코드양도 많이 줄일수 있고 뭐 간단하게 이것저것 테스트 하는 프로그램 같은거 만들기 쉽게 되어있습니다.
디자인이나 패턴쪽만 신경 많이 썼지..뭐..직접 코딩하는거 손 놓은지가 하도 오래되서...에궁...
가끔은 코딩에 푹 빠져보고 싶을때도 있자나요~~~ 뭐 접근하기 쉽고 배우기 쉬운 언어라서 틈날때마다
조금씩 해보고자 합니다.
Sun Microsystems makes every effort to ship each JRE update release with the most up-to-date Olson timezone data possible. Including current timezone data in each update of the JRE software, however, does not address earlier JRE releases that have already been installed and that are otherwise functioning adequately. The Java SE platform's timezone data is not read from the local or host operating system (OS), so OS timezone patches will not update the JRE software's timezone data. Consequently, older JRE releases might have outdated DST rules that have been superseded by changes in timezone boundaries or DST rules that are implemented after that release. As a result, applications running on an older JRE implementation in a region that has changed its DST rules might report the incorrect time after the date that the new DST rules were implemented. This can have serious consequences for software applications.
If you have installed the latest update release of the Java SE platform 6, or J2SE platform 5.0, 1.4.2 or 1.3.1, then you already have a recent version of the Olson timezone data. However, more recent Olson data that affects your timezone might have been released after the latest JRE update release. Consequently, if you are concerned about application failures that may result from any DST changes, you should perform the following steps:
Ideally, installing the latest JRE update release is the preferred vehicle for delivering both timezone data updates and other product improvements, such as security fixes. However, if the timezone rules in your region change and you are unable to use the latest JRE update release, then you will need to update the platform's timezone data without altering other system configurations and dependencies. If for any reason you cannot upgrade your JRE software to the most recent update release, you can use a tool that can modify the timezone data within your existing JRE software without requiring you to update the whole platform. This tool, TZUpdater, updates older installed JRE implementations with the most recent timezone data.
The TZUpdater tool works on version 1.4 and later of the JRE software and on all the platforms that are supported by Sun. The tool is designed and built to provide full compatibility with any existing, previously installed JRE software on your system. For details of the latest release of the TZUpdater tool, see the TZUpdater README.
Even if you do upgrade to the latest update release of the JRE software, it is still possible that the latest timezone data for your region is not included. In this case, you should run the TZUpdater tool. See Timezone Data Versions in the JRE Software to see which version of the Olson timezone data is included in which JRE update release.
On Windows, Linux, and the Solaris 9 and Solaris 10 operating systems, the J2SE 1.3.1 platform completed the Sun End of Life (EOL) process when the Java SE 6 platform was released on December 11, 2006. A paid Java Vintage Support Offering is available for those customers who are interested in continued support for the 1.3.1 release. Please contact your Sun sales representative for details. On the Solaris 8 operating system, the J2SE 1.3.1 platform will continue in the EOL process until the the end of its five year Vintage Support Period in 2009. During this EOL transition period, products continue to be supported on Solaris 8 per existing customer support agreements.
However, customers with support contracts running the J2SE 1.3.1 platform can download a version of TZUpdater for JDK/JRE version 1.3.1 from the SunSolve Support Solutions site.
Customers using older Java platform versions that have completed the Sun EOL process, such as the 1.1 and 1.2 release families, should upgrade to a release family that is currently supported in order to obtain the latest DST rules. EOL products are not supported under standard support contracts. A paid Java Vintage Support Offering is available for those customers who are interested in continued support for a specific EOL release. Please contact your Sun sales representative for details.

아마도 BEA 전반에 관련된 Admin 업무가 추가 될듯 합니다..에궁..
FYI, I have surveyed Weblogic Server version 10 including 10.3 that will be released on June-2008.
Please refer to followings. I have summarized new features. :)
If you need further information including high level cost estimation to upgrade, please let me know.
Weblogic Server 10
Simplified development
- Java EE5 specification implementation to improve developer's productivity.
- EJB 3.0 support for writing sophisticated enterprise applications and services
- JPA( java Persistence API) to simplify how developers map Java objects to relational databases and store these objects for later use
- Annotations for helping developers to reduce the repetitive, boilerplate code they must write.
- Support popular and useful opensource projects such as Spring Framework to write applications
- Providing Eclipse-based BEA Workshop for WebLogic platform integrated development environment (IDE).
New and improved Web services
- JAX-WS 2.0(Java API for XML Web Services) UPDATE based on GlassFish community project, providing solid implementation
- JAXB 2.0(Java API for XML Binding) UPDATE to simplify development of Web services by supporting important protocols such as SOAP and annotations
- JAX-RPC (equivalent JAX-WS 1.0) enhancement
- Interoperability enhancement for Windows
- New security-related Web services implementation as those standards have evolved
Operational efficiency in support of uptime
- Lock-and-edit feature to help prevent inadvertent errors
- Auto-record domain configuration changes to help cut down potential errors when working on repetitive procedures.
- High-availability functionality helps prevent downtime for users during failover across the network.
- Many automatic capabilities - ex) automatic transaction recovery service to ensure finalizing incomplete transactions in the server failure
- Diagnostic framework improvement during displaying diagnostic data
- Support important management standards such as SNMP v3
- Support prior APIs with offering automated domain upgrading via its domain configuration tool --> Easy upgrade from 8.1 to 10 :)
- Of course interoperable with previous releases including 8.1 that we are mostly using
Weblogic Server 10.3
Based on version 10, it enables more productive development environemnt.
