  • Using Hibernate with MS ACCESS 2007 Database (Free JDBC Driver)

    - by Quentin T.
    1. I want to do a reverse engineering action with the Hibernate plugin of Eclipse on a MS Access 2007 Database. I'm forced to use a existing MS Access 2007 db. A easy solution is to buy the HXTT. But I want to use a free driver to do my work. So I tried to apply this post : http://www.programmingforfuture.com/2011/06/how-to-use-ms-access-with-hibernate.html (That uses the SQL Server dialect and the driver sun.jdbc.odbc.JdbcOdbcDriver) Unfortunately I have an error that nobody seems to have been on the internet: Exception while generating code Reason : org.hibernate.exception.GenericJDBCException: Error while reading primary key meta data for `c:/myaccessdb.mdb`.TableTest1 I have try to change the primary key on my MS Access DB (deleting all primary key) or to try the reverse engineering on a MS ACCESS with only one table without primary key, but I got all times the problems. 2. The purpose of my job is to transfer daily (weekly) an Oracle 11g database with data from an existing database MS ACCESS 2007. And I thought to use a procedure (Hibernate EJB) Java to be launched automatically every week to do the data transfer. Is this is the best solution ? Configuration : sun.jdbc.odbc.JdbcOdbcDriver v??? Hibernate v3.4 Eclipse ps: If you are a HXTT developer or seller please be indulgent with my post ;). Making money by making people believe that you help, it's bad ! A solution is to use Derby Client driver, as the solution in the post: Does anyone know if Hibernate and java will work effectively with Access? But a clarification of the answer of Rich Seller is required. Could you explain your answer and explain your configuration (hibernate.cfg.xml, persistence.xml and what URL you use in the property name="hibernate.connection.url") without using paying HXTT driver but with the free Derby driver.

  • Remote Email Access?

    - by Tyler
    I have remote email access from an iPhone or my Android phone, but I cannot setup a Windows Email Client to check my email using the exact same information I provided in my phones. The email system is an Exchange 2003 and I hate using the cheap Outlook Web App that it has. User: [email protected] Password: 1234 Server: mail.domain.com And that works for they phones. So why can't I get it to work on my email client? Maybe a DNS problem?

  • RDP access to DirectAccess Server via DirectAccess

    - by crgnz
    I have just setup a Win2008R2 DirectAccess server (and also a Win2008R2 Active Directory server). From the Internet I can Remote Desktop login to the AD server, but I cannot RDP into the DirectAccess server. I can PING both servers and get an IPv6 response. (I can RDP to the DirectAccess server from the internal company network) DirectAccess is configured to allow full intranet access. I think I've hit a mental block, the answer will probably be obvious, but I just can't see it.

  • Please recommend a free stealth remote access solution for internal network

    - by Nathaniel_613
    Hi, I need to have ability to stealthfully access, view, and control a few dozen PC's on my company's network. I would need a control panel window, so I can instantly connect to any of the users. Please recommend a secure solution, that will not make us vulnerable to viruses and hackers. All of the PC's have dynamic IP addresses, so I may have to use the DNS name or have a solution that uses web. Thank you very much, Nathaniel.

  • How to access localhost from by ip address?

    - by Malte Werschy
    I am trying to access localhost by my ip address. My ip address is/was http://217.164.79.62/ (It is set to be automatically assigned so it keeps changing). When I enter http://localhost/ into the browser I get the xampp homepage. However when I enter http://217.164.79.62/ into my browser I get the following message: The server 217.164.79.62:80 requires a username and password. User Name: Password: How do I get the username and password?

  • Setting the secure flag on cookies from Outlook Web Access

    - by Cheekysoft
    I'm running Exchange 2007 SP3 which is exposing outlook web access over only HTTPS. However the server delivers the sessionid cookie without the secure flag set. Even though I don't have port 80 open, this cookie is still vulnerable to being stolen over port 80 in the event of a man-in-the-middle attack. It also contributes to a PCI-DSS failure Does anyone know if I can persuade the web server/application to set the secure flag?

  • Saving table yields "Record is too large" in Access

    - by C. Ross
    I have an access database that I gave to a user (shame on my head). They were having trouble with some data being too long, so I suggested changing several text fields to memo fields. I tried this in my copy and it worked perfectly, but when the user tries it they get a "Record is too large" messagebox on saving the modified table design. Obviously the same record is not too large in my database, why would it be in theirs?

  • Install Second Copy of Windows in a Partition, Block Access to other Partitions

    - by Mat
    I want to lend my computer to my flatmate so that he can play some games for which his computer is underpowered. Is it possible to install a second copy of Windows 7 into a separate partition and configure it such that it has no access to the other partitions and disks on the computer, the ones that I use in my main Windows install? I'm not concerned about security, just want to avoid him accidentially messing with my data somehow. Can I do that?

  • Can access SSH but can't access cPanel web server

    - by Tom
    I've built a Cent OS 6.0 vps and then i've installed the latest cPanel/WHM. This isn't my first installation but i've noticed something weird especially that i've never used the 6.0 version.. when i tried to install cPanel, it didn't recognize wget so installed it, then cPanel said that Perl isn't installed, i've installed that and the installation went well since then. Now, when i've tried to access the server via the browser with the IP Adress as i've used to, it didn't work, it was just loading forever, i tried the 2087 port, still the same. but SSH works. I've also tried the commands to start the server manually but none of them worked. How to fix that?

  • SQL to select random mix of rows fairly [migrated]

    - by Matt Sieker
    Here's my problem: I have a set of tables in a database populated with data from a client that contains product information. In addition to the basic product information, there is also information about the manufacturer, and categories for those products (a product can be in one or more categories). These categories are then referred to as "Product Categories", and which stores these products are available at. These tables are updated once a week from a feed from the customer. Since for our purposes, some of the product categories are the same, or closely related for our purposes, there is another level of categories called "General Categories", a general category can have one or more product categories. For the scope of these tables, here's some rough numbers: Data Tables: Products: 475,000 Manufacturers: 1300 Stores: 150 General Categories: 245 Product Categories: 500 Mapping Tables: Product Category -> Product: 655,000 Stores -> Products: 50,000,000 Now, for the actual problem: As part of our software, we need to select n random products, given a store and a general category. However, we also need to ensure a good mix of manufacturers, as in some categories, a single manufacturer dominates the results, and selecting rows at random causes the results to strongly favor that manufacturer. The solution that is currently in place, works for most cases, involves selecting all of the rows that match the store and category criteria, partition them on manufacturer, and include their row number from within their partition, then select from that where the row number for that manufacturer is less than n, and use ROWCOUNT to clamp the total rows returned to n. This query looks something like this: SET ROWCOUNT 6 select p.Id, GeneralCategory_Id, Product_Id, ISNULL(m.DisplayName, m.Name) AS Vendor, MSRP, MemberPrice, FamilyImageName from (select p.Id, gc.Id GeneralCategory_Id, p.Id Product_Id, ctp.Store_id, Manufacturer_id, ROW_NUMBER() OVER (PARTITION BY Manufacturer_id ORDER BY NEWID()) AS 'VendorOrder', MSRP, MemberPrice, FamilyImageName from GeneralCategory gc inner join GeneralCategoriesToProductCategories gctpc ON gc.Id=gctpc.GeneralCategory_Id inner join ProductCategoryToProduct pctp on gctpc.ProductCategory_Id = pctp.ProductCategory_Id inner join Product p on p.Id = pctp.Product_Id inner join StoreToProduct ctp on p.Id = ctp.Product_id where gc.Id = @GeneralCategory and ctp.Store_id=@StoreId and p.Active=1 and p.MemberPrice >0) p inner join Manufacturer m on m.Id = p.Manufacturer_id where VendorOrder <=6 order by NEWID() SET ROWCOUNT 0 (I've tried to somewhat format it to make it cleaner, but I don't think it really helps) Running this query with an execution plan shows that for the majority of these tables, it's doing a Clustered Index Seek. There are two operations that take up roughly 90% of the time: Index Seek (Nonclustered) on StoreToProduct: 17%. This table just contains the key of the store, and the key of the product. It seems that NHibernate decided not to make a composite key when making this table, but I'm not concerned about this at this point, as compared to the other seek... Clustered Index Seek on Product: 69%. I really have no clue how I could make this one more performant. On categories without a lot of products, performance is acceptable (<50ms), however larger categories can take a few hundred ms, with the largest category taking 3s (which has about 170k products). It seems I have two ways to go from this point: Somehow optimize the existing query and table indices to lower the query time. As almost every expensive operation is already a clustered index scan, I don't know what could be done there. The inner query could be tuned to not return all of the possible rows for that category, but I am unsure how to do this, and maintain the requirements (random products, with a good mix of manufacturers) Denormalize this data for the purpose of this query when doing the once a week import. However, I am unsure how to do this and maintain the requirements. Does anyone have any input on either of these items?

