To learn web service, we need to learn WSDL. This xml file defines the services that we deploy in our web service.
Here, we get  a  example of WSDL.

 So many infomations in this file. But first of all, we need to understand the format of this file.
To me, the defination of namespace is a problem.

My qustions are: For xmlns, xmlns:tns1,xmlns:intf..., What do they mean? How to use them?


After I refered to some articles in internet. I get the answer:
每個(gè)namespace屬性都聲明了一個(gè)縮略語，用在文檔中。例如"xmlns:xsd"就為
But I get another question that no one reply.

'我們都知道，WSDL應(yīng)該是格式正確的XML文檔。進(jìn)一步，還應(yīng)該把它看作一個(gè)Schema，因此，<definitions>元素中可以定義targetNamespace屬性，表示在這個(gè)元素下的所有元素都屬于這個(gè)目標(biāo)名稱空間。

xmlns表示缺省的名稱空間，...'

So what's difference between 'targetnamespace' and default 'xmlns'?

現(xiàn)在正在做的項(xiàng)目中，就有undo、redo的操作。使用的是java本身的undoManager。但是因?yàn)槭褂玫牡谌杰浖呀?jīng)把它封裝過了，所以用起來并不是直接使用java的undomanager。其間，遇到這樣的問題：有些操作不想被undo所管理，但是圖形上的變換卻總是會(huì)被listener加入到undo的edits中。想了很多辦法，包括繼承再封裝undomanager將edits傳出來保存，需要恢復(fù)的時(shí)候再設(shè)進(jìn)去、discard所有的edits、找尋第三方軟件封裝undoableEdit的方法，以使得操作不被undo....最后，用最簡單的方法解決問題：設(shè)置一個(gè)boolean變量,然后重載listener的方法，用這個(gè)變量來控制是否調(diào)用super.undoableEditHappened即可。 唉，真笨啊，用這么簡單的問題都能解決的，搞了老半天... ---------------------------- A ja A ja, fighting fighting

load進(jìn)一個(gè)圖片，如果對(duì)它進(jìn)行放大縮小呢？ 查找了很多地方的資料，找到以下的方法可以解決放大縮小圖片問題： public static ImageIcon imageIconZoom(ImageIcon orgImageIcon, int newWidth, int newHeight) { BufferedImage tag = new BufferedImage(newWidth, newHeight, BufferedImage.TYPE_INT_ARGB); tag.getGraphics().drawImage(orgImageIcon.getImage(), 0, 0, newWidth, newHeight, null); return new ImageIcon(tag); } 如何對(duì)圖片著色呢？ static final float CRITICAL_BAND_MATRIX[][] = { { 1.0f, 0.0f, 0.0f , 0.0f}, { 0.0f, 0.0f, 0.0f , 0.0f}, { 0.0f, 0.0f, 0.0f,0.0f }, { 1.0f, 0.0f, 0.0f, 0.0f } }; static final float MAJOR_BAND_MATRIX[][] = { { 1.0f, 0.0f, 0.0f , 0.0f}, { 0.0f, 0.5f, 0.0f, 0.0f }, { 0.0f, 0.0f, 0.0f , 0.0f}, { 1.0f, 0.5f, 0.0f, 0.0f } }; static final float MINOR_BAND_MATRIX[][] = { { 1.0f, 0.0f, 0.0f , 0.0f}, { 0.0f, 1.0f, 0.0f , 0.0f}, { 0.0f, 0.0f, 0.0f, 0.0f } , { 1.0f, 1.0f, 0.0f, 0.0f }}; static final float WARNING_BAND_MATRIX[][] = { { 0.5f, 0.0f, 0.0f , 0.0f}, { 0.0f, 0.0f, 0.0f , 0.0f}, { 0.0f, 0.0f, 1.0f , 0.0f} , { 0.5f, 0.0f, 1.0f, 0.0f }}; static final float CLEAR_BAND_MATRIX[][] = { { 0.0f, 0.0f, 0.0f, 0.0f }, { 0.0f, 1.0f, 0.0f, 0.0f }, { 0.0f, 0.0f, 1.0f, 0.0f }, { 0.0f, 1.0f, 1.0f, 0.0f } }; static final float UNKNOWN_BAND_MATRIX[][] = { { 0.0f, 0.0f, 0.0f, 0.0f }, { 0.0f, 0.0f, 0.0f , 0.0f}, { 0.0f, 0.0f, 1.0f, 0.0f } , { 0.0f, 0.0f, 1.0f, 0.0f }}; public static ImageIcon ColorImage(ImageIcon orgImage, int alarmStatus ){ float[][] targetMatrix ; switch(alarmStatus){ case CommonConstants.ALARM_UNKNOWN: targetMatrix = UNKNOWN_BAND_MATRIX; break; case CommonConstants.ALARM_CLEAR: targetMatrix = CLEAR_BAND_MATRIX; break; case CommonConstants.ALARM_MINOR: targetMatrix = MINOR_BAND_MATRIX; break; case CommonConstants.ALARM_MAJOR: targetMatrix = MAJOR_BAND_MATRIX; break; case CommonConstants.ALARM_CRITICAL: targetMatrix = CRITICAL_BAND_MATRIX; case CommonConstants.ALARM_WARNING: targetMatrix = WARNING_BAND_MATRIX; break; default: targetMatrix = UNKNOWN_BAND_MATRIX; } BufferedImage b1 ; BufferedImage biSrc = new BufferedImage(orgImage.getIconWidth(), orgImage.getIconHeight(), BufferedImage.TYPE_INT_ARGB); // biSrc.getGraphics().setColor(Color.white); // biSrc.getGraphics().fillRect(0, 0, orgImage.getIconWidth(), orgImage.getIconHeight()); biSrc.getGraphics().drawImage(orgImage.getImage(),0,0,null); BufferedImage biTar = new BufferedImage(orgImage.getIconWidth(), orgImage.getIconHeight(), BufferedImage.TYPE_INT_ARGB); Raster srcRaster = biSrc.getRaster(); WritableRaster dstRaster = (WritableRaster) biTar.getRaster(); BandCombineOp bandCombineOp = new BandCombineOp(targetMatrix, null); bandCombineOp.filter(srcRaster, dstRaster); b1 = biTar; return new ImageIcon(b1); } 其中值得一說，卻又說不清楚的地方是：BufferedImage.TYPE_INT_ARGB， 為什么要用TYPE_INT_ARGB，而不用TYPE_INT_RGB，之前我是用的TYPE_INT_RGB，而且matrix也是3*3的一個(gè)矩陣，后來發(fā)現(xiàn)，著色前，圖片透明的地方，著色后，變成了黑色的了，于是猜想ARGB中的A應(yīng)該是alphe的意思，就摸索構(gòu)造了矩陣，并且著了實(shí)驗(yàn)，用是能用，不知道對(duì)不對(duì)啊。。。。

從事java開發(fā)兩三年了，感覺技術(shù)上提高很難了，希望能夠在這個(gè)地方尋找到突破口。
