  • I am getting an error with a oneToMany association when using annotations with gilead for hibernate

    - by user286630
    Hello Guys I'm using Gilead to persist my entities in my GWT project, im using hibernate annotations aswell. my problem is on my onetomany association.this is my User class that holds a reference to a list of FileLocations @Entity @Table(name = "yf_user_table") public class YFUser implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "user_id",nullable = false) private int userId; @Column(name = "username") private String username; @Column(name = "password") private String password; @Column(name = "email") private String email; @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY) @JoinColumn(name="USER_ID") private List fileLocations = new ArrayList(); This is my file location class @Entity @Table(name = "fileLocationTable") public class FileLocation implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "locationId", updatable = false, nullable = false) private int ieId; @Column (name = "location") private String location; @ManyToOne(fetch=FetchType.LAZY) @JoinColumn(name="USER_ID", nullable=false) private YFUser uploadedUser; When i persist this data in a normal desktop application, it works fine , creates the tables and i can add and store data to it. but when i try to persist the data in my gwt application i get errors i will show them lower. this is my ServiceImpl class that extends PersistentRemoteService. public class TestServiceImpl extends PersistentRemoteService implements TestService { public static final String SESSION_USER = "UserWithinSession"; public TestServiceImpl(){ HibernateUtil util = new HibernateUtil(); util.setSessionFactory(com.example.server.HibernateUtil .getSessionFactory()); PersistentBeanManager pbm = new PersistentBeanManager(); pbm.setPersistenceUtil(util); pbm.setProxyStore(new StatelessProxyStore()); setBeanManager(pbm); } @Override public String registerUser(String username, String password, String email) { Session session = com.example.server.HibernateUtil.getSessionFactory().getCurrentSession(); session.beginTransaction(); YFUser newUser = new YFUser(); newUser.setUsername(username);newUser.setPassword(password);newUser.setEmail(email); session.save(newUser); session.getTransaction().commit(); return "Thank you For registering "+ username; } this is the error that im am getting. the error goes away when i remove my onetoManyRelationship and builds my session factory when i put it in , it on the line of buildsessionfactory in hibernate Util that it throws this exception. my hibernate util class is ok also. this is the error java.lang.NoSuchMethodError: javax.persistence.OneToMany.orphanRemoval()Z Mar 24, 2010 10:03:22 PM org.hibernate.cfg.annotations.Version <clinit> INFO: Hibernate Annotations 3.5.0-Beta-4 Mar 24, 2010 10:03:22 PM org.hibernate.cfg.Environment <clinit> INFO: Hibernate 3.5.0-Beta-4 Mar 24, 2010 10:03:22 PM org.hibernate.cfg.Environment <clinit> INFO: hibernate.properties not found Mar 24, 2010 10:03:22 PM org.hibernate.cfg.Environment buildBytecodeProvider INFO: Bytecode provider name : javassist Mar 24, 2010 10:03:22 PM org.hibernate.cfg.Environment <clinit> INFO: using JDK 1.4 java.sql.Timestamp handling Mar 24, 2010 10:03:22 PM org.hibernate.annotations.common.Version <clinit> INFO: Hibernate Commons Annotations 3.2.0-SNAPSHOT Mar 24, 2010 10:03:22 PM org.hibernate.cfg.Configuration configure INFO: configuring from resource: /hibernate.cfg.xml Mar 24, 2010 10:03:22 PM org.hibernate.cfg.Configuration getConfigurationInputStream INFO: Configuration resource: /hibernate.cfg.xml Mar 24, 2010 10:03:22 PM org.hibernate.cfg.Configuration doConfigure INFO: Configured SessionFactory: null Mar 24, 2010 10:03:22 PM org.hibernate.cfg.search.HibernateSearchEventListenerRegister enableHibernateSearch INFO: Unable to find org.hibernate.search.event.FullTextIndexEventListener on the classpath.

  • Getting Perl DBD::mysql working on OS X 10.7?

    - by Bart B
    I can't seem to get Perl & MySQL to talk to each other on OS X 10.7 Lion. I did all the installs by the book, I used Oracle's PKG installer for the latest MySQL Community Server, and I installed DBI and DBD::mysql via CPAN. There were not problems at all during the install, but, when I try to USE DBD::mysql to connect to my local DB server I get the following error: install_driver(mysql) failed: Can't load '/Library/Perl/5.12/darwin-thread-multi-2level/auto/DBD/mysql/mysql.bundle' for module DBD::mysql: dlopen(/Library/Perl/5.12/darwin-thread-multi-2level/auto/DBD/mysql/mysql.bundle, 1): Library not loaded: /usr/local/mysql/lib/libmysqlclient.16.dylib Referenced from: /Library/Perl/5.12/darwin-thread-multi-2level/auto/DBD/mysql/mysql.bundle Reason: image not found at /System/Library/Perl/5.12/darwin-thread-multi-2level/DynaLoader.pm line 204. at (eval 3) line 3 Compilation failed in require at (eval 3) line 3. Perhaps a required shared library or dll isn't installed where expected After a lot of googling all I could find were suggested hacks, so I gave this one a go: http://arkoftech.wordpress.com/2011/02/10/fixing-dbdmysql-for-mysql-5-5-89-under-macos-10-6-x/ I had to update some of the paths in the instructions since on Lion it's Perl 5.12 not 5.10. After doing that I got a new error: dyld: lazy symbol binding failed: Symbol not found: _mysql_init Referenced from: /Library/Perl/5.12/darwin-thread-multi-2level/auto/DBD/mysql/mysql.bundle Expected in: flat namespace dyld: Symbol not found: _mysql_init Referenced from: /Library/Perl/5.12/darwin-thread-multi-2level/auto/DBD/mysql/mysql.bundle Expected in: flat namespace Trace/BPT trap: 5 There must be a simple way to get MySQL & Perl working on OS X? - HELP!

