  • Setting column length of a Long value with JPA annotations

    - by Gearóid
    Hi, I'm performing a little database optimisation at the moment and would like to set the column lengths in my table through JPA. So far I have no problem setting the String (varchar) lengths using JPA as follows: @Column(unique=true, nullable=false, length=99) public String getEmail() { return email; } However, when I want to do the same for a column which is of type Long (bigint), it doesn't work. For example, if I write: @Id @Column(length=7) @GeneratedValue(strategy = GenerationType.AUTO) public Long getId() { return id; } The column size is still set as the default of 20. Are we able to set these lengths in JPA or am I barking up the wrong tree? Thanks, Gearoid.

I need to get a substring of this string and substring will fit in 100 pixels. Ex: substring "Please help me to sol" is fit in 100 pixels. Please help me how to estimate a substring like this. Thanks. My application is Win Forms and C#.

  • How does a WCF server inform a WCF client about changes? (Better solution then simple polling, e.g.

    - by Ian Ringrose
    see also "WCF push to client through firewall" I need to have a WCF client that connect to a WCF server, then when some of the data changes on the server the clients need to update its display. As there is likely to be a firewall between the clients and the server. All communications must be over HTTP The server can not make an (physical) outgoing call to the client. As I am writing both the client and the server I do not need to limit the solution to only using soap etc. I am looking for built in surport for "long polling" / "Comet" etc Thanks for the most informative answer from Drew Marsh on how to implement long polling in WCF. However I thought the main “selling point” of WCF was that you could do this sort of thing just by configuring the channels to be used in the config file. E.g I want a channel that logically two way but physically incoming only.

  • Handling over-long UTF-8 sequences

    - by Grant McLean
    I've just been reworking my Encoding::FixLatin Perl module to handle over-long utf8 byte sequences and convert them to the shortest normal form. My question is quite simply "is this a bad idea"? A number of sources (including this RFC) suggest that any over-long utf8 should be treated as an error and rejected. They caution against "naive implementations" and leave me with the impression that these things are inherently unsafe. Since the whole purpose of my module is to clean up messy data files with mixed encodings and convert them to nice clean utf8, this seems like just one more thing I can clean up so the application layer doesn't have to deal with it. My code does not concern itself with any semantic meaning the resulting characters might have, it simply converts them into a normalised form. Am I missing something. Is there a hidden danger I haven't considered?

  • Classes missing if application runs for a long time

    - by Rogach
    I have a funny problem - if my application runs for a long time ( 20h), then sometimes I get NoClassDefFound error - seems like JVM decided that the class is not going to be used anyway and GCd it. To be a bit more specific, here's an example case: object ErrorHandler extends PartialFunction[Throwable,Unit] { def isDefinedAt(t: Throwable) = true def apply(e: Throwable) =e match { // ... handle errors } } // somewhere else in the code... try { // ... long running code, can take more than 20 hours to complete } catch (ErrorHandler) And I get the following exception: Exception in thread "main" java.lang.NoClassDefFoundError: org/rogach/avalanche/ErrorHandler$ If that try/catch block runs for smaller amounts of time, everything works as expected. If anyone is interested, here is the codebase in question: Avalanche I need to note that I saw this and similar problems only on Cent OS 5 machines, using JRE 6u26 and Scala 2.9.1 / 2.9.2. What could be the cause of this problem?

  • Store a long string into mult array

    - by QLiu
    Hello All, I have a long string arrays, which looks like that var callinfo_data=new Array( "1300 135 604#<b>Monday - Friday: 9:00 a.m. to 5:30 p.m. AEST</b>", //Australia .. "0844000040#<b>lunedì-venerdì ore 10:00 - 17:00 CET</b>", //Switzerland (it) "212 356 9707#<b>Hafta içi her gün: 10:00 - 18:00</b>", //Turkey "08451610009#<b>Monday - Friday: 9:00 a.m. to 6:30 p.m. GMT</b>", //UK "866 486 6866#<b>Monday - Friday: 7:00 a.m. to 11:00 p.m. EST</b><br />Saturday: 9:00 a.m. to 8:00 p.m. EST", //USA "+31208501004#<b>Monday - Friday: 9:00 a.m. to 7:30 p.m. GMT+1</b>", //other countries " # "); As you see, it contact Phone number and open time. I can use split to separet them into info=callinfo_data[n].split("#"); two sections, And then i can represent them in HTML like "<div id ='phoneNumber'>"+info[0]+"</div><div id='openTime'>"+info[1]+"</div>" But my display phone number function will read the cookie variables, and then select the right contact info to display. Like, phone=callinfo_data[2].split("#"); if (locale == 'UK') details = phone[0]+ build_dropdown(locale); else if (locale == 'fr') details = 'French Contact Details<br>'+build_dropdown(locale); else if (locale == 'be') details = 'Belgian Contact Details<br>'+ build_dropdown(locale); else details = 'Unknown Contact Detail'; writeContactInfo(details); My questions are how I can build a function to load phone number and time based on my cookie variables, UK in a smart way. I can hard code everything, but i think it is too silly. I have to write a long code like: phone1= allinfo_data[0].split("#"); phone1= allinfo_data[1].split("#"); ... etc Second questions, how can I load this long arrays into easy access multi arrays? Thank you Regards, Qing

  • How Long: Converting HTML to Jooma pages

    - by George
    Hello Everyone, I would really appreciate your help with finding out how long it takes a 1-3 year experenced programmer to convert a few HTML pages into joomla 1.5 dynamic pages. I know that some of it depends on how complex the pages are but i'm talking about average pages. That's my first question, my other question is how long will it take a 1-3 year experenced programmer to install all of these componants: Video module, photo gallery module, vertuemart shopping cart. I pay programmers to do this work but i have to make as sure as i can that i'm not over paying them. Thanks in advance for answering these two questions...George

  • Converting IPv4 or IPv6 address to a long for comparisons

    - by Justin Akehurst
    In order to check if an IPv4 or IPv6 address is within a certain range, I've got code that takes an IPv4 address, turns that into a long, then does that same conversion on the upper/lower bound of the subnet, then checks to see if the long is between those values. I'd like to be able to do the same thing for IPv6, but saw nothing in the Python 2.6 standard libraries to allow me to do this, so I wrote this up: import socket, struct from array import array def ip_address_to_long(address): ip_as_long = None try: ip_as_long = socket.ntohl(struct.unpack('L', socket.inet_pton(socket.AF_INET, address))[0]) except socket.error: # try IPv6 try: addr = array('L', struct.unpack('!4L', socket.inet_pton(socket.AF_INET6, address))) addr.reverse() ip_as_long = sum(addr[i] << (i * 32) for i in range(len(addr))) except socket.error as se: raise ValueError('Invalid address') except Exception as e: print str(e) return ip_as_long My question is: Is there a simpler way to do this that I am missing? Is there a standard library call that can do this for me?

  • printing long compilation lines with MS NMAKE

    - by Elazar Leibovich
    I have a legacy MS NMAKE Makefile I need to fix a few bugs in. There are some very long command lines I wish to debug that are being executed using the NMAKE trick of "inline files": dep: cmd @<<tmpfilename cmd_args.. << When changing the line to dep: echo cmd @<<tmpfilename cmd_args.. << NMAKE complains that the line is too long. Is there any other trick I can apply in order to view the command line NMAKE is actually executing?

  • wide and long table in latex

    - by Tim
    Hi, I have a wide and long table. I am not sure how to put it in my thesis. Since it is wide, sidewaystable may be the choice. Meanwhile it is also to long to fit in one page, so longtable comes into my mind. However, I cannot make sideaystable and longtable working together for one table, e.g. \begin{sidewaystable} \begin{longtable}{| c ||c| c| c |c| c|| c |c| c|c|c| } \caption{A glance of images.} \centering % table content \end{longtable} \end{sidewaystable} What shall I do? Thanks and regards!

  • Force redraw before long running operations

    - by Joshua
    When you have a button, and do something like: Private Function Button_OnClick Button.Enabled = False [LONG OPERATION] End Function Then the button will not be grayed, because the long operation prevents the UI thread from repainting the control. I know the right design is to start a background thread / dispatcher, but sometimes that's too much hassle for a simple operation. So how do I force the button to redraw in disabled state? I tried .UpdateLayout() on the Button, but it didn't have any effects. I also tried System.Windows.Forms.DoEvents() which normally works when using WinForms, but it also had no effect.

  • I'm asked to tune a long starting app into a short time period

    - by Jason
    Hi, I'm asked to shorten the startup period of a long starting app, however I have also to obligate to my managers to the amount of time i will reduce the startup - something like 10-20 seconds. As i'm new in my company I said I can obligate with timeframe of months (its a big server and I'm new and i plan to do lazy load + performance tuning). that answer was not accepted I was required to do some kind of a cache to hold important data in another server and then when my server starts up it would reach all its data from that cache - I find it a kind of a workaround and i don't really like it. do you like it? what do you think I should do? any suggestions? PS when i profiled the app i saw many small issues that make the startup long (like 2 minutes) it would not be a short process to fix all and to make lazy load. Any kind of suggestions would help. language - java. Thanks

  • C++ : size of int, long, etc...

    - by Jérôme
    I'm looking for detailed informations regarding the size of basic C++ types. I know that it depends on the architecture (16 bits, 32 bits, 64 bits) and the compiler. But are there any standards ? I'm using Visual Studio 2008 on a 32 bit achitecture. Here is what I get : char : 1 byte short : 2 bytes int : 4 bytes long : 4 bytes float : 4 bytes double : 8 bytes I tried to find, without much success, reliable informations telling the sizes of char, short, int , long, double, float (and other types I don't think of) under different architecture and compiler.

