我正在尝试调用位于jar文件中的"dspdf.exe",它与smartpdf类位于同一位置。我计划将其提取到临时位置,并在程序结束时删除。然而,这似乎无法实现,希望能得到帮助。
编辑: 我遇到的错误:
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import org.omg.CORBA.portable.InputStream;
public class smartpdf {
static String url="";
static String output="output.pdf";
public static void main(String[] args) throws IOException{
gui mygui = new gui();//gui will call the generate function when user selects
}
public static void generate() throws IOException{
InputStream src = (InputStream) smartpdf.class.getResource("dspdf.exe").openStream();
File exeTempFile = File.createTempFile("dspdf", ".exe");
FileOutputStream out = new FileOutputStream(exeTempFile);
byte[] temp = new byte[32768];
int rc;
while((rc = src.read(temp)) > 0)
out.write(temp, 0, rc);
src.close();
out.close();
exeTempFile.deleteOnExit();
Runtime.getRuntime().exec(exeTempFile.toString()+" "+url+" "+output );
//Runtime.getRuntime().exec("dspdf "+url+" "+output);
}
}
