        Hi shiv

        Shiv:
        well.. i have that class "instanciacao" in the JBOSS Server like a "Web Service".. and i am invoking her from a client:

        Here is the code of the cliente..
        <% // includes necessários para ligar a um web service em AXIS %>
        <%@ page import="org.apache.axis.client.Call" %>
        <%@ page import="org.apache.axis.client.Service" %>
        <%@ page import="org.apache.axis.encoding.XMLType" %>
        <%@ page import="javax.xml.rpc.ParameterMode" %>
        <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">








        Introduza o nome do processo a ser instanciado:
        Introduza o valor da encomenda que deseja efectuar:







        <%


        if (!(request.getParameter("num1")==null))
        {
        if(!(request.getParameter("num1").equals("")))
        {
        String n1 = request.getParameter("num1");
        Integer n2 = new Integer(request.getParameter("num2"));

        String endpoint = "http://localhost:8080/axis/instanciacao.jws";

        //instânciar axis e call
        Service service = new Service();
        Call call = (Call) service.createCall();

        //url de ligação
        call.setTargetEndpointAddress( new java.net.URL(endpoint) );

        //nome do método a chamar
        call.setOperationName( "inst" );

        //definir nomes do parametros a enviar
        // configg=2;
        call.addParameter( "i", XMLType.XSD_INT, ParameterMode.IN );
        call.addParameter( "numero", XMLType.XSD_INT, ParameterMode.IN );




        //definir o tipo de retorno
        call.setReturnType(XMLType.XSD_ANYTYPE);

        //invocar o web service e imprimir o resultado na pagina
        call.invoke(new Object[]{n1,n2});
        // out.println("Resultado: "+ret);
        }
        }

        %>




        Shiv please take note that i am already changed the service.. so at this time the client choose the process name to instanciate and chage the value of one variable of that process..but you only have to change one or to thing to work with that class that i put here..if you have any more questions..please ask...
        I don´t make any changes to the configuration file... that service and this client(with a few changes) is enough to make the process start..

          Hi ronald!!

          Well regarding my error..

          I made many tests and it only apears that error when the process have tasks to be done by a user..like write the value of a variable..or something like this...

          When the task is to a user read a thing only.. and the process doesn´t have any more tasks, it finishs.. the error don´t appears...
          But on this final case i have to always shutdown the server and restart it.. to works..(is seems very strange)

          On one of your last posts you tell me to put here the logging regist of JBPM server..
          and think u are thinking on the : \jbpm-starters-kit-3.1\jbpm-server\server\jbpm\log right?

          where.. here ot comes.. i truly don´t understand this error..it can be because of some autentication process?.. because.. with the instantiation true java code..i am passing the process of "login" on the JBPM Web app.

            Thanks Ronald and Pedro,

            Your help is much appreciated.

            I am trying the code you have posted with default configuration using hibernate3.jar. And I am using the default configuration for HSQL database only. If I connect to the HSQL manager I could see the process definition "simple":

            select * from jbpm_processdefinition;

            However I get the following error "table not found" sql exception when I execute the code: This suggests that the jbpm_processdefinition table is not in the query. Am I missing something. If it is a trivial issue, please post any pointers that help me progress.

              It looks like the sql statement has jbpm_processdefinition, but the error message says table not found in the statement. does it refer that the table is not found in the database?
