There is a complete description of the problem with the loading path of the picture in j2ME

eminentr

classpath:E:\JBuilder\jdk1.4\lib\tools.jar;E:\JBuilder\jdk1.4\lib\dt.jar;.
Project path: D:\javawork\j2me\SlideshowMidlet
Picture storage location: D:\javawork\j2me\SlideshowMidlet\
The program is written, compiled, and run in JBuilder
When running, throw an exception: Failed loading images!
The source code is as follows: (There are two classes, the running class is not posted)
import javax.microedition.lcdui.*;
import java.io.*;

public class SSCanvas extends Canvas {

    private String [] captions = {"A","B","C","D","E"};
    private int curSlide = 0;

    public SSCanvas(Display d){
        super();
        display = d;
    //The picture loader starts
        try {
            slides = new Image[5];

Pictures and source files together

eminentr

I put the picture in SRC and put it together with the source file, but it still doesn't work.

hellobaby

Try referencing the absolute path
import javax.microedition.midlet.*; add this sentence if you are doing a complete program
Image slides[0] = Image.createImage("/A.gif");
It’s no problem to put this picture and project files in one folder

conan609

gosh! What simulator do you use? I have never heard of any models that support GIF animation. You try to change to png,

awplinjie

Put the picture in the classes folder

eminentr

Thank you, everyone, the problem has been solved! ~ WTK 2.0 said that it can support GIF format pictures! But I did not consider the actual model, asconan609said, there will be no problem when changing to png format !~ And the picture should be placed in the classes file!~ Absolute path can also be used, but in that case, it will not be easy to do when publishing,! ~~`Please give me more advice in the future!~
