确认访问源文件的方法正确吗？最好把所有的exception信息都贴出来，这样才好找问题。Top

我考，还是写错了
//调用的jsp程序 （对不起）
james.cmb.ImgBean_i bbb= new james.cmb.ImgBean_i();
bbb.ImgYin("/photo/images/shuiyin.gif","/photo/upfile/" + newname);

晕菜，给你临时写一个：
import javax.imageio.ImageIO;
import java.io.File;
import java.awt.Component;
import java.awt.MediaTracker;
public class TestImage extends Component{
public static void main(String[] args) throws Exception{
TestImage ti = new TestImage();
Toolkit toolkit = Toolkit.getDefaultToolkit();
Image im = toolkit.getImage("197.jpg");
try {
MediaTracker tracker = new MediaTracker(ti);
tracker.addImage(im, 0);
tracker.waitForID(0);
} catch (Exception e) {
System.out.println(e.getMessage());
}
BufferedImage image = new BufferedImage(im.getWidth(ti), im.getHeight(ti), BufferedImage.TYPE_INT_RGB);
Graphics graphics = image.getGraphics();
graphics.drawImage(im, 0, 0, ti);
graphics.setFont(new Font("Courier New", Font.BOLD, 72));
graphics.drawString("I'l kill you!", 80, 80);
File f = new File("test.jpg");
ImageIO.write(image, "jpg", f);
}
}Top