  • Is there a simple LDAP-to-HTTP gateway out there?

    - by larsks
    We have a local LDAP directory that provides basic contact information about our user community. We would like to integrate this into some third-party hosted services that allow us to implement widgets that run arbitrary Javascript. In order to connect Javascript to our LDAP directory, I would like to set up a simple LDAP-to-HTTP proxy that would accept HTTP GET requests, translate them into an appropriate LDAP query, and respond with directory information as JSON-encoded data. In an ideal world, something like this: GET /[email protected] Would get me something like this: { "cn": "Bob Person", "title": "System Administrator", "sn": "Person", "mail": "[email protected]", "telepehoneNumber": "617-555-1212", "givenName": "Bob" } (And this obviously assumes that the web application has locally configured information about what base DN to use, how to authenticate, etc). I guess I could write one...but surely something like this already exists? UPDATE The consensus seems to be that there isn't a pre-existing solution out there and that I should just get off my lazy derriere and write one. So I did, and it's here. It's not especially pretty, but it works for my prototyping and I figure maybe someone else will find it useful someday.

  • Windows 7 disk backup and clone for deployment to multiple systems

    - by gregmac
    I'm in the process of deploying some new PCs (there's only 8), all identical hardware. What I'd like to do is install Windows 7 (64bit), join to domain etc, install a bunch of other software, and then clone that drive to multiple other machines. I'd also like to be able to use it as a backup image, so the machine can be restored back to that image at some future date. I understand this involves at least sysprep, but I am confused after reading some tutorials that talk about using Windows Automated Installation Kit, or hacks with the registry and custom-build batch files. This process seems overly complex to me: I did something similar 10+ years ago, and and don't remember it being this bad. Surely things have improved in a decade? There's also some products that involve having network servers running deployment software, network boot, etc etc.. this is way more than I want to set up. My systems are all identical hardware. Is there a simplified way to clone PCs? Preferably (since I'm a lazy developer, and not an IT admin) I'd like to find some off-the-shelf product that I can run after I get the machine setup, that will spit out a bootable DVD I can run on all the other systems, which will boot up, ask for a computer name, join it to the domain, and that's it. Does such as product exist?

  • Storage model for various user setting and attributes in database?

    - by dvd
    I'm currently trying to upgrade a user management system for one web application. This web application is used to provide remote access to various networking equipment for educational purposes. All equipment is assigned to various pods, which users can book for periods of time. The current system is very simple - just 2 user types: administrators and students. All their security and other attributes are mostly hardcoded. I want to change this to something like the following model: user <-- (1..n)profile <--- (1..n) attributes. I.e. user can be assigned several profiles and each profile can have multiple attributes. At runtime all profiles and attributes are merged into single active profile. Some examples of attributes i'm planning to implement: EXPIRATION_DATE - single value, value type: date, specifies when user account will expire; ACCESS_POD - single value, value type: ref to object of Pod class, specifies which pod the user is allowed to book, user profile can have multiple such attributes with different values; TIME_QUOTA - single value, value type: integer, specifies maximum length of time for which student can reserve equipment. CREDIT_CHARGING - multi valued, specifies how much credits will be assigned to user over period of time. (Reservation of devices will cost credits, which will regenerate over time); Security permissions and user preferences can end up as profile or user attributes too: i.e CAN_CREATE_USERS, CAN_POST_NEWS, CAN_EDIT_DEVICES, FONT_SIZE, etc.. This way i could have, for example: students of course A will have profiles STUDENT (with basic attributes) and PROFILE A (wich grants acces to pod A). Students of course B will have profiles: STUDENT, PROFILE B(wich grants to pod B and have increased time quotas). I'm using Spring and Hibernate frameworks for this application and MySQL for database. For this web application i would like to stay within boundaries of these tools. The problem is, that i can't figure out how to best represent all these attributes in database. I also want to create some kind of unified way of retrieveing these attributes and their values. Here is the model i've come up with. Base classes. public abstract class Attribute{ private Long id; Attribute() {} abstract public String getName(); public Long getId() {return id; } void setId(Long id) {this.id = id;} } public abstract class SimpleAttribute extends Attribute{ public abstract Serializable getValue(); abstract void setValue(Serializable s); @Override public boolean equals(Object obj) { ... } @Override public int hashCode() { ... } } Simple attributes can have only one value of any type (including object and enum). Here are more specific attributes: public abstract class IntAttribute extends SimpleAttribute { private Integer value; public Integer getValue() { return value; } void setValue(Integer value) { this.value = value;} void setValue(Serializable s) { setValue((Integer)s); } } public class MaxOrdersAttribute extends IntAttribute { public String getName() { return "Maximum outstanding orders"; } } public final class CreditRateAttribute extends IntAttribute { public String getName() { return "Credit Regeneration Rate"; } } All attributes stored stored using Hibenate variant "table per class hierarchy". Mapping: <class name="ru.mirea.rea.model.abac.Attribute" table="ATTRIBUTES" abstract="true" > <id name="id" column="id"> <generator class="increment" /> </id> <discriminator column="attributeType" type="string"/> <subclass name="ru.mirea.rea.model.abac.SimpleAttribute" abstract="true"> <subclass name="ru.mirea.rea.model.abac.IntAttribute" abstract="true" > <property name="value" column="intVal" type="integer"/> <subclass name="ru.mirea.rea.model.abac.CreditRateAttribute" discriminator-value="CreditRate" /> <subclass name="ru.mirea.rea.model.abac.MaxOrdersAttribute" discriminator-value="MaxOrders" /> </subclass> <subclass name="ru.mirea.rea.model.abac.DateAttribute" abstract="true" > <property name="value" column="dateVal" type="timestamp"/> <subclass name="ru.mirea.rea.model.abac.ExpirationDateAttribute" discriminator-value="ExpirationDate" /> </subclass> <subclass name="ru.mirea.rea.model.abac.PodAttribute" abstract="true" > <many-to-one name="value" column="podVal" class="ru.mirea.rea.model.pods.Pod"/> <subclass name="ru.mirea.rea.model.abac.PodAccessAttribute" discriminator-value="PodAccess" lazy="false"/> </subclass> <subclass name="ru.mirea.rea.model.abac.SecurityPermissionAttribute" discriminator-value="SecurityPermission" lazy="false"> <property name="value" column="spVal" type="ru.mirea.rea.db.hibernate.customTypes.SecurityPermissionType"/> </subclass> </subclass> </class> SecurityPermissionAttribute uses enumeration of various permissions as it's value. Several types of attributes imlement GrantedAuthority interface and can be used with Spring Security for authentication and authorization. Attributes can be created like this: public final class AttributeManager { public <T extends SimpleAttribute> T createSimpleAttribute(Class<T> c, Serializable value) { Session session = HibernateUtil.getCurrentSession(); T att = null; ... att = c.newInstance(); att.setValue(value); session.save(att); session.flush(); ... return att; } public <T extends SimpleAttribute> List<T> findSimpleAttributes(Class<T> c) { List<T> result = new ArrayList<T>(); Session session = HibernateUtil.getCurrentSession(); List<T> temp = session.createCriteria(c).list(); result.addAll(temp); return result; } } And retrieved through User Profiles to which they are assigned. I do not expect that there would be very large amount of rows in the ATTRIBUTES table, but are there any serious drawbacks of such design?

