java apache-axis classnotfoundexception tomcat9 axiom

How to resolve ClassNotFoundException with specific Axis2 and Axiom combinations in Tomcat 9 and Java 11?

Hello StackOverflow community,

I'm having difficulties with my web project running on Apache Tomcat 9.0.62, using Java 11. My application uses the Axis2 (1.7.9) and Axiom (1.4.0) libraries for the creation and manipulation of web services.

During runtime, I'm encountering two ClassNotFoundException errors. Here are the full errors:

java.lang.ClassNotFoundException: org.apache.axiom.soap.impl.builder.OMMetaFactoryEx
java.lang.ClassNotFoundException: org.apache.axis.transport.http.AdminServlet

Full error:

I've experimented with various combinations of the Axis and Axiom libraries, from Axis 1.6 to Axiom 1.3. Based on my project requirements and compatibility, Axis 1.7.9 and Axiom 1.4.0 work best for me. Despite these efforts, and also attempting to add the JAR files manually both to the project and to the Tomcat server, the errors persist.

Here are the additional details of my setup:

JDK: 11
Server: Apache Tomcat 9.0.62
Libraries:
- Axis2: 1.7.9
- Axiom: 1.4.0

Has anyone faced this issue before or have any idea on how to solve these ClassNotFoundException errors? Any suggestion is greatly appreciated.

Thanks in advance.

Solution

I was finally able to solve my problem, which was being affected by three key factors.

Axis2 and Axiom Versions: I had to revert back to older versions of axis2 and axiom to avoid conflicts. The versions that finally worked for me are as follows:
```
<axiom.version>1.2.13</axiom.version>
<axis2.version>1.6.2</axis2.version>
```
Library Load Order: The order in which libraries were loading in my project was also affecting things. Be sure to check and adjust this as needed in your own project.

JDK 11 Incompatibilities: I also ran into an issue where javax.xml.stream was accessible by more than one module. To fix this, I had to exclude the following libraries from my dependencies:

<dependency>
    <groupId>org.apache.ws.commons.axiom</groupId>
    <artifactId>axiom-api</artifactId>
