I am using vaadin7 with grails i have created model and service and trying to access it when click on login button to check login details.
I search a lot but no relevant result, i am new to grails framework.
i am getting below error when trying to access service class:-

My Vaadincode is below :-
class Test extends UI {
public Test() {
// TODO Auto-generated constructor stub
}
#Override
protected void init(VaadinRequest request) {
HorizontalLayout fields = new HorizontalLayout();
fields.setSpacing(true);
fields.setMargin(true);
fields.addStyleName("fields");
final TextField username = new TextField("Username");
username.focus();
fields.addComponent(username);
final PasswordField password = new PasswordField("Password");
fields.addComponent(password);
final Button signin = new Button("Sign In");
signin.addStyleName("default");
fields.addComponent(signin);
fields.setComponentAlignment(signin, Alignment.BOTTOM_LEFT);
final ShortcutListener enter = new ShortcutListener("Sign In",
KeyCode.ENTER, null) {
#Override
public void handleAction(Object sender, Object target) {
signin.click();
}
};
signin.addClickListener(new ClickListener() {
#Override
public void buttonClick(ClickEvent event) {
if (username.getValue() != null
&& username.getValue().equals("")
&& password.getValue() != null
&& password.getValue().equals("")) {
signin.removeShortcutListener(enter);
PeopleService p1 = new PeopleService();
p1.checkLogin("", "");
// iPeopleService.checkLogin(username.getValue(), password.getValue());
buildMainView();
} else {
}
}
});
signin.addShortcutListener(enter);
setContent(fields);
}
}
And domain class :-
class People {
String name;
String apppassword;
static constraints = {
}
}
and Grails services code :-
#Transactional
class PeopleService {
def serviceMethod() {
}
public People checkLogin(String username, String password) {
def query = People.where{
peopleID == username &&
apppassword == password &&
visible == true
}
return people = query.find()
}
i below is the datasource :-
development {
dataSource {
driverClassName = "com.mysql.jdbc.Driver"
url = "jdbc:mysql://localhost/sample"
username = "root"
password = "root"
loggingSql = true
}
}
i did not understand the reason of this error. Can someone please help me?
Thanks

I've encountered this problem while trying to use cellData -> cellData.getValue() to add an attribute from an object, the attribute is a StringProperty and i have a method to return it, and i'm using it in the cellData -> cellData.getValue().methodtoreturnproperty, but it's still giving me java.lang.reflect.InvocationTargetException, does anyone know what i'm doing wrong?
Here's the code:

There's a class called Sala, that's being imported into this controller, i could make it work with another class called Filmes, i don't know exactly why it's not working with the class Sala, here's the code in the class:
package projeto;

import javafx.beans.property.StringProperty;
public class Sala {
private boolean e3d;
private int assentosMax;
private int assentosDisp;
private final StringProperty numeroProperty = new SimpleStringProperty();
public Sala(boolean e3d, int assentosMax, int assentosDisp, String numero) {
setNumero(numero);
e3d = this.e3d;
assentosMax = this.assentosMax;
assentosDisp = this.assentosDisp;
}
public boolean isE3d() {
return e3d;
}
public void setE3d(boolean e3d) {
this.e3d = e3d;
}

}

}
public int getAssentosDisp() {

}
public void setAssentosDisp(int assentosDisp) {

}
public StringProperty numeroProperty() {
return numeroProperty;
}
public final String getNumero() {
return numeroProperty.get();
}
public final void setNumero(String numero) {
numeroProperty().set(numero);
}
}
Edit: Here's the error:

Thanks in advance!
This looks like you are expecting one type of object in the table but providing another.
You define your table like this:
#FXML
private TableColumn<Filmes, String> salaColumn;
Your cell value factory is trying to get the following:
salaColumn.setCellValueFactory(cellData -> cellData.getValue().numeroProperty());
The numeroProperty is on the Sala object, not the Filmes Object.
Try the following (Though I am not 100% sure, since your definition of Filmes is not in the question):
salaColumn.setCellValueFactory(cellData -> cellData.getValue().getSala().numeroProperty());
Also - if there is a chance that the Sala object could be null, you'll want to check for that before trying to access the numeroProperty().
I am trying to send a file to Remote SFTP server. I have created a factory and an outboundFlow for the same.

