Java ArcMap-Addin: Show html page with JEditorPane

TomSchuller

Hy,
I'm working on a Java Tool-addin.

The tools should show up an html page.
I tried out with the JEditorPane.

The JEditorPane is working fine while running as single Java application. When the same code is integrated in a Tool-Addin to be executed in ArcMAP, I'm getting an exception.

Is there a way to use the JEditorPane in ArcMAP or an other possibility to display a html page in ArcMAP?

You find my JEditorPane code and the exception below.

Thanks,
Tom
 

JEditorPane editorPane = new JEditorPane("http://www.google.com");
editorPane.setEditable(false);
JScrollPane scollPane = new JScrollPane(editorPane);
JOptionPane.showMessageDialog(null,scollPane);

Tom,

Can you please try the below code in the mousePressed method of the tool and see if it is working.

// Called when a mouse tool is pressed while the tool is active
@Override
public void mousePressed(MouseEvent me) {
     Runnable openEditorPane = new Runnable() {
         public void run() {
         Thread.currentThread().setContextClassLoader(ClassLoader.getSystemClassLoader());
         JEditorPane editorPane = null;       
      try {
       editorPane = new JEditorPane("http://www.google.com");
      } catch (IOException e) {
       e.printStackTrace();
      }
      editorPane.setEditable(false);
      JScrollPane scollPane = new JScrollPane(editorPane);
      JOptionPane.showMessageDialog(null,scollPane);       
       }
     };
    SwingUtilities.invokeLater(openEditorPane);
}
