I am working on project that must need to protect data (revealing code is not main problem) files. We are using Java + Netbeans. Is there any facility that will create jar in encrypted format? We are also using sqlite for database - so putting text file in encrypted format is not proper option for us too.

I'm struggling to get my head round how the HiLo generator works in NHibernate. I've read the explanation here which made things a little clearer.
My understanding is that each SessionFactory retrieves the high value from the database. This improves performance because we have access to IDs without hitting the database.
The explanation from the above link also states:
For instance, supposing you have a "high" sequence with a current value of 35, and the "low" number is in the range 0-1023. Then the client can increment the sequence to 36 (for other clients to be able to generate keys while it's using 35) and know that keys 35/0, 35/1, 35/2, 35/3... 35/1023 are all available.
How does this work in a web application as don't I only have one SessionFactory and therefore one hi value. Does this mean that in a disconnected application you can end up with duplicate (low) ids in your entity table?
In my tests I used these settings:
<id name="Id" unsaved-value="0">
<generator class="hilo"/>
</id>
I ran a test to save 100 objects. The IDs in my table went from 32768 - 32868. The next hi value was incremented to 2. Then I ran my test again and the Ids were in the range 65536 - 65636.
First off, why start at 32768 and not 1, and secondly why the jump from 32868 to 65536?
Now I know that my surrogate keys shouldn't have any meaning but we do use them in our application. Why can't I just have them increment nicely like a SQL Server identity field would.
Finally can someone give me an explanation of how the max_lo parameter works? Is this the maximum number of low values (entity ids in my head) that can be created against the high value?
This is one topic in NHibernate that I have struggled to find documentation for. I read the entire NHibernate in action book and it still doesn't go into how this works in any detail.
Thanks

I have an xml document that was serialized into a byte stream and persisted to a database. I any get the byte stream back, but how do I convert it into an xml file again?
I have a web forms web application (asp.net 2.0). When the user submits the form I have the submit link actually going away so they can't submit it again. However, they could press F5 and that is causing another insert into the database, which I don't want to have happen.
Is there a setting of some sort that I can set if/when they do press F5 to tell the page - don't submit again?
How convert a string into a ActiveSupport::TimeWithZone? My dilemma is this. I need to update a field (called updated_at). The field in mysql is datetime, and the class is ActiveSupport::TimeWithZone. But the dates are strings like "10/17/2008". I used "10/17/2008".to_date (And I intend .to_time and to_datetime), and even if in console the ActiveRecord class save succesfully, the field in the database still is the current date...
Thanks in advanced.

We are planning to use BDC to read and probably write to a SQL Server content database on external server. I have heard that there are many security issues that you may run into or should be aware of before setting up BDC.
has anyone faced or knows any security issues with BDC. Thanks.
To test if i can connect to my database, I execute the following code :
using (SqlConnection connection = new SqlConnection(myConnectionString))
{
try
{
connection.Open();
canConnect = true;
}
catch (SqlException) { }
}
This works except it throws an exception if the connection failed. Is there any other way to test a Sql connection that doesn't throw an exception ?
Edit :
To add precision, i'm asking if there is a simple method that does that without having to open the connection and catch exceptions that can occur
From within TFS 2008, is there a way to view the disk space taken up on the server by a project (or by all projects)? Or is this something that can only be done by looking directly at the underlying database?
I have a PHP redirect page to track clicks on links. Basically it does:
- get url from $_GET
- connect to database
- create row for url, or update with 1 hit if it exists
- redirect browser to url using Location: header
I was wondering if it's possible to send the redirect to the client first, so it can get on with it's job, and then log the click. Would simply switching things around work?
Hi, I am learning python for a while, now I like to learn python for web, using python as a back-end of website. where and how do I start learning this:

According to wikipedia!
http://en.wikipedia.org/wiki/ORDBMS
IBM's DB2, Oracle database, and
Microsoft SQL Server, make claims to
support this technology and do so with
varying degrees of success
So, are these products true "ORDBMS" like PostgreSQL? or they are they are long way from it? can someone plz! point me to any link where i can read about the features still to be implemented by these RDBMS to become true ORDBMS!

