Using apache FileUpLoad?

Hello
I am to trying write a small web application which allows the user to upload files to there account.
And rather than storing them on a database, to store the files on the server and a link to the file on the database.
I have seen examples how to obtain the files using the apache FileUpLoad tool. But wondered if anyone could advise, how to store the files on the server.
So each file has a unique filename, and stop new files from writing over existing stored files. Is there are some way I could name them on the server as File1, File2 File3.... and keep a record of the current number?
Thanks

Use java.io.FileOutputStream to store them in a common directory.

Hi there,

are you calling the writeFile method trying to pass a String instead of a File object?

File upload using apache Commons FileUpload problem

Hi All,
I have used Commons FileUpload for uploading files from windows to unix machine. I'm able to upload files but I have a problem about the contents of file copied in unix. When i upload files few files containing special characters are not copied correctly in unix instead ascii codes are getting copied/written. Seems to be a problem with character encoding.
For example symbol "�" is not getting copied correctly in unix. So as new line character to. If anyone has faced such issues kindly provide few pointers on this. Appreciate your guidance.
Thanks,
-Aj

Thanks for the reply.
I'm using the Commons FileUpload class "FileItem" which holds the filestream data and using function
code snippet of file upload
ServletFileUpload servletFileUpload = new ServletFileUpload(new DiskFileItemFactory());
List fileItemsList = servletFileUpload.parseRequest(request);
Iterator it = fileItemsList.iterator();
while (it.hasNext())
     FileItem fileItemTemp = (FileItem)it.next();
     File saveToFile = new File("newFile");
      fileItem.write(saveToFile ); // write fileItem data to saveToFile.
} FileItem object takes care of writing data to disk.No idea,how it does internally.
Thanks,

Apache FileUpload - what version of Tomcat can run it?

Hi. I'm trying to use the Apache Commons FileUpload component (http://commons.apache.org/fileupload). It works fine on my local PC (Java 1.5.0_15) but fails on the Unix server running Tomcat 4.1.29 and Java 1.4.2_12-b03. I've got the latest version of the upload component in the WEB-INF/lib folder. It throws this error (included only the top section; there are more, similar errors having to do with each fileupload component call). Do I need an older version of the upload component to work with this version of Tomcat and Java? If so, which version do I need to download? The oldest I could find dated to 2003. Thanks.
The server encountered an internal error () that prevented it from fulfilling this request.

Apache FileUpload - what version of Tomcat can run it?First of all, why don't you ask Apache specific questions at the Apache mailinglist?
Regarding to your actual problem: those are just ordinary compilation errors which are complaining that the mentioned packages and classes aren't available in the classpath. The solution is obvious: add the mentioned packages and classes (or in this case, the JAR file(s) with it) to the classpath during compile time and you're fine.

Can't use Jakarta FileUpload in JSF?

I am trying to use Jakarta FileUpload for uploading a file to server database. It works fine in JSP. However, when I migrate the system to JSF, it does not work again. I can find that the request type seems that is different. In JSP, the request received by Servlet is SRTServletRequest. In JSF, it is MultiPartExternalContextImpl$MultiPartServletRequestWrapper.
When I trace the fileupload class in JSF, the jakarta fileupload cannot parse the request to List object and finally, fail to get the file(s).
My question is, can I parse the "JSF request" to get the file(s)? If not, how can I change the request type?
I know that there is a fileupload package in JSF, however, can it upload the file by inputstream (memory in server) only, rather than need to upload the file at a server (second storage in server) first?
Thanks for any reply.

