I forgot my OC4J administrator password.  How can I manually reset the password?

ANSWER:

• Open ${ORACLE_HOME}/j2ee/home/config/system-jazn-data.xml with a text editor.
  Find the <user> tag block for oc4jadmin. Change the oc4jadmin's <credentials> property to (substituting your password for myNewPassowd): <credentials>!myNewPassword</credentials>
  Be sure to preface the password with an ! to inidcate that this is a plain text value.
  When completed, the oc4jadmin <user> should look something like:

  <user>
      <name>oc4jadmin</name>
      <display-name>OC4J Administrator</display-name>
      <guid>E33D5A508AA511DF8F573778FB23EDF8</guid>
      <description>OC4J Administrator</description>
      <credentials>!myNewPassword</credentials>
  </user>
  

  Save the changes and restart the OC4J server.

I'm getting an oracle.xml.parser.schema.XSDException when I try to deploy my web application.

QUESTION:

• My laptop was formatted recently, so I installed MyEclipse 10.7.  When I tried to deploy my web application to my local OC4J server, I get the following error.:

  Deploy error: Deploy error: Operation failed with error:
  Line 10 in XML document from URL [code-source:/C:/oc4j_101350/j2ee/home/applications/dfp/dfp/WEB-INF/lib/csf-webservices-1.0.17-20130103.040738-23.jar!/applicationContext-csf-webservices.xml] is invalid; 
  nested exception is oracle.xml.parser.schema.XSDException: Duplicated definition for: 'identifiedType'
  

  I think it’s related to some XML parsers.  I don't think its MyEclipse that is causing the problem.

ANSWER:

• verify your OC4J configuration, particularly the swapping out of the Oracle XML parser.  Instructions on how to configure an new XML parser is described in Configure the OC4J stand alone server, section 4.