I have a Pylons project and a SQLAlchemy model that implements schema qualified tables:
class Hockey(Base):
__tablename__ = "hockey"
__table_args__ = {'schema':'winter'}
hockey_id = sa.Column(sa.types.Integer, sa.Sequence('score_id_seq', optional=True), primary_key=True)
baseball_id = sa.Column(sa.types.Integer, sa.ForeignKey('summer.baseball.baseball_id'))
This code works great with Postgresql but fails when using SQLite on table and foreign key names (due to SQLite's lack of schema support)
sqlalchemy.exc.OperationalError: (OperationalError) unknown database "winter" 'PRAGMA "winter".table_info("hockey")' ()
I'd like to continue using SQLite for dev and testing.
Is there a way of have this fail gracefully on SQLite?

Originally posted on Server Fault, where it was suggested this question might better asked here.
We are using JBoss to run two of our WARs. One is our web app, the other is our web service. The web app accesses a database on another machine and makes requests to the web service. The web service makes JMS requests to other machines, aggregates the data, and returns it.
At our biggest client, about once a month the JBoss Java process takes 100% of all CPUs. The machine running JBoss has 8 CPUs. Our web app is still accessible during this time, however pages take about 3 minutes to load. Restarting JBoss restores everything to normal.
The database machine and all the other machines are fine, only the machine running JBoss is affected. Memory usage is normal. Network utilization is normal. There are no suspect error messages in the JBoss logs.
I have set up a test environment as close as possible to the client's production environment and I've done load testing with as much as 2x the number of concurrent users. I have not gotten my test environment to replicate the problem.
Where do we go from here? How can we narrow down the problem?
Currently the only plan we have is to wait until the problem occurs in production on its own, then do some debugging to determine the cause. So far people have just restarted JBoss when the problem occurred to minimize down time. Next time it happens they will get a developer to take a look. The question is, next time it happens, what can be done to determine the cause?
We could setup a separate JBoss instance on the same box and install the web app separately from the web service. This way when the problem next occurs we will know which WAR has the problem (assuming it is our code). This doesn't narrow it down much though.
Should I enable JMX remote? This way the next time the problem occurs I can connect with VisualVM and see which threads are taking the CPU and what the hell they are doing. However, is there a significant down side to enabling JMX remote in a production environment?
Is there another way to see what threads are eating the CPU and to get a stacktrace to see what they are doing?
Any other ideas?
Thanks!

Hi,
I'm in the process of building an app related to healthcare IT. My company wants to be able to distribute it through the appstore, but only if a device identified by the UDID of is specifically provisioned in the database. I've got all that built, but I was wondering if Apple might reject something like this.
Has anyone had any experience with activation codes?
Thanks,

I have a variable, emailBody, which is set to a string stored in a database
emailBody = DLookup("emailBody", "listAdditions", "Id = " & itemType)
The string icludes an IIf function (which includes a dlookup function).
?emailBody
The new commodity is" & Iif(dlookup("IsVague", "CommodityType", "Description= " & newItem)="1", "vague.", "not vague.")
How do I properly format the string so that the function will be evaluated and the result stored in the string?
I'm in the process of writing a small asp.net mvc application that is using the northwind.mdf. When building the solution I get this error:

Order is a table in the northwind database.
any help is most appreciated.
Hi
I would like to get the contents of my FB app's wall into my iPhone app. The contents on the wall are directly posted there by me and not obtained from any database.
Can someone please point me to the documentation where I can get the information for accessing these messages/their comments from my iPhone app?
I searched on the Facebook wiki, but it takes me to the github page for FB-Connect on iPhone, nothing where I can see all the API calls possible.
Thanks.
