Hi Team,

We have custom created and added Object Type Called LargeObjectType in model. It has writeText method which I want to override on the server side such that when writeText method is called from UAExpert client, the call goes to override method. I have read below solution in forum:
https://forum.prosysopc.com/forum/opc-ua-java-sdk/overriding-filedirectorytype-methods-and-massspectrometerdevicetype-methods/

“We do have an alternative way to make method impls for these cases. For the server side, the codegen creates for each UA Method in the model an interface TypeNameMethodNameMethod, for this case e.g. FileDirectoryTypeCreateFileMethod. Its parameters include the “FileDirectoryTypeNode node”. Create an implementation of this interface and call the static method FileDirectoryTypeNodeBase.setCreateFileMethodImplementation(instance_of_your_impl_here). SDK will then call that for you whenever the method is called (note that then the equivalent method in the XXXTypeNode is not called). Additionally, since statics can be seen via subtypes in java, I might call this via FileDirectoryTypeNode instead of the XXXNodeBase, but either works.”

I have implemented below solution but the call doesn’t reach the overriding method. Kindly help if I am doing something wrong here:
public class testClass implements LargeObjectTypeWriteTextMethod {
@Override
public LargeObjectType.WriteTextMethodOutputs writeText(ServiceContext serviceContext, LargeObjectTypeNode node, UnsignedLong position, String content, UnsignedInteger version, LargeObjectWriteModeEnum writeMode, Boolean markIncomplete) throws StatusException {
LargeObjectTypeWriteTextMethod abc = new LargeObjectTypeWriteTextMethod() {
@Override
public LargeObjectType.WriteTextMethodOutputs writeText(ServiceContext serviceContext, LargeObjectTypeNode node, UnsignedLong position, String content, UnsignedInteger version, LargeObjectWriteModeEnum writeMode, Boolean markIncomplete) throws StatusException {
return null;
}
};
LargeObjectTypeNodeBase.setWriteTextMethodImplementation(abc);
return null;
}
}

Thanks