Let me make this more clear: a MVC page uses the spring part trying to load a lazy-init service which constructor wants a connection string through a static property like this: <object id="promotionRepos" type="ECommerce.Data.AdoNet.Promotions.PromotionRepos, ECommerce.Data.AdoNet" lazy-init="true"> <constructor-arg name="provider"> <null /> </constructor-arg> <constructor-arg name="connStr"> <object type="ECommerce.ERP.DAL.DBConn, ECommerce.ERP.DAL" factory-method="get_ConnString" /> </constructor-arg> <property name="RefreshInterval" value="00:00:10" /> </object> the timeout part is some what irrelevent to all others. see this in the first exception: Shopping_Shopping.Page_Load(Object sender, EventArgs e) +10 it's another page at all. And also, ECommerce.PMethod.Sql.SqlConns.Open() uses its own connection string, not the one loaded by spring, it's different module from diffrent team. And I am sure the connection string is correct. And, this ysod cames up randomly. Sometimes nothing is wrong, and sometimes, it appears. I thought there could be something wrong with my database or the network/firewall, I will check it later, but now I want understand this tricky stack trace.

  • Set proper rights for sshfs mountpoint so it can be shared with samba

    - by CS01
    I have a domain hoster that provides access via SSH. My platforms are: Gentoo 2.6.36-r5 Windows (XP/Vista/7) I work on my Windows, I use Gentoo to do all the magic Windows can't do. Therefore I use sshfs to mount the remote public directory for my domain to /mnt/mydomain.com. Authentication is done via keys, so lazy me don't have to type in my password every now and then. Since I do my coding on Windows, and I don't want to upload/download the changed files all the time, I want to access this /mnt/mydomain.com via a samba share. So I shared /mnt in samba, all mounts except mydomain.com is listed on my Windows Explorer. My theories are: sshfs does not set the mountpoint uid/gid to something that samba expects samba does not know that it has to include the uid/gid that /mnt/mydomain.com has been set. All above is wrong, and I don't know. Here are configs and output from console, need anything else just let me know.

