After "access.addItem(itemId, new DataCallback() {" nothing happen and no exception will be thrown

[Sascha Steiner]

Hi,

I am using "utgard" like it is discribed at "openscada.atlassian.net/wiki/display/OP/HowToStartWithUtgard" and it works perfect if i run it at my testscenario with an Matricon OPC server.

But if i try to run it by my customer everythink runs well till the "itemId" is added to the access object.

From this moment nothing else happen (no errorcode, no exception). I implemented an counter to see if the procedure is working but without any success.

I can reproduce this behavior if i write the wrong "itemId" in my testscenario but the "itemId's" should be ok couse i use the same like in the Matrikon Explorere.

Please have you any idea, i am working on this problem since days without any success. 

public void doConnect() {

try {

final ConnectionInformation ci = new ConnectionInformation();

ci.setHost(this.utut.txt_host.getText());

ci.setDomain(this.utut.txt_domain.getText());

ci.setUser(this.utut.txt_user.getText());

ci.setPassword(this.utut.txt_password.getText());

if(utut.chb_useId.isSelected()){

ci.setClsid(this.utut.txt_clsId.getText());

}else{

ci.setProgId(this.utut.txt_progId.getText());

}

final String itemId = this.utut.txt_itemId.getText();

// create a new server

final Server server = new Server(ci, Executors.newSingleThreadScheduledExecutor());

// connect to server

output.append("try to connect");

output.append("\n");

utut.txt_Output.setText(output.toString());

server.connect();

output.append("connected succesfully \n");

utut.txt_Output.setText(output.toString());

// add sync access, poll every 500 ms

AccessBase access;

access = new SyncAccess(server, 1000);

output.append("new access created \n");

utut.txt_Output.setText(output.toString());

output.append("new DataCallback will be created now \n");

utut.txt_Output.setText(output.toString());

access.addItem(itemId, new DataCallback() {

int counter = 0;

@Override

public void changed(Item item, ItemState state) {

output.append(state.toString());

output.append("\n");

output.append(String.valueOf(counter));

output.append("\n");

utut.txt_Output.setText(output.toString());

counter++;

}

});

// start reading

output.append("Start reading \n");

utut.txt_Output.setText(output.toString());

access.bind();

// wait a little bit

Thread.sleep(30 * 1000);

output.append("Stop reading \n");

utut.txt_Output.setText(output.toString());

//             stop reading

access.unbind();

output.append("Connection closed \n");

utut.txt_Output.setText(output.toString());

} catch ( Exception  e) {

//            System.out.println(String.format("%08X: %s", ((JIException) e).getErrorCode(), server.getErrorMessage(((JIException) e).getErrorCode())));

//         output.append(e.getMessage());

Writer writer = new StringWriter();

PrintWriter printWriter = new PrintWriter(writer);

e.printStackTrace(printWriter);

String s = writer.toString();

utut.txt_Error.setText(s);

}

thank's  a lot for any idea

greetings Sascha
