Run dial-up connection from Java Program?

Is there a way to run dial-up connection from a Java Program? It needs to platform independent.
Thanks.
Virum

I very much doubt it, at least not platform independent. I had a, oops, heck of a time doing that from Visual Basic, where it is much easier to work with operating-system stuff like that than it is in Java. I finally ended up buying a RAS component to call from my VB program.

Accessing Windows dial-up connections from java

Hello,
Anyone has any idea how to go about accessing Windows existing dialup connections and instruct windows to dial-up to internet using the selected connection profile?

1. why are you using java for a Windows only program?
2. why are you attempting to do something windows specific for
a non-os specific language
WOW!
I've been using java for applications I only run on Windows, Didn't know this is frowned own. You gotta be kidding me right? Do you really think all java programs are written in mind for it be be platform independant? I've been programming in java for around 3 years and we only run it on Windows systems. Non-os specific is nice, but everyone that programs using java isn't looking for that feature. If everyone else out there is only using java because it's platform independance please correct me, I'll be very surprised. One more question, just becaus he is possibly only going to use for a windows program, he should go learn another language? Sorry this post really surprised me.

URGENT:- Running a batch file from java program

Author: pkanury
I am trying to execute a batch file from my java program using RunTime and Process . It can execute any dos command except for a batch file. Can anyone throw
some light ?? My code looks like this .....
cmd = "command.com /c X:\\grits\\scripts\\test.bat"; Runtime rt = Runtime.getRuntime(); Process p = rt.exec(cmd);
The weird part is that p.waitFor() returns a status of 0 implying that the cmd has been executed successfully. But that is not the case. And my batch file is as simple as - type "ADADA" > junk.txt
Any help would be appreciated.

I think it should work when you use a String[] array
instead of a single String:
String[] cmd = { "command.com", "/C", "D:\\batch\\do.bat" };
Note: If the batchfile creates any output (i.e. files),
they will be stored in the directory of the application
which calls the batch file, not in d:\batch\...

Problems in SQL Connection from Java program to Oracle 8.1.7

Hi,
I am java program that connects to Oracle 8.1.7 .
Client: java code on Windows 2000
Server: oracle 8.1.7 on Solaris
Java code uses two types of Connection Pools. One Pool uses "thin" connections and other pool uses "OracleConnectionPoolDataSource" class.
The methods which use "thin" pool work great however the methods which use "OracleConnectionPoolDataSource" fail after 5 to 10 calls.
Given below is the exception that I see in my log file.

Problem while running dos command from java program

Dear friends,
I need to terminate a running jar file from my java program which is running in the windows os.
For that i have an dos command to find process id of java program and kill by using tskill command.
Command to find process id is,
wmic /output:ProcessList.txt process where "name='java.exe'" get commandline,processid
This command gives the ProcessList.txt file and it contains the processid. I have to read this file to find the processid.
when i execute this command in dos prompt, it gives the processid in the ProcessList.txt file. But when i execute the same command in java program it keeps running mode only.
Code to run this command is,
public class KillProcess {
     public static void main(String args[]) {
          KillProcess kProcess = new KillProcess();
          kProcess.getRunningProcess();
          kProcess = new KillProcess();
          kProcess.readProcessFile();
     public void getRunningProcess() {
          String cmd = "wmic /output:ProcessList.txt process where \"name='java.exe'\" get commandline,processid";
          try {
               Runtime run = Runtime.getRuntime();
               Process process = run.exec(cmd);
               int i = process.waitFor();
               String s = null;
               if(i==0) {
                    BufferedReader stdInput = new BufferedReader(new
                           InputStreamReader(process.getInputStream()));
                    while ((s = stdInput.readLine()) != null) {
                     System.out.println("--> "+s);
               } else {
                    BufferedReader stdError = new BufferedReader(new
                           InputStreamReader(process.getErrorStream()));
                    while ((s = stdError.readLine()) != null) {
                     System.out.println("====> "+ s);
               System.out.println("Running process End....");
          } catch(Exception e) {
               e.printStackTrace();
     public String readProcessFile() {
          System.out.println("Read Process File...");
          File file = null;
          FileInputStream fis = null;
          BufferedReader br = null;
          String pixieLoc = "";
          try {
               file = new File("ProcessList.txt");
               if (file.exists() && file.length() > 0) {
                    fis = new FileInputStream(file);
                    br = new BufferedReader(new InputStreamReader(fis, "UTF-16"));
                    String line;
                    while((line = br.readLine()) != null) {
                         System.out.println(line);
               } else {
                    System.out.println("No such file");
          } catch (Exception e) {
               e.printStackTrace();
          return pixieLoc;
}     when i remove the process.waitFor(), then while reading the ProcessList.txt file, it says "No such file".
if i give process.waitFor(), then it's in running mode and program is not completed.
Colud anyone please tell me how to handle this situation?
or Is there anyother way to kill the one running process in windows from java program?
Thanks in advance,

