I'm creating a solver factory based on an XML file using the built in
solverFactory = SolverFactory.createFromXmlResource("solverConfig.xml");
This works fine until compiling into a Quarkus native application, now I get reflection issues from Optaplanner enums:

I can work through these issues by adding #RegisterForReflection on my class calling SolverFactory.createFromXmlResource("solverConfig.xml"), but it feels like these reflection registrations should not have to be a manual step. Currently I'm at #RegisterForReflection(targets = {EnvironmentMode.class, RandomType.class, DomainAccessType.class}), but I'm guessing there will be a lot more enums to add to that list... Should it really be this complex? I'm using the Quarkus Optaplanner dependency
<dependency>
<groupId>org.optaplanner</groupId>
<artifactId>optaplanner-quarkus</artifactId>
</dependency>
By doing it another way, I was able to solve the issue.
In my class that previously called solverFactory = SolverFactory.createFromXmlResource("solverConfig.xml"), I now just inject the factory:
#Inject
SolverFactory<Schedule> solverFactory;
And moved the XML file name to application.properties instead:
quarkus.optaplanner.solver-config-xml=solverConfig.xml

I have a Spring project (not using Spring Boot, if that's relevant) that I'm trying to connect to a local database using the Postgres JDBC driver. (The local database is actually Yugabyte, but that should be fully compatible with the Postgres driver.)
When starting the application, I get this error message:

I can't place this error at all. There is one similar question on Stack Overflow, but there the asker seems to actually know what they're doing and how this is related to spring integration. I, however, am not aware at all that I'm trying to 'reuse' anything. The referenced question also doesn't seem to be related to database configuration.
My setup/configuration is a bit involved, so I'll try to quote the parts that seem relevant.
I have a dao layer project that has the following gradle dependencies (among others):
implementation("org.springframework:spring-context:5.2.2.RELEASE")
implementation("org.springframework:spring-jdbc:5.2.2.RELEASE")
implementation("org.jooq:jooq-kotlin:3.14.11")
runtimeOnly("org.postgresql:postgresql:42.2.19.jre7")
In the same project, I have some configuration (in Kotlin):
#Configuration
open class Config {
#Bean
open fun jdbcTemplate(dataSource: DataSource): JdbcTemplate = JdbcTemplate(dataSource)
#Bean
open fun dslContext(): DSLContext = DefaultDSLContext(SQLDialect.POSTGRES)
#Configuration
#Profile("!unittest")
open inner class NonTestConfig {
#Bean
open fun dataSource(): DataSource {
return DriverManagerDataSource().apply {
// Hardcoded properties to be replaced by values from property file
setDriverClassName("org.postgresql.Driver")
url = "jdbc:postgresql://localhost:5433/demo"
username = "yugabyte"
password = "yugabyte"
}
}
}
}
(Notes: the DSLContext bean is used for JOOQL, included for completeness' sake. The inner class config is there because there is also a separate unit testing config for an embedded database - that one works fine!)
Now, the above project is used in my top-level project that contains the actual application. It's a maven runtime dependency there. I import the config class in this project's XML configuration, using this method:
<context:annotation-config />
<bean class="my.package.Config" />
Then trying to start the application produces the error message.
I figured out what the problem was, but I still don't know how it relates to a <splitter>.
The problem was that the Config class, apart from the database stuff, also included a bean to encrypt data. It turned out that this bean was also defined in another library used by the top-level project. Fixing this duplicate bean problem made the error go away.
I discovered this in a roundabout way: I included the dao project and its configuration in a different top-level project that uses Spring Boot. This led to a clear error message about the encryptor bean having two definitions.
If anyone can explain why the error message is so cryptic in the non-Boot case, that would be a nice complementary answer.
When using ServiceTasks with IntermediateTimerEvents sometimes it did not execute the service task due to exception raised in ACT_RU_JOB table. EXCEPTION_MSG_ column in ACT_RU_JOB table is populated with Unknown property used in expression: #{serviceTask1.execute(execution). value for that particular job.

