Theera did you load the jnasmartcardio-0.2.7.jar file into the additional directory? Additional Libraries, the (optional) folder where libraries will be searched for, in addition to the internal libraries folder. You can find this via Tools.
Update: I look into the jar and see that it want to download the javax.smartcardio.CardTerminal, javax.smartcardio.CardTerminals, javax.smartcardio.TerminalFactory, and jnasmartcardio.Smartcardio libraries. You need to make a wrapper to let it work.

I couldnt get it to work with in-line java, seems like java.smartcardio only exports javax.smartcardio to java.base
using javaobject it does work (I think under the hood it sets accessible true)

B4X:
Dim j As JavaObject
Dim factory As JavaObject
j.InitializeStatic("javax.smartcardio.TerminalFactory")
factory = j.RunMethod("getDefault",Null)
Dim terminals As List = factory.RunMethodJO("terminals",Null).RunMethod("list",Null)
Log(j)
Log(factory)
Log(terminals)

Where are getDefault and terminals come from? Please help me explain. There are not java sourcecode, are them? And the
package javax.smartcardio.TerminalFactory is from? (I know only "javax.smartcardio.*)

if you look at the source code jar you will see that the standard java classes (like terminals) are extended. That is why the example from post 3 works. In short: you don't need a wrapper but you can implement your program using the given Java object method from post 3.

The documentation can be found in the file jnasmartcardio-0.2.7-sources.jar after you unzip it after you change the extension from jar to zip.
