ADF Custom declarative component error 11.1.2

OK so I though the components where broken in 11.1.2 but it turns out it was just me who was broken.

Here a a couple of things I struggled with:

Naming yes I got the name of my custom component in declarativecomp-metadata.xml component file I had an extra l in my taglib-name. (if you get a blank page like me check the spelling then check it again)

I also put the folloing in my consuming project - dont know if it is necessary but it made me feel good:


<context-param>
  <param-name>javax.faces.FACELETS_VIEW_MAPPINGS
  <param-value>*.jsf;*.xhtml
<context-param>
<context-param>
  <param-name>javax.faces.FACELETS_SKIP_XML_INSTRUCTIONS
  <param-value>true
<context-param>
<context-param>
  <param-name>javax.faces.FACELETS_SKIP_COMMENTS
  <param-value>true
<context-param>
<context-param>
  <param-name>javax.faces.FACELETS_DECORATORS
  <param-value>oracle.adfinternal.view.faces.facelets.rich.AdfTagDecorator
<context-param>
<context-param>
  <param-name>javax.faces.FACELETS_RESOURCE_RESOLVER
  <param-value>oracle.adfinternal.view.faces.facelets.rich.AdfFaceletsResourceResolver
<context-param>


Also small tip for those who live in history the tab lib is Faclets Tag Libraries not JSP Tag Libraries this may save you a few seconds.

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). So I wanted to do something simple so that I did not have to create all these screens 1) EO   I created the EO based on one of the tables I had that had the above columns. I then Added a transient attribute called table name to my EO based on a groovy expression. (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...]

ADF: LOV Description instead of code

I keep on forgetting how to do this so this is a note to self in terms I understand (ie pictures): Add the related entiy object to yours (in the example we are adding RegionEO(list of values) to CountryEO) Now add the RegionName field from the EO and a transient attribute (I named mine RegionNameLOV) Make the transient attribute updateable and base it on the expression RegionName (the description you wish to display) Add a list of values to RegionNameLOV and map BOTH key to parent fk (region id here) AND RegionName to your transient coulmn (RegionNameLOV).  Map the transient as an Input text with List of Values. Then just drag the lov item onto the page (RegionNameLOV)
