Hi,

I am using Scout Juno SR1. Its the first time I am generating a WebService Consumer.

When I create a webservice Consumer (using the tutorial on that topic: http://wiki.eclipse.org/Scout/Tutorial/3.8/webservices/Webservices_with_JAX-WS) I get an error as soon as I finish the wizard. I think all the files are generated but the service and Port type are not filled (see Attachment below). I get an Error on my source but I don't know how to fix it.

Console code

[INFO] JAX-WS option: -b WEB-INF/build/StockQuoteServiceSoapWebServiceClient-bindings.xml
[INFO] JAX-WS directive: -verbose

How can I configure or fix this?

Can you try it with a Juno SR2?
I remembered forum threads here mentioning problem with some versions of Scout SDK (but I do not remember which ones).

Hi Yassine

The problem is based on that the Java Compiler cannot be found in order to compile your JAX-WS artifacts. That is why your 'service' and 'port type' is still empty after generating the web-service stub because not being generated at all. If you have a look at your console output, you may notice the NullPointerException indicating exactly this problem.

To solve the issue, please ensure the default installed JRE on your eclipse platform to point to a valid JDK location (and not only JRE). You can verify and change your settings via Eclipse menu 'Windows | Preferences | Java | Installed JREs'. Please have a look at the attached screenshot to have an idea about what I mean.
Generally, if not being found, the compiler is tried to be located by evaluating your system variable 'JAVA_HOME'. Also, it is good practice to point it not only to a JRE but a JDK location instead.

Please let me know if this solved your problem.

@Jeremie: I tried with both, Juno SR1 and SR2, respectively and both are working as expected.

Thank you Mr. Daniel.
It works now.
I pointed to JDK location instead of JRE as you said.
Thanks Mr. Jeremie for being interested in this topic.
Regards,
Yassine
