This incredible walled town has been built on the top a massive rocky outcrop within the Haraz Mountains of western central Yemen in a region known as the San‘a’ Governorate. Its history is so ancient that not even the inhabitants can be sure when the first settlers arrived but it is officially said to date back to at least the 12th century. The houses themselves are fortified and feature substantial storage facilities such as granaries and cisterns in case of siege. Secluded and remote, its culture and traditions have survived into the 21st century. Al Hajarah literally means “Of (the) Rock”. The lands surrounding the town are relatively fertile and the area receives sufficient rain to grow wheat, barley and grasses which support typical Arabian livestock such as goats, camels and horses. Its inhabitants are said on essay to be friendly with a passion for dancing and traditional music.

2. XUANKONG SI - CHINA

There are five Most-Sacred mountains in China and Mt. Heng (Heng shan) located in Shanxi province is one of them. Close to its base and overlooking the wooded Golden Dragon River (Jinlong he), is Xuankong Si, sometimes written as Xuan Kong Si, which literally translates as the Monastery in Mid Air. It is more often called the Hanging Monastery. Built in 491AD it still clings to the side of the cliff using engineering techniques that are still of significant interest to modern architects. Horizontal shafts were first cut into the side of the mountain to serve as the anchor points. Strong lengths of hard wood cut from single trees were then driven into the holes. The depth of the holes and the hardness of the rock provided a strong base. There are sufficient supports to ensure that if the crossbeams ever need to be replaced then one can be removed at a time without impacting on the structural integrity of the monastery. It may be the first recorded instance of deliberate over engineering.

3. CAPPADOCIA - TURKEY

This bizarre but beautiful place located in the ancient region of Anatolia in modern day Turkey may be one of the oldest examples of continuous human habitation in the world. It is an incredible example of how people have shaped and modified the already unusual geology and yet retained the natural mystery of its rocky spires and eye-twisting landscapes. It is a UNESCO World Heritage Site and there are records from the 6th century BC that describe it, even then, as one of the oldest regions of the Persian Empire. The best examples of this form of human habitation can be found in the town of Göreme where sandstone deposits have been eroded into hundreds of spectacular toadstool shapes. In turn, these have been carved into by the inhabitants and turned into homes, monasteries, churches and even a police station. It currently has a population of 2,500 people and is one of the most famous historic tourist destinations in Turkey.

4. ROUSSANOU MONASTERY

In the heart of central Greece and on the edge of the Plain of Thessaly are the Metéora, which literally means the rocks suspended in air. It’s from this word that we get the modern word meteors – rocks from outer space. In reality they are pillars of harder than average sandstone that have survived the erosion of the softer material that once surrounded them. Six religious retreats have been built on top of these pillars and one of the most famous is the Roussanou Monastery. It was rebuilt by two brothers, Maximos and Ioasaph (Joseph)*, in 1545 and dedicated to St. Barbara whose sacred day is the 4th of December. Over the centuries its fortunes grew and faded. From 1730 to 1937 it was largely uninhabited although many of its relics remained within its walls. Shortly after the Nazi occupation of Greece in 1941 it was stripped of its treasures by the occupying soldiers. Most of these have never been recovered. The monastery consists of three levels which include the church, cells, guest quarters, reception halls and a display hall. It is truly a remarkable place that has to be seen to be appreciated. Sadly, the new road at the base does detract from the mystery.

5. SETENIL DE LAS BODEGAS

It’s amazing how people have the ability to take even the most unusual of environments and still find a way to build their homes. Setenil De Las Bodegas is one such place. Located in the Andalucía province of Spain it has a history that may date back many thousands of years. What makes it special is the way that its inhabitants have carved away the walls of the gorge and then built their houses into the recesses. These are not the ruins of Mesoamerican Native Indians or the abandoned caves of lost biblical civilizations. These are homes that have been built and rebuilt over the centuries and are still occupied to this day. Outcrops of ancient rock loom over the main street that has been built beneath. In one place there are houses that have a million tons of rock above them and on top of that rock there are even more houses.

The main class APojo should have the annotation Cli:
@Cli(name="something")
public class APojo {
…

The left over arguments will not be passed in unless the class has a setter method (naturally enough):
public void setArguments(List<String> arguments) {
this.arguments = arguments;
}

For Collection or array, it's [ ele1, ele2, …], the expression of element follows same rules
For Map, it's { key1 = value1, key2 = value2, …}, the expression of key and value follows same rules
For others, it's what toString() returns.

Also, can I group options together (separated by blank lines), so that —username and —password can be together, for instance?

could you give me some advice where is problem or what i did wrong??

I'm controlling jmxterm from a Python script, and I'd like an automated way to funnel the data returned in Python objects. What is the data format that is used to return the values?

Thanks,

Mark

echo "get -s -b java.lang:type=Runtime Name" | java -jar …

I'd like to execute several commands when using Jmxterm in non-interactive-mode. First I'd like to connect (via "open") and then I'd like to get the value of a mbean. I tried

 echo "open 7358; get java.lang:type=Runtime Name" | java -jar jmxterm-1.0-alpha-4-uber.jar -n 

Many thanks in advance!

"run browse myprop LIKE 'foobar_%'" calls operation browse("myprop", "LIKE", "'foobar_%'") of selected bean, is it the right operation you attempt to call?

So try "bean module\-name=cluster". If you still see an error, please feel free to report a bug in http://wiki.cyclopsgroup.org/jmxterm:support. Thanks.

foo-baa.xyz.cluster:module-name=cluster

Looking at PATTERN_PROPERTIES in the source, it uses the word regex "\w", I don't think this allows for hyphens although I haven't coded in java in a long time.

$>domain foo.baa.cluster
#domain is set to foo.baa.cluster
$>beans
#domain = foo.baa.cluster:
foo.baa.cluster:module-name=cluster
$>

No matter what arguments I pass to the "bean" command I always get a Bean name isn't valid error.

I have an ActiveMQ enviroment. I'd like to use jmxterm for quering my 'FOO.BAR' queue.

I need to retrieve all messages matching a condition on a custom message property (e.g. in my messages the myprop property can assume the values foobar_1,….,foobar_N).

I tried to call:
run browse myprop LIKE 'foobar_%'

but it doesn't work, instead it works perfectly e.g. in jconsole :(

Someone can help me?

Best regards,

Michael

Is there a way to fix this issue or prevent this NPE from showing. Also, the CLI seems fairly verbose, is it possible to turn off all the messages that report what its doing.

The next release will allow you to specify user name with boot command argument. Sorry for the inconvenience.

So far I didn't intend to exposed public API for people to extend. I thought the best way to call JMX programmatically is to call javax.management.remote directly. However most classes are public(http://cyclopsgroup.org/projects/jmxterm/apidocs/index.html) and you are always free to call them directly. If you do, you will take the risk of API signature change in future releases.

Can you talk a little more about the use case for public API usage? So that we can figure out the best way to handle it together.

Also, is jmxterm available in any Maven Repositories so that I can add a dependency to my pom?
