-------------------------------------
Summary: ServiceInterfaceStrategy fails to create with interface
containing multiple methods without parameters
Key: CAMEL-6716
URL: https://issues.apache.org/jira/browse/CAMEL-6716
Project: Camel
Issue Type: Bug
Components: camel-soap
Affects Versions: 2.12.0
Reporter: Ondrej Fischer
Priority: Blocker
I you attempt to create a ServiceInterfaceStrategy with interface containing
multiple methods without parameters, you get NullPointerException.
It's due to following code:
ServiceInterfaceStrategy.java:161
{code}
155 private void analyzeServiceInterface(Class<?> serviceInterface) {
156 Method[] methods = serviceInterface.getMethods();
157 for (Method method : methods) {
158 MethodInfo info = analyzeMethod(method);
159 for (int i = 0; i < info.getIn().length; i++) {
160 TypeInfo ti = info.getIn()[i];
161 if (inTypeNameToQName.containsKey(ti.getTypeName())
162 && (!(ti.getTypeName().equals("javax.xml.ws.Holder")))
163 &&
(!(inTypeNameToQName.get(ti.getTypeName()).equals(ti.getElName())))) {
164 LOG.warn("Ambiguous QName mapping. The type [ "
165 + ti.getTypeName()
166 + " ] is already mapped
to a QName in this context.");
167 continue;
168 }
169 inTypeNameToQName.put(ti.getTypeName(), ti.getElName());
170 }
171 if (info.getSoapAction() != null &&
!"".equals172(info.getSoapAction())) {
172 soapActionToMethodInfo.put(info.getSoapAction(), info);
173 }
174
175 outTypeNameToQName.put(info.getOut().getTypeName(),
info.getOut().getElName());
176
177 addExceptions(method);
178 }
179 }
{code}
For the second method without parameters, the null value is already in the
inTypeNameToQName, so it tries to evaluate this:
!(ti.getTypeName().equals("javax.xml.ws.Holder"), which fails with NPE.
The question here is, why method without parameters still needs an array of
types containing one element with those null values.
