Question

Plugin inside Sametime with Lotus Notes Classess - The Whole Story

Answer 1

+1 A:

Looks like CORBA classes are compiled for a newer JDK. You need to find an older version of the JAR, or, alternatively, get the sources and compile them under your JDK (J9?). From what I see from a brief Google search, J9 is either 1.4 or even 1.3 compatible.

Also, make sure that all the code you compile yourself has the same target Java version, i.e. 1.4 (1.3?) in this case.

A:

Well I was able to get my hands on jars that was there in LN 7 version. I put that into the project and this is what i got

The plugin itself is not loading because of the its not able to find NotesException class ?. Btw I am using 1.4 as the compiler version and I have j9 for running sametime. and 1.6 is the default jvm in my system.

NoClassDefFoundError means the class is not there OR it has some dependecies that not there or "broken" (e.g. compiled for a wrong JRE version). I only can tell that you have a severe case of versioning. I suggest you to find a known good plugin project, compile it and see if it's working. If it does, add classes slowly to it.

Vladimir Dyuzhev 2009-10-02 17:49:05

you were correct i get my hands on different version of notes.jar and created a plugin out of it and added that plugin as a dependency in the main plugin and got it work on the development environment. Now I am trying to deploy the same plugin which demands that i start a new post altogether. Thanks for the help :)

Answer 3

+1 A:

There are two jars that are related to talking to a Notes application.

Notes.jar - This is a JNI wrapper for LSXBE classes. In order for it to work correctly you will need Lotus Notes installed on the machine and the main directory on the system PATH.

NCSO.jar - This is for making DIIOP connections to a Domino server. This does not require Lotus Notes to be installed. It does require a Domino server you can connect to which has DIIOP enabled on it.

It is unclear if you have Notes installed?

The jars are also specific to certain JVM versions.

Java 6 - Notes 8.5.1
Java 5 - Notes 8.x
Java 1.4.2 - Notes 7.x
Java 1.3 - Notes 6.x

"bad major version at offset" means your are running the wrong jar for the JVM (eg. 851 jar on 1.4.2).

To rule out any configuration issues first I recommend creating just a simple java application which makes a connection to Notes/Domino. Once that works then you know your paths/jars are all set up correctly.

The error was definitely related to versions. I was using the Notes.jar on the ST J9 JVM which was causing this error. For that I used a Notes 7 jars files and created a plugin out of that and used that in J9 JVM which worked pretty well.
