Problem in uploading an image into a CM repository!!

Question

Hi All,
     I am trying to use the Fileupload element in JSP dynpage.
     My screen has the Fileupload element and a button.
     <b>I want to upload an image into a CM repository.</b>
     I have put <hbj:form id="myFormId" encodingType="multipart/form-data" > in my jsp page.
     The <b>'onClick'</b> method is <b>'onLoadFile'</b>.
     <i><b>The following is my code:</b></i>
public void onLoadFile(Event event)
               FileUpload fu =
                    (FileUpload) this.getComponentByName("myfileupload");
               if (fu != null) {
                    //    Get file parameters
                    IFileParam fileParam = fu.getFile();
                    //    Get the temporary file name
                    File f = fileParam.getFile();
                    String fileName = fileParam.getFileName();
                    //    Get the selected file name
                    String ivSelectedFileName = fu.getFile().getSelectedFileName();
                    try {
                         int len = (int) f.length();
                         byte a[] = new byte[len];
                         FileInputStream fin = new FileInputStream(f);
                         fin.read(a);
                         String FileContent = a.toString();
                         IPortalComponentRequest request =
                              (IPortalComponentRequest) this.getRequest();
                         com.sapportals.portal.security.usermanagement.IUser user =
                              (com.sapportals.portal.security.usermanagement.IUser) request.getUser().getUser();
                         IResourceFactory factory = ResourceFactory.getInstance();
                         IResourceContext context = new ResourceContext(user);
                         RID rid = RID.getRID("/documents/test");
                         IResource resource = factory.getResource(rid, context);
                         if (resource != null) {
                              ICollection parent =
                                   (ICollection) ResourceFactory
                                        .getInstance()
                                        .getResource(
                                        rid,
                                        context);
                              String out = new String(FileContent);
                              ByteArrayInputStream data =
                                   new ByteArrayInputStream(out.getBytes());
                              IContent content =
                                   new Content(data, "text/html", data.available());
                              IResource fileResource =
                                   parent.createResource(fileName, null, content);
                    } catch (Exception e) {
               <b>..... REMAINING CODE...</b>
I uploaded <b>abc.jpg (<i>size: 2KB</i>)</b>, then, an image file with the same-name is being created in the <b>/documents/test</b> folder but the size is <b>10Bytes</b> only. <b>I am not able to see the image</b> too.

I would guess that this is because of the way you try to read the file contents. Maybe you should add some debug statements to find out what you're realling setting as content. It's certainly not KM's fault.
The following sequence of statements looks wrong:
nt len = (int) f.length();
byte a[] = new byte[len];
FileInputStream fin = new FileInputStream(f);
fin.read(a);
String FileContent = a.toString();
IPortalComponentRequest request =
(IPortalComponentRequest) this.getRequest();
com.sapportals.portal.security.usermanagement.IUser user =
(com.sapportals.portal.security.usermanagement.IUser) request.getUser().getUser();
IResourceFactory factory = ResourceFactory.getInstance();
IResourceContext context = new ResourceContext(user);
RID rid = RID.getRID("/documents/test");
IResource resource = factory.getResource(rid, context);
if (resource != null) {
ICollection parent =
(ICollection) ResourceFactory
.getInstance()
.getResource(
rid,
context);
String out = new String(FileContent);
ByteArrayInputStream data =
new ByteArrayInputStream(out.getBytes());
IContent content =
new Content(data, "text/html", data.available());
Why don't you just pass the FileInputStream into the Content object's constructor???
