Hello all,
I am back again. After getting my restful services to migrate from 1.3 to
1.4, my problems now lie on the client side. I am using the following
service and POJO:
@Path("/report")
public interface ReportService {
@GET
@Path("/list")
@Produces(MediaType.APPLICATION_JSON)
public List<ReportDefinition> findAllReports();
}
@XmlRootElement
public class ReportDefinition implements Serializable{
private static final long serialVersionUID = 3244207063649073532L;
private String reportName;
private String reportDisplayName;
private List<ParameterDefinition> parameterList;
public ReportDefinition(){
}
public ReportDefinition(String reportName){
super();
this.reportName = reportName;
}
public ReportDefinition(String reportName, String reportDisplayName){
super();
this.reportName = reportName;
this.reportDisplayName = reportDisplayName;
}
public String getReportName() {
return reportName;
}
public void setReportName(String reportName) {
this.reportName = reportName;
}
public String getReportDisplayName() {
return reportDisplayName;
}
public void setReportDisplayName(String reportDisplayName) {
this.reportDisplayName = reportDisplayName;
}
public List<ParameterDefinition> getParameterList() {
return parameterList;
}
public void setParameterList(List<ParameterDefinition> parameterList) {
this.parameterList = parameterList;
}
public void addParameterDefinition(ParameterDefinition
parameterDefinition){
if(parameterList == null){
parameterList = new ArrayList<ParameterDefinition>();
}
parameterList.add(parameterDefinition);
}
}
Here is my Json Provider configuration:
<osgi:reference id="reportService"
interface="org.syntech.reports.shared.services.ReportService" />
<osgi:service
interface="org.syntech.reports.shared.services.ReportService">
<osgi:service-properties>
<entry key="service.exported.interfaces" value="*" />
<entry key="service.exported.configs"
value="org.apache.cxf.rs" />
<entry key="service.exported.intents" value="HTTP" />
<entry key="org.apache.cxf.rs.databinding" value="jaxb"
/>
<entry key="org.apache.cxf.rs.in.interceptors"
value="org.apache.cxf.interceptor.LoggingInInterceptor" />
<entry key="org.apache.cxf.rs.out.interceptors"
value="org.apache.cxf.interceptor.LoggingOutInterceptor" />
<entry key="org.apache.cxf.rs.provider">
<array>
<ref bean="jsonProvider" />
</array>
</entry>
<entry key="org.apache.cxf.rs.address"
value="${address-base-url}/ReportService" />
</osgi:service-properties>
<ref bean="reportService" />
</osgi:service>
<bean id="jsonProvider"
class="org.apache.cxf.jaxrs.provider.json.JSONProvider" >
<property name="singleJaxbContext" value="true" />
<property name="marshallAsJaxbElement" value="true"/>
<property name="unmarshallAsJaxbElement" value="true" />
</bean>
The following json is produced ( and used to work fine in 1.3 ):
{
"reportDefinition":
[
{
"parameterList":
[
{
"defaultValue": "ZARC",
"multiValue": false,
"parameterName": "Site",
"parameterType":
"org.syntech.reports.shared.domain.StringParameter",
"required": true
},
{
"defaultValue": "%",
"multiValue": true,
"parameterName": "Tank",
"parameterType":
"org.syntech.reports.shared.domain.StringParameter",
"required": true
}
],
"reportDisplayName": "Title Unavailable",
"reportName": "LastTankInfo"
},
{
"parameterList":
[
{
"defaultValue": "%",
"multiValue": true,
"parameterName": "SiteID",
"parameterType":
"org.syntech.reports.shared.domain.StringParameter",
"required": true
},
{
"defaultValue": "#CCCCCC",
"multiValue": false,
"parameterName": "backGroundColor",
"parameterType":
"org.syntech.reports.shared.domain.StringParameter",
"required": true
},
{
"defaultValue": "2012-12-12",
"multiValue": false,
"parameterName": "EndTime",
"parameterType":
"org.syntech.reports.shared.domain.DateParameter",
"required": true
},
{
"defaultValue": "2010-12-12",
"multiValue": false,
"parameterName": "StartTime",
"parameterType":
"org.syntech.reports.shared.domain.DateParameter",
"required": true
}
],
"reportDisplayName": "Site Inventory",
"reportName": "SiteInventory"
}
]
}
Here is my client side configuration (worked in 1.3 ):
<jaxrs:client id="jaxrsReportService"
address="${jaxrs-syntech-reports.base-url}"
serviceClass="org.syntech.reports.shared.services.ReportService"
inheritHeaders="true">
<jaxrs:inInterceptors>
<bean
class="org.apache.cxf.interceptor.LoggingInInterceptor" />
</jaxrs:inInterceptors>
<jaxrs:outInterceptors>
<bean
class="org.apache.cxf.interceptor.LoggingOutInterceptor" />
</jaxrs:outInterceptors>
<jaxrs:properties>
<entry key="org.apache.cxf.output.buffering" value="false"/>
</jaxrs:properties>
<jaxrs:providers>
<ref bean="jsonProvider" />
</jaxrs:providers>
</jaxrs:client>
<bean id="jsonProvider"
class="org.apache.cxf.jaxrs.provider.json.JSONProvider" >
<property name="singleJaxbContext" value="true" />
<property name="marshallAsJaxbElement" value="true"/>
<property name="unmarshallAsJaxbElement" value="true" />
</bean>
When I debug the code, It fails when it hits the following code in
JSONProvider:
if (isCollection) {
response =
((CollectionWrapper)response).getCollectionOrArray(theType, type,
org.apache.cxf.jaxrs.utils.JAXBUtils.getAdapter(theGenericType, anns));
}
*isCollection* = true
*theType* = class org.syntech.reports.shared.domain.ReportDefinition
*type* = java.util.List
*theGenericType* = class org.syntech.reports.shared.domain.ReportDefinition
*anns* = [@javax.ws.rs.GET(), @javax.ws.rs.Path(value=/list),
@javax.ws.rs.Produces(value=[application/json])]
Where it fails: it tries to cast my ReportDefinition class to
org.apache.cxf.jaxrs.provider.AbstractJAXBProvider$CollectionWrapper
This doesnt seem right to me, shouldn't it try to cast the List to the
CollectionWrapper?
Is there some more parameters I need to add to my server/client JSONProvider
configurations?
Thanks,
Neil
