JPA/ORM vs JDBC for performance limited machines -

-

We are creating a small application that will be deployed on very limited machines. They only have 256 MB of RAM.

I would like to use JPA because it simplifies the code and removes the need for JDBC ResultText code. However, should the upper part of JPA be the factor of such small machines? I am currently thinking of using toplink, which comes in a 2.5 MB jar file.

We have only limited numbers, so JDBC code will not be very difficult. But JPA makes code very good.

Cheers.

The JPA / ORM display will always be equal to or equal to the JDBC in runtime because they are both based on JDBC .

As you noted, the development time of the big lift received from the JAPA / ORM is time.

I would like to use JPA because it simplifies the code and JDBC results remove the need for the code.

I'm not sure that I understand this statement. JPA will use a result set behind the scenario; You will not write it now, the mapping of objects from ResultSet is explained in XML or annotation.

If you are actually bound to memory, then you have to pass JPA and hand code to JDBC

In that case you can see Spring JDBC because it is very much for JDBC support Nice design that makes it very simple.

256 MB RAM? You will have a hard time using any third party libraries.

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.
