganymede Discovery
2. The Eclipse Project Updates

Ganymede Discovery gives this error message:- “NAB/MWT for Linux GTK (0.9.9.200806181757) operating system does not match current environment.”

The Eclipse Project Updates opens another field with several features under it but does not include WTP plug-in.

i followed the link you provided to Eclipse.org site. Clicked on downloads and this is where I got even more confused. Nothing there made any sense because It was hard to determine one is which. Please help. Thanx in advance.

Hi Santosh,

Europa is the older version auf eclipse 3.3

Ganymede is the name of version 3.4

see
http://en.wikipedia.org/wiki/Eclipse_ide

So take ganymede and it should work!

Mihai,

Great article but I am not able do this for Flash Builder 4 Beta 2. I don’t see Europa Discovery and see Ganymede Discovery instead. I couldn’t get far in the wizard as it kept telling me of incompatible configuration.

Help please!

Thanks for helping me get the project setup with WTP. Can you shed some light on how to deploy a war file with everything packaged correctly via Eclipse? Is there a way to automate this process? When I do Export/ Select War
/WAR Export/ Destination = tomcat/webapps/flex_project I get the following error:
java.lang.NoClassDefFoundError: Could not initialize class org.eclipse.jst.j2ee.commonarchivecore.internal.CommonArchiveFactoryRegistry

I guess I’m missing something in the initial server setup; I’m not clear on how and when the project, or which parts of it, are to be deployed.
I’m using Adobe Flex Builder 3 on top of
Eclipse Version: 3.4.2

Thanks!

Hi,

Thanks for posting this nice tutorial but i have a question. I am trying to develop a flex application with java/j2ee. I was wondering how to communicate from one flex page to other using servlet as controller.
I am trying to develop a small application like login,registration and search from database using Flex as front end and Java/J2ee as back end.

I hope you would have got an idea i am trying to develop.
Please help me in this regard.

Thanks,
Rakesh

@Henmang

If the class stays on the server, then yes. There are two server side frameworks from Adobe (BlazeDS -open source and LiveCycle Data Services -commercial product) that offer RMI style invocation of the exposed classes on the server from the Flex/AIR client. If you search on remoting Flex and Java you’ll find tones of articles explaining this topic

Hi,

Is it possible to directly invoke a java class from flex application?

Thanks.

Thanks a lot for you very informative post. It helped me to set up my Flex/Java project with LiveCycle in 15 minutes.

Keep up the good work!

@toswf

I think you made a mistake, because normally the URL should look like this: http://localhost:8400/WTP_test/WTP_test.html

By: toswf

toswf — Fri, 04 Sep 2009 07:47:55 +0000

hello!
we have finished as you said in the article,but we can not run on server.It simply said can not find the resource.the url is http://localhost:8400/WTP_test/WEB-INF/classes/WTP_test.mxml/

@Christian

The simplest solution, I think, is to use Data Messaging. Your Flex client is the consumer, and the java classes are the producer.

Java classes are not compiled and transformed into ActionScript code.

Christian — Fri, 21 Aug 2009 15:11:18 +0000

Hello folks, well i am a little confused about the use of Flex and java, this is my problem: My java application must read two .zip files from an online server. These classes will load and parse the data in a Thread and perform certain actions depending on such info. The problem occurs when my flex application calls the java method that queries such data. I need to WAIT until the loading has finished. Any ideas?
Another doubt is if the Java classes are being compiled and transformed into some form of ActionScript classes.
Maybe I’m lost in space, so please I need a light in the darkness, thank you.

@Anil

Hi there, you should find the executable inside the Flex Builder installation folder. If you have the standalone version of Flex Builder, it might be named “FlexBuilder.exe”.

Hi,
I am very new to Flex Builder and need to create J2EE project. I have already added WTP in Flex Builder 3, but still don’t see “Create combined Java/Flex project using WTP” coming for me. How can I run eclipse.exe with -clean as I don’t find “eclipse.exe” inside Adobe ?

Thanks,
Anil

Hello,

Can somebody suggest how to add JBoss server to the target runtime?

I am getting this error:
Missing classpath entry \your_server_root\appservers\jboss\bin\run.jar

Please suggest!

Hello

Thanks for give idea about configure flex and java project.But one important things is how The Add/remove project option is enable.This happened add webproject capability in your project.Then only you can deploy your project in server.(right click your project-> My eclipse->Add web service capability)

Thanks,
Mejat

@Meysam

After you select “Web and JEE Development” and press “Select required” you will have automatically selected all the required plug-ins (do not uncheck anything!), all you have to do is to press the Next button.
