Googlebot, CookieLocaleResolver and default locale

March 2, 2011

Googlebot doesn’t set a locale on request.

What does this mean? Well, in my case when I localized http://www.uutispuro.fi, googlebot only minded about english content. Even if I made different urls and sitemaps for webmaster tools.

Why such a behaviour? I’m using Spring’s CookieLocalResolver, and ofcourse it had a default to en_US. This took a while for me to notice. Setting the default to “fi” does what I was expecting in the first place.

<bean id="localeResolver" class="org.springframework.web.servlet.i18n.CookieLocaleResolver">
  <property name="defaultLocale" value="fi"/>
</bean>

jpa + hibernate + spring + c3p0 + hibernate-search pom.xml

October 10, 2010

Maven pom.xml file for a jpa, hibernate, spring, quartz, hibernate-search app.
Versions: jpa 2, Spring 3, hibernate 3.5, hibernate-search 3.2, c3p0 0.9.1.2

I have been using this for making a rss news site. I decided to share this if someone else is struggling with getting the versions match with hibernate-search and hibernate or getting the right dependencies with c3p0.

I’m using jetty and hsqldb for developing. In production, I have lighttpd in front of jetty and the production database is mysql which I’m using.

Spring Recipes, second edition

September 22, 2010

More than a year ago I read a very good book (in my opinion at least), Spring Recipes, A Problem-Solution Approach. It had many things which I needed or wanted to try. Just excellent. Well, time has passed and the first book has shown me everything it has to offer. Time for a new good book about Spring. It seems the solution is the new second edition of Spring Recipes which I just received🙂 First of all, it has been renewed to Spring 3. It has over 1000 pages (ok, it’s quite big), but is there any other book which contains so many detailed things about Spring?


AKG K142 HD, new headphones

September 21, 2010

I just love them. Sound quality is way better than anything I’ve had until today. mp3:s are not for me (at least not the bad quality ones), not anymore.


c3p0, Spring, Hibernate and NoResultException

September 21, 2010

I was fighting for a while with NoResultException and c3p0:s config because I thought that was the problem with NoResultExceptions I got. While making uutispuro.fi I finally realized it wasn’t the source of the problem.

I had a method doing a persist and a method doing a merge which I had surrounded with try and catch … and of course with a finally block doing an em.close().

The problem was with the queries doing a .getSingleResult(). I forgot that these might throw the error in hand, and if they did, the closing of entitymanager wasn’t done.


try {
Query query = em.createQuery("select query");
return query.getSingleResult();
} catch (NoResultException e) {
log.debug(e);
} catch (Exception e) {
log.error(e);
} finally {
em.close();
}


My new 13″ MacBook Pro

September 15, 2010

Been using it for more than a month now. Just love it. Compared to the old HP, this one is from an other planet.

Ok, there is only 4GB of memory (would like to double that), but there actually isn’t anything else I would like change or add. Compared to the HP (keyboard was terrible, actually two of it’s harddrives went zeee, and it just wasn’t fun to use) this one is just fun.
