Remoting with httpinvoker - EOFException thrown
Hello everybody,
i am using the httpinvoker für Remoting just like it is described in 2.5.4/reference/remoting.html
When I open the url for the service in the browser I get the Exception:
HTTP Status 500
When I try to use the service in my importer, i recieve the "HTTP Status 500" (Internal Server Error)Code:java.io.EOFException at java.io.ObjectInputStream$PeekInputStream.readFully(ObjectInputStream.java:2281) at java.io.ObjectInputStream$BlockDataInputStream.readShort(ObjectInputStream.java:2750) at java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:780) at java.io.ObjectInputStream.<init>(ObjectInputStream.java:280) at org.springframework.remoting.rmi.CodebaseAwareObjectInputStream.<init>(CodebaseAwareObjectInputStream.java:86) at org.springframework.remoting.rmi.CodebaseAwareObjectInputStream.<init>(CodebaseAwareObjectInputStream.java:71) at org.springframework.remoting.rmi.RemoteInvocationSerializingExporter.createObjectInputStream(RemoteInvocationSerializingExporter.java:105) at org.springframework.remoting.httpinvoker.HttpInvokerServiceExporter.readRemoteInvocation(HttpInvokerServiceExporter.java:115) at org.springframework.remoting.httpinvoker.HttpInvokerServiceExporter.readRemoteInvocation(HttpInvokerServiceExporter.java:96) at org.springframework.remoting.httpinvoker.HttpInvokerServiceExporter.handleRequest(HttpInvokerServiceExporter.java:73) at org.springframework.web.servlet.mvc.HttpRequestHandlerAdapter.handle(HttpRequestHandlerAdapter.java:49) at org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:875) at org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:809) at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:571) at org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:501) at javax.servlet.http.HttpServlet.service(HttpServlet.java:707) at javax.servlet.http.HttpServlet.service(HttpServlet.java:820) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:175) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:128) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:286) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:844) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447) at java.lang.Thread.run(Thread.java:619)
I am wondering, because before that, I was using the Hessianprotocol and everything was working fine - except the problem with large objects, which is the reason I want to switch to the httpinvoker.
I only switched the ServiceExporter and ProxyFactoryBeans from the Hessian Versions to the httpinvokers.
Maybe anybody knows this error and can help me.
best regards,
christian
*edit*
I found, that if I try to access the service from my Service-Import-Application, I do not get a EOF Exception, but a ClassNotFoundException in the Serverlog.
That's surprising, because the Class exists and is reachable (Remembering the hessian Version is running without that problem). Mybe that gives someone a hint.
