SVN on Mac OS X in 10 steps.

2011-02-14T15:23:00.000-08:00

1. Download Subversion DMG from
2. Setup Subversion
3. $ sudo mkdir /usr/local/svn
$ sudo svnadmin create /usr/local/svn/[PROJECT_NAME]
$ sudo chown -R www /usr/local/svn
4. Create httpd.conf on the base of content of /etc/apache2/httpd.conf
5. Add to LoadModule section

LoadModule dav_svn_module libexec/apache2/mod_dav_svn.so

At end of the file, add this include

Include /private/etc/apache2/extra/httpd-svn.conf

Copy edited file to /etc/apache2/httpd.conf, overwrite
6. Create /etc/apache2/extra/httpd-svn.conf with following content:

<Location /svn>
DAV svn
SVNParentPath /usr/local/svn

# how to authenticate a user
AuthType Basic
AuthName "Subversion repository"
AuthUserFile /etc/apache2/subversion.auth
# only authenticated users may access the repository
Require valid-user

</Location>

7. $ sudo htpasswd -cm /etc/apache2/subversion.auth [USER_NAME] and create password for the user
8. Stop and start Apache server using apachectl or by un-checking and checking the Web Sharing checkbox in System Preferences > Sharing.
9. To access SVN, the URL is http://localhost/svn/[PROJECT_NAME]. The configuration is using SVN ParentPath configuration which means that you can have multiple repositories in /usr/local/svn (e.g. project1, project2, etc)
10. Setup SVN in Eclipse/STS, type following path: http://localhost/svn/[PROJECT_NAME], enter [USER_NAME] credentials.

GWT + Roo + MySQL: Special & Cyrillic characters in UTF8

2011-02-03T11:28:00.000-08:00

Defaut app generated by Roo persisting special & Cyrillic characters not correctly, as '???'. To fix that, update generated database.properties file:

database.url=jdbc\:mysql\://localhost\:3306/[YOUR_DB_NAME]?autoReconnect\=true&useUnicode\=true&characterEncoding\=UTF-8

GWT. Collection fields

2011-02-03T07:43:00.000-08:00

For example, you have something like:

@Entity
public class Contact {
...
@OneToMany(mappedBy="contact", targetEntity=Tag.class, fetch=FetchType.EAGER)
private List tags;
...
}

On first look, when you fetching contacts, their 'tags' fields should be already prepopulated... as they annotated as eager... But then you'll try to execute something like:

requestFactory.contactRequest().findAllContacts().fire(lastDataReceiver);

all 'tags' will be NULL.

To fetch collection fields together with parent entity you have to use:

requestFactory.contactRequest().findAllContacts().with("tags").fire(lastDataReceiver);

Spring ROO + GWT. Back-end.

2011-02-03T06:40:00.000-08:00

Playing with Spring Roo and GWT 2.1.1 plugin... Sometimes like it, sometimes - not. It's a long story, I'll concentrate on some tricky points...

It was not clear for me, how they implementing back-end stuff, as there are no any code in entity classes, as it usually appears in GWT examples. I found what Roo generates all back-end as AspectJ classes paced into same package as an entity. They are Roo-managed and not intended to be modified... If you need some special methods, you may create them in the entity class, Roo will not overwrite your code.

The tricky point - STS hide such files, .aj, by default. To show them, go to drop-down menu in Package Explorer in STS -> Filters... -> uncheck "Hide generated Spring Roo ITDs".

It's now about 4.26 am local time... I've been traveling for last 10 hours with a connection at "Vnukovo" airport, Moscow...

Oh my... I could write a book about this trip... will start tomorrow :)

For now I could say just one thing: I've NEVER EVER EVER spent a 130 roubles (~$4) for a trip from an airport to a city center :)

Setup Tomcat on Mac OS X

2010-10-30T01:50:00.000-07:00

How to develop Java EE applications on MacOS X? Eclipse + Tomcat is a good setup. You may download Eclipse from eclipse.org, just extract it to the folder you want. Tomcat setup a bit complicated...

1. Download latest binaries: Tomcat 7.0
2. Extract it to /Library/Tomcat
3. Lunch Terminal
4. cd /Library/Tomcat/bin
5. chmod 777 *.sh
6. Start it via ./startup.sh and kill it by ./shutdown.sh
7. Setup server configuration in Eclipse.

Enjoy! :)

Back to the future? Forward to the past!

2010-10-16T14:34:00.000-07:00

Hi folks! I'm back... Here I'm starting a new blog about Russia and my new life :)
It's pretty clear to me, what peoples around "had me" with my blog and all my thoughts about Russia, so, I've started it for you and all my friends around the world :) It means, it will be written in english... mostly :)

I spent a lot of hours during last few days in NY trying to create a name for my new blog... I was overhelmed by positive experience and thoughts about my future and "Back to the future" looked like a no brainer...

Now I'm in Russia for a week... and some of my thoughts have changed dramatically... :) So, I decide to change the name the same way... from "Back to the future" to "Forward to the past!", cause moving back to Russia from US like a huge downshifting and relocation from the era of space flights to the Stone age. :) By that name I just want to point out the place of this country among other european countries and US, nothing personal :)

I'm still trying to think positive... "Stone age" means somebody have a chance to bring it closer to other world :), but even thinking this way in Russia require a lot of extra energy :)

See ya! :)
