Starting Java Program with a bash Shell script

Hi !
I know this is a Linux query but I am putting it on this site to get different answers.
I want to start my Java program with a shell script. Can anybody give me a proper script to start my Java program?
I am using RH Linux 7.3 and JDK 1.4.
Can I start the Java program without starting the terminal? Just like the Sun One Studio4 'runide.sh' script.
Please help.
Bye Niteen

assuming you have your PATH and CLASSPATH variables set correctly, your script should look like this:
#!/bin/bash
cd <project_dir>
java <class> &
example:
#!/bin/bash
cd ~/projects
java project1.main_package.MainClass &
of course you could add some more elaborated stuff like compiling files before running the program, etc.
if you dont like terminals, try running "nautilus" (it's like Windows Explorer). i never use nautilus (especially for running scripts), so i cant guarantee it will work, although i dont see why it shouldnt...

Problem with running Bash shell scripts

I am unable to run Bash shell scripts on the UNIX Terminal application.
This is the transcript from the Terminal application.
Zhi-Yang-Ongs-Computer:/Applications/MetaPost/metapost-1.102 zhiyangong$ ./test1.sh
dyld: Symbol not found: _BC
Referenced from: /usr/local/bin/bash
Expected in: /usr/lib/libSystem.B.dylib
Trace/BPT trap
Zhi-Yang-Ongs-Computer:/Applications/MetaPost/metapost-1.102 zhiyangong$
Is this a problem with the the default installation of the Bash shell? Can I install the Bash shell on my own? If so, how can I do that?
Also, how can I get the dynamic linker, dyld, to refer to the symbol "_BC"? What does this symbol "_BC" refer to?

This was in your posted output:
/usr/local/bin/bash
You are NOT running the default bash, you are trying to run a private copy.
The default Mac OS X bash is located at
/bin/bash
Try the following:
/bin/bash ./test1.sh
Does that work?
What is the first line of your script? Is it:
#!/bin/bash
Or maybe
#!/usr/bin/env bash
/usr/bin/env would find the first bash in PATH . I find this most useful for finding perl on different systems, but sh, ksh, bash, zsh, csh, tcsh are all generally found in /bin so I do not bother using /usr/bin/env
And if you have
#!/usr/local/bin/bash
Then the person that wrote test1.sh choose to use something besides the default bash
Or maybe this script was transferred from some system where you needed to put your own copy of bash in /usr/local/bin because the vendor does not distribute bash
Then again, you have not showed us what is inside your script, so it is possible something in the script called something else which invoked the /usr/local/bin/bash
If that is the case, then you might try:
/bin/bash -x ./test1.sh
which should show you the commands executed before it died.

Error in calling SQL plus program with parameter from Shell script

This is my Shell script. I am trying to call in the SQL plus program with the parameter and the shell script is registered as a concurrent program.
PARAMETERS=`echo $1 |tr -d '\"'`
DB_USER_ID=`echo $PARAMETERS|cut -d" " -f3|cut -d"=" -f2`
CONN_STRING=$DB_USER_ID
REQ_DATE=`echo $PARAMETERS|cut -d" " -f9|cut -d"=" -f2`
timestamp=`date +%m-%d-%y-%H:%M:%S-%Z`
timestam=`date +%y-%m-%d`
sqlplus -s $CONN_STRING @ar_statement.sql $REQ_DATE
chmod 755 statement.sh
. statement.sh
My Sql plus program is like this.
set pagesize 0
set heading off
set feedback off
spool $GEC_TOP/log/ge_ar_statement.sh
select output_file_name
from fnd_concurrent_requests
where trunc(actual_completion_date) = '&2';
spool off;
exit;
When i run the concurrent program, i am getting the following error:
ar_statement: line 14: REQ_DATE: command not found
Enter value for 2:
User requested Interrupt or EOF detected.
ar_statement.sh: line 1: Enter: command not found
ar_statement.sh: line 2: User: command not found
ar_statement
Program exited with status 127
I am not strong at Unix Porgamming and i would request someone who can
help me out as soon as possible.
I need this solution quickly and thank everyone in advance.
Thanks.

