NoClassDefFoundError

Burg, Yaron

Hi,

 

My name is Yaron and I’m currently working on a project which involves the usage of REST API calls.

I’m trying to use Wink client from Java , using Eclipse (java application project or servlet).

I added wink-client, wink-commons and jsr311-api to the referenced libraries and the dependency in pom.xml. The code passes compilation.

Currently I use the source code from the QA Defects example.

 

However, when I execute it, I always get

java.lang.NoClassDefFoundError: org/apache/wink/client/RestClient

 

Have you ever heard of this error? Am I doing something wrong?

 

Thanks,

Yaron.

Re: NoClassDefFoundError

NoClassDefFoundError means that some third-party of RestClient is missing.

The third parties of the RestClient are:
org.apache.wink:wink-client:jar:1.0-incubating
+- org.apache.wink:wink-common:jar:1.0-incubating:compile
|  \- javax.ws.rs:jsr311-api:jar:1.0:compile
+- org.slf4j:slf4j-api:jar:1.5.8:compile
+- org.slf4j:slf4j-simple:jar:1.5.8:compile
+- javax.xml.bind:jaxb-api:jar:2.1:compile
|  \- javax.xml.stream:stax-api:jar:1.0-2:compile
+- com.sun.xml.bind:jaxb-impl:jar:2.1.4:compile
+- javax.activation:activation:jar:1.1:compile

So if you are running Java 6, you are probably missing Slf4j.
If you are running Java 5, you may be also missing Jaxb and activation.

Hope it helps,
Michael.
