Display file contents

Hi, I am learning servlets, and am trying to write my own simple upload program.
I'm trying to see first whether my code can pick up the contents of the file the user specifies. The form is set to multipart/form-data and uses POST.
Right now I'm using ServletInputStream to print out the information submitted in the request, but instead of printing out the contents of the file, it prints out all the POST parameters, including the file name parameter. It is only the file, theigh, and I want the contents of the file to also be displayed.
Can anybody please help me by describing what I could do to output the contents? Does another type of stream need to be opened to start looking at the file's contents, in addition to just looking at the POST headers and parameters?
Thanks.

Hi Sudhir,
I found an example which does similar to what you are looking for. Unzip the zipped file and you should see two examples.
File Read Customized will help you to read data from file and format into single column.
File Read Customized_multiple line will help you to read data from a file which has multiple rows and columns. Then it updates table on the front panel with new line read.
Please feel free to use it. I am also attaching a sample text file for you to try the example.

How to display file contents on a web page

On unix platform I have created a class that can read the contents of a file and display them to the standard output. But now i want to display these file contents on a web page through jsp. On JSP code I have imported this class and want to assign a record from a file and write it to the screen using html. I think the class needs to be modified in order to return the string record read from a file so that im able to access it from a jsp and assign it to a variable the I can display it on the screen. Can someone help me with these code?

Actually, you mean Linksys. BIG difference there.
Linksys Business Series was accumulated into Cisco Small Business, since it was purpose built for small business, not residential/consumer grade.
The new PVC2300 actually are Cisco branded on the case.
The collateral you seek is protected by the business unit that supplies it, since it was placed on a portal that only Cisco registered partners can access.
As I wrote, I already checked with the BU and they told me thats where it lives and not to hand it out. I cannot override that.
I am not sure there are any secrets in there, but I dont make the rules, sorry.
Do you want to be a Cisco Partner? Sign up and gain access to everything you need to sell Cisco successfully to end customers? If you tell me your geography (city/state/zip, I will have an ICAM call you and help recruit you.....

Display file content in Web Dynpro ABAP

Hello,
we would like to be able to display any file after having uploaded files using FileUpload ui element in a web dynpro abap application.
for microsoft word excel files, the OfficeControl ui element can be used and for pdf documents the InteractiveForm ui element can be used.
for other formats such as '.tif', '.jpg', '.txt'..... we did not find out how to be able to display the file contents
Does anybody know if and how this could be achieved?
Cheers

Chris,
You may be right. Also it requires some configuration in SAP KPro ( document class etc).

Problem in display file content

Hi all,
I've a big problem about using the iFS content display function. My project needs to build up a document search engine and the search result, included the part of the document content, is required to display on the web interface.
Most of the document I searched is PDF and MS word documents. I tried to use the feature in
oracle.ifs.beans.document and get the content out and I tried so many function call there but the result seems not too successful. Following is the function call I tried before.
1/.
Document.filterDocument() ;
Document.getFilteredDocument() ;
As I know, it used the INSO filter to filter the document. The content return is fine for me, but not the format. No matter I put true/false into the Document.filterDocument(), the HTML format will also return instead of plaintext.
I expected to return plaintext in this function so I can customise the format. But why it coudln't be?
I guess there is something wrong about the INSO filter but I have no idea how to configure it....
2/.
Reader a;
a=getContentReader();
Nothing is return using ths function and it ususally reutrn the error message to me. I've no clue....
3/.
InputStream a=null;
a=getContentStream();
It return some strange byte code which is not what I need....
4/.
ContextThemes a=new ContextThemes[50];
generateThemes(false);
a=getThemes();
Maybe it is not relevant function but I tried it.
Nothing I returned to the object arrary.
I will v.v.v. appreciate if someone can help (Hope the supports are not in holiday this moment...)
null

I checked the API of getContentStream() and getContentReader(). it will return the binary data of the document and the readable content will NEVER return to the Reader or InputStream variable.
In addition, even the SimpleTextRenderer with ifsfileSystem.renderAsStream() function is used, the data returned also not the text data of the document. WHat I can get is the properties of that document object, not the useful content in the document.
For the INSO filter Java function filteredContent(), no matter the true or false option chosen in the function, it can only return HTML result. It cannot return the text data!!!!!!
I tried so many solution and it's also not work. I start feel ashame to use Oracle iFS!!! How can the function to be such a unreliable???
HEY, Oracle Support, it is a high time for you to give us a clue.

