I have a problem with DotImport tool of Zest 2.0 Plugin for Eclipse.

I have a application RCP and I want import a DOT file and view this DOT in Graph form.

For this, I call DotImport just like this:

1. DotImport dot = new DotImport(new File("c:/dot/"));
2. Graph graphs = dot.newGraphInstance(arg0, SWT.NONE);

The content of file is:
digraph G { main -> parse -> execute;main -> init;main -> cleanup;execute -> make_string;execute -> printfinit -> make_string;main -> printf;execute -> compare;}

When I execute the application jump this exception: (the exception come for DotImport , line 1.)

Error injecting method, javax.xml.parsers.FactoryConfigurationError: Provider org.apache.xerces.jaxp.SAXParserFactoryImpl not found
at org.eclipse.xtext.conversion.impl.AbstractDeclarativeValueConverterService.setGrammar

Any idea of the problem??

Thank you very much!!

Sounds like some kind of dependency issue - what version of Eclipse do you use and how did you install Zest? Do you know if you already had Xtext installed when you installed Zest?

You could try to reproduce the problem with a fresh Eclipse 4.2.2 SDK and Zest from the GEF4 integration site (
