ADF programmatic disabled

I am creating dynamic links and here is something useful I used for programmatic creatin of the links.

uiCompnent.setValueExpression(
  "disabled",
  JSFUtils.getValueExpression(
    "#{bindings.MyVOIterator.estimatedRowCount == 0}",
      Boolean.class));

public static ValueExpression getValueExpression(
  String expression, Class clazz){
  FacesContext ctx = FacesContext.getCurrentInstance();
  ELContext elCtx = ctx.getELContext();
  Application app = ctx.getApplication();
  return app.getExpressionFactory().createValueExpression(
    elCtx, expression, clazz);
}

JBO-25013: TooManyObjectsException

oracle.jbo.TooManyObjectsException: JBO-25013: Too many objects match the primary key oracle.jbo.Key[Key null ].

ADF Encountered deferred syntax #{ in template text.

OracleJSP error: oracle.jsp.parse.JspParseException:  Error: Encountered deferred syntax #{ in template text.  If intended as a literal, escape it or set directive  deferredSyntaxAllowedAsLiteral This normally happens when you have some tag lib dependancy problems but this was  not the case for me... My problem: For some reason my model project had web stuff in it(public html etc)  so I had to remove the public html stuff from my project and manually edit the Model.jpr project file and remove the tag lib entries at the bottom o the file. Go figure.

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...]
