Using cxf-spring-boot-starter-jaxrs WebClient with TLS produces Certificate Unknown Error

If I am using the below maven dependency, in combination with TLS, then I am getting an Certificate Unknown Error.:
<dependency>
<groupId>org.apache.cxf</groupId>
<type>pom</type>
<artifactId>cxf-spring-boot-starter-jaxrs</artifactId>
<version>3.1.12</version>
</dependency>
If I am using the below maven dependency, then everthing works as expected.:
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-rs-client</artifactId>
<version>3.1.12</version>
</dependency>
Even more worse, if I am adding the below dependency, then I am getting the same Error again:
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-spring-boot-starter-jaxws</artifactId>
<type>pom</type>
</dependency>
I am not sure, what the problem is, but maybe some cxf-spring-boot auto-configuration does produce the problem ?

I could verify the problem.
The difference is that the cxf.xml configuration gets not used in any case.
After explicitly importing the cxf.xml into my spring configuration, the problem was solved.

GAE - Class not found: Caused by: java.lang.ClassNotFoundExceptionAppIdentityCredential$AppEngineCredentialWrapper

I'm trying to launch a simple Java (Maven) Spring Boot application on GAE that communicates with an PostrgreSql server (also on the Cloud Platform) however I keep running into missing dependencies.
I had these dependencies in my pom:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-gcp-starter</artifactId>
<version>1.1.3.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-gcp-starter-sql-postgresql</artifactId>
<version>1.1.3.RELEASE</version>
</dependency>
But whenever I deployed the app to GAE and the FlyWay the following was thrown:
java.lang.ClassNotFoundException: com.google.appengine.api.ThreadManager
I mainly followed the Baeldung tutorial here: https://www.baeldung.com/spring-boot-google-app-engine.
Then I found this answer: AppEngine ClassNotFoundException: com.google.appengine.api.datastore.DatastoreServiceFactory
Which led me to adding the appengine dependency:
<dependency>
<groupId>com.google.appengine</groupId>
<artifactId>appengine-api-1.0-sdk</artifactId>
<version>1.9.77</version>
</dependency>
Which then throws:
ClassNotFoundException: com.google.api.client.googleapis.extensions.appengine.auth.oauth2.AppIdentityCredential$AppEngineCredentialWrapper
Which then led me to adding the client dependency.. and so on.. and so on..
My complete set of dependencies is now:
<dependency>
<groupId>com.google.cloud</groupId>
<artifactId>google-cloud</artifactId>
<version>0.47.0-alpha</version>
</dependency>
<dependency>
<groupId>com.google.appengine</groupId>
<artifactId>appengine-api-1.0-sdk</artifactId>
<version>1.9.77</version>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-gcp-starter</artifactId>
<version>1.1.3.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-gcp-starter-sql-postgresql</artifactId>
<version>1.1.3.RELEASE</version>
</dependency>
And that.. leads back to the exception above:
ClassNotFoundException: com.google.api.client.googleapis.extensions.appengine.auth.oauth2.AppIdentityCredential$AppEngineCredentialWrapper
So it is probably a dependency problem but I cannot for the life of my find any documentation about which dependencies you need to add to get a simple Spring Boot application running to a PostgreSQL server.
I'm about to throw in the towel...
It might be a lack of sleep though

You are missing the App Engine plugin in your pom.xml :
<build>
<plugins>
<plugin>
<groupId>com.google.cloud.tools</groupId>
<artifactId>appengine-maven-plugin</artifactId>
<version>1.3.2</version>
</plugin>
</plugins>
</build>
And for the exception you get, I do not know exactly where are you using this but you can add the dependency :
<dependency>
<groupId>com.google.auth</groupId>
<artifactId>google-auth-library-oauth2-http</artifactId>
<version>0.18.0</version>
</dependency>

JAVA - com.sun.xml.internal.messaging.saaj.soap.SAAJMetaFactoryImpl not found

I'm working on an application that consumes a web service using SOAP requests.
Sometimes I get this error:
filters.LoggerFilter:92 - org.springframework.web.util.NestedServletException: Handler processing failed; nested exception is java.lang.Error: javax.xml.soap.SOAPException: Unable to create SAAJ meta-factoryProvider com.sun.xml.internal.messaging.saaj.soap.SAAJMetaFactoryImpl not found
The weird part is that I get this error randomly, but I can't seem to figure out the cause.
I even added a new dependency, but it doesn't seem to correct the issue:
<dependency>
<groupId>com.sun.xml.messaging.saaj</groupId>
<artifactId>saaj-impl</artifactId>
<version>1.3</version>
</dependency>

