java代码
package Math; public class Box { private int length; private int width; private int height; public Box() { } public int getLength() { return length; } public void setLength(int length) { this.length = length; } public int getWidth() { return width; } public void setWidth(int width) { this.width = width; } public int getHeight() { return height; } public void setHeight(int height) { this.height = height; } }
在useBean的class报错: cannot be resolved to a type
强行运行报错
Unable to compile class for JSP:
