bug shot -> Error filterStart

I created a SSH(Struts2.1, Spring2.5, Hibernate3.2)  project. It was released on tomcat server of version 5.5. .JDK version is 1.5.

when I start the tomcat server, I got a error followed:

 

org.apache.catalina.core.StandardContext start 

SEVERE: Error filterStart

org.apache.catalina.core.StandardContext start 

SEVERE: Context startup failed due to previous errors 

 

 

I build my project step by step.

1, Add Spring and  Hibernate into the pro.when I run server to test it, everything is ok.

2, Add Struts into the project already containing Spring and Hibernate. When I test it again, the error occur.

 

 

There are two general solutions on internet. One is you missed some jar files such as common-beanutils.jar, common-digester.jar. another is upgrade your jdk from version 5 to 6 or from jre to jdk.

 

 

I followed and done this, but it did not work. The issue is not fixed yet.

 

I create a new project only containing Struts, but it work fine. I think there must be something wrong between spring and struts. It is so strange.

 

I tried again and again. finally I thought about steps I add spring and hibernate to a project only containing struts. It contains two steps followed:

 

1,  add to web.xml
	<filter>
		<filter-name>openSessionInView</filter-name>
		<filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
	</filter>
	<filter-mapping>
		<filter-name>openSessionInView</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
	
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:beans.xml</param-value>
	</context-param>
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

 

2,  add to struts.xml
<constant name="struts.objectFactory" value="sping"/>

  

 

the two steps means add spring and hibernate to the project. when I add this into the two configuration files, "Error filterStart" occured. when I didn't , everything is ok.

 

I devide the two steps. When I did first step, I stoped and run the tomcat to test it. result is totally unbelievable,  it explain that struts, spring and hibernate are all ok in a project.

 

then I focus on the two step, I don't understand why it is wrong to initial struts action object by spring context. At last I found that I missed a letter r in value="sping".  After changing , everything is ok again!  I write this and hope it will be helpfull for you to shot your bug .
