[a2242]

Hi All,

I am new to this forum. In my application I came across a new requirement where I have to convert RTF files to Word and PDF formatted files.

I am searching for an API using which my java application can able to convert the above specified formats.

Please guide me in right direction? Any clue is also highly appreciated.

Its urgent.

Thanks in advance.

Hi, I am not a dev and the following is by no means light weight.
But maybe you can utilize OpenOffice and its UNO api to convert between any format OpenOffice can import and export.
api: Overview (Java UNO Runtime Reference)

Hi,

I tried with below code :

		
import com.sun.star.beans.PropertyValue;
import com.sun.star.beans.XPropertySet;
import com.sun.star.comp.helper.BootstrapException;
import com.sun.star.frame.XComponentLoader;
import com.sun.star.frame.XStorable;
import com.sun.star.lang.XComponent;
import com.sun.star.text.XParagraphCursor;
import com.sun.star.text.XText;
import com.sun.star.text.XTextDocument;
import com.sun.star.uno.Exception;
import com.sun.star.uno.UnoRuntime;
import com.sun.star.util.XCloseable;

public class Converter2 { 

	public static void main(String[] args)
	{
		try{
		// connect to open office
        	com.sun.star.uno.XComponentContext xContext;
			xContext = com.sun.star.comp.helper.Bootstrap.bootstrap();
        	com.sun.star.lang.XMultiComponentFactory xMCF = xContext.getServiceManager();
        	Object oDesktop = xMCF.createInstanceWithContext("com.sun.star.frame.Desktop", xContext);
        	XComponentLoader xCLoader = (com.sun.star.frame.XComponentLoader) UnoRuntime.queryInterface(com.sun.star.frame.XComponentLoader.class,oDesktop);
        	
        	// create document
        	XComponent document = xCLoader.loadComponentFromURL("private:factory/swriter", "_blank", 0,new PropertyValue[0]);
        	XTextDocument xTextDocument = (XTextDocument)UnoRuntime.queryInterface(XTextDocument.class,document);
        	XText xText = xTextDocument.getText();
        	
        	// create a paragraph cursor
        	XParagraphCursor xParagraphCursor = (XParagraphCursor) UnoRuntime.queryInterface(XParagraphCursor.class, xText.createTextCursor());
        	
        	// add some text
        	xText.insertString(xText.getEnd(), "My First OpenOffice Document",false);
        	
        	// style the paragraph
        	XPropertySet xPropertySet = (XPropertySet) UnoRuntime.queryInterface(XPropertySet.class, xParagraphCursor);
        	xPropertySet.setPropertyValue("ParaStyleName", "Heading 1");
        	

        	// add some text
        	xText.insertString(xText.getEnd(),"rThis is the first line in my paragraph. " + "Some more text, just to add some text to this document. ",
        	false);
        	xPropertySet.setPropertyValue("ParaStyleName", "Text body");

        	// Add another heading paragraph
        	xText.insertString(xText.getEnd(), "rSecond heading", false);
        	xPropertySet.setPropertyValue("ParaStyleName", "Heading 2");

        	// And another text body paragraph
        	xText.insertString(xText.getEnd(),"rThis is the second normal paragraph.", false);
        	xPropertySet.setPropertyValue("ParaStyleName", "Text body");
        	
        	// save document
        	XStorable xStorable = (XStorable) UnoRuntime.queryInterface(XStorable.class, document);
        	PropertyValue[] storeProps = new PropertyValue[0];
        	xStorable.storeAsURL("file:///tmp/first_document.odt", storeProps);
        	
        	// export document to pdf
        	storeProps = new PropertyValue[1];
        	storeProps[0] = new PropertyValue();
        	storeProps[0].Name = "FilterName";
        	storeProps[0].Value = "writer_pdf_Export";
        	xStorable.storeToURL("file:///tmp/first_document.pdf", storeProps);
        	
        	// close document
        	XCloseable xcloseable = (XCloseable) UnoRuntime.queryInterface(XCloseable.class, document);
        	xcloseable.close(false);
		} catch (BootstrapException e) {
			e.printStackTrace();
		}
		catch( Exception e)
		{
			e.printStackTrace();
		}
	}
}

and I am getting below Exception:

com.sun.star.comp.helper.BootstrapException: no office executable found!
at com.sun.star.comp.helper.Bootstrap.bootstrap(Boots trap.java:253)
at Converter2.main(Converter2.java:22)


System Environment:
OS : Windows XP
IDE : Eclipse 3.5
JDK: 1.6
Open Office Version: 3.2 (latest)

Below configurations made manually:

set the PATH environment variable to : C:\Program Files\OpenOffice.org 3\program to search for soffice.exe

&

set CLASSPATH environment variable to :
D:\test\Jars\unoil-2.2.0.jar;
D:\test\Jars\juh-2.3.1.jar;
D:\test\Jars\jurt-2.3.1.jar;
D:\test\Jars\ridl-2.3.1.jar;
C:\Program Files\OpenOffice.org 3\Basis\program\classes

I installed C:\OOo\OOffice3\OpenOffice.org3 at location.

Please help me to clear this error and able to create a sample word document.

As I said, I am not a developer, even less a windows developer.
But as the output complains about binary not found, then either

• the path is wrong
• the path needs to be escaped, as there are white spaces in it (also I am not sure about / versus \ directory delimiter
• com.sun.star.comp.helper.BootstrapException *maybe* doesnt use path

Try, with and without the quotes,

SET UNO_PATH="C:\Program Files\OpenOffice.org 3\program"

, i.e, to the dir where soffice.exe is found.
