Exit status running java classpath in a unix shell script

I'm new to putting java into unix scripts. I have a java classpath running inside of a unix shell script. During my testing it will error with java.io.FileNotFoundException error, which I know why that is, but when I set in my unix shell script this to see the right exit status of success/fail, it always shows a 0 for success when that isn't really the case. Below is the two lines I have set to capture the exit status and just display that exit status for now.
notifycode=$?
echo $notifycode
I have these 2 lines above on a line right below my java command in my unix shell script. How can I get my unix shell script to show the right exit status if the java classpath command fails? Thanks for any help.

That's Java code, it says "End this Java application and send return code 1 back to the shell". As for how the shell gets the return code from the application, that's a question about your shell and not about Java programming, no?

    Sounds like you either have a corrupt class file or you're using an older version of the JVM to try to execute classe that were compiled for a newer version.

  • Error while executing unix shell script from java program

    Hi All,
    I am trying to execute unix shell script from a java program using Runtime.execute() method by passing script name and additional arguments.
    Code snippet :
    Java Class :
    try{
         String fileName ="test.ksh";
         String argValue ="satish"; // value passed to the script
         String exeParam = "/usr/bin/ksh "+fileName+" "+argValue;
         Process proc = Runtime.getRuntime().exec(exeParam);
         int exitValue = proc.waitFor();
         sop("Exit Value  is : "+exitValue);

    when i am running the same command (/usr/bin/ksh test.ksh satish) manually, it's calling abc.exe file successfully
    and able generate the logs properly.
    Pls let us know where exactly i am stuck..
    Thanks in advance,

    Hi Sabre,
    As per the guidelines provided by the article, i had done below changes..
    InputStream is = null;
    InputStreamReader iStreamReader = null;
    BufferedReader bReader = null;
    String line = null;
    try{
    String fileName ="test.ksh";
    String argValue ="satish"; // value passed to the script
    String exeParam = "/usr/bin/ksh "+fileName+" "+argValue;
    Process proc = Runtime.getRuntime().exec(exeParam);
    is = proc.getErrorStream();
    iStreamReader = new InputStreamReader(is);
    bReader = new BufferedReader(iStreamReader);
    System.out.println("<ERROR>");
    while((line = bReader.readLine()) != null)
    System.out.println("Error is : "+line);

  • Java exec() of UNIX shell script

    I have a java application that uses:
    p = Runtime.getRuntime().exec( cmdLine);
    to execute a UNIX shell script, for example:
    #!/bin/ksh
    . /export/pc112477/freeware/work1/wsEnv
    export PATH=/opt/sfw/bin:/usr/ccs/bin:/usr/bin:/usr/ucb:$PATH
    cd /export/pc112477/freeware/work1/usr/src/pkgdefs/SFWnmap
    /usr/ccs/bin/make -e ROOT=$ROOT install
    RESULT=$?
    if [ $RESULT = 0 ]
    then
    echo "Package source"
    cd /export/pc112477/freeware/work1/usr/src/pkgdefs/SFWnmapS
    /usr/ccs/bin/make -e ROOT=$ROOT install
    RESULT=$?
    fi
    exit $RESULT
    Some times the running of the script locks up depending on how much work the script has to, eg. if the make calls pkgmk for a small package it runs okay but if its a large package it locks up in pkgmk.
    The script itself works okay if run directly
    Does anyone have any ideas on why this locks up and how I could stop it doing it.
    Thanks

    For anyone who stumbles across this and needs an answer:
    To empty the standard error and output, you need to use getErrorStream() and getInputStream() on the Process object created when you execed your command. Create new InputStreamReaders with the streams from the process, then wrap those with BufferedReaders and read each line with a while loop. This is the basic thing you need to do:
    try{
    Process proc = Runtime.getRuntime().exec(command);
    InputStreamReader isr = new InputStreamReader(proc.getErrorStream());
    BufferedReader errReader = new BufferedReader(isr);
    String line;
    while((line = errReader.readLine()) != null)
    <do something with each line of error>
    } //end try
    catch(<errors>) {
    <do something with errors>
    } //end catch
    What you really should do is put the stream handling in a separate class that extends Thread, create an instance for the error and output streams, and start each one. There is a class called StreamGobbler that does this sort of thing. Look at http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html to find out more about it and read a detailed explanation of different problems with exec().