The exception is totally expected because you don't set the appropriate process variable when starting your process instance. Also Activiti engine is not able to resolve named bean serviceTask1.
From the Activiti 5.22.0 userguide docs (inside the file activiti-5.22.0.zip), more precisely section 8.5.3. Java Service Task you have 4 ways of declaring how to invoke Java logic.
Specifying a class that implements JavaDelegate or ActivityBehavior.
Evaluating an expression that resolves to a delegation object.
Invoking a method expression.
Evaluating a value expression.
In your BPMN process definition file you are invoking service task Java logic with method expression technique. If you want to successfully invoke your method you have to make sure your bean serviceTask1 is a process variable from your execution or a named object in Spring context.
Unfortunately you don't provide necessary information to your BPM engine on where to find your bean with Java logic.
I suggest you the following steps.
Read the technical and userguide documentation (chapter 8.5.3. Java Service Task), from the provided links.
Try to invoke Java logic with the way of specifying a class that implements JavaDelegate or ActivityBehavior. In my humble opinion it is far more easier to get the first touch with Activiti BPM engine.
I'm using springFramework and I try to setBeanDefinitions, the problem is that this methode need a Map beanDefinition as a param... could U tell me plz how I could instantiate this param?
NullPointerException at com.liferay.portal.spring.util.SpringFactoryImpl.setBeanDefinitions(SpringFactoryImpl.java:56)
additional information:
I try to deploy a liferay project without using liferay configuration files (only springFramework libraries), I created my own sessionFactory, my own dataSource ... etc!!
when I run the program, I'm able to create dataBase Schema basing on portlet-hbm.xml information... well now I try to instantiate beans for portal-spring.xml.. (which are xxxxpersistance.java)! those latters told me that they use 'com.liferay.portal.kernel.dao.orm.SessionFactory' as a required type and it can not convert property value of type 'org.hibernate.impl.SessionFactoryImpl'!! so I tried to use the liferay libraries only for those beans and I try to instanciate them manually... but I wasn't able to setBeanDefinitions cause I need a Map beanDefinition as a param... I don't know if there is a way to get them using sessionFactory or not!!
Thanks again
You only mention junit in the tags to your question. I'd recommend to write unit tests without relying on the whole Liferay infrastructure. That will tremendously lower your required setup efforts and simplify your life a lot.
I am trying to access facebook data via spring social facebook integration using the instructions provided at http://spring.io/guides/gs/accessing-facebook.
But currently i am facing 2 type of problem
When i run example as mentioned in tutorial i get following error
No matching bean of type [org.springframework.social.facebook.api.Facebook] found for dependency
When i run this with #Configuration on FacebookConfig class, i get below mentioned error
A ConnectionFactory for provider 'facebook' has already been registered
Is there a workaround to it?
I have kept the war file with source code at https://skydrive.live.com/redir?resid=EA49CD7184E0E40!168&authkey=!AIkoKKx5-Um8AQE
What version are you using?
Try using the version 1.1.0.RELEASE
<dependency>
<groupId>org.springframework.social</groupId>
<artifactId>spring-social-facebook</artifactId>
<version>1.1.0.RELEASE</version>
</dependency>
If it not works, please try post the stacktrace printed.
You need to create a the beans to your class, please post more information like your pom.xml and your spring context configuration.
Ihad the same problem. Spring Social Facebook will automatically add connection factory based on the configuration in application.properties. This auto-configured connection factory is clashing with the one that you're trying to add. Try just to remove your connection factory you add through addConnectionFactories.
Try to use different setting to load your custom connection factory...
E.g. Instead of using OOTB keys use different keys:
#Facebook Social App Details:
# Commented below 2 OOTB Keys & Bingo it worked.
#spring.social.facebook.appId=APP_ID
#spring.social.facebook.appSecret=APP_SECRET
facebook.app.id=APP_ID
facebook.app.secret=APP_SECRET
This will resolve your problem.

This doesn't seem have any impact on any beans in my applicationContext.xml but it's still odd. For me, this looks as if IBM classes are leaking into my application.
How can I fix this? I already set the option "Access to internal server classes" to "Restrict".
It was indeed a class-loading issue, however this cannot be solved by changing class-loader settings.
The problem was that the xml-apis and javax.xml jars were being imported over some maven dependencies.
Since we already set the class loader policies for the application to PARENT_LAST, the javax.xml.transform.TransformerFactory was being loaded from the WebApp-Class loader from our jar files.
However its implementation 'com.ibm.xtq.xslt.jaxp.compiler.TransformerFactoryImpl' was coming from the server class loader, this one was linked to the javax.xml.transform.TransformerFactory provided by the JDK/JRE.
Since the classes were loaded from different sources a ClassCastException was thrown.
Removing all dependencies to xml-apis / xerces / javax.xml jars solved the problem.
Since these APIs are now part of the JDK they no longer need to be imported.
... and if you wonder why I know so much about this issue: I work together with Aaron. ;)
I can't speak for Restrict as I have no personal experience with it,But I think the problem is more to do with IBM Class Loader. The class you are referring to is part of IBM Java implementation of TransformerFactory, I think you can try one of the following to solve this issue on hand
Either change the server class loader policy to PARENT_LAST (This way class loader will find the class from application's local class path, before going to up the chain all the way to java run time)
The other option would be look at the jaxp.properties file, I think it is located in (was_root\java\jre\lib), I only read about this option never actually used it
Why do you say IBM classes are leaking into your application?
The TransformerFactory is asked to create a newInstance. It follows a sequence of steps to determine which TransformerFactory to use. If none of the config is specified, it simply chooses to use the default factory.
Here is the javadoc for TransformerFactory:
http://download.oracle.com/javase/1.5.0/docs/api/javax/xml/transform/TransformerFactory.html#newInstance()
What is the OS ? Is that AIX?
http://www.ibm.com/developerworks/java/jdk/aix/j664/sdkguide.aix64.html
Looking at this doc (link above) for AIX it tells me that this is the default Impl:
javax.xml.transform.TransformerFactory
Selects the XSLT processor. Possible values are:
com.ibm.xtq.xslt.jaxp.compiler.TransformerFactoryImpl
Use the XL TXE-J compiler. This value is the default.
Post back additional information so that we can try and troubleshoot this.
