WebService Java + Servidor JBoss + Client Delphi 7
Estou fazendo testes em WebService no JBoss e estou com um problema ao acessar o webservice pelo Delphi.
Criei dois metodos no WebService, o primeiro não recebe parametro nenhum so devolve um valor string. O Segundo recebe um parametro String e devolve uma string concatenada.
No segundo estou tendo problema na passagem de parâmetro do delphi para o webservice. O seviço esta recebendo null no parametro.
Alguem sabe o que pode estar ocorrendo ?
Segue o codigo do webservice e o codigo de acesso do delphi:
No codigo abaixo a funçao gravar com parametro esta recebendo sempre null no parametro de envio.
//codigo webservice
package com.sistemabancario.servico;
import javax.ejb.;
import javax.jws.;
@Stateless
@WebService
public class GerenteWS implements GerenteWSRemote {
public String gravarSemParametro() {
//
System.out.println("WebService executado no servidor.");
//
return "ParametroDeRetorno";
}
@Override
public String gravarComParametro(String envio) {
// TODO Auto-generated method stub
return envio + " adicionei mais texto no retorno";
}
}
