I am trying to use JxBrowser in Eclipse plugin by following https://jxbrowser.support.teamdev.com/support/solutions/articles/9000013072-using-jxbrowser-in-swt.
Here's part of my code:
import org.eclipse.swt.SWT;
import org.eclipse.swt.awt.SWT_AWT;
import com.teamdev.jxbrowser.chromium.swing.BrowserView;
import com.teamdev.jxbrowser.chromium.Browser;
#Override
public void init() {
Runtime.getRuntime().addShutdownHook(new Thread() {
#Override
public void run() {
// TODO Auto-generated method stub
if (Environment.isMac()) {
BrowserCore.shutdown();
}
}
});
}
#Override
public void createPartControl(Composite parent) {
// TODO Auto-generated method stub
Browser browser = new Browser();
BrowserView view = new BrowserView(browser);
Composite composite = new Composite(parent,
SWT.EMBEDDED | SWT.NO_BACKGROUND);
Frame frame = SWT_AWT.new_Frame(composite);
frame.add(view);
browser.loadURL("http://html5test.com");
}
It works well on Windows and Ubuntu.
But I got exception on Mac:
com.teamdev.jxbrowser.chromium.internal.ipc.IPCException: Failed to initialize IPC. Remote process doesn't respond.

I did some searching and got a simlar question here: JxBrowser doesn't start, but it didn't work for me. Seems nothing about BrowserCore.initialize() since it's in SWT model.

I try to write tests with EasyMock and because I want to mock a static method I want to use PowerMock. When I want to run the test I get a ClassNotFoundException.
This is the test I wrote:
#Test
public void whenCreate_ThenCurrentAccountShouldBeFound() throws Exception {
Account oldAccount = new Account();
oldAccount.setUsername("Test");
oldAccount.setFirstName("FirstName");
oldAccount.setLastName("LastName");
oldAccount.setPassword("Password");
oldAccount.setEmail("maxmusteg#hs-pforzheim.de");
PowerMock.mockStatic(AuthenticationService.class);
PowerMock.expectNew(de.hspf.nxtgenmondial.backend.service.AuthenticationService.getCurrentlyLoggedInUser()).andReturn(oldAccount);
replayAll();
assertEquals("Username name should be Test", "Test", accountService.getCurrentAccount().getUsername());
}
This is the static method:
public static String getCurrentlyLoggedInUser() {
if (SecurityContextHolder.getContext().getAuthentication() != null && SecurityContextHolder.getContext().getAuthentication().getPrincipal() != null) {
if (SecurityContextHolder.getContext().getAuthentication().getPrincipal() instanceof ExtendedUserDetails)
return ((ExtendedUserDetails) SecurityContextHolder.getContext().getAuthentication().getPrincipal()).getUsername();
else
return ((UserDetails) SecurityContextHolder.getContext().getAuthentication().getPrincipal()).getUsername();
} else
throw new IllegalStateException("No user logged in");
}
And then there is the getCurrentAccount method:
public Account getCurrentAccount() {
Optional<Account> optionalAccount = accountRepository.findOneByEmail(AuthenticationService.getCurrentlyLoggedInUser());
if (optionalAccount.isPresent())
return optionalAccount.get();
else {
log.warn("Logged in account not found in database");
return null;
}
}
This is the error message that appears. Line 105 is where PowerMock.mockStatic() is called:

You are using a version of PowerMock that isn't compatible with your version of EasyMock. From what I see, it is PowerMock that is too old.
here is my setup below,
#SpringBootApplication
#ComponentScan(basePackages = "com.amazonaws.serverless.sample.springboot.controller")
public class Application extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
public class LambdaHandler implements RequestStreamHandler {
private SpringBootLambdaContainerHandler<AwsProxyRequest, AwsProxyResponse> handler;
private static ObjectMapper mapper = new ObjectMapper();
private Logger log = LoggerFactory.getLogger(LambdaHandler.class);
#Override
public void handleRequest(InputStream inputStream, OutputStream outputStream, Context context)
throws IOException {
if (handler == null) {
try {
handler = SpringBootLambdaContainerHandler.getAwsProxyHandler(Application.class);
} catch (ContainerInitializationException e) {
e.printStackTrace();
outputStream.close();
return;
}
}
AwsProxyRequest request = mapper.readValue(inputStream, AwsProxyRequest.class);
AwsProxyResponse resp = handler.proxy(request, context);
mapper.writeValue(outputStream, resp);
// just in case it wasn't closed by the mapper
outputStream.close();
}
}
each time when when I am trying invoke my lambda from local console using command - "serverless invoke local -f hello" I am getting below exception,

