String setSearchString(searchString) { def xml = proxy.GetSpeech(searchString) def XmlParser parser = new XmlParser() def speech = parser.parseText (xml) "PLAY: " + speech.PLAY.text() + "\nSPEAKER:" + speech.SPEAKER.text() + "\nTEXT:" + speech.text() }

In Java, new lines need to be closed with a quote and contain the "+" character. In Groovy, although the above is perfectly acceptable, one can use triple-quotes for multi-lines. Even nicer, in this case, is to use GStrings (expressions declared inside double-quotes), together with Expandos (dynamic collections), instead:

String setSearchString(searchString) { def xml = proxy.GetSpeech(searchString)
    def XmlParser parser = new XmlParser() def speech = parser.parseText (xml) Expando result = new Expando() result.play = "PLAY: ${speech.PLAY.text()}" result.speaker = "SPEAKER: ${speech.SPEAKER.text()}" result.text = "TEXT: ${speech.text()}" result.all = "$result.play\n$result.speaker\n$result.text" }

Much neater, more readable, and the result is the same as before. Plus, it could probably be improved even further.

Some progress, at last. Quite some of my (spare?) time the last couple of weeks I spent pondering a smart way of getting an existing Spring/webapp environment consisting of several modules migrated to make more use of the Java EE 5 features, namely provided by the glassfish application server which has been in productive use in our environment for quite a while now. But while migrating webapps from tomcat to glassfish has proven to be pretty straightforward in our case (asides a few minor caveats it was just as difficult as deploying the .war file using asadmin and seeing the application start up on the new system… ;) ), the idea to make our “backend” application (so far Spring-Remoting packed into a web application context) a well-behaving EJB3 module turned out to be a little more complex than just that. But doable, to say now, after all…

   and click on the green button to run the query as shown here:
   
   
   
   
   
   
6. Following the same instructions, populate the table using the following SQL:
   
   
   
   

   INSERT INTO STATES VALUES (1, "AL", "Alabama"); INSERT INTO STATES VALUES (2, "AK", "Alaska"); INSERT INTO STATES VALUES (3, "AZ", "Arizona"); INSERT INTO STATES VALUES (4, "AR", "Arkansas"); INSERT INTO STATES VALUES (5, "CA", "California"); INSERT INTO STATES VALUES (6, "CO", "Colorado"); INSERT INTO STATES VALUES (7, "CT", "Connecticut"); INSERT INTO STATES VALUES (8, "DE", "Delaware"); INSERT INTO STATES VALUES (9, "GL", "Florida"); INSERT INTO STATES VALUES (10, "GA", "Georgia"); INSERT INTO STATES VALUES (11, "HI", "Hawaii"); INSERT INTO STATES VALUES (12, "ID", "Idaho"); INSERT INTO STATES VALUES (13, "IL", "Illinois"); INSERT INTO STATES VALUES (14, "IN", "Indiana"); INSERT INTO STATES VALUES (15, "IA", "Iowa"); INSERT INTO STATES VALUES (16, "KS", "Kansas"); INSERT INTO STATES VALUES (17, "KY", "Kentucky"); INSERT INTO STATES VALUES (18, "LA", "Louisiana"); INSERT INTO STATES VALUES (19, "ME", "Maine"); INSERT INTO STATES VALUES (20, "MD", "Maryland"); INSERT INTO STATES VALUES (21, "MA", "Massachussetts"); INSERT INTO STATES VALUES (22, "MI", "Michigan"); INSERT INTO STATES VALUES (23, "MN", "Minnesota"); INSERT INTO STATES VALUES (24, "MS", "Mississippi"); INSERT INTO STATES VALUES (25, "MO", "Missouri"); INSERT INTO STATES VALUES (26, "MT", "Montana"); INSERT INTO STATES VALUES (27, "NE", "Nebraska"); INSERT INTO STATES VALUES (28, "NV", "Nevada"); INSERT INTO STATES VALUES (29, "NH", "New Hampshire"); INSERT INTO STATES VALUES (30, "NJ", "New Jersey"); INSERT INTO STATES VALUES (31, "NM", "New Mexico"); INSERT INTO STATES VALUES (32, "NY", "New York"); INSERT INTO STATES VALUES (33, "NC", "North Carolina"); INSERT INTO STATES VALUES (34, "ND", "North Dakota"); INSERT INTO STATES VALUES (35, "OH", "Ohio"); INSERT INTO STATES VALUES (36, "OK", "Oklahoma"); INSERT INTO STATES VALUES (37, "OR", "Orgeon"); INSERT INTO STATES VALUES (38, "PA", "Pennsylvania"); INSERT INTO STATES VALUES (39, "RI", "Rhode Island"); INSERT INTO STATES VALUES (40, "SC", "South Carolina"); INSERT INTO STATES VALUES (41, "SD", "South Dakota"); INSERT INTO STATES VALUES (42, "TN", "Tennessee"); INSERT INTO STATES VALUES (43, "TX", "Texas"); INSERT INTO STATES VALUES (44, "UT", "Utah"); INSERT INTO STATES VALUES (45, "VT", "Vermont"); INSERT INTO STATES VALUES (46, "VA", "Virginia"); INSERT INTO STATES VALUES (47, "WA", "Washington"); INSERT INTO STATES VALUES (48, "WV", "West Virignia"); INSERT INTO STATES VALUES (49, "WI", "Wisconsin"); INSERT INTO STATES VALUES (50, "WY", "Wyoming");

