I need design advice on how to bulk smaller XML messages into one big XML message. Basically, we have XML messages that are getting posted to a JMS Topic. When we have 500 messages in the JMS topic, we want to bulk these 500 messages into one big XML message and make one database call(batch update) instead of 500 calls. What are the best ways of doing this. Also, are there other ideas of achieving the same thing. Thanks in advance.
