How to use properties file

Hi,
I want to use properties file in my application. I have kept properties file inside a directory called properties which is inside myProject(which is the parent directory of my project) i.e "myProject/properties".
My java file where i want to call this properties file is inside the myProject/WEB-INF/src/java.
How can i call the properties file from myProject/WEB-INF/src/java/PropertyReader.java
I wrote java program in myProject/WEB-INF/src/java/PropertyReader.java like:::::
ResourceBundle resBun = ResourceBundle.getBundle("Test", Locale.getDefault()); // Test.properties is inside myProject/properties
resBun..getString("name");
After running the program i am getting the following errors:::::
Exception in thread "main" java.util.MissingResourceException: Can't find bundle for base name Test, locale en_US
at java.util.ResourceBundle.throwMissingResourceException(ResourceBundle.java:836)
at java.util.ResourceBundle.getBundleImpl(ResourceBundle.java:805)
at java.util.ResourceBundle.getBundle(ResourceBundle.java:576)
at PropertiesReader.main(PropertiesReader.java:4)
What is the issue? How to use properties file?
Waiting for reply.
Thanks

Still getting same exception. As you explained i tried like the below:::
1. I am using ant as build tool.
2. My properties file is for database configuration
My properties file is::
database.properties (inside myProject/properties)
JDBCDriver=org.gjt.mm.mysql.Driver
JDBCConnectionURL=jdbc:mysql://pmdbmysql:3306/bandwidthshaper?user=admin&password=admin
My java package structure is
WEB-INF/src/java
WEB-INF/src/classes
For build WEB-INF is the base directory and build.xml is inside the src directory
In my build.xml i wrote the following lines for compilation::
          <target name="compile" >
               <javac srcdir="src" destdir="src/classes" debug="true" debuglevel="lines,vars,source">
                    <classpath refid="class.path"/>
               </javac>
<copy todir = "src/classes" >
<fileset dir = "../properties" />
</copy>
               <jar jarfile="lib/${project.jar.file}" basedir="src/classes"/>
          </target>
I am copying properties file to the classes directory.
Now in java file which is inside /WEB-INF/src/java, I wrote::
try {
Properties programProps = new Properties();
InputStream is = getClass().getResourceAsStream("/database.properties");
if(is == null)
throw new IllegalStateException("Properties file missing ");
programProps.load(is);
System.out.println("driver name::::::: "+programProps.getProperty("JDBCDriver"));
is.close();
} catch(Exception e) {
e.printStackTrace();
After compilation in my classes directory i am getting database.properties file and my java file with package.
At the time of running i am getting "java.lang.IllegalStateException: Properties file missing"
Now tell me where is the fault. Why again i am getting exception.
Thanks

So I donot know how to deploy a .properties file to the server and how to access this file in my Java code?

Hi,
1) put .properties file to your packege under src\packages folder (src\packages\com\sdn\properties\jco.properties)
2) load property:
     final InputStream is = getClass().getClassLoader().getResourceAsStream("com/sdn/properties/jco.properties");
     final Properties properties = new Properties();
     try
          properties.load(is);
     catch(Exception e)
          wdComponentAPI.getMessageManager().reportException(new WDNonFatalException(e), false);

Hi,
Go to the navigator view...select src\Components\<ComponentName> and create create a .properties file.
You can read the configuration file in your webdynpro app as follows
IWDConfiguration configuration =
      WDConfiguration.getConfigurationByName(
        wdComponentAPI.getDeployableObjectPart(),
        "<<>>");

Use properties file in Struts framework

I develop a websit with struts, web ap is tomcat5.0, and I have a conf.properties file
this file is different from ApplicationResource.properties, conf.properties in the /MySite/conf/ directory, not in src directory
When I Use the conf.properties file in a Common Java Class that not extends any super class
it will occur a FileNotFoundException exception
How to make it
public class Environment
     private static Properties prop = new Properties();
     private static FileInputStream in = null;
     public static String getVariable(String key)
          try
               in = new FileInputStream(new File("\\conf\\config.properties"));
               prop.load(in);
               return prop.getProperty(key, null);
          catch (Exception e)
               e.printStackTrace();
               return null;
          finally
               try
                    in.close();
               catch(Exception e)
                    e.printStackTrace();
     }

Your class cannot find the file in the location tht u have given. The path (\\conf\\config.properties) is relative to the location where your source (Environment class) is kept.
Try to hard code the path & see if your source can find the prop file ...

