Oracle SqlDeveloper/Jdeveloper extension

研究sqldeveloper的extension花了很多天的时间，这方面的文档不多，全靠jd反编译Oracle的class研究的。

Jdeveloper的扩展性设计的比较不错，可以灵活地对现有的产品进行扩展，研究过程中也学到不少东西。

只是Oracle的相关文档太少。

# How To Create a Java Defined Extension

https://wikis.oracle.com/display/oraclesqldeveloper/How+To+Create+a+Java+Defined+Extension

A SQL Developer extension consists of 5 main parts

    extension.xml which is the initial hook by which the extension is defined and loaded into SQL Developer.

    Extension Addin Java class, which provides additional hooks by which the extension is defined and loaded into SQL Developer programatically.

    Java classes which provided the extensions functionality

    XML files which provide a neater mechanism for extending certain parts of SQL Developer like the navigator

    Resource files like icon images

    Java extensions are deployed into jar files, which when placed in SQL Developers extension directory are loaded during SQL Developers next start up.
