Thank you for atention.



This is my PHP code. 

OBJ is a instance of java class called "Contato" (Contact)

grava() is a GenericDAO's method that insert record in DB.

Jar's needed by hibernate and mysql are already included into Contato.jar

I did many tests in java enviorment, and "grava()" works fine.

// =========================

require_once("../WEB-INF/java/Java.inc");


java_require("../WEB-INF/lib/Contato.jar");


$obj = new Java("br.edu.utfpr.beans.Contato","name","phone","mobile");


$dao = new Java("br.edu.utfpr.dao.GenericDAO");


//echo $obj->getNome();


$dao->grava($obj);



// ============================

public void grava(Object obj)

{

Session session = HibernateUtil.openSession();

Transaction tx = session.beginTransaction(); 

session.saveOrUpdate(obj);

tx.commit();

session.close(); 

}

// ===========================

Problem solved. I uninstalled jdk and tomcat and instaled jre1.5.0_16 and tomcat_5.5.27.

We can't really help you with application-level problems; grava() has received a valid object, everything below this level is outside of the scope of the PHP/Java Bridge.

However, please include the stack trace, and some code which shows what you're trying to do.

Hello

i'd started to use PHP / Java Bridge some days ago, and im finding a lot of dificulties to use hibernate or even simple JDBC.

After add all jars needed and created new Java("GenericDAO"),  i tried to call save method, but something wrong happens.

PHP Fatal error:  Uncaught [[o:Exception]:"java.lang.Exception: Invoke failed: [[o:GenericDAO]]->grava((o:Object)[o:Contato]). Cause: java.lang.NullPointerException VM: 1.6.0_03@http://java.sun.com/" at:


Maybe someone got an exemple to help me, please.


My monograph of the university is about PHP JAVA BRIDGE, and i have just a few days do finish. Please, help me.
