  • Does MS PnP Unity Scan for Assemblies Like StructureMap?

    - by rasx
    In Using StructureMap 2.5 to scan all assemblies in a folder, we can see that StructureMap uses AssembliesFromPath() to explicitly look for types to resolve. What is the equivalent of this in Microsoft Unity? Because Unity is such a generic term, searching for documents about this online is not that easy. Update: Unity has something called an Assembly Matching Rule but its description does not communicate to me that it scans folders.

  • Why do I get Detached Entity exception when upgrading Spring Boot 1.1.4 to 1.1.5

    - by mmeany
    On updating Spring Boot from 1.1.4 to 1.1.5 a simple web application started generating detached entity exceptions. Specifically, a post authentication inteceptor that bumped number of visits was causing the problem. A quick check of loaded dependencies showed that Spring Data has been updated from 1.6.1 to 1.6.2 and a further check of the change log shows a couple of issues relating to optimistic locking, version fields and JPA issues that have been fixed. Well I am using a version field and it starts out as Null following recommendation to not set in the specification. I have produced a very simple test scenario where I get detached entity exceptions if the version field starts as null or zero. If I create an entity with version 1 however then I do not get these exceptions. Is this expected behaviour or is there still something amiss? Below is the test scenario I have for this condition. In the scenario the service layer that has been annotated @Transactional. Each test case makes multiple calls to the service layer - the tests are working with detached entities as this is the scenario I am working with in the full blown application. The test case comprises four tests: Test 1 - versionNullCausesAnExceptionOnUpdate() In this test the version field in the detached object is Null. This is how I would usually create the object prior to passing to the service. This test fails with a Detached Entity exception. I would have expected this test to pass. If there is a flaw in the test then the rest of the scenario is probably moot. Test 2 - versionZeroCausesExceptionOnUpdate() In this test I have set the version to value Long(0L). This is an edge case test and included because I found reference to Zero values being used for version field in the Spring Data change log. This test fails with a Detached Entity exception. Of interest simply because the following two tests pass leaving this as an anomaly. Test 3 - versionOneDoesNotCausesExceptionOnUpdate() In this test the version field is set to value Long(1L). Not something I would usually do, but considering the notes in the Spring Data change log I decided to give it a go. This test passes. Would not usually set the version field, but this looks like a work-around until I figure out why the first test is failing. Test 4 - versionOneDoesNotCausesExceptionWithMultipleUpdates() Encouraged by the result of test 3 I pushed the scenario a step further and perform multiple updates on the entity that started life with a version of Long(1L). This test passes. Reinforcement that this may be a useable work-around. The entity: package com.mvmlabs.domain; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.GenerationType; import javax.persistence.Id; import javax.persistence.Table; import javax.persistence.Version; @Entity @Table(name="user_details") public class User { @Id @GeneratedValue(strategy=GenerationType.AUTO) private Long id; @Version private Long version; @Column(nullable = false, unique = true) private String username; @Column(nullable = false) private Integer numberOfVisits; public Long getId() { return id; } public void setId(Long id) { this.id = id; } public Long getVersion() { return version; } public void setVersion(Long version) { this.version = version; } public Integer getNumberOfVisits() { return numberOfVisits == null ? 0 : numberOfVisits;

  • Time Saving Minutiae

    - by Dave Jarvis
    What little tricks do you use to save time when developing? For example: In JDeveloper, change the default editor to Source view from Design view for JSP files.   Tools » Preferences » File Types » Default Editors » JSP Tag File By default, JDeveloper opens JSP files in Design view, which can take 10 to 15 seconds to begin editing a file. Opening files in Source view only takes 2 seconds.

  • Convert List of one type to Array of another type using Dozer

    - by aheu
    I'm wondering how to convert a List of one type to an array of another type in Java using Dozer. The two types have all the same property names/types. For example, consider these two classes. public class A{ private String test = null; public String getTest(){ return this.test } public void setTest(String test){ this.test = test; } } public class B{ private String test = null; public String getTest(){ return this.test } public void setTest(String test){ this.test = test; } } I've tried this with no luck. List<A> listOfA = getListofAObjects(); Mapper mapper = DozerBeanMapperSingletonWrapper.getInstance(); B[] bs = mapper.map(listOfA, B[].class); I've also tried using the CollectionUtils class. CollectionUtils.convertListToArray(listOfA, B.class) Neither are working for me, can anyone tell me what I am doing wrong? The mapper.map function works fine if I create two wrapper classes, one containing a List and the other a b[]. See below: public class C{ private List<A> items = null; public List<A> getItems(){ return this.items; } public void setItems(List<A> items){ this.items = items; } } public class D{ private B[] items = null; public B[] getItems(){ return this.items; } public void setItems(B[] items){ this.items = items; } } This works oddly enough... List<A> listOfA = getListofAObjects(); C c = new C(); c.setItems(listOfA); Mapper mapper = DozerBeanMapperSingletonWrapper.getInstance(); D d = mapper.map(listOfA, D.class); B[] bs = d.getItems(); How do I do what I want to do without using the wrapper classes (C & D)? There has got to be an easier way... Thanks!

  • Generate documents thumbnails (PDF, Word, Spreadsheets, etc.) from within PHP

    - by titel
    Hello guys, I was wondering if there is there is a way to create thumbnails for different types of documents, for instance PDF documents, Word Documents, Spreadsheets, etc, not only for the images, from within PHP? If this would be to hard to accomplish, I would also be interested in a way to achieve something similar only for PDF documents instead. Thank you in advance, Constantin TOVISI

  • Is Collections.shuffle suitable for a poker algorithm?

    - by Kovu
    Hi, there is a poker-system in java, that uses Collections.shuffle() on all available cards before the cards are dealt. So a collection of 52 cards 2-9, J, Q, K, A in 4 types. After that we Collections.shuffle(). The problem is, that it seems (until now we didn't have big statistic, it's possible that we only see a lot of statistic inferences), that the algorithm is VERY unclearly. So, is Collections.shuffle() okay for a poker algorithm?

  • Can I pass a querystring that translates to a List<int> on the server?

    - by Denis Hoctor
    Hi all, I'm writing a Google Maps app that requests data from the server using jQuery's $.ajax() to send the request to my MVC Contoller. This control expects a List for the category types. What should the querystring look like for this? I've tried http://localhost:9090/mapamenities?amenityTypes=1,5 http://localhost:9090/mapamenities?amenityTypes=[1,5] with no luck. The SearchRquest attribute I'm trying to bind to is public List AmenityTypes { get; set; } Thanks Denis

  • Object Naming without Hungarian?

    - by EdOxH
    Mostly because of reading this site, I'm trying to move away from Hungarian Notation. Or I guess the improper (system) Hungarian. I can figure out a better way to name most data types, but I don't know what to do with objects. What would be a good naming convention for objects? I use objRS for recordsets now. Would I just use rs?

  • Calculate # of Rowspans and Colspans based on keys in a Multi-Array

    - by sologhost
    Ok, I have these 2 types of layouts, basically, it can be any layout really. I have decided to use tables for this, since using div tags cause undesirable results in some possible layout types. Here are 2 pics that describe the returned results of row and column: This would return the $layout array like so: $layout[0][0] $layout[0][1] $layout[1][1] In this layout type: $layout[1][0] is NOT SET, or doesn't exist. Row 1, Column 0 doesn't exist in here. So how can we use this to help us determine the rowspans...? Ok, this layout type would now return the following: $layout[0][0] $layout[0][1] $layout[1][0] $layout[2][0] $layout[2][1] $layout[3][1] Again, there are some that are NOT SET in here: $layout[1][1] $layout[3][0] Ok, I have an array called $layout that does a foreach on the row and column, but it doesn't grab the rows and columns that are NOT SET. So I created a for loop (with the correct counts of how many rows there are and how many columns there are). Here's what I got so far: // $not_set = array(); for($x = 0; $x < $cols; $x++) { $f = 0; for($p = 0; $p < $rows; $p++) { // $f = count($layout[$p]); if(!isset($layout[$p][$x])) { $f++; // It could be a rowspan or a Colspan... // We need to figure out which 1 it is! /* $not_set[] = array( 'row' => $p, 'column' => $x, ); */ } // if ($rows - count($layout[$p])) } } Ok, the $layout array has 2 keys. The first 1 is [ row ] and the 2nd key is [ column ]. Now looping through them all and determining whether it's NOT SET, tells me that either a rowspan or a colspan needs to be put into something somewhere. I'm completely lost here. Basically, I would like to have an array returned here, something like this: $spans['row'][ row # ][ column # ] = Number of rowspans for that <td> element. $spans['column'][ row # ][ column # ] = Number of colspans for that <td> element. It's either going to need a colspan or a rowspan, it will definitely never need both for the same element. Am I going about this whole thing the wrong way? Any help at all would be greatly appreciated!! I've been driving myself crazy with this for days! Pllleaase...

