Hi all,

I am using the hessian and spring ,in server side i got the process completed successfully but in client i got the following error like

com.caucho.hessian.io.HessianProtocolException: '?' is an unknown code.


In web.xml
<servlet>
<servlet-name>transactionProcessing</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
<servlet-name>transactionProcessing</servlet-name>
<url-pattern>/transactionProcessing/*</url-pattern>
</servlet-mapping>


In transactionProcessing-servlet.xml

<bean id="transactionProcessingService" class="example.BatchServiceImpl">
<property name="txnprocess" ref="txnProcessingService"/>
</bean>


<bean name="/transactionservice" class="org.springframework.remoting.caucho.HessianService Exporter">
<property name="service" ref="transactionProcessingService"/>
<property name="serviceInterface" value="example.BatchServiceIntf"/>
</bean>
</beans>


My remote invoke call is

package com.sping.Hessian;

import com.caucho.hessian.client.HessianProxyFactory;

import example.BatchServiceIntf;

public class HessianCall {
public BatchServiceIntf getProxyBatchService() {
HessianProxyFactory factory = new HessianProxyFactory();
BatchServiceIntf batch = null;
try {
batch = (BatchServiceIntf) factory.create(BatchServiceIntf.class, "http://localhost:8080/SpringTest/transactionProcessing/transactionservice");

} catch (Exception e) {
e.printStackTrace();
}
return batch;
}
public static void main(String[] args) {
try {
HessianCall hessianObj = new HessianCall();
BatchServiceIntf proxyService = hessianObj.getProxyBatchService();
proxyService.test();
proxyService.test1();
}
catch (Exception e) {
e.printStackTrace();
}
}
}






Please kindly do some needful to fix the issue
