Hi,
I'm writing an RCP app.
I need a fairly good Text editor, so I'm trying to included OOWriter in a frame and pack that into an EditorPart.

I have a wrapper for OOWriter that is (for now) fairly simple and works as expected using the include main().

package it.condarelli.swt.ooo;

import java.awt.BorderLayout;
import java.awt.Frame;
import java.awt.Panel;

import javax.swing.JPanel;
import javax.swing.JRootPane;

import org.eclipse.swt.SWT;
import org.eclipse.swt.awt.SWT_AWT;
import org.eclipse.swt.events.DisposeEvent;
import org.eclipse.swt.events.DisposeListener;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;

import com.sun.star.comp.beans.NoConnectionException;
import com.sun.star.comp.beans.OOoBean;
import com.sun.star.comp.beans.SystemWindowException;
import com.sun.star.frame.XDesktop;
import com.sun.star.io.IOException;
import com.sun.star.lang.IllegalArgumentException;
import com.sun.star.util.CloseVetoException;

public class OOoEditor extends Composite {

	public final String SWRITER = "private:factory/swriter";

	private static final long serialVersionUID = -1408623115735065822L;

	private OOoBean aBean;

	public OOoEditor(Composite parent, int style) {
		super(parent, style | SWT.NO_BACKGROUND | SWT.EMBEDDED);

		try {
			System.setProperty("sun.awt.noerasebackground", "true");
		} catch (NoSuchMethodError error) {
		}

		/* Create and setting up frame */
		Frame frame = SWT_AWT.new_Frame(this);
		Panel panel = new Panel(new BorderLayout()) {
			private static final long serialVersionUID = -5464002272885975878L;

			public void update(java.awt.Graphics g) {
				paint(g);
			}
		};
		frame.add(panel);
		JRootPane root = new JRootPane();
		panel.add(root);
		java.awt.Container contentPane = root.getContentPane();

		JPanel p = new JPanel();
		aBean = new OOoBean();
		p.setLayout(new java.awt.BorderLayout());
		p.add(aBean, java.awt.BorderLayout.CENTER);
		contentPane.add(p);
	}

	public void setDocument(String url) throws IllegalArgumentException,
			CloseVetoException, NoConnectionException, IOException,
			SystemWindowException {
		try {
			aBean.loadFromURL(url, null);
//			try {
//				XPropertySet ps = (XPropertySet) UnoRuntime.queryInterface(XPropertySet.class, aBean.getFrame());
//				try {
//					XLayoutManager lm = (XLayoutManager) UnoRuntime.queryInterface(XLayoutManager.class, ps.getPropertyValue("LayoutManager"));
////					lm.hideElement("private:resource/menubar/menubar");
//					lm.showElement("private:resource/menubar/menubar");
//				} catch (UnknownPropertyException e) {
//					e.printStackTrace();
//				} catch (WrappedTargetException e) {
//					e.printStackTrace();
//				}
//			} catch (NoConnectionException e) {
//				e.printStackTrace();
//			}

		} catch (IllegalArgumentException e) {
			e.printStackTrace();
		} catch (java.io.IOException e) {
			e.printStackTrace();
		}
		aBean.aquireSystemWindow();
	}

	/**
	 * closes the bean viewer and tries to terminate OOo.
	 */
	public void terminate() throws NoConnectionException {
		setVisible(false);
		XDesktop xDesktop = null;
		xDesktop = aBean.getOOoDesktop();
		aBean.stopOOoConnection();
		if (xDesktop != null)
			xDesktop.terminate();
	}

	/**
	 * closes the bean viewer, leaves OOo running.
	 */
	public void close() {
		setVisible(false);
		aBean.stopOOoConnection();
	}

	private static final String OFFICE_DOCUMENT = "file:///C:/Users/mauro/Downloads/TeX/Libro/yWriter/RTF5/RTF_00007.rtf";

	private static final String NEW_WRITER_DOCUMENT = "private:factory/swriter";

	public static void main(String[] args) {
		boolean empty = false;

		final Display display = new Display();
		final Shell shell = new Shell(display);
		shell.setLayout(new FillLayout());
		shell.setSize(900, 800);
		final OOoEditor viewer = new OOoEditor(shell, SWT.NONE);

		try {
			if (empty) {
				viewer.setDocument(NEW_WRITER_DOCUMENT);
			} else {
				viewer.setDocument(OFFICE_DOCUMENT);
			}
		} catch (Exception e) {
			e.printStackTrace();
		}

		shell.open();
		shell.addDisposeListener(new DisposeListener() {

			public void widgetDisposed(DisposeEvent e) {
				try {
					viewer.close();
				} catch (RuntimeException exception) {
					exception.printStackTrace();
				}
			}

		});
		while (!shell.isDisposed()) {
			if (!display.readAndDispatch())
				display.sleep();
		}
		display.dispose();
	}

}

Unfortunately when I try to use it in an EditorPart I get a runtime error.

I'm trying to use like this:

	@Override
	public void createPartControl(Composite parent) {
		GridData gridData = new GridData();
		gridData.horizontalAlignment = GridData.FILL;
		gridData.grabExcessHorizontalSpace = true;
		gridData.grabExcessVerticalSpace = true;
		gridData.verticalAlignment = GridData.FILL;
		top = new Composite(parent, SWT.NONE);
		top.setLayout(new GridLayout());
		oooE = new OOoEditor(top, SWT.NONE);
		oooE.setLayoutData(gridData);
	}

but it bombs out at the oooE = new OOoEditor(top, SWT.NONE); line with error:

Apparently it is unable to find the

import com.sun.star.comp.beans.OOoBean;

in OOoEditor.java that is obviousli found ok when running the frame standalone.
I tried several configurations, including copying all required libs into the workspace.

I think it's obvious I do not understand how to set-up Referenced Libraries for RCP.

I have no problem uploading the whole project, if that's useful.

Can someone help me?

To write a plugin your classpath has to be entirely described by your MANIFEST.MF.

That means the jars providing have to be included in your plugin (and on the bundle classpath) or have to be turned into bundles themselves (and required from your bundle).

There should be more info in http://wiki.eclipse.org/PDE on how to include 3rd party jars in a plugin.

Hi,

this explains how to convert jars into plugins:

Hope this helps, Lars

Many thanks.
Now I'm almost there.
Problem is OOo interaction needs some native libs (.dll under win and .so under linux) How can (should) I include them in the plugin?
Lars's tutorial covers only the pure java part.
I saw no obvious extensions.

If you include the DLLs (or .so for different platforms) in your bundle, then use Bundle-NativeCode to describe how to find them.
