OVal - object validation framework / News: Recent posts

OVal is a pragmatic, easy to use and extensible object validation framework for Java 5 or later. Constraints can be declared via annotations (@NotNull), POJOs or using XML configuration files. Custom constraints can be expressed in pure Java or by using scripting languages such as JavaScript, Groovy, BeanShell, OGNL, MVEL or Ruby. OVal can optionally use AspectJ to enforce automatic validation (programming by contract aka Design by Contract).... read more

OVal is a pragmatic and extensible validation framework for any kind of Java
objects (not only JavaBeans). Constraints can be configured with annotations,
POJOs or XML. Custom constraints can be expressed in pure Java or by using
scripting languages such as JavaScript, Groovy, BeanShell, OGNL or MVEL.
Besides simple object validation OVal implements Programming by Contract
features by utilizing AspectJ based aspects.... read more

OVal is a generic Java 5 based object validation framework for any kind of Java objects (not only JavaBeans). Constraints can be expressed with
annotations or in XML. OVal supports validation of class fields, method return values, as well as constructor/method parameters. Automatic
validation (programming by contract) can be achieved by using pre-built AspectJ aspects.

Major changes in this release:
* NEW: added support for interpreting EJB3 JPA annotations
* NEW: all configuration classes are now serializable
* NEW: added support for ParaNamer http://paranamer.codehaus.org/ for method parameter name resolving
* various minor fixes... read more

OVal is a generic Java 5 based object validation framework that uses annotations or XML to express constraints and optionally AspectJ to handle automatic validation (programming by contract). It supports validation of class fields as well as constructor and method parameteters.

Major changes in this release:
* NEW: XML based configuration (utilizing XStream)
* NEW: support for alternative Java Collection implementations (e.g. Javolution)
* NEW: constraint sets
* NEW: customizable error message resolver
* FIX: NPE in InstanceOfCheck
* FIX: several serialization issues... read more

OVal is a generic Java 5 based object validation framework that uses annotations to express constraints and AspectJ to handle automatic validation (programming by contract). It supports validation of class fields as well as constructor and method parameteters.

Major changes in this release:
* NEW: added french translation for the violation messages of the built-in constraints (provided by mimil)
* NEW: added @InstanceOf constraint
* NEW: added @AssertValid constraint
* NEW: introduced an ignoreIfNull parameter for the @ValidateWithMethod annotation
* NEW: support for multiple Validator instances
* CHANGE: annotation @PreValidateObject renamed to @PreValidateThis
* CHANGE: annotation @PostValidateObject renamed to @PostValidateThis ... read more

Major changes in this release:
* FIX: net.sf.oval.Validator: Validation of inherited classes throws NullPointerException [ Bug 1461805 ]
* NEW: added support for localizable error messages
* NEW: added support for parameters in constraint violation messages
* NEW: new constraints can now be specified during runtime
* NEW: ApiUsageAuditor aspect that reports warnings about unsupported usage of annotations in Eclipse IDE
* NEW: the instantiation of checks for constraint annotations is now customizable via net.sf.oval.AnnotationCheckLoader... read more
