Invoke sql

Question

I am a new comer to IDM and I am starting a little RnD in Sun Java Identity Manager for an up and coming project. I am creating a rule using Business Process Editor (BPE). I am trying the invoke �<invoke name='sql' class='com.waveset.util.JdbcUtil'>� method with the Map constructor method. ../javadoc/com/waveset/util/JdbcUtil.html#sql(java.util.Map). All I am trying to do below is insert a row into a mysql DB with 4 bind parameters. I have successfully inserted a row with one bind parameter but when I add 2-4 bind parameters it always bombs on me and gives the output below. I can assure you all my values are set including arg 2. Any help would be appreciated.
Also I have turned logging on in MySQL and honestly it is no help because I can only see the prepare statement in the logs. I assume that the exception occurs before the execution.

Answer 1

Tip 1 : turn on tracing for the class com.waveset.util.JdbcUtil (I'm assuming you know how to do this)
Tip 2 : instead of arg1, arg2, etc. try :
<s>parameters</s>
<list>
  <s>john</s>
  <s>smith</s
  <s>[email protected]</s>
  <s>1234</s
</list>
