  • Java JMS Messaging

    - by London
    Hello, I have a working example of sending message to server and server receiving it via qpid messaging. Here is simple hello world to send to server : http://pastebin.com/M7mSECJn And here is server which receives requests and sends response(the current client doesn't receive response) : http://pastebin.com/2mEeuzrV Here is my property file : http://pastebin.com/TLEFdpXG They all work perfectly, I can see the messages in the qpid queue via Qpid JMX management console. These examples are downloaded from https://svn.apache.org/repos/asf/qpid/trunk/qpid/java/client/example (someone may need it also). I've done Jboss messaging using spring before, but I can't manage to do the same with qpid. With jboss inside applicationsContext I had beans jndiTemplate, conectionFactory, destinationQueue, and jmscontainer like this : <!-- Queue configuration --> <bean id="jndiTemplate" class="org.springframework.jndi.JndiTemplate"> <property name="environment"> <props> <prop key="java.naming.factory.initial">org.jnp.interfaces.NamingContextFactory</prop> <prop key="java.naming.provider.url">jnp://localhost:1099</prop> <prop key="java.naming.factory.url.pkgs">org.jboss.naming:org.jnp.interfaces</prop> <prop key="java.naming.security.principal">admin</prop> <prop key="java.naming.security.credentials">admin</prop> </props> </property> </bean> <bean id="connectionFactory" class="org.springframework.jndi.JndiObjectFactoryBean"> <property name="jndiTemplate" ref="jndiTemplate" /> <property name="jndiName" value="ConnectionFactory" /> </bean> <bean id="queueDestination" class="org.springframework.jndi.JndiObjectFactoryBean"> <property name="jndiTemplate" ref="jndiTemplate" /> <property name="jndiName"> <value>queue/testQueue</value> </property> </bean> <bean id="jmsContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer"> <property name="connectionFactory" ref="connectionFactory" /> <property name="destination" ref="queueDestination" /> <property name="messageListener" ref="listener" /> </bean> and of course sender and listener : Now I'd like to rewrite this qpid example using spring context logic. Can anyone help me?

  • Tearing my hair out - ASP.Net AJAX AutoComplete not working

    - by Dave
    Hope someone can help with this. I've been up and down the web and through this site looking for an answer, but still can't get the Autocomplete AJAX control to work. I've gone from trying to include it in an existing site to stripping it right back to a very basic form and it's still not functioning. I'm having a little more luck using Page Methods rather than a local webservice, so here is my code <%@ Page Language="C#" AutoEventWireup="true" CodeFile="droptest.aspx.cs" Inherits="droptest" %> <%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> <asp:ScriptManager ID="ScriptManager1" EnablePageMethods="true" runat="server"> </asp:ScriptManager> <cc1:AutoCompleteExtender ID="AutoCompleteExtender1" runat="server" MinimumPrefixLength="1" ServiceMethod="getResults" TargetControlID="TextBox1"> </cc1:AutoCompleteExtender> </form> </body> </html> using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.Script.Services; using System.Web.Services; public partial class droptest : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } [WebMethod] public string[] getResults(string prefixText, int count) { string[] test = new string[5] { "One", "Two", "Three", "Four", "Five" }; return test; } } Tried to keep things as simple as possible, but all I get is either the autocomplete dropdown with the source of the page (starting with the <! doctype...) letter by letter, or in IE7 it just says "UNDEFINED" all the way down the list. I'm using Visual Web Developer 2008 at the moment, this is running on Localhost. I think I've exhausted all the "Try this..." options I can find, everything from adding in [ScriptMethod] to changing things in Web.Config. Is there anything obviously wrong with this code? Only other thing that may be having an effect is in Global.asax I do a Context.RewritePath to rewrite URLs - does this have any effect on AJAX? Thanks for any help you can give.

  • mysql unique-constraint

    - by Cypher
    I have two tables -- Variables (id, name) and Variable_Entries (id, var_id, value). I want each variable to have a unique set of entries. If I make the value entry unique then a different variable won't be able to have that same value which is not right. Is there some way to make the value column unique for identical var_id's?

