J2EE

This blog highlights some of the changes that are part of GlassFish v3 logging.  Since Prelude I have added 3 asadmin commands related to logging. I have updated the set-log-level command and changed the syntax. See below for details. The new commands are:     * asadmin rotate-log     * asadmin list-logger-levels     * asadmin set-log-level...

I've had a few requests on how to write a busy status indicator - you know, the little spinning ball that's there while an Ajax call is active, and which goes away once the request is complete. So, I spent about two hours today, and did just that - including putting it into a component so it's reusable. As usual, it involved no Java, and only a minimal amount of JavaScript. First, I needed...

A few weeks ago, I blogged about ways to execute scripts on the client which you were writing out from the server via Ajax.  By popular demand, the latest build of Mojarra now allows execution of inline scripts. So, instead of having to either bundle code into an <eval> tag, or using an event to execute it later, you can now simply say something like: <script type="text/...

High availability in SailFin can be achieved by deploying a cluster of instances and configuring the load balancer and the replication modules as per the user's needs. Apart from the basic configuration of these modules, SailFin (2.0) also allows users to separate the intra-cluster traffic (resulting from the load-balancer, replication and the group management service modules) from the external...

I am one of the people selected for FishCAT, so let me know what some of the bugs are you think are irritating ;) Or what you think the new version of Glassfish should contain. Or if you already have played around with Glassfish V3 builds, just let me know what worked or did not work for you!

Databases

TOTD #97 showed how to install GlassFish Tools Bundle for Eclipse 1.1. Basically there are two options - either install Eclipse 3.4.2 with WTP and pre-bundled/configured with GlassFish v2/v3, MySQL JDBC driver and other features. Or if you are using Eclipse 3.5, then you can install the plug-in separately and get most of the functionality. TOTD #98 showed how to create a simple Metro/JAX-WS...

Eclipse

Now that you've installed GlassFish Tools Bundle for Eclipse 1.1, lets use this bundle to create a simple Metro/JAX-WS compliant Web service and deploy on GlassFish. These steps will work with either Eclipse 3.4.2 or 3.5 with WTP Java EE support. Lets create a simple "Dynamic Web Project" as shown below: Name the project "HelloMetro" and take all other defaults: Click on "Finish" to...

Security

The Java KeyStore API supports multiple keystore formats which include JKS( the default Java KeyStore), PKCS12, PKCS11 etc. By default when GlassFish V3 is installed the default Keystore Type is JKS and the server keystore (keystore.jks) is located in the domain config directory.  With latest GlassFish V3 builds it should be possible to define a different KeyStore Type such as PKCS11 or...

In my last blog entry, I went over getting a YUI widget working on JSF2. This time, let's go over what's required to move that widget into a JSF component. No Java required, but a fair bit of JavaScript. In a lot of ways, this is just like other components that I've written about. The tricks are much the same - saving values into a JavaScript context. Including scripts into the component,...

There is a waiting list for people who...

OSGi

Starting with build #56, GlassFish v3 now comes pre-installed with Apache Felix Service Component Runtime, which is an implementation of OSGi Declarative Service Specification. This bundle is located in modules/ directory and is started automatically when server starts.

In a previous blog, I had shown how one could use Apache Felix Remote Shell to connect to GlassFish and administer the underlying OSGi runtime. Since, GlassFish installs some 100 odd bundles, it is not very easy to explore them using the shell. There are some improvements planned for Felix shell to address this issues, but then there are a lot of people who are just comfortable with GUI as...

Long story short: telnet "host running glassfish v3" 6666 -> help Welcome to my blog. It's been a while since I last wrote something here. The last few months (or is it a year now) have been quite challenging for us at GlassFish project. Most of my time has been spent in making sure that GlassFish v3 runs on OSGi and runs well. We have made a lot of progress in this regard and made...

Accessibility

A few days back, Jerome blogged about how to deploy OSGi bundles in GlassFish using "asadmin deploy --type=osgi" command. In his blog, he also mentioned why you should not copy your bundles to glassfish/modules directory. In this blog, I will talk about a filesystem based management agent that I have integrated in GlassFish and how you can take advantage of the same. We have...
