I have an application in which the interface is based on Spring Roo 1.1.2 jspx files.
Everyone thinks it works well in Tomcat 6, but if I deploy the same application in Websphere 7 (class loader: parent last), I get an exception:
java.lang.ClassCastException: java.lang.NullPointerException is incompatible with javax.el.ELException

The app has a Flex / BlazeDS part that works great. But there is this part of JSP (x). Spring controllers work, but something is wrong with JSPX, and I don’t know where to start when I understand the specification right, than WAS7 provides JSP 2.1, this is exactly what I need.
The corresponding POM part for WAR:
<dependency> <groupId>javax.servlet</groupId> <artifactId>com.springsource.javax.servlet.jsp.jstl</artifactId> <version>1.2.0</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.5</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>jsp-api</artifactId> <version>2.1</version> <scope>provided</scope> </dependency>
Can someone give me a hint?
