Impossible to open and read a file

Hi,
I use ejb and servlet in ECLIPSE with JBOSS 5 under windows XP.
I have under ECLIPSE
- a web dynamic project "cnam"
   +cnam
         +build
               +classes
         +src
                +servlet
         +WebContent
                +WEB-INF- an EJB project "EJB"
   +EJB
        +build
              +classes
        +ejbModule
              +ejbBeans- a project "EJBClient" and a project "cnamEAR" that are automaticaly created by ECLIPSE when "cnam" and "EJB" are defined.
I added the project "EJB" in the java build path of the project "cnam"
however I want to read a property file from a servlet of the "cnam" project and from a session bean of the "EJB" project.
in = new FileInputSream("classpath:constantes.properties");
j ai essaye aussi
in = new FileInputSream("constantes.properties");The problem is that I don't know where I should place the file "constantes.properties", in which ECLIPSE project and in which folder so that it can be recognized. I tried all possibilities, but nothing is working.
I have an example of another project using SPRING where the location of a property file is defined by "classpath:hibernate.properties" and where the file "hibernate.properties" is placed in WEB-INF/classes folder and it works. But in my case it doen't work.
All is about classpath. Does anybody can explain me about classpath ? is classpath relative to the operating system ? is it relative to java ? is it relative to to ECLIPSE ? or is there a relation with the ".ear" file ?
(By the way, the ".ear file is defined as follow :
{code}
+cnamEAR.ear
+EJB.jar
+EJBClient.jar
+cnam.war
{code}
Knowing that it works with "classpath:hibernate.properties", in the scope of SPRING, I am sure that there is a possibility in my case.
Thank you for your help

Hi,
Do I have to put it in the classes directory... ?Yes. But it is not mandatory.
You may store your properties file inside the package of your application.
For example, if you want your properties file in the servlet folder, your ResourceBundle statement must be this way :
ResourceBundle rb = ResourceBundle.getBundle("servlet.constantes"); xflamant wrote:On the other hand, what can I do after I have fetched my ResourceBundle to read my properties ?
Can you be more explicit please ? Thank youFor example, if you want to retrieve a property called "URL" in your file, all you have to do is :
String url = rb.getString("URL");
Also, in the properties file, URL property should be declared this way :
URL=http://something.com/and_so_on There must be no space between URL and =

How to open and read binary files?

How do I open and read Binary files?

Did you look on The Unarchiver's web site where it has a link to older versions? http://theunarchiver.googlecode.com/files/TheUnarchiver3.2_legacy.zip
The best thing to do is ask your friends what programs they used to produce these files, or at least what format files they are producing. Otherwise it's like being shown a car and given a bundle of 200 keys with no idea to which one to use, or even if any of them work with that car.
Using The Unarchiver will likely not do anything because it too will not know what format files are involved, and they may not even been in an archived format. If they sent you a Word file without telling you (a favorite of Windows users to do -- it drives me crazy when they could have just sent them in plain text), The Unarchiver won't open them. If it's a picture file then using Hexedit will just show you a bunch of unintelligible stuff as shown in an earlier post, though you may see a line of text providing a hint.
As I said earlier, often .bin may be an executable program which needs another program to actually interpret it. That's what Java is trying to do. Still, it may think it can execute the file, but it is highly unlikely somebody would send you an executable program (and if they did I would not trust it). For all you know it may be a Windows virus.

Can you use PDF Pack to open and read PDF files?

Can you use PDF Pack to open and read PDF files?

Hi Keith,
PDF Pack is a conversion tool which would convert PDF to different formats and vice versa. It cannot be used for reading PDFs.
If you want to open and read PDF file you can use Adobe Reader.
You can download Adobe Reader from below mentioned link.

How to open and read many files from a directory and store contents in 2D array?

I want to make a VI that opens and reads the data from various files contained in a directory (200 files each with 2 columns) and store these in a single 2D array. For file number 1 I want to store the data from both columns in the 2D array, but for files 2 to 200 I only want to store the second column of each file. Can someone please help?

Hi Nadav,
Thanks for your help. I have followed your instructions but i cannot get it to work. I used the LIST DIRECTORY to list the files in the directory - that works. However, how do I read each of the 200 files using READ FROM SPREADSHEET FILE without me having to manually select each of the 200 files? So, if I use LIST DIRECTORY to list all 200 files in an array, how do I get each of these to open and store the data in a 2D array? Here is what I have done (File called read_files.VI) Could you please help me? Thank you very much in advance.

