  • Shopping Cart Suggestions Needed

    - by Maen
    I am building a small web app for a pharmacy to keep track of sales and stocks, so in short, in one page, the pharmacist will enter a bar-code and the item is displayed, pharmacist enters quantity (price will be automatically calculated) then next item and next and so on, I haven't worked with such a problem before so I would appreciate any advices/tips on how to do it, what to use and wither its already done in some tidy neat way I can just import into my page.

  • Scala println in a for loop

    - by random459
    The following Scala code does just what I expect it to - it prints each line of some_file.txt. import scala.io.Source val lines = Source.fromPath("some_file.txt").mkString for (line <- lines) print(line) If I use println instead of print, I expect to see some_file.txt printed out with double-spacing. Instead, the program prints a newline after every character of some_file.txt. Could someone explain this to me? I'm using Scala 2.8.0 Beta 1.

  • Is it possible to use pure Encrypting and Decrypting keys in asymmetric cryptography instead of priv

    - by macropas
    Is it possible to use pure Encrypting and Decrypting keys instead of private and public keys? As I know in .Net asymmetric RSA implementation private key RSAParameters parameters = (new RSACryptoServiceProvider()).ExportParameters(true) is a superset of public key. And using private key we can both encrypt and decrypt our data. But I need key only for decrypting data. How to do it? I experimented on nulling RSAParameters fields, but RSACryptoServiceProvider object can't import such parameters.

  • Use HTTP PUT to create new cache (ehCache) running on the same Tomcat?

    - by socal_javaguy
    I am trying to send a HTTP PUT (in order to create a new cache and populate it with my generated JSON) to ehCache using my webservice which is on the same local tomcat instance. Am new to RESTful Web Services and am using JDK 1.6, Tomcat 7, ehCache, and JSON. I have my POJOs defined like this: Person POJO: import javax.xml.bind.annotation.XmlRootElement; @XmlRootElement public class Person { private String firstName; private String lastName; private List<House> houses; // Getters & Setters } House POJO: import javax.xml.bind.annotation.XmlRootElement; @XmlRootElement public class House { private String address; private String city; private String state; // Getters & Setters } Using a PersonUtil class, I hardcoded the POJOs as follows: public class PersonUtil { public static Person getPerson() { Person person = new Person(); person.setFirstName("John"); person.setLastName("Doe"); List<House> houses = new ArrayList<House>(); House house = new House(); house.setAddress("1234 Elm Street"); house.setCity("Anytown"); house.setState("Maine"); houses.add(house); person.setHouses(houses); return person; } } Am able to create a JSON response per a GET request: @Path("") public class MyWebService{ @GET @Produces(MediaType.APPLICATION_JSON) public Person getPerson() { return PersonUtil.getPerson(); } } When deploying the war to tomcat and pointing the browser to http://localhost:8080/personservice/ Generated JSON: { "firstName" : "John", "lastName" : "Doe", "houses": [ { "address" : "1234 Elmstreet", "city" : "Anytown", "state" : "Maine" } ] } So far, so good, however, I have a different app which is running on the same tomcat instance (and has support for REST): http://localhost:8080/ehcache/rest/ While tomcat is running, I can issue a PUT like this: echo "Hello World" | curl -S -T - http://localhost:8080/ehcache/rest/hello/1 When I "GET" it like this: curl http://localhost:8080/ehcache/rest/hello/1 Will yield: Hello World What I need to do is create a POST which will put my entire Person generated JSON and create a new cache: http://localhost:8080/ehcache/rest/person And when I do a "GET" on this previous URL, it should look like this: { "firstName" : "John", "lastName" : "Doe", "houses": [ { "address" : "1234 Elmstreet", "city" : "Anytown", "state" : "Maine" } ] } So, far, this is what my PUT looks like: @PUT @Path("/ehcache/rest/person") @Produces(MediaType.APPLICATION_JSON) @Consumes(MediaType.APPLICATION_JSON) public Response createCache() { ResponseBuilder response = Response.ok(PersonUtil.getPerson(), MediaType.APPLICATION_JSON); return response.build(); } Question(s): (1) Is this the correct way to write the PUT? (2) What should I write inside the createCache() method to have it PUT my generated JSON into: http://localhost:8080/ehcache/rest/person (3) What would the command line CURL comment look like to use the PUT? Thanks for taking the time to read this...

  • named/bind zone file parser in C#

    - by Michal Rogozinski
    Hi, I'm looking for a bind/named zone file parser in .NET C#. If there is anything I could import/convert I would be interested too. Unfortunately there's not much, or I'm having troubles finding it. My goal is to make sure a zone file is syntax-errors-free before I push it to the server. I'd appreciate any help or hints. Thanks

    - by knorv
    Assume that the following MySQL files have been restored from a backup tape: tablename.frm tablename.ibd Furthermore, assume that the MySQL installation was running with innodb_file_per_table and that the database was cleanly shutdown with mysqladmin shutdown. Given a fresh install of the same MySQL version that the restored MySQL files were taken from, how do I import the data from tablename.ibd/tablename.frm into this new install?

  • Django manage.py can't find an INSTALLED_APP even though the module is in the path

    - by Rhubarb
    When I run python manage.py shell I get an error about the last app I've added to INSTALLED_APP, namely django_evolution, saying it's an undefined module. This is despite the fact that I've added the path to django_evolution to the system path. In fact right after this error I can run python and do an import on django_evolution and everything is fine. Why isn't django or python seeing this module when clearly it's been setup and even added to the path?

  • Grails Domain.get() returns null for mongo's ObjectId

    - by Shashank Agrawal
    I'm using grails 2.3.5 with mongodb 3.0.1 and no hibernate installed. I've a domain class which uses mongo's ObjectId. import org.bson.types.ObjectId class Category { ObjectId id String name } And has a record in mongo database: { "_id": ObjectId("53f6c34c33a429240e2ab471"), "name": "art", "version": NumberLong("41") } When I do, Category.get(new ObjectId("53f6c34c33a429240e2ab471")) somewhere in grails app, it returns null but when I do Category.get("53f6c34c33a429240e2ab471") it then actually returns the result. Why, get() method does not process ObjectId type?

  • Batch adding attribute to attribute sets

    - by JonB
    I have a Magento installation with around 60 attribute sets. I need to add a new attribute to each of the attribute sets. There doesn't seem to anyway of doing this in the admin control panel. I am sure I can work it out by manually entering the correct fields into the database, but is there a way of doing this through the API or through the Import / Export profiles? Any suggestions would be gladly received.
