Java EE (Java Enterprise Edition) General Discussion

Hello folks,

I have come accross a requirement, on the project I am working on, to upload images and doc files to MySql database from an upload perfomed on a jsp page. The upload is made thru a multipart/form-data form and the file upload handling is made by a servlet with the use of org.apache.commons.fileupload.MultipartStream(had to use this as input types other than file are also being passed on the request). I am able to get all the input correctly and have them inserted on the database, but my doubt relies on the fact that I receibe all uploaded bytes into a String variable and get the bytes from it into a byte array as String.getBytes. That is where my first question goes, is that right? If the string contains the bytes of the file, convertint]g it to ByteArrays would still contain the bytes of the file? The after doing that, all data is successfully inserted on the database. When I want to retrieve it from a database, I am not able to get the image(file) correctly retrieved though. I hava a bean that receives the byte array and when trying to get that to the JSP page through the use of ${class.object} I get nothing. I know this is way to confusing but can anybody get their times in trying to light me out on this?

Here is how I am getting the request params on the servlet:

while(nextPart) {
		  String headers = multipartStream.readHeaders();
		  System.out.println("Headers: " + headers);
		  System.out.println("Item name: " + headers.substring(38));
		  String item = headers.substring(38);
		  ByteArrayOutputStream data = new ByteArrayOutputStream();
		  multipartStream.readBodyData(data);
		  String value = new String(data.toByteArray());
                  (...)
                  nextPart = multipartStream.readBoundary();
}

This is my bean:

public class PropertyPictures {
	private int pictureID;
	private String title;
	private byte[] image;
	private String description;
	private Property property;
        (setters and getters)
}

This is how I am retrieving the image on the Jsp page:

<td><img class="houseimage" src="data:image/jpg;base64,${pictures.image}" alt="${pictures.description}"/></td>

I hope some one can help me with this.

Thanks and regards,
TS
