  • HTTPHeaders Added to Downloaded File - CocoaHTTPServer???

    - by Don
    In an iPhone app where I use cocoahttpserver and take a sqlite database file from the iPhone and download it with a browser to my PC, when I look at the downloaded file using TextEdit, I see the text (below) at the end of the file. This text has apparently no effect on use of the database file, but I would prefer to not add stuff to the database file at all. Any ideas where this header info is coming from in cocoahttpserver and how to stop it? Thanks. ------WebKitFormBoundary3RAcT2SVGhGPnoA6 Content-Disposition: form-data; name="submit.x" 26 ------WebKitFormBoundary3RAcT2SVGhGPnoA6 Content-Disposition: form-data; name="submit.y" 12 ------WebKitFormBoundary001Quvx6Efgaf23y Content-Disposition: form-data; name="submit.x" 30 ------WebKitFormBoundary001Quvx6Efgaf23y Content-Disposition: form-data; name="submit.y" 12 ------WebKitFormBoundaryfHyUUs1p31kBJ3gA Content-Disposition: form-data; name="submit.x" 52 ------WebKitFormBoundaryfHyUUs1p31kBJ3gA Content-Disposition: form-data; name="submit.y" 9

  • Mark text in HTML

    - by Alon
    Hi I have some plain text and html. I need to create a PHP method that will return the same html, but with <span class="marked"> before any instances of the text and </span> after it. Note, that it should support tags in the html (for example if the text is blabla so it should mark when it's bla<b>bla</b> or <a href="http://abc.com">bla</a>bla. It should be incase sensitive and support long text (with multilines etc) either. For example, if I call this function with the text "my name is josh" and the following html: <html> <head> <title>My Name Is Josh!!!</title> </head> <body> <h1>my name is <b>josh</b></h1> <div> <a href="http://www.names.com">my name</a> is josh </div> <u>my</u> <i>name</i> <b>is</b> <span style="font-family: Tahoma;">Josh</span>. </body> </html> ... it should return: <html> <head> <title><span class="marked">My Name Is Josh</span>!!!</title> </head> <body> <h1><span class="marked">my name is <b>josh</b></span></h1> <div> <span class="marked"><a href="http://www.names.com">my name</a> is josh</span> </div> <span class="marked"><u>my</u> <i>name</i> <b>is</b> <span style="font-family: Tahoma;">Josh</span></span>. </body> </html> Thanks.

  • Populate a combo box with one data tabel and save the choice in another.

    - by Scott Chamberlain
    I have two data tables in a data set for example lets say Servers: | Server | Ip | Users: | Username | Password | Server | and there is a foreign key on users that points to servers. How do I make a combo box that list all of the servers. Then how do I make the selected server in that combo box be saved in the data set in the Server column of the users table. EDIT -- I havent tested it yet but is this the right way? this.bsServers.DataMember = "Servers"; this.bsServers.DataSource = this.dataSet; this.bsUsers.DataMember = "FK_Users_Servers"; this.bsUsers.DataSource = this.bsServers; this.serverComboBox.DataBindings.Add(new System.Windows.Forms.Binding("SelectedValue", this.bsUsers, "Server", true)); this.serverComboBox.DataSource = this.bsServers; this.serverComboBox.DisplayMember = "Server"; this.serverComboBox.ValueMember = "Server";

  • What is the structure of a (Data Access) Service Class

    - by jiewmeng
    I learnt that I should be using service classes to persist entities into the database instead of putting such logic in models/controllers. I currently made my service class something like class Application_DAO_User { protected $user; public function __construct(User $user) { $this->user = $user } public function edit($name, ...) { $this->user->name = $name; ... $this->em->flush(); } } I wonder if this should be the structure of a service class? where a service object represents a entity/model? Or maybe I should pass a User object everytime I want to do a edit like public static function edit($user, $name) { $user->name = $name; $this->em->flush(); } I am using Doctrine 2 & Zend Framework, but it shouldn't matter

  • SQLite INTERSECT gives a huge performance decrease

    - by Derk
    I have a query that runs in less than 1 ms: SELECT product_to_value.category AS category, features.name AS featurename, featurevalues.name AS valuename FROM product_to_value, features, featurevalues WHERE product_to_value.category IN(:int, :bla, :bla1) AND product_to_value.feature = features.int AND product_to_value.value = featurevalues.int LIMIT 10 However, when I combine it with another query using INTERSECT, the query now takes more than 250ms: SELECT product_to_value.category AS category, features.name AS featurename, featurevalues.name AS valuename FROM product_to_value, features, featurevalues WHERE product_to_value.category IN(:int, :bla, :bla1) AND product_to_value.feature = features.int AND product_to_value.value = featurevalues.int INTERSECT SELECT product_to_value.category AS category, features.name AS featurename, featurevalues.name AS valuename FROM product_to_value, features, featurevalues WHERE product_to_value.category IN(:int, :bla, :bla1) AND product_to_value.feature = features.int AND product_to_value.value = featurevalues.int LIMIT 10 This can't be right. I've tried several index combinations, for example an index on all columns I use in my query, but to no avail. I've tried compound indexes as well, but they only slow things down even more. I have read a few things about SQLite and how it treats indexes. I know SQLite is capable of delivering sick performance, and surely I must be overlooking something.

  • mySQL - query to combine two tables

    - by W.Gerick
    Hi there, I have two tables. The first one holds information about cities: Locations: locID | locationID | locationName | countryCode | 1 | 2922239 | Berlin | de | 2 | 291074 | Paris | fr | 3 | 295522 | Orlando | us | 3 | 292345 | Tokyo | jp | There is a second table, which holds alternative names for locations. There might be NO alternative name for a location in the Locations table: AlternateNames: altNameID | locationID | alternateName | 1 | 2922239 | Berlino | 2 | 2922239 | Berlina | 3 | 291074 | Parisa | 4 | 291074 | Pariso | 5 | 295522 | Orlandola | 6 | 295522 | Orlandolo | What I would like to get is the locationID, name and the countryCode of a location for a location name search like "Berlin", or "Ber": | locationID | name | countryCode | | 2922239 | Berlin | de | However, if the user searches for "Berlino", I would like to get the alternateName back: | locationID | name | countryCode | | 2922239 | Berlino | de | The "locationName" has a higher priority than the alternateName, if the searchterm matches both. I can't figure out how to build a query to do that. Since the name can come from one of the two tables, it seems quite difficult to me. Any help is really appreciated!

  • Why is ELMAH creating 2 reports for each error?

    - by Chris F
    I have setup ELMAH to create an XML log as well as send an email every time it encounters and unhandled exception in my ASP.NET MVC web application. However, creates 2 xml files for every error and sends to emails, seemingly identical each time. How do I stop this? My relevant web.config configuration sections are below. I thought the duplicate registration system.web and system.webServer may be causing the issue, but that's not the case. <configSections> ... <sectionGroup name="elmah"> <section name="security" requirePermission="false" type="Elmah.SecuritySectionHandler, Elmah" /> <section name="errorLog" requirePermission="false" type="Elmah.ErrorLogSectionHandler, Elmah" /> <section name="errorMail" requirePermission="false" type="Elmah.ErrorMailSectionHandler, Elmah" /> <section name="errorFilter" requirePermission="false" type="Elmah.ErrorFilterSectionHandler, Elmah" /> </sectionGroup> </configSections> <elmah> <security allowRemoteAccess="no"></security> <errorLog type="Elmah.XmlFileErrorLog, Elmah" logPath="~/Logs" /> <errorMail from="[email protected]" to="[email protected]" cc="[email protected]" subject="ELMAH: Site Error" async="true" smtpPort="25" smtpServer="xx.xx.xx.xx" /> </elmah> <system.web> ... <httpHandlers> ... <add verb="POST,GET,HEAD" path="elmah.axd" type="Elmah.ErrorLogPageFactory, Elmah" /> </httpHandlers> <httpModules> ... <add name="ErrorLog" type="Elmah.ErrorLogModule, Elmah"/> <add name="ErrorMail" type="Elmah.ErrorMailModule, Elmah"/> </httpModules> </system.web> <!-- for IIS7 --> <system.webServer> ... <modules runAllManagedModulesForAllRequests="true"> ... <add name="ErrorLog" type="Elmah.ErrorLogModule, Elmah"/> <add name="ErrorMail" type="Elmah.ErrorMailModule, Elmah"/> </modules> <handlers> ... <add verb="POST,GET,HEAD" path="elmah.axd" type="Elmah.ErrorLogPageFactory, Elmah" /> </handlers> </system.webServer>

