Getting rid of Root email

I've got a Linux VPS through RimuHosting - I'm no system admin, and the root account gets a pile of email spam. This takes up disk space so I try to regularly delete it. The best way I've found is to us Mutt - a console based email reader.

Firing up Mutt as root displays the thousands of spam mails recieved. Pressing 'D' lets you delete messages that match a pattern. So I can specify the pattern 'a' and that matches almost all of the messages. When quitting the application, it deletes the marked messages.

So, this is a good solution for reading or deleting many emails without downloading them - if you have ssh access.

To avoid having to do this, can anyone tell me how to stop receiving these emails?

Using the Crystal Reports Java API to generate PDF

I recently had to investigate how to generate a PDF from a Crystal Report created by another team. Without knowing anything about Crystal Reports, I had to google around for information and piece it all together. It turns out to be really simple once you know how.

We were using Business Objects 4.0, and probably the most important thing was to get the Java library - download 'SAP Crystal Reports for Java runtime components - Java Reporting Component (JRC)' from
http://www.businessobjects.com/campaigns/forms/downloads/crystal/eclipse/datasave.asp

There are a lot of samples on the web to look at - you might find something to help here:

A good example to start with is “JRC EXPORT REPORT”:

If you have an RPT file, the java to generate the report is relatively simple - :

No Scope registered for scope request

Recently I was working with some code which defined beans as request scope. Junit tests failed with the following exception while trying to initialize the application context:


Caused by: org.springframework.beans.factory.BeanCreationException: Could not autowire field: ...; nested exception is java.lang.IllegalStateException: No Scope registered for scope 'request'


I found the solution by searching around (unfortunately I didn't record the sources). Basically, you can register the required scopes as shown below:

[sourcecode language='java']
import org.springframework.mock.web.MockHttpServletRequest;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.RequestScope;
import org.springframework.web.context.request.ServletRequestAttributes;
import org.springframework.web.context.request.SessionScope;

public class SampleTest extends AbstractDependencyInjectionSpringContextTests {

@Override
protected void prepar…

Using Selenium WebDriver to select JSF/PrimeFaces selectOneMenu options

I'm using JBehave with Selenium WebDriver to test my PrimeFaces (JSF2) application. Selecting an option from a SelectOne option list isn't standard though because of the HTML markup generated by the JSF component.


The facelets code to place the selectOneMenu uses the ID 'state':


This generates HTML div blocks with id's prefixed with this components id:


To select an option, I use a method which manipulates the appropriate divs - this can be used as illustrated below:


To reuse this type of utility method, I put it in a base Page Object class:
