  • List to TreeSet conversion produces: "java.lang.ClassCastException: MyClass cannot be cast to java.l

    - by Chuck
    List<MyClass> myclassList = (List<MyClass>) rs.get(); TreeSet<MyClass> myclassSet = new TreeSet<MyClass>(myclassList); I don't understand why this code generates this: java.lang.ClassCastException: MyClass cannot be cast to java.lang.Comparable MyClass does not implement Comparable. I just want to use a Set to filter the unique elements of the List since my List contains unncessary duplicates.

  • Does hibernate query result always return a list?

    - by Phoenix
    Does a query execution always have to return a list ? How do I replace the code below if I am sure it will only return a single object ? @Override public List<DocInfo> findAllByDocId(String docId) { Query q = getCurrentSession().createQuery("from DocInfo item where item.id = :docId"); q.setString("docId", docId); List<DocInfo> docInfoList = q.list(); return docInfoList; }

  • org.hibernate.TransientObjectException during Criteria.list()

    - by rancidfishbreath
    I have seen posts all over the internet that talk about how to fix the TransientObjectExceptions during save/update/delete but I am having this problem when calling list on my Criteria. I have two objects A and B. A has a field named b which is of type B. In my mapping b is mapped as a many-to-one. This all runs in a larger persistence framework (the framework is kind of like Core Data) and so I don't use any cascades in my hibernate mappings since cascades are handled at a higher level. This is the interesting code surrounding my criteria: A a = new A(); B b = new B(); a.setB(b); session.save("B", b); // Actually handled by the higher level session.save("A", a); // framework, this is just for clarity // transaction committed and session closed ... // new session opened Criteria criteria = session.createCriteria(A.class); criteria.add(Restrictions.eq("b", b)); List<?> objects = criteria.list(); Basically I am looking for all objects of type A such that A.b equals a particular instance of b (I actually tried restructuring a query so that I was passing in the id of b just to make sure that b wasn't causing me problems). Here is the stack trace that occurs when I call criteria.list(): org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: B at org.hibernate.engine.ForeignKeys.getEntityIdentifierIfNotUnsaved(ForeignKeys.java:244) at org.hibernate.type.EntityType.getIdentifier(EntityType.java:449) at org.hibernate.type.ManyToOneType.nullSafeSet(ManyToOneType.java:141) at org.hibernate.loader.Loader.bindPositionalParameters(Loader.java:1769) at org.hibernate.loader.Loader.bindParameterValues(Loader.java:1740) at org.hibernate.loader.Loader.prepareQueryStatement(Loader.java:1612) at org.hibernate.loader.Loader.doQuery(Loader.java:717) at org.hibernate.loader.Loader.doQueryAndInitializeNonLazyCollections(Loader.java:270) at org.hibernate.loader.Loader.doList(Loader.java:2294) at org.hibernate.loader.Loader.listIgnoreQueryCache(Loader.java:2172) at org.hibernate.loader.Loader.list(Loader.java:2167) at org.hibernate.loader.criteria.CriteriaLoader.list(CriteriaLoader.java:119) at org.hibernate.impl.SessionImpl.list(SessionImpl.java:1706) at org.hibernate.impl.CriteriaImpl.list(CriteriaImpl.java:347) Here is my mapping: <class entity-name="A" lazy="false"> <tuplizer entity-mode="dynamic-map" class="MyTuplizer" /> <id type="long" column="id"> <generator class="native" /> </id> <many-to-one name="b" entity-name="B" column="b_id" lazy="false" /> </class> <class entity-name="B" lazy="false"> <tuplizer entity-mode="dynamic-map" class="MyTuplizer" /> <id type="long" column="id"> <generator class="native" /> </id> </class> Can anyone help me figure out why I would be getting a TransientObjectException during a fetch? Preferably I would like to find a solution that does not rely on cascades since they tend to mask problems that occur in the higher level framework.

  • Google maps api - not found address suggestion

    - by diamandiev
    Usually when you try to add a marker to an unknown/ambiguous address you just get an error from the api. It would be much nicer if i could display a list of suggestions related to the address that was not found. The Google maps site has this feature but i do not know how to do with the api. Any help would be appreciated.

