There was a strange problem with the three-tier Web project. I set the object parameter through Session.setattribute in the user login servlet (login), in theory, after the successful login, the parameter is passed successfully, and the value of the object parameter can be obtained through session.getattribute in other servlets, but it is nul L value, test a lot of times are not, searched a lot of information and did not find the problem. What session expires, what TTOMCAT configuration file mod

Recently done in the Windows XP x64,vs2005 environment to do 32-bit programs to compile the work of 64-bit programs, encountered some of the 64-bit programming may encounter problems: such as inline assembly (the solution is changed to C + + code), a long type of change, The most critical issue is encountering a 64-bit process that requires calling a 32-bit DLL. Because some 32-bit DLLs do not have source code, can not be recompiled to a 64-bit DLL, s

single-piece mode implementation has been able to meet basic usage requirements, but when the single-mode mode encounters multiple threads, many strange problems occur (in fact, many of the code is problematic after encountering multiple threads).For example, in the example above, the problem occurs when the code is in a state like the following:This time the object is not the same, multithreading causes the single-piece mode is not the same as our d

The authentication mechanism is the central mechanism for the application to defend against malicious attacks. It is at the forefront of the defense's unauthorized, and if users can break through those defenses, they can usually control the full functionality of the application and freely access the data. Lack of security and stability of the authentication mechanism, other core security mechanisms (such as reply management and access control) can not be effectively implemented.Common validation

For the practical use of machine learning. It is not enough to know the level of light, and we need to dig deeper into the problems encountered in the practical. I'm going to make a tidy up of some trivial knowledge points.1 Data imbalance issuesThis problem is often encountered.Take a supervised study of the two classification problem. We need the annotations of both positive and negative examples. Assuming we get the training data are very few negat

Many of the core Java face questions come from multithreaded (multi-threading) and collection frameworks (collections framework), which are required to understand the core threading concepts. This article collects some typical Java threading problems that are often asked by senior engineers. 0. What is multithreaded synchronization in Java? Synchronization can control access to shared resources under multithreaded routines. If there is no synchroniz

Here is a note of the problems that were encountered before using the entity Framework (4.3.1 version). Update table with no primary key set By default, the EF cannot update, insert, and delete a table that does not have a primary key. Viewing the edmx file in XML, you can see the following XML fragment in SSDL (I've defined a table Tb_withoutkey without a primary key). Copy Code code as follows: SELECT [Tb_withoutkey]. [ID] as [ID
