(Note: Due to lack of answers I also posted the same question to the Liferay forum)
I am trying to create a file entry in Liferay 7:
DLAppServiceUtil.addFileEntry(
34613, // groupId
0, // folderId
"hello.txt",
"text/plain",
"title",
"description",
"changeLog",
new File("hello.txt"),
new ServiceContext()
);
Result:
com.liferay.portal.kernel.security.auth.PrincipalException: Principal is null

The exception is thrown by this part of Liferay's source code:
public long getUserId() throws PrincipalException {
String name = PrincipalThreadLocal.getName();
if (Validator.isNull(name)) {
throw new PrincipalException("Principal is null");
}
Should I try to perform a PrincipalThreadLocal.setName before calling that method? That sounds risky, so I am sure there is a better way? (actually I tried, that leads to a further PrincipalException: PermissionChecker not initialized)

I have a Spring Batch app that is reading couple of million records from an Azure SQL db (P11), does some calls, then updates those records. Below is the configuration of that particular step.
The 'chunksize' is 400 and the 'throttleLimit' is 30
#Bean
public Step coreCardProcessStep(JpaPagingItemReader<CoreCardEntity> sqlCoreLoadItemReader,
StepBuilderFactory stepBuilderFactory,
OutCoreCardProcessor outCoreCardProcessor,
CoreProcessStepCardWriter coreProcessStepCardWriter
) {
log.info("coreCardProcessingStep: creating a step for processing sql rows");
return stepBuilderFactory.get("CORE_CARD_PROCESSOR STEP 001")
.<CoreCardEntity, CoreCardEntity>chunk(chunkSize)
.reader(sqlCoreLoadItemReader)
.processor(outCoreCardProcessor)
.writer(coreProcessStepCardWriter)
.taskExecutor(new SimpleAsyncTaskExecutor("coreCardLoad"))
.throttleLimit(throttleLimit)
.build();
}
My writer is actually a JPA writer but implemented ourselves
#Slf4j
#Component
#RequiredArgsConstructor
public class CoreProcessStepCardWriter implements ItemWriter<CoreCardEntity> {
private final CoreCardRepository coreCardRepository;
#Override
public void write(List<? extends CoreCardEntity> coreCards) throws Exception {
log.info("write: number of cards: {}", coreCards.size());
coreCardRepository.saveAll(coreCards);
}
}
The problem is that after already processed a few 10000 records correctly I somehow get an IllegalThreadStateException which as far as I know can only happen if something tries to start a Thread that is already started. The exception is thrown from the writer just when it tries to saveAll and it happens on all concurrent chunks. This is the stacktrace of the actual underlying problem (Spring Batch itself is wrapping all exceptions from each chunk up in something else after the failure):

I don't quite understand how this happens, let alone how to fix it. Anyone has any idea?
When you use a multi-threaded step, the batch artifacts (reader, writer, etc) should be thread-safe. Please refer to the documentation here: Multi-threaded Step. In your case, you should synchronize your item writer or make it step-scoped.
Another option is to use a partitioned step (instead of a multi-threaded step), where each partition is a distinct data set that is processed by a distinct worker thread.
As a side note, I'd recommend using a ThreadPoolTaskExecutor, because the SimpleAsyncTaskExecutor does not re-use threads.
I'm using Junit 5 and mockito for some unit testing.
method call to be mocked is as follows. It returns a Mono and takes in two String arguments.
Mono<Void> doSomething(String id, String user);
I'm mocking it as follows
#MockBeam MyServiceClass service;
when(service.doSomething(eq(ID), eq(USER_ID)).thenReturn(Mono.empty());
This results a null pointers as follows
java.lang.NullPointerException

I am able to read the text of an element on a web page through my cucumber steps file but when I want to move that method to Page Object file then system throws an error.
The framework used: Groovy, Geb, Cucumber, Gradle
Steps file
com.checkout.automation.buy.stepdefs
import com.buyautomation.pages.CartPage
import com.buyautomation.pages.common.CookieTrait
import com.checkout.automation.services.Util
import com.expectedData.CartPageExpectedData

import cucumber.api.java.en.Then
import cucumber.api.java.en.When
class CartSteps extends GebCuke implements CookieTrait {

