Run Shell Script from Oracle Forms 11g using Java Classes and Weblogic webserver



1. Create a Shell File

Login to Linux, create a shell file, change the permissions as below:

 # cd /cms
 # pwd
 /cms

 # cat > testshell.sh
  #!bin/sh 
  ls -l > KS`date +%d%m%Y%H%M%S`



 # chmod 755 testshell.sh

2. Create a java class file as below

Modify host, user, password and command1 variables as per your system.

Note: You must add com.jcraft.jsch_0.1.31.jar file in your java library.

public class RunShell {
       public static void shellName()
       {
              String host="192.168.1.223", user="root", password="ks@123", command1="/cms/testshell.sh";
              try{           
            java.util.Properties config = newjava.util.Properties();
            config.put("StrictHostKeyChecking", "no");
           
            com.jcraft.jsch.JSch jsch = newcom.jcraft.jsch.JSch();
            com.jcraft.jsch.Session session=jsch.getSession(user, host, 22);
            session.setPassword(password);
            session.setConfig(config);
            session.connect();
            System.out.println("Connected");
            
            com.jcraft.jsch.Channel channel=session.openChannel("exec");
            ((com.jcraft.jsch.ChannelExec)channel).setCommand(command1);
            channel.setInputStream(null);
            ((com.jcraft.jsch.ChannelExec)channel).setErrStream(System.err);
            
            java.io.InputStream in=channel.getInputStream();
            channel.connect();
            byte[] tmp=new byte[1024];
            while(true){
              while(in.available()>0){
                int i=in.read(tmp, 0, 1024);
                if(i<0)break;
                System.out.print(new String(tmp, 0, i));
              }
              if(channel.isClosed()){
                System.out.println("exit-status: "+channel.getExitStatus());
                break;
              }
              try{Thread.sleep(1000);}catch(Exception ee){}
            }
            channel.disconnect();
            session.disconnect();
            System.out.println("DONE");
        }catch(Exception e){
            e.printStackTrace();
        }
       }
}

3. Compile the java file and create its jar file.

4. Copy RunShell.jar, com.jcraft.jsch_0.1.31.jarfiles in C:\Oracle\Middleware\Oracle_FRHome1\forms\java folder

5. Sign the jar file with sign_webutil utility available in C:\Oracle\Middleware\asinst_1\binfolder

6. Edit default.env file available in C:\Oracle\Middleware\user_projects\domains\ClassicDomain\config\fmwconfig\servers\AdminServer\applications\formsapp_11.1.2\config folder and add CLASSPATH variable with C:\Oracle\Middleware\Oracle_FRHome1\forms\java\com.jcraft.jsch_0.1.31.jar;C:\Oracle\Middleware\Oracle_FRHome1\forms\java\RunShellFile.jar;

7. Open Forms Builder

Create canvas, block, push button.

Go to Program Menu -> Import Java Classes… -> Select RunShell class -> Click Import Button.

Now you will file RunShell Package is created in Program Units.

Now write the code in WHEN-BUTTON-PRESSED trigger of push button as :
RunShell.shellName;

Where shellName is the function/method created in RunShell java file and is imported in RunShell Package in Program Units.