  • Windows file association for README, INSTALL, LICENSE and the like [closed]

    - by Lumi
    Possible Duplicate: How to set the default program for opening files without an extension in Windows? Many files originating in the UNIX world come without file extension. Popular examples include README, INSTALL, LICENSE. We know for a fact that these are text files. It is therefore a bit disappointing not to be able to just double-click them open in Explorer and see them in Notepad (actually, Notepad2 because of the UNIX line endings which silly Microsoft Notepad doesn't render correctly). Does anyone know of a way to create a file association for, say, README files without extension? This could then be replicated to cover the most frequently occurring file types, and then double-clicking them open would work. Update (Sort of in response to all your comments.) Thanks, folks, your comments and answers have helped me. @Indrek, yes, I was under the assumption that you could somehow create an association for just README or Makefile, and couldn't do so for files without extension. Turns out the contrary is true, and yes, that is a workaround that neatly solves the issue. Ultimately, I just want to be able to double-click to open a README or Makefile, that's all. @Sampo, the SendMe trick is also useful, although usability is not as great as a straight double-click. (I'm really lazy sometimes.) Turns out the following trick using ftype and ftype from an Administrator prompt does the double-click enabling job: assoc .=no_ext ftype no_ext=%SystemRoot%\system32\NOTEPAD.EXE %1 :: You can see it created some entries in the registry: reg query hkcr\no_ext /s reg query hkcr\. /s

  • /usr/bin/install hangs, apparently due to SELinux

    - by Cooper
    I'm trying to use the GNU coreutils install utility, however it is hanging: /usr/bin/install -v test_file test_dir/ `test_file' -> `test_dir/test_file I see the same behavior whether I run as a normal user, or root/sudo. I ran an strace -f, and this is the end of the output: ... read(4, "<username>\t-d\tsystem_u:object_r:ho"..., 4096) = 2197 <0.000012> brk(0x6e3b1000) = 0x6e3b1000 <0.000009> mmap(NULL, 29138944, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2abd831ae000 <0.000014> munmap(0x2abd815dd000, 29138944) = 0 <0.003466> The read() is reading from /etc/selinux/targeted/contexts/files/file_contexts.homedirs, apparently successfully. It appears that the process is hanging right after the munmap, but continues to eat 100% CPU. My two questions are: 1) Any good way to see what is going on with the process? I'm currently too lazy to compile a debug version of install I can run gdb on - but a strong suggestion in an answer here may motivate me to do so if needed. 2) Any idea what the SELinux issue could be? I'm not too familiar with SELinux. Additional info of possible relevance: # ls -Z drwxr-xr-x my_user 7001 user_u:object_r:user_home_t test_dir -rw-r--r-- my_user 7001 user_u:object_r:user_home_t test_file # id ... context=user_u:system_r:unconfined_t # uname -a Linux hostname 2.6.18-238.1.1.el5 #1 SMP Tue Jan 4 13:32:19 EST 2011 x86_64 x86_64 x86_64 GNU/Linux I am suspicious that SELinux + Quest Authentication Services (QAS) is causing the issue. QAS is generally well behaved, but it did cause the /etc/selinux/targeted/contexts/files/file_contexts.homedirs to get quite large (~18k users, @23 lines per user) Update: install -v -Z user_u:object_r:user_home_t file dir/ seems to work. Can anyone suggest why, given that SELinux is in permissive mode (see comments).

  • Windows-to-linux: Putty with SSH and private/public key pair

    - by Johnny Kauffman
    I spent about 3 hours trying to figure out how to connect to a linux box from my windows machine using putty without having to send the password. This is connecting to an Ubuntu server that is using OpenSSH. The private key is SSH-2 RSA, 1024 bits. I am connecting using SSH2. I have run into the more common problems already: Putty generated the public key in the "wrong format". I have corrected this (as seen on this blog post). However, since I am not yet connected, I cannot absolutely confirm that this file is in the correct format. The key is all on a single line now, and I have tried adding/removing line breaks at the end of the file. I've also tried the public file doctoring process a few times to ensure that I haven't flubbed up the manual conversion. Even so, I have no way to verify accuracy here. The permissions were at once point wrong as well, specifically meaning that the file had too many permissions. I had to solve this too and I know it got past this because I no longer see a related error in /var/log/auth.log. I've tried both authorized_keys and authorized_keys2 in case the server has an old version of OpenSSH, but this changed nothing. I do have access as a user. After this keyfile stuff fails, I can enter my password instead The only remaining nibble of information I have is that it claims I have the alleged password wrong: sshd[22288]: Failed password for zzzzzzz from zz.zz.zz.zz port 53620 ssh2 Even so, as far as I can tell, this is just a lazy try/catch somewhere, since I don't think there's a password involved at all. I see nothing else in any of the /var/log files of use. What else could be wrong?

  • Liked Arch Linux - but I am still not sure if its the right distro for me...

    - by BlackAndGold
    As the title says... I used Arch Linux for a while and liked it a lot: leightweight, sleek, fast and well documented with a great community. However I had to format my hd and for the sake of being too lazy to reinstall arch, I used windows 7 exclusively for a while. Now I want to get back to linux again (still dual boot), mainly for web development purposes and using handy tools such as rsync ect. Again, I liked Arch, but there is too much tweeking, too much reading up and too much figuring out what to do as well es some bad suprises especially when you need them the least and when just quickly want to get some work done. I kind of would like to have a little more "out of the box" distro that is still fast and somewhat leighweight and of course reliable. I actually considered Ubuntu, which I am not too big of a fan of, but I will still give the minimal install a shot. However other distros seem interesting as well, such as crunchbang and mint debian ecpecially. My question, hoping this isn't too boring for many you, what is the right distro for me?

