[wtp-dev] Opening the internal browser in Eclipse

[buddhika chamith <chamibuddhika@xxxxxxxxx>]

Hi,

I wanted to open the internal web browser to display an SVG file in my plugin. I used the following code snippet in browser invocation logic.

 IWorkbenchBrowserSupport browserSupport = PluginActivator.getDefault().getWorkbench().getBrowserSupport();
 IWebBrowser browser = browserSupport.createBrowser(IWorkbenchBrowserSupport.LOCATION_BAR, null,"Test", "Test");
 URL url = "" URL("the file url address");
 browser.openURL(url);

But it failed with the following exception .

org.eclipse.ui.PartInitException: Could not open a Web browser because there are none configured. Check the Web Browser preferences.
    at org.eclipse.ui.internal.browser.DefaultBrowserSupport.createBrowser(DefaultBrowserSupport.java:108)
    at org.eclipse.ui.internal.browser.WorkbenchBrowserSupport.createBrowser(WorkbenchBrowserSupport.java:97)

So I tried to change the preference using Window-> Preference->General->Web browser in the eclipse application. But strangely the option to select the internal browser was grayed out.

 Then the next time I re-runned the eclipse application. Here I was able to  change the browser setting to use the internal browser(by default it had been selected to use the external browser) before invoking my plugin. Then again I tried to run my plugin.

Then I got the following NullPointer exception.

java.lang.NullPointerException

    at org.eclipse.ui.internal.browser.DefaultBrowserSupport.createBrowser(DefaultBrowserSupport.java:137)
    at org.eclipse.ui.internal.browser.WorkbenchBrowserSupport.createBrowser(WorkbenchBrowserSupport.java:97)

Have anyone got this kind of problem before? How can I get this to work? I'm working in Eclipse Ganymede in Ubunutu.
