jdbc - Spring JdbcTemplate returns empty result when there should be a valid result -

-

I am using SimpleJdbcDaoSupport object to access DB resources. I have a query that is often executed against the database to detect a record with a particular key. After executing the same question several times, I start getting empty results for several reasons, even if the record is present in the database.

Any idea which can cause this behavior? 

  daoSupport.getJdbcTemplate (). Query (this.getConsumerTokenQueryStatement (), Parameters, this.rowMapper); Public static class token Sewaonaromahapar Romamapr apply (public object Mancitrrv (Rijltsset RS, brick row Num) throws {default Lobhandlr Lobhandlr = new default Lobhandlr (Skyuelikseshn); Luhhandr KgetBlobAsBytes (RS, 1);}}

If it is not related to your code so the fact it may be that another transaction The row you searched for something ( As an update) and due to isolation between transactions you can not see your line one transaction may change, but your line is still not reduced, while at the same time The second one is searching for it, but it can view only the committed rows, it does not see your line.

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
