Hi there.
I'm using this environment:
- Eclipse Indigo
- Maven 3.0.4
- GWT 2.4.0
- GWT-dispatch 1.2.0
- Spring 3.1.1
- JVM 1.6
Here there is my web.xml file:
Code:
<?xml version="1.0" encoding="UTF-8"?>
<web-app..>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:spring-gwtDispatch-context.xml,
classpath:spring-application-context.xml
</param-value>
</context-param>
<context-param>
<param-name>log4jConfigLocation</param-name>
<param-value>/WEB-INF/classes/log4j.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>dispatch</servlet-name>
<servlet-class>x.y.server.gwt.dispatch.spring.SpringStandardDispatchServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatch</servlet-name>
<url-pattern>/test/dispatch</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>Test.html</welcome-file>
</welcome-file-list>
</web-app>
The first issue I have is that when I write the xml files one by one spring container is able in reading them. But previously (in application without using GWT) in the web.xml I could write also:
Code:
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:spring-*-context.xml
</param-value>
</context-param>
In this case the spring container was able in reading all xml files whose names started with spring and finished with context. Now if i write as I showed the ContextListener seems to search for the only one file the one called "spring-*-context.xml"
Content of spring-gwtDispatch-context.xml
Code:
<?xml version="1.0" encoding="UTF-8"?>
<beans ... >
<context:annotation-config />
<context:component-scan base-package="x.y.commoncore.al.server" />
</beans>
Content of spring-application-context.xml
Code:
<?xml version="1.0" encoding="UTF-8"?>
<beans....>
<context:annotation-config />
<context:component-scan base-package="x.y.server" />
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" >
<property name="locations" value="classpath:configuration.properties" />
</bean>
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" depends-on="org.h2.tools.Server" destroy-method="close" >
<property name="driverClassName" value="${DB_DRIVER_CLASS_NAME}" />
<property name="url" value="${DB_URL}" />
<property name="username" value="${DB_USERNAME}" />
<property name="password" value="${DB_PASSWORD}" />
<property name="initialSize" value="${DB_POOL_INITIAL_SIZE}" />
<property name="maxActive" value="${DB_POOL_MAX_ACTIVE_CONNECTIONS}" />
<property name="minIdle" value="${DB_POOL_MIN_IDLE}" />
<property name="timeBetweenEvictionRunsMillis" value="${DB_POOL_TIME_BETWEEN_EVITIONS}" />
<property name="validationQuery" value="${DB_POOL_VALIDATION_QUERY}" />
</bean>
<bean id="org.h2.tools.Server" class="org.h2.tools.Server" depends-on="org.h2.tools.Server-WebServer" destroy-method="stop" factory-method="createTcpServer" init-method="start" scope="singleton" >
<constructor-arg value="${DB_H2_TOOLS_SERVER_CONSTRUCTOR_STRING}" />
</bean>
<bean id="org.h2.tools.Server-WebServer" class="org.h2.tools.Server" destroy-method="stop" factory-method="createWebServer" init-method="start" scope="singleton" >
<constructor-arg value="${DB_H2_TOOLS_SERVER_WEB_SERVER_CONSTRUCTOR_STRING}" />
</bean>
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean" >
<property name="dataSource" ref="dataSource" />
</bean>
<bean id="productDao" class="org.mybatis.spring.mapper.MapperFactoryBean">
<property name="mapperInterface" value="it.poste.crs.invimall.server.mapper.InViMallSampleProductDao" />
<property name="sqlSessionFactory" ref="sqlSessionFactory" />
</bean>
</beans>
Note that both spring-application-context.xml and spring-gwtDispatch-context.xml are inside in two different eclipse maven project (at the end 2 different jars)
When I launch the GWT project by using the GWT Eclipse plugin it seems to me that the container is not able in scanning the beans listed in file "spring-gwtDispatch-context.xml" while it's able in scanning beans listed in the other file.
On other side I built a simple unit test. This is its code:
Code:
public class BeanScanTest {
@Test
public void springBeanScannTest(){
try {
String[] ctxNames = {"spring-gwtDispatch-context.xml","spring-application-context.xml"};
ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext(ctxNames);
} catch (Exception e) {
e.printStackTrace();
}
}
}
In this case the bean scan is OK. In fact I can read the following in the log file:
Code:

When I launch the web application I see:
Code:

10:42:44,546 DEBUG [PathMatchingResourcePatternResolver] Resolved location pattern [classpath*:x/y/commoncore/al/server/**/*.class] to resources []
10:42:44,546 DEBUG [XmlBeanDefinitionReader] Loaded 4 bean definitions from location pattern [classpath:spring-gwtDispatch-context.xml]
As you can see the loaded bean number is different. Can anybody suggest to me why this is happening? I'm fighting with this issue from 3 days
I'm not able in understanding if it's a spring container issue, GWT issue (note that GWT plugin starts by using jetty servlet container) or, more probably, a my issue.
Thank you
Angelo
