Short Description

I have to run Ghostscript on AIX. It works in command line:

XXXXXXXX:i2zate:/home/i2zate>/usr/bin/gs -dFIXEDMEDIA -dPDFFitPage -dFirstPage=1 -dLastPage=1 -dBATCH -dNOPAUSE -dNOPROMPT -dSAFER -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=0 -dDEVICEWIDTH=90 -dDEVICEHEIGHT=120 -dORIENT1=true -sDEVICE=jpeg  -dTextAlphaBits=4 -dGraphicsAlphaBits=4 -sOutputFile=1.jpg porsche.pdf

If I run the same from Java, it displays an error:

ERROR: exec(): 0509-036 Cannot load program /usr/bin/gs because of the following errors:
ERROR:  0509-022 Cannot load module /usr/lib/libcairo.a(libcairo.so.2).
ERROR:  0509-150   Dependent module /usr/lib/libXrender.a(libXrender.so.1) could not be loaded.
ERROR:  0509-152   Member libXrender.so.1 is not found in archive

I dont understand, why this happens. Do you have any idea? Some environmental info you can find below. If you need something else, let me know please.

The java code I use:

package biz;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.Collections;
import java.util.List;

public class DummyCaller {
    public static void main(String[] args) throws IOException, InterruptedException {
        printSystemProperties();
        System.out.println();
        printEnvironment();
        Process process = Runtime.getRuntime().exec( args );
        new StreamReader("OUT  ", process.getInputStream() ).start();
        new StreamReader("ERROR", process.getErrorStream() ).start();
        process.waitFor();
    }

    private static void printSystemProperties() {
        System.out.println( "System.getProperties(): " );
        List<String> keys = new ArrayList<String>();
        for (Object key : System.getProperties().keySet()) {
            keys.add( (String) key );
        }
        Collections.sort(keys);
        for (Object key : keys ) {
            System.out.println( "" + key + "=" + System.getProperty((String) key) );
        }
    }

    private static void printEnvironment() {
        System.out.println( "System.getEnv(): " );
        List<String> keys = new ArrayList<String>();
        keys.addAll(System.getenv().keySet());
        Collections.sort(keys);
        for (Object key : keys ) {
            System.out.println( "" + key + "=" + System.getenv().get( key) );
        }
    }

    public static class StreamReader extends Thread {
        private BufferedReader br;
        private String streamName;

        public StreamReader(String streamName, InputStream is ) {
            super();
            this.streamName = streamName;
            br = new BufferedReader( new InputStreamReader(is));
        }

        @Override
        public void run() {
            String line = null;
            try {
                while ( (line = br.readLine() ) != null ) {
                    System.out.println( streamName + ": " + line );
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}

It turned out, that the LIBPATH is not correct, what is passed by Java to the forked process instance.

1. Step: getting LIBPATH for Ghostscript:

After a lot of googling, i have found this:

XXXXXXXX:i2zate:/home/i2zate>dump -Hv /usr/bin/gs

/usr/bin/gs:

                        ***Loader Section***

9                                    libfontconfig.a     libfontconfig.so.1
10                                   libpng.a            libpng.so.3
11                                   libpaper.a          libpaper.so.1
12                                   libiconv.a          shr4.o
13                                   libdl.a             shr.o

Here you see the index 0 (dont ask me, what it means, it was just a guess, that I need that): /opt/freeware/lib:/opt/freeware/lib/gcc/powerpc-ibm-aix5.1.0.0/4.2.3:/opt/freeware/lib/gcc/powerpc-ibm-aix5.1.0.0/4.2.3/../../..:/usr/lib:/lib

2. Step: Passing LIBPATH in java

I changed my class slightly. The DummyCaller uses the first argument it gets as LIBPATH for the forked process. See the changed method:

public static void main(String[] args) throws IOException, InterruptedException {
    printSystemProperties();
    System.out.println();
    printEnvironment();
    String[] command = new String[ args.length - 1 ];
    System.arraycopy(args, 1, command, 0, args.length-1);
    ProcessBuilder processBuilder = new ProcessBuilder( Arrays.asList(command));
    Map<String, String> env = processBuilder.environment();
    env.put("LIBPATH", args[0] );
    Process process = processBuilder.start();
    new StreamReader("OUT  ", process.getInputStream() ).start();
    new StreamReader("ERROR", process.getErrorStream() ).start();
    process.waitFor();
}

So the first argument is added to the environment of the ProcessBuilder.

3. Step: Making the call with correct LIBPATH
