Quercus, Glassfish v3 & java_bean()
No comments Posted in: Java, JavaEE6, PHPTagged with Java, JavaEE, PHP, Quercus
Current Quercus java_bean() method does not work in Glassfish v3, because Caucho are cooking their own soup with everything new of JavaEE6 (I don’t understand why they need to reinvent all of JavaEE6 like JSF, CDI, etc. for their own app-server… why don’t use something existing and build on top of it? Why don’t push your own projects further, like Quercus, Hessian, Burlap and co.? )
If you, like me, want to use managed beans from inside your php code, and find out, that jndi_lookup and java_bean() do not work (= return null every time), try this little method
function my_java_bean($name)
{
$beanManager = quercus_get_servlet_context()->getAttribute("javax.enterprise.inject.spi.BeanManager");
$beans = $beanManager->getBeans($name);
if($beans == null || )
return null;
$object = $beanManager->getReference($beans[0], $beans[0]->getClass(), $beanManager->createCreationalContext($beans[0]));
return $object;
}

FileUpload with JSF 2 and Servlet 3.0
No comments Posted in: JSF, Java, JavaEE6, Open SourceTagged with Facelets, Java, JavaEE, JSF, JSF2, Servlet 3.0
As I had serious problems with FileUpload and the existing “solutions”, mainly Tomahawk, MyFaces, RichFaces, PrimeFaces, etc. which are all not 100% ready for JSF 2.
I created a taglib based on the code of BalusC.
You can find the Taglib on Github
The source code is based on these two posts:
Simply check out the code with git
git clone http://github.com/domdorn/fileUploadServlet3JSF2.git
then install the taglib with
mvn clean compile install
and import it into your maven project like this
net.balusc
fileUploadServlet3JSF2
1.0-SNAPSHOT
You can then use the taglib in your Facelets files like this:
Upload.xhtml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html

public String submit()

if(file != null)
{
this.filename = file.getName();
}
System.out.println(“processed”);
// do what you want with the file
return “yeah”;
}
public UploadBean() {

Quercus + PostgreSQL + JNDI + PEAR::DB
No comments Posted in: Java, Open Source, PHPTagged with Java, JDBC, JNDI, PEAR, PHP, PostgreSQL, Quercus
If you trying to migrate a legacy PHP application which still uses PEAR::DB to Quercus with PostgreSQL and JDBC-Connection Pools accessible through JNDI, this may come handy for you!
1. Create your Datasource e.g. in Glassfish v3’s admin console… I named mine jdbc/postgresDS
2. copy the file pgsqljndi.php to /usr/share/php/DB/pgsqljndi.php (or wherever you include your PEAR stuff from..)
3. change the database connection creation part of your script to this:
$db = & DB::connect("pgsqljndi://java:comp/env/jdbc/postgresDS");
if(DB::isError($db))
{
// error handling
}
4. remove stuff like this from your scripts
$db->query("SET NAMES 'utf-8'; ");
Your database connection with PEAR::DB, Quercus, PostgreSQL, JDBC + JNDI should work now!
