Loading an input stream in Java

If you�want to load a resource using a specified name from the search path in your java application you need to take into account the following rules :

If your file is located in a file structure like this :

/reporting/sampleReport.xml

You can reach it using the following java snippet :

InputStream reportTemplate = getClass().getClassLoader().getResourceAsStream("reporting/sampleReport.xml");

The method getResourceasStream() in ClassLoader use the given String as the name of the resource without applying any absolute/relative transformation (see the methods in Class). The name should not have a leading slash (/).

Or if you don't access it using the class loader you need to use the slash (/) at the beginning of your resource path.

InputStream reportTemplate2 = getClass().getResourceAsStream("/reporting/sampleReport.xml");
