We are migrating from log4j to log4j2. We use the following libraries and there logging mechanisms:
Tomcat (which uses JULI), Spring 4.2.0 (which uses commons-logging) and Hibernate 4.3.11-Final (which uses jboss-logging).
I have successfully got Spring bridging to log4j2, but Hibernate logging is not working.
According to the Hibernate docs:
To use JBoss Logging with Log4j2, the log4j2 jar would also need to be available on the classpath.
I have the following logging-related jars on my classpath:
commons-logging-1.2.jar
jboss-logging-3.1.3.GA.jar
jboss-logging-annotations-1.2.0.Beta1.jar
log4j-api-2.6.1.jar
log4j-core-2.6.1.jar
log4j-jcl-2.6.1.jar
log4j-slf4j-impl-2.6.1.jar
slf4j-api-1.7.5.jar
slf4j-log4j12-1.7.5.jar
Any ideas why I'm not seeing the results I expect?
The version of jboss-logging included with hibernate-4 is not compatible with log4j2.
I had to import version 3.3.0.Final (should work starting with 3.1.4, according to JBLOGGING-94) for hibernate to work with log4j2.
Here is a shortcut if you use maven :
<dependency> <!-- version working with log4j2 -->
<groupId>org.jboss.logging</groupId>
<artifactId>jboss-logging</artifactId>
<version>3.3.0.Final</version>
<scope>runtime</scope>
</dependency>

Anyone could englighten me which org.apache.camel version I should use with the Spring boot version 2.0.0 .RELEASE.
When I used newer versions of apache.camel such like 2.21.0 , I come across with RelaxedPropertyResolved error. I read the forums and I was told to downgrade the version of Spring Boot which I cant. I have to use sprint.boot.version 2.0.0 with a new apache.camel.version without making changes at my java code ?
Do you think is it possible?
These are my dependecies for camel.version and spring.boot.version. Please let me know if you need anything more.
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-bom</artifactId>
<version>${camel.version}</version>

<artifactId>spring-boot-starter-parent</artifactId>

i have created spring rest services using eclipse IDE. It works fine in eclipse when i run using Debug configurations however when I export it as a executable JAR and run using below command
java -jar cs.jar
it gives me below error:

why it's not working as a jar?
You need to check if you have included servlet-api jar in your classpath, if yes, delete it.
If servlet-api is in classpath, it is included in WEB-INF/lib and then the error is thrown because servlet container has already servlet api jar.
Delete servlet-api dependency from maven or gradle if exits or if this dependency is adding by any other module then exclude servlet api dependency like below
<dependency>
<groupId><groupId></groupId>
<artifactId><some dependency></artifactId>
<version><version></version>
<exclusions>
<exclusion>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
</exclusion>
</exclusions>
</dependency>
I'm building a web app using Vaadin and it needs to communicate with several REST APIs. I've set it up in IntelliJ with Maven. I was thinking for the REST client I would use GSON to parse the JSON objects I'd be receiving from the open APIs, however, the application crashes due to a servlet exception error.
Caused by:
java.lang.ClassNotFoundException: com.google.gwt.json.client.JSONObject
I've added the GSON dependency to the pom.xml:
<dependency>
<groupId>com.google.code.gson</groupId>
<artifactId>gson</artifactId>
<version>2.3.1</version>
</dependency>
And have tried changing the module settings from Provided to Compiled to Runtime but with no change.
I'm just stumped as to why the GSON jar appears in the project dependencies within IntelliJ using Maven but fails on run time. I've seen references to Eclipse and including the jar in the classpath but, again, I'm using IntelliJ/Maven to build my Vaadin project and satisfy dependencies.
Any help is greatly appreciated!
Add below dependency in your classpath:
<dependency>
<groupId>com.google.gwt</groupId>
<artifactId>gwt-user</artifactId>
<version>2.3.0</version>
</dependency>
I am trying to use spring boot 1.1.5 and apache spark 1.0.2 together in project. Look like apache spark uses Jetty container internally and I have configured spring-boot to use Tomcat container. However application startup fails with some securityException at root cause. If I see full stack trace looks like spring boot trying to initialize "jettyEmbeddedServletContainerFactory" which it shouldn't in first place. It probably picks it up from classpath due to jetty presence via spark. If I exclude jetty from spark and run again I don't see same error again but then SparkContext initialization fails due to not finding jetty. How do i tell spring-boot runtime to look for "TomcatEmbeddedServletContainerFactory" instead of jetty one?
I got "java.lang.SecurityException: class "javax.servlet.http.HttpSessionIdListener"'s signer information does not match signer information of other classes in the same package"
To fix this issue I was need to remove all javax.servlet dependencies.
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-core_2.10</artifactId>
<version>1.3.1</version>
<exclusions>
<exclusion>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
</exclusion>
<exclusion>
<groupId>org.glassfish</groupId>
<artifactId>javax.servlet</artifactId>
</exclusion>
<exclusion>
<groupId>org.eclipse.jetty.orbit</groupId>
<artifactId>javax.servlet</artifactId>
</exclusion>
</exclusions>

#Joakim Erdfelt, Thanks.
I was just waiting to see if someone is familiar with this situation and if it's just a small configuration change. As it turns out it is! #Configuration
#EnableAutoConfiguration(exclude={EmbeddedServletContainerFactory.class})
public class MyConfiguration { }
I defined my own "EmbeddedServletContainerFactory" bean as a "org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedServletContaine‌​rFactory" and it started working as I expected.
I'm having some trouble trying to include Apache POI poi-ooxml library to my project. I'm using Maven and the following dependency:
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml</artifactId>
<version>3.8</version>
</dependency>
But after doing this I'm not able to start my Spring MVC app again, Here is the stacktrace:
Exception created : org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from ServletContext resource [/WEB-INF/context/applicationContext.xml]; nested exception is javax.xml.parsers.FactoryConfigurationError: Provider for javax.xml.parsers.DocumentBuilderFactory cannot be found
So, what I understand is that poi-ooxml is including another xml parser that override the default Java VM defaut one that is used by Spring to read its xml configuration file.
If I exclude the 2 following libs:
xmlbeans
xml-apis
All is working fine (I'm able to start my Spring app) but of course Apache POI is no longer working as he's missing these 2 required libs...
Any advice will be greatly appreciated ;)
Thanks
I've had similiar problem after adding poi-ooxml to my existing groovy application. I've added xercesImpl to project, and it seems to be working. Maybe you should give it a try.
<dependency>
<groupId>xerces</groupId>
<artifactId>xercesImpl</artifactId>
<version>2.9.1</version>
</dependency>
