    <p>My plugin has to write to the eclipse console - for testing purpose I simplified my code, so that I only have the following:</p> <pre><code>public void start(BundleContext context) throws Exception { super.start(context); plugin = this; System.out.println("Tecomp Plugin is running"); MessageConsole myConsole = new MessageConsole("My Console", null); //myConsole.activate(); ConsolePlugin.getDefault().getConsoleManager().addConsoles(new IConsole[]{ myConsole }); ConsolePlugin.getDefault().getConsoleManager().showConsoleView(myConsole); final MessageConsoleStream stream = myConsole.newMessageStream(); stream.setActivateOnWrite(true); stream.println("Hi there!"); stream.close(); } </code></pre> <p>It's a simple plugin, the method start belogs to the class extending AbstractUIPlugin - it't no rcp application. Code works fine inside the runtime workbench - once the plugin is installed, the output gets lost somewhere. The rest of the plugin is working properly.</p> <p>Is there perhaps a problem with the ConsolePlugin? Or are streams handled differently in the runtime workbench and the development workbench?</p> <p>I tried both - a feature project and directly copying the plugin jar to the eclipse directory - for installing the plugin - same result for both...</p> <p>Any help is welcome, because I'm struggeling with that problem for a while now...</p> <p>Regards, Kathi</p> <h3>Edit:</h3> <p>it doesn't seem to be a problem of the Console... I provided my own view for printing the output, but although declard in the plugin.xml there is no view after installing the plugin... here is what I did: -export the plugin with the ExportWizard into a jar-archive -copied this archive to /usr/share/eclipse/plugins -restarted eclipse</p> <p>or with a feature project: -exported the feature-project containing my plugin with the ExportWizard -removed the above jar archive from the eclipse dir -installed the feature -restarted eclipse</p> <p>both didn't word - did I get something wrong with installing the plugin? The jar-archive is ok, I checked it - it's the latest version. But somehow it seems that eclipse is still working with some older plugin without the changes I made</p> <p>regards, Kathi</p> <h3>Edit:</h3> <p>I implemented the IStartup Interface end extended the org.eclipse.ui.startup point, but nothing changed... I really thinks it's an installation problem somehow. I commented out some output but it's still printed to the debug console. Is there some sort of plugin cache in eclipse? So that the new code doesn't get read?</p> <h3>Edit:</h3> <p>Thanks for the suggestions, but starting eclipse with the -clean option didn't help - I'll try to install the plugin in some other environment next week - perhaps there is something wrong with mine...</p> <h3>Edit:</h3> <p>the code in the class calling the compilier looks as follows:</p> <pre><code>private MessageConsole findConsole(String name){ ConsolePlugin plugin = ConsolePlugin.getDefault(); IConsoleManager conMan = plugin.getConsoleManager(); IConsole[] existing = conMan.getConsoles(); for (int i = 0; i&lt;existing.length; i++){ if (name.equals(existing[i].getName())){ return (MessageConsole)existing[i]; } } //no console found -&gt; create new one MessageConsole newConsole = new MessageConsole(name, null); conMan.addConsoles(new IConsole[]{newConsole}); return newConsole; } public void run() { MessageConsole console = findConsole("tecompConsole"); //display the tecomp Console IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage(); String id = IConsoleConstants.ID_CONSOLE_VIEW; try { IConsoleView view = (IConsoleView) page.showView(id); view.display(console); } catch (PartInitException e) { e.printStackTrace(); } MessageConsoleStream output = console.newMessageStream(); String tecompPath = TecompPlugin.getDefault().getPreferenceStore().getString(IEiffelConstants.TECOMP_PATH); if (checkTecompPath(tecompPath)){ String line; String[] cmd = {tecompPath, pathToAceFile}; try{ output.println("calling tecomp"); Process tecomp = Runtime.getRuntime().exec(cmd); //capture stdout und stderr from tecomp BufferedReader input = new BufferedReader( new InputStreamReader(tecomp.getInputStream())); BufferedReader err = new BufferedReader( new InputStreamReader(tecomp.getErrorStream())); while ((line = input.readLine()) != null ){ output.println(line); } input.close(); while ((line = err.readLine()) != null){ output.println(line); } err.close(); output.close(); tecomp.waitFor(); //System.out.println(tecomp.exitValue()); }catch (Exception err){ err.printStackTrace(); } } else { try{ output.println("please specify a tecomp path"); output.close(); }catch (Exception err){} } } </code></pre> <p>but the first test example should work, shouldn't it? I create a new MessageConsoleStream and write to it manually. Thats exactly like the examples I found.</p> <h3>Edit:</h3> <p>The code doesn't belog to an rcp application - it's just a plugin, extending the eclipse ide with support for the eiffel programming language. So I think your suggestion doesn't work for my plugin - VonC, at least I don't know where to put your code... My first sample code in the initial question gets called inside the Plugin class extending AbstractUIPlugin within the start(BundleContext context) method. My plugin in running, so somewhere this method gets called. And as I mentioned - plugin works fine inside the runtime workbench...</p> <p>I'm sorry if this is not the right place for an additional explanation of my question - but it seemed to be the only place the system allows me to post some further lines. Comments to your answers are not allowed for me, because I just signed in and for that I don't have enough reputation points... so, please correct me, if I'm using the system wrong :) thx</p>

    1. COThe Eclipse console has a list that is shown when a small triangle (pointing down) at the top left is clicked. Does your console appear there? I believe it should. If it is then select the console to see the contents that you are logging there.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
