调用ejb+Resteasy的rest服务报错：Could not find MessageBodyWriter

Could not find MessageBodyWriter for response object of type: java.util.ArrayList

解决办法：war包要包含提供rest服务的ejb LOCAL接口类

我的打包参考：

1、build.ejblocal.xml片段

<target name="ejb-local.jar">
		<jar jarfile="${temp.dir}/ejb-local.jar">
			<fileset dir="./${classes.dir}">
				<include name="**/IHelloWorldLocal.class" />
				<include name="**/Book.class" />
				<!--include name="**/jboss-deployment-structure.xml" /-->
				
			</fileset>
		</jar>
	</target>

说明：IHelloWorldLocal是ejb LOCAL接口，包含rest声明，类中有一个方法，返回值为List<Book>；Book是vo类。打包生成ejb-local.jar

2、build.ejbimpl.xml片段

<target name="ejb-impl.jar">
		<jar jarfile="${temp.dir}/ejb-impl.jar">
			<fileset dir="./${classes.dir}">
				<include name="**/HelloWorldBean.class" />
				<include name="**/jboss-deployment-structure.xml" />
				
			</fileset>
		</jar>
	</target>

说明：HelloWorldBean是IHelloWorldLocal的实现类。打包生成ejb-impl.jar。

jboss-deployment-structure.xml如下，声明了对ejb-local.jar的依赖

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.1">
  <deployment>

    <dependencies>
		<module name="deployment.ejb-local.jar" />
    </dependencies>
    
  </deployment>
</jboss-deployment-structure>

3、build.war.xml片段

        <target name="deploy-war">
		<jar jarfile="${temp.dir}/rest.war">
			<fileset dir="./web/">
				<include name="**/IHelloWorldLocal.class" />
				<include name="**/web.xml" />
				<include name="WEB-INF/jboss-deployment-structure.xml" />
				
			</fileset>
		</jar>
	</target>

说明：如果不包含<include name="**/IHelloWorldLocal.class" />，调用rest服务就会报上面的错误
web.xml中Resteasy的配置：

 	 <context-param>
		<param-name>resteasy.jndi.resources</param-name>
		<param-value>
			java:global/ejb-impl/HelloWorldBean!com.ejb.hello.IHelloWorldLocal
		</param-value>
	</context-param>
	 <context-param>
		<param-name>resteasy.servlet.mapping.prefix</param-name>
		<param-value>/rest</param-value>
	</context-param>

 	<context-param>
		<param-name>resteasy.scan</param-name>
		<param-value>true</param-value>
	</context-param>

	<listener>
		<listener-class>org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap</listener-class>
	</listener>

	<servlet>
		<servlet-name>Resteasy</servlet-name>
		<servlet-class>org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher</servlet-class>
	</servlet>
	
	<servlet-mapping>
		<servlet-name>Resteasy</servlet-name>
		<url-pattern>/rest/*</url-pattern>
	</servlet-mapping>

WEB-INF/jboss-deployment-structure.xml的配置：

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.1">
  <deployment>
    <dependencies>
		<module name="deployment.ejb-local.jar" />
<!-- 		<module name="org.jboss.resteasy.resteasy-jettison-provider"/>
		<module name="org.jboss.resteasy.resteasy-jackson-provider"/> -->
		<module name="org.jboss.resteasy.resteasy-jaxrs" />
		<module name="org.jboss.resteasy.resteasy-jaxb-provider" />
    </dependencies>
  </deployment>
</jboss-deployment-structure>
