Struggling sending e-mails with log4j2 and SMTP Appender

I'm completely new to springboot and log4j2, and I cannot manage to send e-mail for a certain type of log (Warn&Error). I dont' understand why i get "ERROR Unable to invoke factory method in class org.apache.logging.log4j.core.appender.SmtpAppender" message. Does anyone have a clue?

I've tried plenty of things, but cannot mannage du make it work. Does anyone avec a clue?

Your are facing one of the side-effects of the gap between Java EE 8 and Jakarta EE 9 (it's a very disruptive renaming of classes): Spring Boot 3.x contains an implementation of Jakarta Mail 2.0, while the SMTP appender in Log4j2 Core requires and implementation of Java Mail 1.6.
To fill the gap, we published an alternative implementation of MailManager (the engine behind the SMTP appender) in the log4j-jakarta-smtp artifact. To use it, you just need to add it to your runtime classpath:
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-jakarta-smtp</artifactId>
<scope>runtime</scope>
<exclusions>
<exclusion>
<groupId>com.sun.activation</groupId>
<artifactId>jakarta-activation</artifactId>
</exclusion>
<exclusion>
<groupId>com.sun.mail</groupId>
<artifactId>smtp</artifactId>
</exclusion>
</exclusions>
</dependency>
(the version is managed by Spring Boot).

Try replacing
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
with the following the dependencies
<dependency>
<groupId>com.sun.mail</groupId>
<artifactId>javax.mail</artifactId>
<version>1.6.2</version>
</dependency>
<dependency>
<groupId>javax.activation</groupId>
<artifactId>javax.activation-api</artifactId>
<version>1.2.0</version>
<scope>runtime</scope>
</dependency>

multi-pom in intellijIDEA. Error adding module to project: null

I wanted to make a multi-pom project in Intellij (2020.3.4). In one Maven project, I right-click ->New -> Module -> Maven. select parent to "my project". However, even if parent is not specified, I get the error: Error adding module to project: null. (at the same time, it adds a regular folder with the module name and an empty pom.xml inside) (This happens with any archetype). I didn't find any solutions on the Internet at all. Only downgrade to the old version of Intellij IDEA and that solution was published 10 years ago. Tell me what is the problem? Or what to do? Does not work only with "Maven". With "Java" and "Spring Inizializr" it works.

I reinstalled windows. (I needed it anyway) and installed intellij IDEA 2021.3 instead of 2020.3. Everything worked. Some of this has affected. Perhaps reinstalling the same version would also solve this problem.

In Intellij goto File -> Project Structure -> Project SDK -> [Select Your Installed SDK Version] -> Ok
And try to add the new module, it worked for me.

Titan loading problems with elastic search

I'm using the following code to load Titan:
TitanFactory.Builder config = TitanFactory.build();
config.set("storage.backend", "berkeleyje");
config.set("storage.directory", DIRECTORY);
//config.set("storage.conf-file", "file:////" + DIRECTORY + "/cassandra/cassandra.yaml");
config.set("index." + INDEX_NAME + ".backend", "elasticsearch");
config.set("index." + INDEX_NAME + ".DIRECTORY", DIRECTORY + File.separator + "es");
config.set("index." + INDEX_NAME + ".elasticsearch.local-mode", true);
config.set("index." + INDEX_NAME + ".elasticsearch.client-only", false);
graph = config.open();
loading dependencies with gradle:
compile group: 'com.thinkaurelius.titan', name: 'titan-all', version: '1.0.0'
My project directory is:
/home/ray/IdeaProjects/BAG - Byzantine fault-tolerant Architecture for Graph database/
my titan is in this project directory in the folder "TITAN"
That's what I set in the Directory variable.
Still on start it always crashes:

You should be more specific on your Titan dependencies so you don't pull in unintended artifacts. Instead of using titan-all, try something like this:
compile group: 'com.thinkaurelius.titan', name: 'titan-berkeleyje', version: '1.0.0'
compile group: 'com.thinkaurelius.titan', name: 'titan-es', version: '1.0.0'
You should not need to include gremlin-core explicitly because it is a dependency of titan-core, however if you do add it, it should be aligned with the TinkerPop version that Titan 1.0 uses:
compile group: 'org.apache.tinkerpop', name: 'gremlin-core', version: '3.0.1-incubating'
Updated
Your previous failed attempts have likely created an invalid graph instance stored under DIRECTORY. You must recursively remove DIRECTORY before attempting to create a new graph using the same directory.
Elasticsearch indexing backend does not work with a index.search.DIRECTORY configuration (note the case). This is the relevant part of the stack trace:
Ignored configuration entry for index.search.DIRECTORY since it does not map to an option
java.lang.IllegalArgumentException: Unknown configuration element in namespace [root.index]: DIRECTORY
You can read more about the various Elasticsearch configuration options in Chapter 22 of the Titan documentation.
Instead of Elasticsearch, consider using Lucene. Its configuration looks similar to BerkeleyJE storage, and both are well-suited for a single-machine Titan.
TitanFactory.Builder config = TitanFactory.build();
config.set("storage.backend", "berkeleyje");
config.set("storage.directory", DIRECTORY + File.separator + "berkeleyje");
config.set("index." + INDEX_NAME + ".backend", "lucene");
config.set("index." + INDEX_NAME + ".directory", DIRECTORY + File.separator + "lucene");
graph = config.open();
Also update build.gradle with the dependency for lucene:
compile group: 'com.thinkaurelius.titan', name: 'titan-berkeleyje', version: '1.0.0'
compile group: 'com.thinkaurelius.titan', name: 'titan-lucene', version: '1.0.0'
I'd also recommend trying to build a Titan project without Neo4j, OrientDB, Sparksee, and other non-Titan dependencies first to ensure you have a simple project that works without any dependency conflicts.

