Hi,
I want to find the installed JREs in windows using java. I couldn't fine any java API. So I am using the below code to fetch the JRE list from windows registries & parse the returned collection to know the installed JRE.Why? If you are running java you already have a JRE. So why not just use it?
>
String key = "HKEY_LOCAL_MACHINE\\SOFTWARE\\JavaSoft\\Java Runtime Environment";
Runtime.getRuntime().exec(
"reg query " + "\"" + key + "\"");
Is it legal to retrieve the installed JREs in this way? Legal? It is OS specific, and to a certain extent dependent on vendor and what the vendor wants to do. Could also be impacted by permissions. Other than that it is ok.
I am feeling like its a type of hacking. So I couldn't decide whether this is legal (recommended) way of using. Does anybody can answer me. I can see the similar posts in google. Somebody suggests this way & somebody suggests to use preference API which is similar to this. Appreciate your help.Preferences won't work. It doesn't allow access to the registry in general, only a part of it. There are discussions in the JNI forum about retrieving VM versions. Prior to actually using the VM though.

How to Create Linux-Cron Job from a Java Program

Hello,
Can anybody help me to CREATE/EDIT/DELETE Linux Cron job from Java Program. Its Very Urgent.Thanks in advance..
from
Chakri

I decided this didn't sound too tough so I played around with it a little. Basically because I'd never tried executing external processes out of java before, so I wanted to see how it was done.
Just change whatever you like in the jobs ArrayList and call writeJobs.
If you call writeJobs without putting anything in the list first you'll wipe out all of your crontab entries.
import java.lang.*;
import java.io.*;
import java.util.*;
public class cron {
    ArrayList jobs;
    Runtime rt;
    cron() {
     rt = Runtime.getRuntime();
     jobs = new ArrayList();
    void readCron() {
     String[] list = { "crontab", "-l" };
     jobs = new ArrayList();
     try {
         // Stick a job into crontab
         Process child = rt.exec(list);
         BufferedReader cronout = new BufferedReader(new InputStreamReader(child.getInputStream()));
         String cronjob = cronout.readLine();
         while (cronjob != null) {
          jobs.add(cronjob);
          cronjob = cronout.readLine();
         child.waitFor();
     catch(IOException e) {
         System.err.println("IOException starting process!");
     catch(InterruptedException e) {
         System.err.println("Interrupted waiting for process!");
    void listJobs() {
     Iterator iter = jobs.iterator();
     while (iter.hasNext()) {
         System.out.println((String)iter.next());
    void writeJobs() {
     String[] edit = { "crontab"};
     try {
         // Stick a job into crontab
         Process child = rt.exec(edit);
         PrintWriter cronIn = new PrintWriter(child.getOutputStream());
         Iterator iter = jobs.iterator();
         while (iter.hasNext()) {
          cronIn.println((String)iter.next());
         cronIn.close();
         child.waitFor();
     catch(IOException e) {
         System.err.println("IOException starting process!");
     catch(InterruptedException e) {
         System.err.println("Interrupted waiting for process!");
    void doStuff() {
     readCron();
     listJobs();
     jobs.add("* * * * 4 cronjob");
     writeJobs();
     readCron();
     listJobs();
    public static void main(String[] args) {

How do you query Oracle RDF database using Java program?

Does anyone know how to get data out of the oracle RDF database using Java?
I'm running the following java code and it returns basically null values. My guess is that the get_triple() function returns a dataset other than resultset. I've tried searching the Oracle web site. Am I supposed to be using CLOB object? Any help would be appreciated. Thanks
sql = "SELECT a.triple.GET_TRIPLE() AS triple FROM family_rdf_data a";
ResultSet rs = stmt.executeQuery( sql ) ;
while ( rs.next() )
System.out.println( rs.getString(1) ) ;
rs.close() ;

get_triple() returns an object, and the code would be different from the code of retrieving a string. Some sample code for retrieving objects is at http://www.oracle.com/technology/sample_code/tech/java/sqlj_jdbc/files/advanced/advanced.html
get_subject(), get_property() return strings so the code below should work. get_object() returns a CLOB so different handling would be required and there is some sample code at the link above.

How to create a subreport link programmaticly using java RAS sdk

Hi,
I want to create subreport link for couple of main report parameters programmaticly using RAS sdk.
Main report has Param1 and Param2. I need to link these parameters to sub-report which doesn't have any parameters, so I can pass the parameters value just once when running the report and consume it's value in the sub-report.
Below is the code I tried but I get "Invalid field name"error when I try to save the main report.
ISubreportClientDocument subReportDoc = subReportCntrl
.getSubreport(subReports.getString(i));
SubreportLinks srLinks = subReportCntrl.getSubreportLinks(subReports.getString(i));
SubreportLink subRptLink1 = new SubreportLink();
Fields paramFields = reportClientDoc.getDataDefinition().getParameterFields();
subRptLink1.setMainReportFieldName(paramFields.get(0).toString());
subRptLink1.setSubreportFieldName(paramFields.get(0).toString());
SubreportLink subRptLink2 = new SubreportLink();
subRptLink2.setMainReportFieldName(paramFields.get(1).toString());
subRptLink2.setSubreportFieldName(paramFields.get(1).toString());
srLinks.add(subRptLink1);
srLinks.add(subRptLink2);
subReportCntrl.setSubreportLinks(subReports.getString(i), srLinks);
Thanks,

How to create a semi circuler slider using java swing or awt

I am trying to create a Jslider like thing but in semicirculer shape. Thanks in advance for providing any help.

Is it possible to create such UI in java swing?Just to further illustrate, Swing only provides the raw foundation you need to be able to build a GUI. With the stock components you can create static user interfaces with standard controls. If you want to go further, you need to either find a component that somebody else already wrote, or you go into custom painting as previous posters suggested. To do an animating component for example, you would need all the frames as BufferedImage objects and you would combine custom painting with a Swing timer to update the displayed frame at a specified framerate.
if you search for "java swing animation" using google, I'm sure you can find the examples you need. And here is the trail about swing timers:

Hi All,
I have a doubt. I want to create a folder using java.
Inputs are the destination where the folder should be created and the name of the folder. Plz help me in this regard.
thanks and regards,

check out javadoc for java.io
File reldir=new File("NewDir");//relatively where your program runs
reldir.mkdir();
File absdir=new File("C:/NewDir");//absolute path
reldir.mkdir();
File newdir=new File(absdir,"SubDir");//defines another dir under absdir
newdir.mkdir();

How to create /home directory in a diferent disk ?
Edited by: user1502 on Apr 25, 2012 1:51 PM

I'm confused. It looks like you already have /home configured:
<pre># zpool status
pool: home
state: ONLINE
scan: none requested
config:
NAME STATE READ WRITE CKSUM
home ONLINE 0 0 0
c4t3d0 ONLINE 0 0 0
errors: No known data errors
# zfs list
NAME USED AVAIL REFER MOUNTPOINT
home 86K 134G 32K /home
...</pre>
What is the problem? Looks like you already have /home configured. Are you sure automounter is not running?
Try this:
<pre>zfs set mountpoint=none home
rm -rf /home
zfs set mountpoint=/home home</pre>
