HTTP connectivity error while using Blackberry MDS and JDE 5.0.0

761579

Hello,

I am using BB MDS simulator 4.1.2 and BB JDE 5.0.0 for testing sample Oracle ADF Mobile client apps that I have developed.
My app tries to access webservices via HTTP.

Here is where I am encountering a HTTP connectivity issue.

1. For instance, while trying to test HTTP using Blackberry browser, I see the error : "Unknown host mobile.blackberry.com:80"

2. The sample I tried to run to test webservices - accepts a word from the user and gets it translated in to a desired language, using a webservice provided on the internet.
Here, I have tried to translate the word 'madam' from English to French.
I have encountered a HTTP/1.0 400 Bad Request.

Kindly have a look at the MDS Trace as below (related entries in bold) and suggest if I am missing something from the configuration perspective.

PS : I have tried various options from the blackberry forums but they were not very helpful.

Hi, there:

A couple of things to try and check:

- Does your network connection goes through proxy server? If you are behind a proxy server, then you would need to set up proxy server in MDS by open the file <MDS simulator install>/config/rimpublic.property, go to the [HTTP Handler] section, and add the following line:

application.handler.http.proxyEnabled = true
application.handler.http.proxyHost=<your proxy server host name>
application.handler.http.proxyPort=<your proxy server port>

- Try BlackBerry MDS simulator that came with JDE 5.0. MDS 4.1.2 should still work with 5.0 device simulators, but it's worth a shot

Can you hit the web service from the browser in your Blackberry simulator? Feel free to directly contact me at [email protected] - if necessary we can also pull in BlackBerry/RIM resources to help diagnose this.

Thanks,

Joe Huang

Hi Joe,

As suggested, changing my proxy settings to www-proxy.us.oracle.com and port 80 did the trick! It worked!! :-)

Thanks a lot for your time!!
