.cab to
.jar File Throws a Security Exception When Run in
Microsoft Virtual Machine (VM)After you upgrade a signed applet from .cab to
.jar files, the applet no longer works in the
Microsoft VM. The applet runs without any error in the Sun Java
Runtime Environment (JRE) implementation.
Microsoft VM does not support signed .jar files.
Microsoft VM supports unsigned .jar files through the
archive attribute of the <APPLET>
tag. However Microsoft VM treats classes and resources within the
signed .jar files as untrusted.
As a result, the applet is treated as untrusted by the Microsoft VM. Any action which the applet performs ,that requires access outside the applet sandbox, results in a security exception.
The only applet signing scheme recognized by the Microsoft VM is
Authenticode technology which is used with the .cab
files.
Specify the upgraded .jar files through the
archive attribute for the Sun JRE, and continue to
specify the .cab files through cabbase
for the Microsoft VM. For example, assume that you have the
following code:
<APPLET code="MyApplet" width=100 height=100>
<PARAM name="cabbase" value="package1.cab,
package2.cab">
</APPLET>
Change the above code as shown in the following code:
<APPLET code="MyApplet" archive="package1.jar,
package2.jar"
width=100 height=100>
<PARAM name="cabbase" value="package1.cab,
package2.cab">
</APPLET>
None.
