Hi, I'm using the JSONWeb Token module. In Mendix modeler 7.10 this module was/is working fine. I've upgraded Mendix to 7.11 and now the token gives the following error: java.lang.NoSuchMethodError: org.apache.commons.codec.binary.Base64.encodeBase64URLSafeString([B)Ljava/lang/String; Does someone know how to fix this problem? Edit I already tried to update / reinstall the module and some other modules. I also looked for duplicates in the userlib folder and deleted the duplicate ones. Both did not do anything unfortunately. Thanks!
Did you really didn't do anything else, like updating a module? Most of the time, these problems with Java occur because of duplicate files or different versions of the same library. Maybe Mx 7.11 included a Apache Commons library themselves. Could you verify which lib-files you have in the userlib folder which have Apache and Commons in its name? (like org.apache.commons.lang3.jar). Try to delete duplicates and then try again.
