25	25	One important thing to remember is that you need to build and install the frameworks before your build your applications. Building your applications will NOT add the frameworks to the product if you didn't build the frameworks first. So let's build and install the **BlogCommon** framework first.

48	48	= Configuring the applications with JavaMonitor =
	51	+
	52	+Before adding the application into JavaMonitor, you have to copy the applications on the deployment server. You can use any tools that you usually use to copy files on the remote server (scp, rsync, CyberDuck, etc.). Usually you need to copy the application to the following remote directory:
	53	+
	54	+* /Library/WebObjects/Applications (on OS X)
	55	+* /opt/Local/Library/WebObjects/Applications (on other UNIX systems than OS X, like Linux, BSD or Solaris)
	56	+
	57	+Copy the **BlogRest-Application.tar.gz** archive into the correct directory from the above list and uncompressed it (//tar zxf BlogRest-Application.tar.gz//). This will create a new directory named **BlogRest.woa**.
	58	+
	59	+One last step to do for the application. Usually, the application will run with the //appserver// user and the //appserveradm// group. You need to make sure that either the group or the user can run the application. The best way to do this is to change the group of the files to be //appserveradm//. Your user on the deployment server should also be part of that group. To change the group:
	60	+
	61	+{{code}}
	62	+chgrp -R appserveradm BlogRest.woa
	63	+{{/code}}
	64	+
	65	+You also need to install the Web server resources to a different location. Why is that? Because it's better to serve static resources like images and CSS from the Web server software (Apache, IIS, etc.) than from the Web application to get better performance and caching.
	66	+
	67	+Usually, the Web server resources goes to:
	68	+
	69	+* /Library/WebServer/Documents/WebObjects (on OS X)
	70	+* /opt/Local/Library/WebServer/Documents/WebObjects (on other UNIX systems than OS X, like Linux, BSD or Solaris)
	71	+
	72	+Copy the **BlogRest-WebServerResources.tar.gz** archive into the correct directory from the above list and uncompressed it (//tar zxf BlogRest-WebServerResources.tar.gz//). Doing this command will result in a new directory called **BlogRest.woa**.
	73	+
	74	+Everything on the file system is ok, the next step is to add the application to JavaMonitor. If the development tools have been installed correctly, JavaMonitor will run on port 56789 on your deployment server. For example, if the DNS name of your deployment server is my.host.com, the URL will be [[http://my.host.com:56789]]
	75	+
	76	+After the **Add Application Named** label, enter **BlogRest** into the text field and click **Add Application**.
	77	+
	78	+You will get to a page where you need to specific the path to the launch script inside the application bundle. If the development server is on OS X, the path will be:
	79	+
	80	+{{code}}
	81	+/Library/WebServer/Documents/WebObjects/BlogRest.woa/BlogRest
	82	+{{/code}}
	83	+
	84	+Put that path in the text field next to the **MacOSX** label.
	85	+
	86	+On other UNIXs, the path is:
	87	+
	88	+{{code}}
	89	+/opt/Local/Library/WebServer/Documents/WebObjects/BlogRest.woa/BlogRest
	90	+{{/code}}
	91	+
	92	+Put that path in the text field next to the **Unix** label.
	93	+
	94	+It would also be useful to log problems to a log file. For now, we will put the log into ///tmp//. That means that the log will be lost when you reboot the server or if you have tools that clean the ///tmp// directory every day, but for now it would do the job.
	95	+
	96	+To specify the path to the log file, go to the **Output Path** section and enter ///tmp// in the text field next to **MacOSX** (if your deployment box is on OS X) or next to **Unix** (if your development is UNIX but not OS X).
	97	+
	98	+The next step is to click on the **Push All** button, which saves the application configuration. Now, we can add instances of the application. To do so, click on the **Detail View** link.
	99	+
	100	+You will see a section saying Add: 1 instance(s) on host: . Click the **Add** button. That will add one instance of the application. It's possible to run multiple instances of an application, mainly to load balance requests and also to have other working instances in case an instance is going AWOL. But for now, running one instance is enough.
	101	+
	102	+If the application launches successfully, a link on the application name will appear after 30 seconds in JavaMonitor. If a link does not appear after a minute and the status is still **STOP**, something is wrong. Check the log that was created in /tmp (the log should be /tmp/WOCommunity-1) to check for any errors.
	103	+
	104	+If the log file does not exist, 99% of the time, the problem is file permissions. Make sure that the launch script for the application (BlogRest.woa/BlogRest) is accessible for the **appserver** user. If the file permissions are ok, you can launch the script manually with the **appserver** user by doing:
	105	+
	106	+On OS X:
	107	+
	108	+{{code}}
	109	+
	110	+sudo su - appserver
	111	+cd /Library/WebServer/Documents/WebObjects/BlogRest.woa/
	112	+./BlogRest
	113	+
	114	+{{/code}}
	115	+
	116	+On other UNIXs:
	117	+
	118	+{{code}}
	119	+
	120	+sudo su - appserver
	121	+cd /opt/Local/Library/WebServer/Documents/WebObjects/BlogRest.woa/
	122	+./BlogRest
	123	+
	124	+{{/code}}
	125	+
	126	+If the application can start from the command line, it should start by the development tools too. If you see errors when launching the application by command line, fix them and try to launch it by command line again.
