Jdev Extension Jar put in a directory other than "JDEV_HOME/jdev/extensions

Question

I'm creating new rules for auditing using the Jdeveloper 10.1.3 extension API and enabling using extension framework. Once I created the rule, I placed the 'jar' file in "JDEV_HOME/jdev/extensions/" directory as per the guidelines. It is executing perfectly. But I want to place the jar in my home directory. is it possible?
I mean I place the jar file in my home directory and I will provide classpath in 'extension.xml' file, which is a part of jar file. How can I achieve it?
The 'jar' file contains
a) extension.xml
b) 2 java files
c) one text file.
Here extension.xml mention the link of a rule to the audit framework. I used the
A part of extension.xml file which adds my rule to the framework.
<hooks>
<jdeveloper-hook xmlns="http://xmlns.oracle.com/jdeveloper/1013/extension">
<addins>
<addin>oracle.test.launcher</addin>
</addins>
</jdeveloper-hook>
</hooks>
I heard that we can do this in different types:
a) In <hooks> tag, we can include the <libraries> tag which mentions the classpath tag and value.
But no where I found the <libraries> tag in google search.
b) In "JDEV_HOME/jdev/extensions/" directory we place a jar file which only contains the 'extension.xml' file and we can specify the class path of the jar file, which contains the remaining three files. is it possible? If so pls. show me the pointers to do this.
Could you pls. suggest me.
Thanks in Advance

Hi,
You can install extension jars in your jdevhome extensions directory in addition to the standard OH/jdev/extensions. On platforms other than Windows, this is ~/jdevhome/extensions by default. On Windows and other platforms, the location of the jdevhome directory can be controlled using the environment variable JDEV_USER_DIR.
Adding an extension jar to one of those two locations is usually sufficient to add it to the classpath of JDeveloper. If you have additional non-extension jars you want to add to JDeveloper's classpath, you can do so using the <classpaths> element in extension manifest. This contains <classpath> elements which are relative paths to jars from the location of the extension jar. For example, say you have
~/jdevhome/extensions/my.extension.10.1.3.jar
and you want to include
~/jdevhome/someotherjar.jar
You would use something like this:
<extension ...>
  <classpaths>
    <classpath>../someotherjar.jar</classpath>
  </classpaths>
</extension>Thanks,
Brian
