oracle.adf.rc.exception.CatalogRuntimeException: error while obtaining a connection context using connection context provider [oracle.adfinternal.rc.connection.AdfConnectionContextProvider

 Got this exception when upgrading to 11.1.1.9: the connections.xml file in [your jdeve location]system11.1.1.9.40.66.73\o.jdevimpl.rescat2\connections was 0 bytes.

I copied it over from the old version and everything is working again.

I could not run my adf application while the connections.xml was empty.

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...]