  • How do I prevent Visual Studio from renaming my controls?

    - by Zack Peterson
    If I paste something like <asp:DropDownList ID="DropDownListExpirationDate" runat="server" /> onto an ASPX file that already has a DropDownListExpirationDate control, it will rename the newly-pasted control as DropDownList1. <asp:DropDownList ID="DropDownList1" runat="server" /> I'd rather it didn't. I'd rather is just paste exactly what I copied. Is there a way to disable this feature?

  • Query design in SQL - ORDER BY SUM() of field in rows which meet a certain condition

    - by Christian Mann
    OK, so I have two tables I'm working with - project and service, simplified thus: project ------- id PK name str service ------- project_id FK for project time_start int (timestamp) time_stop int (timestamp) One-to-Many relationship. Now, I want to return (preferably with one query) a list of an arbitrary number of projects, sorted by the total amount of time spent at them, which is found by SUM(time_stop) - SUM(time_start) WHERE project_id = something. So far, I have SELECT project.name FROM service LEFT JOIN project ON project.id = service.project_id LIMIT 100 but I cannot figure out how what to ORDER BY.

  • PHP session not working with JQuery Ajax?

    - by Bolt_Head
    Update, Solved: After all this I found out that I was calling an old version of my code in the update ajax. 'boardControl.php' instead of 'boardUpdate.php' These are the kinds of mistakes that make programing fun. I'm writing a browser gomoku game. I have the ajax statement that allows the player to play a piece. $(document).ready(function() { $("td").live('click',function(){ var value = $(this).attr('id'); $.get('includes/boardControl.php',{play: value, bid: bid}); }); }); value = board square location bid = board ID Before creating a user login for player identification, the server side php had a temporary solution. It would rotate the piece state for the squares when clicked instead of knowing what player to create them for. After creating login stuff I set a session variable for the player's ID. I was hoping to read the session ID from the php during the ajax request and figure out what player they are from there. session_start(); ... $playerId = $_SESSION['char']; $Query=("SELECT p1, p2 FROM board WHERE bid=$bid"); $Result=mysql_query($Query); $p1 = mysql_result($Result,0,"p1"); $p2 = mysql_result($Result,0,"p2"); $newPiece = 0; //*default no player if($playerId == $p1) $newPiece = 1; if($playerId == $p2) $newPiece = 2; For some reason when I run the full web app, the pieces still cycle though, even after I deleted the code to make them cycle. Furthermore, after logging in If i manually load the php page in the browser, it modifies the database correctly (where it only plays pieces belonging to that player) and outputs the correct results. It seems to me that the session is not being carried over when used with Ajax. Yet Google searches tell me that, sessions do work with Ajax. Update: I'm trying to provide more information. Logging in works correctly. My ID is recognized and I printed it out next to the board to ensure that I was retrieving it correctly. The ajax request does update the board. The values passed are correct and confirmed with firebug's console. However instead of placing pieces only for the player they belong to it cycles though the piece states (0,1,2). When manually browsing to boardUpdate.php and putting in the same values sent from the Ajax the results seen in the echo'ed response indicates that the corresponding piece is played each time as intended. Same results on my laptop after fresh load of firefox. Manually browsing to boardUpdate.php without logging in before hand leave the board unchanged (as intended when no user is found in the session). I've double checked the that session_start() is on the php files and double checked the session ID variables. Hope this extra information helps, i'm running out of ideas what to tell you. Should I load up the full