I just had the same problem while using Java 11 to create an application that consumes SOAP-requests.
I added the new dependency and it worked fine for me.
<dependency>
<groupId>com.sun.xml.messaging.saaj</groupId>
<artifactId>saaj-impl</artifactId>
<version>1.5.1</version>
</dependency>

For me, I was using Java 13 and the following worked for me(add these in the pom.xml)
<dependency>
<groupId>org.glassfish.metro</groupId>
<artifactId>webservices-rt</artifactId>
<version>2.4.4</version>
</dependency>
<dependency>
<groupId>org.glassfish.metro</groupId>
<artifactId>webservices-api</artifactId>
<version>2.4.4</version>
</dependency>

For those who face this issue in intellij IDEA using Spring Boot under Java SDK 9+, you have to include explicitly --add-modules java.se.ee in VM parameters (edit configurations -> VM options). This answer may help to resolve other importing issues related to new Java Modules

I had the same problem.
For me, adding saaj-impl was not enough to get rid of the exception
<dependency>
<groupId>com.sun.xml.messaging.saaj</groupId>
<artifactId>saaj-impl</artifactId>
<version>1.5.2</version>
</dependency>
I had to also add saaj-api which fixed it finally:
<dependency>
<groupId>javax.xml.soap</groupId>
<artifactId>saaj-api</artifactId>
<version>1.3.5</version>
</dependency>
Since I realised that my application was using saaj-api 1.3.4 after checking with command, upgrading to 1.3.5 helped
mvn dependency:tree -Dverbose

Change your project sdk as Java 1.8
If you are using import javax.xml.ws library it could be confusing com.sun.xml.messaging.saaj dependency in Java 11. Clearing saaj dependency then using Java8 may be a solution in this issue

With open JDK 17 and spring boot 3.0.1, I was getting the same issue. It got resolved by adding these dependencies in pom.xml
<dependency>
<groupId>org.glassfish.metro</groupId>
<artifactId>webservices-rt</artifactId>
<version>2.4.4</version>
</dependency>
<dependency>
<groupId>org.glassfish.metro</groupId>
<artifactId>webservices-api</artifactId>
<version>2.4.4</version>
</dependency>

Vertx2: org.vertx.java.platform.impl.cli.Starter

I'm writing a "Hello-World" application in Vertx2.
I have the following dependencies in pom.xml:
<dependency>
<groupId>io.vertx</groupId>
<artifactId>vertx-core</artifactId>
<version>2.1.6</version>
</dependency>
<dependency>
<groupId>io.vertx</groupId>
<artifactId>vertx-platform</artifactId>
<version>2.0.0-beta1</version>
</dependency>
and run it as IntelliJ application with the following configuration:
I get the error:
Exception in thread "main" java.lang.NoSuchMethodError:
org.vertx.java.core.impl.VertxInternal.getOrAssignContext()Lorg/vertx/java/core/impl/DefaultContext;
Do you know what is the problem here?
Edit:
This project is for Vertx version 2 (not version 3). This is why the solution in this IntelliJ and Vertx: How to run org.vertx.java.deploy.impl.cli.Starter ? doesn't resolve the issue.

I found a solution to this problem. I just changed the version numbers for vertx-core and vertx-platform, and now it works.
The new dependencies in pom.xml are:
<dependency>
<groupId>io.vertx</groupId>
<artifactId>vertx-core</artifactId>
<version>2.1RC3</version>
</dependency>
<dependency>
<groupId>io.vertx</groupId>
<artifactId>vertx-platform</artifactId>
<version>2.1.5</version>
</dependency>

LocalTransportSender not found when using web services

I am not a big fan of web services, but sometimes you have to conform with a client interface. I have successfully generated code from the the provided WSDLs, but when I try and run the application which actually uses the generated classes, I get the following:
java.lang.ClassNotFoundException: org.apache.axis2.transport.local.LocalTransportSender
I am keeping the generated code in a separate project and have the following dependencies in my pom:
<dependencies>
<dependency>
<groupId>org.apache.axis2</groupId>
<artifactId>axis2-adb</artifactId>
<version>1.6.1</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.apache.axis2</groupId>
<artifactId>axis2-kernel</artifactId>
<version>1.6.1</version>
<scope>compile</scope>
</dependency>
</dependencies>
As stated, the jar gets generated without any issues, but when it is includes in the application that makes use of it, I get the said exception.
Any ideas?

Adding below dependency would probably should solve this problem.
<dependency>
<groupId>org.apache.axis2</groupId>
<artifactId>axis2-transport-local</artifactId>
<version>1.6.2</version>
</dependency>

Use next dependencies , and you should not have any problem
For api axis 2
axis2-adb
For runtime
axis2-transport-local
Laxis2-transport-http
