Description

In case we instantiate an Axis2 client without the axis2-jaxws dependency, we get the warning:

Warning

WARNING: Unable to instantiate deployer org.apache.axis2.deployment.ServiceDeployer; see debug logs for more details

It's caused by the block of code (424-451) in org.apache.axis2.deployment.AxisConfigBuilder

 

for (Iterator<OMElement> itr = element.getChildrenWithName(new QName(
TAG_SERVICE_BUILDER_EXTENSION)); itr.hasNext() {
...
catch (Throwable e) {
    log.warn("Unable to instantiate deployer " + deployerClassName
    + "; see debug logs for more details");
    log.debug(e.getMessage(), e);
    continue;
}

and is confusing: actually we were able to instantiate the deployer, we just were unable to load an extension for it.

The actual extension not being found is 

org.apache.axis2.jaxws.framework.JAXWSServiceBuilderExtension

It should be explicitly clear that the 

ServiceDeployer 

is ok.