"Error 1 when trying to open and read datalog file from several subVi's

So, I've been coding up this model based controller and have hit a snag:
The program starts and opens a datalog file and passes the refnum to two loops.
At a regular time interval (every 2 minutes), one loop (that's iterating once per second) writes the current information to a datalog file.
Meanwhile, another loop (that's iterating continuously) checks to see if the file is big enough to support training of the model, if it is, then the training process begins. Once this happens a period of recent information is read from the file. Initially, this read would fail and return 0 data. However, this problem was fixed by passing in the data file path rather then the refnum and having the vi open,
read, and close the data file. With the path, the vi was able to read all the data. However, still in the same loop, another vi downstream tries to read the file and returns error code 1, and no data is read. I tried passing that vi the path and seeing if it made any difference to open, read and close the file. But even then the read failed (with error code 1).
I don't understand why it can read in one vi and not the other!
Does anyone know what is going on here? It seems that semaphores would probably solve the problem, but would prefer a simpler solution. Thank you very much.

Try passing the data to the continuous loop through a LV2-style global. That way you are only access the file in one place. But then that begs the question, if the data is passed internally, do you really need the file at all?

How to open and read an external file in Dashboard widget?

I am new to Dashboard widgets and also Javascript. I have written a widget that needs to open and read a file on the local file system. I have searched a lot and have not found any documentation or reference on the internet as to how to do this.
I know it can be done since there is a checkbox in the widget attributes that says "Allow External File Access".
can anyone help me out here?
Thanks

You need to define the AllowFileAccessOutsideOfWidget key to Yes.
You also need to define the AllowFullAccess key.
You may also need to define the AllowSystem key (to Yes of course).

How to open and read pdf and micrsoft word (.doc) files or documents

My problem is how to use my BB 9800 software version 6.0.0.546 to read/view pdf files and microsoft office documents. I have also bought documents to go from online and have installed it on my phone, but whenever i try to open it I receive a message that it is incompactible. Any help will be greatly appreciated.

Hi, Sammy.
Why not install a 3rd party PDF reader and Word Doc reader to help open and read pdf and micrsoft word (.doc) files or documents? You can google it and select one whose way of processing is simple and fast to help you with the related converting work. It will be better if it is totally manual and can be customized by users according to our own favors. Remember to check its free trial package first if possible. I hope you success. Good luck.

Hi... I would like to purchase a Tablet Sony Xperia Z 2 10.1 (the last one of the Z series) and I was told that Adobe does not support Sony anymore.... I need to be able to open and read Adobe PDF files and I would like to know if this tablet can still use Flash Player...
Is there anyo who can help me with this? I asked in the shop and I was told "yes of course" , but when I contacted Sony directly I was advised to check with Adobe as apparently in the recent months Adobe and Sony haven't been getting along anymore...

You may be mixing up two entirely different Adobe products.
1. Adobe Flash Player. Needed to view web pages designed with Flash. Not needed to view PDF files. Not available for Android (not just Sony).
2. Adobe Reader. Reads PDF files. However, the Android can also read most PDF files without needing Adobe Reader.

For sideloaded content the nook pulls the metadata from ePub file itself. I would suggest looking at a program like Sigil or Calibre that will let you edit the metadata in the book to make it appear like you want.
For the PDF vs ePub - No, that's the way PDFs work (think of them as graphics, not text), wheres ePubs are Web Pages - so no you can't them to behave exactly alike without converting the files.

FYI TDMS open and read on empty file gives no error's out

I found that if you 'open' an empty (0 byte) file using TDMS open, you will not get any error messages when you open it, nor when you call functions such as "Get properties" or "List content", also no error when you close the TDMS file.
If the file is non-empty, but not a valid TDMS file, TDMS open returns an error.
I would have expected that I would get an error or a warning at least when trying to read a non-existant property or group, if not by the open function itself?!
The 2013 snippet below creates a 1-byte or empty file in the local user temporary folder, closes the file, then attempts to open and read it as a TDMS file. The temporary file is deleted afterwards.
If the file is empty, NO errors or warnings occur at any point. If the file is not empty, it fails on the TDMS open. (Note the sequence structure is because the path out of the tdms close is invalid if the tdms open failed.
This could conceivably cause an issue if your program does not do additional fault checking to catch existing but empty files. (Which of course shouldn't ever happen, but in some situations it could happen.)