  • Run Unix command / Run Unix shell script from Forms9i

    Hi,
    I have a requirement to run Unix command and Unix shell scripts from Forms9i.
    I know HOST command cannot be used directly. I also know we can create some JAVA stored procedure to perform the task, but I don't want to create any JAVA stored procedure as there are some security concerns.
    Please point me towards any other way to achieve the same.
    I would really appreciate your help.
    Thanks,
    Kumar

    There is no reason why HOST can't be used. This is what it is for. As for using Java, it is not a stored procedure that you would be using, it would be imported Java (imported into the form).
    The best way to use the HOST command is to call a script (.sh) rather than calling a Unix command directly. This is because HOST will not pick up environment variables set at the system level. So the script would first need to set the necessary environment variables then call the desired commands.

    Please don't overwhelm us with so many details!  
    Just off the top of my head ... as a general approach ... something like
    nohup proca
    nohup procb
    nohup procc
    while (some condition checking that all three procs are still running ... maybe a ps -ef |grep  )
    do
    sleep 2
    done
    procd
    But, we'd really need to know what it is you are really trying to accomplish, instead of your pre-conceived solution.

  • Running SQLPLUS from UNIX shell script

    I'm not sure if this is the right forum, but...
    How can I execute a sql file from inside the UNIX shell script, logging on to Oracle w/o supplying a UID/pwd? Normally, we log into UNIX using our own logon, then sudo as another user to login to Oracle. Now, I'm trying to create a UNIX shell script, where I'm already sudo'd as the UserID that logs into Oracle. I've tried the following, but can't get it to work. I'm a UNIX scripting noob. Any ideas?
    example:
    #! /usr/bin/ksh
    sqlplus / \@test.sql << EOF
    exit;
    EOF

    I'm a UNIX scripting noob.In which case I feel obligated to point you at William Robertson's excellent article Database Shellscripts Considered Harmful. Save yourself a world of pain.

    Hi Experts,
    I have oracle procedure where in I have to pass the value of procedure parameter through unix script.
    Follwoing is the sample procedure which i tried to exceute from the unix.
    Procedure:
    create or replace procedure OWNER.PRC_TESTING_OWNER(OWNER IN VARCHAR2) AS
    sql_stmt varchar2(1000) := NULL;
    v_count number := 0;
    v_owner varchar2(100) := owner;
    begin
    sql_stmt:='select count(1) from '||v_owner||'.EMP@infodb where rownum<=10';
    execute immediate sql_stmt into v_count;
    DBMS_OUTPUT.PUT_LINE(sql_stmt);
    DBMS_OUTPUT.PUT_LINE(v_count);

    echo start
    sqlplus -s scott@DEV/tiger <<EOF >>result_1.txt
    set serveroutput on;
    select '$parm' from dual;
    exec owner.PRC_TESTING_OWNER('$parm');
    EOFThe script is working fine that is i am able to pass to parameter value through unix shell script. :)
    But if I want to pass the value of the owner in cursor , I am unable to pass this value through unix.
    Following the procedure which i am trying to implement.
    create or replace procedure OWNER.PRC_TESTING_OWNER(OWNER IN VARCHAR2) IS

    used in cursor? :(
    Can anybody help me regarding the same?
    Thanks in Advance !! :D

    It's not the parameter in the cursor that is the problem, it's that you are trying to use static SQL for something that won't be known until run time (the owner of the table).
    You would need to use something like ...
    declare
       l_owner        varchar2(30) := 'SCOTT';
       l_ref_cursor   sys_refcursor;  
       type l_ename_tab is table of scott.emp.ename%type;
       l_ename_array  l_ename_tab;
    begin
       open l_ref_cursor for
          'select ename
          from ' || l_owner || '.emp';
       loop
          fetch l_ref_cursor bulk collect into l_ename_array limit 10;
          exit when l_ename_array.COUNT = 0;
          for x in 1 .. l_ename_array.count
          loop
             dbms_output.put_line(l_ename_array(x));
          end loop;
       end loop;
       close l_ref_cursor;
    end;
