Problems with corba initialisation due to migration from plug in 1.3 to 1.4

Question

Hi all.
We're attempting to debug an internet banking applet used by our company. This applet was written to run under JRE 1.3, however due to business requirements our company has upgraded to JRE 1.4. Under the 1.4 JRE, the applet no longer starts up cleanly, due to an exception that is thrown during CORBA initialisation :
org.omg.CORBA.INITIALIZE: org.omg.CORBA.INITIALIZE: Unable to create a ClientInterceptor because of:
java.security.NoSuchProviderException: JCE cannot authenticate the provider Cryptix 
vmcid: 0x0  minor code: 0  completed: No  vmcid: 0x0  minor code: 0  completed: No
     at com.visigenic.vbroker.orb.ORB.installServices(ORB.java:881)
     at com.visigenic.vbroker.orb.ORB.initialize(ORB.java:829)
     at com.visigenic.vbroker.orb.ORB.set_parameters(ORB.java:950)
     at org.omg.CORBA.ORB.init(Unknown Source)
     at za.co.sbic.main.LogonIIOP.run(LogonIIOP.java:88)
     at java.lang.Thread.run(Unknown Source)The Cryptix provider that the applet uses is an old unsigned version, and the Cryptix website appears to be unmaintained. To this end, we acquired a Java Code Signing certificate and signed the cryptix provider with our certificate (in order to render it usable in the 1.4 JCE). However, even with the signed jarfile, the above exception remains. I have tried moving the provider jarfile into /lib/ext, but I still get the same exception. Also, the development division of the bank that wrote the applet currently has no plans to port it to java 1.4
If anyone could suggest a reason for the above exception, or other avenues I could pursue, I would be grateful.
Thanks
Jeremy

Answer 1

U need to add this provider statically in <java_applet_home>/jre/lib/security/java.security file the following property
security.provider.n=cryptix.provider.Cryptix (n can be any number from 1 and in jdk1.4 there are already 5 providers, so n might be 6 unless u have add/deleted some providers.
To add a provider dynamically instead of static,
java.security.Security.addProvider(new cryptix.provider.Cryptix());
this piece of java code will help.
One more tip might help.which lib/ext directory did u put the jar file? if you are on windows, there is a possibilty of more than one jvms in ur system.
let me know if this works out r u need further help.