  • How to migrate WinXP from failing old HD to new one

    - by Péter Török
    Following this issue, we have all our important data backed up now. I also bought and installed a new replacement hard disk (WD 160GB PATA) as secondary (slave) drive. I created two primary NTFS partitions on it: a 40 GB system partition, and a 110GB data partition. In theory I could start reinstalling WinXP from scratch on the new system partition, then copying over all user data from the old drive to the new data partition. Once this is done, I could even throw away the old drive, or keep it just to see what happens. (Note: I don't want to clone the whole drive as it contains a dual boot setup with an old Linux installation which I don't need anymore, and anyway, a fresh reinstall would do WinXP good to get rid of many years' clutter.) However, I am lazy :-) The old HD is still functioning, the problem has not manifested again since. So I feel there is no need to hurry with a complete OS reinstall. What I don't know though is whether I will be able to install WinXP on the new system partition at a later stage without affecting the contents of the data partition on the same drive. If this is possible, I can just move over all our data to the new data partition to have it safe, then continue running WinXP from the old drive as long as it works. Does anyone see any problems/risks with this plan?

  • Is there a faster way to change default apps associated with file types on OS X?

    - by Lri
    Is there anything more convenient than using RCDefaultApp or Magic Launch, or just repeatedly pressing the Change All buttons in Finder's information panels? I thought about writing a shell script that would modify the CFBundleDocumentTypes arrays in Info.plist files. But each app has multiple keys (sometimes an icon) that would need to be changed. lsregister can't be used to make specific modifications to the Launch Services database. $ `locate lsregister` -h lsregister: [OPTIONS] [ <path>... ] [ -apps <domain>[,domain]... ] [ -libs <domain>[,domain]... ] [ -all <domain>[,domain]... ] Paths are searched for applications to register with the Launch Service database. Valid domains are "system", "local", "network" and "user". Domains can also be specified using only the first letter. -kill Reset the Launch Services database before doing anything else -seed If database isn't seeded, scan default locations for applications and libraries to register -lint Print information about plist errors while registering bundles -convert Register apps found in older LS database files -lazy n Sleep for n seconds before registering/scanning -r Recursive directory scan, do not recurse into packages or invisible directories -R Recursive directory scan, descending into packages and invisible directories -f force-update registration even if mod date is unchanged -u unregister instead of register -v Display progress information -dump Display full database contents after registration -h Display this help

  • Productive Writing Software

    - by Nick Retallack
    What do you guys use to write a personal journal, notes, and reference information that you want to group and search through later? I'm not one of those crazy people who likes to share their journal with the world. Some things I like to keep to myself. It's quite nice to have a reference. Preferences for cross-platform stuff (windows, mac, linux) Some Background For Windows, there's a program called Yeah Write, which really changed my expectations about how easy it should be to start writing something. You don't open or close files -- just click an empty slot and start writing, or click a filled slot to work on another file. And you can organize things into categories by creating tabs. Now that I carry a Macbook, I've just been using TextEdit. I like it because I can't lose my work when my computer crashes: it auto-saves everything and restores it when I launch TextEdit again. But I make a mess, leave thirty open files, and save everything to one directory with no tags for easy grouping. Saving files and selecting the directory they should be in is too clunky to do in the middle of a meeting. And organizing files into folders in the Finder is a pain, since there's no tree view like on Windows. Sure, I'm lazy, but I miss Yeah Write. I'm not going to get a windows laptop just to use it though. Since the laptop I take my notes on is a mac, I'm gonna be biased toward mac solutions.

  • XFS: No space left on device

  • ORACLE RIGHTNOW DYNAMIC AGENT DESKTOP CLOUD SERVICE - Putting the Dynamite into Dynamic Agent Desktop

    - by Andreea Vaduva
    Untitled Document There’s a mountain of evidence to prove that a great contact centre experience results in happy, profitable and loyal customers. The very best Contact Centres are those with high first contact resolution, customer satisfaction and agent productivity. But how many companies really believe they are the best? And how many believe that they can be? We know that with the right tools, companies can aspire to greatness – and achieve it. Core to this is ensuring their agents have the best tools that give them the right information at the right time, so they can focus on the customer and provide a personalised, professional and efficient service. Today there are multiple channels through which customers can communicate with you; phone, web, chat, social to name a few but regardless of how they communicate, customers expect a seamless, quality experience. Most contact centre agents need to switch between lots of different systems to locate the right information. This hampers their productivity, frustrates both the agent and the customer and increases call handling times. With this in mind, Oracle RightNow has designed and refined a suite of add-ins to optimize the Agent Desktop. Each is designed to simplify and adapt the agent experience for any given situation and unify the customer experience across your media channels. Let’s take a brief look at some of the most useful tools available and see how they make a difference. Contextual Workspaces: The screen where agents do their job. Agents don’t want to be slowed down by busy screens, scrolling through endless tabs or links to find what they’re looking for. They want quick, accurate and easy. Contextual Workspaces are fully configurable and through workspace rules apply if, then, else logic to display only the information the agent needs for the issue at hand . Assigned at the Profile level, different levels of agent, from a novice to the most experienced, get a screen that is relevant to their role and responsibilities and ensures their job is done quickly and efficiently the first time round. Agent Scripting: Sometimes, agents need to deliver difficult or sensitive messages while maximising the opportunity to cross-sell and up-sell. After all, contact centres are now increasingly viewed as revenue generators. Containing sophisticated branching logic, scripting helps agents to capture the right level of information and guides the agent step by step, ensuring no mistakes, inconsistencies or missed opportunities. Guided Assistance: This is typically used to solve common troubleshooting issues, displaying a series of question and answer sets in a decision-tree structure. This means agents avoid having to bookmark favourites or rely on written notes. Agents find particular value in these guides - to quickly craft chat and email responses. What’s more, by publishing guides in answers on support pages customers, can resolve issues themselves, without needing to contact your agents. And b ecause it can also accelerate agent ramp-up time, it ensures that even novice agents can solve customer problems like an expert. Desktop Workflow: Take a step back and look at the full customer interaction of your agents. It probably spans multiple systems and multiple tasks. With Desktop Workflows you control the design workflows that span the full customer interaction from start to finish. As sequences of decisions and actions, workflows are unique in that they can create or modify different records and provide automation behind the scenes. This means your agents can save time and provide better quality of service by having the tools they need and the relevant information as required. And doing this boosts satisfaction among your customers, your agents and you – so win, win, win! I have highlighted above some of the tools which can be used to optimise the desktop; however, this is by no means an exhaustive list. In approaching your design, it’s important to understand why and how your customers contact you in the first place. Once you have this list of “whys” and “hows”, you can design effective policies and procedures to handle each category of problem, and then implement the right agent desktop user interface to support them. This will avoid duplication and wasted effort. Five Top Tips to take away: Start by working out “why” and “how” customers are contacting you. Implement a clean and relevant agent desktop to support your agents. If your workspaces are getting complicated consider using Desktop Workflow to streamline the interaction. Enhance your Knowledgebase with Guides. Agents can access them proactively and can be published on your web pages for customers to help themselves. Script any complex, critical or sensitive interactions to ensure consistency and accuracy. Desktop optimization is an ongoing process so continue to monitor and incorporate feedback from your agents and your customers to keep your Contact Centre successful.   Want to learn more?

