Error consuming a webservice

[Michael Hnat]

Hi,

after all the Lucee posts about filextensions, etc. I have a coding question :-)

I'm trying to connect to the cleverreach API, but I stuck in the first line of code.

ws = CreateObject("webservice", 'http://api.cleverreach.com/soap/interface_v5.1.php?wsdl');

results in the following error, and I have no clue what it is:

Lucee 4.5.0.042 Error (java.io.IOException)
Message	Type {http://schemas.xmlsoap.org/wsdl/}string is referenced but not defined.
Cause	java.io.IOException

Stacktrace:

Happy about any idea or hint.

Thanks,

I’m assuming that’s not an issue with Lucee, but the provided WSDL looks as if it could be the issue.

The error message tells your that the WSDL parser is looking for an element string in the namespace http://schemas.xmlsoap.org/wsdl and can’t find it.

As far as I can see, all string references are properly namespaced with xsd: but this one:

<xsd:attribute ref="SOAP-ENC:arrayType" wsdl:arrayType="string[]”/>

In the WSDL spec there is a wsdl:arrayType, nevertheless I would think the string[] should be xsd:string[] though and it seems to me with the string[] not being namespaced, Axis would try to interpret it as part of the WSDL namespace (and spec).

Cheers

Kai

Thanks for the hint.
I got in contact with the guys of Cleverreach and there is no problem when using the latest wsdl2java 1.6.2 and even the Apache CXF 3.0.3.
The Problem seems to be the axis version used in Railo/Lucee which is dated as:
Name: org/apache/axis
Implementation-Title: Apache Axis
Implementation-Version: 1.4 1855 April 22 2006
Implementation-Vendor: Apache Web Services


Is there a way to replace it with the current version? I read, that it's not easy to do this, but currently I'm screwed, since I'm not able to communicate with cleverreach. Am I the only one who has to communicate with cleverreach?

Still, any help welcome.

According to Axis website, 1.4 dated April 22, 2006 is the latest version.
https://axis.apache.org/axis/

[Michael Hnat]

It is for Axis 1.
But the service I have to consume requires Axis 2, which is currently version 1.6.2, dated April 2012

Trying this with the latest Axis2 1.6.2 works fine:
'./bin/wsdl2java.sh -uri "http://api.cleverreach.com/soap/interface_v5.1.php?wsdl&literal=true"';


still screwed,
Michi

Hi,

not screwed anymore :-)
Kai, thanks. It was exactly what you mentioned and cleverreach changed it to make their API Axis 1.4 compatible.

Thanks,
Michi

Axis 2 is a _very_ different implementation of Webservices than Axis 1 is. From experience working with both, it’s not a trivial thing to just “switch” it in Railo.

A suggestion I can make is to write (or get you someone to write you) a Java proxy using Axis 2 that handles the communication with your service that runs on some port on your server and Railo communicating with the endpoint on that port. I’ve had to do similar with ACF that only supported Axis 1 until version 9 or so and I needed to communicate with certain WS-* endpoints.

Cheers

Oh, cool! So, ignore my alternative suggestion from the previous mail then :)
