    <p>Let me say upfront that I'm so ignorant on this topic that I don't even know whether this question has objective answers or not. If it ends up being "not," I'll delete or vote to close the post.</p> <p>Here's the scenario: I just wrote a little web service. It works on my machine. It works on my team lead's machine. It works, as far as I can tell, on every machine except for the production server. The exception that the production server spits out upon failure originates from a third-party JAR file, and is skimpy on information. I search the web for hours, but don't come up with anything useful.</p> <p>So what's the procedure for tracking down an issue that occurs only on production machines? Is there a standard methodology, or perhaps a category/family of tools, for this?</p> <p>The error that inspired this question has already been fixed, but that was due more to good fortune than a solid approach to debugging. I'm asking this question for future reference.</p> <p>EDIT:<br> The answer to this so far seems to be summed up by one word: <strong>logging</strong>. The one issue with logging is that it requires forethought. What if a situation comes up in an existing system with poor logging, or the client is worried about sensitive data and does not want extensive logging systems in the system in the first place?</p> <blockquote> <p>Some related questions:<br> <a href="https://stackoverflow.com/questions/121306/test-accounts-and-products-in-a-production-system">Test accounts and products in a production system</a><br> <a href="https://stackoverflow.com/questions/1129279/running-test-on-production-code-server">Running test on Production Code/Server</a></p> </blockquote>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
