hi,

i am using file upload interceptor for file uploads.
If i mention a static path the file is getting stored in that location. if i mention the path using context.getRealPath("/"); it is storing in eclipse workshop internal .
folders.The Eclipse workspace is in D: folder. My application name is Struts2proj and the actual file should be stored in Struts2proj/Images.
but when i print the filepath it is showing in this way " D:\Workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\Struts2proj\Images"

here is the code

import java.io.File;

import javax.servlet.ServletContext;
import javax.servlet.http.HttpServletRequest;
import org.apache.commons.io.FileUtils;
import org.apache.struts2.ServletActionContext;

import com.opensymphony.xwork2.ActionSupport;

public class FileUploadAction extends ActionSupport implements ServletContextAware,
ServletRequestAware {
private File userImage;
private String userImageContentType;
private String userImageFileName;

private HttpServletRequest servletRequest;
// ServletContext context = ServletActionContext.getServletContext();
ServletContext context;

public void setServletContext(ServletContext context) {
this.context = context;
}


public String execute() {
try {

String filePath = context.getRealPath("/")+"Images";

System.out.println("Server path:" + filePath);

File fileToCreate = new File(filePath, this.userImageFileName);

FileUtils.copyFile(this.userImage, fileToCreate);


} catch (Exception e) {
e.printStackTrace();
addActionError(e.getMessage());

return INPUT;

return SUCCESS;

What I am doing is capturing a biometric information ,returns a byte[] so I needed to convert it from
byte[] to a string that I could set as a url parameter and passing it as url parameter, so &m=(biometric info).

in the receiving servlet , i am able to decode to string.
my question is how how to get the actual byte array value in the servlet.
