Exceptions in Sending SOAP Attachments

[Li Bing]

Dear Mark and all,   Sorry to bother you again! I don't know why I got stuck again whwen tring to run the sample of SOAP Attachment. Do you have the book, Professional Java Web Services? I am now following the book to learn Web Services.   In the part of Axis, it says it is possible to send a SOAP message with attachments. Similar to past experiences, I didn't find any configurations errors exited on my system. But it doesn't work. The exception is as follows,   [libing@enpc1932 SOAPAttachments]$ run.sh java.lang.NullPointerException  at org.apache.axis.encoding.JAFDataHandlerSerializer.serialize(JAFDataHandlerSerializer.java:87)  at org.apache.axis.encoding.TypeMappingRegistry.serialize(TypeMappingRegistry.java:275)  at org.apache.axis.encoding.SerializationContext.serialize(SerializationContext.java:417)  at org.apache.axis.encoding.SerializationContext.outputMultiRefs(SerializationContext.java:442)  at org.apache.axis.message.SOAPEnvelope.outputImpl(SOAPEnvelope.java:357)  at org.apache.axis.message.MessageElement.output(MessageElement.java:448)  at org.apache.axis.SOAPPart.getAsString(SOAPPart.java:329)  at org.apache.axis.SOAPPart.getAsBytes(SOAPPart.java:272)  at org.apache.axis.Message.getContentLength(Message.java:293)  at org.apache.axis.transport.http.HTTPSender.invoke(HTTPSender.java:354)  at org.apache.axis.SimpleTargetedChain.invoke(SimpleTargetedChain.java:104)  at org.apache.axis.client.AxisClient.invoke(AxisClient.java:178)  at org.apache.axis.client.Call.invoke(Call.java:1254)  at org.apache.axis.client.Call.invoke(Call.java:1113)  at org.apache.axis.client.Call.invoke(Call.java:1043)  at org.apache.axis.client.Call.invoke(Call.java:676)  at AxisClient3.main(AxisClient3.java:43) Can't convert 3 to Bytes java.lang.NullPointerException [libing@enpc1932 SOAPAttachments]$   The service code, client code, deploy.wsdd and attachment (user.properties) are attached.   Thanks so much for your help!
