Class JSR181Helper

java.lang.Object
  org.apache.axis2.jsr181.JSR181Helper

public abstract class JSR181Helper
extends Object

Helper class to work with JSR 181 annotations. This class should be used to retrieve JSR 181 annotations. It avoids the direct dependency on the API, i.e. it avoids NoClassDefFoundError exceptions if the JAR is not in the classpath. This is useful because these annotations are completely optional in Axis2.
