Session tracking for File Upload Servlet

Hey Friends,
I am developing a File Upload servlet and I need your help in certain matters .I have taken the servlet code from java-edge.com and am modifying it to give custom behaviour.I have a main page for upload (form upload)(lets call it form 1).If the file to be uploaded already exists on the server then a page is generated by the server saying that file already exists.(form 2)Now it is here(in form 2) that I want to provide an extra button which when submitted would recall the same servlet /or maybe another one and would provide the user for overriding the existing file.
Now as per the code I would set the Override flag to be false in the second form and false in the main form .
Given the case that it is a form based uploading servlet how do I maintain the user session when going to the next form or how do i pass the variables of the first form into second form .
I am also facing another problem that is how do i manage multiple file uploads at a time .This basic system allows only one file per upload .
P.S If someone could also throw some light on how to use the com.oreilly servlet (the latest version) it would be lovely but for now I want to focus on developing the current one

Hi Jocelyn,
I want to apologize firstly for the delay in my response.
I was seriously bogged down due to certain circumstances and so couldnt reply.Thanks a million for your prompt reply.I'll post the Html content here and you will find the servlet code as is at the following U.R.L
http://www.java-edge.com/Viewcode.asp?Value=serv012
Form1:
<HTML>
<HEAD>
<TITLE> Upload </TITLE>
</HEAD>
<BODY >
<h2>Upload Your File!</h2>
<form ENCTYPE="multipart/form-data" action="http://localhost:8080/servlet/Upload" method=post>
click <b> browse </b>to select the file <br>
<b> File:</b>
<input type="FILE" name="Filename" value="" MAXLENGTH=255 size=50><br>
Click here to upload!<input type=submit value=Upload>
<input type=hidden name=Directory value="G:/Workspace/Upload/">
<input type=hidden name=SuccessPage value="G:/Workspace/successpage.html">
<input type=hidden name="OverWrite" value="false">
<input type=hidden name="OverWritePage" value="">
</form>
</BODY>
</HTML>
Form 2
<HTML>
<HEAD>
<TITLE> Upload </TITLE>
</HEAD>
<BODY >
<h2>Upload Your File!</h2>
<form ENCTYPE="multipart/form-data" action="http://localhost:8080/servlet/Upload" method=post>
click <b> browse </b>to select the file <br>
<b> File:</b>
<input type="FILE" name="Filename" value="" MAXLENGTH=255 size=50><br>
Click here to upload!<input type=submit value=Upload>
<input type=hidden name=Directory value="G:/Workspace/Upload/">
<input type=hidden name=SuccessPage value="G:/Workspace/successpage.html">
<input type=hidden name="OverWrite" value="true">
<input type=hidden name="OverWritePage" value="G:/Workspace/overwritepage.html">
</form>
</BODY>
</HTML>
Now in Form 2 I would add another button which when clicked would prompt the user if he wishes to overwrite the page.
I am also posting the servlet code although I am sure u would prefer reading the one on the site

HELP! File Upload Servlet and Internet Explorer

Hello people. I hope this is an easy problem to solve...
I have a servlet upload program that works using Mozilla browser (www.mozilla.org), but for some reason it doesn't work using Microsoft IE. The servlet is also using the servlet upload API from Apache (commons).
I'm using IE version 6.0.2800.1106 in a Win98SE host computer. I get a cannot find path specified error message (see below). At work, I also get the same error message using IE, but don't know what version. The OS is XP. Unfortunately, at work, I can't install Mozilla browser (or any software-company policy) to see if Mozilla works there too. I would've like to have tested to see if the upload program worked on Mozilla on a truly remote computer.
So I figured, it must be a IE configuration issue, but darn it!! I began by resetting IE to default settings, but still have the problem, I played around with several different combinations of settings in "Tools"-->"Internet Options...", and I still get the error message. Someone PLEASE HELP ME!!!
Dunno, if it will help, I've also pasted the upload servlet source code below and the html file that's calling the upload servlet, but you still need the Apache commons file upload API.
Trust me on this one folks, for some reason it works for Mozilla, but not for IE. With IE, I can at least access web server, and therefore, the html file that calls the upload servlet , so I don't think it's a Tomcat configuration issue (version 5.0). I actually got the code for the file upload servlet from a book relatively new in the market (printed in 2003), and it didn't mention any limitations as far as what browser to use or any browser configuration requirements. I have e-mailed the authors, but they probably get a ton of e-mails...
Anyone suggestions?
Meanwhile, I will try to install other free browsers and see if the file upload program works for them too.

