No JRE version found in launch file for this system

Question

Hi,
I have an application which is launched by JWS.
When we use JWS from 1.4, it runs fine. But JWS from 1.5.0_15 gives the error "No JRE version found in launch file for this system"
In both the JWS(1.4 and 1.5.0_15)cases, we install JRE1.5.0_15 using the installer and used for invoking the application.
We invoke mailclient.jnlp, which inturn invokes the installer.jnlp and KanaJreInstaller.asp

We are using sun JRE(1.5.0_15) only. We extract Sun JRE and build it as KANAJRE.jar and signing.>I have never heard of KANAJRE. Would you care to post a link to the site, or should we just keep guessing? (My patience for random guesses is running out.)

We install using Intaller class and that is getting listed in the Java Control panel and enabled too.>List as what?
Does it list it with the entire string "KANA1.5.0_15" or is is just listed as "1.5.0_15"?
Because this line from the JNLP file..
<j2se version="KANA1.5.0_15" href="KanaJreInstaller.asp"/>..had me convinved it was a non-Sun JRE. Not so much the href, but most especially the version attribute.
If it really is the Sun JRE, I would expect this to work.
<j2se version="1.5.0_15" href="KanaJreInstaller.asp"/>And as an aside. If this installer is giving you trouble and the app. requires the 1.5.0_15 JRE, why not simply the default Sun JRE installer? What advantages do you think this installer offers?
