Suppose that I have an email field annotated with: @NotEmpty(message="Please enter email address") ...

This is how to display the first error only: <spring:bind path="emailAddress"> <c:if test="$...

Mapping Java objects to Jackson JSON is pretty simple. But if you name a JSON field wrong, you'll get the "Unrecognized field ... (Class ...), not marked as ignorable" error. The rule for mapping a Java bean attribute name to a JSON field name is: lower all leading capital letters until the first lower case letter . For example, this Java class: package com.example; public class Person { ... maps to this JSON string: { "firstName": "Jane", "lastName": "... Test code: package com.example; import java.net.URL; ...

Because List<String> is not a reifiable type, the Java Runtime does not have enough information to verify the type or do the type casting.

When you create a new key with Java keytool , it wraps the public key in a self signed certificate. You can generate a certificate signing request with the keytool -certreq command. After a certificate authority (CA) signs the certificate request, you can import the certificate received (a .crt file) back into the key store. Instead of using a CA, you can sign the certificate request with another key (with openssl, for example). If the certificate is not signed by a CA, you'll receive an error: $ keytool -import -alias android-root -file androi... To fix the problem, import the certificate of the signer: $ keytool -import -trustcacerts -file openssl.crt ... Import the certificate again (alias is the alias of the private key whose certificate was...

I tried to convert a private key from PEM to PKCS12 with OpenSSL and got this error: C:\myworks>openssl pkcs12 -export -in openssl_ca3.... The problem was that the -in parameter expects both private key and certificate in the same input file, i.e., openssl_ca3.pem in the above example. Appending the certificate file to the key fixed the problem: C:\myworks>cat openssl_ca3.crt >>openssl_ca3.pem ...
