RoR and Blojsom and more Web 2.0 Apps on Sun Web Server

Thu, 02 Nov 2006 17:32:44 -0800

Sun's WebServer 7.0 provides a Java Web Tier as well as good connectivity (NSAPI, Fast-CGI) with many non-Java applications. As an example of the former, Seema also shows how to run Blojsom, which follows from Blojsom on GlassFish, as did our previously reported Phobos on Web Server. As an example of the latter, Seema describes in detail how to Run Ruby On Rails.

All together, the Sun WebServer is a good Web 2.0 Platform, and it will get better as one will be able to run the latest Java Web Tier by Plugging the GlassFish Web Tier.

Plugging the GlassFish Web Tier into Sun Web Server 7.0

Thu, 02 Nov 2006 06:27:54 -0800

One of my favorite quotes says: "In theory there is no difference between theory and practice. In practice there is." (Yogi Berra or Jan_L._A._van_de_Snepscheut). In theory, we knew that we could plug in the GlassFish Web Tier into Sun's Web Server 7.0. And now Krishnamohan shows that there is practice to back it out!

This means that you will be able to run your Web Tier apps from GlassFish in your Web Server. Plus all the benefits from the Sun Web Server. Good news all along.

Thanks to CVR for the tip.

Waiter! There is a TCL in my Server!

Wed, 25 Oct 2006 08:27:32 -0700

Did you know that there is a TCL interpreter in Sun's Web Server 7.0? And it is put to good use, as shown by True Blue in this collection of detailed blog entries on WADM, starting with why TCL was chosen (this was way before jRuby came into focus at Sun), going through parts II (global variables), III (ACL), IV (log analyzer), V (access to Java objects), VI (parsing httpd.config), VII (faking a file system), and the last - so far - VIII (extensions).

I could not find a concise quote for the Monty Python eurojoke, but here is one set of fly-in-the-soup jokes.

Yes, you can run Java EE 5 web tier on Web Server 7.0 today!

Official Support for Apache in GlassFish?

Mon, 16 Oct 2006 23:33:04 -0700

It seems quite a number of people are using GlassFish with the Apache HTTP Server, so a natural question, which Jean-Francois is asking is whether we should Formalize the Support. Your comments would be appreciated.

Added: Be sure to check the "mail thread. People are reporting success with mod_jk and mod_proxy_ajp for Apache, isapi_redirect.dll for IIS and nsapi_redirect.dll for iPlanet and Sun One web server.

Improved Virtual Hosts (Servers) Support in GlassFish V2

Mon, 16 Oct 2006 09:33:15 -0700

Virtual hosts (or servers) are very popular and GlassFish supports them (see SJS AS 9.0 Doc Book). The support for virtual hosts has been improving in GF V2 and early in the cycle Jean-Francois explained how to Dynamically Add them. Now Jan explains the concept of a virtual server docroot and the new flexible mechanisms in the latest builds

Check Jan's blog for details. The SJS AS 9.0 docbook has a good chapter on this topic; just note that it uses the term "virtual server" instead of "virtual host" and "http-listener" instead of "connector".

Nonblocking SSL support now in Grizzly

Wed, 27 Sep 2006 11:18:53 -0700

Jean-Francois writes another informative article this time on adding SSL to Grizzly which uses NIO. This means that he is adding SSL over a framework that uses NIO SocketChannel (non-blocking) implementation. As he comments, SSL support has been in GlassFish since it's inception but that uses the blocking socket method. He goes over the obsticles that he faced and the solutions he came up with.

He did say it was a bit like riding your bike in the snow. Doable but hard...

Extension in Web Tier of GlassFish

Mon, 11 Sep 2006 12:17:00 -0700

The web tier of GlassFish is based on the Catalina architecture (from Tomcat 4.0) that provides a number of extension points. These extensions are implementation-specific but they are sometimes indispensable. Jean-Francois's latest entry provides an overview of the different extension points, check it out.

The mechanism for adding the extensions is very easy, starting with GlassFish V2 b17, which will be part of Milestone 2, later this month.

Grizzly framework bundle now available

Fri, 01 Sep 2006 17:49:54 -0700

After many requests from users, Jean-Francois posted the Grizzly Framework in the maven repository on java.net. Included with the framework classes is a basic example. See Jean-Francois' blog for more info.

Jean-Francois is currently working on enhancements to Grizzly as part of GlassFish V2 release and is asking for feedback. See his post on the GlassFish forum for more info.

