Answer 1

you will need to provide more information as to what you have done so far. With just the error message - its not possible to pin point the cause of failure.
Here is excellent documentation available on how to write a Java Chain Code for Blockchain: https://www.ibm.com/developerworks/library/j-chaincode-for-java-developers/index.html
I am hoping you have seen the above documentation. Do go through the steps one by one. The documentation is extensive in terms of setting your environment to writing your first chain code in Java.
Hope this helps.
