File upload using applet and opera

Hello All
I am uploading file using applet it is working file in the IE and Mozilla firefox but it doesn't work in the opera , The client is sending request but server doesn't respond it , why it should be happening with opera only . i am using jre1.6 , applet is loading successfully . But while uploading file response from server is not occur.
please post u r comments.

On the server side, you'll probably want to grab a 3rd party library for handling the multipart request.
This one is very popular and has sample code in its documentation that should get you going pretty quickly.
http://jakarta.apache.org/commons/fileupload
For the client side, this question would probably do better in an applet forum.
One obstacle you'll need to deal with is the applet sandbox. By default, Applets have no access to the client machine's file system. You'll either need a signed applet that will prompt the user for permissions to access files or you'll need your clients to install a security policy that allows your applets to do this.
Again, these details will be better worked out in an applet forum.

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.

File upload using uiXML and Struts

Hi,
I am using Struts as my controller component with uiXML for the UI. I need to add file upload functionality to one of my pages. After a bit of trial-and-error, I figured out that the following code in my uiXML sets me in the right direction -
<struts:form name="myForm" method="post" beanName="myFormBean" usesUpload="true" destination="/try/SaveTry.do">
When the "destination" attribute is not specified, the Struts action does not get the file. However, with the changes above, the uploaded file now reaches my Struts action, which does the necessary processing and the Struts controller forwards the control to the next page according to its logic.
However, at this point, I see the following on the browser -
java.io.EOFException

I tried to specify my own file upload manager (which does nothing) and also tried to subclass the UIXPageBroker to return false in shouldHandleUploadFile() and null in decodeMultipartRequest(), all to no avail.
Could somebody please let me know if I am missing something? Why is the AbstractPageBroker still kicking in after my file upload has been processed?
Thanks in advance,
Smarto

Thanks Kennethkawamoto2, now i knew the reason, but still i am getting error for crossdomain.xml , when moving flash on production.
I am putting it as below,
Security.loadPolicyFile('xmlsocket://ipaddress:80/crossdomain.xml');
can anybody help?
much appreciated,

File Upload using struts and jsp

Hi,
Anybody have sample coding for uploading files into the database using struts and jsp.
Thanking you in advance for providing the sample coding.
Veena

Hi Veena,
In Strutsconfig.xml you have to configure data sources like this
**************strutsconfig.xml******
<data-sources>
<data-source
type="org.apache.common.dbcp.BasicDataSource">
<set-property property="driverClassName"
vlaue="oracle.jdbc.driver.OracleDriver"/>
<set-property property="url" vlaue="jdbcracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521))(CONNECT_DATA=(SID =ORCL)))"/>

<set-property property="username"
vlaue="scott"/>
<set-property property="password"
vlaue="tiger"/>
</data-source>
</data-sources>
Now here is how to get data source
public class LookupAction extends Action
public Double getQuote(String symbol,
HttpServletRequest request)
throws Exception
Double price=null;
Connection conn=null;
Statement stmt=null;
ResultSet rs=null;
DataSource dataSource=null;
try
dataSource = getDataSource(request);
conn= dataSource.getConnection();
stmt= conn.createStatement();
rs= stmt.executeQuery("select * from stocks where" + "symbol='" + symbol +"'");
if (rs.next())
=======================
After you can use the coding what I posted earlier.
For that you need to create a table with attachment as a CLOB col.
then with prepared statement I am setting value .
Plz try your self every thing ok you can get that.
all the best
bye

File upload using Servlets and Weblogic

Hi,
I need to write a servlet that can upload a .doc file to a folder on the server. Can someone please let me know abot the code i need to write, as i am a novice in servlets.
Thanks in advance
buddy0303

Another, simpler (we think), such package is Jenkov HTTP Multipart File Upload. It's a servlet filter which can work in front of both servlets and JSP's. The servlet filter parses the uploaded file and stores it temporarily on the servers disk. When the servlet or JSP executes afterwards, it can obtain all the information about the file, from the request attributes. There is a decent manual for HTTP Multipart File Upload on the website.
Just search for "Jenkov HTTP Multipart" on Google and you'll find it. HTTP Multipart is free, open source, Apache Licsense.

