I like to know how to configure my spring mvc configuration xml file to get connected to openshift postgresql 9.2 database. I
Check your JSP file for missing or wrong attributes values inside the html tags.
Spring MVC checks for well-formed html tags. If you missed fill any attributes or those attributes have wrong values, it won't run and will give you an error message related to JasperException.
I recommend using the spring tag namespace when using forms:
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<form:input type="text" class="form-control" placeholder="Login" maxlength="10" size="10" path="" name="login"/>
Eclipse in this case is very helpful because if something is wrong it will tell you.
