remoting with spring dm server

[vishalj]

I am trying to get the remote service up and running on a dm server through "org.springframework.remoting.httpinvoker.HttpInvo kerServiceExporter"

But the service is not available while accessing through client [500 error]


In WEB-INF/spring/service.xml

<bean name="accountExporter" class="org.springframework.remoting.httpinvoker.HttpInvokerServiceExporter">
<property name="service" ref="accountService"/>
<property name="serviceInterface" value="example.AccountService"/>
</bean>

In web.xml

<servlet>
<servlet-name>accountExporter</servlet-name>
<servlet-class>org.springframework.web.context.support.HttpRequestHandlerServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>accountExporter</servlet-name>
<url-pattern>/remoting/AccountService</url-pattern>
</servlet-mapping>

On client side

<bean id="myclient" class="com.pg.remote.client.MyClient" init-method="init">
		<property name="accountService" ref="httpInvokerProxy"></property>
	</bean>
	<bean id="httpInvokerProxy"	class="org.springframework.remoting.httpinvoker.HttpInvokerProxyFactoryBean">
		<property name="serviceUrl"	value="http://localhost:8080/remote/remoting/AccountService" />
		<property name="serviceInterface" value="com.pg.remote.server.AccountService" />
	</bean>

Can you post your stacktrace, normally that is quite informative. Also make sure that your application starts correctly...

Please use [ code][/code ] tags when posting code/xml/stacktraces...

This seems to be the clientside configuration, there must be however also some server side error...

[vishalj]

No the server side is being succesfully deployed
The remoting service is a part of web bundle and am able to access other web content

[vishalj]

Sorry the server side was giving run time error and its solved now
Thanks for the Replies

Hi there,

I have some questions on this, please understand I am a newbie:

1. Did you build your project using eclipse? If yes, did you export it as a deployable jar and rename it to war extension after the export?
2. Where did you put the web.xml, I assume it is in /WEB-INF/, correct?
3. If you don't mind, could you please forward me your entire project on this to my email address because I really wanna know the hierarchy of this project?

Please help me. Thank you.

Jeff,

Hi Jeff,
1.I did build the jar using ant .and yes it was just a jar not a war
2.Yes the web.xml was in WEB-INF/
3.Sure will upload the sample here itself

Regards,
vishal
