New Web Application, Spring v2.5, changed default dispatcher to ‘springapp’

created a custom landing page – edit web.xml welcome page to make it the default.

Look at the springapp-servlet.xml and the indexController.

class="org.springframework.web.servlet.mvc.ParameterizableViewController"
p:viewName="index" />

Looking around on the internet it seems this may have been around for a while, so I was mystified as to why I hadn’t come across it before. However it seems like the kind of bug which stops occuring when I create my new Spring Web Application with another project already open in the Project Group. Don’t ask me why, and this may change in the future – but if you’re stuck on this it may be worth a try.

However one issue I came across trying to get going with it was just the installation instructions. I ran the ‘apt-get install libcatalyst-perl’ command, but following this wasn’t enough to get the initial example up and running.

The error obtained was ‘Can’t locate Catalyst/Plugin/Static/Simple’ in @INC.

The fix was to also install libcatalyst-modules-perl. If you list all the catalyst packages you may also see some others you like.

I’ve ordered this book which seems to get good ratings….will see how it goes…. The Definitive Guide to Catalyst: Writing Extendable, Scalable and Maintainable Perl-Based Web Applications (Expert’s Voice in Web Development)

ADDENDUM – the book turned out to be a bit useless. For instance when it came to some out of date features – for example, a third party library that even the libraries author says DO NOT USE – the book just says – yeah, this example may not work.

The best source I found was the Catalyst tutorial on the website.

If this sounds like something you need to do then read on.

What we are going to do is implement SSH tunneling. SSH is used to ‘tunnel’ through the firewall. We then redirect port 80 on the web server through the SSH tunnel to port 1066 on the local machine.

You will need to have SSH login details to access your webserver.

On Windows

You will need to have Putty installed on your PC.

Start Putty.

Enter your SSH login URL as the host name, and if no alternative port has been specified for SSH, 22 as the host port.

In the left hand column go to Connection -> SSH -> Tunnels.

In the source port type 1066.

In the destination you will typically type ‘localhost:80′. However this may change if the web application you are accessing runs on a different port (e.g. Tomcat applications usually run on port 8080, and your own application may be something different), so you may have to type localhost:8080 to access Tomcat without going through the main webserver. In addition the localhost part of this may change if the webpages you are trying to access are on a different machine to the one you are trying to SSH into (e.g. you may have to type node2:80 if the machine you are logging into is connected to node2 as the machine you are running the web application on).

Click Add.

In the left hand column click ‘Session’ at the top.

Click ‘Save’ to save these settings.

Click Open.

You will be prompted for your username and password. (This opens a shell on your target machine so you can run linux command lines here).

To view the web application visit the following URL in your browser. http://localhost:1066/

On Linux

This can be done by opening a terminal window and typing in:

ssh -L 1066:localhost:80 username@websiteURL

In your webbrowser then going to http://localhost:1066 will give you the tracking system front end.

To do this I needed to have the following code. The main tricks here are to create a second query as well as the main page query using the WP_Query method, and that the parameter for such a query needs an s=… to let it know the phrase being supplied is a search term.

The get_post_meta() method allows extraction from the main page extra parameter list.

<?php

$query_string = get_post_meta($post->ID, ‘organism_class’, true) ;
$search = new WP_Query( "s=$query_string&showposts=5" ) ;
$search_posts = $search->query( "s=$query_string&showposts=5" ) ;

while ($search->have_posts()) : $search->the_post();
?>

<h4><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></h4>
<?php the_content(); ?>

<?php endwhile; ?>

Since then the recovery window pops up every time the program gets started and fails because the item doesn’t exist.

The solution is to delete the OpenOffice.org recovery file. Its located at the following subdirectory of the user data directory.

AppData\Roaming\OpenOffice.org\3\user\registry\data\org\openoffice\Office\Roaming.xcu

You can include this in WordPress using the following in the header.php file in your template.

<meta name="description" content="<?php the_title() ; ?> " />

Finally when having to rename a load of these files I’d had enough. Googling the answer pointed me to some Microsoft forums which gave technologically advanced answers like registry editing and someone even suggesting recreating your user profile. This was from Microsoft!

Somewhere in one of the threads someone pointed out that this only happened when accessing the Documents through a ‘Library’. Libraries in Windows 7 are a useful feature to my personal account as they are a useful way of accessing a spread apart music or video collection via a single access point, especially given an external disc. But it seems some sort of caching issue creeps up with accessing folders in the Library.

The problem I had was that accessing something as u:\users\rishistar\My Documents\test\ still resolved to a Libraries path so I right clicked on each library and deleted each one. I don’t use them on my work account so this was fine for me. YMMV.

As a coda I did have to re-create my favourite shortcuts in the top left of the Explorer pane but that was no big deal.

Again a SELECT statement with a WHERE clause is needed. The  method below will give the statement for the start and end times of the statement. Unlike the earlier example this has a DateFormat to supply the String required to generate the SQL statement.

GregorianCalendar calStart = new GregorianCalendar() ;
 calStart.set( Calendar.HOUR_OF_DAY, 18 ) ;
 calStart.set( Calendar.MINUTE, 1 ) ;
 String sql = "SELECT * FROM " + dbh.userTable.tableName +
          " WHERE status=1 AND "
          + SQLStrings.getWhereBetweenDates( "signup_time", calStart ) ;

.....

public static String getWhereBetweenDates( String columnName, GregorianCalendar calStart)
{
    GregorianCalendar now = new GregorianCalendar() ;
    StringBuffer sb = new StringBuffer( columnName + " BETWEEN " ) ;
    SimpleDateFormat df = new SimpleDateFormat( "yyyy-MM-dd HH:mm:ss" ) ;
    String beforeDateString = df.format( calStart.getTime() ) ;
    String afterDateString = df.format( now.getTime() ) ;
    sb.append( beforeDateString + " AND " + afterDateString ) ;
    return sb.toString() ;
}

Note that the DateFormat String here was determined by what was present in the MySQL database for that particular column. YMMV – so if there are problems maybe check your database table to see what particular format that column takes.

This can be achived using the following.

String sql =
“SELECT * FROM orders WHERE day(time_outgoing)=” + day ;
Statement st = con.createStatement() ;
ResultSet rs = st.executeQuery(sql) ;

Something similar can be done for months and years, and Java’s Calender class provides fields for moth access. However note that the java.util.Calender fields for months are indexed from 0, so the actual integer value of Calender.MAY is 4 and not 5.

int month = Calender.MAY ; //want entries for may

//increase the month by 1 to access values

String sql =
“SELECT * FROM orders WHERE month(time_outgoing)=” + (month+1) ;
Statement st = con.createStatement() ;
ResultSet rs = st.executeQuery(sql) ;

OR

SELECT *
FROM optout75308
WHERE logtime
BETWEEN “2010-05-21″
AND “2010-05-22″
AND (
contact_method = ‘ODWBPRESS1′
OR contact_method = ‘SERV2OWDBy’
)
