I am looking to set-up validation, but I am getting errors. I added the
following to my struts.xml:
<package name="conap" extends="struts-default">
<interceptors>
<interceptor name="cookie"
class="org.apache.struts2.interceptor.CookieInterceptor"/>
<interceptor-stack name="validationStack">
<interceptor-ref name="defaultStack"/>
<interceptor-ref name="validation"/>
</interceptor-stack>
</interceptors>
<default-interceptor-ref name="defaultStack"/>
</package>
The class that I want to validate is defined as follows:
@ParentPackage("conap")
public class SubmitAction extends ActionSupport implements
ModelDriven<Application> {
...
@VisitorFieldValidator
public Application getModel() {
return application;
}
...
@Action(
results = {
@Result(name = "success", location =
"/WEB-INF/content/soldier/login-success.jsp"),
@Result(name = "error", location =
"/WEB-INF/content/soldier/login-error.jsp")},
interceptorRefs = {...@interceptorref("validationStack")}
)
public String execute() throws Exception {
...
}
}
The class that I want to validate is defined as follows:
public class Application {
...
@RequiredFieldValidator(type = ValidatorType.FIELD, message = "Major is
required")
public void setMajorCd(String majorCd) {
this.majorCd = majorCd;
}
...
@RequiredFieldValidator(type = ValidatorType.FIELD, message = "Expected
Entry Date is required")
public void setExpectedEntryDate(String expectedEntryDate) {
this.expectedEntryDate = expectedEntryDate;
}
}
When I submit to the action, I get an exception:
Struts Problem Report
Struts Problem Report
Struts has detected an unhandled exception:
