A DESCRIPTION OF THE REQUEST :
Can not run in the same internet explorer two pages running a different JRE version (1.3.1_02 and 1.4.2_04 for instance)
If so a "register failk" message appears before a "Runtime error!" in IExplorer.
The same applies if first JRE 1.4.2 and then JRE 1.3.1.
The applet for 1.3.1_02 is run trhough OBJECT tag as :
<OBJECT classid="clsid:CAFEEFAC-0013-0001-0002-ABCDEFFEDCBA"
width="400" height="100" align="baseline"
codebase="">
<PARAM name="code" value="JavaVersionDisplayApplet">
<PARAM name="codebase" value=".">
<PARAM name="type" value="application/x-java-applet;jpi-version=1.3.1">
<PARAM name="scriptable" value="true">
This applet has been designed to work with java plug-in version 1.3.1
</OBJECT>
JUSTIFICATION :
1) to conform to the standards
2) to keep the ability for application that needs 1.3.1 (and that can not run 1.4.2) to run.
3) because MSJVM and JRE 1.4 works fine together so why JRE 1.3 and JRE 1.4 should not
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Have two pages one with a standard applet one with an applet running through OBJECT tag pointed to version 1.3.1
ACTUAL -
Can not run in the same internet explorer two pages running a different JRE version (1.3.1_02 and 1.4.2_04 for instance)
If so a "register failk" message appears before a "Runtime error!" in IExplorer.
The same applies if first JRE 1.4.2 and then JRE 1.3.1.
The applet for 1.3.1_02 is run trhough OBJECT tag as :
<OBJECT classid="clsid:CAFEEFAC-0013-0001-0002-ABCDEFFEDCBA"

<PARAM name="codebase" value=".">
<PARAM name="type" value="application/x-java-applet;jpi-version=1.3.1">
