• Parametrizing max value of a jQuery ui slider

  - by Gandalf StormCrow

  I'm trying to create this slider http://jqueryui.com/demos/slider/#rangemax Is it possible to parametrize the max value? For ex: $("#slider-range-max").slider({ range: "max", min: 1, max: maxValue, value: 2, slide: function(event, ui) { $("#amount").val(ui.value); } }); Is it possible to pass maxValue value, when I click on something? After its been initialized? Not on document ready function, but even after that?

• Problems with maven output directory

  - by Gandalf StormCrow

  I'm using almost same POM for both my projects, they are on the same workspace but they are not related at all, they are related however because in both I use spring and jboss. Here is the pom : <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.springinaction.hello</groupId> <artifactId>spring-in-action</artifactId> <packaging>jar</packaging> <version>0.0.1-SNAPSHOT</version> <name>spring-in-action</name> <url>http://maven.apache.org</url> <properties> <jboss.ome>C:\jboss-5.1.0.GA\server\default\deploy</jboss.ome> <springversion>2.5.3</springversion> </properties> <dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring</artifactId> <version>${springversion}</version> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.14</version> <scope>provided</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-war-plugin</artifactId> <version>2.0</version> <configuration> <warName>spring-book</warName> <outputDirectory>${jboss.ome}</outputDirectory> </configuration> </plugin> </plugins> </build> </project> What I want to achieve with this POM is that I want to name my war when built spring-book.war and copy it to Jboss location I specified. Now in my first project this works it does exactly what I requested but in other it does not. I changed springversion and jboss home properties variable but everything remains the same, what can I do ? The project builds and all, everything is working perfectly just I don't want to copy everytime in my jboss dir and previously remove the old war, it takes about 20sec on each source code change its a lot

• Problems with jquery selector

  - by Gandalf StormCrow

  I have a trouble with selecting element attributes with jquery here is my HTML: <a class="myselector" rel="I need this value"></a> <div class="someClass" id="someID"> ...bunch of elements/content <input type="button" name="myInput" id="inputID" title="myInput Title" /> ...bunch of elements/content </div> ...bunch of elements/content Here I'm trying to get the rel value of myselector here is how I tried but its not working : $('#inputID').live('click',function(){ console.log($(this).closest('a.myselector').attr('rel')); }); Also tried this since all is wrapped in wrapper div : $('#inputID').live('click',function(){ console.log($(this).parent('div.wrapper').find('a.myselector').attr('rel')); }); I get undefined value in firebug in both cases, I use live because div#someID is loaded in the document its not there when page first loads. Any advice, how can I get my selector rel value?

• Java NIO Servlet to File

  - by Gandalf

  Is there a way (without buffering the whole Inputstream) to take the HttpServletRequest from a Java Servlet and write it out to a file using all NIO? Is it even worth trying? Will it be any faster reading from a normal java.io stream and writing to a java.nio Channel or do they both really need to be pure NIO to see a benefit? Thanks.

• how to modify this jquery syntax

  - by Gandalf StormCrow

  Hi all, this example below works when hover event is trigered and when its not, its working for elements already in DOM, but when element created dynamically it doesn't work, I realize I need to use jQuery live() or delegate() for this, the thing is I tried to modify it and its not producing the results as expected, here is the working code : $(".sidebar li").hover( function(){ $(this).css("background-color", "#F9F4D0"); $(this).append($('<button class="promoter" type="button" title="Active promotion"></button>')); }, function(){ $(this).css("background-color", "#F9FAFA"); $(this).children("button").remove(); } ); Here is the bit when I wanted to add live but it's not producing correct results : $(".sidebar li").live('hover', function(){ $(this).css("background-color", "#F9F4D0"); $(this).append($('<button class="promoter" type="button" title="Active promotion"></button>')); }, function(){ $(this).css("background-color", "#F9FAFA"); $(this).children("button").remove(); } ); Where did I made mistake, thank you

• Working with hibernate/DAO problems

  - by Gandalf StormCrow

  Hello everyone here is my DAO class : public class UsersDAO extends HibernateDaoSupport { private static final Log log = LogFactory.getLog(UsersDAO.class); protected void initDao() { //do nothing } public void save(User transientInstance) { log.debug("saving Users instance"); try { getHibernateTemplate().saveOrUpdate(transientInstance); log.debug("save successful"); } catch (RuntimeException re) { log.error("save failed", re); throw re; } } public void update(User transientInstance) { log.debug("updating User instance"); try { getHibernateTemplate().update(transientInstance); log.debug("update successful"); } catch (RuntimeException re) { log.error("update failed", re); throw re; } } public void delete(User persistentInstance) { log.debug("deleting Users instance"); try { getHibernateTemplate().delete(persistentInstance); log.debug("delete successful"); } catch (RuntimeException re) { log.error("delete failed", re); throw re; } } public User findById( java.lang.Integer id) { log.debug("getting Users instance with id: " + id); try { User instance = (User) getHibernateTemplate() .get("project.hibernate.Users", id); return instance; } catch (RuntimeException re) { log.error("get failed", re); throw re; } } } Now I wrote a test class(not a junit test) to test is everything working, my user has these fields in the database : userID which is 5characters long string and unique/primary key, and fields such as address, dob etc(total 15 columns in database table). Now in my test class I intanciated User added the values like : User user = new User; user.setAddress("some address"); and so I did for all 15 fields, than at the end of assigning data to User object I called in DAO to save that to database UsersDao.save(user); and save works just perfectly. My question is how do I update/delete users using the same logic? Fox example I tried this(to delete user from table users): User user = new User; user.setUserID("1s54f"); // which is unique key for users no two keys are the same UsersDao.delete(user); I wanted to delete user with this key but its obviously different can someone explain please how to do these. thank you

• Better Java method Syntax? Return early or late? [closed]

  - by Gandalf

  Duplicate: Should a function have only one return statement? and Single return or multiple return statements? Often times you might have a method that checks numerous conditions and returns a status (lets say boolean for now). Is it better to define a flag, set it during the method, and return it at the end : boolean validate(DomainObject o) { boolean valid = false; if (o.property == x) { valid = true; } else if (o.property2 == y) { valid = true; } ... return valid; } or is it better/more correct to simply return once you know the method's outcome? boolean validate(DomainObject o) { if (o.property == x) { return true; } else if (o.property2 == y) { return true; } ... return false; } Now obviously there could be try/catch blocks and all other kinds of conditions, but I think the concept is clear. Opinions?

• What is the most simple way to execute java class every 30 seconds

  - by Gandalf StormCrow

  I've been reading about java/spring/hibernate and worked trough a "dummy" examples so I told my friend to recommend something a bit harder for me, and now I'm stuck.. here is the simplest class I could think of package spring.com.practice; public class Pitcher { private String shout; public String getShout() { return shout; } public void setShout(String shout) { this.shout = shout; } public void voice() { System.out.println(getShout()); } } What is the most simple way to print out something by calling metod voice() from spring beans, and do it repeadatly every 30 seconds lets say, here is what I've got so far : <bean id="simpleTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerBean"> <property name="jobDetail" ref="jobSchedulerDetail" /> <property name="startDelay" value="0" /> <property name="repeatInterval" value="30" /> </bean> <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> <property name="schedulerName" value="pitcherScheduler" /> <property name="triggers"> <list> <ref bean="simpleTrigger" /> </list> </property> </bean> <bean id="pitcher" class="spring.com.practice.Pitcher"> <property name="shout" value="I started executing..."></property> </bean> And yes I'm trying to run this on Jboss 5, I'm building a project with maven.
