swf如何从jsp页面中获取一个字符？？
我的问题是：对flash不懂，就用了个现成的makepic.swf，现在我想让swf在点击“上传”按扭时，从a.jsp中取得一个字符串并把这个字符串同图像一块上传到接收的b.jsp中，作为保存图像的文件名！那么我在a.jsp中如何做才能让makepic.swf得到这个字符串？
makepic.swf中的脚本
- JScript code
// Action script...// [onClipEvent of sprite 36 in frame 1]//Component construct(){ icon = ""; label = "上 传"; labelPlacement = "right"; selected = false; toggle = false; enabled = true; visible = true; minHeight = 0; minWidth = 0;}onClipEvent (load){ function __f_click(eventObj) { this._parent.send_me(); } // End of the function this.addEventListener("click", __f_click);}// [onClipEvent of sprite 36 in frame 1]//Component construct(){ icon = ""; label = "预 览"; labelPlacement = "right"; selected = false; toggle = false; enabled = true; visible = true; minHeight = 0; minWidth = 0;}onClipEvent (load){ function __f_click(eventObj) { this._parent.view_me(); } // End of the function this.addEventListener("click", __f_click);}// [onClipEvent of sprite 81 in frame 1]on (press){ startDrag("", true);}on (release, releaseOutside){ stopDrag();}// [Action in Frame 1]function changeFrontImg(picPath){ _root.pic.loadMovie(picPath);} // End of the functionflash.external.ExternalInterface.addCallback("changeFrontImg", this, changeFrontImg);function print_me(){ var _l3 = ball._x - 65; var _l2 = ball._y - 83; pn = new it.sephiroth.PrintScreen(); pn.addListener(listener); pn.print(_root, 0, 0, img_w, img_h, _l3, _l2); loader.__set__label("输出中... 0%"); loader.open(false, true, true);} // End of the functionfunction view_me(){ var _l3 = ball._x - 65; var _l2 = ball._y - 83; pn = new it.sephiroth.PrintScreen(); pn.addListener(listener); pn.view(_root, 0, 0, img_w, img_h, _l3, _l2);} // End of the functionfunction send_me(){ pn = new it.sephiroth.PrintScreen(); pn.addListener(listener); pn.send(_root, 0, 0, img_w, img_h, 225, 5); loader.__set__label("输出中... 0%"); loader.open(false, true, true);} // End of the functionmyCam = Camera.get();myCam.setMode(440, 660, 10, true);my_video.attachVideo(myCam);var loader = this.createClassObject(it.sephiroth.mloaderWindow, "loader", 10, {_x: -1000, _y: -1000});var listener = new Object();var img_w = 130;var img_h = 165;listener.onProgress = function (target, loaded, total){ var _l1 = Math.round(loaded / total * 100); loader.__set__label("Sending...

[解决办法]
借助js,与
flash.external.ExternalInterface.addCallback("changeFrontImg", this, changeFrontImg);
