A problem about jar ....

I'm not sure where my problem fits, but because it's related to EJB, i post it here .
Here is the situation :
I want to apply for a job. The company requires the applicants to create an EJB application implementing an interface given by the company. From my application, i will get the home object, create the ejb object, and pass my data by calling the corresponding method.
Then, i need to jar them all(classes, my CV) and upload the jar-bundle to them, via their upload-servlet@their web page. My app will get executed there, and the if any runtime errors occur, they'll get printed on my browser.
Here's my problem :
One of the required method in my class was meant to read my CV which is in word-format.
jobApplication.setCurriculumVitae(byte[] buff);
The buff represents my CV.doc binary. Here comes the problem. How do i read my data from a file which is inside a jar file ?
I've tried several ways. I've tried out the plain FileInputStream which results in FileNotFoundException. I've tried out ClassLoader.getSystemResourceAsStream("CV.doc"), and it apparently returns null. Please help.

Hi,
You have to use JarInputStream for this. Follow the steps and u can easily read the file..
1) Create a JarInputStream for the jar file..
2) Get the ZipEntry from the stream and check for ur CV.doc.
3) Create a ZipFile and get the InputStream for the file by passing the ZipEntry to the getInputStream().
Hope u can proceed after this..
Best wishes.. lemme know if u get the job..
Cheers
