Hi All:
I am getting a NullPointerException when invoking a webservice using a JavaClient.
Service Interface is
public boolean uploadFile(
DataHandler dataHandler,
MetadataBean metadataBean,
FolderBean folderBean);
MetadataBean has a another bean (as a composite) PublicationMetaConf.
This is my wsdd file
<deployment xmlns="http://xml.apache.org/axis/wsdd/"
xmlns:java="http://xml.apache.org/axis/wsdd/providers/java"
xmlns:schema="http://www.w3.org/2001/XMLSchema"
xmlns:au="AutoUploaderService">
<service name="AutoUploaderService" provider="java:RPC">
<namespace>AutoUploaderService</namespace>
<parameter name="className" value="cat.vce.autoUpload.server.service.AutoUploaderServiceImpl"/>
<parameter name="allowedMethods" value="*"/>
<typeMapping deserializer="org.apache.axis.encoding.ser.JAFDataHandlerDeserializerFactory"
languageSpecificType="java:javax.activation.DataHandler" qname="au ataHandler"
serializer="org.apache.axis.encoding.ser.JAFDataHandlerSerializerFactory"
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
/>
<beanMapping qname="au ublicationMetaConf" languageSpecificType="java:cat.vce.autoUpload.server.conf.PublicationMetaConf"/>
<beanMapping qname="au:MetadataBean" languageSpecificType="java:cat.vce.autoUpload.server.bean.MetadataBean"/>
<beanMapping qname="au:FolderBean" languageSpecificType="java:cat.vce.autoUpload.server.bean.FolderBean"/>
</service>
</deployment>

I have two questions
1) When I make a call using Java client I am getting an NullPointerException
2) I am not able to generate Client side code using WSDL2Java. I am getting this error
[java] java.io.IOException: Type {AutoUploaderService}DataHandler is referenced but not defined
[java] at org.apache.axis.wsdl.symbolTable.SymbolTable.checkForUndefined(SymbolTable.java:522)
[java] at org.apache.axis.wsdl.symbolTable.SymbolTable.add(SymbolTable.java:422)
[java] at org.apache.axis.wsdl.symbolTable.SymbolTable.populate(SymbolTable.java:408)
[java] at org.apache.axis.wsdl.symbolTable.SymbolTable.populate(SymbolTable.java:393)
[java] at org.apache.axis.wsdl.gen.Parser$WSDLRunnable.run(Parser.java:245)
[java] at java.lang.Thread.run(Thread.java:536)
It would be great is someone could help me.
Rgds,

Well, I dunno about AXIS, but I think we need more information on:

1) When I make a call using Java client I am getting an NullPointerException


Is that thrown on the client side before it sends the SOAP request?
On the server side when it gets the request?
On the client side when it gets the response?
From your code or from AXIS classes?

Just a guess
Check whether you had included activation.jar in your lib folder or classpath.
