Problem with File Upload using SmartUpload class.

Hello.
I need to get a file from client browser. I have HTML form that has mixed data, parameters and files submitted to server. I looked through the forum messages and got the, recommended by many, SmartUpload class. The problem is: when I call SmartUpload.upload() method my system hangs. It takes forever to download a file that is 20Kb. Below is the code from my source:
SmartUpload su = new SmartUpload();
su.initialize(getServletConfig(), req, res);
su.upload(); <--- It stops right here forever...
Enumeration enum = su.getRequest().getParameterNames();
I tried the com.oreilly.servlet.multipart.MultipartParser class, also mentioned in forum messages. I used exactly the same html page to submit the same file and other parameters. It worked just fine. The only reason I need SmartUpload class is because it has getParameterValues(�) method that returns String array of values.
Do you have any idea what is going on? If you know how to get array of values and file(s) without using SmartUpload from a html page, please help me with it.
Thank you for any suggestions.

I looked at MultipartRequest class before but the problems is that it saves upload file directly to disk (push technology). I need to save this file into an XML database, using InputStream, (the upload file is normally xml document or an image).

Problems with file upload using AMF or SOAP

We use your AMF to connect Flex with Ruby on Rails.
Everything is OK, except file upload.
We did not find how to upload file using AMF or SOAP RPC from
Flex. Only to use FileReference.upload().
The problem is that Flex uses different User-Agent in HTTP
header for this upload and for SOAP/AMF calls.
This means that sessions are different. And even if you
authenticated via SOAP/AMF you can not use it to upload file.
Could you, please, advice is there any other way to upload
files from Flex via SOAP or AMF?

Please, help me on this issue, i am still waiting for someone replying me!

Newbie : memory problem with file uploading

Hello
I'm exdending a web app based on jsf and , being new to it and java in general, i'm having a problem with file uploading.
The customer needs to upload large file (more than 30 MB). The application accomplish this using a fileupload component, to let the user select the file, and passing the array of bytes to a web service method.
I'm using netbeans 6, tomcat 5.5.
When i try to upload a file too large i got an outofmemory on the local tomcat. So i've rised jvm memory and going on with tests i've found that growing the size i got an http 500 error from the service (the developer of the service has found an out of memory too ).
I think the service is not modifiable, so i were asking if threre were a way to optimize the file uploading process (a component, a library, a pattern ...) or my only chioice is to rise available memory on both sides.
I've notice the wsdl declares as base64binary type the data parameter , while netbeans 6 generates a client proxy with a byte[] parameter. Is correct or is a netbeans problem?
searching with google i've found few thing i haven't fully understood due to my lack of experience:
the mtom , how can evaluate if it's suitable to help in my problem (i suppose it involves more the web service rather than the client)
something about the size of a soap body.
thank you in advance
Stefano

Which component exactly are you using? Declaring the stream as a raw byte[] is certainly not efficient. Write code yourself, don't let it autogenerate.
I can highly recommend you the Tomahawk t:inputFileUpload component. It is easy to integrate in Mojarra. You can find here an useful article: [http://balusc.blogspot.com/2008/02/uploading-files-with-jsf.html].

I remember that there was a bug in the MultipartHandler of the BC4JRequestProcessor in one of the 10.1.2.x version, however I'm nit sure which one. I found the old fix we implemented back then
Try this request processor and see if this helps:

        if (HtmlServices.isMultipartPost(request)) {
            MultipartRequestHandler handler = MultipartUtil.retrieveMultipartHandler(request);
            if (handler == null) {
                try {
                    request = MultipartUtil.parseMultipartRequest(request, servlet);
                catch (ServletException se) {
                    throw new RuntimeException(se.getMessage());
            else {

Problem with file permissions using Snow Lepord

I'm having problems with file Sharing & Permissions using Snow Lepord.
When I save any new file it only has 'Read & Write' privileges for the user, everyone else is 'read only' or 'no access'.
We have a Netgear NAS Server which is accessed by other users over the local network and if I change the Privilege to 'read & write' via Get Info and then copy the file from my desktop to ther server it changes the Privilege of the server version to 'no access' we then have to change it again for it to work.
I also created a new folder on the server and now it says 'no access' and has a no entry icon!
Any ideas???

We have issues like this. Have tried running AFP and SMB, now connecting using CIFS. All have the same problem. I can work on one or two files fine, then suddenly, one of the files I just worked on says I don't have permissions. I log off the server and log back on, and then I have permissions to the file. It will work fine for one or two operations, then fails. We just updated to OSX Mavericks and a Windows 2012 server, but have been having this issue for years. My permissions look fine. I can even change permissions, but it won't let me work on the file or move or delete the file or rename the file. Once I log out and log back in, I can do anything I want.

