Bored of the same old Jdeveloper splash


If you get bored with the same old splash screen for jdeveloper, then go straightaway and modify the file from

${JDEV_HOME}/jdev/bin/splash.gif

Do not change the dimension. Look at mine  🙂

Keep playing…

I was wondering where the system folder in windows resides. searched all the place and stopped until i got this

C:\Documents and Settings\{user_id}\Application Data\JDeveloper


Quick look at the mediator component


What is Oracle Mediator Component?

Mediator is the load balancer which can route, filter, validate and transform data from the service providers to external references

  • Route: determines the service component to which the message has to be sent
  • Validate: validate the incoming payload information
  • Filter: Filters the payload for specific information before routing it to the specific component
  • Transformation: Transforms data from one xsd format to another using XSL Mapper

the code specific to mediator in the composite.xml will be like

<component name="ConversionMediator">
<implementation.mediator src="ConversionMediator.mplan"/>
</component>

Mediator component in the design view consist of

Name: Name of the mediator component

WSDL Url: the service provider URL

Port Type: The port on which the request message is sent

Resequence Level: Whether the sequencing of the incoming message will be taken care commonly[Operation] or for each component [component]

Priority: priority set for parallel routing rule

validate XSD: validate the schema for the incoming message

Callouts: specifies java classes for extra logic in programmatic way

Resequence:

Standard -> the incoming message will be sequence based on the sequence id

Best Effort -> sequencing based on the best possible way

FIFO ->  sequencing of message based on the time of the arrival of the message

Static Routing:

routing rule based on static information

Filter -> content based or header based routing

Transform -> using xsl mapper file

validate -> using schematron file

Assign -> assign header,payload values of the message from source to target

sequential -> rule executed one after the other

Parallel -> rule executed in parallel. Priorities are given to the parallel rule

Dynamic Routing:

routing rule based on external rule which keeps changing based on the invocation context

Fault Handling: This is handled in composite or at the component[mediator] level by specifying fault policies

Event Handling: A mediator can subscribe or publish an event

SOA Extension for JDeveloper

You can install the extensions directly from inside JDeveloper through the “Help -> Check for Updates” menu option which is the recommended way install extensions. If you can’t connect to the Internet from your JDeveloper, you can directly download JDeveloper extensions from this page, and point the Check for Updates wizard to the local file you have downloaded.

BINDING.JCA-12563 resolution


If you ever face issues like

BINDING.JCA-12563 Exception occurred when binding was invoked. Exception occurred during invocation of JCA binding: “JCA Binding execute of Reference operation ‘Write’ failed due to: Input Source null. Input Source null. Input Source is null. “. The invoked JCA adapter raised a resource exception. Please examine the above error message carefully to determine a resolution.
then there is a problem in the xml transformation in the mediator to write the file
Resolution:
Look if the transformation information in the mediator is proper.
Check if the transformation exist in the first place.

How to by pass some restricted access in Windows


Ever wonder how to get access to restricted application or options in windows.

Here in this post I am going to explain the utility provided by microsoft for administrators to enforce restrictions easily.

the utility is called  ‘gpedit.msc‘ means Group Policy Editor

what is Group Policy Editor?

The Group Policy Editor console is a graphical user interface(GUI) which allows admin to edit registry entries easily.Manually editing  registry entries is advisable and sometimes it will cause some unexpected problems.The gpedit.msc tool makes the administration of registry easier

There is another utility called ‘secpol.msc‘ which is similar to group policy which is used to edit subgroups

How to run Group Policy?

go to run  and type ‘gpedit.msc

Where all the information’s are stored?

All the information that is edited from group policy editor will affect registry editor directly.

The physical location of the modified files will resides in

%SystemRoot%\System32\GroupPolicy\

There are three folders to store information related to Admin, Machine and User related configurations

The Adm folder contains all the entries enforced on the system by the administrator and these entries directly maps to the windows registry

For example if you want to disable connection tab from internet Explorer you locate

Administrative Templates – Windows Component -> Internet Explorer -> Internet Control Panel

Click on ‘Disable the Connection page

Click ‘Enable’ and then press ok.

Now if you open Internet Explorer you will not see the connection tab in the Internet options page from Tools menu

The above mentioned is a simple example of how and why group policy is used. You can explore more options yourself to enforce/restrict user access

To more on the options Group Policy Settings download the respective excel spreadsheet for your windows operating system
