--------------------------------------
Thanks for looking into it :-)
> Member names must match bean attribute for BeanParam to work
> ------------------------------------------------------------
>
> Key: CXF-7267
> URL: https://issues.apache.org/jira/browse/CXF-7267
> Project: CXF
> Issue Type: Bug
> Affects Versions: 3.1.4
> Reporter: Daniel H. Peger
> Priority: Minor
>
> I just ran into this problem on my first attempt to use {{@BeanParam}} and
> got this exception:
> {noformat}
> java.lang.IllegalArgumentException: Unresolved variables; only 0 value(s)
> given for 2 unique variable(s)
> at
> org.apache.cxf.jaxrs.impl.UriBuilderImpl.substituteVarargs(UriBuilderImpl.java:285)
> at
> org.apache.cxf.jaxrs.impl.UriBuilderImpl.doBuildUriParts(UriBuilderImpl.java:121)
> ...
> {noformat}
> My parameter bean looked like this:
> {code}package com.recommind.common.rest;
> import javax.ws.rs.PathParam;
> public final class ApplicationIdentifierParameter
> {
> @PathParam("applicationId")
> private String mApplicationId;
> @PathParam("projectId")
> private String mProjectId;
> public String getApplicationId()
> {
> return mApplicationId;
> }
> public void setApplicationId(String aApplicationId)
> {
> mApplicationId = aApplicationId;
> }
> public String getProjectId()
> {
> return mProjectId;
> }
> public void setProjectId(String aProjectId)
> {
> mProjectId = aProjectId;
> }
> }
> {code}
> I debugged {{UriBuilderImpl}} and found that in {{ClientProxyImpl:514}} the
> to be evaluated members are identified by the names of the corresponding
> setters.
> I think this is wrong - or at least inconvenient - as it is totally valid for
> a bean's internals fields to have different names than the corresponding bean
> attribute. To my knowledge the Bean spec only requires setters and getters to
> match and does not care about the internal representation of the attributes.
> Rather than looking at the setters {{ClientProxyImpl}} should iterate over
> the bean's fields, look for fields annotated with {{@PathParam}} and update
> the field using reflection.
> *Workaround:*
> Annotate the setters with the {{@XXXParam}} annotations.
