unit testing - JTA: how to be test JMS and JDBC failures? -

-

We are currently testing the behavior of JATA failure, which receives messages using JMS on the system, He keeps them, and sends the results using another class.

The whole thing is tied together using the spring. Current units use HSQLDB, Apache ActivMac and Bitronics for testing transactions management. Success with this has been limited, as most HSQLDB does not implement XA transactions.

So here's a question: How do I simulate best database failures in transaction unit testing? What is the standard JDBC driver (for Oracle, say) to fail in the middle of a test?

Nb is not a repeating test by pressing the power button :)

It is necessary to decide what you really want to do the test - for example if you want to test that Oracle will deal with beta and XA transactions with the Beatronics, then DAO is joking, Duffim suggested by your help In this case you are not able to connect the connectivity between transactions Need to find a way to break and then see how Batronix / Oracle recovery will handle - eg Exploration results and so on.

Note that in some cases there are actually ways to achieve the same functionality without using the XA transaction. It can be simple, fast and more qualified. For example, in very rare circumstances when messages using MOM and DML are executed in the database, there is a pattern similar to that which removes without XA, two resource managers are still updating.

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.

jquery - SimpleModal Confirm fails to submit form -

-
I am trying to confirm jQuery to show yes / no confirmation when I submit a form. I had modified (in the last list) to capture and block form submissions. However, it only works with jQuery 1.2.6, a recent upgrade stops 1.3.2, if yes is clicked, then by submitting the form. But I can not understand what is wrong / inconsistent in my code now. Demo (which works in both versions of a simple window.href implementation). $ (document) .ready (function () {$ ('input.delete'). Click (function (e) {e.preventDefault (); var target = $ (e .target); Confirm ("Really delete this event?", Function () {target.click ()});});}); How about something like this? The idea of ​​catching clicks (and fire!) On the submitted event is not click event. $ (document) .ready (function () {$ ('# myForm'). Submit (function () {var f = this; Confirm (" Remove? ", Function () {$ (f). Submit ();}) Return; Return the initial session;}}}}; Hope That this is som
