2013年4月18日部署spring mvc +jbpm4出现的常见错误

1》org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [com.config.spring.application-

context.xml]; nested exception is java.io.FileNotFoundException: class path resource [com.config.spring.application-context.xml] cannot be opened because it

does not exist
原因是：
在web.xml文件中加载spring配置文件时application-context.xml没有找到，当初照着包考
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:/com.config.spring.application-context.xml</param-value>
    </context-param>
     出现的是com.config.spring需要把.换成/就ok了
例如：
    <context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>classpath:/com/config/spring/application-context.xml</param-value>
    </context-param>

2》The matching wildcard is strict, but no declaration can be found for element 'mvc:default-servlet-handler'.
原因是：jar版本和

对不上
3》Factory method [public org.jbpm.api.ProcessEngine org.jbpm.pvm.internal.processengine.SpringHelper.createProcessEngine()] threw exception; nested

exception is org.jbpm.api.JbpmException: no jBPM DB schema: no JBPM4_EXECUTION table.   Run the create.jbpm.schema target first in the install tool.

原因：是因为jbpm4 表没有找到table(JBPM4_EXECUTION )
