Using Fast Connect Failover (FCF) functionality of Oracle10g in Spring

ketakid21 — Tue, 09 Feb 2010 06:50:24 GMT

Hello Experts,

I want to use fastConnectionFailover functionality of Oracle10g in my project. The old configuration of project is using BasicDataSource, but to use fastConnectionFailover functionaliy I have to use OracleDataSource.
But if I use OracleDataSource, then some fields (e.g. MaxIdle, MAXWait ,maxActive, removeAbandoned, removeAbandonedTimeout, abandonedConnectionTimeout, defaultReadOnly) of BasicDataSource are not supported.

So, How to implement "Fast Connect Failover" (FCF), using spring, in case BasicDataSource is used.

Uses Violation when Importing the same package (same version)

Functionality disappeared without any error message

candy.chiu.ad — Tue, 09 Feb 2010 05:17:45 GMT

I have encountered a problem where one of the functionalities of my application stopped working without generating any error messages.

My application has two basic features: list existing data of and add data to a table in the database via jpa/eclipselink. I was able to deploy the application and the list function worked flawlessly. The add function however didn't work. It didn't generate any error messages neither (based on the dm server log).

I experienced the same problem back in dm server version 1.0. I solved it by adding two bundles to the Import-Bundle section of the MANIFEST file of the jpa project. The reason why I was able to discovered the two missing bundles is because I had a working copy to compare against. This 1.0 fix didn't work in version 2.0.

I have tried fixing my MANIFEST file by copying the content of the greenpages.jpa MANIFEST, generating MANIFEST with bundlor, and importing the entire springframework library. None of them worked.

My question is what's the recommended and reliable way for generating MANIFEST? It is almost impossible to debug when there isn't even an error message.

log4j issue with spring jms, weird output

brianfeng221 — Tue, 09 Feb 2010 04:19:52 GMT

Hi guys:

I use spring jms and log api is log4j.. However, I found it sometimes print out the different thread name from the same code place.

it sometimes use CBBQ100000012Avalon , sometimes use db.dsch_pyrln2prepDistributor and sometimes use Dispatcher-Channel-1.
Also, if it logged by thread db.dsch_pyrln2prepDistributor, the msg will get duplicated. this is really annoying.. I tried to have system.out.println() just below the logger.info, there is no duplicate for system.out.

Really cannot explain :(

@ContextConfiguration does not take a @Configuration class

satishkt — Tue, 09 Feb 2010 04:19:10 GMT

I was hoping that I could pass in a class annotated with @Configuration into @ContextConfiguration and extending Spring's TestNG integration class which would be able to build the context from the beans defined (using @Bean) in the Configuration class.

This would have given me the benefit of loading only the essential bean dependencies that my test bean needed, injecting mocks for the ones that I cant create in a unit test and also not having to create an xml file for individual tests (I guess I would write a seperate @Configuration java file for each test, but I could use the inheritance to easily manage those).

But the @ContextConfiguration provides options only for passing in xml(s) files only. Is there a different way to achieve what I want (I did look thru the API docs but could not find anything that seems to fit my purpose).

thanks

private boolean value should false but always true!!

logixplayer — Tue, 09 Feb 2010 03:31:09 GMT

Hi people,

I have the following controller set up:

Code:

@Controller

@RequestMapping(value={"/person/*","/education/*","/business/*"}, method=RequestMethod.GET)

public class PersonController {

        

        private static final Log log = LogFactory.getLog(PersonController.class);

        private boolean isEdit;

Under this condition, isEdit is set to true:

Code:

                if (user !=null && user.getUserName().equalsIgnoreCase(person)) {

                        isEdit = true;

Now, when isEdit is set to true the first time, on subsequent calls to PersonController, isEdit is always true!!! But this is not a static variable at all. IsEdit is a boolean and should always be set to false when this class is loaded. It seems like the class is loaded only once? Spring singleton or something. Even if that were true, why is a private variable not set to its default value???(of false)

Could it be just my debugger...its been acting strange ever since I started using Tuckey. I was getting LazyLoadingExceptions someitmes while at other times I wasn't....

Please advise.

Spring Batch Admin displays incorrect Dates

afryer — Tue, 09 Feb 2010 02:56:05 GMT

Spring batch admin is currently displaying all dates 10 hours earlier than they actuallly are. My timezone is GMT +10 which would explain why this is happening; Spring Batch Admin is display the times in GMT. How can I stop this from happening? The times in the actual database are displaying correctly when selected.

