Re: reading a property file

[Raghupathy, Gurumoorthy]

using the ServletContext object like

 

 

  context.getRealPath("/");

 

this will give you c:\....\....\webapps\myapp\ ( the start directory of your context )

 

then get the file seperator ( using system.getProperty(file.seperator)  ) then add it to the string

 

 

OK I will right the code.

 

String file = new String("file_name");

Sring path  = new String("");

path = context.getRealPath("/");

String fs = System.getProperty( file.seperator );

 

path  = new String ( path + fs + "WEB-INF" + fs + "classes" + fs + file_name ) ;

 

 

Now path will have the file name .....

Subject: reading a property file

hello,
 
   i have a situation here:

   i want that i can change my property file dynamically without
   restarting Tomcat.

   i tried implementing it using the suggestion that was given to me by
   some of the people here which is to place the property file on the
   WEB-INF/classes directory and read it using this statement:

      Properties oProp = new Properties();
      oProp.load(this.getClass().getResourceAsStream
                         ("/CommandServer.properties")';

    this works fine. but the problem is when i change the property
    file dynamically while tomcat is running my changes doesn't take
    effect. the same default value was read.

    so, what i did was i make use of the File class to read the property
    file and implement it like this:

         File ofile = File ("..\\webapps\\myapp\\WEB-INF\\classes\\
                                com\\test\\MyProperty.properties");
         FileInputStream oIn = new FileInputStream(oFile);
         Properties oProp = new Properties();
         oProp.load(oIn);

    this also works, and i am able to change my property file dynamically.

    my question is, how do i place my property file so that when i read
    it using File class i don't have to include the
    "..\\webapps\\myapp\\WEB-INF\\classes" extra path...instead just read
    it directory from my package directory structure.

    is there a way Tomcat can read my property file that way?

 thanks in advance