  • Changing the sequencing strategy for File/Ftp Adapter

    - by [email protected]
    The File/Ftp Adapter allows the user to configure the outbound write to use a sequence number. For example, if I choose address-data_%SEQ%.txt as the FileNamingConvention, then all my files would be generated as address-data_1.txt, address-data_2.txt,...and so on. But, where does this sequence number come from? The answer lies in the "control directory" for the particular adapter project(or scenario). In general, for every project that use the File or Ftp Adapter, a unique directory is created for book keeping purposes. And since this control directory is required to be unique, the adapter uses a digest to make sure that no two control directories are the same. For example, for my FlatStructure sample, the control information for my project would go under FMW_HOME/user_projects/domains/soainfra/fileftp/controlFiles/[DIGEST]/outbound where the value of DIGEST would differ from one project to another. If you look under this directory, you will see a file control_ob.properties and this is where the sequence number is maintained. Please note that the sequence number is maintained in binary form and you hence you might need a hex editor to view its content. You will also see another zero byte file, SEQ_nnn, but, ignore that for now. We'll get to it some other time. For now, please remember that this extra file is maintained as a backup. One of the challenges faced by the adapter runtime is to guard all writes to the control files so no two threads inadverently try to update them at the same time. And, it does so with the help of a "Mutex". For now, please remember that the mutex comes in different flavors: In-memory DB-based Coherence-based User-defined Again, we will talk about these mutexes some other time. Please note that there might be scenarios, particularly under heavy load, where the mutex might become a bottleneck. The adapter, however,  allows you to change the configuration so that the adapter sequence value comes from a database sequence or a stored procedure and in such situation, the mutex is acually by-passed and thereby resulting in better throughputs. In later releases, the behavior of the adapter would be defaulted to use a db-sequence.  The simplest way to achieve this is by switching your JNDI for the outbound JCA file to use "eis/HAFileAdapter" as shown   But, what does this do? Internally, the adapter runtime creates a sequence on the oracle database. For example, if you do a "select * from user_sequences" in your soa-infra schema, you will see a new sequence being created with name as SEQ_<GUID>__ where the GUID will differ from one project to another. However, if you want to use your own sequence, then it would require you to add a new property to your JCA file called SequenceName as shown below. Please note that you will need to create this sequence on your soainfra schema beforehand.     But, what if we use DB2 or MSSQL Server as the dehydration support? DB2 supports sequences natively but MSSQL Server does not. So, the adapter runtime uses a natively generated sequence for DB2, but, for MSSQL server, the adapter relies on a stored procedure that ships with the product. If you wish to achieve the same result for SOA Suite running DB2 as the dehydration store, simply change your connection factory JNDI name in the JCA file to eis/HAFileAdapterDB2 and for MSSQL, please use eis/HAFileAdapterMSSQL. And, if you wish to use a stored procedure other than the one that ships with the product, you will need to rely on binding properties to override the adapter behavior. Particularly, you will need to instruct the adapter that you wish to use a stored procedure as shown:       Please note that if you're using the File/Ftp Adapter in Append mode, then the adapter runtime degrades the mutex to use pessimistic locks as we don't want writers from different nodes to append to the same file at the same time.

