Why does Axis2 throw "An invalid request URI was provided" when connecting to an .asmx SOAP endpoint?

Question

I am using Axis2 to consume a SOAP web service hosted at an endpoint that looks like this: https://example.com/car.asmx?wsdl

However, when I make a request, I get the following error:

An invalid request URI was provided. Either the request URI must be an absolute URI or BaseAddress must be set.

org.apache.axis2.AxisFault: An invalid request URI was provided. Either the request URI must be an absolute URI or BaseAddress must be set.

Some details of my client:

I generated the client stub from the WSDL file using axis2-wsdl2code-maven-plugin for java 8.

MyGeneratedStubfromWSDL myStub = new MyGeneratedStubfromWSDL(
configurationContext, endpointURl);

I suspect that the issue might be related to the .asmx endpoint or a misconfiguration in Axis2.

What I've Tried:

• Verified that the endpoint URL is correct.
• Tested the endpoint using Postman and SoapUi, which works fine.
• Checked the WSDL for any inconsistencies.
• Explicitly set the SOAPAction header in my Axis2 client code:

stub._getServiceClient().getOptions().setAction("SOAPActionFromWSDL");

• I also did try and error with some options and HTTP Header

serviceClient.getOptions().setTo(new EndpointReference(endpointUrl)); serviceClient.setTargetEPR(new EndpointReference(endpointUrl)); serviceClient.getOptions().setProperty("transport.http.URL", endpointUrl); serviceClient.getOptions().setProperty("BaseAddress", "https://example.com"); serviceClient.getOptions().setAction("http://example/services/example/service"); serviceClient.getServiceContext().setProperty("transport.http.address", endpointUrl); serviceClient.getServiceContext().setProperty("endpoint.url", endpointUrl); serviceClient.getAxisService().addParameter("ServiceEndpoint", endpointUrl);

Questions:

• Is there any specific configuration required in Axis2 for .asmx endpoints?
• Could this error be related to Axis2 not handling .asmx services correctly? Or not compatible with Microsoft ASP.NET?
• Are there any known issues with Axis2 and SOAP 1.1 that might cause this error?

Any guidance or suggestions would be greatly appreciated!
