Comments on: Spring JDBC Template – A leaner alternative to fat Hibernate http://www.wetfeetblog.com/spring-jdbc-template-leaner-alternative-fat-hibernate/328 Sun, 22 Jan 2012 04:28:08 +0000 hourly 1 http://wordpress.org/?v=3.3.1 By: Aleksandar http://www.wetfeetblog.com/spring-jdbc-template-leaner-alternative-fat-hibernate/328/comment-page-1#comment-1116 Aleksandar Sat, 12 Nov 2011 13:36:29 +0000 http://www.wetfeetblog.com/?p=328#comment-1116 Very nice :)) When I use json.POJO Mapping . I get this error : http://stackoverflow.com/questions/5161466/how-do-i-use-the-jersey-json-pojo-support , so I commented that part out. It maps all my pojos to json perfectly fine without it. So I don't know why exactly I need it. When I load the beans from applicationContext.xml they usually print out some of the things they do in the tomcat console (like when c3p0 created its connection pool). But this doesn't happen. Hm? And to actually use the beans I also created a common class like that. public class Common { private static ApplicationContext context; public static ApplicationContext getContext() { if (context == null) { context = new FileSystemXmlApplicationContext( "classpath:applicationContext.xml"); return context; } return context; } } which actually seems to create the beans when from the applicationContext when i call it. I would really like even the first call of my webservice to use those already created beans. Am I doing something wrong? :) Thanks a lot for the help! Very nice :) ) When I use json.POJO Mapping .

I used Json pojo marshaling feature. You need to use spring specific jersey servlet ;)
Here is what I have used in the past:

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>

<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<servlet>
<servlet-name>archetype-api</servlet-name>
<servlet-class>com.sun.jersey.spi.spring.container.servlet.SpringServlet</servlet-class>
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>Your.package.name.for.rest.resources</param-value>
</init-param>
<init-param>
<param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
<param-value>true</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>

all spring beans where defined in applicationContext.xml found on the classpath. I used Json pojo marshaling feature.

Answer depends on the implementation you are using. Post your servlet definitions section of the web.xml. Answer depends on the implementation you are using.

Thanks a lot!!! But now all the beans are loaded when a service is called and it can be seen visually that the first call is waaay slower than the next ones. (everything is created at that time) Sorry if the questions are noobish, but i'm kinda new to this. Thanks. It is fine, I got it up and running. Thanks a lot!!!

ApplicationContext context = new ClassPathXmlApplicationContext(new String[] {“applicationContext.xml”, “applicationContext-part2.xml”});

or

ApplicationContext context = new FileSystemXmlApplicationContext(new String[] {“applicationContext.xml”, “applicationContext-part2.xml”});

A great overview! I got to work with c3p0 but so far only setting it up from the java class. I use the Spring JDBC layer but so far couldn't manage to use an XML configuration for Spring. I search over the internet for that, but nobody seems to mention how to setup this. I use spring.framework jars only including them to my classpath so nothing is generated automatically with any applicationContext.xml or anything. Thanks in advance. Hi there. A great overview!
