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

are you specifying the required classid in your html?

Thats using the dynamic classsid.

j74

ASKER

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

Mick Barry

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.

Mick Barry

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

j74

ASKER

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

j74

ASKER

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.

Mick Barry

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.

j74

ASKER

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.

j74

ASKER

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)

Mick Barry

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

j74

ASKER

what is dynamic clsid? can we have different clsid. It does not look working if we change the clsid.any other opinion plx to overcome this issue

Mick Barry

> what is dynamic clsid?

it is what u are using, it says use *any* version of the plugin.

> can we have different clsid.

yes each version has its own classid

j74

ASKER

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.