I use file upload of myFaces extensions with Sun JSF RI.
I did the following steps:
1) Added: Tomahawk.jar to "lib" folder.
2) Added myFaces apache filter to "web.xml". Take a look here: http://myfaces.apache.org/tomahawk/extensionsFilter.html.
3) Added upload field to the form:
for example:
<t:inputFileUpload
id="themeFile"
value="#{themeBean.themeFile}"
storage="file"
required="true"
validator="#{themeBean.validateThemeFileName}"
style="width:100%" />
4) Add to your Bean the following member (with setter and getter):
private UploadedFile themeFile;
5) On the "save" action of the form add the following code in order to extract the uploaded file:
InputStream in = new BufferedInputStream(
themeFile.getInputStream()); // This is the uploaded file
BufferedOutputStream os =
new BufferedOutputStream(new FileOutputStream(newFile)); // newFile is the file you would like to store on the server
byte[] data = new byte[BUFFER_SIZE];
int readSize;
while ((readSize = in.read(data, 0, BUFFER_SIZE)) != -1)
os.write(data, 0, readSize);
in.close();
os.close();
Hope it helps . . .

Problem in upload PDF file using Apache HttpClient3.1

Hi:
I am using Apache HttpClient 3.1 to upload pdf image from a STANDALONE java application to remote server (Weblogic9.1). Here are some questions:
1) Do i have to use multipartpost method? (I am uploading pdf image one by one)
2) The pdf image is added to request as:
HttpClient client = new HttpClient();
PostMethod method = new PostMethod("myServletUrl");
method.getParams().setParameter(HttpMethodParams.RETRY_HANDLER,
new DefaultHttpMethodRetryHandler(3, false));
InputStreamRequestEntity entity = new InputStreamRequestEntity(new FileInputStream(file), "application/pdf");
method.setRequestEntity(entity);
method.setRequestHeader("Content-type", entity.getContentType());
int statusCode = client.executeMethod(method);
3) On server side, a servlet will save the posted pdf image as (Apache FileUpload is not used here):
InputStream is = req.getInputStream();
saveFile(is, fileName); // write this input stream to file.
The above steps 2 and 3 will create a pdf file on remote server with MUCH REDUCED size. Any idea what's the problem? content-type problem?
4) An working example link will be great.
thanks

Dunno, but as this is a client side issue, the solution, if there is one will lie in the HTML / javaScript.
If you dont get an answer in here, have google for an HTML solution, which you can then write out in your jsp.

SSO with a website using Apache Httpclient form post

Hi ,
I am trying to obtain, SS0 with a website, that accepts the user information via post.
I tried using app Integrator, but the website sends a cookie in first request, and redirects to another URL. App Integrator is only catching the first response.
Thus i tried implementing this Form post using Apache HTTPClient class inside the Abstractportacomponent, as shown..
The login is taking place. But, When i click on any link on the page, It is redirecting to the login page again, I am wondering where should i give the Cookie, so the portal request will include that cookie in its subsequent requests, so that i wont be prompted for login agian..
thank you,
chiranjeevi.

Hi Manish,
first, welcome on SDN! About your question:
The URL iView in SP9++ has been reported quite instable from different sides (just do a look on "URL iView" within this forum). The alternative for the aim you have is to use the good "old" application integrator iView, which behaves very stable and will do what you want without hesitating...
Also see URL iView and HTTP System - SSO to web app
Hope it helps

Maximum file size using htmlb:fileUpload

Hello Gurus,
in a bsp application we are using htmlb:fileUpload. It was possible to upload a 43 MB file without problem. But our maximum file size is about 220 MB. We made a test with a 190 MB file. After we hit the post button, the browser disconnects immediately (without timedelay) with the message: page cannot be displayed.
for me it looks like we hit some restriction.
any idears how to manage the 220 MB file in the browser beside splitting it into smaller files would be greatly appreciated.
thx a lot in advance and regards from
Michael

Hello again,
could it be this parameter which is for the limitation responsible ?
icm/HTTP/max_request_size_KB = 102400

Chinese Charcters in PDF using Apache FOP

Hi,
I am creating a PDF using Apache FOP.
This data contains Chinese characters.
On APEX 3.1, I couldn't contain Chinese characters in PDF.
On APEX 3.2, is it possible?
Is there any way that I don't have to use BI Publisher?
Please advise on this.
Thanks

Providing security to the PDF file using apache FOP in java

I am working on PDF file generation using Apache FOP, I have security concerns which are
1. PDF file will be placed in a folder after generation and that should not be copied to other locations.
2. PDF file should only have an option print nothing else. The save/save as options should never be enabled.
3. PDF expiry date is required, so that PDF file will get expire after duration.

