问题描述
我写好了一applet类，效果是动态显示一张图片，在eclipse中直接runasapplet能出结果。但，加到前台后，图片出不来。、这是前台代码：//index.jsp<appletcode="ScrollImage.class"width="150"height="100"><paramname="Image"value="L.jpg">Sorry,yourbrowserdoesn'tsupportJava(tm).</applet>如果我把这个index.jsp改成index.html，双击就能直接正确的运行出来。这是怎么回事？？？？诚望赐教！！！具体报错如下：L.jpg已载入图象：http://127.0.0.1:8080/MyApplet/L.jpg-1,-1java.lang.IllegalArgumentException:Width(-1)andheight(-1)cannotbe<=0atjava.awt.image.DirectColorModel.createCompatibleWritableRaster(UnknownSource)atsun.awt.Win32GraphicsConfig.createAcceleratedImage(UnknownSource)atsun.awt.windows.WComponentPeer.createImage(UnknownSource)atjava.awt.Component.createImage(UnknownSource)atScrollImage.init(ScrollImage.java:68)atsun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(UnknownSource)atjava.lang.Thread.run(UnknownSource)异常：java.lang.IllegalArgumentException:Width(-1)andheight(-1)cannotbe<=0java.lang.NullPointerExceptionatScrollImage.start(ScrollImage.java:80)atsun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(UnknownSource)atjava.lang.Thread.run(UnknownSource)异常：java.lang.NullPointerExceptionL.jpg已载入图象：http://127.0.0.1:8080/MyApplet/L.jpg-1,-1java.lang.IllegalArgumentException:Width(-1)andheight(-1)cannotbe<=0atjava.awt.image.DirectColorModel.createCompatibleWritableRaster(UnknownSource)atsun.awt.Win32GraphicsConfig.createAcceleratedImage(UnknownSource)atsun.awt.windows.WComponentPeer.createImage(UnknownSource)atjava.awt.Component.createImage(UnknownSource)atScrollImage.init(ScrollImage.java:68)atsun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(UnknownSource)atjava.lang.Thread.run(UnknownSource)异常：java.lang.IllegalArgumentException:Width(-1)andheight(-1)cannotbe<=0java.lang.NullPointerExceptionatScrollImage.start(ScrollImage.java:80)atsun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(UnknownSource)atjava.lang.Thread.run(UnknownSource)异常：java.lang.NullPointerException
