web service error

Key: AXIS-2678

Project: Axis
Issue Type: Wish
Environment: WebSphere 5.1
Reporter: Lou Cunningham
Priority: Blocker
Hi,
I have wrote a Java web service that to be used by a .Net application where I
work. I am using a vendor java api to query and display statements in a pdf
file. I have to use the vendor api because our data repository is not a
database, but is a heirarchial vsam nodes. This repository resides on a
mainframe and is designed by the same vendor that created the api I am using. I
have tested the Java code for the service locally via JUnit test and everything
works.
I used Eclipse's web service generator to create the wsdl,
server-config.wsdd, deploy.wsdd and the undeploy.wsdd files. When I use the web
service generator I get the warning message below:
The service class "com.here.viewdirect.service.StatementService" does not
comply to one or more requirements of the JAX-RPC 1.1 specification, and may
not deploy or function correctly.
The field or property "keyValue" on the value type
"com.mobius.vdrapi.PageFactoryNode" used via the service class
"com.here.viewdirect.service.StatementService" has a data type,
"java.lang.Object", that is not supported by the JAX-RPC 1.1 specification.
Instances of the type may not serialize or deserialize correctly. Loss of data
or complete failure of the Web service may result.
The field or property "keyValue" on the value type "com.mobius.vdrapi.INode"
used via the service class "com.here.viewdirect.service.StatementService" has a
data type, "java.lang.Object", that is not supported by the JAX-RPC 1.1
specification. Instances of the type may not serialize or deserialize
correctly. Loss of data or complete failure of the Web service may result.
The field or property "topicFirstPageData" on the value type
"com.mobius.vdrapi.TopicSectionNode" used via the service class
"com.here.viewdirect.service.StatementService" has a data type,
"java.io.ByteArrayOutputStream", that is not supported by the JAX-RPC 1.1
specification. Instances of the type may not serialize or deserialize
correctly. Loss of data or complete failure of the Web service may result.
The field or property "keyValue" on the value type
"com.mobius.vdrapi.ListFactoryNode" used via the service class
"com.here.viewdirect.service.StatementService" has a data type,
"java.lang.Object", that is not supported by the JAX-RPC 1.1 specification.
Instances of the type may not serialize or deserialize correctly. Loss of data
or complete failure of the Web service may result.
The method "getStatement" on the service class
"com.here.viewdirect.service.StatementService" uses a data type,
"java.io.ByteArrayOutputStream", that is not supported by the JAX-RPC
specification. Instances of the type may not serialize or deserialize
correctly. Loss of data or complete failure of the Web service may result.
The value type "com.mobius.vdrapi.ReportPageNode" used via the service class
"com.here.viewdirect.service.StatementService" does not have a public default
constructor. Chapter 5.4 of the JAX-RPC 1.1 specification requires a value type
to have a public default constructor, otherwise a JAX-RPC 1.1 compliant Web
service engine may be unable to construct an instance of the value type during
deserialization.
The value type "com.mobius.vdrapi.NodeType" used via the service class
"com.here.viewdirect.service.StatementService" does not have a public default
constructor. Chapter 5.4 of the JAX-RPC 1.1 specification requires a value type
to have a public default constructor, otherwise a JAX-RPC 1.1 compliant Web
service engine may be unable to construct an instance of the value type during
deserialization.
The value type "com.mobius.vdrapi.IListFactory" used via the service class
"com.here.viewdirect.service.StatementService" does not have a public default
constructor. Chapter 5.4 of the JAX-RPC 1.1 specification requires a value type
to have a public default constructor, otherwise a JAX-RPC 1.1 compliant Web
service engine may be unable to construct an instance of the value type during
deserialization.
The value type "com.mobius.vdrapi.TopicSectionNode" used via the service
class "com.here.viewdirect.service.StatementService" does not have a public
default constructor. Chapter 5.4 of the JAX-RPC 1.1 specification requires a
value type to have a public default constructor, otherwise a JAX-RPC 1.1

service engine may be unable to construct an instance of the value type during
deserialization.
I crossed my fingers and clicked the OK button. I deployed the service on a
WebSpher server. I next created a client using wsdl2java. I tested the service
using a simple test method that takes and returns a String. It worked for that,
but when I try to use the vendor api I get the error message:
Caused by: org.xml.sax.SAXParseException: Premature end of file.
at org.apache.xerces.parsers.AbstractSAXParser.parse(Unknown Source)
at javax.xml.parsers.SAXParser.parse(SAXParser.java:345)
at
org.apache.axis.encoding.DeserializationContext.parse(DeserializationContext.java:227)
at org.apache.axis.SOAPPart.getAsSOAPEnvelope(SOAPPart.java:696)
... 15 more
Is there any hope, or I am just hosed because of the vendor api?