Hooovahh
I asked to list the channels in a named group. If that named group did not exist, I would think that should at least be a warning, but I could see how it should not be an error, it was just unexpected to me that reading a non existant group (in an empty file) did not indicate any issues at all. To me, 'error out' should give a warning or an error if something unexpected happened, but I may just have stricter opinion on something that by nature is very philosophical and open for debate. (And there are always tradeoffs, overt checks and bounds in a function obviously leads to overhead, and TDMS is optimized for performance, so that may be one reason it is the way it is.)
(This situation came up for me because when a file is first created, we datetime tag it and write a bunch of other meta-data to the file, then later (and over time) we add the spectrum goup + data. [Edit] actually, in the old code, if the file existed, it was assumed to have been setup correctly. so if the group exists, the old code assumed all the meta data has already been written [end edit].. One of the many fixes possible, I'll rely on the 'found' boolean output of the parameter read instead of relying on the error/warning. If the datetime tag is found, the code will asume the file exists and has been filled with the meta data I expect.)

What tool is used to open and read UCS tech support files

Hello,
Due to internal Infosec policies, I need to open and read UCS tech supoort files that I generate prior to sending them to Cisco TAC. Can someone tell me what tool I can use to accomplish this task? Thanks.

Good to hear.
Are you intending to blank out all the proprietary info? IPs, Hostnames etc?
Suggest an advanced editor such as ultraEdit which can find and replace any private information.

Open and Save Excel Files

Hi All,
I need code of How to open and save excel file in local system in Oracle forms.
With Regards,
Chandra Shekhar

Hello Chandra,
Webutil can be used to achieve this functionality.
STEPS TO FOLLOW
================
1. Install and configure Webutil following instructions in the webutil manual
and the readme file.
2. Create a form with a block Eg. DEPT
3. Create a button, and in that button put the following code -
DECLARE
application Client_OLE2.Obj_Type;
workbooks Client_OLE2.Obj_Type;
workbook Client_OLE2.Obj_Type;
worksheets Client_OLE2.Obj_Type;
worksheet Client_OLE2.Obj_Type;
args Client_OLE2.List_Type;
cell ole2.Obj_Type;
j INTEGER;
k INTEGER;
BEGIN
application := Client_OLE2.create_obj('Excel.Application');
workbooks := Client_OLE2.Get_Obj_Property(application, 'Workbooks');
workbook := Client_OLE2.Invoke_Obj(workbooks, 'Add');
worksheets := Client_OLE2.Get_Obj_Property(workbook, 'Worksheets');
worksheet := Client_OLE2.Invoke_Obj(worksheets, 'Add');
go_block('dept');
first_record;
j:=1;
k:=1;
while :system.last_record = 'FALSE'
loop
for k in 1..3 /* DEPT has 3 columns */
loop
If not name_in(:system.cursor_item) is NULL Then
args:=Client_OLE2.create_arglist;
Client_OLE2.add_arg(args, j);
Client_OLE2.add_arg(args, k);
cell:=Client_OLE2.get_obj_property(worksheet, 'Cells', args);
Client_OLE2.destroy_arglist(args);
Client_OLE2.set_property(cell, 'Value', name_in(:system.cursor_item));
Client_OLE2.release_obj(cell);
End If;
next_item;
end loop;
j:=j+1;
next_record;
end loop;
/* For the last record */
for k in 1..3
loop
If not name_in(:system.cursor_item) is NULL Then
args:=Client_OLE2.create_arglist;
Client_OLE2.add_arg(args, j);
Client_OLE2.add_arg(args, k);
cell:=Client_OLE2.get_obj_property(worksheet, 'Cells', args);
Client_OLE2.destroy_arglist(args);
Client_OLE2.set_property(cell, 'Value', name_in(:system.cursor_item));
Client_OLE2.release_obj(cell);
End If;
next_item;
end loop;
Client_OLE2.Release_Obj(worksheet);
Client_OLE2.Release_Obj(worksheets);
/* Save the Excel file created */
args := Client_OLE2.Create_Arglist;
Client_OLE2.Add_Arg(args,'d:\test.xls');
Client_OLE2.Invoke(workbook, 'SaveAs', args);
Client_OLE2.Destroy_Arglist(args);
/* release workbook */
Client_OLE2.Release_Obj(workbook);
Client_OLE2.Release_Obj(workbooks);
/* Release application */
Client_OLE2.Invoke(application, 'Quit');
Client_OLE2.Release_Obj(application);
END;
4. Save the form and compile it.
5. Run the form.
6. Execute the query in the block.
7. Click on the button.
8. An excel file will be created in the d:\ directory by the name test.xls.
Kind regards,
Alex