I'm guessing what is happening is that Mozilla tells the servlet "here comes the file myfile.zip". The servlet builds a file name for it:
    String path = sc.getRealPath("/files");
    // path is now C:\TOMCAT\webapps\MyWebApps\files\
    fi.write(new File(path, fi.getName()));
    // append myfile.zip to "path", making it C:\TOMCAT\webapps\MyWebApps\files\myfile.zipIE, however, tells "here comes the file C:\WINDOWS\Desktop\myfile.zip". Now imagine what the path+filename ends up being...
So what you want to do is something along the lines of (assuming Windoze):
public static String basename(String filename)
    int slash = filename.lastIndexOf("\\");
    if (slash != -1)
        filename = filename.substring(slash + 1);
    // I think Windows doesn't like /'s either
    int slash = filename.lastIndexOf("/");
    if (slash != -1)
        filename = filename.substring(slash + 1);
    // In case the name is C:foo.txt
    int slash = filename.lastIndexOf(":");
    if (slash != -1)
        filename = filename.substring(slash + 1);
    return filename;
    fi.write(new File(path, basename(fi.getName()));
    ....You can make the file name check more bomb proof if security is an issue. Long file names trying to overflow something in the OS, NUL characters, Unicode, forbidden names in Windos (con, nul, ...), missing file name, ...

ALBPM 6.0 : The maximum size for file uploads has been exceeded.

Hi,
I use AquaLogic BPM Entreprise server to deploy my Process. When I try to publish a process on my server I get the following error:
An unexpected error ocurred.
The error's technical description is:
"javax.servlet.jsp.JspException: null"
Possible causes are:
The maximum size for file uploads has been exceeded.
If you are trying to publish an exported project you should publish it using the remote project option.
If you are trying to upload the participant's photo you should choose a smaller one.
An internal error has ocurred, please contact support attaching this page's source code.
Has someone resolve it?
Thank's.

Hi,
Sure you've figured this out by now, but when you get the "Maximum size for file uploads" error during publish consider:
1. if your export project file is over 10mb, use "Remote Project" (instead of "Exported Project") as the publication source. That way when you select the remote project, you will point to ".fpr" directory of the project you are trying to publish.
Most times your project is not on a network drive that the server has access to. If this is the case, upload the .exp file to the machine where the Process Administrator is running, then expand it in any directory (just unzip the file). Then, from the Process Administrator, use the option to publish a Remote Project by entering the path to the .fpr directory you just created when unzipping the project.
2. Check to see if you have cataloged any jars and marked them as non-versionable. Most of the times the project size is big just because of the external jar files. So as a best practice, when you do a project export select the option "include only-versionable jars", that will get reduce the project size considerably (usually to Kb's). Of course you have to manually copy the Jar files to your Ext folder.

BI IP --- Planning function for File Upload

Hai All,
In BI IP , When I am trying to load the data (text file) by using Planning function for File Upload. I am getting an error message When I am clicking on Update .
Error Message : Inconsistent input parameter (parameter: <unknown>, value <unknown>).
In Text file I am using Tab Separation for each value
Anyone help me out.
Thanks,
Bhima

Hi Bhima
Try one of these; it should work:
1. If you are on SP 14 you would need to upgrade to SP 15. It would work fine
2. If not, then -
a] apply note 1070655 - Termination msg CL_RSPLFR_CONTROLLER =>GET_READ_WRITE_PROVIDS
b] Apply Correction Instruction 566059 [i.e: in Object - CL_RSPLFR_CONTROLLER GET_READ_WRITE_PROVIDS,
delete the block: l_r_alvl = cl_rspls_alvl=>factory( i_aggrlevel = p_infoprov ).
and insert block - l_r_alvl = cl_rspls_alvl=>factory( i_aggrlevel = i_infoprov ).
Goodluck

URGENT! File Upload Utility or a Custom UI for File Upload is needed!

