Is it possible to reference environment variables in the .properties files?

Here’s what I’d like to do…
In the application.properties files, I tell OPA where the docgen server is via this setting:
# Location of the Document Generation Server
plugin.docgen.server.url=http://bipDev/document-generation-server/
Note that this is the setting from my Dev environment.
Because I have separate DocGen servers for each environment, I have to maintain separate copies of this file for each environment. For example, my Prod file contains this setting:
# Location of the Document Generation Server
plugin.docgen.server.url=http://bipPrd/document-generation-server/
Notice that it’s a very slight changes. I’d like to use something like this instead:
# Location of the Document Generation Server
plugin.docgen.server.url=http://%BIP_SERVER%/document-generation-server/
Obviously, I’d create an environment variable on each server to accommodate the setting. For example, on my Prod machine, I’d create this environment variable:
BIP_SERVER = bipPrd

Unfortunately environment variables cannot be used in the OPA .properties files. The only way to do this is to maintain separate properties for your different environments.

Use environment variables in logging.properties file

is there a way to use environment variables in logging.properties file?
like this -
java.util.logging.FileHandler.pattern = {$MY_BASE_LOG_FOLDER}/myapp1/log/123%g.logdo I have to write a custom logging.properties loader? if yes, then are there any examples on this?

I'm sorry, but don't you think your answer is useless?
Maybe I haven't made my question clear enough. I need to know if java.util.logging recognizes environment variables in logging.properties files.
If it does not, then there should be a well-known class to use instead of standard loader for logging.properties (java api mention one briefly).

Using environment variables in the JAR manifest

Hello,
I need to make a JAR which uses some third party libraries located in the file system, in a path referenced through a environment variable (named for example ENV_VAR). Without using the JAR the application may be started by running:
java -classpath %ENV_VAR%\lib\library1.jar;%ENV_VAR%\lib\library2.jar MyApplication
So what is the syntax to refer to environment variable inside the manifest?

I guess its not possible. If you look at the [Manifest specification|http://java.sun.com/javase/6/docs/technotes/guides/jar/jar.html#JAR%20Manifest] there is nothing that inidcates that environment variables can be used. The classpath attribute is specified as follows:
The value of this attribute specifies the relative URLs of the extensions or libraries that this application or extension needs. URLs are separated by one or more spaces. The application or extension class loader uses the value of this attribute to construct its internal search path.
So actually, if it would be possible the ENV_VAR pathes must be set relative to your application .jar file.
Why not just use a batch that sets up your command line as in the example and runs your app?

How do I use a OS (Windows) Environment Variable in the source path of me ActionScript 3.0 settings

I'm sure this can be done as I know we used something similiar at my old work place, below is an image showing what I am attempting to do.
We used this to create more portable / shareable assets files which when symbols are linking to code, the code was very often in different directories on different machines.
So we had set up environment variables in the OS to point to source directories and then used these variables in the source paths.
As long as everyone had these variables set up then it would all work.
Anyone know the correct way to do this in Flash CC
Thanks in advance!

sinious the problem with doing that is that the changed path gets into the code repository as well, so you wind up with everyone going back and forth changing it to their own value, which is a hassle. If you use relative paths and a standard project setup, then it all "just works" without a problem.
For example, this is the setup I use:
.dev
     .thisProject
          .Flash1
               Flash1.as
               .Flash1
                    Flash1.xfl
               .view
                    .audioAssets
                    .customViews
          .SoundLib
               SoundLib.xfl
          SoundLib.swc
     .bin <swfs are output here
          .xml
     .core
          .control
          .model
          .service
          .view
We have a "base project" that you check out to start a new project (we do heaps of similar work), and the paths are already set up to be relative. Having each project point to its own copy of the core code allows for fine-grained control of which revision you're using--we've even pointed deliberately to old versions or branches on rare occasions.
The bin folder is actually shared with the website repository, which is in a different directory from the Flash source code (in the website, it has a different name). This allows the generated swfs to be easily updated and ensures that the latest XML is being used both for development and on the site.
The "thisProject" folder actually includes a Flash Builder workspace with all the standard shortcuts, etc., already set up. This is primarily because of how the "default path" works when you create a new Flash Pro project in FB. Because we output a level up from the workspace, we hack the .metadata folder every time, but that's a small change.

Is it possible to reference one cell from the value of another?

Is it possible to reference one cell from the value of another e.g.
value of b1 = value of c(value of a1)
So if a1 = 3 then b1 = c3, if a1 = 5 then b1 = c5.