Now i want to test the outbound flow using an integration test. For that i have created below testContext:
TestContextConfiguration
#Configuration
public class TestContextConfiguration {
#Configuration
#Import({ FakeSftpServer.class, JmxAutoConfiguration.class, IntegrationAutoConfiguration.class,
UploaderSftpConnectionFactoryBuilder.class })
#IntegrationComponentScan
public static class ContextConfiguration {
#Value("${report-uploader.reportingServer.fileEncoding}")
private String fileEncoding;
#Autowired
private FakeSftpServer fakeSftpServer;
#Autowired
#Qualifier("cachedSftpSessionFactory")
//CachingSessionFactory<LsEntry> cachedSftpSessionFactory;
DefaultSftpSessionFactory cachedSftpSessionFactory;
#Bean
public IntegrationFlow sftpOutboundFlow() {
return IntegrationFlows
.from("toSftpChannel")
.handle(Sftp.outboundAdapter(this.cachedSftpSessionFactory, FileExistsMode.REPLACE)
.charset(Charset.forName(fileEncoding)).remoteFileSeparator("\\")
.remoteDirectory(this.fakeSftpServer.getTargetSftpDirectory().getPath())
.fileNameExpression("payload.getName()").autoCreateDirectory(true)
.useTemporaryFileName(true).temporaryFileSuffix(".tranferring")
).get();
}
#Bean
public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
return new PropertySourcesPlaceholderConfigurer();
}
}
I have also created a fake sftp server as suggested # https://github.com/spring-projects/spring-integration-java-dsl/blob/master/src/test/java/org/springframework/integration/dsl/test/sftp/TestSftpServer.java
Below is my fake server:
FakeSftpServer
#Configuration("fakeSftpServer")
public class FakeSftpServer implements InitializingBean, DisposableBean {
private final SshServer server = SshServer.setUpDefaultServer();
private final int port = SocketUtils.findAvailableTcpPort();
private final TemporaryFolder sftpFolder;
private final TemporaryFolder localFolder;
private volatile File sftpRootFolder;
private volatile File sourceSftpDirectory;
private volatile File targetSftpDirectory;
private volatile File sourceLocalDirectory;
private volatile File targetLocalDirectory;
public FakeSftpServer() {
this.sftpFolder = new TemporaryFolder() {
#Override
public void create() throws IOException {
super.create();
sftpRootFolder = this.newFolder("sftpTest");
targetSftpDirectory = new File(sftpRootFolder, "sftpTarget");
targetSftpDirectory.mkdir();
}
};
this.localFolder = new TemporaryFolder() {
#Override
public void create() throws IOException {
super.create();
File rootFolder = this.newFolder("sftpTest");
sourceLocalDirectory = new File(rootFolder, "localSource");
sourceLocalDirectory.mkdirs();
File file = new File(sourceLocalDirectory, "localSource1.txt");
file.createNewFile();
file = new File(sourceLocalDirectory, "localSource2.txt");
file.createNewFile();
File subSourceLocalDirectory = new File(sourceLocalDirectory, "subLocalSource");
subSourceLocalDirectory.mkdir();
file = new File(subSourceLocalDirectory, "subLocalSource1.txt");
file.createNewFile();
}
};
}
#Override
public void afterPropertiesSet() throws Exception {
this.sftpFolder.create();
this.localFolder.create();
this.server.setPasswordAuthenticator((username, password, session) -> true);
this.server.setPort(this.port);
this.server.setKeyPairProvider(new SimpleGeneratorHostKeyProvider(new File("src/test/resources/hostkey.ser")));
this.server.setSubsystemFactories(Arrays.<NamedFactory<Command>>asList(new SftpSubsystemFactory()));
this.server.setFileSystemFactory(new VirtualFileSystemFactory(sftpRootFolder.toPath()));
this.server.start();
}
#Override
public void destroy() throws Exception {
this.server.stop();
this.sftpFolder.delete();
this.localFolder.delete();
}
public File getSourceLocalDirectory() {
return this.sourceLocalDirectory;
}
public File getTargetLocalDirectory() {
return this.targetLocalDirectory;
}
public String getTargetLocalDirectoryName() {
return this.targetLocalDirectory.getAbsolutePath() + File.separator;
}
public File getTargetSftpDirectory() {
return this.targetSftpDirectory;
}
public void recursiveDelete(File file) {
File[] files = file.listFiles();
if (files != null) {
for (File each : files) {
recursiveDelete(each);
}
}
if (!(file.equals(this.targetSftpDirectory) || file.equals(this.targetLocalDirectory))) {
file.delete();
}
}
}
Finally below is my test class
TestConnectionFactory
#ContextConfiguration(classes = { TestContextConfiguration.class }, initializers = {ConfigFileApplicationContextInitializer.class})
#RunWith(SpringJUnit4ClassRunner.class)
#DirtiesContext
public class TestConnectionFactory {
#Autowired
#Qualifier("cachedSftpSessionFactory")
CachingSessionFactory<LsEntry> cachedSftpSessionFactory;
//DefaultSftpSessionFactory cachedSftpSessionFactory;
#Autowired
FakeSftpServer fakeSftpServer;
#Autowired
#Qualifier("toSftpChannel")
private MessageChannel toSftpChannel;
#After
public void setupRemoteFileServers() {
this.fakeSftpServer.recursiveDelete(this.fakeSftpServer.getSourceLocalDirectory());
this.fakeSftpServer.recursiveDelete(this.fakeSftpServer.getTargetSftpDirectory());
}
#Test
public void testSftpOutboundFlow() {
boolean status = this.toSftpChannel.send(MessageBuilder.withPayload(new File(this.fakeSftpServer.getSourceLocalDirectory() + "\\" + "localSource1.txt")).build());
RemoteFileTemplate<ChannelSftp.LsEntry> template = new RemoteFileTemplate<>(this.cachedSftpSessionFactory);
ChannelSftp.LsEntry[] files = template.execute(session ->
session.list(this.fakeSftpServer.getTargetSftpDirectory() + "\\" + "localSource1.txt"));
assertEquals(1, files.length);
//assertEquals(3, files[0].getAttrs().getSize());
}
}
Now when i am running this test, I am getting the below exception:

