帶進度條的文件上傳(java+ajax源碼) 在寫代碼的時候，還要用到關于servlet的包servlet-api.jar。 寫完后調試的過程中，老報錯：java.lang.NoClassDefFoundError: org/apache/commons/io/output/DeferredFileOutputStream，后來一查才知道少了commons-io-1.2.jar，加上后，就ok了。 關于獲取及顯示進度部分，用了我原來自己寫的一個ajax的應用架構，從中抽取了部分代碼出來，注意，js文件只適用于UTF-8編碼的頁面，因為現在我只寫UTF-8編碼的頁面了，國際化方便。 progressUpload.jar中，包含了commons-fileupload-1.1.1.jar，servlet-api.jar，commons-io-1.2.jar，在progressUpload.jar中，還包含一個屬性文件，里面是一些默認配置，可根據自己的需要修改。 由于有源碼，怎么用可以自己看源碼，此外，那個例子中也寫了，在此不再贅述。例子中只取到了FileItem，再將item保存一下就ok了，示例代碼： File upFile = new File(remoteFilePath) try \{ item.write(upFile) fileInfo.put("infotip", "上傳成功.") } catch (java.lang.Exception e) \{ fileInfo.put("infotip", "上傳失敗.") }

The LM158 series consists of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage.

采用jsp+servlet+javabean，jsp負責少量的頁面處理，以servlet為主。 結構清晰明了，未對頁面做美工處理，因此html和javascript代碼很少， 非常適合作為java入門的例程，特別是對servlet部分。 開發調試平臺為jbuilder9+tomcat4，在resin下測試通過。 數據庫平臺為ms sql server，在mysql下測試通過，但要改部分代碼 數據庫連接池為apache組織下jakarta項目組開發的commons-dbcp 1.0

A general technique for the recovery of signi cant image features is presented. The technique is based on the mean shift algorithm, a simple nonparametric pro- cedure for estimating density gradients. Drawbacks of the current methods (including robust clustering) are avoided. Feature space of any nature can be processed, and as an example, color image segmentation is dis- cussed. The segmentation is completely autonomous, only its class is chosen by the user. Thus, the same program can produce a high quality edge image, or pro- vide, by extracting all the signi cant colors, a prepro- cessor for content-based query systems. A 512 512 color image is analyzed in less than 10 seconds on a standard workstation. Gray level images are handled as color images having only the lightness coordinate

ava 項目中，當需要高性能上傳文件時，往往就需要依靠組件，而不是手寫的servlet了，一般的選擇包括jakarta commons-fileupload以及smartupload，由于后者在上傳大文件時往往會出錯，另外對中文支持一般，筆者采用了前者。

These two classes show an extremely simple example of java.net socket programming. They implement the Unix daytime protocol, an extremely simple protocol that consists entirely of the server sending its current local time and date to the client as an ASCII string. The server, to keep it very simple, does not use multiple threads. This code requires JDK 1.1 or later, but can easily be adapted to JDK 1.0.
