Dashboards - WSDL URL

Dear experts,

I want to create a dashboard that has capability to insert and update database. I use the link below as reference:

Using Xcelsius and Webservices to insert comments into a database | David Lai's Business Intelligence Blog

Then I created a simple java web service in Netbeans 8, run it independently, and it works fine.

Unfortunately, when I put the WSDL URL for BIWS Connection in SAP Dashboards, it gives error "Unable to load URL".

I have tried to check the WSDL URL in browser, it successfully shows the code (not Page 404).

After that, I did further research, and I found this link about "Top 10 Guideline for Creating Web Service in Xcelsius":

http://www.femkekooij.nl/?p=933

In that link, it shows the WSDL URL that worked in xcelsius (I tried it myself, and it really can be loaded), here is the WSDL URL:

http://services.aonaware.com/DictService/DictService.asmx?WSDL

The code is a bit different from mine (which is auto-generated by Netbeans 8). Mine is like the attachment below (I paste it here too for convenience).

What should I do to resolve this?

Thank you.
