I have a java program which is supposed to launch a shell script. The script contains 6 tasks which are to be executed in sequence. The java program launches the script and it starts(as I see the logs). But after 10-15 seconds, the execution stops, even before the first task in the shell script is completed. The strange thing is that the script runs fine when I launch it in terminal. To avoid risking the program to hang while the script is being executed, I launch it in a separate thread. What might be a probable reason?

Java code –

try {   
            log.info("run cmd - "+optionsRun);

            String[] cmdLine = (String[]) optionsRun.toArray(new     String[optionsRun.size()]);

            Process process = Runtime.getRuntime().exec(cmdLine);
            log.info("end run cmd " + this.getScriptPath());

//          
//          BufferedWriter writer = new BufferedWriter(new     OutputStreamWriter(process.getOutputStream()));
//          writer.write("mypwd");
//          writer.flush();
//          writer.close();


            InputStream is = process.getErrorStream();
            String error = inputStreamToStringValue(is);
            log.trace("Eventual error was : " + error);

            InputStream os = process.getInputStream();
        String output = inputStreamToStringValue(os);
            log.info("Eventual output was : " + output);

            if (error!=null & error.length()>0) {
                throw new ActionProcessingException("An error occurred when     running the script :'"+this.getScriptPath()+"' with following error message : "+error);    
            }else {
                log.info("Script run ended successfully.");
            }

And the shell script looks this way –

#!/bin/sh
# ./publish <path-to-publish-home-folder> <workspace_id> <start_date> <end_date>
# ./publish <path-to-publish-home-folder> 100011 2010-01-06-12:00:00-CET     2012-01-14-19:00:00-CET

rm -f $1/publish.log
echo 'Start publish' >> $1/publish.log
echo $0 $1 $2 $3 $4 $5 $6 $7 $8 $9 >> $1/publish.log

# lancement de l'export RDF du domaine
cd $1/1-export-domain
echo "Starting export domain with the command - ./export.sh $2" >> $1/publish.log
./export.sh $2

# lancement de l'export des translations du domaine
cd $1/2-export-trans
echo "Starting export domain(translated) with the command - ./export.sh $2" >>         $1/publish.log
./export.sh $2
.....
.....
a couple of more steps like 1 and 2

Thanks in advance,