  • Nhibernate One-to-one mapping issue with child object insert error

    - by TalkDotNet
    Hi, i've being banging my head against the desk all day with the following Nhibernate problem. Each bank account has one (and only one) set of rates associated with it. The primary key of the bank account table, BankAccountID is also a foreign key and the primary key in the rates table. public class BankAccount { public virtual int BankAccountId { get; set; } public virtual string AccountName { get; set;} public virtual AccountRate AccountRate {get;set;} } public class AccountRate { public virtual int BankAccountId { get; set; } public virtual decimal Rate1 { get; set; } public virtual decimal Rate2 { get; set; } } I have the following HBM mappings for BankAccount: <class name="BankAccount" table="BankAccount"> <id name ="BankAccountId" column="BankAccountId"> <generator class="foreign"> <param name="property"> AccountRate </param> </generator> </id> <property name ="AccountName" column="AccountName" /> <one-to-one name="AccountRate" class="AccountRate" constrained="true" cascade="save-update"/> </class> and the following for AccountRate: <class name="AccountRate" table="AccountRate"> <id name ="BankAccountId" column="BankAccountId"> <generator class="native" /> </id> <property name ="Rate1" column="Rate1" /> <property name ="Rate2" column="Rate2" /> </class> An existing BankAccount object can be read from the database with no problem. However, when a new BankAccount is created , the insert statement fails with; Cannot insert the value NULL into column 'BankAccountId' The issue appears to be that the child object , AccountRate is created first and since it hasn't yet got an identifier from its uncreated parent , the insert fails. I think i'm correct in saying that if the AccountRate property on BankAccount was a collection i could use the following ? Inverse=True in order to force the parent to be inserted first. Can anyone help me with this? i Really dont want to use a collection as there is only a unidirectional one to one relationship between these tables. Thanks Paul

  • Ruby Programming Techniques: simple yet not so simple object manipulation

    - by Shyam
    Hi, I want to create an object, let's say a Pie. class Pie def initialize(name, flavor) @name = name @flavor = flavor end end But a Pie can be divided in 8 pieces, a half or just a whole Pie. For the sake of argument, I would like to know how I could give each Pie object a price per 1/8, 1/4 or per whole. I could do this by doing: class Pie def initialize(name, flavor, price_all, price_half, price_piece) @name = name @flavor = flavor @price_all = price_all @price_half = price_half @price_piece = price_piece end end But now, if I would create fifteen Pie objects, and I would take out randomly some pieces somewhere by using a method such as getPieceOfPie(pie_name) How would I be able to generate the value of all the available pies that are whole and the remaining pieces? Eventually using a method such as: myCurrentInventoryHas(pie_name) # output: 2 whole strawberry pies and 7 pieces. I know, I am a Ruby nuby. Thank you for your answers, comments and help!

  • Is the Cloud ready for an Enterprise Java web application? Seeking a JEE hosting advice.

    - by Jakub Holý
    Greetings to all the smart people around here! I'd like to ask whether it is feasible or a good idea at all to deploy a Java enterprise web application to a Cloud such as Amazon EC2. More exactly, I'm looking for infrastructure options for an application that shall handle few hundred users with long but neither CPU nor memory intensive sessions. I'm considering dedicated servers, virtual private servers (VPSs) and EC2. I've noticed that there is a project called JBoss Cloud so people are working on enabling such a deployment, on the other hand it doesn't seem to be mature yet and I'm not sure that the cloud is ready for this kind of applications, which differs from the typical cloud-based applications like Twitter. Would you recommend to deploy it to the cloud? What are the pros and cons? The application is a Java EE 5 web application whose main function is to enable users to compose their own customized Product by combining the available Parts. It uses stateless and stateful session beans and JPA for persistence of entities to a RDBMS and fetches information about Parts from the company's inventory system via a web service. Aside of external users it's used also by few internal ones, who are authenticated against the company's LDAP. The application should handle around 300-400 concurrent users building their product and should be reasonably scalable and available though these qualities are only of a medium importance at this stage. I've proposed an architecture consisting of a firewall (FW) and load balancer supporting sticky sessions and https (in the Cloud this would be replaced with EC2's Elastic Load Balancing service and FW on the app. servers, in a physical architecture the load-balancer would be a HW), then two physical clustered application servers combined with web servers (so that if one fails, a user doesn't loose his/her long built product) and finally a database server. The DB server would need a slave backup instance that can replace the master instance if it fails. This should provide reasonable availability and fault tolerance and provide good scalability as long as a single RDBMS can keep with the load, which should be OK for quite a while because most of the operations are done in the memory using a stateful bean and only occasionally stored or retrieved from the DB and the amount of data is low too. A problematic part could be the dependency on the remote inventory system webservice but with good caching of its outputs in the application it should be OK too. Unfortunately I've only vague idea of the system resources (memory size, number and speed of CPUs/cores) that such an "average Java EE application" for few hundred users needs. My rough and mostly unfounded estimate based on actual Amazon offerings is that 1.7GB and a single, 2-core "modern CPU" with speed around 2.5GHz (the High-CPU Medium Instance) should be sufficient for any of the two application servers (since we can handle higher load by provisioning more of them). Alternatively I would consider using the Large instance (64b, 7.5GB RAM, 2 cores at 1GHz) So my question is whether such a deployment to the cloud is technically and financially feasible or whether dedicated/VPS servers would be a better option and whether there are some real-world experiences with something similar. Thank you very much! /Jakub Holy PS: I've found the JBoss EAP in a Cloud Case Study that shows that it is possible to deploy a real-world Java EE application to the EC2 cloud but unfortunately there're no details regarding topology, instance types, or anything :-(

So far, the concept was: several Message Driven Beans, responsible for different parts of the architecture each MDB has a Session Bean injected, handling the business logic a couple of Entity Beans, providing access to the persistence layer communication between the different parts of the architecture via Request/Reply concept via JMS messages: MDB receives msg containing activity request uses its session bean to execute necessary business logic returns response object in msg to original requester The idea was that by de-coupling parts of the architecture from each other via the message bus, there is no limit to the scalability. Simply start more components - as long as they are connected to the same bus, we can grow and grow. Unfortunately, we're having massive problems with the request-reply concept. Transaction Mgmt seems to be in our way plenty. It seams that session beans are not supposed to consume messages?! Reading http://blogs.sun.com/fkieviet/entry/request_reply_from_an_ejb and http://forums.sun.com/message.jspa?messageID=10338789, I get the feeling that people actually recommend against the request/reply concept for EJBs. If that is the case, how do you communicate between your EJBs? (Remember, scalability is what I'm after) Details of my current setup: MDB 1 'TestController', uses (local) SLSB 1 'TestService' for business logic TestController.onMessage() makes TestService send a message to queue XYZ and requests a reply TestService uses Bean Managed Transactions TestService establishes a connection & session to the JMS broker via a joint connection factory upon initialization (@PostConstruct) TestService commits the transaction after sending, then begins another transaction and waits 10 sec for the response Message gets to MDB 2 'LocationController', which uses (local) SLSB 2 'LocationService' for business logic LocationController.onMessage() makes LocationService send a message back to the requested JMSReplyTo queue Same BMT concept, same @PostConstruct concept all use the same connection factory to access the broker Problem: The first message gets send (by SLSB 1) and received (by MDB 2) ok. The sending of the returning message (by SLSB 2) is fine as well. However, SLSB 1 never receives anything - it just times out. I tried without the messageSelector, no change, still no receiving message. Is it not ok to consume message by a session bean? SLSB 1 - TestService.java @Resource(name = "jms/mvs.MVSControllerFactory") private javax.jms.ConnectionFactory connectionFactory; @PostConstruct public void initialize() { try { jmsConnection = connectionFactory.createConnection(); session = jmsConnection.createSession(false, Session.AUTO_ACKNOWLEDGE); System.out.println("Connection to JMS Provider established"); } catch (Exception e) { } } public Serializable sendMessageWithResponse(Destination reqDest, Destination respDest, Serializable request) { Serializable response = null; try { utx.begin(); Random rand = new Random(); String correlationId = rand.nextLong() + "-" + (new Date()).getTime(); // prepare the sending message object ObjectMessage reqMsg = session.createObjectMessage(); reqMsg.setObject(request); reqMsg.setJMSReplyTo(respDest); reqMsg.setJMSCorrelationID(correlationId); // prepare the publishers and subscribers MessageProducer producer = session.createProducer(reqDest); // send the message producer.send(reqMsg); System.out.println("Request Message has been sent!"); utx.commit(); // need to start second transaction, otherwise the first msg never gets sent utx.begin(); MessageConsumer consumer = session.createConsumer(respDest, "JMSCorrelationID = '" + correlationId + "'"); jmsConnection.start(); ObjectMessage respMsg = (ObjectMessage) consumer.receive(10000L); utx.commit(); if (respMsg != null) { response = respMsg.getObject(); System.out.println("Response Message has been received!"); } else { // timeout waiting for response System.out.println("Timeout waiting for response!"); } } catch (Exception e) { } return response; } SLSB 2 - LocationService.Java (only the reply method, rest is same as above) public boolean reply(Message origMsg, Serializable o) { boolean rc = false; try { // check if we have necessary correlationID and replyTo destination if (!origMsg.getJMSCorrelationID().equals("") && (origMsg.getJMSReplyTo() != null)) { // prepare the payload utx.begin(); ObjectMessage msg = session.createObjectMessage(); msg.setObject(o); // make it a response msg.setJMSCorrelationID(origMsg.getJMSCorrelationID()); Destination dest = origMsg.getJMSReplyTo(); // send it MessageProducer producer = session.createProducer(dest); producer.send(msg); producer.close(); System.out.println("Reply Message has been sent"); utx.commit(); rc = true; } } catch (Exception e) {} return rc; } sun-resources.xml <admin-object-resource enabled="true" jndi-name="jms/mvs.LocationControllerRequest" res-type="javax.jms.Queue" res-adapter="jmsra"> <property name="Name" value="mvs.LocationControllerRequestQueue"/> </admin-object-resource> <admin-object-resource enabled="true" jndi-name="jms/mvs.LocationControllerResponse" res-type="javax.jms.Queue" res-adapter="jmsra"> <property name="Name" value="mvs.LocationControllerResponseQueue"/> </admin-object-resource> <connector-connection-pool name="jms/mvs.MVSControllerFactoryPool" connection-definition-name="javax.jms.QueueConnectionFactory" resource-adapter-name="jmsra"/> <connector-resource enabled="true" jndi-name="jms/mvs.MVSControllerFactory" pool-name="jms/mvs.MVSControllerFactoryPool" />