Hi all,
I'm trying to find or develop a file upload utility or custom user interface rather than editing and adding file type item to a page. There is a free portlet for file upload in Knowledge Exchange resources, but it is for 3.0.9 release. I'm using portal 9.0.2.
I could not any sample about the new release. Also API such as wwsbr_api that is used to add item to content areas is out dated.
I create a page with a region for "items". When "edit" page and try to add an "file" type item the generated url is sth like this;
"http://host:7779/pls/portal/PORTAL.wwv_additem.selectitemtype****"
After selecting item type as a simple file autogenerated url is sth. like ;
"http://host:7779/pls/portal/PORTAL.wwv_add_wizard.edititem"
I made search about these API but could not find anything (in PDK PL/SQL API help, too).
I need this very urgent for a proof of consept study for a customer.
Thanks in advance,

Good tutorial for using the orielly file upload servlet

Hello all,
I just downloaded the packages from the orielly site and I am interested in using the upload servlet. I have the oreilly servlet book but it doesnt get into much detail about how to use the servlet. I have not used servlets before so I need basic advice or a tutorial on using the MultipartRequest servlet. Where can I find this? I checked servlets.com's FAQ but it doesnt have much about how to set it up.
TIA!

Thanks but I want to try to use the orielly servlet class I need some practice using servlets as I am relying on jsp's too much.
Anybody have any pointers on the orielly upload servlet and how to use it.

Creating Progress Bar for File Upload

Hi, I'm trying to implement a progress bar indicator for a file upload in WebDynpro, without very good results.
I'm using a fileupload UI element, a TimerTrigger and a ProgressIndicator UI elements for this purpose.
It seems that using the fileupload UI element the iview is locked during the file upload, and therefore it prevents for the timer triggered action to be performed (this action updates the progress bar).
Additionally I havent been able to capture the transfered bytes from the upload. Maybe I'm using the wrong elements?
How could I achieve this. Has anyone done it?
I would really appreciate all the help I could get.

Difficulties in creating a JSP for File upload

hello out there,
im trying to create a ProcessUpload.jsp File which should handle a file upload from a channel in the portal. regarding a previously posted thread acording to fileupload i deployed this jsp-file in the regular webServerHierarchy so that you dont have to go into the desktopServlet Portal, which cant handle fileUpload.
its location is this ../portal/test/ProcessUpload.jsp and it uses CustomTags referecens from /portal/WEB-INF/test.tld. i customized the deployment descriptor in /portal/WEB-INF/web.xml as well. but as soon as i try to put a taglib which uses this custom tags the server responses with an error.
does anybody know how to deploy a global jsp file to handle file uploads, or something in particular how to deploy jsp with custom tags outside the desktopservlet but inside the portal webapp??
i would be really thankful ;-)
best regards
martin

hi alex,
i allready tried to realize a channel with file upload download. channels are made up of jsp pages and when i am forwarding my form with enctype="multipart/form-data" encoding the desktop-servlet intercpets my entity-body.
so what kind of channel you have thought about ??
thanks for reply ;-)

Error handling for file upload

HI Experts,
I have a question on file upload process in sap MDG-S.
Scenario : Upload the content from a CSV file using the file upload prcoess.
Query : For example if there are 5 records in the file and if there is an error in 3rd record what happens to the rest of the records i.e. 1,2 and 3,4.
a) Will record 1 and record 2 get posted and record 3,4 will be failed?
b) All 4 records will not be posted as there is one errored record.
Regards,
Charita.

Hi charitha,
As per your request if there is a error in any of the record in a particular file it does'nt loads any of the fields to the target, it will be terminated with an error.
As i checked with an example of Space delimited file in which 4th field has no spaces, and i used this file as source and run the job it does'nt return any values but terminated with an error.
let me know if i am right..

Amjad

Emulating HTTP POST for file upload with J2ME

I have search through a lot of site and couldn't find the actual code. I try to emulate below html with J2ME.
<form method="POST" enctype="multipart/form-data" action="Insert.asp">
<td>File :</td><td>
<input type="file" name="file" size="40"></td></tr>
<td> </td><td>
<input type="submit" value="Submit"></td></tr>
</form>
here is my code :
HttpConnection c = null;
InputStream is = null;
OutputStream os = null;
byte[] filecontent = file byte content ...
try {
c = (HttpConnection)Connector.open("http://xx.com/insert.asp");
c.setRequestMethod(HttpConnection.POST);
c.setRequestProperty("Content-Length", String.valueOf(cmg.length + 15));
c.setRequestProperty("Content-type","multipart/form-data");
os = c.openOutputStream();
os.write("file=c:\\abc.png".getBytes());
os.write(filecontent);
os.flush();
I can emulate form with text field and it work, but when it come to file upload, above code not working, I don't know what to put for the outputstream, filename ? content ? or both ? since the html only has one field that is the "file" field. The file is actually store in rms with filename abc.png, and I just put in the c:\ for the server as a dump path.

