and it has worked fine for me previously .
I would carry out some checks on the struts action to verify the size of the data.
Sure that stuff works.. Its when i attempt to save the object that has a property or type byte[] (class cast exception) and a trusty old NPE when i use my own custom type. Its really annoying, given that it works with 2.0.. Perhaps those crazy hibernate kids thought it was too easy.
Also check for the following <form enctype="multipart/form-data"

Just downloaded the latest, but the action just prints a test message..
System.out.println("at least i managed to get called");
The problem isn't with form file, thats fine.. Its when I try and save to the db
//hibernate stuff
/** * @hibernate.property column="image" type="blob" */ public byte[] getImage() { return image; }
public void setImage(byte[] image) { this.image = image; }
Now i created a custom user type like were required with older versions
of hibernate..
/** * @hibernate.property column="image" type="com.sparrow.hibernate.type.Image" */
http://www.hibernate.org/73.html
but when i try and save now i get a null pointer exception with not
much else to go on (before it was a class cast exception). I'd have
thought that creating a custom user type was a bit old hat as 2.0 loved
it..
The only other thing i can think its down to is the jdbc driver.. Which
i'm investigating now.

My app is able to do it no problem, back and forth.
You can get the source code from http://jestate.revoltingdigits.com/
ie.jestate.struts.action.ImageUploadAction
My code is a mess at the moment but that code is working.

I've had the same thing happen using DBCP and C3PO, I believe its the
driver rather than the pooling. As I said we've a app thats live, and
i haven't touched it in months using DBCP.
[OT] subject change.. Have you had any joy with byte[] to blob mapping for file uploads with hibernate 2.1.4? I created a custom usertype, but i get a npe. 2.0 delbt with life, but things appear to have taken a step backwards. (please dont make me go the the scary hibernate forum :) )

I noticed this behavior with 3.0.14.
This _really_ sounds like this entry in the Hibernate FAQ to me:
http://www.hibernate.org/117.html#A13
I wouldn't use DBCP though as Gavin King is apparently fed up with it, and built-in support for it is being yanked in the next major version of Hibernate.

Marco
What jdbc driver are you using?
They was a shady version 3 behaving like this.

Hibernate's internal connection pooling isn't meant for production
because it does things just like that.
Suggest you use c3p0 for the pooling.
From my hibernate.cfg.xml, I only had to add this:
<property name="c3p0.minPoolSize">5</property> <property name="c3p0.maxPoolSize">20</property> <property name="c3p0.timeout">1800</property> <property name="c3p0.max_statement">50</property>

Hello,
First of all, I apologize for the off topic issue.. I know this is not the list, but I tried hibernate forums, and Searched the web with no solution.. hopefully some of u
had the Same
problem and solved it..
I m experiencing problems with Hibernate in tomcat,
talking to mysql.
My situation is that I didn't define any connection pools
in tomcat,
but left it to Hibernate to handle that...
After leaving the application running for 11 hours, I got
following
exception
hi all, i have a webapp taht uses Hibernate and MYSQL, running on top of tomcat.
i am letting Hibernate handle the connections to mysql db, since i
have no connection pools defined in tomcat. after running the
application for nearly 9 hours, when i tried to use my app
to connect
to the database i got following exception:
Caused by: net.sf.hibernate.JDBCException: Could not
execute query at
net.sf.hibernate.impl.SessionImpl.find(SessionImpl.java:1476)
at net.sf.hibernate.impl.QueryImpl.list(QueryImpl.java:45)
at com.myapp.hibernate.HibernatePersistenceManager.query(Hibernat
ePersisten
ceManager.java:205)
... 31 more
Caused by: java.sql.SQLException: Communication link failure:
java.net.SocketException, underlying cause: Software caused
connection
abort: recv failed
** BEGIN NESTED EXCEPTION **
java.net.SocketException MESSAGE: Software caused connection abort: recv failed
STACKTRACE:
java.net.SocketException: Software caused connection abort: recv failed
now i have searched the web and found two possible
alternatives.. one
was to add following problems to hibernate config file.. <property
name="connection.autoReconnect">true</property>
<property name="connection.autoReconnectForPools">true</property>
<property
name="connection.is-connection-validation-required">true</
property>
but this does not work, as ihave added thos eproperties to
hibernate
properties file and i am still getting same exception
then I tried to add ?autoReconnect=true to JBDC URL, but
that didn't
------------------------------------------------------------------ --work either coz I left application running for 11 hours and after
that I got same exception...
can anyone help me out?
THANX in advance and regards marco