3. Create and configure the persistence unit
1. Right-click on the newly created project and select "New", "Entity Classes from Database ..." as shown:
   
   
   
   
   
   
2. In DataSource, select "New Data Source..." and enter the JNDI name "jndi/states" as shown:
   
   
   
   
   
   
3. Select "STATES" table in "Available Tables:" and click on "Add >" and then "Next >".
4. Click on "Create Persistence Unit ...", take all the defaults and click on "Create".
5. Enter the package name as "server" and click on "Finish".
6. Expand "Configuration File", open "persistence.xml". Unselect "Include All Entity Classes" check box, click on "Add Class...", select "server.States" and click on OK. The updated view looks like:
   
   
   
   
7. Select the XML view and replace <properties/> with
   
   
   
   

   <properties>         <property name="toplink.jdbc.user" value="duke"/>         <property name="toplink.jdbc.password" value="duke"/>     </properties>

   
   
   The username and password values must match the ones specified during database creation. The updated "persistence.xml" looks like:
   
   
   
   

   <?xml version="1.0" encoding="UTF-8"?> <persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">   <persistence-unit name="AutocompletePU" transaction-type="JTA">     <jta-data-source>jndi/states</jta-data-source>     <class>server.States</class>     <exclude-unlisted-classes>true</exclude-unlisted-classes>     <properties>       <property name="toplink.jdbc.user" value="duke"/>       <property name="toplink.jdbc.password" value="duke"/>     </properties>   </persistence-unit> </persistence>

4. Create a Servlet to perform the database operations
1. Right-click on the project, select "New", "Servlet".
2. Enter the class name as "StatesServlet" and package as "server" and click on "Finish".
3. Add the following fragment in the beginning of the class:
   
   
   
   

   EntityManager em;     @Override     public void init() throws ServletException {         EntityManagerFactory emf = Persistence.createEntityManagerFactory("AutocompletePU");         em = emf.createEntityManager();     }

4. Replace the commented code in "processRequest" with the following fragment:
   
   
   
   

   String abbrev = request.getParameter("abbrev");             List<States> list = em.createNamedQuery("States.findByAbbrev").                     setParameter("abbrev", abbrev).                     getResultList();             if (list.size() > 0) {                 States s = list.get(0);                 out.println("Found " + s.getName() + " with abbrev \"" + abbrev + "\"");             } else {                 out.println("No matching state found with \"" + abbrev + "\"");             }

   
   
   and fix the imports by right-clicking in editor pane and selecting "Fix Imports".
5. Right-click on the project and select "Undeploy and Deploy".

We announced WebSynergy at JavaOne; we were expecting to launch the public site with transparent builds shortly after that but the end of (our fiscal) year and the summer have slowed us down. I think we will soon be able to show public progress; in the meantime we are making internal progress, together with the Liferay team and with add-ons.

As an example of the type of synergy across our projects, Ajit describes how to Integrating WebSynergy with OpenSSO on GFv3, showing how to download and assemble the pieces and how to configure OpenSSO. Of course, the actual Sun product would come with good ease-of-use for all these, and other, pieces.

The first start/installation of JFtp (see screenshot) via WebStart takes about 10-20 seconds. All subsequent starts about 5 seconds - (on Java 6u10). Another great sample for WebStart, Swing and Java 6u10 combo.

Btw. it is a Ftp, Http, Ssh, SMB etc. client :-).

Ming is in charge of the localization efforts for the GlassFish Server and she is soliciting input on Expansion of Language Support. GlassFish is currently localized to Simplified Chinese, Traditional Chinese, Japanese, Korean, French, German, and Spanish - see TA entry and G11n Home Page. The process will be further simplified and opened for participation for GFv3 and GFv2.1.

If you are interested in helping, please contact Ming or post directly to the G11N mailing list at glassfish.dev.java.net.

I just noticed that Glen has started working on a Grails in Action book that looks very interesting. While working on that, he is collecting good tips like Grails and JNDI Data Sources in GlassFish. Grails continues to gain adoption (Google Trend), leveraging the strengths of the language and framework and its easy integration into the Java plaform.

