Java + Flash Builder 4 + BlazeDS - Integração [resolvido]

JavaChild Membro desde: 15/06/2006 13:30:40 Mensagens: 121 Offline

Pessoal

Estou fazendo uma simples integração entre Java + Flash Builder 4 + BlazeDS, basicamente o flex vai exibir uma string vinda de uma classe java.

Eis a versão dos meus SWs:

eclipse-jee-ganymede-SR2-win32.zip
apache-tomcat-6.0.24.exe
blazeds-bin-3.2.0.3978.zip
flashbuilder4_b2_plugin_win_100509.exe
jdk-6u17-windows-i586.exe

Segue agora o passo a passo da montagem do meu sistema:

Inicialmente, eu crio um novo projeto Flex
-indico que é uma aplicação J2EE
-indico que usarei o BlazeDS
-seto nome da pasta que vai conter as classes Java

Indico que usarei o Tomcat, deixo o Output folder com o mesmo nome do Context folder -> WebContent

-Apago a pasta flex_libs e seto o Output Folder URL para: http://localhost:8080/p01/

meu projeto ficou assim:

Agora eu faço meu p01.mxml :

minha classe Java OlaMundo.java

No Web.xml faço a seguinte alteração:
eu alterei:

para:

no remoting-config.xml eu inclui a tag <destination> setando minha classe java:

Quando eu executo meu projeto (Run on Server) A minha tela aparece normal, mas quando eu insiro um texto no campo , aparece esse erro:

erro 1:

depois disso, eu tentei fazer 'qualquer alteração e rodar de novo, mas ai aparece esse erro:

Aparentemente, o meu Web.xml não está conseguindo linkar minha classe java com meu <s:RemoteObject id="locarSer" destination="servico"/> e o 2º erro RPC Fault faultString="Falha no envio" ... parece que está faltando alguma coisa ainda para fazer a classe se comunicar com o flex:

Alguem pode me dar uma luz do que pode estar faltando??

obrigado

eu apenas alterei o <welcome-file-list>.... o resto deixei como estava, será que o web.xml ainda está incompleto??

Vlws Fabio, mas mesmo fazendo essa correção, ainda dá esse erro:

o que mais pode estar errado?

eu Upei meu projeto p01.fxp no rapidshare, se alguem puder importar ele no FB4 pra bater o olho (ta leve) eu agradeço.

Fabião, perdoe a ignorancia....

percebi que na 2º linha: Status 404: url: 'http://localhost:8080/WebContent/messagebroker/amf'"

ele poe WebContent no lugar do nome do meu projeto p01

entao tentei fazer:

mas não deu certo tmbm!!

...mew q zica!!!

Deixa o services-config.xml como te passei.
E em Project > Properties dê uma olhada em Context Root de Flex Server e Web Project Settings. Os dois devem estar iguais, não sei pq no Flex Server normalmente fica /WebContent dando este erro.

Cara se não me engano você não configurou no seu compiler aonde está o arquivo eremoting.xml ... não lembro agora qual o argumento que tem q por lá mas isso é primordial pois é assim que o flex compila e sabe qual o nome dos services que irá se cominicar.
