Using of DataHandler

[Ferruh Zamangoer]

Hi,   I’am trying to use a Data Handler to send a serialized object to my server. On the Client Side I try to serialize my object:   Client Side:   //Gets the CContentService         CContentServiceServiceLocator csLocator =             new CContentServiceServiceLocator();         csLocator.setEndpointAddress(new QName("CContentService"), "http://localhost:8080/axis/services/CContentService");         CContentService csService               =             csLocator.getCContentService();                 ContentInfo contentInfo = new ContentInfo("sf_helmi",1111, false, null, "wav");                 ContentIDCalculator cIDCalculator = new ContentIDCalculatorImpl();         String absolPath = "F:"+File.separator+"Temp"+File.separator+"Upload"+File.separator+"sf_helmi.wav";         ContentID contentID = cIDCalculator.calculateContentID(contentInfo,absolPath);                 ByteArrayOutputStream baos = new ByteArrayOutputStream();         ObjectOutputStream oos = new ObjectOutputStream(baos);         oos.writeObject(contentID);         oos.flush();                 //Test CContentExchangeValidatorService         DataHandler dhSource = new DataHandler(baos, "application/x-java-serialized-object");           DataHandler dh  = csService.addContent("poseidon", "tigris", dhSource);                oos.close();         baos.close();           Server Side     //The content is extracted from the dataHandler object.         BufferedInputStream bis =                         new BufferedInputStream(                             handler.getDataSource().getInputStream());                                               ObjectInputStream ois = new ObjectInputStream(bis);                     ContentID contentID   = (ContentID)ois.readObject();   Error:     50002 [http-8080-Processor5] FATAL org.apache.axis.Message  - InvocationTargetException:  java.lang.reflect.InvocationTargetException             at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)             at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:39)             at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:27)             at java.lang.reflect.Constructor.newInstance(Constructor.java:494)             at org.apache.axis.Message.setup(Message.java:341)             at org.apache.axis.Message.<init>(Message.java:232)             at org.apache.axis.transport.http.AxisServlet.doPost(AxisServlet.java:628)             at javax.servlet.http.HttpServlet.service(HttpServlet.java:716)             at org.apache.axis.transport.http.AxisServletBase.service(AxisServletBase.java:327)             at javax.servlet.http.HttpServlet.service(HttpServlet.java:809)             at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:200)             at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:146)             at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:209)             at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(StandardPipeline.java:596)             at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:433)             at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:948)             at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:144)             at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(StandardPipeline.java:596)             at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:433)             at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:948)             at org.apache.catalina.core.StandardContext.invoke(StandardContext.java:2358)             at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:133)             at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(StandardPipeline.java:596)             at org.apache.catalina.valves.ErrorDispatcherValve.invoke(ErrorDispatcherValve.java:118)             at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(StandardPipeline.java:594)             at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:116)             at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(StandardPipeline.java:594)             at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:433)             at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:948)             at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:127)             at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(StandardPipeline.java:596)             at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:433)             at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:948)             at org.apache.coyote.tomcat4.CoyoteAdapter.service(CoyoteAdapter.java:152)             at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:799)             at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.processConnection(Http11Protocol.java:705)             at org.apache.tomcat.util.net.TcpWorkerThread.runIt(PoolTcpEndpoint.java:577)             at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:683)             at java.lang.Thread.run(Thread.java:595) Caused by: Error reading data stream:  Error in input stream;