which i am not able to resolve it and stuck on it for quite a time now. I am a beginner with spring-integration-dsl and any help woul be really appreciated.
Caused by: java.net.ConnectException: Connection refused: connect
You are connecting to the wrong port.
The test connection factory listens on a random port - you need to use the same port.
I am creating a RCP application. I have a view class NewView.
public class NewView extends ViewPart {
private DataBindingContext m_bindingContext;
public static final String ID = "com.app.Editor.newView";
SaveNewFileBean bean = new SaveNewFileBean();
private StyledText text;
public NewView() {
}
#Override
public void createPartControl(Composite parent) {
text = new StyledText(parent, SWT.BORDER);
m_bindingContext = initDataBindings();
}
public String returnText(){
String textData = bean.getText();
return textData;
}
#Override
public void setFocus() {
}
protected DataBindingContext initDataBindings() {
DataBindingContext bindingContext = new DataBindingContext();
//
IObservableValue observeTextTextObserveWidget = WidgetProperties.text(SWT.Modify).observe(text);
IObservableValue textBeanObserveValue = PojoProperties.value("text").observe(bean);
bindingContext.bindValue(observeTextTextObserveWidget, textBeanObserveValue, null, null);
//
return bindingContext;
}
}
When I am running the application first time, I click on New Menu and everything everything is working fine. But, When I am trying to load it again by clicking on New again, it doesn't give any error. But, it doesn't load the perspective also.
Is there some issue with my code?
Thanks!
edit: New is command. New calls a handler NewFileHandler which in turn calls NewView.java using the below code.
public class NewFileHandler extends AbstractHandler {
#Override
public Object execute(ExecutionEvent event) throws ExecutionException {
SwitchPerspectiveAction action = new SwitchPerspectiveAction();
action.run(NewFilePerspective.ID);
return null;
}
}
SwitchPerspectiveASction Class
public class SwitchPerspectiveAction extends Action {
public void run(String newPerspectiveID) {
if (PlatformUI.getWorkbench() != null) {
try {
PlatformUI.getWorkbench().showPerspective(newPerspectiveID,
PlatformUI.getWorkbench().getActiveWorkbenchWindow());
} catch (WorkbenchException e) {
e.printStackTrace();
}
}
}
}
edit:
I tried with this code.
IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
try {
page.showView(OpenFilePerspective.ID, "1" , IWorkbenchPage.VIEW_ACTIVATE);
} catch (PartInitException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
GIves error.

showPerspective doesn't do anything if the perspective is already open. You can't use this to open multiple copies of the same view.
If you just want to open a view use:
IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
IViewPart viewPart = page.showView("the view id");
Note that this will only show one instance of the view at a time.
To close a view use:
page.hideView(viewPart);
You can show multiple copies of a view by using a secondary id for the view:
page.showView("view id", "secondary id", IWorkbenchPage.VIEW_ACTIVATE);
The secondary id does not have to be defined anywhere. It just needs to be unique for each view you want to show.

KINDLY PROVIDE ME WITH THE FIX...TY
...And there you have it: Service implementation URL not specified...
You need to somehow tell GWT where on the backend the RPC call should go. You may do that with the annotation #RemoteServiceRelativePath on the service interface or programmatically on the ServiceDefTarget instance (which is effectively your async service instance).
Cheers,
