Psql syntax run within java code - Mailing list pgsql-novice

Hi,

I have a problem with running a psql command from within my java application. I am pretty sure it is a syntax problem,
butthe same command run at the sql interface works. 

Here is my syntax:

                  strQueryForExportDump = "psql -d car -c 'select id from pegs1' ";
                        objProcess=objCurrentRuntime.exec(strCommand);
                        BufferedInputStream in = new BufferedInputStream(objProcess.getInputStream());
                        byte [] b = new byte[80];
                        in.read(b,0,30);
                        String cmdOut = new String(b);
                System.out.println("cmd out1 is " + cmdOut);

                        byte []er = new byte[580];
                        BufferedInputStream err = new BufferedInputStream(objProcess.getErrorStream());
                        err.read(er,0,580);
                        String cmdErr = new String(er);
                System.out.println("err stream is " + cmdErr);

This is the output I see from the log:

dump str is psql -d car -c 'select id from pegs1;'
cmd out1 is
err stream is psql: warning: extra command-line argument "from" ignored
psql: warning: extra command-line argument "pegs1;'" ignored
psql: FATAL:  user "id" does not exist

Please help.
