问题 how to load the mysql server in android emulator i.e Class.forName("com.mysql.jdbc.Driver") i got the exception java.land.ClassNotFoundException in com.mysql.jdbc.Drive please reply me. 回答1: This assumes MySQL is publicly available from internet, but it is never good idea . Setup public WebService and connect to it from mobile application. 回答2: You won't be able to run MySQL server on an Android device. What you're doing, however, is trying to load the MySQL client library. That isn't

问题 I have installed MongoDB service in my Centos 6 cloud server. Now i need to install in my server php-pecl-mongo-1.2.10-1.el6.remi.x86_64.rpm... but it gives "packages not found". Can anyone fix this problem? My php version is PHP 5.3.3. I am using putty for configuring Centos 6 server. I have admin privilege to configure php.ini. 回答1: You could: try RPM installing php-pecl-mongo without a specific version point to a specific RPM url for installation, eg. using rpmfind.net => php-pecl-mongo

问题 We are using the Oracle JDBC driver version 9.0.2.0.0 and are having some trouble concerning saving CLOBs to the database. (method clob.setCharacterStream(0); throws an UnsupportedFeatureSqlException . I think this is because of the old version... Is it save to switch to the newest 10g driver? (We are using a database of version 10). Or could that cause any problems in our existing queries? 回答1: If you're using version 10 of the DB, I'd definitely use the 10g JDBC drivers. In fact, and ISTBC,

问题 I am working with the Zynq 7 of Xilinx. On the Zynq there is a FPGA, an ARM processor and 512 MiB of DDR RAM. When the board is powered on, the ARM processor starts Ubuntu, which initializes the DDR RAM and claims it as its own. On the FPGA, I am developping another processor and I want to give it a piece of DDR memory. Since I am still developing, I would like to somehow allocate a piece of 64 MiB of continous DDR RAM from linux userspace (the device has a MMU). I would then get the start

问题 I'm writing a kernel driver, which should read (and in some cases, also write) some memory addresses in kernel session space (win32k.sys). I've read in another topic that for example in Windbg I should change the context to a random user process to read the memory of kernel session space (with .process /p). How can I do that in a kernel driver? Should I create a user process which communicate with the driver (that's my idea now, but I hope that there is a better solution) or there is a more

问题 I am trying to connect to a sqlite database from Java. I am programming in Windows. I downloaded the sqlite driver and set the classpath in the windows environment variables. I get a classNotFoundException when this code is called: Class.forName(sDriver); where sDriver is "org.sqlite.JDBC" Here is the stacktrace from the exception: java.lang.ClassNotFoundException: org.sqlite.JDBC at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java

问题 The description at this - http://www.tldp.org/LDP/lkmpg/2.4/html/x281.htm - page (as well as some related answers on SO, for example the answer here - __init and __exit macros usage for built-in and loadable modules ) says The __init macro causes the init function to be discarded and its memory freed once the init function finishes for built-in drivers, but not loadable modules. However, I tried to insert the following module, in which I try to call the init functions with __init attribute

问题 I built a new Windows CE image and placed two USB drivers. One for the USB printer and the second for some special device with digital and analog I/O ports. I have one problem that came out with the drivers while the operating system boots up. Every time the image boots up it asks to enter the driver's name. (The message is "Unidentified USB Device" Enter the name of the USB device driver) Is there a workaround for this problem ? What does I have to put into a registry? I did not check if the

问题 I'm writing some documentation on how to connect Access to SQL via ODBC. I honestly always just choose "11.0" when it comes to drivers, just because. But I'm wondering what determines the driver I "should" be using? Does the version of SQL Server determine this? And I'm assuming the "User's" computer won't have all the driver's I'm seeing here so can someone just clarify the rules to choosing the correct driver? 回答1: According to a blog post located here, SQL Native Client was introduced in

问题 I'm on a 13" MacBook Pro (model 7,1. Mid-2010) and I recently installed Ubuntu 12.04 LTS. Essentially what I'm trying to do is make a program that invokes the right-click menu when a user clicks the bottom right corner of the Mac trackpad. The main issue here is detecting where exactly the user's position on the trackpad is . Of course, this is rather easy to do in OSX using NSTouch : - (void)touchesBeganWithEvent:(NSEvent *)event { NSSet *touches = [event touchesMatchingPhase
