Hi,
I am new to vaadin. We have a legacy application with spring and we want to improve its UI, we are using Vaadin 7 for that. We want both vaadin as well as existing jsp screens to work simultaneously. I have include all the vaadin jars required for the project. The problem I am facing is if I try to open a jsp file I get following error.
javax.servlet.ServletException: java.lang.NoClassDefFoundError: org/apache/tools/ant/BuildException
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:244)
javax.servlet.http.HttpServlet.service(HttpServlet.java:717)

All vaadin screens are working fine. If I remove vaadin jars my jsps also work.
I am using following jars and all are required.
vaadin-client-compiled-7.0.2.jar
vaadin-client-compiler-7.0.2.jar
vaadin-server-7.0.2.jar
vaadin-shared-7.0.2.jar
vaadin-themes-7.0.2.jar
Please provide a solution or let me know in case I am doing something wrong.
Thanks
