Troubleshooting Mouse Focus Issues Using JRE Clients with EBS 11i

I'm pleased to hear that many of you are heeding our urgent call to retire JInitiator for the native Sun JRE plug-in.  Thanks for your emails and comments about your experiences; these have been very useful in helping us understand the types of stumbling blocks that you've been encountering along the way.

Some of you may have encountered issues with mouse navigation in Forms.  Others have reported intermittent focus-related issues, which may be compounded by mouse navigation issues.

It appears that the majority of these issues may be related to your Forms 6i patchset level installed in your E-Business Suite Release 11i environment.  That said, there may be other configuration-related issues in your environment that are complicating things further.

Our Support team has put together a useful Note that walks through a diagnostic process for isolating and fixing these issues:

Naturally, we're very interested in helping you get through this upgrade process with a minimum of pain.  If you hit any problems with your conversion to the native Sun JRE plug-in, please log a formal Service Request via Metalink.  Our Support engineers will work with you on this, and also track the underlying issues to see whether changes to our documentation or patches are warranted.  If necessary, we'll work with Sun to get fixes prioritized for future JRE releases, too.

Which JRE Versions Are Certified With Which Browsers?

This depends on your Windows operating version and the browser that your firm has deployed. Various combinations of Windows XP, Windows Vista, Microsoft Internet Explorer (IE) 6 and 7, and Firefox are now certified with JRE 1.5 and 1.6. To review the new minimum certification levels, see:

Hi Steven,

I just wanted to let you know that the company I work for is one of the customers that uptook the October CPU patches, which required Developer 6i Patchset 19 as a prerequisite.

We are running JRE 1.5 and are primarily having Problems 2 & 3 listed in Note 760250.1. Upgrading to JRE 1.6 is not something we can do very quickly, so I hope Patch 7647672 is released soon.

Thanks for everything your team does. I subscribe to your RSS feed and enjoy your posts.

Thanks,
Shad

Hi Steven,

I think the problems listed in this document should be amended to include the bug below:

7485019 SUN JRE 1.6.0_10 RC2 : RESIZING THE FORMS APPLET WINDOW HANGS THE FORMS SESSION

It would also be helpful to others if a link to this document or a reference to this document were included in the Note 125767.1 - Upgrading Developer 6i with Oracle Applications 11i in the known issues section.

Also I am still working with support on the forms freeze when using the mouse to copy and paste - SR 7366849.992 that occurs with PS19 and 1.6.0_11.

Thanks, Dawna.

Hi, Shad,

Thanks for the feedback on our blog.

Thanks for letting me know about the issues you've encountered. I've passed your comments on to our team that's working on bug 7647672. I'll post an update here as soon as there's good news to share on this front.

Regards,
Steven

Hi, Dawna,

Thanks for the suggestion. I'll make sure that our documentation reflects this known issue while we're pursuing this bug. It's likely that we'll end up putting this in Note 290807.1 rather than the Dev6i Note.

Regards,
Steven

Hi Steven,
How does this technology stack change impact the DR App servers? Is that the manual script needs to be re-done after the autoconfig DR step in case of a DR test?

Posted by Praj on February 10, 2009 at 03:53 AM PST #

Hi, Praj,

I'm assuming that DR in this case refers to a disaster recovery active-passive configuration that you'd like to failover to.

Your DR environment should be configured to use the same JRE as your production environment. If that's the case, then the end-user's installed JRE version will continue to work on the DR instance in the same way that it works on the production instance, with no additional desktop or mid-tier reconfiguration required -- for the JRE component, at least.

Regards,
Steven

Hi Steve,

I desparately need some help in my E-biz R12 install. I recently completed R12.0.4 installation and started up all the services. I logged into the environment frommy pc, the login works and I can see the menu. When I try to drill down more and try to open forms, the form does not launch and this is what I see in java console:

Following Exception occured: java.lang.IllegalArgumentException: Illegal argument for colorScheme applet parameter
java.lang.IllegalArgumentException: Illegal argument for colorScheme applet parameter
at oracle.forms.engine.Main.initDesktop(Unknown Source)
at oracle.forms.engine.Main.start(Unknown Source)
at sun.applet.AppletPanel.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)

My pc OS is windows xp professional version 2002 service pack 2 and IE version is IE 6.0.29

I know there is nothing wrong with the R12 install the forms work for some users and do not work for some users. Not sure what am I missing on my pc. Any suggestion on this issue will be really helpful.

Thanks

Rashmi

Hi, Rashmi,

I'm afraid that I don't have enough experience with Windows-based installations to provide any meaningful advice for this. I'd recommend logging a formal Service Request via Metalink to get one of our Support Engineers engaged.

Regards,
Steven

Hi Rashmi,

Is your problem solved?
