Jakarta Tomcat 4.1.12 Java Web Service, .NET client

[Sandra]

Hi,

How can I access a Web Service made in Java using Jakarta Tomcat 4.1.12 -
Axis 1.0 from a client in Visual Studio .NET (using a Visual Basic.NET Web
Application)?

I have an autogenerated WSDL file frm Tomcat.

When I use Add Web Reference from VS.NET the Reference is linked to my application
but the Jakarta Tomcat server gives messages indicating wrong types even
though I didn't write any code.

Then if I try to add code, the Intellisense doesn't show this class between
the possibilities. I think that this means that the class is not considered.

How can resolve this?

Thank in advance,
Sandra

VS.NET generates a proxy class from the WSDL that you specify. You can find
the file in the Web References directory (under wwwroot\$ProjectDir). Examining
the file could offer you clues to solve the problem.

Not exactly: it could be a problem of namespaces; usually, you access the
proxy class by specifying NameSpace.ClassName. Don't worry about Intellisense,
sometimes it doesn't simplify things.

Make sure that you instantiate correctly the proxy class and invoke the web
method with the appropriate parameters.

Good luck,

I have the same problem. It seams like i cant deserialize the xml.
I'm using the same xml namespaces in the client as in the host.

The company that delivers the host says that they have no problem using the
ws from Java.
Is this a .NET problem or have I done something wrong?

It probably depends on <types> section of your WSDL. I also have the same
problem with the following description where there is nested <complexType>
with no name:
<complexType name="RecMap">
<sequence>
<element maxOccurs="unbounded" minOccurs="0" name="item">
<complexType >
<sequence>
<element name="key" type="xsd:string"/>
<element name="value" type="xsd:string"/>
</sequence>
</complexType >
</element>
</sequence>
</complexType>
In fact Visual Studio isn't able to create proxy for this data. But it creates
proxy for the following data:
<complexType name="RecMap">
<sequence>
<element maxOccurs="unbounded" minOccurs="0" name="item"
type="tns2:RecItem" />
</sequence>
</complexType>
<complexType name="RecItem">
<all>
<element name="key" type="xsd:string"/>
<element name="value" type="xsd:string"/>
</all>
</complexType>
However I cannot use the second WSDL because it doesn't respect SOAP message
format of my java web service.
Any suggestion?

You should try to give a name to the second (nested) complex type. I think
that would solve the problem.

As an example, .NET handles this by the use of attributes. You declare a
class which has a vector field; in this case, you bind that field with the
following attribute:

[XmlArrayItem(__typeof(ClassItem), IsNullable=true)]

which tells to generate appropriate descriptions for vector's items (i.e.
description for the class ClassItem)

Try to do something simmilar with Axis!

Hi,
I managed to call Tomcat Axis from .NET by making sure that the first line
of the wsdl was NOT
<?xml version=\"1.0\" encoding=\"utf-8\"?>

Strangely, that type of line was not authorized in WSDL by my version of
.NET !
