Developers who are new to MTK always think that their work is boring and promising. They change bugs all day long. In fact, this idea is narrow. MTK learning can only be regarded as the tip of the iceberg in the embedded field, we should thank him for reducing the embedded threshold. All others say that the software development language is the same. Similarly, the development of embedded systems is the same, and embedded systems are also the same, other systems can be quickly mastered and develo

. getsession ();Return (mapping. findforward ("success "));}} You only need to define a base class without additional code work. The above solution is elegant and effective. In any case, writing a common behavior method as a base class that inherits strutsaction is a common experience of many struts projects and is recommended. LimitationsThe above solution is very simple and practical for JSP or struts-based Web applications, but it still has s

Three-day Dragon Boat Festival holiday, I learned jruby and groovy. At last I thought groovy was easy to use. Using groovy is a bit like writing basic, and there are no more rules like Java. During development, code is used to describe the execution logic, rather than writing a large number of classes that comply with Java "patterns" to implement certain logic functions. Groovy gives me the feeling that there are two words "elegant". In terms of codin

Later I made a "strange" extension for another project: For example, we know that in the print settings, we can directly write the number of pages to filter which pages to print-1, 4, 9, or 1-8. This raises the following requirements: Query orders of Bruce and jeffz on the left, and query orders of B until Z on the right.

process specified by the pid. In some cases (for example, if the process is already hang and cannot respond to normal signals), kill-9 can be used to end the process. If a Process terminated by kill is a parent Process that has created a child Process, the child Process will become an Orphan Process. in this case, the exit status of the sub-process cannot be captured by the application process (because the application as the parent process does not exist), but it should not adversely affect the
