could not find writer for content-type application/xml type:

[Elangovan Shanmugam]

Hi all,

I am trying to develop client side code for my RestEasy RESTful web service. When I am trying to create a (POST) request with my complex xml type, I am getting the following error. Could you please throw some tips why would this happen? or What am I doing wrong.

Caused by: java.lang.RuntimeException: could not find writer for content-type application/xml type: com.company.dto.someObj
	at org.jboss.resteasy.client.ClientRequest.writeRequestBody(ClientRequest.java:409)
	at org.jboss.resteasy.client.core.executors.ApacheHttpClientExecutor$ClientRequestEntity.<init>(ApacheHttpClientExecutor.java:117)
	at org.jboss.resteasy.client.core.executors.ApacheHttpClientExecutor.loadHttpMethod(ApacheHttpClientExecutor.java:188)
	at org.jboss.resteasy.client.core.executors.ApacheHttpClientExecutor.execute(ApacheHttpClientExecutor.java:56)

	at org.jboss.resteasy.client.ClientRequest.httpMethod(ClientRequest.java:590)
	at org.jboss.resteasy.client.core.ClientInvoker.invoke(ClientInvoker.java:102)

I did check the generated DTO (JAXB) object, and it does have the @XMLRootElement and other annotations.

Thanks

I resolved this a while back and thought post the answer to this thread as well.

Solution: Just add the jaxb-provider dependency to the client project, something like as follows. Even though this is not required for compile time, this is needed for the run-time, in the above situation.

        <dependency>
            <groupId>org.jboss.resteasy</groupId>
            <artifactId>resteasy-jaxb-provider</artifactId>
            <version>1.2.1.GA</version>
        </dependency>

Thanks