  • SQLAlchemy DetachedInstanceError with regular attribute (not a relation)

    - by haridsv
    I just started using SQLAlchemy and get a DetachedInstanceError and can't find much information on this anywhere. I am using the instance outside a session, so it is natural that SQLAlchemy is unable to load any relations if they are not already loaded, however, the attribute I am accessing is not a relation, in fact this object has no relations at all. I found solutions such as eager loading, but I can't apply to this because this is not a relation. I even tried "touching" this attribute before closing the session, but it still doesn't prevent the exception. What could be causing this exception for a non-relational property even after it has been successfully accessed once before? Any help in debugging this issue is appreciated. I will meanwhile try to get a reproducible stand-alone scenario and update here. Update: This is the actual exception message with a few stacks: File "/home/hari/bin/lib/python2.6/site-packages/SQLAlchemy-0.6.1-py2.6.egg/sqlalchemy/orm/attributes.py", line 159, in __get__ return self.impl.get(instance_state(instance), instance_dict(instance)) File "/home/hari/bin/lib/python2.6/site-packages/SQLAlchemy-0.6.1-py2.6.egg/sqlalchemy/orm/attributes.py", line 377, in get value = callable_(passive=passive) File "/home/hari/bin/lib/python2.6/site-packages/SQLAlchemy-0.6.1-py2.6.egg/sqlalchemy/orm/state.py", line 280, in __call__ self.manager.deferred_scalar_loader(self, toload) File "/home/hari/bin/lib/python2.6/site-packages/SQLAlchemy-0.6.1-py2.6.egg/sqlalchemy/orm/mapper.py", line 2323, in _load_scalar_attributes (state_str(state))) DetachedInstanceError: Instance <ReportingJob at 0xa41cd8c> is not bound to a Session; attribute refresh operation cannot proceed The partial model looks like this: metadata = MetaData() ModelBase = declarative_base(metadata=metadata) class ReportingJob(ModelBase): __tablename__ = 'reporting_job' job_id = Column(BigInteger, Sequence('job_id_sequence'), primary_key=True) client_id = Column(BigInteger, nullable=True) And the field client_id is what is causing this exception with a usage like the below: Query: jobs = session \ .query(ReportingJob) \ .filter(ReportingJob.job_id == job_id) \ .all() if jobs: # FIXME(Hari): Workaround for the attribute getting lazy-loaded. jobs[0].client_id return jobs[0] This is what triggers the exception later out of the session scope: msg = msg + ", client_id: %s" % job.client_id

  • Entity Framework Custom Query Function

    - by Josh
    I have an Entity Framework 4.0 Entity Object called Revision w/ Nullable DateEffectiveFrom and DateEffectiveTo dates. I was wondering if there was a short-hand way of querying an object's RevisionHistory based on a particular QueryDate date instead of having to use the following query structure: var results = EntityObject.Revisions.Where(x => (x.DateEffectiveFrom == null && x.DateEffectiveTo == null) || (x.DateEffectiveFrom == null && x.DateEffectiveTo >= QueryDate) || (x.DateEffectiveFrom <= QueryDate && x.DateEffectiveTo == null) || (x.DateEffectiveFrom <= QueryDate && x.DateEffectiveTo >= QueryDate)); I've tried creating the following boolean function in the Revision class: partial class Revision { public bool IsEffectiveOn(DateTime date) { return (x.DateEffectiveFrom == null && x.DateEffectiveTo == null) || (x.DateEffectiveFrom == null && x.DateEffectiveTo >= date) || (x.DateEffectiveFrom <= date && x.DateEffectiveTo == null) || (x.DateEffectiveFrom <= date && x.DateEffectiveTo >= date)); } ... } And then updating the query to: var results = EntityObject.Revisions.Where(x => x.IsEffectiveOn(QueryDate)); but this obviously doesn't translate to SQL. Any ideas would be much appreciated.