Excellent!
Thanks Wayne. Just saved me many hours and a headache.
Works like a dream.
Thank you for your succinct (and accurate) answer.

How can I pass environment variables to the child process?

How can I pass environment variables to the child process? This is what I tried and it didn't work.
     static public void main (String[] args) throws Exception {
          ProcessBuilder b = new ProcessBuilder("java", "-cp", ".", "Child");
          Map<String, String> map = b.environment();
          map.put("custom.property", "my value");
             b.redirectErrorStream(true);
          Process p = b.start();
          BufferedReader reader = new BufferedReader (new InputStreamReader(p.getInputStream()));
          String line = null;
          while (null != (line = reader.readLine())) {
               System.out.println(line);
     public static void main(String[] args) {
          System.out.println("The value of custom.property is : " + System.getProperty("custom.property"));
     }and the result is:
The value of custom.property is : null

Complete test:
     static public void main (String[] args) throws Exception {
          ProcessBuilder b = new ProcessBuilder("java", "-Dcustom.property=my property value", "-cp", ".", "Child");
          Map<String, String> map = b.environment();
          map.put("custom.property", "my environment value");
             b.redirectErrorStream(true);
          Process p = b.start();
          BufferedReader reader = new BufferedReader (new InputStreamReader(p.getInputStream()));
          String line = null;
          while (null != (line = reader.readLine())) {
               System.out.println(line);
     public static void main(String[] args) {
          System.out.println("Property value of custom.property is : " + System.getProperty("custom.property"));
          System.out.println("Environment value of custom.property is : " + System.getenv("custom.property"));

Can i use a environment variable inside a *.sql file?

Hello,
I want to create a external table.
So i am using the command
create or replace directory abc as 'C:\folder'.... inside a sql file.
Now i want the path "C:\folder" to be dynamic as i am using this path in many other places also inside the sql file.So i thought to create a environment variable and put this value there.I tried using as %PATH% but it gives error..... where %PATH%=C:\folder.
Can i use a environment variable inside a *.sql file?
But how to do that or is there any other way.
Thanks
Swapna

Actually what i want is the path "C:\folder" is not fixed it can be anything which i may not know the user may decide it later. Not supported. A directory object refers to a specific physical location (directory/folder) on a file system. Not a path.
You can work around it by (creating and) using a function (running under a super user schema with authid definer privs). The caller (e.g. schema scott ) calls it with a physical path. E.g. GetDirectoryObject( 'C:\folder\2010\feb\week4' ).
This function determines if there is an existing directory object for the path. If not, it uses a wildcard search to determine if there are any directory objects for parents in the path (e.g. for C:\folder\2010\feb or C:\folder\2010 or C:\folder ).
If it finds a directory object, it interrogates the data dictionary to determine if the caller, schema scott for example, has read/write access on that directory object. If it has, it creates a new directory object and grants the caller read/write access to it. The function then returns the name of the directory object to the caller.
The caller thus do not deal directly with directory objects. The function returns the object name given a physical path as input. Also, only a single base directory needs to be created (e.g. for C:\folder ) and access granted to the schema on it. Any sub-directory in that base directory can now be dynamically accessed by the schema.

How do I use a UNIX environment variable for the path of a file name

We are running Forms 6i over the web. The forms server runs on a UNIX (HP-UX) machine.
I want to read the contents of a file, which is simple enough, using the TEXT_IO package. However, I want to reference a UNIX environment variable that specifies the file path i.e
PROCEDURE get_file IS
in_file Text_IO.File_Type;
linebuf VARCHAR2(1800);
filename VARCHAR2(200);
BEGIN
filename:= '$LOG_DIR/RCAS181.log';
in_file := Text_IO.Fopen(filename, 'r');
.....other stuff
Notice the filename string references my unix env variable '$LOG_DIR'. However, this doesnt work. If I put the full pathname it works fine.
Any suggestions ?

Using custom environment variables in the profile path

Hi,
I've created a custom environment variable that I've setup on two computers and the domain controllers. I want to use this in the profile path in user properties. However when users log in the variable is taken literally rather than being converted
into the value. For example
\\fileserver\share\user\%myenv%.v2 is generated rather than \\fileserver\share\user\envdata.v2
If I add in another built-in variable such as %OS%, that converts properly but any time I use a custom variable Windows just doesn't use it during the logon process. If I open up Explorer and type in the path to my data as it should be it works fine
so Windows is definitely picking up the variable, just not using during the logon process. I can't seem to find a TechNet article that states custom variables can't be used in profile paths.
Has anyone else come across this?
Thanks,
Tim

Hi,
Thanks for your post.
So did you create the environment variable using group policy? If yes, i would suggest you use 'Create' and not 'Update', the variable is then held through reboots.
Please refer to this blog, hope it will be helpful

Setting Oracle environment variable using batch (.bat) file in windows

Hi,
Oracle 9i db
Windows OS
I am in process to create the database (Considered that Oracle9i software is already installed) by running one batch file which consist of all the scripts for the database creation.
But i also want to set the environment variables at MyComputer(right click)>properties>advance>environment, permenently by running the batch (.bat) file
ORACLE_HOME
ORACLE_BASE
ORACLE_SID
So, how can it be done ?
With Regards

Hi,
*@echo off*
set ORACLE_SID=iprsdb
set ORACLE_BASE=C:\oracle
set ORACLE_HOME=C:\oracle\ora92
call C:\install_bkp\test_env_var.bat
echo Test Successfull.
Above mentioned is the code written in the batch (.bat) file
In that i have also called another .bat file which test the env. variable values which is as below:
c:\>test_env.bat
===================

Test Successfull.
But when i checked at MyComputer(right click)>properties>advance>environment variables
there, I saw none of the entries from the above, why so ?

Within JBuilder, Reading Environment Variable From a BATCH File

Hi ppl:
Following my scenario without JBuilder. I would like to be able to do the same with JBuilder, so that I can run my application from within.
1. In the DOS window, I run a config.bat file that sets up a whole bunch of environment variables and then calls another script file that sets up another whole bunch to set up environment for a third party API (C++ based).
2. My application uses native methods to call the third party API which uses the environment variables set in step 1.
I know how to set the environment varialbes in JBuilder (Project Parameters, VM). However, I don't know how I can call a batch file that does the same. I don't want to set up the third party variables in JBuilder manually, since the script that sets them up checks on a few things to customize the environment.
I also know how to run a batch file from JBuilder, but that does not set the environment for the application. It seems like the batch file is run in a separate process.
Any ideas?
Kamran

It seems like the batch file is run in a separate process.Yes, it is. That's a design feature of Windows. The environment variables that a process creates are available to any subprocess, but when the process ends, the environment variables vanish. That's because they are part of the process, not global variables as you might wish.
So that's why your non-JBuilder scenario works; your C++ program is running in a subprocess of the process that defined the environment variables. And your JBuilder scenario doesn't work because the batch file it runs is in a process whose parent process is Windows, not JBuilder.

Showing environment variables on the logon screen?

Is it possible to use a variable in the name of other variables?

Trying to avoid a long post; is there some command in Java that would allow a variable to be read before the rest of the statement it is in?
For example, using a pair "@" to encapsulate a variable with the mystery command I'm looking for:
*public class Example {*
*public static void main (String[] args) {*
Char variable = "A";
int @variable@_Status = 0;
So that this application would create an integer named "A_Status" and assign it a value of 0. Obviously, I'm not looking to be told that "int A_Status = 0" is the best way to do that, I'd like "variable" to be able to be defined by input or change somehow in the code. I have a gut feeling that this is impossible due to the compiler, but I'd like a more professional opinion. Anyone?

The variable "name" is a lot less important than you think. In fact, when your code is compiled, the computer doesn't care one jot about the name of the variable.
You should not worry about trying to do this, but rather should tell us the reason why you would even want this. If we knew that, we could show you a better way, guaranteed.

Reference texts in messages.en.properties file

Hi,
I've got a peculiar issue. I'm trying to access a variable/property/reference
in my VM file like below:
<p class="warning">${FailureWarning}</p>
And FailureWarning is defined in messages.en.properties file as
# Custom Warning Messages
FailureWarning=Session status fail, additional data entry not permitted
However, when rendered on the UI, the message is contained with square
brackets. This does not happen with any other text (if I were to change the
value for FailureWarning).
[Session status fail, additional data entry not permitted]
Does the text hold a special meaning in OPA/Velocity rendering?
Regards,
Ajay

Each message is treated like any other key and value in Velocity. A value will consist of either a string *or* a comma-separated list of strings (see Velocity - Developer's Guide). What you have defined is a list consisting of 2 strings - "Session status fail" and " additional data entry not provided", so Velocity will render these values within square brackets to indicate this is a list of strings. You need to escape the comma with a preceding '\' to have Velocity treat this as a single string:
# Custom Warning Messages
FailureWarning=Session status fail\, additional data entry not permitted
You will see the escaped comma in the values for case-saved-label, NullTemplateError and NoActiveSessionError.
Hope this helps,
Brad
