Just tried the Web Service Client Example posted on 8th jan 2007 at http://www.myeclipseide.com/images/tutorials/demos/terra_server_client/tutorial.html and followed all three flash demos but got an exception. Turns out that my version of myeclipse (20061111-5.1.0-GA) did not add the XFire 1.2 HTTP Client Libraries by default.

To fix this you need to right click on project name, select Build Path->Add Libraries. Select “Myeclipse Libraries” from the Add Library window and click next. scroll down the list until you find Xfire 1.2 HTTP Client Libraries, check the box and then click finish.

Don;t forget to add the import statements for the service objects you want to use in the client program as well.

Great catch, I just confirmed this is fixed in 5.5. Sorry for the confusion.

Hi,

I have used the Web Service Client Tutorial as the basis of a couple of projects without any problems so far. However, I just tried to generate some client classes using the following WSDL and I get an internal error during “Generate Client”. I cannot get XFire to generate the service classes. I am using Version: 5.1.0 Build id: 20061111-5.1.0-GA Any ideas?

Many Thanks,

Andy.

Andy,

If you open the WSDL file in our WSDL editor and validate it, you’ll see that there’s an error with the “BaseResponse” component.

Here’s the error I see.

src-resolve.4.1: Error resolving component ‘BaseResponse’. It was detected that ‘BaseResponse’ has no namespace, but components with no target namespace are not referenceable from schema document ‘API.wsdl’. If ‘BaseResponse’ is intended to have a namespace, perhaps a prefix needs to be provided. If it is intended that ‘BaseResponse’ has no namespace, then an ‘import’ without a “namespace” attribute should be added to ‘API.wsdl’.

If you correct that, the generation should work fine.

This is very nitpicky, but the tutorial has a few it’s/its mistakes:

After our project has been created the next thing we need to do is let MyEclipse generate our web service client for us. In this step we are having MyEclipse connect to the web service, retrieve it’s WSDL and then in our project, generate all the classes and stubs required to…

This occurs elsewhere in the tutorial too. Spellcheckers are no one’s friend.

I have just installed “MyEclipse_5.1.1GA_Installer.exe”
on My Windows XP Eclipse 3.2.2 .
My web service is on another url with the https url:
https://192.168.43.64:18443/MTT_CC/services/ManagerCaller?wsdl

when i try to create a web service client by applying the rules defined here http://www.myeclipseide.com/images/tutorials/demos/terra_server_client/tutorial.html

i viewed the error message from
Help–>About My Eclipse Enterprise Workbench–>Configuration Details–>View Error Log–>

why couldn’t i generate web service client?

i am using C:\Program Files\Java\jdk1.5.0_07.
And i signed the ceritificate by calling:

C:\Program Files\Java\jdk1.5.0_07\bin>

Where is my problem?

The exception seems pretty straight forward… the client generation wizard doesn’t like running through your proxy for some reason. Can you host the service locally and generate the client by pointing it at localhost instead?

I am having difficulty understanding how proxies work with XFire. I tried the TerraServiceClient from the example and was not at all surprised to get the error:

SEVERE: java.net.ConnectException: Connection timed out: connect

I had to download the WSDL file an put it locally to generate the classes. I would have to provide my proxy information somehow before I would expect to be able to access the WSDL url from Java code or connect to the service, no?

I would like to create a client that will invoke a service via a WSDL (no prior knowledge about the service implementation class), use a proxy, and use authentication. Haven’t found an example that puts these together, or even two together…

Good afternoon! I just ran through the webservices client example (http://www.myeclipseide.com/images/tutorials/demos/terra_server_client/tutorial.html) with MyEclipse 5.5 and there is a problem in the pasted code (last step in Step 4) that I can’t seem to resolve.

In order to get the example most of the way home, I had to fully qualify several classes from the WSDL (see below), but the MyEclipse complains about the “terraServiceSoap” object reference in the following line:

com.terraservice_usa.LonLatPt result = terraServiceSoap.convertPlaceToLonLatPt(place);

It looks like changing “terraServiceSoap” to service (the actual TerraServiceSoap object in the source) fixes the problem.

Chris,
Thanks for the heads up, I’ll need to make a note of it and go back through that demo and see what needs to be updated.