Problem with file upload

Hi all, my problem has something to do with internal working of pageflow.
Here is what has happened:
1. I have a page with a few portlets on it.
2. One of the portlet is for uploading file (lets call it upload portlet)
3. The rest of the portlet need to access the PortletBackingContext using the following code (put in a jpf):
PortletBackingContext portletCtx = PortletBackingContext.getPortletBackingContext(super.getRequest());
4. When the upload portlet transfers the file, the other portlets will refresh (i'm using refreshAction attribute).When the other portlets refresh, they can't get the PortletBackingContext. It always returns null.
If I remove the enctype="multipart/form-data" from the netui:form tag, it works as per normal (but of course the file uploading fails).
Any idea?
Thanks.

Problem with File Uploads

Hello all. Has anybody successfully got the UploadFilter classes -- as listed in Hortsmann and Geary's "Core JSF" -- going?
Everytime I submit a multipart form, I am not redirected to the appropriate next page (as specified in the navigation cases) . I have definitely set up the UploadFilter correctly, and any multipart form requests are getting parsed and uploaded into the correct directory. The only problem is that the resulting page isn't the one specified in faces-config.xml -- it's the original upload page.
If I get rid of the multipart/form-data encoding for the form, it works "okay" (in the sense that the file upload no longer works, but the behaviour matches the navigation cases).
I'm beginning to wonder whether the fact the form is a multipart form means that the submit button's action -- which is set to "submit", matching a value in faces-config.xml -- isn't being correctly parsed. Are there any "gotchas" I should be aware of in these cirumstances?

Hi diritchie,
perhaps that thread helps you.
http://forum.java.sun.com/thread.jsp?forum=427&thread=473135
There are posts of some clazzes, to enable upload.
the clazzes are using Jakarta Commons FileUpload
btw. in MyFaces there is allready an upload-component.

Problems with File Upload on BEA WLS 6.1

I encountered a problem with Jason Hunters File Upload Classes.
When uploading a file I always get this exception:

Going directly with the HttpServletRequest doesn't help.
Can anybody help me out on this one? Thanks in forward.

The line of code that brings up this exception is:
multiReq = new

try this: MultipartRequest multiReq = new MultipartRequest((ServletRequest)request,

Problem with constructors and using public classes

Hi, I'm totally new to Java and I'm having a lot of problems with my program :(
I have to create constructor which creates bool's array of adequate size to create a sieve of Eratosthenes (for 2 ->n).
Then it has to create public method boolean prime(m) which returs true if the given number is prime and false if it's not prime.
And then I have to create class with main function which chooses from the given arguments the maximum and creates for it the sieve
(using the class which was created before) and returns if the arguments are prime or not.
This is what I've written but of course it's messy and it doesn't work. Can anyone help with that?
//part with a constructor
public class ESieve {
ESieve(int n) {
boolean[] isPrime = new boolean[n+1];
for (int i=2; i<=n; i++)
isPrime=true;
for(int i=2;i*i<n;i++){
if(isPrime[i]){
for(int j=i;i*j<=n;j++){
isPrime[i*j]=false;}}}
public static boolean Prime(int m)
for(int i=0; i<=m; i++)
if (isPrime[i]<2) return false;
try
m=Integer.parseInt(args[i]);
catch (NumberFormatException ex)
System.out.println(args[i] + " is not an integer");
continue;
if (isPrime[i]=true)
System.out.println (isPrime[i] + " is prime");
else
System.out.println (isPrime[i] + " is not prime");
//main
public class ESieveTest{
public static void main (String args[])
public static int max(int[] args) {
int maximum = args[0];
for (int i=1; i<args.length; i++) {
if (args[i] > maximum) {
maximum = args[i];
return maximum;
new ESieve(maximum);
for(int i=0; i<args.length; i++)
Prime(i);}

I've made changes and now my code looks like this:
public class ESieve {
ESieve(int n) {
   sieve(n);
public static boolean sieve(int n)
     boolean[] s = new boolean[n+1];
     for (int i=2; i<=n; i++)
s=true;
for(int i=2;i*i<n;i++){
if(s[i]){
for(int j=i;i*j<=n;j++){
s[i*j]=false;}}}
return s[n];}
public static boolean prime(int m)
if (m<2) return false;
boolean x = sieve(m);
if (x=true)
System.out.println (m + " is prime");
else
System.out.println (m + " is not prime");
return x;}
//main
public class ESieveTest{
public static int max(int[] args) {
int maximum = args[0];
for (int i=1; i<args.length; i++) {
if (args[i] > maximum) {
maximum = args[i];
return maximum;
public static void main (String[] args)
int n; int i, j;
for(i=0;i<=args.length;i++)
n=Integer.parseInt(args[i]);
int maximum=max(args[]);
ESieve S = new ESieve(maximum);
for(i=0; i<args.length; i++)
S.prime(i);}
It shows an error for main:
{quote} ESieveTest.java:21: '.class' expected
int maximum=max(args[]); {quote}
Any suggestions how to fix it?

