hamcrest | Hamcrest is a library of matchers , which can be | Regex library

I'm looking at an XPath query in the project's code base:

count(//*[local-name() = 'Offer'])

I need to modify the code so that it checks for a count of 7. I don't know what that would look like. Is it this?

[count(//*[local-name() = 'Offer']) = 7]

PS: I'm using Java and RestAssured to run a test. Looks like I have the option of using a Hamcrest matcher or an XmlAssert matcher.

I have an application using Boot Strap running with cassandra 4.0, Cassandra java drive 4.11.1, spark 3.1.1 into ubuntu 20.4 with jdk 8_292 and python 3.6.

When I run a function that it call CQL by spark, the tomcat gave me the error bellow.

Stack trace:

I'm having some issues upgrading from SpringBoot 2.4.5 to 2.5.0. The project is a Kotlin project, which also uses Keycloak with version 13.0.0 as IDM.

The error happens on startup of the app and on tests. The exception is thrown within ConfigServletWebServerApplicationContext with the message Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'springSecurityFilterChain' defined in class path resource [org/springframework/security/config/annotation/web/configuration/WebSecurityConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.servlet.Filter]: Factory method 'springSecurityFilterChain' threw exception; nested exception is java.lang.NullPointerException

You can also checkout the SecurityConfig.kt, SecurityConfigTest.kt and both stacktraces (normal startup of the app and test) in the following:

I am puzzled to solve this com.fasterxml.jackson.dataformat.xml.XmlMapper error with Java 11. I want to use XmlMapper only from jackson dependency and that's why excluded from springboot starter web , still cannot figure how to resolve it's dependency. providing as much details as possible -

build.gradle

We have an existing application which is working fine with the SpringBoot 2.2.2.RELEASE. Now we tried to upgrade it to the SpringBoot 2.4.2 version and application is not getting started and throws the following error. In the classpath I could see only one spring-webmvc-5.3.2.jar file.

Below is the pom.xml for the referance:

:( Application Error
If you are the application administrator, you can access the diagnostic resources.

Of course, I checked azure logs and that's what I've observed:

I'm trying to port the Espresso sample from Java to Kotlin, I got an error for the WebView version

I'm using the name MainActivity.kt as is, it just simple and works well:

I built the Apache Oozie 5.2.1 from the source code in my MacOS and currently having trouble running it. The ClassNotFoundException indicates a missing class org.apache.hadoop.conf.Configuration but it is available in both libext/ and the Hadoop file system.

I followed the 1st approach given here to copy Hadoop libraries to Oozie binary distro. https://oozie.apache.org/docs/5.2.1/DG_QuickStart.html

I downloaded Hadoop 2.6.0 distro and copied all the jars to libext before running Oozie in addition to other configs, etc as specified in the following blog.

https://www.trytechstuff.com/how-to-setup-apache-hadoop-2-6-0-version-single-node-on-ubuntu-mac/

This is how I installed Hadoop in MacOS. Hadoop 2.6.0 is working fine. http://zhongyaonan.com/hadoop-tutorial/setting-up-hadoop-2-6-on-mac-osx-yosemite.html

This looks pretty basic issue but could not find why the jar/class in libext is not loaded.

• OS: MacOS 10.14.6 (Mojave)
• JAVA: 1.8.0_191
• Hadoop: 2.6.0 (running in the Mac)

I'm using Azure to host my Java Spring Boot application. I have created a trial to test this solution and I managed to deploy my application following this tutorial Deploy with Azure which is using the azure-webapp-maven-plugin and the command mvn azure-webapp:deploy.

My problem is that when I'm making changes inside my application and I want to apply them in my Azure Web App but nothing actually update when I reach the page, here is the message after using the deploy command :
