File upload JSP

Yet again the issue of file upload...?:|
I am trying to use a file upload as part of my screenflow.
I besically have 2 jsp files. jsp file upload code and the supporting HTML.
I created 2 "interactive component calls", connected with a transition and in the 1st one I call one JSP and in the 2nd one the other JSP.
My action on my HTML is action="fileupload.jsp" (my upload code file) I try changing it to action="<f:postResults />" but that didnt work
Then I changed my action to "<f:postResults fowardUrl="fileupload.jsp"/> I got an error on that too.
Anyone can help with that issue? I am besically tring to do a simple file upload from my sub-process.
Thank You
Lilach

Uploading a file using jsp and com.oreilly.servlet lib package

Hi,
Looks like you are missing a file from the classpath. Make sure servlet.jar is available in your classpath. Ordinarily files in <tomcat_home>/lib directory should be added automatically. You need to check why it hasn't been added in your case. A good place to start would be the bat files in the bin directory viz startup.bat, catalina.bat etc.

How to Upload a file in JSP ( doc, txt ) as an attachment

I want to upload a file using JSP. I tried Jason's Multipart program, but it is creating some problem. Pls suggest me the alternate. How to write a code. Is there any bean available for free download. Pls. help me.

I have successfully used Multipart classes from Oreilly. I believe that's the same one you are referring to. I have implemented my Upload using a servlet though. If you can post what exactly is your trouble using that code, I will be glad to help you with it.

JSP : latest JSTL, File Upload from web form Client to Server Question!

I understand that within a JSP, It is possible to read a file from the Client by opening a Stream somehow.
How do I code, within jsp/servlet (non tag) java code inside <% %>
blocks, WITHOUT openening a new connection to the URL, an InputStream from a client web browser form, from a file upload coded using
<input type="file" name="file1"/> ?
I have previously achieved this quite simply with a FileInputStream
with the previous version of JSTL.
How may I do this with the latest version of JSTL, with this index.jsp?
-with a simple text file.
-with a Binary file (with DataInputStream)?

<form name="form1" method="POST" enctype="multipart/form-data">
<input name="file1" type="file"/>
<input name="submit1" type="submit" value="Submit" action="index.jsp"/>
</form>

and run this in an index.jsp, use browse to select my text file, and click SUBMIT.
I can use:
InputStreamReader reader = new InputStreamReader(new DataInputStream(request.getInputStream()))
BufferedReader bufferedReader = new BufferedReader(reader);
bufferedReader.readLine();...
However, these is some HTML/POST related content around what multiple readLine();
calls return.
Is there an easy way, like using "${param.file1}",
aside from [http://commons.apache.org/fileupload/|http://commons.apache.org/fileupload/],
maybe using servlet style code, to get the File contents from a remote Client,
to the remote Server servlet engine, AVOIDING ANY SUPERFLUOUS CONTENT,
using version 1.12 of the JSTL, JSP 2.0,Tomcat 6?
Just politely, yes, no, and how?

How to get full path of a file uploaded using file control on a jsp ?

Hi all...
I have a jsp on which i am using a file element (input type="file") to upload files present on the physical file system.. Thats working fine.. But i want to retrieve the full path of the file uploaded for further computation.
What are the possible ways which can give me the full path ?? (e.g. "D:\data\text\Output.txt" )
Thanks all for attending the question..
Regards
Prasad

Some browsers send the full path. Some do not.
You can not affect this in any way shape or form.
All you can count on receiving is a filename - no path information.
So you will have to have some other way for the user to pass along this information.
If they are uploading to a "remote web site" they could specify a folder to put the uploaded file in.
You could classify it and put all image files in "images" and all script files in "scripts" etc etc by default, and let the user deal with it in their own HTML.
Hope this helps,

Display uploaded file on JSP page

Hi All,
I want to display uploaded file in JSP.
Initially I am displaying File Name after saving the file & click on edit link.
i.e on JSP Page I have File Upload component & save button.With that save button I am saving my file to databse.
So when I click on edit link I am getting that file name from Databse then I am displaying it.
But now I want to display uploaded file name on JSP page before saving to databse.i.e I will have browse & Upload button.When I click on browse button I will open window from where I will select file.
This is working fine as,<x:inputFileUpload id="uploadfile" value="#{errorLotBean.file}" storage="file"></x:inputFileUpload>
But when I click on upload button that uploaded file should be displyed there only.Can anyone please tell me how to do this ?
Thanks
Sandip

Thanks a lot Siefert,
I tried the way mentioned in URL.
But what if I want to display all uploaded file on my screen.
i.e. If user click on browse & select File A then click on upload button.
(Here the File A will be displayed) with code
<h:outputtext value="#{benaName.file.name}"
But what if after displaying File A if user decide to upload another file File B.
How to display that ?
with <h:outputtext value="#{benaName.file.name}" its dispalying one file only.
Thanks
Sandip

File upload, download using ADF UIX and not JSP

I have examples for the file upload, download using JSP
But I want to use ADF UIX. Look and feel in this is impressing and I want to use this. Any one have example for this.
Users will select a file from their desktop
This will be stored into the database (Any document. Word, Excel)
When they query the records then the UIX column need to give a hyperlink. Clicking on the link should prompt to download the file to the local system