  • Drawing random smooth lines contained in a square [migrated]

    - by Doug Mercer
    I'm trying to write a matlab function that creates random, smooth trajectories in a square of finite side length. Here is my current attempt at such a procedure: function [] = drawroutes( SideLength, v, t) %DRAWROUTES Summary of this function goes here % Detailed explanation goes here %Some parameters intended to help help keep the particles in the box RandAccel=.01; ConservAccel=0; speedlimit=.1; G=10^(-8); % %Initialize Matrices Ax=zeros(v,10*t); Ay=Ax; vx=Ax; vy=Ax; x=Ax; y=Ax; sx=zeros(v,1); sy=zeros(v,1); % %Define initial position in square x(:,1)=SideLength*.15*ones(v,1)+(SideLength*.7)*rand(v,1); y(:,1)=SideLength*.15*ones(v,1)+(SideLength*.7)*rand(v,1); % for i=2:10*t %Measure minimum particle distance component wise from boundary %for each vehicle BorderGravX=[abs(SideLength*ones(v,1)-x(:,i-1)),abs(x(:,i-1))]'; BorderGravY=[abs(SideLength*ones(v,1)-y(:,i-1)),abs(y(:,i-1))]'; rx=min(BorderGravX)'; ry=min(BorderGravY)'; % %Set the sign of the repulsive force for k=1:v if x(k,i)<.5*SideLength sx(k)=1; else sx(k)=-1; end if y(k,i)<.5*SideLength sy(k)=1; else sy(k)=-1; end end % %Calculate Acceleration w/ random "nudge" and repulive force Ax(:,i)=ConservAccel*Ax(:,i-1)+RandAccel*(rand(v,1)-.5*ones(v,1))+sx*G./rx.^2; Ay(:,i)=ConservAccel*Ay(:,i-1)+RandAccel*(rand(v,1)-.5*ones(v,1))+sy*G./ry.^2; % %Ad hoc method of trying to slow down particles from jumping outside of %feasible region for h=1:v if abs(vx(h,i-1)+Ax(h,i))<speedlimit vx(h,i)=vx(h,i-1)+Ax(h,i); elseif (vx(h,i-1)+Ax(h,i))<-speedlimit vx(h,i)=-speedlimit; else vx(h,i)=speedlimit; end end for h=1:v if abs(vy(h,i-1)+Ay(h,i))<speedlimit vy(h,i)=vy(h,i-1)+Ay(h,i); elseif (vy(h,i-1)+Ay(h,i))<-speedlimit vy(h,i)=-speedlimit; else vy(h,i)=speedlimit; end end % %Update position x(:,i)=x(:,i-1)+(vx(:,i-1)+vx(:,i))/2; y(:,i)=y(:,i-1)+(vy(:,i-1)+vy(:,1))/2; % end %Plot position clf; hold on; axis([-100,SideLength+100,-100,SideLength+100]); cc=hsv(v); for j=1:v plot(x(j,1),y(j,1),'ko') plot(x(j,:),y(j,:),'color',cc(j,:)) end hold off; % end My original plan was to place particles within a square, and move them around by allowing their acceleration in the x and y direction to be governed by a uniformly distributed random variable. To keep the particles within the square, I tried to create a repulsive force that would push the particles away from the boundaries of the square. In practice, the particles tend to leave the desired "feasible" region after a relatively small number of time steps (say, 1000)." I'd love to hear your suggestions on either modifying my existing code or considering the problem from another perspective. When reading the code, please don't feel the need to get hung up on any of the ad hoc parameters at the very beginning of the script. They seem to help, but I don't believe any beside the "G" constant should truly be necessary to make this system work. Here is an example of the current output: Many of the vehicles have found their way outside of the desired square region, [0,400] X [0,400].
