User getting an error message about being

User getting a message

HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Plug-in\1.3.1_01 is not found or is
no longer valid"
Cause
Resolving The Problem
These are the steps which helps to correct any general plugin issues.
1> Ensure that you have installed the correct plug-in which is
specified by Yantra. [look in the installation guide] , If there are no issues
when launching Yantra this is all set.
For Yantra 7.3 the valid plugin
would be 1.3.1_09
For Yantra 7.5 the valid plugin would be 1.4.2_03 (We
know problems where Config did not launch with 1.4.2_11)
2> If you have
problems where the system repeatedly tries to download the plugin, refer to
Solution 14600
If you do not have access to the Internet, and you have
the plugin downloaded to a local intranet/WAN directory set the yfs.proprrties
entry correctly
#yfs.config.java.plugin.codebase=
3> If you have
successfully downloaded and installed the Plugin, but you are still having
conflicts, and not able to launch the console/configurator. then this could be
a problem caused by an entry in your Windows PATH variable, which points to a
jre directory that is an earlier version. (In particular, if you install oracle
client software, chances are you will have the jre installed under the oracle
directory in the PATH variable).
Correct the PATH variable as outlined in
the example below.
Example to resolve the Issue with the System paths
when the system picksup a wrong JRE
FIXES to
Path
=============
Delete those paths containing the word
"jre".
Original
path
C:\oracle\ora92\jre\1.4.2\bin\client;C:\oracle\ora92\jre\1.4.2\bin;C:\or
acle\ora92\bin;C:\Program Files\Oracle\jre\1.3.1\bin;C:\Program
Files\Oracle\jre\1.1.8\bin;C:\PROGRAM
FILES\THINKPAD\UTILITIES;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System3
2\Wbem;C:\Program Files\ATI Technologies\ATI Control
Panel;C:\WINDOWS\Downloaded Program
Files;%SystemDrive%\IBMTOOLS\Python22;C:\Yantra\Yantra7x\bin
New
path
C:\oracle\ora92\bin;C:\PROGRAM
FILES\THINKPAD\UTILITIES;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System3
2\Wbem;C:\Program Files\ATI Technologies\ATI Control
Panel;C:\WINDOWS\Downloaded Program
Files;%SystemDrive%\IBMTOOLS\Python22;C:\Yantra\Yantra7x\bin
4> If
this still did not solve the problem, It is recommended you clean up all the
JRE by un-installing them and restarting the system, if required. Verify that
the windows registry is cleaned up, open the registry by regedit and Look for
any entries of JRE and delete them via Windows Control Panel. [User should
never attempt the regedit since modifications without knowledge of registries
keys could make the system unusable].
Note : You are also
recommended to uninstall the JRE only by Add/Remove Programs from the control
panel , but not by deleting the installation directory directly.
Also ensure in that SYSTEM PATH that you have the java/jre
path entry at the start of the SYSTEM PATH
5> If none of this
helps, As a last resort, you can edit the registry and make the following
changes. Please note this needs to be done ONLY by a superuser who is familiar
with registry modifications.
Sample Reg edit
FIXES to Registry [
version of JRE to use is dependent on the yantra version you are installing -
refer yantra installation guide]
=============
1. Run 'regedit' from
command prompt
2. Under HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java
Plug-in\
3. Create 1.3.1_01 as key
4. Under 1.3.1_01 create New-> Binary
Value as JavaHome
5. Modify and give value as C:\Program
Files\JavaSoft\JRE\1.3.1_09
