Connector for StreamBase LiveView

The StreamBase LiveView connector allows connection to the StreamBase LiveView instance on a real-time streaming basis.

 

 

NOTE

When using StreamBase version 7.6 (and possibly some additional later versions), you will be affected by a bug inside the StreamBase dependency ICU4J.jar which is part of sbclient.jar. The bug is that the Java version must be less than 1.8.0_255. The bug will cause an error, showing in the Panopticon log as follows: “Invalid version number: Version number may be negative or greater than 255”. The bug in ICU4J.jar was fixed in version 68.1. StreamBase versions using ICU4J.jar version 68.1 or later will not have this bug.
