CXF ClassNotFoundException: javax.ws.rs.MessageProcessingException

Question

I'm trying to start a jax ws & rs server endpoints, I can get them started using rs-api 2.0 (and version 2.0.1) but when I try to make a request it throws

java.lang.NoClassDefFoundError: javax/ws/rs/MessageProcessingException  

There are some other threads in SO regarding this matter but the suggestions don't work for me. Using any of the rs-api 2 milestone versions throws issues

Exception in thread "main" java.lang.NoClassDefFoundError: javax/ws/rs/BadRequestException

I'm running this as a java application, not a webapp. Anyone have any ideas to try? Thanks

EDIT: My dependencies. I added jsr311 but that did not change the MessageProcessingException

Answer 1

Faced the same issue, but later when I used 3.0.0-milestone2 of cxf-bundle with 2.1-m01 of javax.ws.rs-api , it worked like a charm.

<dependency>
    <groupId>javax.ws.rs</groupId>
    <artifactId>javax.ws.rs-api</artifactId>
    <version>2.1-m01</version>
</dependency>

<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-bundle</artifactId>
    <version>3.0.0-milestone2</version>
</dependency>

Answer 2

<dependency>
<groupId>javax.ws.rs</groupId>
<artifactId>javax.ws.rs-api</artifactId>
<version>2.0-m10</version>
</dependency>

This version has support for javax.ws.rs.MessageProcessingException class.

I took this same error using Jersey client without JSON/JAXB providers to do the calls to server, when I configure Jettison provider the problem was solved. This erros also occour when I use a incompatible POJO to marshaling object to call service. check it. I hope this help.

The problem also occur when you have Classloader problems, check your maven dependecy hierarchy conflicts of jax-rs. In my case I need to use exlcusion filter in my pom.xml like

<exclusions>
    <exclusion>
        <artifactId>javax.ws.rs-api</artifactId>
        <groupId>javax.ws.rs</groupId>
    </exclusion>
</exclusions>

I made exclusion in cxf-bundle-jaxrs in another project that uses javax.ws.rs-api dependency. Using dependency of cxf-rt-frontend-jaxrs:2.7.11 was sufficient.

Answer 4

I had the same issue & I had to add this exclusion -

            <exclusion>
                <groupId>org.apache.cxf</groupId>
                <artifactId>cxf-rt-frontend-jaxrs</artifactId>
            </exclusion>
