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 = new 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

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.

Chamith Buddhika.