Finder not displaying file contents

I have dropbox and configured it to show the icon on the tray over the left of my day/time. When I click onto the folder via Finder, I see the folder icon. The "Info" for this folder should allow me to read/write to the folder. However, when I ask to see the contents, I do not get a listing of the files within the folder. I am very frustrated since I have been struggling to resolve this configuration issue out on my own. It is most likely 'user issue' which led me here. However, I am at my ropes end. Can someone tell me how to fix this?
Pete
<Personal Information Edited By Host>

Your original post wat to ask to see what was in that folder. The command I gave was to show that. There is one finder invisible zero-length file in that folder named .com.apple.timemachine.supported which I believe means it can be uses as a TB backup.
If you want to always see these finder invisible files -- everywhere -- then follow the instructions in this article:
Show Hidden Files in Mac OS X
Now you are asking about the folder itself, i.e., what it's access is. I would think you would see that doing Get Info in the finder. But the terminal command to do it is similar to seeing the folder's contents:
ls -lde /Users/petesalcido/Documents/Dropbox/London\ and\ Paris\ Pics\ 2012
Just -lde instead of -la as the ls options (that's an "ell" in the -lde just like the ls).

How to display the content of a file in the portal?

Hey guys, could anyone help?
I just created a page which includes two iView, one is KM Navigation iView to display a certain repository, while the other is for displaying the content of a certain file I click in the navigation iView.
And now the problem is when I click a file in the KM Navigation iView, it will pop up a new window to display it. How can I make it displayed in a fixed iView, which type of this iView should be?

Unable to display the Content of a data file from within another data file in Oracle webcenter portal.

We have a Content Presenter taskflow. This task flow is added to a jspx page. The taskflow fetches the content from the contributor data file. The contributor data file is having a WYSIWYG editor. The content of the WYSIWYG editor is being displayed correctly through the task flow.
We have some links in the WYSIWYG editor. These links again point to some data files. When we click on these links from within the portal, then we are getting a blank page(the url of this blank page is: http://localhost:7101/eWSIBPortal/faces/oracle/webcenter/sitestructure/render.jspx?datasource=UCM%23dDocName%3AWSIB_ARTICLE) and not displaying the content of the data file that we are pointing to from the WYSIWYG editor.
We want to display the content of these data files(which we have pointed from WYSIWYG editor) in-line within the portal.
Please help us to resolve this issue and let us know if any information is required from our end.

Thanks for reply. However, can I use XSQL to dump the formated text to a file? or just can display to client through web browsers?

How to display a file content in view

hi team,
I have files which are already uploaded in SAP. I can read the contents of the file but
I can't find the UI element where I can display the content of the file.
I have heard that IFrame can be used to solve the purpose. But using IFrame I am only
capable to show files which are in MIME objects.
Can anybody give suggestions how to achieve it?

Display blob content as pdf file

Dear Expert,
Currently i'm using oracle apex 3.0.1.
I'm having a problem on displaying blob content (from database table) as pdf file on oracle application express but i'm able to save to download the pdf.
Below is the procedure that i used to display blob content,

l_mime VARCHAR2 (255);
l_length NUMBER;
l_file_name VARCHAR2 (2000);

and oi_idx=pv_index;
exception
when others then
null;
end;
OWA_UTIL.mime_header (NVL (l_mime, 'application/pdf'), FALSE);
HTP.p ('Content-length: ' || l_length);
OWA_UTIL.http_header_close;
WPG_DOCLOAD.download_file (lob_loc);

Displaying doc/txt file contents from portlet

Hi, Can someone pls give a hint on how to do this:
One "book" type content created, with a doc file uploaded. The "publisher " for
this content is set to "sams".
create a content selector which retrieves only this (content) book correctly.
create two portlets. one portlet with above content selector inserted, displays
the publisher name with a hyperlink.
I want the other portlet to display the contents of the file uploaded, for this
publisher. I could establish portlet comm. and could display other properties
of the book such as "author/titile" on the second portlet, but want to know how
to display the uploaded file contents.
thanks much,
-developer

As far as retriving the contents of an uploaded file...
If your XML document has been loaded into Content Management as a binary
property, you have two options:
a) to directly inline the content into the JSP, do something like this:
<cm:getProperty id="node" name="binaryPropertyName" failOnError="true"
isMultiple="false"/>
(This assumes node holds a reference to the Content Management Node
object (perhaps retrieved via a <cm:getNode> tag)
b) to retrieve the value into a script variable for more processing, do
something like this:
<%
Property bodyProp= (Property)node.getProperty("binaryPropertyName");
InputStream in= node.getPropertyBytes( bodyProp.getId() );
// dont forget to close the InputStream
String result=null;
InputStreamReader reader= new InputStreamReader(in);
StringBuffer streamContents= new StringBuffer();
char[] data= new char[8192];
int charsRead;
while ((charsRead = reader.read(data)) > 0 )
streamContents.append(data, 0, charsRead);
result= streamContents.toString();
