How to install OC4J instance

Hello,

In this post I'll take about how to install an OC4J instance.

Go to Oracle Website, and download JDeveloper (I am using jdevstudio10134.zip)

unzip the jdevstudio10134.zip in any directory of your choice...
Then edit this file: jdevstudio10134/j2ee/home/config/system-jazn-data.xml

Found the following block in the above file:

<user deactivated="true">
    <name>oc4jadmin</name>
    <display-name>OC4J Administrator</display-name>
    <guid>EB5375602AD911E08F414FF4AB83D954</guid>
    <description>OC4J Administrator</description>
    <credentials>{903}74I5jSo1O543z7HPDrz+wJO78gtkQ+IK</credentials>
</user>

Change the following:

<user deactivated="true">

To be:

<user deactivated="false">

The default password is "welcome" without double quotes.

Oracle Application Server overrides your own Jars

Hello,

I've noted that, Oracle Application server overrides Jar files that found on the app server.

You will need to customize your classpath when deployin from the `em` to make it works for you.