code? Update 2: After checking the Ajax responce in fire-bug I realized that the 'play' request does not get a result, and the board is not updated till the next 'update'. I'm still looking into this but I'll post it here for you guys too. boardUpdate.php Notable places are: Refresh Board(line6) Place Piece(line20) function boardUpdate($turnCount) (line63) <?php session_start(); require '../../omok/dbConnect.php'; //*** Refresh Board *** if(isset($_GET['update'])) { $bid = $_GET['bid']; $Query=("SELECT turn FROM board WHERE bid=$bid"); $Result=mysql_query($Query); $turnCount=mysql_result($Result,0,"turn"); if($_GET['turnCount'] < $turnCount) //** Turn increased { boardUpdate($turnCount); } } //*** Place Piece *** if(isset($_GET['play'])) // turn order? player detect? { $squareID = $_GET['play']; $bid = $_GET['bid']; $Query=("SELECT turn, boardstate FROM board WHERE bid=$bid"); $Result=mysql_query($Query); $turnCount=mysql_result($Result,0,"turn"); $boardState=mysql_result($Result,0,"boardstate"); $turnCount++; $playerId = $_SESSION['char']; $Query=("SELECT p1, p2 FROM board WHERE bid=$bid"); $Result=mysql_query($Query); $p1 = mysql_result($Result,0,"p1"); $p2 = mysql_result($Result,0,"p2"); $newPiece = 0; //*default no player if($playerId == $p1) $newPiece = 1; if($playerId == $p2) $newPiece = 2; // if($newPiece != 0) // { $oldPiece = getBoardSpot($squareID, $bid); $oldLetter = $boardState{floor($squareID/3)}; $slot = $squareID%3; //***function updateCode($old, $new, $current, $slot)*** $newLetter = updateCode($oldPiece, $newPiece, $oldLetter, $slot); $newLetter = value2Letter($newLetter); $newBoard = substr_replace($boardState, $newLetter, floor($squareID/3), 1); //** Update Query for boardstate & turn $Query=("UPDATE board SET boardState = '$newBoard', turn = '$turnCount' WHERE bid = '$bid'"); mysql_query($Query); // } boardUpdate($turnCount); } function boardUpdate($turnCount) { $json = '{"turnCount":"'.$turnCount.'",'; //** turnCount ** $bid = $_GET['bid']; $Query=("SELECT boardstate FROM board WHERE bid='$bid'"); $Result=mysql_query($Query); $Board=mysql_result($Result,0,"boardstate"); $json.= '"boardState":"'.$Board.'"'; //** boardState ** $json.= '}'; echo $json; } function letter2Value($input) { if(ord($input) >= 48 && ord($input) <= 57) return ord($input) - 48; else return ord($input) - 87; } function value2Letter($input) { if($input >= 10) return chr($input += 87); else return chr($input += 48); } //*** UPDATE CODE *** updates an letter with a new peice change and returns result letter. //***** $old : peice value before update //***** $new : peice value after update //***** $current : letterValue of code before update. //***** $slot : which of the 3 sqaures the change needs to take place in. function updateCode($old, $new, $current, $slot) { if($slot == 0) {// echo $current,"+((",$new,"-",$old,")*9)"; return letter2Value($current)+(($new-$old)*9); } else if($slot == 1) {// echo $current,"+((",$new,"-",$old,")*3)"; return letter2Value($current)+(($new-$old)*3); } else //slot == 2 {// echo $current,"+((",$new,"-",$old,")"; return letter2Value($current)+($new-$old); } }//updateCode() //**** GETBOARDSPOT *** Returns the peice value at defined location on the board. //****** 0 is first sqaure increment +1 in reading order (0-254). function getBoardSpot($squareID, $bid) { $Query=("SELECT boardstate FROM board WHERE bid='$bid'"); $Result=mysql_query($Query); $Board=mysql_result($Result,0,"boardstate"); if($squareID %3 == 2) //**3rd spot** { if( letter2Value($Board{floor($squareID/3)} ) % 3 == 0) return 0; else if( letter2Value($Board{floor($squareID/3)} ) % 3 == 1) return 1; else return 2; } else if($squareID %3 == 0) //**1st spot** { if(letter2Value($Board{floor($squareID/3)} ) <= 8) return 0; else if(letter2Value($Board{floor($squareID/3)} ) >= 18) return 2; else return 1; } else //**2nd spot** { return floor(letter2Value($Board{floor($squareID/3)}))/3%3; } }//end getBoardSpot() ?> Please help, I'd be glad to provide more information if needed.

