Wicket (9.8.0) application using EJB injection throws exception while deploying on Payara 5.201

I am trying to use WicketTester for application containing EJB injection related code.
I created application using 'wicket.apache.org/start/quickstart.html', and deployed it on Payara server '5.201'.
Deployment was successful, and I was able to see the page on web browser.
Tests written for the page were also executed successfully.
Once that was done, I added following dependencies in POM.xml
<dependency>
<groupId>jakarta.platform</groupId>
<artifactId>jakarta.jakartaee-api</artifactId>
<version>${jakartaee}</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.wicketstuff</groupId>
<artifactId>wicketstuff-javaee-inject</artifactId>
<version>${wicket.version}</version>
<scope>provided</scope>
</dependency>
I set properties in pom file as follows
<properties>
<wicket.version>9.8.0</wicket.version>
<jakartaee>8.0.0</jakartaee>
</properties>
In the class extending 'WebApplication' I added following import
import org.wicketstuff.javaee.injection.JavaEEComponentInjector;
And in overridden 'init' method added following statement
getComponentInstantiationListeners().add(new JavaEEComponentInjector(this));
Complete project can be found at 'https://github.com/rjngshn/WicketTesterEJB'.
Before adding any stateless bean, I wanted to ensure my application still deploys properly.
However I noticed that it does not. Following exception was logged.
Can anyone please help?

I doubt that Payara server provides wicketstuff artefacts.

Is there any specific reason why this is happening or what and where i should look as i am really clueless as to why change in camel results in spring's class not being found?
And apart from this, all my routes made in java configuration are not working and throw exceptions like consumer not found for endpoint for all the routes that consume message from given endpoint but same seems to work in when writen in xml. Is there any reason for this? I am using camel 2.13.2 and java configuration for routes is done by extending RouteBuilder, also i have other routes that are already written in xml and the xml has been added in contextConfigLocation. Is it somehow related to adding xml in contextConfig?

camel-jms:2.18.1 component uses spring-jms with version 4.3.4.RELEASE. You need to upgrade to spring 4.3.4.RELEASE or migrate camel-jms component to camel-sjms, which does not use spring. You can find all relevant dependencies in camel-parent-2.18.1.pom
If you are using Maven, the best way to keep your dependencies consistent is using BOM:
<dependencyManagement>
<dependnecies>
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-parent</artifactId>
<version>2.18.1</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependnecies>
</dependencyManagement>
and then exclude version for all camel and spring related dependencies, which you are using in application.
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-core</artifactId>
</dependency>
...
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
</dependency>

Java jersey 2 json support

I am trying to create a rest web service which consumes JSON as input. Up to now I have not been able to do so as I get several exceptions. As I am not a maven user, it is so hard to handle dependencies and the documentation is not very helpful. The example that I use as reference is from mkyong website
Please is there anyone who has managed to enable json support in jersey 2 ? Any advice would be extremely helpful as I've reached a dead end. Bellow are my jars and my exception.

I had a hard time figuring out how to get the dependencies for Jersey 2 configured. I use Maven (recommended) and I know you said you weren't using it but I can show you how my pom.xml is set up and what mvn dependency:list says are my dependencies (only relevant part of pom.xml shown):

Resteasy deploy fails randomly on glassfish 4.1

I have a problem with my REST-Application using Resteasy.
When I deploy the application with this dependencies
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-servlet-initializer</artifactId>
<version>3.0.11.Final</version>
</dependency>
as described here in Chapter 3.5 sometimes the server deploys the application correctly and everything works fine.
But sometimes I get
Error invoking ServletContainerInitializer

java.lang.NullPointerException

In the sources of ResteasyServletInitializer line 109 is this (with context)
ServletRegistration.Dynamic reg = servletContext.addServlet(applicationClass.getName(), HttpServlet30Dispatcher.class);
reg.setLoadOnStartup(1); //Line 109
reg.setAsyncSupported(true);
reg.setInitParameter("javax.ws.rs.Application", applicationClass.getName());
So I assume this is a Glassfish bug and Glassfish fails to properly return the correct object.
I have not found that this happens with redeployments, after clearing osgi-cache, etc. It seems to be pretty random.
This seems to be related and I tried adding
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
<scope>provided</scope>
</dependency>
But it still fails sometimes although I would say it fails a little bit less often.
The accepted answer from the post is deprecated as by the resteasy reference 3.9. RESTEasy as a ServletContextListener so I do not want to try this.
This seems like avoiding the problem, not solving it.
My Glassfish version is GlassFish Server Open Source Edition 4.1 (build 13).
Please help me with this one.
Cheers

I ended up avoiding this issue by ensuring the application WAR did not include RESTEasy.
So I build two wars now: one with RESTEasy (as required for deploying on Tomcat and Wildfly), another without (for deploying on Glassfish). That seems better than requiring changing the Glassfish install, but accomplishes the same: avoids having two JAX-RS implementations installed.

java.lang.NoClassDefFoundError: org/apache/http/impl/conn/PoolingClientConnectionManager

Getting an issue with this dependency although it isn't being referenced as a dependency explicitly in my pom.xml. The actual maven dependency is:
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.2.5</version>
</dependency>
The stacktrace from my console is:

I have tried deleting my .m2/repositories directory and downloading my dependencies (through maven) and it still doesn't work.

Your problem is probably nothing to do with dependencies. NoClassDefFoundError is different to ClassNotFoundException. It means that the class was available while compiling, but failed to initialise, usually due to an exception in a static block. This answer has the good oil. What causes and what are the differences between NoClassDefFoundError and ClassNotFoundException?

Try upgrading to 4.3
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.3.3</version>
</dependency>
I think the class was not present until 4.3

Try by changing the httpClient version from 4.2.5 to 4.3.4... It worked for me...

As it works for me, please post your original pom. Also check if you are behind a proxy and your .m2/settings is valid.

Please check the version of the servlet-api that you are using in your project and also in the poms of the third party jars like Spring-web, httclient etc. If spring jar is compiled with servlet version 3.0.1 and httpclient or its dependencies are compiled with servlet 2.5.6 then this problem might occur.
I have faced similar issue while upgrading some of the third party dependencies for my project.