Calling a function in an EXE file from Java Program

Hi Im having a function which is written in c program.i need to call that function from my java program, if i create a shared library (DLL) for my C code then it works but my requirement is i dont want to create that DLL , like in it would be an executable and my java code should access that function in that C program

I understand the usage od a DLL but the thing is if i convert the exe to a DLL
the server doesnt start at all so what i need is that i dont want to change
that .EXE into a .DLL,let it be an executable. that executable is in running mode
and through my java program i need to call a function in that EXE file.
Is ther any way to do it?Nope, but you have another problem: why can't you separate your server program
into a .dll part and a startup part? Both, when properly linked against each other
should give you an executable file.
kind regards,
Jos

SOLVED: How To Use LDAP over SSL (no certs) from java program

Trying to connect to OID from Java program (using Grocery Store demo as a test). Want to use SSL with no server certificate. OID is configured, and ldapsearch -U 1 works.
Tried using URL with ldaps, or adding SECURITY_PROTOCOL,"ssl". In both case the error is 'simple bind failed'.
Samples on OTN say this should be possible, but then only have code for the non-ssl connection.
Posting from others with this same question don't seem to have been answered.
Message was edited by:
user590350
I have found that using ConnectionUtil.getSSLDirCtx() from Oracle will make a no-authentication SSL connection. An example in the sample code would be useful.

Even with Java APIs, There is a way to talk through SSL without bothering about certificates. It's just that you will have to write some code and make some changes in settings.
Read following to get further information on the same.

I don't know or I won't comment whether it's the right approach or not but it's definitely a work around.

MySQL trying to connect my java program

I have typed out this example that is in a text book I have and I am trying to connect my java program to a MySQL database. The version of MySQL is 4.1 which I have recently downloaded onto my computer and is working fine. The problem I am having is in ther places where it says "WHAT DO I ENTER HERE", basically the 'database.properties' , the 'jdbc.drivers' and the 'jdbc.url' string names. I do not know what I am supposed to enter. If you could give me some help with what I am supposed to enter or an example of a java program that already works with MySQL that would be of great help to me. A working example would be the greatest help to me .

Setting windows environment variables from Java program

Is there any way to set environment variables from Java program in Windows? Any help is appreciated.
Here is my situation:
I need to decrypt an encrypted Oracle user password in a batch file which will be used while running a sql script with sqlplus. I was planning to have bat file which will call a Java program decrypt the password and set it as an env variable in windows which will be available while calling sqlplus.
thanks

Runtime.exec has a lot of overloadings. Two of them
allows you to specify the environment variables.
exec
public Process exec(String[] cmdarray,
String[] envp,
File dir)
throws IOExceptionExecutes the specified command and
arguments in a separate process with the specified
environment and working directory.
cmdarray - array containing the command to call and
its arguments.
envp - array of strings, each element of which has
environment variable settings in format name=value.
dir - the working directory of the subprocess, or null
if the subprocess should inherit the working directory
of the current process.
I had this sample program:
public class SetVarExample {
public static void main (String[] args) throws Exception {
     String[] cmd_env= new String[] {"password="+"ABCD","Path=C:\\Sun\\AppServer\\jdk\\bin"};
     String cmd = "cmd /c SET ";
     Runtime.getRuntime().exec(cmd,cmd_env);
System.out.println( "Finish ...." );
I tried it in a command prompt. But looks like when the program exits, it's a whole new process and so it does not retain the env variables set in the java program.
Any suggestions? Am I doing it worng?
thanks

Once you mounted the CDROM (something maybe as /media/cdrom) as a file system (or assigned a drive letter to it like D: or F: or whatever), the files are accessible normally.