  • iPhone JSON Object

    - by Cosizzle
    Hello, I'm trying to create a application that will retrieve JSON data from an HTTP request, send it to a the application main controller as a JSON object then from there do further processing with it. Where I'm stick is actually creating a class that will serve as a JSON class in which will take a URL, grab the data, and return that object. Alone, im able to make this class work, however I can not get the class to store the object for my main controller to retrieve it. Because im fairly new to Objective-C itself, my thoughts are that im messing up within my init call: -initWithURL:(NSString *) value { responseData = [[NSMutableData data] retain]; NSString *theURL = value; NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:theURL]]; [[NSURLConnection alloc] initWithRequest:request delegate:self]; return self; } The processing of the JSON object takes place here: - (void)connectionDidFinishLoading:(NSURLConnection *)connection { [connection release]; NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]; [responseData release]; NSError *jsonError; SBJSON *json = [[SBJSON new] autorelease]; NSDictionary *parsedJSON = [json objectWithString:responseString error:&jsonError]; // NSArray object. listings = [parsedJSON objectForKey:@"posts"]; NSEnumerator *enumerator = [listings objectEnumerator]; NSDictionary* item; // to prove that it does work. while (item = (NSDictionary*)[enumerator nextObject]) { NSLog(@"posts:id = %@", [item objectForKey:@"id"]); NSLog(@"posts:address = %@", [item objectForKey:@"address"]); NSLog(@"posts:lat = %@", [item objectForKey:@"lat"]); NSLog(@"posts:lng = %@", [item objectForKey:@"lng"]); } [responseString release]; } Now when calling the object within the main controller I have this bit of code in the viewDidLoad method call: - (void)viewDidLoad { [super viewDidLoad]; JSON_model *jsonObj = [[JSON_model alloc] initWithURL:@"http://localhost/json/faith_json.php?user=1&format=json"]; NSEnumerator *enumerator = [[jsonObj listings] objectEnumerator]; NSDictionary* item; // while (item = (NSDictionary*)[enumerator nextObject]) { NSLog(@"posts:id = %@", [item objectForKey:@"id"]); NSLog(@"posts:address = %@", [item objectForKey:@"address"]); NSLog(@"posts:lat = %@", [item objectForKey:@"lat"]); NSLog(@"posts:lng = %@", [item objectForKey:@"lng"]); } }

  • 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?

  • load google annotated chart within jquery ui tab content via ajax method

    - by twmulloy
    Hi, I am encountering an issue with trying to load a google annotated chart (http://code.google.com/apis/visualization/documentation/gallery/annotatedtimeline.html) within a jquery ui tab using content via ajax method (http://jqueryui.com/demos/tabs/#ajax). If instead I use the default tabs functionality, writing out the code things work fine: <div id="tabs"> <ul> <li><a href="#tabs-1">Chart</a></li> </ul> <div id="tabs-1"> <script type="text/javascript"> google.load('visualization', '1', {'packages':['annotatedtimeline']}); google.setOnLoadCallback(drawChart); function drawChart() { var data = new google.visualization.DataTable(); data.addColumn('date', 'Date'); data.addColumn('number', 'cloudofinc.com'); data.addColumn('string', 'header'); data.addColumn('string', 'text') data.addColumn('number', 'All Clients'); data.addRows([ [new Date('May 12, 2010'), 2, '2 New Users', '', 3], [new Date('May 13, 2010'), 0, undefined, undefined, 0], [new Date('May 14, 2010'), 0, undefined, undefined, 0], ]); var chart = new google.visualization.AnnotatedTimeLine(document.getElementById('chart_users')); chart.draw(data, { displayAnnotations: false, fill: 10, thickness: 1 }); } </script> <div id='chart_users' style='width: 100%; height: 400px;'></div> </div> </div> But if I use the ajax method for jquery ui tab and point to the partial for the tab, it doesn't work completely. The page renders and once the chart loads, the browser window goes white. However, you can see the tab partial flash just before the chart appears to finish rendering (the chart never actually displays). I have verified that the partial is indeed loading properly without the chart. <div id="tabs"> <ul> <li><a href="ajax/tabs-1">Chart</a></li> </ul> </div>

