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.  The config details are described here: <https://wikis-mit-edu.ezproxyberklee.flo.org/confluence/x/zNnzB | parser configuration> and the XML parser config is in section 4 of that page.
