Class Loading PARENT_FIRST, PARENT_LAST explained

By default in IBM Websphere Application server the PARENT_FIRST option is selected for
class loading.

Classloadingdelegation Model.








As mentioned in the diagram

if delegation model is set to PARENT_FIRST it will try to load from the application jars which are present in WEB-INF/lib or WEB-INF/classes or  included in shared library references.

If the class expected is not present in the application loader it will look up to it parent until Bootstrap.

So in PARENT_FIRST the look up for classes is always upwards .If a class referenced by Ext loader is present in application level then that class will not be visible and throw exception.

PARENT_LAST is just opposite to PARENT_FIRST it  look for classes downwards  from root classloader.

Change sdk version in Websphere 8

Some software integrating with Websphere will require sdk 7 instead of default sdk 6 .There is
a  script available in profile bin directory to change the sdk version

Displays a list of all SDK names available to the product installation.
i.e. managesdk -listAvailable -verbose

-listEnabledProfile [-profileName profile_name]
Displays a list of all SDK names that specific profile is currently configured to use.
i.e. managesdk -listEnabledProfile -profileName default

-listEnabledProfileAll
Displays a list of all profiles in an installation and the SDK names that each profile is currently configured to use.
i.e. managesdk -listEnabledProfileAll

-enableProfile [-profileName profile_name] [-sdkname sdkName] [-enableServers] [-user user_name] [-password password_value]
Enables a profile to use a specified SDK name.
i.e. managesdk -enableProfile -profileName default -sdkname 1.6_64 -enableServers

-enableProfileAll [-sdkname sdkName] [-enableServers] [-user user_name] [-password password_value]
Enables all profiles in an installatino to use a specified SDK name.
i.e. managesdk -enableProfileAll -sdkname 1.6_64 -enableServers

-getNewProfileDefault
Displays the SDK name currently configured for all profiles created with the manageprofiles command.
i.e. managesdk -getNewProfileDefault

-setNewProfileDefault [-sdkname sdkName]
Changes the SDK name currently configured for all profiles created with the manageprofiles command.
i.e. managesdk -setNewProfileDefault -sdkname 1.6_64

-getCommandDefault
Displays the SDK name that script commands are enabled to use when no profile is specified by the command and when no profile is defaulted by the command.
i.e. managesdk -getCommandDefault

-setCommandDefault [-sdkname sdkName]
