I have two servlets in my project: - The login servlet tooks the username and the password, checks if user data is correct and eventually returns the name of the related database; - The debug servlet for now can only output a string. In MainEntryPoint I call the login servlet before the debug servlet, but I get an output that indicates that the debug servlet is called before the login servlet; this is the code snippet:
logInService.logIn(userNameTextBox.getText(), passWordTextBox.getText(), new AsyncCallback<String>() { @Override public void onFailure(Throwable caught) { Window.alert("Log in failed!"); } @Override public void onSuccess(String result) { dataBaseString = result; } }); deBugService.outPut("2) DataBase: " + dataBaseString, new AsyncCallback<Void>() { public void onFailure(Throwable caught) { } public void onSuccess(Void result) { } }); And this is the related output: 2) DataBase: null 1) DataBase: dataBaseName Look at my first post to see the other code snippets On Aug 4, 3:47 pm, Apocalypto <lmelon...@gmail.com> wrote: > Thanks for the reply, I included "validation-api-1.0.0.GA.jar" and > "validation-api-1.0.0.GA-sources.jar" to project libraries and the > errors were solved.
