PLEASE, HELP !!! upload problem
Hello All !
I use the Struts v.1.0.2
Unfortunatelly I can't realize file uploading.
And the most confusing that I have 2 different errors on different
files with the same code.
Here's my form:
<html:form action="/addImage.do" enctype="multipart/form-data" >
<html:hidden property="pkPartner" />
<html:file property="imgFile" />
<br>
<html:submit property="submit" value="Save" />
<html:reset/>
</html:form>
Here's form bean:
...
public final class ImagesPartnerForm extends ActionForm {
private String pkPartner = null;
private FormFile imgFile = null;
...
public FormFile getImgFile(){
return this.imgFile;
}
public void setImgFile( FormFile imgFile ){
this.imgFile = imgFile;
}
public void reset( ActionMapping mapping, HttpServletRequest request ){
pkPartner = (String)request.getAttribute( "pkPartner" );
imgFile = null;
}
...
Here's action that handles form data:
public final class AddImage extends ActionExt {
public ActionForward perform( ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response, String userName )
throws IOException, ServletException
{
String subpath = "/partner";
String targetDir = ResourceHandler.getProperty( "global",
"pictures.dyn.abs-root" ) + subpath;
String dbPath = ResourceHandler.getProperty( "global",
"pictures.dyn.rel-root" ) + subpath;
ImagesPartnerForm iform = (ImagesPartnerForm)form;
FormFile ff = iform.getImgFile();
//
String name = ff.getFileName();
String targetFile = targetDir + "/" + name;
String dbFile = dbPath + "/" + name;
// Save file to filesystem
java.io.DataInputStream dis = new java.io.DataInputStream(
ff.getInputStream() );
java.io.DataOutputStream dos = new java.io.DataOutputStream(
new java.io.FileOutputStream( targetFile ) );
for( int i = 0; i < ff.getFileSize(); i++ ){
dos.writeByte( dis.readByte() );
}
dos.flush();
dos.close();
dis.close();
return new ActionForward( "/jsp/partner/test.jsp" );
}
}
ERRORS:
0) short text file was uploaded without any corruption, but:
1) One jpeg file was uploaded, but had less size then source.
2) Other jpeg file uploading caused an exception:
javax.servlet.ServletException: IOException while reading file element: Premature end of stream while reading multipart request

Re: PLEASE, HELP !!! upload problem

I uploaded graphics just fine just now. My code is slightly different than
yours. I simply call the getFileData() method of FormFile to return the
data, and write it all out at once. Then flush the buffer and close the
file.
Try something along the lines of:
FormFile ff = ... get the FormFile field
FileOutputStream fos = new FileOutputStream("/some/path/" +
ff.getFileName());
fos.write(ff.getFileData());
fos.flush();
fos.close();
If you still have problems let us know. I have to warn you, however, that
people don't seem to care about file uploads. I asked for help and never
got it. Of course my mistakes were because I was new, and a small amount of
experimentation got me where I needed to go, but it's still annoying to be
totally ignored.
Hope that helps! Let us know if it does not.
Eddie
