java.lang.NoSuchMethodError

[garcima]

Hello everyone:

I was trying to set up the Spring framework to use the JDBC Dao support in a web application. I did the following:

a) Added a <context-param> element to web.xml in my webapp with name "contextConfigLocation" and value "/WEB-INF/AcronetApplicationContext.xml". I put the application context file (obviously) under the "WEB-INF" folder of the web application.

b) Added the following element (after the <listener> elements)

<servlet>
<servlet-name>context</servlet-name>
<servlet-class>org.springframework.web.context.ContextLoade rServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>

c) I deployed the web application to the WebLogic Server 6.1. When deployment finishes it throws the following exception:

What could be happening?

Thanks in advance,

Carlos,

There is a small bug in Spring 1.1.2 that requires JDK 1.4 for some core features. These will be fixed in 1.1.3 which will be released any day now.
