i'm trying to follow the exact same steps on this
Spring Boot Drools Rule Engine Example
but I have this error at compilation time :
Error creating bean with name 'kieContainer' defined in class path resource [.../DroolsConfig.class]: Failed to instantiate [org.kie.api.runtime.KieContainer]: Factory method 'kieContainer' threw exception with message: Cannot invoke "org.drools.compiler.compiler.Dialect.getBuilder(java.lang.Class)" because the return value of "org.drools.compiler.rule.builder.RuleBuildContext.getDialect()" is null ...................
those are the dependencies added to my pom.xml

I'm using spring boot 3
Thank you for your help!
I'm using java Records instead of normal class
I fixed it by adding this dependency to pom.xml

I want to access an oracle sql database using spring jpa since it's a remote server, and apache camel.
This is a code sample:
RouteBuilder
rest("/getfromdb")
.get()
.to("direct:getfromdb");
from("direct:getfromdb")
.transform().simple("SELECT PERSON_ID FROM XXISF_LEAVE_TEMP;")
.to("jdbc:dataSource") //spring boot starter jdbc creates the bean in the registry
.log("${body}");
application.properties file
server.port=9085
camel.servlet.mapping.context-path=/*
spring.datasource.url=jdbc:oracle:thin:#server:port/serviceName
spring.datasource.username=apps
spring.datasource.password=OneTeam2020
spring.jpa.hibernate.ddl-auto=update
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.format_sql=true
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.Oracle12cDialect
pom, dependencies related to jdbc and jpa:
<dependency>

Note that my oracle database is 19c, and I am getting the following errors:
1- java.sql.SQLException: Numeric Overflow
2- org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory;
3- nested exception is org.hibernate.exception.GenericJDBCException: Unable to build DatabaseInformation
So any idea how to solve this issue? because I did not find anything that could help. Thank you

I'm working on a webapp in Spring using Spring Tool Suite. If I build and deploy the application there using the IDE onto the provided Pivotal tc Server, it works just fine. However, if I do a manual "mvn clean package" build and attempt to deploy it to a standalone Tomcat server (using newest Tomcat 7), it throws the following exception:

What's the reason for this behavior and how can I solve this?
EDIT More information:
Adding <scope>provided</scope> to javax.servlet-api seems to fix the warning about javax.servlet-api not being loaded at the start. Problem with el-api still remains.
I've checked the tomcat/lib directory and it already contains el-api.jar in it, which is likely why it tells me it's not going to load the one I list in pom.xml. The thing is, adding <scope>provided</scope> doesn't fix it either. Whatever I do, it still complains gives me the same java.lang.NoClassDefFoundError: javax/el/ELManager error.
SOLUTION
In addition to the part in the edit above regarding javax.servlet-api the problem with el-api was that I was running a Tomcat 7 with provided el-api jar in version 2.2. The missing class was introduced in el-api 3.0. Running the same webapp in Tomcat 8 (with el-api 3.0 jar) works properly.
You miss the javax.el-api as dependency. Add:
<dependency>
<groupId>javax.el</groupId>
<artifactId>javax.el-api</artifactId>
<version>3.0.0</version>
</dependency>
to your pom.xml
Hibernate Validator 6.x -> Bean Validation 2.0 (JSR 380) -> EL3.0
Hibernate Validator 5.x -> Bean Validation 1.1 (JSR 349) -> EL2.2
Bean Validation 1.0 (JSR 303) -> (I'm not sure)
so,it also influence others version (tomcat,jdk,jsp,servlet)
such as tomcat7, if you want to use Hibernate Validator, should use Hibernate Validator 5.x, el 2.2 (and servlet 3.0, jsp 2.2 and jdk 6+)
Downgrade hibernate-validator to version 5 and it will work fine with Tomcat 7.
In my case I add next dependency to my pom:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>5.4.3.Final</version>
</dependency>
Or you can add newer el-api.jat to tomcat lib folder.
Please refer to Hibernate validation "Unable to initialize javax.el.ExpressionFactory" error
use
<dependency>
<groupId>org.glassfish</groupId>
<artifactId>javax.el</artifactId>
<version>3.0.1-b08</version>
</dependency>
I'm using Tomcat 7.0.9 and couldn't change to any newer one due my company bureaucracy. Importing EL as a dependency didn't solve it either.
At Tomcat's root folder -> lib I replaced old el-api (2.2 version of it) with a new 3.0 (from local .m2\repository\javax\el\javax.el-api\3.0.0). Then, isolating tomcat's dependencies correctly (as shown here) made my WAR be correctly deployed at Tomcat 7.0.9
Adding my answer for those having Tomcat 7 and trying to apply selected answer.
If adding dependency does not help you and you continue getting
java.lang.NoClassDefFoundError: javax/el/ELManager
that's because Tomcat 7 will not allow you to load a more modern jar with objects from javax.* package. It will print to the log:
jakarta.el-3.0.3.jar - jar not loaded. See Servlet Spec 3.0, section 10.7.2. Offending class: javax/el/Expression.class
The solution will be to either upgrade your Tomcat or downgrade hibernate-validator to the latest 5.x version. Another (less preferred from my POV) option would be to try to replace jars in your tomcat7/lib folder.
In my case,
Commented out this dependency,
<!-- <dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>6.0.8.Final</version>
</dependency> -->
and added
<dependency>
<groupId>javax.el</groupId>
<artifactId>javax.el-api</artifactId>
<version>3.0.0</version>
<scope>provided</scope>
</dependency>
This solved my issue
Try the following:
Add javax.eland javax.el-api to the pom.xml as others mention
If you have different classloaders - as often the case when using OSGi - you need to temporarily set the context to the one holding the implementation. Wrap your call with:
ClassLoader originalClassLoader = Thread.currentThread().getContextClassLoader();
try {
Class<?> currentClass = this.getClass(); // or any class that is in a bundle with the dependency
Thread.currentThread().setContextClassLoader(currentClass.getClassLoader());
// execute library call
} finally {
Thread.currentThread().setContextClassLoader(originalClassLoader); // back to original context
}
Add a service to META-INF/services/
Add a property to $java.home/lib/el.properties
Use the system property with the factoryId
When the library is instantiating the ExpressionFactory via > ELManager.newInstance(..) > FactoryFinder.find(..) it has several strategies to find an implementation. The call is hardcoded like this:
public static ExpressionFactory newInstance(Properties properties) {
return (ExpressionFactory) FactoryFinder.find(
"javax.el.ExpressionFactory", "com.sun.el.ExpressionFactoryImpl", properties);
}
See source of javax.el.FactoryFinder.find(..) for further information
I am trying to upgrade a project to use log4J2 instead of Log4J1. It is maven project which is using some other projects as well in its dependency. Before any dependency, I have following in POM file
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-api</artifactId>
<version>2.0-beta9</version>
</dependency>
<dependency>

</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-jcl</artifactId>
<version>2.0-beta9</version>
</dependency>
I have no compile time error, but when i try to execute, I keep getting following exception

You need to download jar containing org.apache.logging.log4j.LogManager and then set your classpath.
link to download log4j 2 jar
or try this
link to download jar
download required jar from these two link
