Java Plugin 1.3.1.x and 1.4.2.x coexistence issue

Our customer has application where there is must of  JRE 1.3.1.x plugin is needed. But we gave him application which must require JRE 1.4.2.x.
Customer's browser's default JRE is getting overwrriten.
We followed following approache to resolve
1) install JRE1.3.1.x and make that as default JRE
2) Now for JRE1.4.2.x, we told cutomer to go for custom installation so that he should be not selecting this JRE1.4.2.x as default.
Even though customer's system has defined the JRE version in his html for his application, but the jer1.4.2.x is getting used when he tries to acces his application after JRE 1.4.2.x comes and sit in the machine.
Customer wants both co-exist. This looks near not to possible. Is there any way to handle this issue and make my customer happy?
thanks~Veerendra

When I stall 1.3.1.x as last, that customer application works. But when he tries my application again he will be prompted to install 1.4.2.x even though he has already installed it.
I am finding the same as mentioned above texts

objectsCommented:
classid for 1.3.1 specifically is:
CAFEEFAC-0013-0001-0000-ABCDEFFEDCBA
but it's also different for each 'sub' version.

can u explain again exactly what is is you need used.

objectsCommented:
do you know if your customers html ends up using the object or the applet tag?

j74Author Commented:
I got the class id from html converter tool which comes with jdk.

j74Author Commented:
Customer is not ready to change his app becuase it is coming as end of life by this year and on top it his application is developed by third party so no supprt on that app. So basically our applet/ way of installing plugin should take care of.
0
 
objectsCommented:
you could try using the following classid fin your html:

CAFEEFAC-0014-0002-0000-ABCDEFFEDCBA

asking for 1.4.2 or later.

its strange that your html prompts for install and theres doesn't considering they both use the same classid. Unless the customers is using the applet tag and thus the default vm.

j74Author Commented:
yeah. I agree. If the customer was using applet tag we could have told him to install JRE 1.3 and make that as default. Then it would be have worked both app.

j74Author Commented:
I don't know why SUN is giving same classId for JRE 1.3.1.x and JRE 1.4.2.x (i.e. 8AD9C840-044E-11D1-B3E9-00805F499D93)

objectsCommented:
thats the dynamic classid, stating to use the default vm.

j74Author Commented:

objectsCommented:
> what is dynamic clsid?

> can we have different clsid.

yes each version has its own classid

j74Author Commented:
I gave CAFEEFAC-0014-0002-0004-ABCDEFFEDCBA which in jinstall-1_4-windows-i586.cab file. We changed the dynamic clsid with this one. Now we get the blank page. Nothing seems working.