You appear to have a classpath issue:
Caused by: java.lang.NoSuchFieldError: LUCENE_3_6 at org.elasticsearch.Version.(Version.java:43)
Titan-es 1.0.0 depends on Elasticsearch 1.5.1 which again depends on Lucene 4.10.4 which has a deprecated field org.apache.lucene.util.Version.LUCENE_3_6. This field was removed in later versions of Lucene. You need to check your classpath and make sure you are pulling in the correct version of Lucene.

Is there a dependency I am missing out or this some other problem? Please suggest possible things I can try for solving this problem. If you know a better solution to write logs in Logstash Json format you may suggest.

I suspect you are missing one of the Jackson dependencies.
You have jackson-core-asl, I think you need these three:
com.fasterxml.jackson.core:jackson-core:jar:2.6.3
com.fasterxml.jackson.core:jackson-databind:jar:2.6.3
com.fasterxml.jackson.core:jackson-annotations:jar:2.6.0
The ultimate source of truth for dependencies is the dependency tree of the Log4j 2 implementation module.
You may be able to get more details on the problem by setting <Configuration status="debug" ... in your configuration.

log4j2 LoggerContext not showing up in JMX Gui or JConsole

My Google foo is letting me down today! I am trying to configure log4j2 so that I can access the loggers via JMX and change their log levels.
However, when I hook everything up, none of the loggers show up in the JMX tree (or log4j-jmx-gui) as shown in the log4j2 JMX docs. Only the log4j2 ContextSelector and StatusLogger in the JConsole attribute tree and the StatusLogger tab in the log4j-jmx-gui (stand-alone or as a plugin) show up. No LoggerContext elements.
I've googled and not come up with anything! That probably means I'm missing something somewhere. Any help would be greatly appreciated by me and wall which I'm banging my head against :)
I'm using Log4j2 beta9 with Java 1.6.0_45-b06 on win7. I have tried it on Java 7 and it results in the same behaviour.
The log4j2 dependencies being used:
log4j-api-2.0-beta9.jar
log4j-core-2.0-beta9.jar
My log4j2.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<Configuration status="debug">
<Appenders>
<Console name="log-test" target="SYSTEM_OUT">
<PatternLayout pattern="%d{DATE} %-5p LJX2 %c{1}: %m%n" />
</Console>
</Appenders>
<Loggers>
<Logger name="top.Log4J2TestApp" level="debug" additivity="false">
<AppenderRef ref="log-test" />
</Logger>
<Root level="trace">
<AppenderRef ref="log-test" />
</Root>
</Loggers>
</Configuration>
My test program:
package top;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
public class Log4J2TestApp {
public static void main(String[] args) {
System.out.println("******** Started ZZZ ****************");
Logger log = LogManager.getLogger(Log4J2TestApp.class);
int cnt = 0;
while (true) {
log.warn("=========== Test message: {} ================", cnt++);
Thread.sleep(1000);
}
}
}
The output of the test program looks like this:

Your config looks good, the only thing a bit suspicious is the error. The error does seem to occur in the LoggerContext constructor, so it may be related after all.
You may have found a bug. Would you mind reporting this issue in the log4j2 issue tracker so the log4j team can look at it?

Log4j2 uses ClassLoaderContextSelector as ContextSelector by default. In some cases (it is not clear for me, may be for simple applications like yours) it returns nothing as getLoggerContexts() method call result. No logger contexts - nothing no show, so LoggerContext category doesn't present in the tree. It can be fixed by selecting another ContextSelector implementation. I used org.apache.logging.log4j.core.selector.BasicContextSelector for this purpose. It can be set using system property named "Log4jContextSelector". See docs for more info.
It solves my problem, I hope it helps to solve yours too.