HI,
I did that too, with too much experiments.
Code snippet for reference.
PdfReader reader = new PdfReader(getOutputFilePath());
PdfStamper stamper = new PdfStamper(reader, new FileOutputStream("my-new-file.pdf"));
stamper.setDuration(1,1);
int permissions = PdfWriter.HideMenubar & PdfWriter.HideToolbar & PdfWriter.HideWindowUI & ~( PdfWriter.AllowCopy | PdfWriter.AllowModifyAnnotations | PdfWriter.AllowFillIn | PdfWriter.AllowAssembly | PdfWriter.AllowModifyContents | PdfWriter.AllowScreenReaders);
stamper.setEncryption(null, null,
permissions, PdfWriter.STRENGTH40BITS);
stamper.setFormFlattening(true);
System.out.println(stamper.getMoreInfo());
stamper.close();
I am able to disable the save button, but I am unable to disable the save as option.
It would be great help, if you can give some inputs on this.

Enterprise portal access using reverse proxy using Apache and webdispatcher

Hi Guys,
As requirement, we need to give solution to customer about Reverse proxy scenario. I am new to this part.
What we have think of to use Apache and Web dispatcher.
I tried to search documents and found some sdn links also but still i am not comfortable to go about.
Need suggestion and document if anyone has used so far.reverse proxy.
As basis person, we need to do all ( Apache installation, Apache configuration, Web dispatcher installation and configuration, integration with EP.)
It will helpful to me if i can get Apache installation, Apache configuration part and integration with EP, or web dispatcher, configuration etc.
Thanks,
Deepak

We used Netscaler for Reverse Proxy implementation and can assure you that network team performed most of the set ups. This was on EP 7.01.
From BASIS stand point it would be primarily Web Dispatcher Configuration.
Also refer the links I specified in another thread. There are several scenarios discussed there -

Obtaining client certificate in servlet using apache + tomcat

Hi,
I'm porting a webapplication from Javawebserver to Apache/1.3.6 (Win32) mod_jk mod_ssl/2.2.6 OpenSSL/0.9.2b
The application needs to get the client certificate hash code.
Using Javawebserver I used
request.getAttribute ("javax.net.ssl.cipher_suite");
request.getAttribute("javax.net.ssl.peer_certificates");
etc
How do I set up the apache webserver so that I can read the client certificate and what is the attribute called?
I've tried this in the httpd.conf:
SSLOptions +ExportCertData
And the attribute:
"SSL_CLIENT_CERT"
Like it says in the Tomcat documentation.
I'm not sure if I need to set up Tomcat as well..
Any help would be greatly appriciated!
Sincerely,
AM Hjemaas

Yup use ajp13 not ajp12 or mod_webapp
refer to http://www.galatea.com/flashguides/apache-tomcat-24-win32.xml on setting up..
THIS IS IMPORTANT!!!
use Apache mod_jk.dll diretive:
JkEnvVar Apache_Env_Var FORWARD_ALIAS
this will send a apache environment variable (http://myapache/cgi-bin/printenv.pl to see whats available) to Tomcat
JkEnvVar SSL_CLIENT_CERT SSL_CLIENT_CERT
Then in Tomcat servlet use request.getAttribute("SSL_CLIENT_CERT") to get the cert in PEM format
Hope this helps

My client (Netscape browser) are making SSL connection to Apache.
I would use SSL3 from client to Apache then read the client certificate from
WebLogic (in back-end) servlet to check the user's attribute from ldap
server. Could you tell me if there is some example of keeping client
certificate from front-end web server to WebLogic servlet?
Thanks,

This forum is meant for general Java questions. Your question is better asked on a Apache mailing list:

But before posting there, I suggest you first read u[p on how to ask a question on a public forum or mailing list, because if you post what you now just posted here on a mailing list, I doubt that you'll get answered.
