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