  • Nhibernate HQL Subselect queries

    - by MegaByte
    Hi I have the following SQL query: select c.id from (select id from customers) c This query has no practical value - I simplified it greatly for the purpose of this post. My question: is it possible have a subquery in the from clause using HQL. If not, can I perhaps query the customers first, kinda like a temp table in sql, and then use the result as the source of the next query? thanks

  • Trying to output variables into repeater

    - by Phil
    I have a downloads box which attaches to the bottom of the page and gives the user file downloads (icon, filesize, description) like this; <asp:Repeater ID="DownloadsRepeater" runat="server"> <HeaderTemplate> <table width="70%"> <tr> <td colspan="3"><h2>Files you can download:</h2></td> </tr> </HeaderTemplate> <ItemTemplate> <tr> <td width="10%"> <a href="/documents/<%=Session("folder")%>/<%=filename%>"> <img src="images/<%=filename%>" border="0" alt="<%=filename%>" /></a> </td> <td width="25%"><% =filesize%></td> <td><a href="/documents/<%=Session("folder")%>/<%=filename%>"><%=description%></a></td> </tr> </table> </ItemTemplate> </asp:Repeater> Then I have code in my code behind to get the data etc like this; s = "select documents.filename, documents.description, documents.filesize from documents, contentdocuments, content where contentdocuments.contentid = content.id and content.id = @contentid and contentdocuments.documentsid = documents.id ORDER BY documents.description" x = New SqlCommand(s, c) x.Parameters.Add("@contentid", SqlDbType.Int) x.Parameters("@contentid").Value = contentid c.Open() r = x.ExecuteReader While r.Read If r.HasRows Then filename = getimage(r("filename")) If r("filesize") > String.Empty Then filesize = (r("filesize") / 1000) & "kb" End If description = r("description") End If DownloadsRepeater.DataSource = r DownloadsRepeater.DataBind() End While The desired result is that the user sees a file download icon, the filesize and the description. with the icon and the description being linked to the file. Can someone point out where I am going wrong and possibly post a sample of correct syntax for achieving this. Thanks!

  • How can arguments to variadic functions be passed by reference in PHP?

    - by outis
    Assuming it's possible, how would one pass arguments by reference to a variadic function without generating a warning in PHP? We can no longer use the '&' operator in a function call, otherwise I'd accept that (even though it would be error prone, should a coder forget it). What inspired this is are old MySQLi wrapper classes that I unearthed (these days, I'd just use PDO). The only difference between the wrappers and the MySQLi classes is the wrappers throw exceptions rather than returning FALSE. class DBException extends RuntimeException {} ... class MySQLi_throwing extends mysqli { ... function prepare($query) { $stmt = parent::prepare($query); if (!$stmt) { throw new DBException($this->error, $this->errno); } return new MySQLi_stmt_throwing($this, $query, $stmt); } } // I don't remember why I switched from extension to composition, but // it shouldn't matter for this question. class MySQLi_stmt_throwing /* extends MySQLi_stmt */ { protected $_link, $_query, $_delegate; public function __construct($link, $query, $prepared) { //parent::__construct($link, $query); $this->_link = $link; $this->_query = $query; $this->_delegate = $prepared; } function bind_param($name, &$var) { return $this->_delegate->bind_param($name, $var); } function __call($name, $args) { //$rslt = call_user_func_array(array($this, 'parent::' . $name), $args); $rslt = call_user_func_array(array($this->_delegate, $name), $args); if (False === $rslt) { throw new DBException($this->_link->error, $this->errno); } return $rslt; } } The difficulty lies in calling methods such as bind_result on the wrapper. Constant-arity functions (e.g. bind_param) can be explicitly defined, allowing for pass-by-reference. bind_result, however, needs all arguments to be pass-by-reference. If you call bind_result on an instance of MySQLi_stmt_throwing as-is, the arguments are passed by value and the binding won't take. try { $id = Null; $stmt = $db->prepare('SELECT id FROM tbl WHERE ...'); $stmt->execute() $stmt->bind_result($id); // $id is still null at this point ... } catch (DBException $exc) { ... } Since the above classes are no longer in use, this question is merely a matter of curiosity. Alternate approaches to the wrapper classes are not relevant. Defining a method with a bunch of arguments taking Null default values is not correct (what if you define 20 arguments, but the function is called with 21?). Answers don't even need to be written in terms of MySQL_stmt_throwing; it exists simply to provide a concrete example.