  • Apache LogFormat IP Address

    - by Hanpan
    I am using the following LogFormat in my httpd.conf: LogFormat "%h %l %u %t \"%r\" %>s \"%{Referer}i\" \"%{User-Agent}i\" %a %t" combined It's working ok, but for some reason the IP address is coming out as ::1. Is there a particular reason why Apache isn't logging the users IP address? Thanks

  • Linked List Design

    - by Jim Scott
    The other day in a local .NET group I attend the following question came up: "Is it a valid interview question to ask about Linked Lists when hiring someone for a .NET development position?" Not having a computer sciense degree and being a self taught developer my response was that I did not feel it was appropriate as I in 5 years of developer with .NET had never been exposed to linked lists and did not hear any compeling reason for a use for one. However the person commented that it is a very common interview question so I decided when I left that I would do some reasearch on linked lists and see what I might be missing. I have read a number of posts on stack overflow and various google searches and decided the best way to learn about them was to write my own .NET classes to see how they worked from the inside out. Here is my class structure Single Linked List Constructor public SingleLinkedList(object value) Public Properties public bool IsTail public bool IsHead public object Value public int Index public int Count private fields not exposed to a property private SingleNode firstNode; private SingleNode lastNode; private SingleNode currentNode; Methods public void MoveToFirst() public void MoveToLast() public void Next() public void MoveTo(int index) public void Add(object value) public void InsertAt(int index, object value) public void Remove(object value) public void RemoveAt(int index) Questions I have: What are typical methods you would expect in a linked list? What is typical behaviour when adding new records? For example if I have 4 nodes and I am currently positioned in the second node and perform Add() should it be added after or before the current node? Or should it be added to the end of the list? Some of the designs I have seen explaining things seem to expose outside of the LinkedList class the Node object. In my design you simply add, get, remove values and know nothing about any node object. Should the Head and Tail be placeholder objects that are only used to define the head/tail of the list? I require my Linked List be instantiated with a value which creates the first node of the list which is essentially the head and tail of the list. Would you change that ? What should the rules be when it comes to removing nodes. Should someone be able to remove all nodes? Here is my Double Linked List Constructor public DoubleLinkedList(object value) Properties public bool IsHead public bool IsTail public object Value public int Index public int Count Private fields not exposed via property private DoubleNode currentNode; Methods public void AddFirst(object value) public void AddLast(object value) public void AddBefore(object existingValue, object value) public void AddAfter(object existingValue, object value) public void Add(int index, object value) public void Add(object value) public void Remove(int index) public void Next() public void Previous() public void MoveTo(int index)

  • detect focus on browser address bar?

    - by jedierikb
    Is there a way to detect when focus has been put onto the address-bar or the browser-search-bar? I ask because I am trying to keep focus on one element in my document, but adding a blur() listener to that element works too well in safari mac -- you can't put focus on the address-bar!

  • SSH into Ubuntu Linux on a box without a static IP address

    - by Steven Xu
    Basically, how do I do it? I'd like to connect to my home computer from work, but my internet is routed through my apartment building's network, so I don't have the static IP address I'm accustomed to having. How do I go about accessing my home computer through SSH (I'll be using Putty at work if it matters) if my home computer doesn't have a static IP address?

  • jQuery: List expands on page load

    - by Hasanah
    I've been looking for something very simple: How to make a side navigation expand with animation on page load, but all the tutorial websites I usually go to don't seem to have it. The closest I could find is this jQuery sample: http://codeblitz.wordpress.com/2009/04/15/jquery-animated-collapsible-list/ I've managed to strip down the list like so: <script type="text/javascript" src="jquery-1.3.2.min.js"></script> <script type="text/javascript"> $(function(){ $('li') .css('pointer','default') .css('list-style','none'); $('li:has(ul)') .click(function(event){ if (this == event.target) { $(this).css('list-style', (!$(this).children().is(':hidden')) ? 'none' : 'none'); $(this).children().toggle('slow'); } return false; }) .css({cursor:'pointer', 'list-style':'none'}) .children().hide(); $('li:not(:has(ul))').css({cursor:'default', 'list-style':'none'}); }); <body> <fieldset> <legend>Collapsable List Demo</legend> <ul> <li>A - F</li> <li>G - M <ul> <li>George Kent Technology Centre</li> <li>Hampshire Park</li> <li>George Kent Technology Centre</li> <li>Hampshire Park</li> </ul> </li> <li> N - R </li> <li>S - Z</li> </ul> </fieldset> My question is: Is there any way to make this list expand on page load instead of on click? I also don't need it to collapse at all; basically I need only the animating expansion. Thank you for your time and advice. :)