  • SQL Join to only the maximum row puzzle

Is there a clever way accomplish this in SQL?

  • Search multiple datepicker on same grid

    - by DHF
    I'm using multiple datepicker on same grid and I face the problem to get a proper result. I used 3 datepicker in 1 grid.

  • Ajax/PHP contact form not able to send mail

    - by Steph
    The funny thing is it did work for one evening. I contacted my host, and they are saying there's no reason it should not be working. I have also attempted to test it in Firebug, but it seemed to be sending. And I specifically put the email address (hosted in my domain) on my email safe list, so that is not the culprit either. Would anyone here take a look at it for me? I'd be so grateful. In the header I have: <script type="text/javascript"> $(document).ready(function() { var options = { target: '#alert' }; $('#contactForm').ajaxForm(options); }); $.fn.clearForm = function() { return this.each(function() { var type = this.type, tag = this.tagName.toLowerCase(); if (tag == 'form') return $(':input',this).clearForm(); if (type == 'text' || type == 'password' || tag == 'textarea') this.value = ''; else if (type == 'checkbox' || type == 'radio') this.checked = false; else if (tag == 'select') this.selectedIndex = -1; }); }; </script> Here is the actual form: <form id="contactForm" method="post" action="sendmail.php"> <fieldset> <p>Email Me</p> <div id="fieldset_container"> <label for="name">Your Name:</label> <input type="text" name="name" id="name" /><br /><br /> <label for="email">Email:</label> <input type="text" name="email" id="email" /><br /><br /> <span style="display:none;"> <label for="last">Honeypot:</label> <input type="text" name="last" value="" id="last" /> </span><br /><br /> <label for="message">Comments &amp; Inquiries:</label> <textarea name="message" id="message" cols="" rows=""></textarea><br/> </div> <div id="submit_button"> <input type="submit" name="submit" id="submit" value="Send It" /> </div> </fieldset> </form> <div class="message"><div id="alert"></div></div> Here is the code from my validating page, sendmail.php: <?php // Who you want to recieve the emails from the form. (Hint: generally you.) $sendto = '[email protected]'; // The subject you'll see in your inbox $subject = 'SH Contact Form'; // Message for the user when he/she doesn't fill in the form correctly. $errormessage = 'There seems to have been a problem.

