In the Java EE application development, the application and the database connection establishment is one of the problems that we often encounter. Here I talk about connecting Oracle databases through OCI, thin, and jdbcodbc bridges in local applications, iplanet Application Server 6.5 and Sun one application server 7 The configuration of the Oracle database conne

Collector and service functions, and the HotSpot runtime compiler and the mixed runtime system. In the podcast, Reinhold also mentioned the modular feature of JDK 7, which enables Java to enter the field of small devices more effectively) the multi-language implementation capability through invokeDynamic and the productivity of Java itself through ProjectCoin.

Immediately after the article-pagination technology principle and implementation of the meaning and method of pagination (i), this article continues to analyze paging technology. The last chapter is about the simple principle and introduction of paging technology, this article in-depth analysis of the paging Technology Code implementation. The last chapter describes the best implementation of pagination is paging in the database layer, and different databases have different paging implementatio
