xls format`I am developing a spring boot restful service which need to use the Business Rule Management System. I have chosen the drools. Chosen the latest version.
I am using spring boot 2.7.7 version, drools version 8.33.0.Final & java 17 version.
Issue: I am not able to process the rules when I add in the .xlsx or .xls or .csv format.
I have tried with different options, but not working with .xlsx or .xls or .csv format. Any suggestion is welcome.
Warning error message in console:
No files found for KieBase defaultKieBase

I am using vlcj-4.7.1 and IntelliJ.
I am using the code from https://www.tutorialspoint.com/vlcj/vlcj_play.htm
The code runs and plays the video when I run it inside the IDE, but when I run it using Windows Terminal, I receive:
Error: Unable to initialize main class alan.bartlett.videotester.App
Caused by: java.lang.NoClassDefFoundError: uk/co/caprica/vlcj/player/component/EmbeddedMediaPlayerComponent
Any ideas how to fix this ClassNotFoundError? I have installed VLC 3.0.17.4 if that info is useful.

I'm not sure what I'm doing wrong.
Resolved it.
Just found that my file in META-INF file was name for ThemeSelectorProviderFactory instead of UserStorageProviderFactory.
I am new to spring data gemfire/apache geode. I am getting the following error. Can anyone explain what is wrong with my configuration?

Spring Data GemFire is tightly coupled with log4j2.
I've fixed the classcast exception with the following configuration:
pom.xml
Exclude the spring-boot-starter-logging from spring-boot-starter
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-logging</artifactId>
</exclusion>
</exclusions>
</dependency>
(Optional) Add a log4j2.xml file under the src/maini/resources/folder
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN" monitorInterval="30">
<Properties>
<Property name="LOG_PATTERN">

</Appenders>
<Loggers>
<Root level="info">

</Root>
</Loggers>
</Configuration>
Placing one (and only one) of slf4j-nop.jar slf4j-simple.jar, slf4j-log4j12.jar, slf4j-jdk14.jar or logback-classic.jar dependendcy
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
</dependency>
i had the similar issue with
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'gemfireCache' defined in .....
java.lang.ClassCastException: org.apache.logging.slf4j.SLF4JLogger cannot be cast to org.apache.logging.log4j.core.Logger at ..
i had this dependency in my build gradle
compile 'org.springframework.data:spring-data-geode:2.0.10.RELEASE'
Fixed issue after adding this ->
configurations.all {
exclude group: 'org.apache.logging.log4j', module: 'log4j-to-slf4j'
}
When I run test using grizzly2 follow steps here . Everything works fine. Then I tried jersey-test-framework-provider-jetty, exception happend:
MessageBodyReader not found for media type=text/html;charset=iso-8859-1, type=class com.example.resource.GenericPair, genericType=com.example.resource.GenericPair<java.lang.Integer, java.lang.String>.

Response is:

May be It need some more configure using jetty. Here is my configure
#Override
protected Application configure() {
return new ResourceConfig(TestApi.class)
.register(JacksonFeature.class)
.register(JacksonJsonProvider.class)
.packages("com.example.api");
}