Which namespace is the http element in?

SimpleWebServiceOutboundGateway for non-spring based ws

jin1212 — Tue, 09 Feb 2010 02:41:06 GMT

This question might be answered already but can I use

Code:


                     request-channel="inputChannel"

                     uri="http://example.org/externalWS"/>

to call out non-spring based WS (external WS)?

The idea that the client is agnostic of available web services. I want to setup a gateway using Spring Integration to receive multiple types of SOAP messages from the client, execute some business logic and route them to the appropriate external WS using SimpleWebServiceOutboundGateway and return them back to the client.

thanks

LazyInitializationException in JPA-based UserDetailsService

andrews — Tue, 09 Feb 2010 01:16:03 GMT

I'm setting up a UserDetailsService that retrieves the user's details via JPA, as recommended by Ben. My service looks like this (where Person and Skill are my own Roo-managed entities):

Code:

public class JpaUserDetailsService implements UserDetailsService {



    @Override

    public UserDetails loadUserByUsername(String username)

        throws UsernameNotFoundException

    {

        Person person = Person.find...; // find the person with this username (via JPA)

        Iterator skills = person.getSkills().iterator(); // !!!

        ...

    }

}

The line marked "!!!" throws this error:

This surprised me, because Roo by default adds the following filter to web.xml:

    org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter







    Spring OpenEntityManagerInViewFilter

    /*

The LazyInitializationException is easily fixed by making my JpaUserDetailsService transactional (e.g. by adding the @Transactional annotation to it), but I'm unclear why that's necessary. Doesn't every thread already have an open Hibernate session (or EntityManager in JPA-speak) thanks to the OEMIV filter?

Best way to reference/locate schemas behind firewall

dc_maf — Tue, 09 Feb 2010 01:02:26 GMT

My web service will live inside a private network with no access to the Internet. What is the best approach in terms of URI schemes to use and locations to put the schemas in order to ensure that neither the client nor server need to access the outside Internet when processing WSDL or request/response messages (preferably without disabling all validation)?

My schema is a single document which only references the XMLSchema namespace, and the WSDL references only those two namespaces and http://schemas.xmlsoap.org/wsdl/.

I'm currently using DefaultWsdl11Definition to generate the WSDL so an approach compatible with that would be preferred but not essential.

The system will have multiple servers, so an http reference to a location on the server won't work.

Does inlining the schema in the WSDL document ensure that parsers will not attempt to locate it using its URI? Can the WSDL schema (and XMLSchema) be inlined similarly within the wsdl:types element? If so, is there any way to get DefaultWsdl11Definition to do so automatically?

Thanks,

Marc

Load properties from DB

tony1234 — Tue, 09 Feb 2010 01:02:23 GMT

Is there support to load properties Resource from the database using PropertyPlaceholderConfigurer?
Or what is the extension point if I need to write my own DatabaseResource and support like

ibatis:my.properties

Generic and Dynamic Classes

Babyangel — Mon, 08 Feb 2010 23:31:20 GMT

Hi,

I'm not sure how best to configure my beans to allow me to dynamically create and manage objects.

The servlet has no idea what class it'll need to create, but once it gets the information (in the form of an xml class) it needs to go about manufacturing the relevant classes.

so imagine i get an xml tag like:

PHP Code:


		
			
<properties>

    <type> Source type>

    <name> Blooper name>

    <delay> 

        <type> Deterministic type>

        <parameters>

           <param>  4 param>

        parameters>

    <delay>

properties>

This would be in the information necessary to instantiate a class:

Source(String name, DistrbutionSample delay)

Where Deterministic is a class that extends distributions sample and param is a value needed to contruct a deterministic class.

I cant hard code the values like:
ApplicationContext context = WebApplicationContextUtils.getWebApplicationContex t(getServletContext());
Source src = (Source) context.getBean("source");

because the servlet doesnt know if it needs to create instance of type SOURCE. There are numerous other classes it may need to instantiate, and the information is being set by the flex layer usnig xml strings.

Any help with this would be much appreciated. Thanks.

detaching object in Hibernate

benhsu_bfly — Mon, 08 Feb 2010 23:25:34 GMT

Hi

I have an POJO I retrieved from the database with Hibernate. I would like to "detach" this object. By this I mean, I do not want any changes made to the object to be reflected in the database until getHibernateTemplate().saveOrUpdate() has been called on it.

Is there a way to do this? I looked in the HibernateTemplate javadoc and didnt see anything

Thank you!
