Jython & Mysql - what is the current practice for connection? -


Just trying for the first time, because something came on the job that was right for it. I think mythsql can make a jdbc connection using mythsql jdbc driver. Googling and after reading, though I'm having trouble and it seems Jyothan-specific and perhaps simple. So I do Jyothon: 

  Geothan 2.5.1 (Release_2_5_1: 6813, September 26, 13:47:54) [Java Hotspot (TM) 64-bit server VM (Apple Inc.)] For more information on Java1.6.0_17, type "help", "copyright", "credit" or "license". & Gt; & Gt; & Gt; Import systems and gt; & Gt; & Gt; Print sys.path [ ',' /JYTHONPATH/mysql-connector-java-5.1.10-bin.jar ',' /WorkArea/Apps/jython/jython2.5.1/Lib ',' __classpath__ ',' __pyclasspath __ / ' , '/WorkArea/Apps/jython/jython2.5.1/Lib/site-packages'] & gt; & Gt; & Gt; Java.sql to java.lang import *,

I'm running the code 

  "JDBC: mysql: // local host / test user = jgreenaw & password =" import * drivername = "com.mysql.jdbc.Driver" Class.forName (drivername) url = thief = DriverManager.getConnection (URL) Stmt = thief .createStatement ()

Output 

  riux: Desktop $ jython pymysql Py traceback (most recent call final): file "pymysql.py", line 7, & lt; Module & gt; Class.forName (drivername) java.security.AccessController.doPrivileged (Native Method on java.net.URLClassLoader $ 1.run (URLClassLoader.java:200)) java.net.URLClassLoader.findClass (URLClassLoader.java:188) on Java.lang.ClassLoader.loadClass (ClassLoader.java:315) on sun.misc.Launcher $ AppClassLoader.loadClass (Launcher.java:330) on java.lang.ClassLoader.loadClass (ClassLoader.javaociety50) on java.lang Classloader on Java.lang.Class.forName0 (Native Method) Load Class Inarl (Clasloderkjawa 398) sun.ref.nl.eng.lang.Class.forName (class.java:169) on SunkreflectkNativeMethodAccessorImplkinvoke0 (Basic Law) SunkreflectkNativeMethodAccessorImplkinvoke ( NativeMethodAccessorImpl.java:39) .ClassNotFoundException on java.lang on sun.reflect.DelegatingMethodAccessorImpl.invoke (DelegatingMethodAccessorImpl.java:25) java.lang.reflect.Method.invoke (Method.java:597): java.lang.ClassNotFoundException : com. Mysql.jdbc.Driver

Any advice?

Thank you

Do you have the right to read this? Try opening it in your code as a file Also check if this file is valid jar collection containing com / mysql / JDBC / Driver.class .

I can do this when I use PostgreSQL on Windows to check with: 

  import zipfile def test_jar (jar_file, CLASS_NAME): zf = zipfile.zipfile (Jar_file, 'r') cn = class_name.replace ('.', '/') + '.class' zi = zf.getinfo (cn) Print ('% s:% s [b] - & gt;% c [B]% (Zikfilenme, Zikfail_saij, Zikkanpres_saij)) Test_jar ( 'a: /jars/postgreskl-8k3-603kjbk4kjar' Orgkpostgresklkdraivr ')

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
