Hello all,

I've got studio downloaded and I tried to run it but it didn't work. I don't know if this information may help you but I'm on a Mac running and I have Java Version 8 Update 251 installed. You find below the message I got on Terminal :

I go back to start rapidminer again and again and continue to get the same message. I'm stuck on it. Can someone please help me please? I reinstalled Java several times but the same problem is remaining.

    Hello Manal,

    Whenever I see the following line in a log:
    Caused by: java.lang.ClassNotFoundException: javax.xml.bind.DatatypeConverter
    It means you probably have Java 8 installed but it's not the one you are using. Are you launching RapidMiner Studio from the terminal or double clicking on it?

    If you are launching RapidMiner Studio from the terminal, can you give us the results for the command echo $JAVA_HOME? I'm pretty sure that either it is not set (and java is pointing to your newer Java version) or it is pointing to your newer Java version.

    If it's not pointing to anything, then you should check for the output of which java and give that information back to us to check what is going on, is it ok?

    All the best,

    Yep, that's Java 9+ you are using that is causing this. By the way, you are starting RapidMiner Server here, not Studio.