How To: Web Services, Web Server 7.0 and NetBeans 5.0

Thu, 31 Aug 2006 05:51:29 -0700

The Sun Java System Web Server 7.0 Technology Preview release was announced here during JavaOne. It has many cool features that will be of interest to Java developers.

Krishna and Marina have published a nice how-to on building and deploying web services to Web Server 7.0 using NetBeans 5.0. Check the article out.

Jetty has integrated the JSP compiler from Project GlassFish

Thu, 24 Aug 2006 16:50:56 -0700

Jan reports that Jetty Has Integrated the GlassFish JSP compiler and it has nice things to say about us.

The GlassFish Team is actively supporting this reuse, typical of open source projects (see DTrace in Leopard) and it factored out the JSP compiler to make it possible to Use the JDT Compiler in JSP compilations. I expect more cross-project sharing / recombinations in the future.

Added: Also check out Jan (Bartel)'s blog.

Configuring your WebApp Class Path in GlassFish V2

Sat, 12 Aug 2006 22:07:13 -0700

Jan is reporting a change in the interpretation of relative paths in sun-web.xml, the implementation-specific configuration file for GlassFish. Starting with GF V2 b12, relative paths in the extra-class-path attribute of the class-loader element will be interpreted relative to the WebApps context root.

Check Jan's Blog for furter pointers.

Even Faster! JSP Compilation with Mustang and GlassFish

Tue, 01 Aug 2006 09:05:39 -0700

Most JSP implementations translate a JSP file into a Java source file and then compile it, which means that Java compilation speed is a key factor in the JSP development experience. Recently Jan reported on how to use the JDT Compiler to get a substantial improvement but Kin-Man now reports even Better Results.

Kin-Man updated the JSP GlassFish compiler to dynamically use the JSR-199 APIs when running on Mustang so it can bypass both ant and the file system. The results are very good: JSP compilation is around 10x faster and the JSP test-suite is now running 3.5x times faster!

This is already checked into GlassFish V2 and will be in the next promotion b11, and in the first milestone. And Kin-Man also has further improvements to try out...

Using Eclipse's JDT Compiler in Project GlassFish

Sat, 29 Jul 2006 10:05:24 -0700

Tomcat 5.5 by default uses the Eclipse JDT Compiler instead of the javac from Sun's SDK and one of the requests on Project GlassFish has been to be able to use JDT for JSP compilation. Jan just modified Jasper to accomplish this; read the instructions from Jan's Blog Entry.

BTW, Kin-Man is, separatedly, working on allowing Jasper to use the Mustang standard javac API, which should give substantial performance improvements; stay tuned.

NetBeans Plug-In for Sun Web Server

Sat, 29 Jul 2006 10:05:23 -0700

There is now a NetBeans 5.0 Plug-In to develop, deploy and debug WebApps onto Sun's WebServer 7.0 Technology Preview. Mukesh and Marina's article shows How to Use the Plug-In , just note that the article was posted two weeks ago and it refers to the original TP, but TP2 was released yesterday.

The Java Web-Tier implementation used in Sun's WebServer 7.0 is from SJS AS 8.2 (based on J2EE 1.4) to match the rest of the Java Enterprise System, but WS 7.x has been designed to allow a quick rev into the Java EE 5 versions of these specifications (In contrast, WS 7.0 already includes JAX-WS 2.0).

For more information, check: Product Page, the Web Server hub at SDN, NetBeans' Web Server home page and the WS Forum.

Running AsyncWeb in GlassFish

Fri, 21 Jul 2006 16:25:56 -0700

Jean-Francois reports that AsynchWeb (a non-blocking Java HTTP Engine) can now be deployed on top of Glassfish. The installation steps are a little raw at the moment but JF hopes to improve the experience.

If you are going to be at OSCON 2006 in Portland next week you can find out more about high-performance, non-blocking IO and it's importance to Web Services.

NIO Selector pooling in Grizzly

Thu, 20 Jul 2006 10:58:49 -0700

Jean-François's latest "Tricks and Tips with NIO" article shares advice (and code) for pooling Selectors to improve scalabilty when handling network requests - a feature used in GlassFish's Grizzly HTTP Listener.

If you missed the previous articles in the series, here they are - Part I, II and III.

JSF 1.2_01 is out...

Thu, 20 Jul 2006 10:58:47 -0700

Ryan reports that JSF 1.2_01 is Now Available. This is a patch release that contains bug fixes as well as new features; check the Release Notes. The implementation is available as a separate download but you probably want to wait for it to show in the next integrations from Project GlassFish, which have been temporarily delayed.