CartSteps(Util util) {
this.util = util
}
#Then("I am notified that my cart is empty")
def emptyCartNotificationCheck() {
if (CIASteps.user == "Guest User") {
at CartPage
// This does not work
assert getEmptyCartText()== CartPageExpectedData.expectedText.emptyCartGuestUserHeading + CartPageExpectedData.expectedText.emptyCartGuestUserSubText
//This works
assert $("div.empty-cart__info").text() == CartPageExpectedData.expectedText.emptyCartGuestUserHeading + CartPageExpectedData.expectedText.emptyCartGuestUserSubText
}
else {
assert $("div.empty-cart__info").text() == CartPageExpectedData.expectedText.emptyCartRegisteredUserHeading + CartPageExpectedData.expectedText.emptyCartRegisteredUserText
}
}
}
Page Object File. I want to store the element locator and functions which deal with elements in this file
package com.buyautomation.pages
import geb.Page
class CartPage extends Page {
static at = { assert title == "Cart" }
static content = {
emptyCart(wait:true) {$("div", class:"empty-cart__info")}
itemQuantity(wait:true) {$("div", class:"cart-item__quantity-block")}
}
def getEmptyCartText() {
emptyCart.text()
}
Error: When using method to get the text using page object function then I get the below error. However , If I refer to element directly in the step file then the code works

Try prefix the method call with the page object class CartPage:
assert CartPage.getEmptyCartText()== CartPageExpectedData.expectedText.emptyCartGuestUserHeading + CartPageExpectedData.expectedText.emptyCartGuestUserSubText
Although your error is stating that it can't find itemQuantity which is being called in your When step:
When I update the quantity to exceed the maximum limit(cartMessages.feature:33)
Make sure you use CartPage.itemQuantity when referencing it.
And import the CartPage within your test:
import com.buyautomation.pages.CartPage
Related to this question, I got the tip that the getOrCreate idiom should be used to avoid this issues. But trying:
JavaStreamingContextFactory contextFactory = new JavaStreamingContextFactory() {
#Override
public JavaStreamingContext create() {
final SparkConf conf = new SparkConf().setAppName(NAME);
return new JavaStreamingContext(conf, Durations.seconds(BATCH_SPAN));
}
};
final JavaStreamingContext context = JavaStreamingContext.getOrCreate("/tmp/"+NAME, contextFactory);
I'm still getting:

What am I suppose of being doing wrong?
Thanks in advance.
According to this question I think this is how I should do it:
SparkConf conf = new SparkConf().setAppName(NAME);
JavaSparkContext ctx = JavaSparkContext.fromSparkContext(SparkContext.getOrCreate(conf));
JavaStreamingContext context = new JavaStreamingContext(ctx, Durations.seconds(BATCH_SPAN));
Right?
Ok, this is my first time using Javafx and Scene Builder but I've run into a problem I can't find a solution for.
Basically, I'm making an app which includes a settings tab in which the user can change the colour theme of the app (i.e a light theme with light coloured background, buttons, tabs, textfields, etc) using radioButtons. So if the user clicks on the "light" radioButton, it should load the "light" css file, if "dark" radioButton is selected, it should change to use the "dark" css file, etc.
In the controller class I have the following:
#FXML
RadioButton rbtnLight;
#FXML
public void colourThemeLight(javafx.event.ActionEvent event)
{
if (rbtnLight.isSelected() == true)
{
System.out.println("I'm the chosen button");
//I'm using println at the moment to test that it's actually recognizing the action performed
}
}
#FXML
RadioButton rbtnDark;
#FXML
public void colourThemeDark(javafx.event.ActionEvent event)
{
if (rbtnDark.isSelected() == true)
{
System.out.println("I'm the other chosen button");
//Again, I'm using println at the moment to test that it's actually recognizing the action performed
}
}
But it gives a 'RuntimeException: java.lang.reflect.InvocationTargetException'
caused by a NullPointerException at the if (rbtnLight.isSelected() = true) and the if (rbtnLight.isSelected() = true statements.
I've also tried using the rbtnLight.isDisabled() == false and .isPressed() == true however both give the same error.
Alternatively, I've tried if (event.getSource() == rbtnTLightS) but that does nothing, literally. No errors, but no message either.
In Scene Builder, I have loaded the style sheets to the main windows, not the individual radioButtons in the settings tab.
(Almost done...)
If and when that does get working, how would I get the right css file loaded? I have one method I've found which is the following:
File file = new File("path");
String css1 = file.toString();
mainS.getStyleClass().add(css1); //mainS being the main screen in sceneBuilder which everything is placed on
But I'm skeptical whether or not that would work.
Any and all help would be much appreciated. Sorry for the essay :)

Would the method I posted about loading a different css file work?
No.
mainS.getStyleClass().add(css1);
will not work, since getStyleClass() accepts the CSS selectors defined in CSS style sheet file, and not its path or name.
It should be
mainS.getStyleSheets().add(css1);
See this example of changing css at runtime.
