Ghostscript在命令行中工作，但如果在AIX上从Java执行则不起作用
简短的介绍
我必须在AIX上运行Ghostscript。 它在命令行中工作 ：

我不明白，为什么会这样。 你有什么主意吗？ 您可以在下面找到一些环境信息。 如果您需要别的东西，请告诉我。
更深入的信息
我使用的java代码 ：
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 keys = new ArrayList(); 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 keys = new ArrayList(); 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(); } } } }

事实certificate， LIBPATH不正确，Java传递给分叉流程实例。
1.步骤：获取Ghostscript的LIBPATH：
经过大量的谷歌搜索，我发现了这个：
XXXXXXXX:i2zate:/home/i2zate>dump -Hv /usr/bin/gs /usr/bin/gs: ***Loader Section*** Loader Header Information VERSION# #SYMtableENT #RELOCent LENidSTR 0x00000001 0x00000137 0x00008118 0x000001ad #IMPfilID OFFidSTR LENstrTBL OFFstrTBL 0x0000000e 0x00062a68 0x00000e99 0x00062c15 ***Import File Strings*** INDEX PATH BASE MEMBER 0 /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 1 libc.a shr.o 2 libpthread.a shr_comm.o 3 libpthread.a shr_xpg5.o 4 libXt.a shr4.o 5 libX11.a shr4.o 6 libcairo.a libcairo.so.2 7 libjpeg.a libjpeg.so.62 8 libz.a libz.so.1 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
在这里你看到索引0（不要问我，它意味着什么，它只是一个猜测，我需要它）：/ opt / freeware / lib ：/ opt / freeware / lib / gcc / powerpc-ibm-aix5.1.0 0.0 / 4.2.3：/opt/freeware/lib/gcc/powerpc-ibm-aix5.1.0.0/4.2.3 /../../..:/ usr / lib目录：/ lib目录
2.步骤：在java中传递LIBPATH
我稍微改变了我的课程。 DummyCaller使用它获取的第一个参数作为分叉进程的LIBPATH。 请参阅更改的方法：
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 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(); }
因此，第一个参数被添加到ProcessBuilder的环境中。
3.步骤：使用正确的LIBPATH拨打电话
