ADF: Minor PS3 - PS5 bug

I could not access the security tab on my Webcenter admin console and was getting a  error which was cause by:

Caused by: java.lang.NullPointerException
    at oracle.webcenter.security.common.WCGroup.(WCGroup.java:74)
    at oracle.webcenter.security.common.IdentityWrapper.getGroup(IdentityWrapper.java:183)
 
We have a mapping from JNDI role to Administrator and it had this under members of the app role:
<member>
  <class>weblogic.security.principal.WLSGroupImpl</class>  <name>Administrators</name>
</member>

Removed this and all is good again.

ADF sort of generic screen for tables with the same structure

We have a couple (about a hundred) of tables with the same structure (Code, Description, Create Date, Update Date).

(the expression needs to change as I am reading web tier stuff from the model layer but I will fix this later) I then generated a java class for my EO. And added the following overriden method to my newly created java class. protected StringBuffer buildDMLStatement(int i, AttributeDefImpl[] attributeDefImpl,   AttributeDefImpl[] attributeDefImpl2, AttributeDefImpl[] attributeDefImpl3, boolean b) {   StringBuffer statement = super.buildDMLStatement(   i, attributeDefImpl, attributeDefImpl2, attributeDefImpl3, b); return new StringBuffer(StringUtils.replace(statement.to...

MANIFEST.MF merge JDeveloper for an executable jar

Goto your project > properties. Then click on deployment in the menu. Edit or add a jar deployment profile. Fill in the details under jar options (select Include manifest and give it a main class name) Also remember that the merge functionality only works with a BLANK line at the end of the merge file. REALLY this caught me. My merge file contents: Class-Path: commons-codec-1.3.jar [...empty line here CRLF...]
