WSO2 BAM REST-API Sample Execution - wso2

Question

I have WSO2BAM V2.2.0 installed on Windows 7 and Cygwin 1.7.18. When I try to run REST-API sample I get the following error in the BAM console.
Can anyone please let me know what can be wrong and how to resolve the issue?

Answer 1

I am not sure but see whether your Java version is JDK 1.7. If so please change to JDK 1.6.

Answer 2

This issue should not be due to Cygwin issue or when publishing data to BAM via rest API. It seems this issue has come when running several hive scripts parallely. How many toolboxes have you installed when you get this issue?

Answer 3

Please try to configure in linux ,it may work.
