Troubleshooting EBS Java Applet Launch Error


Java applet launching issues occur in large numbers for those users who have a 64 bit OS and are accessing the application through a VPN tunnel. While those who have 32 bit OS are less prone to face this issue regardless they are accessing through VPN tunnel or not.


Introduction: 

The EBS Java Applet error is one of the most frequently encountered issues that every Oracle EBS user faces, while launching the regular apps form built-in Java applets. In this blog I will discuss the possible causes of this problem and the most feasible steps to troubleshoot them.

To begin with, I would like to point out that applet launching issue occurs in large numbers for those users who have a 64 bit OS and are accessing the application through a VPN tunnel. While those who have 32 bit OS are less prone to face this issue regardless they are accessing through VPN tunnel or not.

Let’s discuss the steps to fix this issue:

  • In case an application is being accessed through VPN, make sure user has all the rights related to the VPN tunnel.
  • Uninstall every version of Java/JRE from the user’s machine.
  • Download Java 7.0.51 b 32bit, however note that JRE should be 32 bit despite your system running on a 64 bit OS.
  • Install a new Java 1.7.0.51 using “Run as administrator”.
  • Take an additional step and go to the C: drive where Java is installed and make sure that you have given full control to Java directory. Refer to the snapshot below.

    Now set the parameter for JRE as per the screenshot given below:

    A)oracle ebs support


B)
manage java runtime versions

c) Add string   -DJava.vendor="Sun Microsystems Inc."  to the Runtime Parameters.

  • Firefox Mozilla is the recommended browser to access the application’s applets. Make sure that you have installed Firefox Mozilla Setup 35.0.1 but not above, there are very high chances that later versions of Mozilla will leave your problem unresolved.

    There is a caveat, despite following above steps there is a probability that when you try to open an applet form, it may take longer to open and eventually an error message as shown below:

    The above error is not so frequent, however a few users may experience it. In order to resolve this error, the user may need to switch to JRE 1.6.0_37 as shown below:


    java control panel support


    A user needs to execute all steps 1 to 7 as discussed above for JRE 1.6.0_37 too, this version will fix your trouble with   

    oracle.apps.fnd.formsClient.FormsLauncher.class not found exception.

    Conclusion:                 

    The above steps will fix the EBS Java Applet error for most users.  It will allow the user to open the applet forms for both the EBS 11i and R12 version without compelling a user to install multiple versions of JRE in the system. For any questions feel free to reach out to me.
