Search for a specific class in a folder structure recursively

-
For those of you that have migrated java application from Fusion Middleware 11g to 12c, you will know that a lot has changed in the background. In my case, I was migrating a workspace application that heavily relied on Fusion Middleware/WebLogic libraries/classes. Some classes had changed packages or jars so changing the Maven dependency version to the current (12.2.1.3.0 in my case) was not enough. As you know, ORACLE_HOME contains hundreds if not thousand of jars, so I wrote a simple windows command to iterate in ORACLE_HOME folders, open all the jars that it encountered and search for the class name that you pass it. for /R %G in (*.jar) do @jar -tvf "%G" | find " WSSecurityContext " > NUL && echo %G

How to create a WebLogic DataSource using WLST and running it through Apache Maven

In this article, I will show you how to create a WebLogic DataSource. You will need two files to do this. In my case, I named them: createDatasource.properties createDatasource.py The properties file contains weblogic domain related information, while the python/wslt file contains the necessary WLST commands the create the datasource. Finally, to execute the script through Maven run: mvn com.oracle.weblogic:weblogic-maven-plugin:wlst-client -DfileName=createDatasource.py Alternatively, you can run the script through wlst.sh in your domain home: $ORACLE_HOME/oracle_common/common/bin/wlst.sh createDatasource.py The full code is committed here .

Transactions in Oracle SOA Suite 12c

-
Transaction Semantics Oracle SOA Suite uses the underlying Java Transaction API (JTA) infrastructure to handle its transactions. Oracle BPEL process manager creates a new transaction on a request basis. If a transaction exists, then it is suspended, otherwise it is created. In order to configure the transaction behaviour for a BPEL process, you must set a property named " bpel.config.transaction " in the component section of the composite.xml with one of the following values: required (default value) requiresNew notSupported For example: <component name="LocationHandlerProcess" version="2.0">     <implementation.bpel src="BPEL/LocationHandlerProcess.bpel"/>     <property name="bpel.config.transaction" type="xs:string"many="false">required | requiresNew | notSupported</property> </component> Synchronous invocations When the bpel.config.transaction is set to required ...

In this article, I will show you how to install ApacheDS on Linux and Apache Directory Studio on MacOS. At the moment, you cannot install ApacheDS using the default installer on Mac OS X High Sierra, since the installer tries to access folders that it not permitted by the OS. Therefore, I have installed ApacheDS on a Oracle Enterprise Linux VM running on VirtualBox and an Apache Directory Studio running on Mac. Section 1 - Install and start ApacheDS on Linux In order to install ApacheDS on Linux, follow the next steps: Download ApacheDS from here Open a terminal and navigate to your downloads folder chmod a+x apacheds-2.0.0-M24-64bit.bin   ./apacheds-2.0.0-M24-64bit.bin                                                                       To start ApacheDS run the following command "sudo /etc...
