ADF: the oci driver

Ok so we had a requirement to check if the oci driver would work with ADF. So here are the steps I followed to get it working quite simple I think. Will post here if there are any problems with using the driver but with a quick scan test everything looks ok.

1) Installed the oracle client on our weblogic box.
2) Replaced the ojdbcdms.jar reference in the weblogic classpath with the exact version that comes with the client (VERY important)
3) changed my connection string to jdbc:oracle:oci:@127.0.0.1:1521:SID.


Things that will be investigated : Client side caching, speed tests, amount of connections


Notes: UnsatisfiedLinkError - ocijdbc11.dll not found
Change your path on your system to have your client library location as the first in the list - ie for me I installed my client to C:\Oracle\11.2.0\client64 so that dir must be the first entry in my path.


java.lang.UnsatisfiedLinkError: oracle.jdbc.driver.T2CConnection.getLibraryVersionNumber()IYou are using the incorrect version of the ojdbc driver make sure you are using the one that came with the client and it is the first driver weblogic loads.

Shortcut to test :
Rename this file to  ojdbc6dms.back
[your middleware install location]oracle_common\modules\oracle.jdbc_11.1.1\ojdbc6dms.jar

Copy your ojdbc6dms.jar from your client (or download from Oracle)  to the above location. Restart weblogic.

    Hi Donovan,

    Do you have any idea what could be the problem if I'm getting this error:
    java.lang.UnsatisfiedLinkError: orageneric10 (Not found in java.library.path)

    This is happening when I'm executing the below code:
    String temp = oracle.xdb.XMLType.createXML((OPAQUE)rs.getObject(1));

    Also, I downloaded INSTANT CLIENT, could that be the problem?

      Hi,

      Any UnsatisfiedLinkError mostly have to do with dll/so files not being on the path. (I assume you are running on windows - linux is a bit different let me know if you are running linux)

      I have the full client installed (on my forms installation) and my dll is in the C:\DevSuiteHome\BIN directory.

      I dont know much about the INSTANT CLIENT but step one would be to do a search on your drive for orageneric10.dll and pop that directory on the PATH (Enviroment variable). If you dont have the dll try the full client.

      Hope this helps.

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...]

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...

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.