  • Connection drop problem with Hibernate-mysql-c3p0

    - by user344788
    hi all, This is an issue which I have seen all across the web. I will bring it up again as till now I don't have a fix for the same. I am using hibernate 3. mysql 5 and latest c3p0 jar. I am getting a broken pipe exception. Following is my hibernate.cfg file. com.mysql.jdbc.Driver org.hibernate.dialect.MySQLDialect <property name="hibernate.show_sql">true</property> <property name="hibernate.use_sql_comments">true</property> <property name="hibernate.current_session_context_class">thread</property> <property name="connection.autoReconnect">true</property> <property name="connection.autoReconnectForPools">true</property> <property name="connection.is-connection-validation-required">true</property> <!--<property name="c3p0.min_size">5</property> <property name="c3p0.max_size">20</property> <property name="c3p0.timeout">1800</property> <property name="c3p0.max_statements">50</property> --><property name="hibernate.connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider </property> <property name="hibernate.c3p0.acquireRetryAttempts">30</property> <property name="hibernate.c3p0.acquireIncrement">5</property> <property name="hibernate.c3p0.automaticTestTable">C3P0TestTable</property> <property name="hibernate.c3p0.idleConnectionTestPeriod">36000</property> <property name="hibernate.c3p0.initialPoolSize">20</property> <property name="hibernate.c3p0.maxPoolSize">100</property> <property name="hibernate.c3p0.maxIdleTime">1200</property> <property name="hibernate.c3p0.maxStatements">50</property> <property name="hibernate.c3p0.minPoolSize">10</property>--> My connection pooling is occurring fine.

And I have only select operations . And below is the method which is used most often to execute my select queries. One tricky thing which I am not understanding is in my findById method i am using this line of code getSession().beginTransaction(); without which it gives me an error saying that this cannot happpen without a transaction. But nowhere I am closing this transaction. And thers no method to close a transaction apart from commit or rollback (as far as i know) which are not applicable for select statements. public T findById(ID id, boolean lock) throws HibernateException, DAOException { log.debug("findNyId invoked with ID ="+id+"and lock ="+lock); T entity; getSession().beginTransaction(); if (lock) entity = (T) getSession().load(getPersistentClass(), id, LockMode.UPGRADE); else entity = (T) getSession().load(getPersistentClass(), id); return entity; } Can anyone please suggest what can I do ? I have tried out almost every solution available via googling, on stackoverlow or on hibernate forums with no avail. (And increasing wait_timeout on mysql is not a valid option in my case).

  • Get text of button from IBAction - iPhone

    - by Organiccat
    When an IBAction is called: -(IBAction) onClick1: (id) sender; What is passed in the sender? Since it's hooked up through the IB, I'm not really sure. My question is how to get the text of the button to be the passed object (NSString most likely) so that I could call it inside the action implementation. -(IBAction) onClick1: (id) sender { NSLog(@"User clicked %@", sender); // Do something here with the variable 'sender' }
