Open excel document in java

I want to open excel document from my program in java. Actually I want excel document to be opened when I click on button in my program. I have tried

Runtime.getRuntime().exec("workbook.xls");

where workbook.xls is located in the root of pro开发者_C百科ject folder, but it doesn't work. Exception says that it can not open program workbook.xls. How can I do this

I guess you want to open your Excel-file with it's default program (like Excel)? If so, you can use the Desktop-class:

Desktop.getDesktop().open(new File("path/to/your/file.xls"));

You can use Apache POI to work with Microsoft documents. Have a look here for examples on how to use this.