Please HELP me resolve this, I tried various ways of boot setup with aws lambda but failed every time. Please help me fix this or help me out in setting up in any other way. Thanks.
In your logs we can see :
NoClassDefFoundError: javax/servlet/ServletContainerInitializer
ClassNotFoundException: javax.servlet.ServletContainerInitializer
Could you please check if libs are loaded , there must be something missing and not loaded up correctly
Also, something like this has been done
<dependency>
<groupId>com.amazonaws.serverless</groupId>
<artifactId>aws-serverless-java-container-spring</artifactId>
<version>1.3.2</version>
</dependency>
Also double check steps in :
https://github.com/awslabs/aws-serverless-java-container/wiki/Quick-start---Spring-Boot
I had the same issue. I was using version 0.2 of aws-serverless-java-container-spring and had to switch to version 1.3.2 as the former version didn't have SpringBootLambdaContainerHandler class.
When cloning this project https://github.com/artem-zinnatullin/droidcon-nyc-2017-puzzlers.git
The project failed to build and I got an error.
It seems like the problem in rxjava lib but i cannot find out.

I would like to get the id of the currently logged in user and use it to access their specific user page.
To implement that I have been able to get the current logged in user's name using:
#RequestMapping(value = "/main/home", method = RequestMethod.GET)
public String getHomePage(Model model, Principal principal, HttpServletRequest
request) {
try {
CustomUser customUser =
(CustomUser)SecurityContextHolder.getContext()
.getAuthentication().getPrincipal();
request.getSession().setAttribute("name",
customUser.getName());
request.getSession().setAttribute("userId",
customUser.getUserId());
request.getSession().setAttribute("user", customUser);
} catch (Exception e) {
e.printStackTrace();
}
return "/main/home";
}
Then in the JSP page, I'm using the following code to try to get the user's page based on their id:
<c:url value="/main/user/?userId=${user.userId}" var="url"/><a href="<c:out
value='${url}'/>">User Page</a>
But this implementation is not working. When I click on the user page, I receive the following error:
java.lang.IllegalArgumentException: id to load is required for loading

I would like any insight into knowing why I cannot request the user's id but I can get the user's name.
I am trying to run a very simple ActiveMQ client script in GroovyConsole. I've included activemq-all-5.5.0.jar and slf4j-api-1.5.11.jar through the Script > Add Jar to ClassPath menu. I see org.apache.activemq.ActiveMQPrefetchPolicy in the activemq jar, yet I am getting the exception below.
Here is the script:
import org.apache.activemq.*
import org.apache.activemq.command.*
import javax.jms.*
//
//
//
def connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:61616")
def connection =connectionFactory.createConnection()
def session = connection.createSession(false,Session.AUTO_ACKNOWLEDGE)
def dest = new ActiveMQQueue("fieldrepresentative.updatelatlong.queue")
def producer = session.createProducer(dest)
connection.start()
def MapMessage message = session.createMapMessage()
message.setString("employeeId", "TS12345")
message.setString("latitude", "12345")
message.setString("longitude", "97874")
producer.send(message)
session.close()
connection.close()
The exception is:

I think you also need to have added to your classpath:-
lib/optional/slf4j-log4j12-1.5.11.jar
lib/optional/log4j-1.2.14.jar
I think because of this pre slf4j 1.6.0 'feature':- http://www.slf4j.org/manual.html#libraries
