Want to hire an Apache developer?
The Apache Software Foundation, the most respected organization in the open source world, has opened a mailing list to allow posting job offers to the members of the community. Offers can be sent the to jobs (at) apache (dot) org.
Struts Or JSF? Struts And JSF?
Craig McClanahan, the original creator of the Struts Framework and the co-specification lead for JavaServer Faces 1.0 (JSF) has wrotten a very interesting entry in his weblog about Struts and JSF integration, with some comments about Spring and JSF.
Definitively JSF is on the top of my list of TODO tasks.
Avoid duplicated info in the Spring application context
Some configuration is shared across many projects and duplication must be avoided, e.g. for hibernate configuration this can be achieved using ArrayList for properties of type List and a custom class HibernateProperties for properties of type Properties.
${hibernate.dialect} ${hibernate.show_sql} ${hibernate.hbm2ddl.auto} net/sf/oness/party/model/party/bo/Party.hbm.xml
This way mappingResources can be overriden in each project for their set of classes and hibernateProperties can also be overriden to get values from JNDI as I do in the ONess project.
New ONess module order to invoice
The module order which models the process order to delivery docket to invoice has been added to ONess.
Avoiding OutOfMemory errors in Maven (part 2)
As Rick Hightower stated in a previous comment, another way to avoid running out of memory is forking the virtual machine. When doing so the MAVEN_OPTS doesn’t affect the new vm, you have to use the maven.junit.jvmargs
property.
maven.junit.fork=true maven.junit.jvmargs=-Xmx256m
Avoiding OutOfMemory errors in Maven
If you are getting out of memory errors when running Maven you can increase the amount of memory used.
You only need to set the environment variable MAVEN_OPTS, e.g. MAVEN_OPTS=-Xmx512m if you want to use 512 MB of memory.
JDO and EJB join forces
Dion wrote an interesting entry about the joining of JDO and EJB. A new spec is being created to provide an unified persistence API for both standard and enterprise java editions using POJOs.
Released Acegi Security System for Spring 0.6.1
Ben Alex has released the 0.6.1 version of the Acegi Security System for Spring.
For those who don’t know the project provides comprehensive security services for The Spring Framework. I think it’s a must if you need security in your applications (who doesn’t need?). It’s easy and powerful.
FEATURES:
* It is ready NOW
* Easy to use and deploy (eg see samples/quick-start directory)
* Enterprise-wide single sign on (via Yale Uni’s CAS project)
* Reuses your Spring expertise
* Domain object instance security
* Non-intrusive setup
* Full (but optional) container integration
* Keeps your objects free of security code
* Secures your HTTP requests (regular expressions, Ant Paths etc)
* Channel security (HTTPS/HTTP auto redirection etc)
* Supports HTTP BASIC authentication (RFC 1945)
* Convenient security taglib
* Application context or attribute-based configuration
* Various authentication backends (including JDBC)
* Event support
* Easy integration with existing databases (no schema changes)
* Caching (now pluggable, with an EHCACHE implementation)
* Pluggable architecture
* Startup-time validation
* Remoting support (demonstrated in sample application)
* Advanced password encoding (SHA, MD5, salts etc)
* Run-as replacement
* Unit tests (Clover coverage is currently 98%)
* Container integration tests
* Supports your own unit tests
* Peer reviewed
* Thorough documentation
* Apache license
CHANGES IN 0.6.1:
* Resolved to use http://apr.apache.org/versioning.html for versioning
* Added additional DaoAuthenticationProvider event when user not found
* Added Authentication.getDetails() to DaoAuthenticationProvider resp
* Added DaoAuthenticationProvider.hideUserNotFoundExceptions
* Added PasswordAuthenticationProvider for password-validating DAOs
* Added FilterToBeanProxy compatibility with ContextLoaderServlet
* Added convenience methods to ConfigAttributeDefinition
* Improved sample applications’ bean reference notation
* Clarified contract for ObjectDefinitionSource.getAttributes(Object)
* Extracted removeUserFromCache(String) to UserCache interface
* Improved ConfigAttributeEditor so it trims spaces
* Refactored UsernamePasswordAuthenticationToken.getDetails() to Object
* Fixed MethodDefinitionAttributes to implement ObjectDefinitionSource
* Fixed EH-CACHE-based caching implementation behaviour if cache exists
* Fixed Ant “release” target not including project.properties
* Fixed GrantedAuthorityEffectiveAclsResolver if null ACLs provided
* Documentation improvements
As per the Apache APR project versioning guidelines (URL above), this is
a patch release. Existing users of release 0.6 should be able to upgrade
by simply replacing the JAR(s) and testing.
