    <ol> <li>Your first statement....</li> </ol> <blockquote> <p>"While creating an example using Java and the com.alvazan.orm.api library, the use of "System.out.println" is prohibited."</p> </blockquote> <p>In general, no one uses in System.out.println. Hibernate does not, JBoss does not, tomcat does not. They all use a logging framework so you can configure each and every log in production and each company using tomcat or jboss or hibernate can configure it differently. If these programs use System.out.println, customers would have no control and your server would ALWAYS run slow as you NEVER want "all" logging and there is no way to turn System.out.println's off!!!!! they are always on. log.info can be turned off and on.</p> <p>The most complete answer on configuring logback can be found in their documentation</p> <p><a href="http://logback.qos.ch/manual/configuration.html" rel="nofollow">http://logback.qos.ch/manual/configuration.html</a></p> <blockquote> <p>Just clarifying that all information is typed into the logback.xml file?</p> </blockquote> <p>I am not sure what you mean by this question. logback.xml is the configuration for a logging library called logback which you can find at the link above.</p> <pre><code>Is there a diffrent file to use(other than logback.xml)? </code></pre> <p>logback has other options like a groovy file to configure it, but playOrm is using only logback.xml though any client can decide what configuration file they use since playOrm discards the logback.xml file that is checked in when delivering to other projects.</p> <pre><code>Or is the end-user to use, for instance, "com.alvazan.test.FactorySingleton createFactory"; and "com.impetus.annovention.ClasspathDiscoverer processFile"? </code></pre> <p>I am very confused by this question. The end user should not be using FactorySingleton(neither directly nor indirectly AND that class is not even in the jar because it's in the test package). The end-user will be using ClasspathDiscoverer only indirectly...in fact, end-user won't even know about these classes.</p> <pre><code>Finalizing this question, is the file path for the preceeding necessary? </code></pre> <p>Are you trying to ask is the file path in logback.xml necessary? If you want to know more about how logback works, you need to read alot of the documentation. Basically, you can do stuff like com.alvazan level=WARN to turn any classes in com.alvazan.<em>*</em>* to warn level(This is recursive and applies to children, grandchildren, etc. etc.). The ROOT logger is always defined as well in logback.xml and is the level for ALL classes in a all packages unless overridden.</p> <p>yes, the root logger in playorm is set to warn.</p> <p>At the bottom of the picture you show(your picture is cut off so not in that picture), there is a "source" tab and you may want to click that to view the xml better and it would match up with logback's documentation better as well. Here is a link to the file I bet you are looking at..</p> <p><a href="https://github.com/deanhiller/playorm/blob/486079cfefbd2b4b79e99652b24c146572663dda/input/javasrc/logback.xml" rel="nofollow">https://github.com/deanhiller/playorm/blob/486079cfefbd2b4b79e99652b24c146572663dda/input/javasrc/logback.xml</a></p> <p>root logger is clearly set to info and could be set to warn if you want. </p> <p>So, what do you want. Do you want those two log statements to go away and be turned off? Do you want ALL log statements to be turned off except WARN?</p> <p>If you want all to be turned off in ALL software libraries, just change the root logger to "WARN". If you want to turn just FactorySingleton off you can add this line</p> <pre><code>&lt;logger name="com.alvazan.test.FactorySingleton" level=""WARN"/&gt; </code></pre> <p>If you want all of com.alvazan logging turned off instead of just everything in com.alvazan.orm as you also want com.alvazan.test off as well, BUT you want all other libraries to still be on(BUT always want WARN on which you generally should want), then you could change this</p> <pre><code>&lt;logger name="com.alvazan.orm" level=""WARN"/&gt; </code></pre> <p>to the following instead</p> <pre><code>&lt;logger name="com.alvazan" level=""WARN"/&gt; </code></pre> <p>Your best bet to understand logback though is to read logback documentation.</p>

    1. COI have a requirement to access logback.xml from external folder for project mainly this xml file will be common for two projects which needs to access from outside. Should logback.xml file in project class path? can we load in class path from outside folder? Please suggest.

    2. COyes, that is just a java thing not a logabck thing....just specify that external folder ont he classpath first so that logback.xml gets loaded before any other logback.xml on the classpath(though hopefully that is the only logback.xml you have on the classpath). you can read up on classpath and classloading on the web about this.

    3. CODean. I think I need to spacify full path of logback.xml in class path right?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
