Hi Enrique,

Of course it's possible.

In order to open an Excel document you can use one of the following approaches:

1) Open a document using the OleContainer.createObject(File) method. For example, in the ExcelIntegrationSample.java class you need to change one line only:

// _container.createObject(DOCUMENT_PROGID);
_container.createObject(new File("C:\\FileName.xls"));

2) Open a required document via Excel API, using the generated stubs:

_Application application = getApplication();
Workbooks workbooks = application.getWorkbooks();
Variant unspecified = Variant.createUnspecifiedParameter();
workbooks.open(new BStr("C:\\FileName.xls"),
        unspecified,
        unspecified,
        unspecified,
        unspecified,
        unspecified,
        unspecified,
        unspecified,
        unspecified,
        unspecified,
        unspecified,
        unspecified,
        unspecified,
        unspecified,
        unspecified,
        new Int32(0));

3) Open a required document using Automation:

IDispatch workbooks = ...;
 
Automation workbooksAutomation = new Automation(workbooks, true);
workbooksAutomation.invoke("open", "C:\\FileName.xls");

Please let me know if you have another questions.
