试用Netbeans5.5

EdwinWang — Thu, 21 Dec 2006 03:10:00 GMT

今天��试了下Netbeans 5.5版本�Q�个人感觉很不错。一直都不太喜欢Eclipse�Q�也许Eclipse�l�开发�h员带来了最灉|��的IDE�Q�可灉|��是有代�h的，装个其他开发环境大概十��C��十分钟就好了�Q�装Eclipse加上捣鼓那些插�g估计能搞上一天�?br />试了下在Netbeans5.5下开发Swing,web,web service,JSF�{�一些功能，感觉�q�不错。虽然一些图形化的拖拉效果做的还不尽如�h意，但已�l�很不错了。据说还可以可视化开发Mobile�E�序�Q�改天要试一下�?br />虽然Netbeans的灵�z�L��不如eclipse,但是功能�q�是很强大的�Q�值得使用。个人感觉eclipse更适合玩IDE的�h而不是用IDE的�h使用。Just 个�h意见�Q�呵呵～�?img src ="http://www.aygfsteel.com/EdwinWang/aggbug/89229.html" width = "1" height = "1" />

如何在JAVA�E�序中调用windows其他�E�序

EdwinWang — Wed, 20 Dec 2006 02:49:00 GMT

虽然JAVA是��^台无��x��的�Q�但是在企业中很多时候还是在为特定的�pȝ��在开发，会要求调用一些当前系�l�的其他�E�序或命令。最常见的是在WINDOWS中。其实JAVA是可以通过Runtime去调用系�l�中的一些程序的�Q�下面是一个例子：

try {
            ps = Runtime.getRuntime().exec( " E:\\test.exe " );
             // ps = Runtime.getRuntime().exec("ipconfig");  ---- For execute windows commands
             // ps = Runtime.getRuntime().exec("E:\\test.bat"); ---- For run BAT files
            BufferedReader in = new BufferedReader( new    InputStreamReader(ps.getInputStream()));
            String inputLine;
             while ((inputLine    =    in.readLine())    !=     null ) {
                result    +=    inputLine + " \n " ;
            }
            in.close();
            System.out.println( " Output: " + result);

        } catch (Exception ex) {
            System.out.println( " Error " + ex.getMessage());
        }

上面的代码片断中后面一部分是在取返回的参数�Q�如果不需要可以不取。不取的话可能也��׃��需要取得到Process了。用�q�个�Ҏ��可以�q�行windows中的exe或者bat文�g�?img src ="http://www.aygfsteel.com/EdwinWang/aggbug/88991.html" width = "1" height = "1" />

手动SOAP Call WebService

EdwinWang — Tue, 19 Dec 2006 01:40:00 GMT

前不久公司接了个�z�，要求在Pnuts中Call WebService�Q�本来是一件很�Ҏ��的事�Q�可不能��d��W�三方的�c�d��l�我造成了麻烦。不能��用Ajax�{�一些第三方的包�Q�意味着我只能自己去解析SOAP协议�Q�而在PNuts中虽然可以调JAVA的方法，但却不适合写很大的功能�Q�最后采用了一�U�非常傻的做法，手动��L��SOAP消息的内容，写在�q�作为对一些特�D�需求的一�U�实现方式：

try {
    postStr = postStr + " " ;
    postStr = postStr + " " ;
    postStr = postStr + " xmlns:xsd='http://www.w3.org/2001/XMLSchema' " ;
    postStr = postStr + " xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/'> " ;
    postStr = postStr + " " ;
    postStr = postStr + " " ;
    postStr = postStr + " Test " ;
    postStr = postStr + " 35b82957-c792-81ce-38e4-7c83ad3291ea " ;
    postStr = postStr + " Test_Get_Data " ;
    postStr = postStr + " " ;
    postStr = postStr + htmlEncode(data);
    postStr = postStr + " " ;
    postStr = postStr + " " ;
    postStr = postStr + " " ;
    postStr = postStr + " " ;

    URL url = new URL( " https://www.test.com/testdata.php " );
    HttpURLConnection conn = (HttpURLConnection)url.openConnection();
    conn.setDoOutput( true );
    conn.setRequestMethod( " POST " );
    conn.setRequestProperty( " Content-Type " , " text/xml " );
    conn.setRequestProperty( " Content-Length " , String.valueOf(postStr.length()));
    conn.setDoOutput( true );
    conn.setDoInput( true );
    conn.connect();
    PrintWriter out = new PrintWriter(conn.getOutputStream());
    out.print(postStr);
    out.flush();
    out.close();
    BufferedReader in = new BufferedReader( new    InputStreamReader(conn.getInputStream()));
    String inputLine;
     while ((inputLine    =    in.readLine())    !=     null ) {
        result    +=    inputLine + " \n " ;
    }
    in.close();
    System.out.println(htmlDecode(result));
} catch (Exception ex) {
    System.out.println( " Error: " + ex.getMessage());
}
