For anyone interested in an option, what I would like to do is given
below. Anyone have any suggestions on the best way to do this and still
use ActionForm, short of rewriting ActionForm? Thanks for any
assistance. (The UploadFileItem is just a simple Serialized wrapper of
commons' FileItem. This wrapper utilizes a buffered input stream.)
public class UploadParser {
public UploadParser() {
}
public void parse(HttpServletRequest req,
Vector uploadListeners,
int fileSizeLimit,
Hashtable parameters,
Hashtable files,
String tmpFolder,
String encoding)
throws IOException {
DiskFileUpload dfu = new DiskFileUpload();
dfu.setSizeMax(fileSizeLimit);
dfu.setSizeThreshold(UploadConstant.MEMORY_BUFFER_SIZE);
dfu.setRepositoryPath(tmpFolder);
if(encoding != null) {
dfu.setHeaderEncoding(encoding);
}
List list = null;
try {
list = dfu.parseRequest(req);
} catch(FileUploadException fue) {
throw new IOException(fue.getMessage());
}
Object obj = null;
for(Iterator iter = list.iterator(); iter.hasNext();) {
FileItem fi = (FileItem)iter.next();
String fieldName = fi.getFieldName();
if(fi.isFormField()) {
String holder = null;
if(encoding != null) {
holder = fi.getString(encoding);
} else {
holder = fi.getString();
}
Vector params = (Vector)parameters.get(fieldName);
if(params == null) {
params = new Vector();
parameters.put(fieldName, params);
}
params.addElement(holder);
} else {
String fin = fi.getName();
if(fin != null) {
UploadFileItem ufi = new UploadFileItem(fi);
fin = fin.replace('\\', '/');
int j = fin.lastIndexOf("/");
if(j != -1) {
fin = fin.substring(j + 1, fin.length());
}
ufi.setFileName(fin);
ufi.setContentType(fi.getContentType());
ufi.setFileSize(fi.getSize());
files.put(fieldName, ufi);
}
}
}
}
}
public class UploadFileItem
implements Serializable {
private FileItem fi;
private String contentType;
private String fileName;
private long fileSize;
public UploadFileItem() { this.fi = null; }
public UploadFileItem(FileItem fi) { this.fi = fi; }
public FileItem getFileItem() { return fi; }
public long getFileSize() { return
fileSize; }
public String getFileName() { return
fileName; }
public String getContentType() { return
contentType; }
public void setFileSize(long fileSize) { this.fileSize
= fileSize; }
public void setFileName(String fileName) { this.fileName
= fileName; }
public void setContentType(String contentType) {
this.contentType = contentType; }
public InputStream getInputStream() {
if(fi == null) {
return null;
}
InputStream is = null;
try {
is = new BufferedInputStream(fi.getInputStream());
} catch (IOException ioe) {
StdOut.log("log.error",ioe.getMessage());
}
return is;
}
public byte[] getData() {
InputStream is = getInputStream();
if(is != null) {
int i = (int)getFileSize();
if(i > 0) {
byte data[] = new byte[i];
try {
is.read(data);
is.close();
} catch(IOException ioe) { }
return data;
} else {
return null;
}
} else {
return null;
}
}
public void reset() {
if(fi != null) {
fi.delete();
}
}
}
