[Htmlunit-user] First obstacles, javascript exception for MRBS.

[<rg...@gm...>]

Dear list users,

the reason for joining this list is as follows:
I am looking to fill in numerous bookings into our
meeting room booking system (mrbs) that is hosted
externally (otherwise it was easier to extend native
php scripts). Those bookings are derived from our
schedule, saved in a csv file.

As I am a bit familiar with Java, I am confident to
accomplish this mission by means of htmlunit.

>From within Debian testing, I use these packages:

libjenkins-htmlunit-java:
  Installed: 2.6-jenkins-6-1
libhtmlunit-java:
  Installed: 2.8-1
libjenkins-htmlunit-core-js-java:
  Installed: 2.6-hudson-1-1

passing these jar libraries to the javac compiler:

/usr/share/junit-3.8.3.jar -- for assertions
/usr/share/htmlunit-2.8.jar -- for WebSite and other classes.

After importing needed classes (not stated on the "get started"
section) like this:

import  com.gargoylesoftware.htmlunit.*;
import com.gargoylesoftware.htmlunit.html.HtmlPage;
import com.gargoylesoftware.htmlunit.BrowserVersion;
import org.junit.Assert;

the first example tests work as they should. However, when
I just try to open the login page of our mrbs, I get nasty
js errors, and I wonder ...

- did I do any general mistakes?
- did I use wrong libraries?
- did anybody alread succeed with mrbs ?
- why is the constant BrowserVersion.FIREFOX_17 reported to be unknown?


public void mrbsPage() throws Exception {
    final WebClient webClient = new WebClient(BrowserVersion.getDefault());
    final HtmlPage page =
webClient.getPage("http://mrbs.HIDDEN.URL/admin.php");
...}

The output of console is quoted below.

Thanks very much for any hints.
Kind regards
Ralf

test11.mrbsPage();