Sure, I use the Apache Commons File Upload package, so that is what I will discuss here ( [Commons File Upload|http://commons.apache.org/fileupload/] ).
The Commons File Upload uses instances of ProgressListener to receive upload progress status. So first create a simple class that implements ProgressListener:
public class ProgressListenerImpl implements ProgressListener {
    private int percent = 0;
    public int getPercentComplete() {
        return percent;
    public void update(long pBytesRead, long pContentLength, int pItems) {
        if (pContentLength > -1) { //content length is known;
            percent = (new Long((pBytesRead / pContentLength) * 100)).intValue();
}So in your Servlet that handles file upload you will need to create an instance of this ProgressListenerImpl, register it as a listener and store it in the session:
ServletFileUpload upload = new ServletFileUpload();
ProgressListenerImpl listener = new ProgressListenerImpl();
upload.setProgressListener(listener);
request.getSession().setAttribute("ProgressListener", listener);
...Now create another servlet that will retrieve the ProgressListenerImpl, get the percent complete and write it back (how you actually write it back is up to you, could be text, an XML file, a JSON object, up to you):
ProgressListenerImpl listener = (ProgressListenerImpl) request.getSession().getAttribute("ProgressListener");
response.getWriter().println("" + listener.getPercentComplete());
...Then your XMLHttpRequest object will call this second servlet and read the string returned as the percent complete.

File upload and download using jsp/servlets

How to upload any file to the server using jsp/servlets. . Help me out

You can also try the Jenkov HTTP Multipart File Upload. It's a servlet filter that is easy to add to your web-project. After adding it, you can access both request parameters and the uploaded files easily. It's more transparent than Apache Commons File Upload. There is sufficient documentation to get you started, and there is a forum if you have any questions.
Jenkov HTTP Multipart File Upload is available under the Apache license, meaning its free to use.

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 ;-)

URGENT.........File Upload using Servlets and jsp

I am a new servlet programmer.......
iam using tomcat server......
can any one pls help in writing code for file upload using servlets and jsp without using multipart class or any other class like that....
Please URGENT..

Slow down! "Urgent" is from your perspective alone. I, myself, am not troubled or worried in the least.
hi ugniss
thanks for ur reply....sorry i was not
y i was not asked not to use multipart class or any
other class like that...is there any other
possibility to do file uploading from jsp to
servlet...
Just as an aside, a JSP is a Servlet. But even if I move beyond that, the question does not make sense. If you want a "JSP to upload to a Servlet", then simply do so in memory. You are still (likely) within the same scope of a given request. However, if instead you are referring to a JSP that is displayed on a browser, then really you are talking about HTML, which is what the browser will receive. And since you are now talking about a browser, your only real, viable option is a multi-part file upload. So, it is either server or it is browser. And either way, the question leads to very established options, as outlined above.
the main concept is.. in the browser the user selects
a particular file and clicks the button upload..after
clicking upload the jsp should sent the file to the
servlet in streams...there the servlet gets in and
saves in a server location........this is wat i hav
to do...
Okay. So, after reading my previous (redundant) paragraph, we have arrived at the crux of the issue. You have a JSP that will be output as HTML to a client (browser) which you want to upload content to your server (handled by a Servlet). So, you are now stuck again with multi-part. The requirement to not use multi-part is non-sensical. You can overcome it, say, if you write your own applet or standalone Swing client. However, if your users are invoking this functionality from a browser, you are limited by the options that W3C has provided you. Use multi-part.
is there aby possibilty to do this.....can any one
pls help....Take the advice to download and review Jakarta Commons FileUpload. Inform your management that their requirement makes no technical sense. Research on your own. There are dozens of examples (and tutorials) on file upload using multi-part. Embrace it. Live it. Love it.

Uploading jsp files

Hello:
I'm new to Mac OS X server, but an old hand at unix based systems. My problem is simple: I am unable to upload JSP files using WebDAV. I can upload pretty much anything else, but get an error when trying to copy up JSPs. Is there an ACL or something that needs to be set?
Any help would be much appreciated. Thanks in advance.

To answer my own question -- since JSP files are mapped to Tomcat through Apache using mod_jk (at least in my case), and since files are transferred using Apache when using webdav, every request for a jsp transfer is passed on to Tomcat, and Tomcat had no idea what to do with the request. Tomcat does have a webdav client built in, but not installed.
Fortunately, the solution is fairly simple.
Disable webdav on the site in question using the Server Admin tool. Create another web site in Server Admin, with a name like "webdav.mydomain.com". Enable Webdav for this site. Unlike the version of the site that is "live", do not connect this version to tomcat using mod_jk. Create a new realm, with permissions set as follows:
Everone: None
You: Browse and read/write WebDav
This is fairly important if you want to protect the contents of your jsp files. Assuming that you've made the changes to the domain name record, you should now be able to connect to http://webdav.yourdomain.com and transfer jsp files back and forth as you wish.
