I have an XPage app that has been working fine. I upgraded my client from 8.5.3 FP6 to 9.0.1 FP1, built the database and now receive the following error on the 8.5.3 server console:
HTTP JVM: java.lang.NoSuchMethodError: com/ibm/commons/util/io/json/JsonJavaObject.put(Ljava/lang/String;Ljava/lang/Object;)Ljava/lang/Object;
If I rebuild from an 8.5.3 client it runs fine again.
Any suggestions on what I need to do differently using the 9.0.1 Designer client ?
Thanks...
