Reading values from properties file

Hi All,
I am in need of a help from you all.I have a login.jsp which gets username and password as user input and checks in the servlet that if it was admin and admin it will take to index.jsp and if it was other than admin and other users it should take to index1.jsp.For now i am using an if condition to check the values and to dispatch the request.I need to use a properties file for this and need to check by getting the values from the properties file.And also it should check for each entry in properties file and if it finds any matches it should take to the corresponding page.
Please help me in achieving this.
Thanks,
laxmi

How can i read comments from properties file in the right order??

Hello
I want to build a console that read a properties file and print to the screen the property name, property value and property description and the developer can change the name or the value or the description of the property and update the property file.
But the problem in using the properties class that it doesn�t read the comment and not save the properties in their order so I can�t couple description and name of the property.
Does any one know any utility that do the job or know how to solve the reading the comments problem???
Thank you a lot?

sorry but i dont understand how the solution of using
a dot ( property_key.description ) helping me to
solve the problem?
please try to explain it agin.
thank youYou wrote:

So i'm as developer imagine that somebody edit properties in GUI or console. So you have 3 text fields: property name, property value, and propety description. Then developer save edit changes, then text fields maped to properties file and:
text field "property name" and text field "property value" construct property:
name=valuetext field "property name" adding ".description" and text field "property description" construct property:
name.description=descriptionFor one described property, you will have put two properties.
Thanks!

Read value from text file to JTextField

Hi,
I think this is the right place to post this. Although maybe it is not it could be classed as I/O issues?
I have a JFrame with a JTextField which requires the user to enter a value. When they click a JButton "OK". It writes the value to a text file and closes the frame using FileWriter. If they click clear button it writes the value "" to the file. What I want to do is when the frame opens it reads the value from the text file. I have been trying to use FileReader but have not been able to write the code correctly. Any help would be greatly appreciated.
Thanks

File f = yourfile;
BufferedReader br = new BufferedReader(new FileReader(f));
String value = br.readLine();Alex.

I have done some coding on it but dont seem to be getting the desired results. I want to take these values and put them in a 2D array.. but its not doing it. Can you see any mistakes i have done please ?

                         b++;

Yes thats because its part of larger code.. it is just a method within my code.
but your right about the catch but so yeah sorry i missed it when i copied pasted. I ve also added you a main method.

How to read values from Property file into BPEL process local variable?

I would like to use a Property file with some parameters e.g.
<myparm1>12345</myparm1>
How can I read from a BPEL process such a Property file and assign it into e.g. local variable "intparm1"?
Where (in which directory) should I put this XML Property file to have it always available for reading?
Peter

Hi,
You can also use
ora:readFile( ) function as follow :
ora:readFile(xml file location (ex. "file:///D:\\SOA\\FileAdapters\\readFile\\test\\test.xml"),xsd file location (ex."file:///D:\\SOA\\FileAdapters\\readFile\\test\\test.xsd"))
inside the assign activity and assign this to the variable you want.

Reading value from a text file

in query like select * from tbl1 a where a.lotid = values from text file ?
kindly advise
tks & rdgs

Following the example Elyo gave:
CREATE TABLE MyTable(line VARCHAR2(4000)) ORGANIZATION EXTERNAL (

location ('test.txt')
1- use, eg.: fields terminated by ',' to indicate your separator character.
I'm not sure I understand the second question.

How to read from properties file

Hi,
I am using JSR 168.
while creating a new portlet, a folder gets created with the name as "portlet". Under which is resource package and <PortletName>Bundle.java.
pls tell me how to read from .properties file.
waiting eagerly for some reply
Thanks & Regards,
HP

I think i have mixed it up :)
I have looked at it again and believe you are using regular JSP portlets.
Can you tell what you want to achieve by reading .properties file. Are you meaning the preferences of the portlet or what exactly are you trying to do?
Reading propertie files is easy:
// Read properties file.
Properties properties = new Properties();
try {
properties.load(new FileInputStream("filename.properties"));
String myKey = properties.getProperty("yourKey");
} catch (IOException e) {

Reading Design values from readback file

Hi All,
I am trying to understand the process of reading back design signal values from readback file.
I have both the .ll file and the readback.bin file
To get the readback file, I executed the below command:
% readback_hw_device [current_hw_device] -readback_file <filename.rbd> -bin_file <filename.bin>
Now, I want to know the command or process to read the design signal values from this .bin file? Is there any command provided by Xilinx or anything else that I can do to read the signal values?
Rgds
Sapan

Hi Syed,
Thanks for the reply. It was actually my own started thread. I had few questions unanswered from that post:
Question:
The procedure for readback that I am following here is based on the ug908-vivado programming and debugging.
I first uploaded the image on FPGA and then I executed the following commands in Vivado Hardware Manager
% create_hw_bitstream -hw_device [current_hw_device] -mask fpga.msk fpga.bit
% verify_hw_devices [current_hw_device] #### For readback verify
readback_hw_device [current_hw_device] -readback_file <filename.rbd> -bin_file <filename.bin> #####for readback capture
This looks a little different from the one suggested in your document. Can you please confirm if my steps are correct?
Using the above procedure, I did not have to explicitly send readback commands to the FPGA using JTAG as mentioned in doc:
http://www.xilinx.com/support/documentation/sw_manuals/xilinx2015_1/ug908-vivado-programming-debugging.pdf
However the other doc http://www.xilinx.com/support/documentation/application_notes/xapp1230-configuration-readback-capture.pdf mentions sending commands to the device in order to be able to do a readback.
So I am a little confused which one is correct?
Also which document will give the words per frame information for FPGA XC7VX485TFFG1761?

Issue in reading multiple time properties file

Use Case:
I have a page in which i have to show some Outage Messages on page. So I have configured outage message in properties files. This message should me rendered each time when it finds that properties file in class path or it finds the values w.r.t their keys.
So what I decide that I shall write java method and call this method on Loading the page but here what happen is that whenever that page is load each time that reader file will call , that will create memory leak .
So, anyone help me on this. What will be the best approach for that reading multiple times properties file?
I will be grateful for any help you can provide
Thanks

Hi,
have a bean at applicationScope, somewhat like this
import java.util.HashMap;
public class ApplnProperties {
    private HashMap _propMap;
    public HashMap getPropMap() {
        if(_propMap == null){
            //read the properties file and populate _propMap
        return _propMap;
}here we put condition _propMap == null so it would be called only once during application lifecycle.
and on page you can refer the prop map like following
#{beanName.propMap['KEY1']}Regards,

Reading data from flat file Using TEXT_IO

Dear Gurus
I already posted this question but this time i need some other changes .....Sorry for that ..
I am using 10G forms and using TEXT_IO for reading data from flat file ..
My data is like this :-

How can i do ?
Initially my requirement was to read only 2 or 3 columns so i did like this ...

I have to check the file :-
Validation are 1st line should start from 0 else it should raise an error and insert that error into one table .
The for 2nd line also same thing ..it should start from 9 else it should raise an error and insert that error into one table .
Then the 3rd line should start from 1 else it should raise an error and insert that error into one table .
After that i have to do a validation like i will read the 1st line 2nd column .. It should be like this BP-V1 else raise an error and insert that error to a table . Then i will check the 3rd column which is 20100928 , it should be YYYYMMDD format else same thing ERROR.
Then like this for all columns i have different validation .......
Then it will check for the 2nd line 3rd column . this is an account no .1st i will check it should be 12 char else ERROR .Then I will check that what user has imputed in the form.Like for example User putted 111111111 then i will check with this 000111111111 which is there in the 2nd line . I have to add 000 before that Account no which user imputed .
Then the lines which is starting from 1 , i have to take all the 2nd column for all the lines which is starting from 1 and i have to do a sum . After that i have to compare that sum with the value in the 1st lines ( Starting from 0) 6th column . It should be same else ERROR ...
Then same way i have to count all the lines which is starting from 1 . Then i have to compare with the 7th column of 1st line . It should be same . Here in this file it should be 9.

Read data from Excel file and diaplay in Webdynpro

Hi all,
I need some help. I have a Excel file with set of name, phonenumbers . I want to know how to display the data using Webdynpro. Could some one help me. help is appreciated and I promise to award points for right answer.
Thank you
Maruti

<b>Hi
i can explain you to read data from Excel file
First You have to download the jxl.jar file. You can get this file from the Below site
</b><a href="http://www.andykhan.com/jexcelapi/download.html">jexcelapi jar</a>
It will be in Compressed Fromat So Unzip it to get the Contents
After Unzipping The File You will get a Folder (jexcelapi/jxl.jar)
Now in NWDS open web dynpro explorer, Right Click Your Project, a popup menu will appear and in that click Properties
You will get window displaying your Project Properties
On Left Side of the window You Will Find "Java Build Path"
Click That "Java Build Path" and you will get 4 Tabs Showing ( Source,Projects,Libraries,Order and Export)
Click Libraries Tab
You will find options many options buttons
In that click the Button "Add External Jars"
You will get Window in order to fecth the jxl.jar file from the location you had stored
After selecting the jxl.jar i will get displayed and click ok
Now Open Navigator
Open Your Project
You will find Lib folder
Copy the jxl.jar to that lib folder
Note : You cannot Read the Content from the excel file directly
First You Have to copy that file to the Server,
And from the Server you can get the file absolute path
With the absolute path you can read the contents of the Excel file
You have to save the Excel file as .xls Format and Not as xlsx format i will not accept that...
You have Upload the Excel file from the Server Using the File Upload UI Element
This Coding will extract 3 columns from the Xls File

Reading Data from CSV file

Hi Guys,
I am trying to read data from a CSV file character by character. Whats the best way to do this? Any examples around?
Thanks
tzaf

Does this mean your file will have multiple lines? And each line would indicate a new record? If so, you should use the BufferedReader and take in each line as a String. Then you can use the StringTokenizer to separate your string into tokens using the comma as your delimiter. From there you can convert the string tokens into whatever form you like, but by default they are already in String form. To make it an Integer I'd use Integer.parseInt().
I will show you some code on how to get the values from your file using the BufferedReader and the StringTokenizer but what you do with those values afterwards I'm going to leave up to you.
File csvfile = new File("myfile.csv");
byte[] fileBuf = new byte[1024];     // buffer for file data
int bytesRead = 0;               // number of bytes read
try
     BufferedReader fileIn = new BufferedReader( new FileReader( csvfile ));
     PrintStream out = new PrintStream( System.out );
     String readLine;     // stores a line from the file as a string
     while( (readLine = fileIn.readLine()) != null )
          StringTokenizer tokens = new StringTokenizer( readLine, ",", false);
          // false means you don't want to count the commas, only the values
          while( tokens.hasMoreTokens() )
               String aValue = tokens.nextToken();
               // ... do what you want with the value
               // ... change to Integer or whatever
               out.println(aValue); // Printing the value to the screen
     fileIn.close();
}Good luck,
