The first one may be a nice way. Pagination: count the queue size, view the section. You neednt care about headers or whole messages.

Browsing should support pagination (similar to databases) as well as loading only the headers during browsing. Loading the full body should only take place when a single message is inspected. I can think of the following three alternatives and would be happy to hear your thoughts: 1) Browsing the DLQ directly via the (JMX) QueueBrowser. Pagination and loading only the headers is not supported. However, using the file-based cursor as suggested here (http://activemq.2283324.n4.nabble.com/template/NamlServlet.jtp?macro=search_page&node=2341804&query=maza&n=2341804) may circumvent a resource shortage problem for a certain number of messages. 2) Using the JDBC persistence. Advantages: This would allow to browse the underlying database directly. Disadvantage: JDBC must be used. 3) Moving all messages from the DLQ to a database using a short, custom Camel route. In this case, the DLQ is used as a kind of sink. The Camel route would be responsible for moving all messages to a database using JDBC/JPA. Advantages: KahaDB can be used. Browsing/Pagination of messages is supported by the underlying database. Disadvantages: Moving and potential re-queuing involves custom Camel code. I am personally tending to approach n°3 and I am looking forward to hear your opinions and/or other approaches for tackling this issue.