  • ASP.NET Applications Requests/Sec suddenly jumps to a value of about 70 million/sec. on 8 core web

    - by Subhrajit Roy
    We are doing performance testing of an ASP.NET web application with VSTS 2008. We start with 2000 users and slowly ramp up to 5000 users (reaches this user load at around 2.5 hours after the tests start, after this we stay at this user load). The total test duration is of about 6 hours During these runs we have found that the counter Requests/Sec (under category ASP.NET applications) suddenly spikes to a values of 36-72 millions !!!. This keeps on happening intermittently i.e we see this issue once in every 3 performance runs that we give on the same application. In our testing environment we have 4 web servers and interestingly enough we have found that this issue occurs only in the 8 core web servers. Summarizing ... Issue : The counter Requests/Sec (under category ASP.NET Applications) suddenly jumps to a value of about 70 million/sec. on 8 core web servers. This results in an increase in SQL server connections opened by the application. Response time goes for a toss. Error rates also show similar behaviour. However the counter ISAPI Extention Requests/sec does not show any abnormal increase. The graph of this counter almost overlaps with that of counter Requests/Sec till the time of the appearance of the spike.When the spike appears , this counter (ISAPI Extention Requests/sec) actually shows a drop. Test Settings : Performance test run with Visual Studio Team System 2008. Soak test run for 6 hours. Maximum user load 5000 users. This is load is attained at about 2.5 hours into the run and mainted for remaining duration.(i.e for around 3.5 more hrs) This issue is reproducible though happens intermittently. (i.e occurs one in three or four runs) Test Environment : Web site deployed on 4 Web Servers (Windows Server 2003). Of these 2 are 4 core machines and the remaining 2 are 8 core ones. .NET Framework 3.5 SP1 installed on all 4 web servers. Application hosted on IIS 6.0 run in Worker process isolation mode.

  • JPA Cascade delete.

    - by Win Man
    Hi, I am new to JPA/Hibernate. Currently using EJB3, Hibernate/JPA. I have an inheritacnce structure as follows.. @Entity @DiscriminatorColumn(name = "form_type") @Inheritance(strategy = InheritanceType.JOINED) @GenericGenerator(name = "FORMS_SEQ", strategy = "sequence-identity", parameters = @Parameter(name = "sequence", value = "FORMS_SEQ")) @Table(name = "Forms") public abstract class Form{ //code for Form } @Entity @Table(name = "CREDIT_CARDS") @PrimaryKeyJoinColumn(name="CREDIT_CARD_ID") public class CreditCardForm extends Form { //Code for CreditCards. } When I add a row with save the rows are properly inserted into the parent and the child table. However when I try to delete I get an error - 10:19:35,465 ERROR [TxPolicy] javax.ejb.EJBTransactionRolledbackException: Removing a detached instance com.data.entities.form.financial.CreditCard#159? I am using a simple for loop to determine the inheritance type - CreditCard or DebitCard and then calling entityManager.remove(entity). What am I doing wrong? Code for delete.. for(Form content: contents){ if(content.getType()==Type.CREDIT_CARD){ creditCardService.delete((CreditCard)content); } Thanks. WM

  • Problem with JSON, Struts 2 and Ajax.

