Java 7u51 is scheduled for release in January. It will have some consequences for you Forms installation that you need to address.
As far as I know there is no problems with using 7u51 on the server side, only on the client side.
7u51 requires you to sign all RIAs (Applets and Web Start applications).
Oracle already signs the standard jar (more...)
After input from Jacco H. Landlust and Edwin Biemond I have rewritten my post about entropy.
In computing you often need random numbers. They are used for encrypting stuff but also for lots of other things.
For Linux servers random numbers are default provided by the /dev/random device. /dev/random is a pool of random bits (more...)
Previously I have stated that there are some exceptions you would always want to keep an debugger breakpoint
on for. This help prevents code rotting away without you noticing - sometimes masking a different problem.
If you take this seriously then it is a good idea to extend this idea (more...)
Sometimes it would be really nice to have named method parameter in Java, this doesn't look likely for a long while but there is always another little work around, for example using a builder pattern to get similar behaviour, that will bridge the gap for a little bit. It occurred (more...)
Oracle no longer posts updates of Java SE 6 and JRockit to its public download sites.
If you have a support contract you can download new updates from MOS.
You can locate the Java SE 6 downloads in this note “All Java SE Downloads on MOS (Doc ID 1439822.1)”.
Developers are often asking me how to "version" documents with Couchbase 2.0. The short answer is: the clients and server do not expose such feature, but it is quite easy to implement.
In this article I will use a basic approach, and you will be able to extend (more...)
TL;DR: Look at the project on Github.
During my last interactions with the Couchbase community, I had the question how can I easily import my data from my current database into Couchbase. And my answer was always the same:
Take an ETL such as Talend to do it
Just write a (more...)
This is a first articles in series, where I would like to study effect of various HotSpot JVM options on duration of STW pauses associated with garbage collection.
This article will study how number of parallel threads affects duration of young collection Stop-the-World pause. HotSpot JVM has several young GC (more...)
So we are running a quite a bit of automated UI testing and we have found over a large number of concurrent test nodes that even when the Xvnc plugin has correctly started that the environment is not always ready or reliable. This blog post looks at two changes we (more...)
There are bunch of graphical tools helping you to look inside of running JVM (VisualVm and JConsole are extremely helpful). Unfortunately, some times (almost always in my case), you may find yourself in SSH console on headless server side by side with your JVM (more...)
As of PeopleTools 8.52 it is possible to use REST services for POST/GET functionality. However what do you do if you are on an older PeopleTools version, but still need to make a HTTP POST and then GET the response?
Most of the applications have to deal with "master/detail" type of data:
breweries and beer
department and employees
invoices and items
This is necessary for example to create application view like the following:
With Couchbase, and many of the document oriented databases you have different ways to deal with this, (more...)
On Linux low entropy can cause certain operations to be very slow.
SSL operations need entropy to ensure randomness. Entropy is generated by the OS when you use the keyboard, the mouse or the disk.
If an SSL operation is missing entropy it will wait until enough is generated.
When you are developing a new applications with Couchbase 2.0, you sometimes need to create view dynamically from your code. For example you may need this when you are installing your application, writing some test, or you can also use that when you are building frameworks, and wants to (more...)
Autocomplete was not working for JSF tags in my Eclipse. I googled it and finally found the solution on http://www.mkyong.com/jsf2/how-to-make-eclipse-ide-supports-jsf-2-0/
The different thing I did is; I downloaded javax.faces-2.xx.xx.jar and saved in a specific folder. Then I created a user library with this jar. I did not use “jsf-api-xxx.jar and jsf-impl-xxx.jar“.
The MySQL documentation section has always had this Topic Guides page containing links to the docs for the various MySQL Connectors -- the official database drivers for various languages and programming technologies. That is the most convenient way to get the information for each Connector in PDF form, rather than downloading the entire Ref Man PDF. For HTML, it was more of a shortcut, because
In Oracle SOA Suite you can use the EJB adapter as a reference or service in your composite applications. The EJB adapter has a flexible binding integration, there are 3 ways for integrating the remote interface with your composite.
First you have the java interface way which I described here (more...)
