Running Fop from JAVA program

Hi all,
this may be a rookie question....hope you can help.
I can run Fop (0.18.0) perfectly from the command line. I created a style
sheet (xsl file), which converts the xml file. On the command line, I input
the xsl file, the xml file, and state the name for the pdf file.
Now I'm trying to run Fop from within method in my JAVA program. This
doesn't seem to work. Here's the code. Can someone tell me what I'm doing
wrong? Is it okay to run Fop this way? My classpath is set up properly
(it runs on the command line).
Here's the code..............Thanks in advance for any help.
String [] pdfParams = new String[6];
pdfParams[0] = "-xsl";
pdfParams[1] = xslFile;
pdfParams[2] = "-xml";
pdfParams[3] = xmlFile;
pdfParams[4] = "-pdf";
pdfParams[5] = pdfFile;
org.apache.fop.apps.Fop.main(pdfParams);
Regards,
Suryakant.

When you post code, please use[code] and [/code] tags as described in Formatting tips on the message entry page. It makes it much easier to read.
One thing that jumps out at me is that you're calling waitFor() and then trying to read the process' stdout. But waitFor waits for the process to die, so the stream is no longer there when you try to read it.

Yes sombody knows. Yes it's possible. Have a look at Runtime#exec.

Creating and running JARs from Java programs

OK, I have been googling and searching, but this is something I cannot work out, so I raelly need some help.
Basically, I am building a GUI app that would generate, compile and run java programs. And I also want to enable the users to create JARs they can later double-click if they want to run the program.
I am using Runtime to compile programs and it works just fine. When I click on a button to create a JAR, my application creates one, but when I double-click on it, it can't find main and it exits. Now that is not so much unusual, but I am positive that my manifest file is OK, because when I run the same command from the command line, then I can click on the JAR file to run it.
So what is the deal here? I mean, why would a JAR file created from the command line run and the one created through a GUI app using the very same command could not find main?
Any help would be graetly appreciated.

again, another unanswered question.
BTW I'l keep bumping these until I get an answer that works. I have been up 3 hours now trying to get this sorted and it's something that netbeans is supposed to do on its own!?!?!?!?!
Hello, SUN, is there anyone there???
No, didn't think so.

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()));

                     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,

How to run Perl from Java

Hi,
I have a program written in Perl. I want to run the Perl program using Java. If there is a command which can allow me to call the perl program from Java program, please advise me.

The most easy way is to use Runtime class to call "perl" to run your perl script.
String sCmd = "c:\\yourPerlScriptLoc\\yourPerlScript.pl";
Process p = Runtime.getRuntime().exec(sCmd);

How to call 'WordPad' from java program........

The following code will open 'Notepad'
Runtime runt = Runtime.getRuntime();
Process pr = runt.exec( "notepad" );likewise, I want to open 'Wordpad'
Runtime runt = Runtime.getRuntime();
Process pr = runt.exec( "wordpad" );The above two line code, compiles successfully, but it doesn't give the correct result.
If I give 'wordpad' in start->run->'wordpad', in windowXP means, the Runtime executer opens 'WordPad',
can anyone give the solution to open WordPad from Java Programming.
thanks

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.

Calling oracle SQL Loader from java program

Hi,
I want to insert data into oracle tables from a text files containing fixed length fields. I am using SQLLoader to achieve this. The requirement is to call the SQLLoader within the java program.
Does anyone know how to call SQL Loader from java program?
Thanks,

Simply "exec" the sqlldr program with the parameters you need to pass to it.
Runtime.exec (........)
Try to pass all parameters needed including the username and password, and use the option "silent" to avoid output, and the option "log" to have a log file of the modifications that sqlldr has done to the database.

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.

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.