    - by Javi
    Hello, I have an apllication with Struts 2, Spring and I want to send JSON as a response to an Ajax request, but my server in not sending the JSON in the response. I have this base package: <package name="myApp-default" extends="struts-default"> <result-types> <result-type name="tiles" class="org.apache.struts2.views.tiles.TilesResult" /> <result-type name="json" class="com.googlecode.jsonplugin.JSONResult"> <param name="enableGZIP">true</param> <param name="noCache">true</param> <param name="defaultEncoding">ISO-8859-1</param> </result-type> </result-types> </package> And another package which extends the previous one. <package namespace="/rest" name="rest" extends="myApp-default"> <action name="login" class="restAction" method="login"> <result type="json"/> </action> So I call with jQuery Ajax and debugging it I see it enters in the Action restAction in the method login and it also enters in the method getJsonData() because I have set two breakpoints and the program is stopped first in login and then in getJsonData. public class RestAction extends BaseAction { private String login; private String password; private String jsonData; public String login() { jsonData = "changed"; return Action.SUCCESS; } //I ommit getter/setters for login and password @JSON(name="jsonData") public String getJsonData() { return jsonData; } public void setJsonData(String jsonData) { this.jsonData = jsonData; } } My ajax looks like this: $.ajax({type: 'GET', url: this_url, data: pars, cache:false, success: handleResponse, error: handleError}); With firebug I see that the response to my request is completely void (though I have seen that the data saved in pars variable has been populated to the action and the methods have been executed correctly). And maybe for that reason my ajax enters in my handleError function where xmlHttpRequest.readyState is 4 and xmlHttpRequest.status is 0. Can anyone tell me what may the problem be? Thanks.

  • Spring JPA and persistence.xml

    - by bmw0128
    I'm trying to set up a Spring JPA Hibernate simple example WAR for deployment to Glassfish. I see some examples use a persistence.xml file, and other examples do not. Some examples use a dataSource, and some do not. So far my understanding is that a dataSource is not needed if I have: <persistence-unit name="educationPU" transaction-type="JTA"> <provider>org.hibernate.ejb.HibernatePersistence</provider> <class>com.coe.jpa.StudentProfile</class> <properties> <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver" /> <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/COE" /> <property name="hibernate.connection.username" value="root" /> <property name="show_sql" value="true" /> <property name="dialect" value="org.hibernate.dialect.MySQLDialect" /> </properties> </persistence-unit> I can deploy fine, but my EntityManager is not getting injected by Spring. My applicationContext.xml: <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean"> <property name="persistenceUnitName" value="educationPU" /> </bean> <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="entityManagerFactory" /> </bean> <bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" /> <tx:annotation-driven transaction-manager="transactionManager" /> <bean id="StudentProfileDAO" class="com.coe.jpa.StudentProfileDAO"> <property name="entityManagerFactory" ref="entityManagerFactory" /> </bean> <bean id="studentService" class="com.coe.services.StudentService"> </bean> My class with the EntityManager: public class StudentService { private String saveMessage; private String showModal; private String modalHeader; private StudentProfile studentProfile; private String lastName; private String firstName; @PersistenceContext(unitName="educationPU") private EntityManager em; @Transactional public String save() { System.out.println("*** em: " + this.em); //em is null this.studentProfile= new StudentProfile(); this.saveMessage = "saved"; this.showModal = "true"; this.modalHeader= "Information Saved"; return "successs"; } My web.xml: <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> Are there any pieces I am missing to have Spring inject "em" in to StudentService?

  • Android Market: Application not visible on some Devices

    - by Andreas
    Hello, i have written an application that needs to process outgoing calls. Everything works fine, the application has already a few hundred downloads, but now i get feedback from people who would like to download it, yet cannot find it. I have done some tests and have found that the permission "PROCESS_OUTGOING_CALLS" seems to be responsible for this. If i include it in an app, people with branded phones (at least in Germany) cannot find it, as soon as i remove this permission, everything is fine (when i re-insert it again, the app vanishes again) The weird thing is, that those users can see other apps which use this permission in the market. I have compared my manifest file to outputs from other manifest files and cannot understand why it doesn't work. Here is the manifest file for a test application i wrote to test the problem: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.eventkontor.marketavailabilitytest" android:versionName="1.2" android:versionCode="3" android:installLocation="auto"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".showMain" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> <uses-sdk android:minSdkVersion="3" android:targetSdkVersion="4" /> <uses-permission android:name="android.permission.INTERNET"></uses-permission> <uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"></uses-permission> <uses-permission android:name="android.permission.READ_CONTACTS"></uses-permission> <uses-permission android:name="android.permission.VIBRATE"></uses-permission> <uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission> <supports-screens android:normalScreens="true" android:resizeable="true" android:largeScreens="true" android:smallScreens="false"></supports-screens> </manifest> Does anyone have an idea what i'm doing wrong?