File upload is more complicated then that... you need multi-part MIME formatting.... But I have just the code...

if ( tipo.compareTo("application/rtf") == -1 )
if ( tipo.compareTo("application/pdf") == -1 )
throw new ValidatorException(new FacesMessage("Error : los tipos de archivo aceptados son PDF, WORD y RTF"));
} catch (Exception ex) {
this.mauvaisFichier = true;
error(ex.getMessage());
public String botonValidar_action() {
if ( !this.mauvaisFichier )
if ( this.fileUpload1.getUploadedFile() != null )
if ( this.fileUpload1.getUploadedFile().getSize() > 0 )
try {
this.getSessionBean1().getComunicacion().setArchivo( new javax.sql.rowset.serial.SerialBlob(this.fileUpload1.getUploadedFile().getBytes() ) );
this.getSessionBean1().getComunicacion().setTipoArchivo( this.fileUpload1.getUploadedFile().getOriginalName().substring(this.fileUpload1.getUploadedFile().getOriginalName().length() - 3 ) );
} catch(Exception e){
e.getMessage();
return null;
I have to put a boolean value because the first time, validation code doesn't function ( the method botonValidar_action() is called ) correctly. The error message appears but empty.
If I try next time then it's ok.
Thx for any issue.

Size limit for files uploaded to htmldb_application_files

Hi,
Is there any size limit for files which are to be uploaded to htmldb_application_files (and then stored as BLOB in db)?
Regards,
Tom

Hi Tom,
the only limitation is that the BLOB data type is 4GB
large.
So you can store max. 4 GB data in BLOB.Did you mean BFILE? Depending on the version, size limit is between 8TB and 128TB, as in the 10g2 documentation:
PL/SQL LOB Types

Need help for file upload - reposted for Steve Muench

Hi Steve,
I have been involved developing a web application that requires a file upload operation. I have studied your example on Upload Text File and Image Example in the Not Yet Documented ADF Sample Applications section. I got the file upload part worked but could not get the original file name to populate the name field..i.e. if I upload myFile.txt to the database, the name field will be myFile.txt (not the name enter by user). Is there a way to capture the filename info? or is it possible to do so within ADF framework? I am using ADF/Struts/JSP with ORDDoc data type. Thanks very much.
Bill

Hello Nani,
You need to change any settings in 'FILE' transaction. This transaction is used to set up Logical file paths. ( In general it will be set already for your system).
You can use the following code.
DATA: LC_LOGICAL_FILENAME_EXPSRC LIKE RCGIEDIAL-IEFILE
                                                VALUE 'EHS_IMP_SOURCES'.
DATA:      L_EMERGENCY_FLAG            TYPE C.
DATA:      L_FILE_FORMAT               LIKE FILENAME-FILEFORMAT.
data : X_RCGIEDIAL LIKE RCGIEDIAL occurs 0 with HEADER LINE.
read the default pathname on application server
    CALL FUNCTION 'FILE_GET_NAME'
         EXPORTING
            CLIENT                  = SY-MANDT
              LOGICAL_FILENAME        = LC_LOGICAL_FILENAME_EXPSRC
              OPERATING_SYSTEM        = SY-OPSYS
            parameter_1             = ' '
            PARAMETER_2             = ' '
            USE_PRESENTATION_SERVER = ' '
            WITH_FILE_EXTENSION     = ' '
            USE_BUFFER              = ' '
         IMPORTING
              EMERGENCY_FLAG          = L_EMERGENCY_FLAG
              FILE_FORMAT             = L_FILE_FORMAT
              FILE_NAME               = X_RCGIEDIAL-IEFILE
         EXCEPTIONS
              FILE_NOT_FOUND          = 1
              OTHERS                  = 2.
    write :/ 'file format', L_FILE_FORMAT,
           / 'file name', X_RCGIEDIAL-IEFILE.
Thanks,
Jyothi

Using Resource type in Netweaver 7.1 for file upload

Dear All,
I want to check the file extension and file size before uploading it through a file upload UI element in Web Dynpro 7.1.
How to go about it? And I am using following code for image upload. Is it correct one?

myConnection.connect();
OutputStream out = myConnection.getOutputStream();
int temp = 0;
InputStream text = photoData.read(false);
while((temp=text.read())!=-1)

Kindly help.
