Anyone who had troubled with this error?
Cannot create PoolableConnectionFactory (unknown system variable 'language')
Programming with java, mysql, ibatis. Added some codes and existing codes make this error as well.
Below are the error messages.

The problem was firewall. The firewall had blocked java to access to database on other computer. When permitted the access, my program started working.

I change my java connector library to mysql-connector-java-5.1.23-bin.jar and it works good.
This problem was in mysql-connector-java-5.1.36.jar

Are you maybe using the buggy MySQL Connector/J? See:
https://confluence.atlassian.com/jirakb/unknown-system-variable-language-on-database-setup-page-when-using-mysql-765400069.html

hibernate exception during commit

We are using Spring 2.5.6 and the Hibernate that comes with it.
As part of our architecture, we have a service and a manager. The service calls the manager to provide a unit of work. We place an AOP interceptor around the manager to manage the transaction.
In our case, the manager is creating an image and a note that links that image to a person, then returning back to the service. These are brand new functions.
When I run this I get the following stack trace:

When I searched on the error, I found a lot entries about queries with null values. The thing is that I've already done the inserts and that worked fine. It's throwing this exception during the commit.
Both image and note are existing fields that I've used in the past. I have recently put a link on note to image so that a note may reference an image.
Just because of the error message, I'm suspicious of the image. Here is the definition of the image data field on the image:
#Column( name = "IMAGE_DATA" )
#Lob()
private byte[ ] imageData;
I'd appreciate any advice as to how to proceed.

The key to the answer is in the lower part of the stacktrace:
ORA-00932: inconsistent datatypes: expected NUMBER got BINARY
Hard to say which field this is about, but since you're working with images there may be something wrong in how you configured persistence for that class / field.
Maybe you should hint Hibernate how to store the field by annotating it with
#Lob(type = LobType.BLOB)

The problem ended up involving a missing annotation.
I had just added an image to note entry and set it up to point to the UUID of the image, but left off #OneToOne. As such, it appeared to be trying to store the image data in a field for UUID.
I Added the #OneToOne and the problem went away. Nathan was also correct in saying that it wasn't actually getting inserted until the commit. To find the issue, I moved these inserts outside of the transaction so that they got inserted immediately. This helped me track down the issue.

Custom cursor behavior

I'm trying to add some custom cursors on my app but every time I receive this error:

And the cursor path is valid, the cursor is visible on app but in log I always find this error. Other problem is that on IE8 the performance is highly impacted only for two custom added cursors. I'm wondering if I must add .cur extension on mime types?
If anyone have e suggestion please let me know, thank you.

So my question would be why are you using java for this you can easily modify your cursor with css, which would be the easiest and best practice as a user can easily disable it if they want.

javax.faces.application.ViewExpiredException: View could not be restored

i've created this webpage using jsf,prettyfaces and hibernate
i looked around and most people says that this error is because of cache
most of them found this error after login,logout and try to login back
but i found this error when i log in,and when i try to navigate to any other page,any link that i clicked will produce this error
what makes it harder is that this error doesnt occur everytime
sometimes when i try restart the server,login back,everythin work just fine
but sometimes when this error occur again, i tried restart the server and try login back.the same error still occur

JSF keeps a (configurable) number of views in the session. You will get this ViewExpiredException if you do a post to a view that cannot be restored anymore, ie. not present anymore in the list of views for that session.
There can be multiple reasons for this. Two possible scenario's I can think of right now are:
Session invalidated/expired
Multiple (> configured number of sessions in view) views being created after the one that should be restored

To my understanding this is caused by the combination of several things:
A JSF-form containing an internal id for a field has been generated.
The JSF-page has been changed, or the whole application redeployed, causing the internal ids to change.
The JSF-form with the old internal id is submitted (a login page?) and the old internal id cannot be found in the new ids for the JSF-page.
You must have the page refreshed in the browser (getting the new id's) before attempting to submit again.

Please provide me Easy solution for the same
Hope for the best co-operation from your side
Thanks in advance !!!

Yes, your authentication is not working because Twitter made some recent changes
regarding how it lets 3rd party code authenticate.
http://news.techworld.com/security/3237604/twitter-turns-on-oauth-api-authentication/
http://www.networkworld.com/news/2010/083110-twitter-api-has-new-third.html?hpg1=bn
http://www.wired.com/epicenter/2010/08/twitter-login-errors/
http://groups.google.com/group/twitter-api-announce/browse_thread/thread/f71eb68600996af8
In other words, Basic authentication has been turned off for the API.
https://apiwiki.twitter.com/Authentication
As Allain mentions, oAuth is the way to go.

The code you posted is different than what I've seen in the past for connecting. I think (though I'm not sure) that oAuth is the preferred way of authenticating now.
Here's a blog that details using oAuth to connect.

I was having that trouble, finally the solution was to put a valid Callback url in my twitter API at (https://dev.twitter.com/‎), I used google+ url, saved changes (it could take a minutes before the changes are made, refresh the page to be sure) and it worked.
