PDF Emailer is a iOS utility app that lets you email PDF and Office documents from Safari using a customizable email template.
In version 2.1, you can now set multiple recipients in your template by separating them with spaces.
PDF Emailer v2.1 is available for iPhone, iPad, and iPod Touch in the App Store.
We've all copied and pasted a Logger from one class to the other, forgetting to change the class name.
// WRONG
public class SomeNewClass
{
// OOPS! I forgot to change the class name!
private final Logger _logger = LoggerFactory.getLogger(SomeOtherClass.class);
// …
}
Here, use this smarter LoggerFactory which uses the stack trace to figure out what class you really mean. This is safe from copypasta laziness.
package org.blakecaldwell.logging;
import org.slf4j.Logger;
/**
* Smart logger that uses reflection to figure out the logged class
*/
public final class ClassLoggerFactory
{
/**
* Disallow factory instances.
*/
private ClassLoggerFactory()
{
}
/**
* Use the stack trace to determine the appropriate logger.
*
* @return a logger for the direct caller's class.
*/
public static Logger make()
{
Throwable t = new Throwable();
StackTraceElement directCaller = t.getStackTrace()[1];
return org.slf4j.LoggerFactory.getLogger(directCaller.getClassName());
}
}
Then, to use this logger:
// CORRECT
public class SomeNewClass
{
// No chance for screwing up anymore!
private final Logger _logger = ClassLoggerFactory.make();
// …
}
development, java, logging | in Development, Java For my current project, I need to share Spring beans between my front-end web servlets and the Spring Batch jobs that I'll launch from Spring Batch Admin (SBA). This sounds straightforward - configure the SBA servlet to listen on /batch/*, and you should be good to go. However, of course it's not that easy.
The first problem you run into is bad links in the menus, form posts that go nowhere, and missing CSS files. This is because SBA expects to be deployed on /, not /batch, or /myapp/batch which is where it will go if you deploy it inside another app. You can survive in this mode for the most part by correcting menu URLs after you click them, or use FireBug to change form actions before you submit them - for example, from /batch/files to /myapp/batch/files, but who wants to live like an animal?
Spring Batch Admin version 1.2.1 adds the ability to set the base servlet path for all links and forms by overriding the "resourceService" bean. I'm sure there are several ways to successfully accomplish this, but here's what worked for me.
Add the following repository:
<repository>
<id>repository.springframework.maven.release</id>
<name>Spring Framework Maven Release Repository</name>
<url>http://maven.springframework.org/release</url>
</repository>
and the dependencies:
<dependency>
<groupId>org.springframework.batch</groupId>
<artifactId>spring-batch-admin-resources</artifactId>
<version>1.2.1.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.batch</groupId>
<artifactId>spring-batch-admin-manager</artifactId>
<version>1.2.1.RELEASE</version>
</dependency>
Configure the Batch Admin Servlet - notice contextConfigLocation:
<servlet>
<servlet-name>Batch Admin Servlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring/batch-admin/batch-admin-context.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Batch Admin Servlet</servlet-name>
<url-pattern>/batch/*</url-pattern>
</servlet-mapping>
This is the context file that's only used by SBA. Keep in mind that any beans defined in your root Spring context will also be available to the jobs that are launched by SBA.

<property name="servletPath" value="/batch" />
</bean>
</beans>
The main "Home" link in the SBA action bar navigates to /myapp/batch. This doesn't work the way I've wired it up, because the SBA servlet is configured to listen to /myapp/batch/, but not /myapp/batch. I tried adding another servlet-mapping to /batch, but the servlet won't answer requests to it.
I'm sure there's a better way to do this via config only - please tell me if you wouldn't mind, but I opted for the more manual way, just so I could move on.
I wired up a servlet in my main web app to listen to /batch, and then have it redirect to /batch/.
Pay attention to the last servlet-mapping. This gives /myapp/batch over to Spring MVC for URL mapping.
<servlet>
<servlet-name>appServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring/appServlet/servlet-context.xml</param-value>
</init-param>
<async-supported>true</async-supported>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>appServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!-- LOOK HERE -->
<servlet-mapping>
<servlet-name>appServlet</servlet-name>
<url-pattern>/batch</url-pattern>
</servlet-mapping>
Here's where I redirect /batch to /batch/. Again, I'm sure there's a better way to do this (let me know!). Of course, for this specific code to work, you'll need some dependencies such as spring-webmvc. The bottom line is that I'm just manually listening on /batch and redirecting to /batch/.
@Controller
public class HomeController
{
/**
* Redirect the url /batch to /batch/ for the Spring Batch Admin to pick it up.
*
* @return redirect to /batch/
*/
@RequestMapping(value = "/batch", method = RequestMethod.GET)
public String redirectBatchToBatchSlash()
{
return "redirect:/batch/";
}
}
Ideally, I'd like to either get Spring Batch Admin to listen to /batch or /myapp/batch, but I'd settle on having a redirect configured in web.xml. Please tell me if you know of a good approach. I moved on with this good-enough solution.
development, java, spring, spring batch, spring batch admin | in Development, Java, Spring Mac OS X comes with Apache Maven preinstalled. However, you're still going to need to set some environment variables to get up and running.
Verify that maven installed in /usr/share/maven:
ls /usr/share/maven
Add the following line to your ~/.profile
# Set the M2_HOME environment variable
export M2_HOME=/usr/share/maven
# Put maven on your path
export PATH=$M2_HOME/bin:$PATH
This won't take effect until you either reboot or open a new terminal window. You can reload the file in the current terminal window with the following command:
source ~/.profile

You don't have time to read the document now, and it occurs to you that you should probably share this with your spouse while you're at it, so you touch the "Share" button and look for "Email". This is where you realize that your only option is to email a link, not the document itself. This doesn't help you. You are not amused.
For me, that moment of disappointment came when I had opened up a bunch of tabs with interesting articles from an online version of a magazine that I subscribe to. Emailing myself links wouldn't work, because these PDF documents require you to login first, and for whatever reason, you can't just navigate to an article by their URL. |
PDF Emailer will keep your PDF document until you delete it. This allows you to read it while offline, or email it out again later.
It runs on the iPad, iPhone, and iPod Touch, and is available now on the App Store.
