Question:
Where are you getting your documentation on including Extent Reports in TestComplete? Generally speaking, TestComplete can utilize JavaClasses and JAR files As-Is. There isn't anything explicit about TestComplete and Extent Reports so anything having to do with which classes, objects, properties, etc., is something that comes from Extent Reports so should be addressed on that end.
There is no specific documentation on how to integrate extent report with test complete. I am follwing the steps from extent report site mentioned for Java Project. These jaf files and Java classes are working fine for selenium java and VisualStuidi c# but not with test complete.
Then I think you need to contact SmartBear support directly. They may be able to provide more expertise. Generally speaking, TestComplete uses the JRE as it is installed on the machine and the JAR files and classes that you designate in JavaBridges for execution. So, if there is something different, then it might be in how TestComplete interprets such things and they would better be able to answer that.