  • The Collatz Sequence problem

    - by Gandalf StormCrow
    I'm trying to solve this problem, its not a homework question, its just code I'm submitting to uva.onlinejudge.org so I can learn better java trough examples. Here is the problem sample input : 3 100 34 100 75 250 27 2147483647 101 304 101 303 -1 -1 Here is simple output : Case 1: A = 3, limit = 100, number of terms = 8 Case 2: A = 34, limit = 100, number of terms = 14 Case 3: A = 75, limit = 250, number of terms = 3 Case 4: A = 27, limit = 2147483647, number of terms = 112 Case 5: A = 101, limit = 304, number of terms = 26 Case 6: A = 101, limit = 303, number of terms = 1 The thing is this has to execute within 3sec time interval otherwise your question won't be accepted as solution, here is with what I've come up so far, its working as it should just the execution time is not within 3 seconds, here is code : import java.util.Scanner; class Main { public static void main(String[] args) { Scanner stdin = new Scanner(System.in); int start; int limit; int terms; int a = 0; while (stdin.hasNext()) { start = stdin.nextInt(); limit = stdin.nextInt(); if (start > 0) { terms = getLength(start, limit); a++; } else { break; } System.out.println("Case "+a+": A = "+start+", limit = "+limit+", number of terms = "+terms); } } public static int getLength(int x, int y) { int length = 1; while (x != 1) { if (x <= y) { if ( x % 2 == 0) { x = x / 2; length++; }else{ x = x * 3 + 1; length++; } } else { length--; break; } } return length; } } And yes here is how its meant to be solved : An algorithm given by Lothar Collatz produces sequences of integers, and is described as follows: Step 1: Choose an arbitrary positive integer A as the first item in the sequence. Step 2: If A = 1 then stop. Step 3: If A is even, then replace A by A / 2 and go to step 2. Step 4: If A is odd, then replace A by 3 * A + 1 and go to step 2. And yes my question is how can I make it work inside 3 seconds time interval?

  • Most efficient algorithm for merging sorted IEnumerable<T>

    - by franck
    Hello, I have several huge sorted enumerable sequences that I want to merge. Theses lists are manipulated as IEnumerable but are already sorted. Since input lists are sorted, it should be possible to merge them in one trip, without re-sorting anything. I would like to keep the defered execution behavior. I tried to write a naive algorithm which do that (see below). However, it looks pretty ugly and I'm sure it can be optimized. It may exist a more academical algorithm... IEnumerable<T> MergeOrderedLists<T, TOrder>(IEnumerable<IEnumerable<T>> orderedlists, Func<T, TOrder> orderBy) { var enumerators = orderedlists.ToDictionary(l => l.GetEnumerator(), l => default(T)); IEnumerator<T> tag = null; var firstRun = true; while (true) { var toRemove = new List<IEnumerator<T>>(); var toAdd = new List<KeyValuePair<IEnumerator<T>, T>>(); foreach (var pair in enumerators.Where(pair => firstRun || tag == pair.Key)) { if (pair.Key.MoveNext()) toAdd.Add(pair); else toRemove.Add(pair.Key); } foreach (var enumerator in toRemove) enumerators.Remove(enumerator); foreach (var pair in toAdd) enumerators[pair.Key] = pair.Key.Current; if (enumerators.Count == 0) yield break; var min = enumerators.OrderBy(t => orderBy(t.Value)).FirstOrDefault(); tag = min.Key; yield return min.Value; firstRun = false; } } The method can be used like that: // Person lists are already sorted by age MergeOrderedLists(orderedList, p => p.Age); assuming the following Person class exists somewhere: public class Person { public int Age { get; set; } } Duplicates should be conserved, we don't care about their order in the new sequence. Do you see any obvious optimization I could use?

  • Exception in thread "main" java.lang.StackOverflowError

    - by Ray.R.Chua
    I have a piece of code and I could not figure out why it is giving me Exception in thread "main" java.lang.StackOverflowError. This is the question: Given a positive integer n, prints out the sum of the lengths of the Syracuse sequence starting in the range of 1 to n inclusive. So, for example, the call: lengths(3) will return the the combined length of the sequences: 1 2 1 3 10 5 16 8 4 2 1 which is the value: 11. lengths must throw an IllegalArgumentException if its input value is less than one. My Code: import java.util.HashMap; public class Test { HashMap<Integer,Integer> syraSumHashTable = new HashMap<Integer,Integer>(); public Test(){ } public int lengths(int n)throws IllegalArgumentException{ int sum =0; if(n < 1){ throw new IllegalArgumentException("Error!! Invalid Input!"); } else{ for(int i =1; i<=n;i++){ if(syraSumHashTable.get(i)==null) { syraSumHashTable.put(i, printSyra(i,1)); sum += (Integer)syraSumHashTable.get(i); } else{ sum += (Integer)syraSumHashTable.get(i); } } return sum; } } private int printSyra(int num, int count){ int n = num; if(n == 1){ return count; } else{ if(n%2==0){ return printSyra(n/2, ++count); } else{ return printSyra((n*3)+1, ++count) ; } } } } Driver code: public static void main(String[] args) { // TODO Auto-generated method stub Test s1 = new Test(); System.out.println(s1.lengths(90090249)); //System.out.println(s1.lengths(5)); } . I know the problem lies with the recursion. The error does not occur if the input is a small value, example: 5. But when the number is huge, like 90090249, I got the Exception in thread "main" java.lang.StackOverflowError. Thanks all for your help. :) I almost forgot the error msg: Exception in thread "main" java.lang.StackOverflowError at Test.printSyra(Test.java:60) at Test.printSyra(Test.java:65) at Test.printSyra(Test.java:60) at Test.printSyra(Test.java:65) at Test.printSyra(Test.java:60) at Test.printSyra(Test.java:60) at Test.printSyra(Test.java:60) at Test.printSyra(Test.java:60)

  • Favorite Visual Studio keyboard remappings?

