问题 I want to build a JEE plugin based architecture. The main idea is do something similar to what eclipse is, but in the context of JEE. My goal is to have a minimum of modules as the core, and allow others modules extend its functionality. To this, I have implemented a test using 4 modules: gauges: Defines and implements a gaugesregistry service, also defines a gauge POJO. cashgauges: implements a gauge producer using CDI. this is a plugin mock. othergauges: implements a gauge producer using

问题 I'm building a simple app and now i'm facing the "logging nightmare" on javaee application. I've done days of searches, hundreds of change/test but there's no way to make it run. My app is made of a simple EAR +-- /lib | +-- slf4j-api-1.7.25.jar | +-- logback-classic-1.2.3.jar | +-- logback-core-1.2.3.jar | +-- JAR (JPA/EJB/Producers/Interceptors) | +--src/main/resources | +-- logback.xml | +-- logback-test.xml | +-- WAR The libs are so loaded in the lib directory of the EAR file. my pom.xml

问题 According to the Java EE 6 Tutorial: The EJB container is responsible for determining when to initialize a singleton session bean instance unless the singleton session bean implementation class is annotated with the javax.ejb.Startup annotation. In this case, sometimes called eager initialization, the EJB container must initialize the singleton session bean upon application startup. The singleton session bean is initialized before the EJB container delivers client requests to any enterprise

问题 I would like to use mybatis with container-managed transaction in my aplication. I use mybatis 3.4.2 and mybatis-cdi 1.0.0. My code works but at the moment I open and close sessions manually and I do not know how to inject either SqlSession or Mapper to my EJB. It seems that mybatis-cdi does not do its job properly in my case. That is my deployment structure: EAR +--- commons.jar (interfaces, POJOs) +--- ejb.jar (stateless EJBs + MyBatis mapper + session factory) +--- web.war (demo servlet

问题 This is a snippet my spring servlet. My pom file has the jackson dependencies added as well but I just can't figure out why I'm getting this 406. ... <mvc:annotation-driven/> <context:component-scan base-package="com.ourcalendar.*"/> <!-- Add JPA support --> <bean id="emf" class= "org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="loadTimeWeaver"> <bean class= "org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver"/> </property> </bean> <!

问题 I have two different domain & sub domain. For example :- Domain 1 :- example1.com IP :- XXX.XX.XX.201 Domain 2 :- example2.com IP :- XXX.XX.XX.202 (This is a virtual hosting on above IP addr XXX.XX.XX.201) I am also using sub-domains for the same like, Domain 1 :- test.example1.com IP :- XXX.XX.XX.201 Domain 2 :- test.example2.com IP :- XXX.XX.XX.202 (This is a virtual hosting on above IP addr XXX.XX.XX.201) I have to access the application in such way that if i access example.com it will

问题 I've abandoned GlassFish 4-point-anything in favor of Payara41. Amazingly GF has unresolved JDBC and JMS Resources configuration bugs. See: Glassfish Admin Console throws java.lang.IllegalStateException when creating JDBC Pool Payara perfectly fixed the JMS configuration issues. So all I need are the environment properties my standalone Java Client needs to get an InitialContext(env) to lookup() those Resources. Note: InitalContext() doesn't work in a standalone. Only in an EJB Container that

问题 This my entity @Entity public class Order { ... @OneToMany (fetch = FetchType.LAZY) @JoinColumn(name="order_uuid", insertable = false, updatable = false) private List<Item> items; } When I create new Oder and save it in DB I get: Caused by: java.lang.IllegalStateException: During synchronization a new object was found through a relationship that was not marked cascade PERSIST: com.temp.Item@3cd8c5f.

问题 We have have a J2EE Struts 2 application. Recently we saw some intrusions are coming to our application which runs on port 80.

问题 I have a J2EE web application that instantiates an Apache Axis SOAP client proxy as a Spring bean. When I deploy the application into a Glassfish 3 server for the first time, it succeeds. However, if I undeploy and redeploy the application, I get the following error (at the bottom of the Spring stacktrace): Instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Factory method [com.foo.bar.FooServicePortType com.foo.bar.config