File upload using Struts and hidden field

Hi,
I have seen many examples to upload file using <html:file> tag. But my request is how to upload file using hidden form field and ActionServlet.
I want to upload image without using Browse button options, through hidden field i will set the image file path and will upload to server using ActionForm.
Please help me friends to solve this new issue,
regards,'
dhaya.

That's not possible.
If it was, it would be a huge security hole. What about mailicious websites with hidden field which points to "c:/my documents/passwords.txt" and automatically submits the form using Javascript?
Consider a signed applet instead. If it is unsigned then you'll get a security popup "Do you trust this software?" anyway.

File Upload using Flex/ColdFusion. 2044 error

I am looking for a little more clarity around the file upload using Flex and Cold Fusion. When I run this using my server I get Error #2044: Unhandled IOErrorEvent:. text=Error #2038: File I/O Error.
I did create a regular cfform and had it use my ColdFusion upload form and that worked fine, so I feel good about the upload form. I am starting to think there is a permission error with the Flash Player writing to the folder. When this is ran, it will show the file being 100% loaded but the complete event is never triggered. I put alerts to see where it hits and 100 does show at the same time as my error message. The complete alert never shows. I also put an alert in my cfm page and it never reaches that page to hit it. Whether I use an absolute URL or relative path. I have also tried the urlrequestmethod.post and nothing changed. Thanks in advance. BTW. I am using Flex 3.

Presumably you need to add a result handler to your request.

File Uploader Java Applet cannot be run

I have a website that I need to upload PDFs to, but since ugrading to Lion, I cannot do it any more. I have downloaded the separte Java app, but it still does not work.
This is the error message I get:
File Uploader Java Applet cannot be run. Make sure that Java is installed on your PC and Java applets are permitted in browser settings. Use this link to download and install appropriate version of Java:

Thank you etresoft - that did not solve the problem. However, I did fix it by changing something in Java Preferences (which is located in the Utilities Folder).
I first deleted the cache files as you suggested in the Network tab. Then I quit and restarted Firefox. I still got the same error message when I tried to upload.
Then, I went back into Java Preferences and checked the box, "Enable Appplet Plug-in and Webstart Applications" located in the General Tab. I then quit and restarted Firefox. Now I am able to upload documents as I could before Lion.
Thank you!!

File uploads using jQuery with jquery.fileupload.js fails in Firefox over SSL

Please see the link below where I originally posted the question.
http://stackoverflow.com/questions/27792614/file-uploads-using-jquery-with-jquery-fileupload-js-fails-in-firefox-over-ssl

Thanks. In my estimation that is exactly the issue. But that doesn't help with a resolution.
The actual file size: 945,991 bytes
If Firefox is miscalculating the length (in Safari/Chrome 945991 and 946241 in Firefox), then Firefox is reporting erroneously and should be raised as a bug in Firefox, would you agree?

File uploads using servlets to oracle8i database

Try the jason hunter book Java Servlet Programming for a very good description or the web site hosted by o'reilly
www.servlets.com
Has a very neat java class for decoding multipart mime encoded files (the upload stream from the browser). Seems to accomodate most of the differing browsers intretation of the standard.
Note to Oracle: This should really be handled by the servlet engine as an Oracle extension. Where the servlet engine strips the mime encoding out before the servlet is called placing the decoded file in an associated extension call. ie: cast the request to an Oracle request object which has file uploaded method.

Re user tip: How can I import a homemade DVD into iMovie for editing? - I've followed instructions so far so good, until I get to "You can then FILE/EXPORT USING QUICKTIME and choose Apple Intermediate Codec as your video codec. " How do I do that?

Re AppleMan 1958 excellent user tip: How can I import a homemade DVD into iMovie for editing? -
I've followed instructions with success until "You can then FILE/EXPORT USING QUICKTIME and choose Apple Intermediate Codec as your video codec. " How do I do that?
I installed MGEG Streamclip 193b8 and used their utility to install quicktimempeg2 and got a message stating it was successfully installed. (I'm on latest Maverick 10.9.2 on iMac) Then I dragged the VIDEO_TS file from my home DVD into the streamclip app. It asked which of 4 files to use, and I selected the first one. Streamclip played the video with the sound. so far so good. but now I cannot figure how to use quicktime player 10.3 to export this vob file out of streamclip.