    - by hoytster
    Stack Overflow has covered favorite short-cuts and add-ins, optimizations and preferences -- great topics all. If this one has been covered, I can't find it -- so thanks in advance for the link. What are your favorite Visual Studio keyboard remappings? Mine are motivated by the fact that I'm a touch-typist. Mouse, function keys, arrow keys, Home, End -- bleh. These are commands I do all day every day, so I've remapped them to sequences I can execute without moving my hands from the home row. The command that is remapped in Tools = Customize = [Keyboard] is shown in parentheses. I'm 100% positive that there are better remappings than these, so please post yours! Please include the command; oft times, figuring it out is a challenge. -- Hoytster Running the app and operating the debugger Ctrl+Q + Ctrl+R Run the application, in debug mode (Debug.Start) Ctrl+Q + Ctrl+Q Quit (stop) the application (Debug.StopDebugging) Ctrl+T Toggle a breakpoint at the current line (Debug.ToggleBreakpoint) Ctrl+K + Ctrl+I Step Into the method (Debug.StepInto) Ctrl+K + Ctrl+O Step Out of the method (Debug.StepOut) Ctrl+N Step over the method to the Next statement (Debug.StepOver) Ctrl+K + Ctrl+C Run the code, stopping at the Cursor position (Debug.RunToCursor) Ctrl+K + Ctrl+E Set then next statement to Execute (Debug.SetNextStatement) Navigating the code Ctrl+S Move a character LEFT (Edit.CharLeft) Ctrl+D Move a character RIGHT (Edit.CharRight) Ctrl+Q + Ctrl+S Move to the LEFT END of the current line (Edit.LineStart) Ctrl+Q + Ctrl+D Move to the RIGHT END of the current line (Edit.LineEnd) Ctrl+E Move a line UP (Edit.LineUp) Ctrl+X Move a line DOWN (Edit.LineDown) Ctrl+K + Ctrl+K Toggle (add or remove) bookmark (Edit.ToggleBookmark) Ctrl+K + Ctrl+N Move to the NEXT bookmark (Edit.NextBookmark) Ctrl+K + Ctrl+P Move to the PREVIOUS bookmark (Edit.PreviousBookmark) Ctrl+Q + Ctrl+W Save all modified Windows (File.SaveAll) Ctrl+L Find the NEXT instance of the search string (Edit.FindNext) Ctrl+K + Ctrl+L Find the PREVIOUS instance of the search string (Edit.FindPrevious) Ctrl+Q + Ctrl+L Drop down the list of open files (Window.ShowEzMDIFileList) The last sequence is like clicking the downward-facing triangle in the upper-right corner of the code editor window.

  • Delphi / MySql : Problems escaping strings

    - by mawg
    N00b here, having problems escaping strings. I used the QuotedStr() function - shouldn't that be enough. Unfortunately, the string that I am trying to quote is rather messy, but I will post it here in case anyone wants to paste it into WinMerge or KDiff3, etc. I am trying to store an entire Delphi form into the database, rather than into a .DFM file. It has only one field, a TEdit edit box. The debugger shows the form as text as 'object Form1: TScriptForm'#$D#$A' Left = 0'#$D#$A' Top = 0'#$D#$A' Align = alClient'#$D#$A' BorderStyle = bsNone'#$D#$A' ClientHeight = 517'#$D#$A' ClientWidth = 993'#$D#$A' Color = clBtnFace'#$D#$A' Font.Charset = DEFAULT_CHARSET'#$D#$A' Font.Color = clWindowText'#$D#$A' Font.Height = -11'#$D#$A' Font.Name = 'MS Sans Serif''#$D#$A' Font.Style = []'#$D#$A' OldCreateOrder = False'#$D#$A' SaveProps.Strings = ('#$D#$A' 'Visible=False')'#$D#$A' PixelsPerInch = 96'#$D#$A' TextHeight = 13'#$D#$A' object Edit1: TEdit'#$D#$A' Left = 192'#$D#$A' Top = 64'#$D#$A' Width = 121'#$D#$A' Height = 21'#$D#$A' TabOrder = 8'#$D#$A' end'#$D#$A'end'#$D#$A before calling QuotedStr() and ''object Form1: TScriptForm'#$D#$A' Left = 0'#$D#$A' Top = 0'#$D#$A' Align = alClient'#$D#$A' BorderStyle = bsNone'#$D#$A' ClientHeight = 517'#$D#$A' ClientWidth = 993'#$D#$A' Color = clBtnFace'#$D#$A' Font.Charset = DEFAULT_CHARSET'#$D#$A' Font.Color = clWindowText'#$D#$A' Font.Height = -11'#$D#$A' Font.Name = ''MS Sans Serif'''#$D#$A' Font.Style = []'#$D#$A' OldCreateOrder = False'#$D#$A' SaveProps.Strings = ('#$D#$A' ''Visible=False'')'#$D#$A' PixelsPerInch = 96'#$D#$A' TextHeight = 13'#$D#$A' object Edit1: TEdit'#$D#$A' Left = 192'#$D#$A' Top = 64'#$D#$A' Width = 121'#$D#$A' Height = 21'#$D#$A' TabOrder = 8'#$D#$A' end'#$D#$A'end'#$D#$A''' afterwards.

What am I doing that is obviously, glaringly wrong?