  • How long until programming becomes a professionally certified (and respected as such) skill such as

    - by Michael Campbell
    Given Toyota's recent issues and the ENORMOUS amount of safety that is being relegated to computers, how long do you think it will be before programming, or perhaps programming certain things (embedded transportation software, (air) traffic control, electrical grid, hospital equipment, nuclear plant security, planes, etc.) becomes regulated? And/or, how long before there will be certain regulated certifications before you can call yourself a "software developer", like Architects and Engineers have now? (NB: I'm from the US, so I don't know how it works in other countries; please forgive my ignornace.)

  • Updating table takes very long time

    - by rrejc
    Hi all, I have a table in MsSQL Server 2008 (SP2) containing 30 millios of rows, table size 150GB, there are a couple of int columns and two nvarchar(max) columns: one containing text (from 1-30000 characters) and one containg xml (up to 100000 characters). Table doesn't have any primary keys or indexes (its is a staging table). So atm I am running a query: UPDATE [dbo].[stage_table] SET [column2] = SUBSTRING([column1], 1, CHARINDEX('.', [column1])-1); the query is running for 3 hours (and it is still not completed), which I think is too long. Is It? I can see that there is constant read rate of 5MB/s and write rate of 10MB/s to .mdf file. How can I find out why the query is running so long? The "server" is i7, 24GB of ram, SATA disks on RAID 10. Many thanks!

  • C# - How to convert 10 bytes to unsigned long

    - by Justin
    Hey, I have 10 bytes - 4 bytes of low order, 4 bytes of high order, 2 bytes of highest order - that I need to convert to an unsigned long. I've tried a couple different methods but neither of them worked: Try #1: var id = BitConverter.ToUInt64(buffer, 0); Try #2: var id = GetID(buffer, 0); long GetID(byte[] buffer, int startIndex) { var lowOrderUnitId = BitConverter.ToUInt32(buffer, startIndex); var highOrderUnitId = BitConverter.ToUInt32(buffer, startIndex + 4); var highestOrderUnitId = BitConverter.ToUInt16(buffer, startIndex + 8); return lowOrderUnitId + (highOrderUnitId * 100000000) + (highestOrderUnitId * 10000000000000000); } Any help would be appreciated, thanks!

  • Java Web Server with Jetty - TCP Connections Taking Long

    - by daysleeper
    I have an application with fairly high traffic (20K req/min) running on the JVM with a Jetty servlet container on Ubuntu. Below is my Jetty configuration: 10 20 2000 2 When I analyze the network traffic, I realize that sometimes it is taking long to establish TCP connections on the port that Jetty is running. The long connections are varying between 3.0s and 9.0s. The port is configured to accept MAX number of TCP connections. Do you know what might be causing the delay in accepting connections? Thanks

  • Process AJAX response with long runing tasks

    - by mpz
    I have long time task in controller action. I use delayed job for it. (Also in heroku it is good practice for perfomance - dyno must work for small time in each request) But my client need result of it work and users can wait on that task. It is more clear: no any addition models or records in it, simple view and js... I think about such way: On client run AJAX with very long timeout (5 min for example) Client make request to server as usual On controller in action1 def start_work (with delay work setup) i need NO any response to client After work performs (delay job finished) i need run new action2 with response to client Client recieve response after about 1-5 min It is possible?

  • SqlDataAdapter.Fill suddenly taking a long time

    - by WraithNath
    I have an application with a central DataTier that can execute a query to a data table using an SQLDataAdapter. None of this code has changed but now all queries are taking at least 10x as long to execute a query returning even one record. The only difference is that I have been using the app in a VM but the issue has started mid way through using the application. eg, the speed issue has not manifested itself from the start of using the VM, rather half way through. Has anyone else had an issue with the SQL Data Adapter taking a long time to fill for no reason? executing the query in Management studio it runs in less than a second. Firewalls are disabled

  • Java date long value changed after insert, select query

    - by StackExploded
    AFAIK, java Date type is independent from Timezone which means that it represents specific moment of time as long typed value. I found really weird thing here. This is the original value i tried to insert. (http-0.0.0.0-9080-4) 1352955600000 <-- long integer. (http-0.0.0.0-9080-4) Thu Nov 15 00:00:00 EST 2012 <-- User Friendly Format. After i finished inserting into Oracle 11g database, the value has changed! (http-0.0.0.0-9080-4) 1352952000000 (http-0.0.0.0-9080-4) Wed Nov 14 23:00:00 EST 2012 How could this happen?? The more weird thing is it only happens specific environments such as Jboss. I'm currently using below environments. java 1.6 ibatis 2.34 jboss-5.1 (server) tomcat 6.0 (local) oracle 11g Is there anybody who can give me a clue or link to be helpful? it really bugging me!!
