pdf转换为swf,cannot open pdf文件

pdf转换为swf,cannot open pdf文件

在window7上部署的项目，可以正常由pdf转换为swf，但在linux上部署的项目，却报以下错误：
cannot open pdf文件，代码： // 先生成flash 
        String[] envp = new String[1]; 
        envp[0] = "PATH=/app/bin/"; 
        String command = "pdf2swf -z -s flashversion=9 \"" + sourcePath+ "\" -o \"" + destPath + fileName + "\""; 
        System.out.println("pdf command--------------------------------------------------------"+envp[0]+"=="+command);
        System.out.println(command); 
        int exitValue =0;
        Process pro = Runtime.getRuntime().exec(command);
        try{ 
pro = Runtime.getRuntime().exec(command);
InputStreamReader ir=new
InputStreamReader(pro.getInputStream());
          
BufferedReader input = new BufferedReader (ir);
          
String line;
          
while ((line = input.readLine ()) != null){    
System.out.println(line);
}//end try
exitValue = pro.exitValue();
      
} catch (java.io.IOException e){        
System.err.println ("IOException " + e.getMessage());
}

linux 上的java程序拼出来的系统命令中去掉双引号，即：
把String command = "pdf2swf -z -s flashversion=9 \"" + sourcePath+ "\" -o \"" + destPath + fileName + "\"";
改成如下一句
String command = "pdf2swf -z -s flashversion=9 " + sourcePath+ " -o " + destPath + fileName;