NetBeans is investing to be a top IDE for Grails, see Grails Plugin for NetBeans and Integrating Meera with Grails and NetBeans, and the responses so far are very positive. All this targeted for NetBeans 6.5; I think the result will be a top IDE for dynamic languages.

Even IBM's DeveloperWorks is covering Grails, their Mastering Grails Series includes 7 articles, from Introduction to Grails to Grails and Legacy DataBases. I've skimmed the articles and they look good. Their list of AppServers "somehow" does not include GlassFish server, but don't be distracted - it should work, and if they don't, it's a bug we will fix :-)

Related entries at TheAquarium can be found via tags: Grails or Scripting.

As shown yesterday, the Groovy method shown above is called from the button in the form, that you see deployed in the screenshot above. On the return of the XML, Groovy takes a tiny number of lines to break up the payload and then (without the "return" statement being necessary, as pointed out in the comments yesterday by Alex Tkachman) is returned to the Swing form.

If you need to break the 2GB or 4GB heap maximum barrier for your GlassFish-powered application, you can move to a 64-bit JVM. The topic of 64-bit JVM was touched upon here when GlassFish v2 was released. What wasn't explained is what configuration steps it takes. A recent thread on the GlassFish forum pointed out that this wasn't well documented or at least easily accessible. This FAQ entry on the Wiki tries to fix this. Once you're set with the 64-bit JVM, the GlassFish Performance and Tuning Guide can come handy.

Let us know when you feel important questions are not well documented on the GlassFish wiki FAQ or on the product documentation. You can either add it yourself to the wiki or send us a ping on the Forum. Thanks!

The Tasktop Team is very pleased to announce the release of Tasktop Summer 2008. Summer is a great time to offload your brain, so we’ve packed this release with features that will help you do just that. This release’s splash screen commemorates a summer hike in the mountains overlooking Vancouver.

The coolest thing in this release is the new time tracking and reporting feature, which gives you full transparency into your work activities with automatic to-the-minute tracking of time spent working both within and outside of Eclipse. As usual, we put all of the control at your finger tips, enabling you to do things like adjusting timings. You also get flexible reports so that you don’t have to stress the creative side of your brain when needing to report activity or fill out time sheets, and can save your creativity for more interesting activities like coding. As an example, take a look at my time report for the week after the Mylyn 3.0 release, from which I can immediately see that I spent most of my time on the Tasktop working set (blue part of pie chart on far right), a bunch of time went to managing (the gray bars in the graph) and thankfully a higher proportion to working on the tasks I had scheduled (colored bars in the graph). From this I can immediately see why I was itching to write code by the end of the week, since most of my week went into non-programming activities.

Eclipse Mylyn users will be pleased to learn that we are now providing a free version of Tasktop called Tasktop Starter. This allows us to deliver to you some valuable features that are out of the scope of Eclipse and Mylyn. Below you can see a snapshot of the welcome screen that will get you started exploring the features in Tasktop Starter, such as one-click install of partner connectors, automatic Mylyn updates to either release or weekly builds, and a time tracking dashboard for the current week. We’ve also included the Gmail connector for free, which lets you easily tag conversations in Gmail have them appear in Mylyn’s Task List and be accessible when working offline. You need Tasktop Pro for the main productivity features such as focused web browsing, desktop integration, customized time reporting and additional connectors such as Microsoft Outlook. But with Tasktop Starter you get both a useful day-to-day tool and a glimpse at what it’s like to have Mylyn’s task-focused interface keep you focused and productive for the non-coding parts of your workday.

I drive at least 90% of my workday from Tasktop/Mylyn/Eclipse, and one of my favorite new features is the one-click switching of working sets. It seems so rudimentary, but this makes switching your project/work/role contexts as easy as switching task contexts. In addition, you get to see how far behind you’re getting on any particular working set, thanks to an indication of the number of incomings. This is just one part of the additional streamlining that we’re providing with Tasktop as part of our mission to save you clicks. Less is more.

We hope that you enjoy this release of Tasktop and continue sending us your feedback and votes for future enhancements and integrations. For more info see:

There’s a persistent rumor that crops up every few months about social news site Digg being acquired by ____ (insert company here). The latest, citing “multiple sources inside and outside Google”, says that Google will buy Digg for $200M. This is similar to a rumor in March that Digg was going to be acquired “soon” by Google or Microsoft or two other companies, according to “a source very close to the deal”. In 2006, it was Yahoo who was going to buy Digg for $30M, at least if you believed “two sources close to Yahoo”.

Whether the rumors turn out to be true this time or not, it’s a common pastime to imagine what the name of a merged company will be. Of course, it’s all but certain there would be no name change, and that each company or division would continue with its current name. But just for fun… what is your favorite?
