JDeveloper: JEE Web Application

I had to throw together a quick demo of the JDeveloper JEE functionality and was pleasantly surprised what Jdeveloper give you for free. Will be posting some of what I have found.

Create a New JEE Web Application and press OK button



Fill in your info here  replacing ProjectName with your project
Name: App
Package prefix: eg: za.co.test
Next * 5
Finish

Now on to creating an EJB Entity: Select Entities from Tables and click ok

As we are creating the first ejb in the app you can click next on the persistance unit screen.



I am going to select the  countries and regions tables from the HR schema by selecting them and clicking the blue arrow after querying all the tables. Next.



Next Select Discover foriegn keys dynamically.

Next * 3 but take note of the info in the screens. (You can change the class and package names etc)
Finish

Now take note of the java classes created complete with annotaions and relationships very nifty.
Also take a look at the persistence.xml file created in the META-INF dir.

You have created you first next on to a session bean to expose methods on these entities. Will post this soon.

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.

JBO-25013: TooManyObjectsException

oracle.jbo.TooManyObjectsException: JBO-25013: Too many objects match the primary key oracle.jbo.Key[Key null ]. Ok so for you it may be trying to insert a duplicate record this should explain your problem (also check trigger they could be the cause.) NOTE: You can also try to create a new duplicate EO if you have a page with two VO's using the same EO. This could sort your problems. For me I needed to add a launch listener on my LOV and clear the cache of my vo. LOV <af:inputListOfValues id="NameId" popupTitle="#{bindings.Name.hints.label}" value="#{bindings.RolName1.inputValue}" label="#{bindings.RolName1.hints.label}" model="#{bindings.RolName1.listOfValuesModel}" required="#{bindings.RolName1.hints.mandatory}" columns="#{bindings.RolName1.hints.displayWidth}" shortDesc="#{bindings.RolName1.hints.tooltip}" launchPopupListener="#{backingBeanScope.backingBean.launchPop

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...]
