Solution for Fetch serialized object failed error in JDE Web Client

Scenario

While running jde web client on your local machine : http://localhost:8080/jde/E1Menu.maf

Applications fail to open and an error prompt occurs saying

COULD NOT LOAD FORM : APPCODE_XXX_XXX

JAS_MSG431 : Fetch serialized object failed. Please contact your system administrator.

Solution

You need to comment out the [JDBj – SPEC DATA SOURCE] in your jdbj.ini file.

jdbj.ini file location as per Oracle documentation :

For OH4A, the jdbj.ini file is located in this directory on the Development Client machine:

<installpath>\system\OC4J\j2ee\home\applications\webclient.ear\webclient\WEB-INF\classes\jdbj.ini

For H4A7 and H4A85, the jdbj.ini is located in this directory on the client machine:

<installpath>\JAS\EA_JAS_80.ear\webclient.war\WEB-INF\jdbj.ini

In my case it was located on my client machine at :

E:\E_910\system\OC4J\j2ee\home\applications\webclient.ear\webclient\WEB-INF\classes\jdbj.ini

Open the file, scroll below to find the [JDBj – SPEC DATA SOURCE] section. Comment (by placing # in front of each line) all the following lines “in [JDBj – SPEC DATA SOURCE] section only”.

Logout and Login again to verify if the changes made resolved the error or not.

It worked for me.