Can you put your coding between code statements, like shown in the FAQ. It will be easier to read.
Looking at your script, my first guess is that crontab will not find your sqlplus since your script does not have $HOME/bin in the $PATH. From what I understand, running .profile in your script will not work either because variables are exported to sub-shells, not to the shell above. You can call your script with a dot like . ./script which means that the script will run like it was typed at the command prompt. But it will be less confusing to define appropriate variables in the script. eg.
ORACLE_SID=my_instance_name
ORACLE_HOME=/my_path_to_oracle_home_directory
LD_LIBRARY_PATH=$ORACLE_HOME/lib
PATH=$ORACLE_HOME/bin:$PATH
I remember some slightly different way of coding to handle the sqlplus return codes.
For instance:
sqlplus -s /nolog > /dev/null <<-EOF
connect system/manager
@ssm.sql
whenever oserror exit failure
whenever sqlerror exit failure
EOF
sql_err=$?
if [ $sql_err -ne 0 ]; then
echo "FAILURE"
else
echo "SUCCESS"
fiThe - in -EOF supresses tab's
Using connect will prevent ps from showing your login credentials
In some versions of bash the ending EOF needs to be at the beginning of the line to work.

Btw, if you "source" a script running it like . .script, than an exit in that script will log you out.

Invoking a bash shell script from Java code

Hi All
I am trying to invoke a Bash shell script using java code. The arguments required are "source wmGenPatch <source dir> <destination dir> no_reverse.
in the code I have specified the arguments considering the cannonical paths of the files as the code may run on Unix or windows platform.
I am getting a error while invoking Runtime.getRuntime().exec(args). The error is as follows :
"The Error Occurred is: CreateProcess: source D:\Package4.0\workspace\DiffEngineScripts\v4a02\wmGenPatch D:\Package4.0\workspace\fromImageFilesDir\ D:\Package4.0\workspace\toImageFilesDir\ no_reverse error=2"
It seems that error=2 indicates that the 'file not found' exception. But i can see the directories referred to in the error at place in the workspace.
Kindly advice.
Thanks in advance.

Hi All
I am pretty new to invoking bash shell scripts from java and not sure if i am progressing in right direction.
The piece of code tried by me is as follows
try {
               currentDir = f.getCanonicalPath();
          } catch (IOException e) {
          if (currentDir.contains("/")) {
               separator = "/";
          } else {
               separator = "\\";
          String args[] = new String[7];
          args[0] = "/bin/sh";
          args[1] = "-c";
          args[2] = "source";
          args[3] = currentDir + separator + "DiffEngineScripts" + separator

          args[4] = sourceFileAdd;
          args[5] = destFileAdd;
          if (isReverseDeltaRequired) {
               args[6] = "reverse";
          } else {
               args[6] = "no_reverse";
          try {
               Process xyz = Runtime.getRuntime().exec(args);
               InputStream result = xyz.getInputStream();
               InputStreamReader isr = new InputStreamReader(result);
               BufferedReader br = new BufferedReader(isr);
               String line = null;
               while ( (line = br.readLine()) != null)
                    System.out.println(line);
               int exitVal = xyz.waitFor();
               System.out.println("Leaving Testrun.java");
          } catch (Throwable t) {
               t.printStackTrace();
and on running the same i am getting Java.io.IOException with the stack trace

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?

ASP code to start a Java program (with parameters)

Hi! All,
I am trying to write some ASP code which should start a java program. Does anybody know a simple way to do this? Am new to ASP
Thanks

It doesn't have anything to do with java.
Basically you need to make a system call which will start an external application. The external application can be anything including something like "java MyClass".
So either find an ASP forum/board/newsgroup to ask how to do a system call or read some docs on it.

Bash shell script to exception when database has been shutdown

Running java program with arguments in Unix

Hi
I am a new newbie to java so pardon if this is too simple for you .
This is my scenario. I have a java program which parses an xml and writes a .dat file. I execute this testparser.java in unix environment like this
java testparser xml1.xml
and it retuns me a .dat file
But my issue is I have to run my parser program for 40 xml files. The requirement is I have to create a script file and possibly with a for loop which will loop through 1-40 xml files and return me the .dat file.
I am really at a loss here. I am new both to Java and Unix
So pls help me out
Thanks in Advance
G

You could just do this in Java. Make it take all 40 xml files on the command line, and convert them all with one program invocation.
If you want to do it in shell script, you can do something like
for tmp in `ls -1 *.xml`; do
java testparser $tmp
donedepending on your shell, etc.

Invoking a Package.Procedure via bash shell script

Hello All,

        then
                logit "Error While Generating The SQLPLUS Output File, Please Check"
                exit 1
        else
                logit "SQLPLUS Output File Has Been Generated Successfully"

The [ command has too many arguments coming from the echo and grep. You might put just that test part of the script in it's own little script and test it, it seems to say that whether there is an ERROR in $RETVAL or not. You might need to man test and see if you need a -z argument or something.