Architectural Problem with file upload feature. URGENT!!!

Hi,
          We have an architecture in a production site which has iPlanet in the front & WebLogic at the back. The web-tier and the middle-tier both reside on the WebLogic server & only the static assets (images, PDFs etc.) are serviced by iPlanet. Recently we had to incorporate a new feature to our existing site to allow the user to upload images onto the server. The problem with this is that since our web-tier is in WebLogic, the uploaded file would reside in the WebLogic server's document root and will not be accessible to the iPlanet server. Is there any way that I can store the images directly in iPlanet even though the servlets reside on WebLogic. I know this query sounds a bit weird & I'm asking for too much but I also have this feeling the architecture of our site is not very different from a lot of other sites & other sites also have upload functionalities, so how do they go about dealing with this problem. Porting the web-tier to iPlanet is not a solutions since there are a lot parties involved & we cannot at this point take that decision.
          Would really appreciate any help from you guys.
          Thanks in advance,
          VD.


u can have AppServers serve the image if u want to.
          u just need to set the path correctly and save them in the right directory.
          we are already doing it with Iplanet and we wrote a sample for Weblogic6.1 too.
          if i remember correctly u need to put the image directiry say "imageDirectory" in "wlserver6.1"
          then u need to access via http://apache_webserver_box:80/weblogic_identifier/imageDirectory/myimage.jpg
          Hope it helps!!!

Hi, thank you for your replies, I found out few things about my servlet, and its portability
and i have few questions, although i marked this topic as answered i guess its ok to post
I am using javax.servlet.context.tempdir to store my files in that servletcontext temporary directory. But i dont know how to give hyperlink
of the modified files to the user for them to download the modified files.
What i am using to get the tempdir i will paste
File baseurl = (File)this.getServletContext().getAttribute("javax.servlet.context.tempdir");
System.out.println(baseurl);
baseurl = new File(baseurl.getAbsolutePath()+File.separator+"temp"+File.separator+"files");
baseurl.mkdirs();so i am storing my files in that temp/files folder and the servlet processes them and modifies them, then how to present them as
links to the user for download ?
and as the servlet is multithreaded by nature, if my servlet gets 2 different requests with same file names, i guess one of them will be overwritten
And i want to create unique directory for each request made to the servlet , so file names dont clash.
one another thing is that i want my servlet to be executed by my <form action> only, I dont want the user to simply type url and trigger the servlet
Reply A.S.A.P. please..
Thanks and regards,
Mihir Pandya

    <description>If this parameter is true, there will be an automatic check of the modification date of your JSPs, and saved state will be discarded when JSP's change. It will also automatically check if your skinning css files have changed without you having to restart the server. This makes development easier, but adds overhead. For this reason this parameter should be set to false when your application is deployed.</description>

Hi,
It works for me, the only difference is I am using parameters from trinidad's packages
    <context-param>
        
        <param-name>org.apache.myfaces.trinidad.UPLOAD_MAX_MEMORY</param-name>
        
        <param-value>512000</param-value>
    </context-param>
    <context-param>
        
        <param-name>org.apache.myfaces.trinidad.UPLOAD_MAX_DISK_SPACE</param-name>
        
        <param-value>5120000</param-value>
    </context-param>Try it, maybe it will work.

Performance Problem with File Adapter using FTP Conection

Hi All,
I have a pool of 19 interfaces that send data from R/3 using RFC Adpater, and these interfaces generate 30 TXT files in a target Server. I'm using File Adapters as Receiver Comunication Channel. It's generating a serious perfomance problem. In File Adpater I'm using FTP Conection with Permanently Conection, Somebody knows if PERMANENTLY CONECTION is the cause of performances problem ?
These interfaces will run once a day with total of 600 messages.
We still using a Test Server with few messages.

Hi Regis,
We also faced teh same porblem. Whats happening is that when the FTP session is initiated by the file adapter, then its getting done from teh XI server. Hence the memory of the server is also eaten up. Why dont you give a try by using 'per file transfer'.
If this folder to which you are connecting is within your XI server network then you can mount(or map) that drive to the XI server and use it with a NFS protocol of the file adapter and thereby increasing the performance.
Cheers
JK
