Reading Excel from src folder using JXL

Question

I am a beginner and having a hard time to get my program run correctly after exporting it as runnable JAR.

I need to read an Excel called "bstn.xls", which is in the dDefault package such as all other classes. Here is how I did it.

1. get the file path with: URL excelURL = this.getClass().getClassLoader().getResource("bstn.xls");
2. Create a File with the URL File file = new File(new ResourceLoader().loader());
3. Create a workbook with the file wbook = Workbook.getWorkbook(file);

I got the error in german here, but it says: the System cannot find the given path. Is JXL not able to read with the full qualified path? I can't find anything on the JXL site.

Answer 1

Since the file is in the classpath, you may use the getWorkbook method taking an InputStream parameter :

InputStream stream = this.getClass().getClassLoader().getResourceAsStream("bstn.xls");
wbook = Workbook.getWorkbook(stream);
