Syntax for flowcharts in Confluence

The Confluence wiki has this amazing Flowchart Macro that lets users draw diagrams really quickly.

Although the site for the macro combined with its comments section provides a great number of examples on what syntax to use to accomplish what you want in your diagream, its a bit scatterred so here are my facorites lsited in a neat order:

1. How do I write a line? I know how to write single words but I write multiple words with space in them then they each become separate nodes!
   
   • Instead of writing: thisIsNodeA -> thisIsNodeB
   • You can use quotations to write: "This is node A" -> "This is node B"
2. How do I add text next to the arrows leading from one node to the other?
   
   • "Node A" -> "Node B" [label="text associated w/ arrow", fontsize=10]
   • If you try this without the fontsize, it will still work but you will quickly realize that the default fontsize is way too big.
3. How do I break up the text for my line across multiple lines? How do I add a newline?
   
   • "Text for Node A \n will show up on two lines" > "Text for Node B will show up in one line"
   • The use of \n allows you to break up the text across multiple lines

Hudson, Tomcat and cacerts

Setting up a secure connection for any application, doesn't really require too much effort in terms of the process involved. It is supposed to be simple. Yet one often gets stuck on the simplest of steps simply because there is no tool or no simple answer other than trial & error.

What if someone asks you to import the server certificate into your application server's truststore. Simple right? Well no! There never seems to be a simple and straightforward answer to the question: "Well, where exactly is the current truststore?"

Where is the cacerts being used by a Tomcat instance that runs Hudson?
Navigating to Hudson > Manage Hudson > System Information will enlighten you to two possibilities:
1) the value for java.home (C:\Program Files\Java\jre6) under the "System Properties" table is a starting point, and
2) the value for JAVA_HOME (C:\Program Files\Java\jdk1.6.X_XX) under the "Environment Variables" table is another.

But not knowing which one exactly can be a bit frustrating because you need to stop and start your Tomcat again and again until you get it right. One could just import the server certificate into the cacerts file under both these locations but then you will still not know which was the right one.

Well if you are starting Tomcat as a Windows Service then the answer is use the file at ${java.home}\lib\security\cacerts. Otherwise if you use the start/stop scripts then the ${JAVA_HOME}\jre\lib\security\cacerts is your best bet.