Thank you for your quick reply and for clearing up my confusion. I'm exporting the first section now. I choose the smallest size, 3x4 but I'd prefer to go higher as this DVD was originally a VHS home movie. I'm wondering if after three conversions (VHS,->DVD->MPEG) the resolution will be so poor as to not support a larger size frame? If it can, what size should I select when I export?

I cannot import my AVCHD files by using log and transfer. I can see all the files, but when I add the file to import que it doesnt work, the status is a red and says that its no data. I have tried with different cards and different cardreaders, but it is still the same. Why?!

Please give us more specific information -
What make/model camcorder are you using?
Are you absolutely certain this is AVCHD video? Tell us more about the video settings you used in the camcorder (eg, frame size, frame rate, quality level)
Why are you attempting Log & Transfer from a card reader instead of from your camcorder? Have you tried doing Log & Transfer from your camcorder?
Are the SD cards straight from the camcorder, unaltered, or are you just using the cards as storage?
Are you using FCE 4.0 or FCE 4.0.1?

Download and Upload using applet

hi everyone,
i tried to develop an applet that can handle upload and download file from server to client and vice versa.
is there anyone can help me?
Please help.
thank you for replies.

You need to sign your applet and the user needs to trust this signature in order for the
applet to read from the local filesystem and or connect to a server other than the one the
applet came from.

Reliable file upload using JDev, AS and other

Hello,
I'm not sure this is the right place to post this message, sorry if I was wrong to put it here.
The question is our company is developing software, for active data exchange with other systems. We decided to exchange in xml format, by means of both web services and web interface (so that exchange could happen both automatically and on user request). We use JDev to develop, Oracle AS to deploy application. Systems we exchange can use various platforms, in fact, it doesn't matter what exactly they use. The question is we need a reliable way to exchange large (sometimes small, but can be 1Gb or, for example, 10Gb) files, maybe with appropriate security, so that it could continue if something happens with network connection.
One simple decision is to have a web service that accepts, for example, 100K at a time, and another service continuously calls it until file is transfered. So it can check response code. But are there better decisions? I think, there are libraries or smth like this?
Thanks in advance, believe, it's a right place to get help.

Another, simpler (we think), such package is Jenkov HTTP Multipart File Upload. It's a servlet filter which can work in front of both servlets and JSP's. The servlet filter parses the uploaded file and stores it temporarily on the servers disk. When the servlet or JSP executes afterwards, it can obtain all the information about the file, from the request attributes. There is a decent manual for HTTP Multipart File Upload on the website.
Just search for "Jenkov HTTP Multipart" on Google and you'll find it. HTTP Multipart is free, open source, Apache Licsense.

File upload using commons-upload-file and tomcat 5.5

Hi,
This is my first post and I hope that I post it at the right place.
I'm trying to upload a file using commons-upload-file and tomcat 5.5.
Is there a way to prevent submitting a big file, If I detect that the file being uploaded exceed a limit that I have fixed ?
i.e. I check the request length, if it's bigger than 1meg I cancel the whole thing and the big file is not transferred.
The problem that I get at the moment is that it seems that the file is transferred even if I close request inputstream or response outputstream. Any help would be appreciated !
Thank you
Redgy

Well here is a snippet of my code:
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        long maxSize = 50000;
        boolean isMultipart = ServletFileUpload.isMultipartContent(request);
        if(isMultipart){
            // Create a new file upload handler
            ServletFileUpload upload = new ServletFileUpload();
            upload.setSizeMax(maxSize);
            try {
                upload.parseRequest(request);
            } catch (FileUploadException ex) {
                ex.printStackTrace();
                request.getInputStream().close();
                response.getWriter().print("blah");
                response.sendError(response.SC_INTERNAL_SERVER_ERROR);
                response.getOutputStream().close();
    }If the file is bigger than 50kb, it Throws the FileUploadException.
But whatever I do, It seems that there is still a connection between my browser and tomcat.. any clue ?
thanks
