Question

我真的被困在这个例外3天了。它工作正常，但突然间它抛出了这个例外。

我正在尝试将用于清理的图像从我的Android设备上传到jboss中的JAVA servlet，如下所示：

 Class Servlet extends HttpServlet{

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws    ServletException, IOException {
    System.out.println("You need to post an image.");
    PrintWriter out = response.getWriter();
    out.println("Please post an image..");
    out.flush();
}

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    long time = System.currentTimeMillis();                                     // check the time, for file-naming and such
    System.out.println("Got a post - " + time);
    try{
        // get the image from the app
        ObjectInputStream ois = new ObjectInputStream(request.getInputStream());
        byte[] imageBytes = (byte[]) ois.readObject();
        PlanarImage image = ImageUtil.getAsImage(imageBytes);
        ois.close();
        System.out.println("Read image from stream...");

        // save a copy for inspection
        ImageUtil.saveImage(image, time + "_y");

        .......

ImageUtil.getasimage就像：

public static PlanarImage getAsImage(byte[] imageBytes){    
    BufferedImage bi = null;
    InputStream in = null;
    try {
        in = new ByteArrayInputStream(imageBytes);
        bi = ImageIO.read(in);
        in.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
    return PlanarImage.wrapRenderedImage(bi);                   
}

我在行

上收到以下错误

  PlanarImage image = ImageUtil.getAsImage(imageBytes);

错误：

我还下载了上述所有需要的罐子。

     import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.io.PrintWriter;
import javax.media.jai.ParameterBlockJAI;
import javax.media.jai.PlanarImage;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.usaa.ar.deconvolution.Restore;
import com.usaa.ar.util.ImageUtil;

但仍然没有运气。请帮助我，因为我无法在此例外找到任何内容。

获取java.lang.ClassNotFoundException：javax.media.jai.ParameterBlockJAI异常
