將tomcat註冊成服務之後竟然無法啟動了 原來是jdk1.6惹的禍 網路上的解法是將Java_home/bin中的msvcr71.dll 複製到Tomcat_home/bin/裡面,就可以正常啟動了....

If you are using Eclispe, maybe you will meet such error after you have installed a Eclipse plugin: Error retrieving "feature.xml". [error in opening zip file] When you open Help->Software Updates->Find and install to install a new plugin, this error will cause that you can not install the new one. What is the problem? Do you remember how did you install the last Eclipse plugin? I guess you download the package and unzip or just put it into Eclipse's directory, without using the Software Updates tool in Help menu in Eclipse. 1. Delete the site.xml file in your Eclipse directory. 2. Run Help->Software Updates->Find and install, the error will not appear. If the plugin has the official site, from where you can install it in Eclipse using Help->Software Updates->Find and install, I sugguest that you should not download it yourself and unzip it into your Eclipse directory. For example, EclipseMe, you can refer to http://eclipseme.org/docs/installEclipseME....

到 tomcat_home/conf/server.xml 中修改兩個地方 1. <Server port="8005" shutdown="SHUTDOWN" debug="0"> 預設是 8005，你可以調整成 8006, 8007, ...。 2. <Connector port="8080" .../> ，你必須用不同的 port 才行。

在commamd line 中下 [ netstat -ano ] 命令 在local address欄位中找到被佔用的 port 跟在 pid 欄位中找到對應的 process id 按 Ctrl+Alt+Del 叫出工作管理員，按下處理程序 tab，在[檢視]-->[顯示欄位]中勾選pid才會顯示pid欄位，這樣就可以知道是誰幹的好事了! 找不到pid的話試著去勾選下面有個 [顯示來自所有使用者的處理程序] 吧!

跟simpleform controller一樣,先在xml中設定好validator 只要validator的support有支援到在multiaction controller中的command的時候 就會採用該valiodator 接下來新增一個MyMultiacitonController 擴展原本的multiaction controller public class MyMultiactionController extends MultiActionController { //用來儲存binding error的model private Map errorModel = null; //以下是修改原始程式碼的結果 @Override protected void bind(HttpServletRequest request, Object command) throws Exception { logger.debug("Binding request parameters onto MultiActionController command"); ServletRequestDataBinder binder = createBinder(request, command); binder.bind(request); if (getValidators() != null) { for (int i = 0; i if (getValidators()[i].supports(command.getClass())) { ValidationUtils.invokeValidator(getValidators()[i], command, binder.getBindingResult()); } } } if (binder.getBindingResult().hasErrors()) { setErrorModel(binder.getBindingResult().getModel()); } } public Map getErrorModel() { Map map = this.errorModel; this.errorModel = n...