Use properties file out of EAR

HI All,
Generally we create an EAR file with all the property files embedded in it. Here the problem is as and when we change the property files we need to build a new ear file and redeploy to J2EE stack.
Is there any way that this properties file is out of EAR application and changes done to the property file reflects in EAR? So that, no need to redeploy the application again and again. Means dynamic reflecting of property changes to already deployed EAR application. How it can be done?
Actually this is our client requirement also...
Hope am clear.
Regards,
Satish.

Hi,
There are ways to achieve this.
I guess you can try following.
You can define properties file in another project (like java project) and then include that project as a reference in your EAR application.

When to use properties file

On navigating into any web application there wil be some .proeprties file (build.proeprties, applicationResources.properties etc..) and some .xml files(web.xml, struts-config.xml). Why .properties file why not all in XML ??

The question should be: why XML and why not a properties file? XML is lots of overhead for simple tasks.

ECATT - How use external file/new variant for input data

Good day,
I want to use an eCATT created by someone else for another request. I want to be able to specify my new input data based on the new request WITHOUT generating a new Transport. Same thing as I'm doing for the CATT ... the CATT is transported but only the input data change depending on the request without generating any transport.
How I build my new input file and how to use it? I tried to download my variant but the only possible format is XML and it's very hard to build a new file based on my request.
Thanks for your help.
Simon

Hi,
Can you tell me how you are generating the xml file. My guess is you are downloading the Test Script/ Test Configuration. In that case it creates an xml file.
As mentioned by Ajay, In Test Configurator / Test Data - you can create the internal variant first, i.e assuming you have already created parameters.. On the top, you have a download button "Download Variant". This creates a .txt file. You can open the file in excell and edit it.
For the next test, you can select external variant and give the modified file path name.
Let me know if this helps.

How use pdf files

Hi;
I have the following process : I receive via FTP of the pdf files which are stored on a directory of my server (Tomcat + JOnas). This directory is outwards of the deployment directory of JOnas (work directory) and the pdf files are not inside of war file but uploaded directly on the directory.
I must realized a JSP which display to user these pdf files. So my question how implemented this JSP in using external directory ?
regards;

Don't write a JSP to do that. You will find it almost impossible to keep extra whitespace from being sent to the client along with the PDF, and that will make the PDF unusable at the client.
Instead write a servlet that reads from the external directory and copies the file to the response. You'll have to use (I think) application/pdf as the content type, and there are sometimes other browser-related problems with PDFs.

Any Ideas whet to do with this?Ensure the .bin file is executable and your Linux environment has access to the net. The bin will run a network-based install.
These .bin files are usually self-extracting, and a brief description of this is at http://www.cyberciti.biz/faq/howto-unix-command-run-execute-bin-files-in-linux/ (which can be found using http://lmgtfy.com/?q=linux+.bin+files)
There are forums that deal specifically in installing WebLogic Server, and these forums are available by going to the "Forum Home" link at the top of the page and scrolling down. Curious - why are you asking DBAs who deal primarily with Oracle Database Server and not middleware?

Using property files into an EAR Project? How?

Hi there,
I'm pretty new to j2ee development, so i hope i'm not asking a silly question.
So what I have done / wanna do:
- I created a ejb module project with several ejbs and several java classes in it
- I created an ear application project to deploy the ejb module project
- I am succesfully deploying my ear on my j2ee server
So after all, I want to load different properties of some java classes through properties files (*.properties). How do I do that in this situation? Is there a way to use properties files altough the whole ejb project (containing the properties files) is packed into one file (the ear file)?
I hope someone can help me an I'm pleased for every message
Thank you all.
Regards
Daniel
