Finding the current path

Hey all,
what is the shortest way to get the current directory?

You can also call System.getProperty("user.dir"), which will return the user's current working directory as a String. Using "user.home" as the method parameter will give you the user's home directory. So if you want/need either of those directories, there's a simple 1-line way to obtain the values.

Find the installation Path of the current running VM on Windows

Hello,
I have a java class started by webstart.
In this class I would like to find the absolute path of the current running vm? This is important to me because I need to start an exe file (using ProcessBuilder) and hand it the path of the java VM,
For example I could try something like this:
private static File findJDK() throws Exception {
String s = System.getProperty("java.home");
File myJRE = new File(s);
if (new File(myJRE, "bin/javac.exe").isFile()) {
return myJRE;
File parent = myJRE.getParentFile();
if (new File(parent, "bin/javac.exe").isFile()) {
return parent;
for (String pathel : System.getenv("PATH").split(File.pathSeparator)) {
File bindir = new File(pathel);
if (new File(bindir, "javac.exe").isFile()) {
return bindir.getParentFile();
return myJRE;
But I would like the above code to be more fool proof!
For example the "java.home" could be wrongly set.
Since java is allready running I would have hopped that I could query the Runtime. But there seems to be no method providing the running java VM path?
I also tried looking at the jnlp services API but no luck.
I would be also interested find the lastest java VM on the client Windows machine....
Many greetings

How to get the current path of my application in java ?

how to get the current path of my application in java ?
thanks

To get the path where your application has been installed you have to do the following:
have a class called "what_ever" in the folder.
then you do a litte:
String path=
what_ever.class.getRessource("what_ever.class").toString()
That get you a string like:
file:/C:/Program Files/Cool_program/what_ever.class
Then you process the result a little to remove anything you don't want:
path=path.substring(path.indexOf('/')+1),path.lastIndexOf('/'))
//Might be a little error here but you should find out //quickly if it's the case
And here you go, you have a nice
C:/Program Files/Cool_program
which is the path to your application.
Hooray

How to get the current path/directory

Hey,
I was wondering how to figure out the current path or directory where my Application is running (stored) in! I know there is a statement like getCodebase() for Applets to get the actual path, but I couldn't find anything similar for regular Applications. I think I can not just use a absolute path, since it might run on different os with different file seperator (like /root or c:\). Any help is welcome!
Thank you very much,
Marc

Try this ...
System.out.println("current directory = " + System.getProperty("user.dir"));

How to find the menu path ?

Hi all,
I have one doubt how do we find out the correct menupath if we know the t-code ?
for example, SE11 -DDIC
we can also obtain the same DDIC screen via menupath from SAP main screen.
if I know only t-code.how can i find out the menupath ?
thnks and rgds,

Hi Raghul,
You can go to the transaction search_sap_menu
for finding the menu path.
check this link:

Issue in finding the current row

I am rendering rows of a VO using an iterator component. One of the component I am rendering is a declarative component created by me.
In this component there is a clickable link on which i can write any method to achieve desired functionality.
Since, iterator is used so the current row is set to the last row. Now on clicking the link in the declarative component i need to do some operation based on the current row (pk of that row). So, how to find the current row id?
Note: If it would be a simple adf component like a commandLink i could have inserted a setServerListener inside it and could have put the id in to requestScope to access it. But as this is the declarative component in which i cannot create a serverListener so I am looking for some other solution.

Hi john,
My table have the selection listener.
Thanks in advance

Finding the exact path of a file using a Java program

Can anyone tell me how to find the exact path of a file which is saved in a directory other than the one in which the main file is saved? I know there is a class called File which has many methods like isAbsolutePath() and isPath() but they return the path in which the main class is located

actually i m trying to write a program which will
take a name of a file or a directory from the console
and it should give the entire path of that file or
directory and this file need not be stored in the
path of the main class.....It can be stored in any
drives of my PC....Ok, then the console input needs to be an absolute path or a path relative to some given directory (usually the one from which the application is started). Java cannot magically guess absolute paths if you just provide a file name. E.g. if I'd use your program and would provide as input "build.xml", how should the program know which file by that name I mean (there are lots of build.xml files in different locations on my machine)?

Finding the context path or docBase in a backing bean - Howto

How should I go about finding the context path or docBase in a backing bean?
Is there anyway to get this from glassfish or jsf? GlassFish proudly displayed it on the Application Server > Applications > Web Applications > page. It puts it there with an EL for example:
${com.sun.aas.instanceRoot}/applications/j2ee-modules/jsf-witaCan and/or should I try to use it in a backing bean? i.e. can I rely on it to stay defined?
Or should I make a property which I can set for my backing work?

Is this what you want?
FacesContext.getCurrentInstance().getExternalContext().getContext()

Finding the shortest path

Hey guys,
Im working on a solution to this problem below is a program to allow a user to draw straight line paths. What i'd like to do is allow the user to select two points on the path he has drawn and find the shortest path among all the interesecting lines.....im going crazy thinking of a solution for this.....im thinking bout steeping down a notch and just try to find just any path first.
Will really appreciate any help.

How to Find the Current Instance Id in Oracle 10g

Hi,
how to find the current instance id in oracle 10g studio,
I have the below code :
if (InstanceScreenFlow.processInstance.id.id.indexOf(text : ins.id) < 0) {
/// do something
it is saying that "'processInstance' is not a function"
Thanks,
Brijesh Kumar Singh.

Why not just pass in the "id" predefined variable into your screenflow? Once you do that you'll be able to refer to it as "id.id" anywhere inside your screenflow.

How to find the current SQL

Dear All,
My testing engineers are checking the application from front end, i have to find the current SQL (What SQL queries are used in the application) statements in the back end.
Please let me know how to find the current executing SQL stements.
Thanks in advance
Mahi

You need to join this query with one more table - v$sqlstats. There are many statistics in particular cpu_time, elapsed_time etc stored in that table for each sql statement.
You can join v$sqlstats by sql_id until you have multiple child cursors for single statement.
Or you can just join to v$sql and get statistics from there and in this latter case you include child_number column to distinguish child cursors from each other.

Can I find the current tab in Terminal using applescript?

Running a script from the shell by prepending
#! /usr/bin/osascript
as part of my .profile, can I find the "current" tab using Applescript. Most of the time, the "current" tab will not be visible, as the shell is being initialised, or re-initialised.
I want to set the dircolors for my shell by determining the background color of the tab in which the shell is executing.

Under the Window menu you can activate any of the palettes that you want. In your case the Field tab is under the Object palette
