The solution, however, is quite easy once you know it Figure out the total capacity of your screens:

$ xrandr -q

Add the horizontal and vertical max sizes of your screens and dive into your /etc/X11/xorg.conf and a Virtual directive to your Display sub section that accounts for the total virtual screen.

    SubSection     "Display"
        Depth       24
        #  1440+1600  900+1200
        Virtual     3040 2100
    EndSubSection

The final step is then to set tell xrandr setup your xinerama. I kick off my X session with the .xinitrc file, so I’ve put these two lines there (if you don’t use this approach, you can just type these lines manually after logging in):

xrandr  --output VGA1 --off
xrandr  --output VGA1 --right-of LVDS --pos 1440x900 --auto

And that’s it! Xinerama without the need of a closed source binary driver

    Session session = Session.getDefaultInstance(mMailProperties, null);
    MimeMessage message = new MimeMessage(session);
    String body = "body from " + getClass().getName()
      + " @" + Calendar.getInstance().getTime().toString();
    message.setContent(body, "plain/text");
    message.setRecipients(RecipientType.TO, mTo);
    message.setRecipients(RecipientType.BCC, address2 + ", " + address3);
    Transport.send(message);
  ...
  store.connect(...);
  Folder folder = store.getFolder(...);
  folder.open(Folder.READ_WRITE);
  javax.mail.Message[] allMessages = folder.getMessages();
  for (javax.mail.Message message : allMessages) {
    ...
    Address[] addresses = theMessage.getRecipients(RecipientType.BCC);

The variable ‘addresses’ now hold two entries. Note that Mailbox.get(mTo) works as you’d expect.

As you can see, its far simpler than the more “official” scripts, but it does exactly what I want it to, so I’m happy

To make it log to its own log file, this is what I did to tomcat/conf/logging.properties

# added 6localhost.org.apache.juli.FileHandler to the list of handlers

6localhost.org.apache.juli.FileHandler.level = FINE
6localhost.org.apache.juli.FileHandler.directory = /var/log/escenic
6localhost.org.apache.juli.FileHandler.prefix = solr.

org.apache.solr.level=INFO
org.apache.solr.handlers=6localhost.org.apache.juli.FileHandler

Now, I get all solr messages in /var/log/escenic/solr-2009-07-22.log. What a relief! Of course, you may want to drop the logging level to WARNING

String selectString = "select * from mytable";
List result = getHibernateTemplate().find(selectString);

and this one, and no, you woun’t get any points for pointing out that this is a better, non-deprectaed way of executing a query in Hibernate

String selectString = "select * from mytable";
Query query = getSession().createQuery(queryString);
List result = query.list();

And no to the funny part: the latter implementation makes DBUnit hang forever!

Doing a thread dump of the Maven Surefire process reveals that this part of code is hanging:

"main" prio=10 tid=0x09945c00 nid=0x5279 in Object.wait() [0xb7d74000..0xb7d751f8]

	at org.apache.commons.dbcp.BasicDataSource.getConnection(BasicDataSource.java:540)

Now, who can tell me why this is?

It turned out that if you set the system user password to ‘admin’, you cannot log in! What kind of headless logic is that?!! And of course, there’s no way to re-set the admin password, so I had to re-install the DB to try a new password.

# apt-get --purge delete oracle-xe
# apt-get install oracle-xe

So, after setting the following in my .bashrc, I can enjoy (developer version of) Oracle 10.2.0.1.0 with less installation fuss than normal

Hibernate has added a complex, sorry “rich”, API on top of JDBC to construct queries and the like (in addition to OR mapping and I’m sure a host of other tings). Now, most tutorials out there are mere Micky Mouse examples and not that useful for what I need right now: joining three (maybe four tables) and returning an entity (and yes, I do know that joining many tables is expensive).

I’ve joined two tables before using one DetachedCriteria & Criteria and I assume I then can do a three table join by using two DetachedCriterias? Maybe, have to try this later. Matter of fact is that the API to construct queries is so complex, create so long code lines and so many of them, that I ventured into doing this using Hibernate’s own SQL dialect.

Of course, I believe it’s doable but I couldn’t find any good examples out there on doing it, I got this Array (or something) of java.lang.Objects rather than my nicely mapped Hibernate entity when I executed my Query object.

Object thing=[[Ljava.lang.Object;@956b74]

I didn’t see any good way of manipulating this Object thing, so I ventured lower down the food chain to the native SQL support in Hibernate:

SQLQuery query = Session.createSQLQuery(String);

Thanks to this one and setting the return entity, with the alias I used in the SQL String:

query.addEntity("b", Blue.class);

I finally got this thing working.

Now, to all of the Hibernate enthusiasts out there; if there’s a beautiful way of joining three tables returning an entity using the high level Hibernate API, I love to hear about it. But for now, I’m happy with my Hibernate/native SQL solution

Hopefully, these quotes can be of use to others too

I then learned about compacting folders:

which has made it a lot faster (and doesn’t consume 90% CPU). However, it still freezes for a couple of seconds every 5-10 minutes …
