Getting system-variable folder

Hi,
I have a little problem, I hope somebody can help me.
If I have a system-variable (on WindowsXP), e.g. JBOSS_HOME, that points to the root folder of my JBoss installation, how can I get access in a Java-program to it, so I can access a file, that is placed in a folder like that:
JBOSS_HOME/folder1/folder2/file.txt
when there is:
JBOSS_HOME = C:/jboss
Thanks for your help

You can't really get at ... actuall the phrase is "Environment variables" directly.
The equivalent in java is system properties, accessed through System.getProperty() but you have to define them on the java command line.
However in windows you always have to have a command line stored somewhere anyway. You should be able to modify it to something like:
javaw -Djboss.home=%JBOSS_HOME% -jar myapp.jar
This will often be in the application shortcut properties. Then you can get the value with System.getProperty("jboss.home");

Getting system Variables

Hi. I'm creating jsp page, which uses ssl connection. I want to print information of user logged into page, but I can't understand - how to get system variables in JSP page?
directory httpd.conf file:
<Files ~ "\.(cgi|shtml|php)$">
SSLOptions StdEnvVars ExportCertData
</Files>
# ExportCertData
When this option is enabled, additional CGI/SSI environment variables are created: SSL_SERVER_CERT, SSL_CLIENT_CERT and SSL_CLIENT_CERT_CHAINn (with n = 0,1,2,..). These contain the PEM-encoded X.509 Certificates of server and client for the current HTTPS connection and can be used by CGI scripts for deeper Certificate checking. Additionally all other certificates of the client certificate chain are provided, too. This bloats up the environment a little bit which is why you have to use this option to enable it on demand.
For example, I want to get SSL_CLIENT_CERT variable. How should I do it?

Did you tried
System.getProperty("");
Just check if it works for you.

How can i get system variable using java

Hi,
I just want to know how can i get system variables using java code.
for example i want to get the the date for today or i want to get the number of processes that's running.
Thanks alot

Hi,
I just want to know how can i get system variables
using java code.
for example i want to get the the date for today or i
want to get the number of processes that's running.
Thanks alotSome generic "system variables" are available though Java, usually through the System class.
Date today = new Date();
is instantiated with the current date and time.
Other system values, like environment values, should be passed to java through the command line (-D option) by setting system properties.
Finally, platform specific values like the number of processes running will have to be written in platform specific code and executed by JNI (java native interface).
Java is platform or system agnostic. Common system values, like time, are implemented. Hopefully you won't need platform specific values.

Get system variable and execute a Java Script

I'm not sure it is the appropriate forum to ask this
question. I'm using Captivate 2 without LMS.
I need to execute a java script that take read a system
variable (eg. USERNAME) and opens an URL using the USERNAMe as
parameter. The idea here is to update a database opening a specific
URL for a specific USERNAME.
Any one has an example to do something similar ?

Hello All,
Could anyone please help me with some examples or
tutorials how I can create Java Applet to run telnet
to UNIX and execute a shell script?
Presumably you don't need to write the telnet code yourself (like for a class.)
If so then you can use this...
http://jakarta.apache.org/commons/net/
There might be some other dependencies from other commons stuff that you will need to resolve to run it.
Once you have that, presumably you are not telnetting back to the source of the applet. If so you will need to deal with security for the applet. Usually that means that you must sign the applet. Otherwise you will have to modify the policy file on each client machine that will run the applet.

How do I get system variable of current process id?

For example:
select my_process_id from something.
to know what's the id of running job itself?

Use this:
select sid from v$session
where audsid=userenv 'sessionid');

System build-in or system variable to get number of records from a query

Hi,
Is there a system build-in or system variable to get number of records from a Oracle Forms query?
Thank you

Namely, when GO_BLOCK(BLOCK_NAME) EXECUTE QUERY finishes, is there a way directly get the number of the records?
SYSTEM.COURSOR_RECORD = 1 tells this is the first record
SYSTEM.LAST_RECORD = 'TRUE' tells this is the last record
Thanks

How to get system Environment variable?

How to get system Environment variable without using jni?
just like "JAVA_HOME" or "PATH"...
Any reply is help to me!! :-)

Thx for your reply...
I get it!!!
Read environment variables from an application
Start the JVM with the "-D" switch to pass properties to the application and read them with the System.getProperty() method. SET myvar=Hello world
SET myothervar=nothing
java -Dmyvar="%myvar%" -Dmyothervar="%myothervar%" myClass
then in myClass String myvar = System.getProperty("myvar");
String myothervar = System.getProperty("myothervar");
This is useful when using a JAVA program as a CGI.
(DOS bat file acting as a CGI) java -DREQUEST_METHOD="%REQUEST_METHOD%"
-DQUERY_STRING="%QUERY_STRING%"
javaCGI
If you don't know in advance, the name of the variable to be passed to the JVM, then there is no 100% Java way to retrieve them.
NOTE: JDK1.5 provides a way to achieve this, see this HowTo.
One approach (not the easiest one), is to use a JNI call to fetch the variables, see this HowTo.
A more low-tech way, is to launch the appropriate call to the operating system and capture the output. The following snippet puts all environment variables in a Properties class and display the value the TEMP variable. import java.io.*;
import java.util.*;
public class ReadEnv {
public static Properties getEnvVars() throws Throwable {
Process p = null;
Properties envVars = new Properties();
Runtime r = Runtime.getRuntime();
String OS = System.getProperty("os.name").toLowerCase();
// System.out.println(OS);
if (OS.indexOf("windows 9") > -1) {
p = r.exec( "command.com /c set" );
else if ( (OS.indexOf("nt") > -1)
|| (OS.indexOf("windows 2000") > -1 )
|| (OS.indexOf("windows xp") > -1) ) {
// thanks to JuanFran for the xp fix!
p = r.exec( "cmd.exe /c set" );
else {
// our last hope, we assume Unix (thanks to H. Ware for the fix)
p = r.exec( "env" );
BufferedReader br = new BufferedReader
( new InputStreamReader( p.getInputStream() ) );
String line;
while( (line = br.readLine()) != null ) {
int idx = line.indexOf( '=' );
String key = line.substring( 0, idx );
String value = line.substring( idx+1 );
envVars.setProperty( key, value );
// System.out.println( key + " = " + value );
return envVars;
public static void main(String args[]) {
try {
Properties p = ReadEnv.getEnvVars();
System.out.println("the current value of TEMP is : " +
p.getProperty("TEMP"));
catch (Throwable e) {
e.printStackTrace();
Thanks to W.Rijnders for the W2K fix.
An update from Van Ly :
I found that, on Windows 2003 server, the property value for "os.name" is actually "windows 2003." So either that has to be added to the bunch of tests or just relax the comparison strings a bit: else if ( (OS.indexOf("nt") > -1)
|| (OS.indexOf("windows 2000") > -1 )
|| (OS.indexOf("windows 2003") > -1 ) // works but is quite specific to 2003
|| (OS.indexOf("windows xp") > -1) ) {
else if ( (OS.indexOf("nt") > -1)
|| (OS.indexOf("windows 20") > -1 ) // probably is better since no other OS would return "windows" anyway
|| (OS.indexOf("windows xp") > -1) ) {
I started with "windows 200" but thought "what the hell" and made it "windows 20" to lengthen its longivity. You could push it further and use "windows 2," I suppose. The only thing to watch out for is to not overlap with "windows 9."
On Windows, pre-JDK 1.2 JVM has trouble reading the Output stream directly from the SET command, it never returns. Here 2 ways to bypass this behaviour.
First, instead of calling directly the SET command, we use a BAT file, after the SET command we print a known string. Then, in Java, when we read this known string, we exit from loop. [env.bat]
@set
@echo **end
[java]
if (OS.indexOf("windows") > -1) {
p = r.exec( "env.bat" );
while( (line = br.readLine()) != null ) {
if (line.indexOf("**end")>-1) break;
int idx = line.indexOf( '=' );
String key = line.substring( 0, idx );
String value = line.substring( idx+1 );
hash.put( key, value );
System.out.println( key + " = " + value );
The other solution is to send the result of the SET command to file and then read the file from Java. ...
if (OS.indexOf("windows 9") > -1) {
p = r.exec( "command.com /c set > envvar.txt" );
else if ( (OS.indexOf("nt") > -1)
|| (OS.indexOf("windows 2000") > -1
|| (OS.indexOf("windows xp") > -1) ) {
// thanks to JuanFran for the xp fix!
p = r.exec( "cmd.exe /c set > envvar.txt" );
// then read back the file
Properties p = new Properties();
p.load(new FileInputStream("envvar.txt"));
Thanks to JP Daviau
// UNIX
public Properties getEnvironment() throws java.io.IOException {
Properties env = new Properties();
env.load(Runtime.getRuntime().exec("env").getInputStream());
return env;
Properties env = getEnvironment();
String myEnvVar = env.get("MYENV_VAR");
To read only one variable : // NT version , adaptation for other OS is left as an exercise...
Process p = Runtime.getRuntime().exec("cmd.exe /c echo %MYVAR%");
BufferedReader br = new BufferedReader
( new InputStreamReader( p.getInputStream() ) );
String myvar = br.readLine();
System.out.println(myvar);
Java's System properties contains some useful informations about the environment, for example, the TEMP and PATH environment variables (on Windows). public class ShowSome {
public static void main(String args[]){
System.out.println("TEMP : " + System.getProperty("java.io.tmpdir"));
System.out.println("PATH : " + System.getProperty("java.library.path"));
System.out.println("CLASSPATH : " + System.getProperty("java.class.path"));
System.out.println("SYSTEM DIR : " +
System.getProperty("user.home")); // ex. c:\windows on Win9x system
System.out.println("CURRENT DIR: " + System.getProperty("user.dir"));
Here some tips from H. Ware about the PATH on different OS.
PATH is not quite the same as library path. In unixes, they are completely different---the libraries typically have their own directories. System.out.println("the current value of PATH is: {" +
p.getProperty("PATH")+"}");
System.out.println("LIBPATH: {" +
System.getProperty("java.library.path")+"}");
gives the current value of PATH is:
{/home/hware/bin:/usr/local/bin:/usr/xpg4/bin:/opt/SUNWspro/bin:/usr/ccs/bin:
/usr/ucb:/bin:/usr/bin:/home/hware/linux-bin:/usr/openwin/bin/:/usr/games/:

How to get the enclosing folder of an Application?

Ok. re-visiting my Applescript to compare installed apps versus a list of predefined apps... here is my test code so far:
set appsPath to (path to applications folder)
tell application "Finder"
set appList to name of every application file of entire contents of folder appsPath
end tell
set theApps to {"iMovie.app", "Microsoft Excel", "Microsoft Excel.app", "Adobe Acrobat 7.0 Professional.app", "Adobe After Effects CS4.app", "ColorEyes Display Pro.app", "Corel Painter X.app", "DiskTracker 2.3.2", "EPSON Scan.app", "Flash 8.app", "Product Ingest.app", "Product Tag.app", "Art Ingest.app", "TextWrangler.app", "Toast Titanium.app", "Suitcase Fusion 2.app", "Suitcase Fusion 3.app", "Fetch.app"}
repeat with anApp in theApps
set vers to version of (application anApp)
-- get parent path of anApp!!!!
if (parentFolder is equal to "Applications" or parentFolder is equal to "Utilities") then
set parentFolder to ""
end if
display alert anApp & ": Version: " & vers & " " & parentFolder
end repeat
The only thing I'm stuck on is how to get the parent folder of anApp. Basically we use several versions of software here that are not easily identifiable by the version attribute. However their enclosing folder has all the versioning info I need (e.g.: MS Excel 04's vers would be 110113, but the enclosing folder is "Microsoft Office 2004", and some departments get Office 2008, Office 2011, etc., so I need a human-friendly way to get the right versions)
I don't know if the "if" statement to check whether the parent is Applications or Utilities is correct as I haven't gotten that far in testing. I'm only interested in getting the parent of apps that have parent folder that is a sub-folder of Applications or Utilities.
Basically what I am trying to do here is write a text file containing all departmental apps, homefolder sizes, relevant partition sizes, etc. and spit it out at the tech responsible for migrating a user to a new mac (display alert is just convenient for testing purposes). In the past we've had too many "missed" items in QC like wrong apps installed, or wrong versions, or data not copied over properly, etc. So this way they can run this on the old system beforehand and the new system after, line everything up and check off if it matches. This is just a snippet...
TIA!

You must use the bundle identifier instead of the name

System variables in R/3 when badi is triggered from portal

Hi,
How can we know the action from the portal,i mean from the create expense report i want to throw an error message if the user press "Review" button based on my validation. i have written in the badi,but when the user press "Previous step" button also this badi is getting triggered and as per the validation it is throwing an error message, i cannot go back. Are there any system variables that we can capture which button he pressed from the portal so that i can control to throw an error message only when the user press "Review" button.

How can I get the variable with the value from Thread Run method?

We want to access a variable from the run method of a Thread externally in a class or in a method. Even though I make the variable as public /public static, I could get the value till the end of the run method only. After that scope of the variable gets lost resulting to null value in the called method/class..
How can I get the variable with the value?
This is sample code:
public class SampleSynchronisation
     public static void main(String df[])
sampleThread sathr= new sampleThread();
sathr.start();
System.out.println("This is the value from the run method "+sathr.x);
// I should get Inside the run method::: But I get only Inside
class sampleThread extends Thread
     public String x="Inside";
     public void run()
          x+="the run method";
NB: if i write the variable in to a file I am able to read it from external method. This I dont want to do

We want to access a variable from the run method of a
Thread externally in a class or in a method. I presume you mean a member variable of the thread class and not a local variable inside the run() method.
Even

could get the value till the end of the run method
only. After that scope of the variable gets lost
resulting to null value in the called method/class..
I find it easier to implement the Runnable interface rather than extending a thread. This allows your class to extend another class (ie if you extend thread you can't extend something else, but if you implement Runnable you have the ability to inherit from something). Here's how I would write it:
public class SampleSynchronisation
public static void main(String[] args)
    SampleSynchronisation app = new SampleSynchronisation();
public SampleSynchronisation()
    MyRunnable runner = new MyRunnable();
    new Thread(runner).start();
    // yield this thread so other thread gets a chance to start
    Thread.yield();
    System.out.println("runner's X = " + runner.getX());
class MyRunnable implements Runnable
    String X = null;
    // this method called from the controlling thread
    public synchronized String getX()
      return X;
    public void run()
      System.out.println("Inside MyRunnable");
      X = "MyRunnable's data";
} // end class MyRunnable
} // end class SampleSynchronisation>
public class SampleSynchronisation
public static void main(String df[])
sampleThread sathr= new sampleThread();
sathr.start();
System.out.println("This is the value from the run
method "+sathr.x);
// I should get Inside the run method::: But I get
only Inside
class sampleThread extends Thread
public String x="Inside";
public void run()
x+="the run method";
NB: if i write the variable in to a file I am able to
read it from external method. This I dont want to do

Your main thread continues to run after the sathr thread is completed, consequently the output is done before the sathr thread has modified the string. You need to make the main thread pause, this will allow sathr time to run to the point where it will modify the string and then you can print it out. Another way would be to lock the object using a synchronized block to stop the main thread accessing the string until the sathr has finished with it.

System variables not showing correctly in body pages

Can anyone help with a problem I'm having with system variables please?
I have created a template and multiple documents which all use a system variable for placing the chapter number and page number in the footer: <$chapnum>-<$curpagenum>
I have just created a new document and want to use the same variable on the main pages of the document but I want to use a different page number variable on the TOC. For some reason now, when I create a new variable of <$curpagenum> it doesn't show correctly on the document; it's showing as: <$curpagenum
I've also tried using the format of <$chapnum>-<$curpagenum> that has worked on other documents but now this shows in the document footer as: <$chapnum<$curpagenum
Has anyone seen this problem before?
Thanks

Hi Art, thanks for the reply.
In my original documents I'd edited the Current Page system variable from <$curpagenum> to <$chapnum>-<$curpagenum>. This worked correctly.
In the new document I tried both the picking-and-clicking method and typing the string to get the same footer but neither worked.
I've now changed it as you suggested, selecting the two seperate system variables of <$chapnum> and then <$curpagenum> and this seems to have solved the problem.
I'll know to keep things simple in future!
Thanks.

On. Startup I get a flashing folder icon with a question mark

My computer won,t start. After about 30 seconds I get a blinking folder icon with a question mark. I have never seen this before.

There are four general causes of this issue:
1. The computer's PRAM no longer contains a valid startup disk setting when there aren't any problems with the disk itself. This can be checked for by pressing the Option key and seeing if the drive appears.
2. The internal drive's directory structure has become damaged. This requires usage of an alternate bootable system to perform the repair.
3. Critical system files have been deleted. This requires usage of an alternate bootable system to reinstall them.
4. The internal drive has died or become unplugged. This is the most likely case if the computer took a sharp impact or there are unusual sounds coming from its location.

When I start my Mac air I get a flashing folder with a question mark

I am trying to start my Mac air and I get a flashing folder with a question mark. When I turn the power of it shuts down but wen starting it comes back

Just being clear about your situation. When you hold down Option during boot it does not show a system volume or a recovery volume from which to boot. At that point if you select a network boot and you do not see a spinning globe that persists there a good while as it loads the recovery partition over the network. True?
A couple of more thinks to try:
Disconnect all of your external devices.
Reset PRAM
Boot with the option key again.
Standard things to try (which is sounds like you already have attempted) A flashing question mark appears when you start your Mac
