Pessoal,

após ler o tutorial sobre o Axis aqui no GUJ, fiz a instalação do TomCat, Axis, criei meu primeiro WebService, mas tive problemas na hora de rodar o client.

Meu WebService possui a seguinte assinatura:

Este é o meu client:

import java.rmi.RemoteException;

import javax.xml.rpc.ServiceException;

import org.apache.axis.client.Call;
import org.apache.axis.client.Service;

public class ClientWS &#123;
    
    public static void main&#40;String&#91;&#93; args&#41; &#123;
    	
        try &#123;
			String endpoint = "http&#58;//localhost&#58;8080/axis/EASports.jws";
			Service service = new Service&#40;&#41;;
			Call call = &#40;Call&#41; service.createCall&#40;&#41;;
			call.setTargetEndpointAddress&#40;endpoint&#41;;
			call.setOperationName&#40;"testeWebService"&#41;;
			String ret = &#40;String&#41; call.invoke&#40;new Object&#91;&#93;&#123;new String&#40;"marco"&#41;&#125;&#41;;
			System.out.println&#40;"Got result &#58; " + ret&#41;;        	
        &#125; catch &#40;ServiceException se&#41; &#123;
        	System.out.println&#40;"ServiceException&#58; "+se.getMessage&#40;&#41;&#41;;
        &#125; catch &#40;RemoteException re&#41; &#123;
			System.out.println&#40;"RemoteException&#58; "+re.getMessage&#40;&#41;&#41;;
        &#125; catch &#40;Exception e&#41; &#123;
			System.out.println&#40;"Exception&#58; "+e.getMessage&#40;&#41;&#41;;
        &#125;
                
    &#125;
&#125;

E esta é a minha exception:

Alguém se habilita?

Você disse que leu o tutorial do axis agui no guj, onde está, não encontrei. Estou precisando invocar webservices feitos em delphi, vc sabe se é possível?

http://www.guj.com.br/servlet/guj?PARSE=true&MAMUTE_ACTION=br.com.guj.action.ListArticle&MAMUTE_TEMPLATE=ShowArticle&LIST_ARTICLE=single&ArticleId=32&PAGE=1

Acredito ser possível invocar WebServices feitos em qualquer linguagem, afinal, não é essa uma das vantagens do dito cujo?

espero que sim !!!

Pessoal,

descobri que meu problema estava na ordem do ClassPath. O Log4J estava sendo importado do pacote errado e por isso estava gerando aquela exception.

Infelizmente estou recebendo uma outra mensagem de erro quando rodo o meu Client:

A assinatura do WebService está correta:

public String testeWebService&#40;&#41;;

E se eu chamo a URL http://localhost:8080/axis/EASports.jws?wsdl, recebo a seguinte resposta:

Fui tentar compilar o arquivo FibClient do tutorial e obtive os seguintes erros:

--------------------Custom Tool: javac--------------------

FibClient.java:6: cannot resolve symbol

symbol  : class Service

location: class FibClient

Service service = new Service();

^

FibClient.java:6: cannot resolve symbol

symbol  : class Service

location: class FibClient

Service service = new Service();

FibClient.java:7: cannot resolve symbol

symbol  : class Call

location: class FibClient

Call call = (Call) service.createCall();

^

FibClient.java:7: cannot resolve symbol

symbol  : class Call

location: class FibClient

Call call = (Call) service.createCall();

^

4 errors

Process completed.

Já coloquei todos os .jar que tem dentro da instalação do axis no meu classpath. Você sabe o que pode estar faltando?

mcampelo 3 de mar. de 2004

Provavelmente está faltando os imports:

import org.apache.axis.client.Call;
import org.apache.axis.client.Service;

Exatamente…coloquei-os e funcionou !!! Valeu
E vc conseguiu resolver seu problema?

Infelizmente meu client ainda não está funcionando.

Você conseguiu rodar o exemplo completo? Seu client funcionou?

Entrei para a lista de usuários do Axis, postei uma mensagem lá, mas até agora fui ignorado solenemente, ou como gosta de dizer um amigo meu: defecaram no meu crânio!

consegui chamar o exemplo do Fibonacci mas o do Google não

mcampelo 3 de mar. de 2004

Então fiz alguma bobagem no meu Client, vou tentar de novo com um exemplo igual ao do artigo!

Quanto ao Google, você tem o número de licença para fazer a chamada ao WebService?

Realmente havia um erro no Client:

String ret = &#40;String&#41; call.invoke&#40;new Object&#91;&#93;&#123;new String&#40;&#41;&#125;&#41;;

Enquanto que a assinatura do meu WebService era:

Bastou alterar a assinatura do meu WebService e tudo funcionou:
