I am trying to add a DB appender into my logback configuration.
Here is the part of the logback.xml file related to the issue:
<appender name="db" class="src.main.java.database.SqliteLogbackAppender">
<connectionSource class="ch.qos.logback.core.db.DriverManagerConnectionSource">
<driverClass>org.sqlite.JDBC</driverClass>
<url>jdbc:sqlite:/home/db/logger.db</url>
</connectionSource>
</appender>
The thing is, I use a custom appender, which is located in my scr.main.java...etc folder, but not in logback-classic library
When I run my application, I get the following error:
09:02:06,682 |-ERROR in ch.qos.logback.core.joran.spi.Interpreter#31:78 - ActionException in Action for tag [appender] ch.qos.logback.core.joran.spi.ActionException: ch.qos.logback.core.util.DynamicClassLoadingException: Failed to instantiate type src.main.java.database.SqliteLogbackAppender

However, when I write classpath on logback.xml configuration, I am able to access file with IntellijIdea IDE interface (by clicking ctrl+left_mouse_button), so I believe there are no typos.
Regards.
Be sure to use the fully qualified class name, including package, for your appender in the XML. Do not specify the path to the class.
"src.main.java.database.SqliteLogbackAppender" seems to include the Maven folders (src/main/java) and therefore likely isn't the actual class name.
Perhaps you meant just 'database.SqliteLogbackAppender'?

This error occurs occasionally while the whole function works well. But this exception can be thrown from time to time. I found one solution that copy mysql-connector-java-5.1.24.jar to tomcat/lib folder, while this error will gone. Without this, web server will eventually create too much connection to data base.
Anyone can help to explain why this occurs, and why should move jar from webapps to tomcat/lib?

I am trying to do some cost testing using JMeter, however my plan is to use the our current API unit test suite as the cost test plan, as many of the tests simulate user flows. That being said, I am running into some issues with JMeter. I have the jar with the unit tests in the /lib/junit folder as I should, however when I launch JMeter, the edit tab has no items (on mac, from my research this issue yields a greyed out edit button on windows), I cannot right click on any of the objects and the JUnit Samplers do not appear in the test plan. Here is the data from the logs:

I have been doing some research all day and so far no solutions have helped. So that no one wastes their time, results like this and really all of the google search results from various stack trace errors in this log have yielded no viable results. I am using Jmeter 3 but have tried it with jmeter 2.12 and jmeter 2.9. This may or may not be relevant, but Jmeter 2.12 works in the sense that this error does not occur, however none of the unit tests appear in the sampler.
The first line explains everything:
Missing jar?
Could not create kg.apc.jmeter.config.redis.RedisDataSet. java.lang.NoClassDefFoundError: org/apache/commons/pool/impl/GenericObjectPool$Config
This is due to missing Apache Pool jars in JMeter classpath.
It looks like your test is created somewhere with Redis plugin installed and you're currently trying to run it on a clean JMeter.
I would recommend the following:
Get "clean" JMeter 3.0
Install JMeter Plugin Manager
With the Plugin Manager install Redis Data Set
Import your test libraries into "lib/junit" folder
Restart JMeter
I solved it everyone however it doesn't really explain why those were the errors in the stack trace. The unit tests require credentials which as it turns out I had to place in the Jmeter /bin folder. Once I did this, the tests ran fine. Again, I am not sure why this caused the errors that it caused.
I suggest you :
install a clean 3.0 version
add your dependencies in jmeter/lib
your junit classes in lib/junit
if using junit 4, ensure You tick Search for JUnit4 annotations box in your JUnit Request Sampler
No need for your case to install Jmeter plugins nor plugin manager.
If issue persists show your new jmeter.log file

This shows ldap is not passed with the correct parameters. So if you can pass the mandatory parameters correctly then it will resolve the issue
I have (as far as I know) properly followed all of the instructions on xwiki.org, and I have also searched high and low for answers to my errors, but have unfortunately been unable to resolve them by myself.
I have downloaded XWiki in two different formats. The first is the .exe installer, and the second is the suggested .xar package, both for using on a Windows 8, 64 bit machine.
The first runs perfectly in "standalone" mode, but once the hibernate.cfg.xml file is changed to the preset MySQL Settings (which are accurate to my database), I get a very long HTTP 500 error. (This is after I added the MySQL Connection Java file, and created a MySQL database according to the instructions on xwiki.org) It seems that the primary issue is that it cannot find the com.mysql.jdbc.Driver along with the fact that I get an error later on the page saying that it cannot create a database connection pool.
The code pertaining to the error is this:
<!-- DBCP Connection Pooling configuration
-->
<property name="dbcp.defaultAutoCommit">false</property>
<property name="dbcp.maxActive">50</property>
<property name="dbcp.maxIdle">5</property>

And the error itself looks like this:

Do I have to use the .xar installation version to properly connect to a database? I tried that way also, with Xampp and Tomcat. Tomcat installed fine and I can easily access it through localhost:(port). However, when I try to access my xwiki, I get a HTTP 404 error saying that the reference cannot be found, which is odd since it shows up with the other files in the deployment list included in Tomcat, and the Tomcat example file shown there (located in the same Directory) works fine...
I'm a bit concerned that even if I could get the XWiki to work properly through Tomcat, I would still get the first error that I mentioned later when I try to connect the MySQL database.
Side Note: I have suspicions that there may be Java file conflicts between those found in XWiki and those in Tomcat from other errors that I have seen while playing around and trying to make things work... but I could be wrong as I currently have very little knowledge of Java. I've seen several servlet errors and could not find class/file errors that according to a Forum that I found, are common errors belonging to the jasper.jar and the jsp-api.jar, both are found in Tomcat.
Regardless, I am open to trying installation options that do or do not involve Tomcat. If anyone has had success with installing XWiki on Windows with a MySQL database, your help would be much appreciated!
Looks like you are missing the mysql driver. Since you converted the default distribution to use mysql, you will need to download a mysql driver jar and deploy it to your 'webapps\xwiki\WEB-INF\lib' directory.
Regarding the second issue, there is probably no connection between the database driver error, the xar and the tomcat 404. The xar is simply a collection of pages used to import or export content and functionality, but doesn't usually handle low level stuff like database conectivity. The 404 in Tomcat is probably due to the fact that you accessed a invalid url. Could need more details on that one.
First regarding potential conflict with Tomcat, I can assure you this is not possible as Tomcat is what XWiki team use in production all the time.
Now for MySQL, the error is pretty clear and if you really put the MySQL connector then you did not put it in the right place. What version of it did you put and is it in #xwiki folder#/WEB-INF/lib/?
The XAR package is not a different way of installing XWiki, it's a package containing wiki pages that can be imported in XWiki when it's running. Perhaps you mean the WAR package?
This was resolved some months ago. I was missing some vital information in the set-up, but it works fine now.
We started having a broken pipe issue this past Saturday with a job that gets run via a quartz scheduler during the early morning of each day. Below are some details on this.
The job consists of a native java class that calls Talend based jobs. Each of these Talend based jobs are getting the broken pipe error. Curious enough, when I run the same java class that gets submitted via the scheduler, no errors get thrown and the jobs run successfully. Also, this job stream runs in Tomcat.
Is there something I should do within the Talend jobs to see if a connection is available first? As you will see in the following jdbc parameters used for the tMysqlConnection component, the autoreconnect option is set to on.
jdbc parameters are as follows are "noDatetimeStringSync=true&connectTimeout=0&socketTimeout=0&autoReconnect=true"
Below is the stacktrace from this morning's job failure.
Any input is greatly appreciated. Thank you.
Exception in component tMysqlConnection_1
com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: The last packet successfully received from the server was 344,265,715 milliseconds ago. The last packet sent successfully to the server was 344,265,792 milliseconds ago. is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem.

Caused by: java.net.SocketException: Broken pipe

Finally got to the bottom of the broken pipe error I encountered.
The broken pipe error was being thrown due to my not closing down certain database connections
from within the Talend jobs. These connections at issue were connections that were defined in native
java (via the tJava component). It was incorrectly assumed by me that by referencing a previously
defined connection (for connection attributes), the connection resources would be closed and
released.
With the above in mind, I was actually creating a new connection as listed below and had to
specifically commit the connection and then close it out. The item to take note of here is the use
of the commit on the connection. The broken pipe error was still being thrown with just the close
of the connection. It was not until the commit was added did the broken pipe errors cease and that
was due to the connection being closed properly.
Hindsight being what it is... when using the Talend components (and not native java code) for
the connection definition and closing of that connection, the autoCommit feature is available to the
tMysqlCOnnection as well as the commit option being available for the close connection option being
available on the tMysqlCommit component. These two options allow for the prevention of a broken
pipe error and is why I only encountered broken pipe errors with the connections used by the tJava
components. Makes sense now.
// code snippet from the tJava component using native java to read a table.
java.sql.Connection tableConnection = null;
tableConnection = (java.sql.Connection) globalMap.get("conn_tMysqlConnection_1");
Statement selectStatement = tableConnection.createStatement();
// Execute statement to get the row count from the table.
ResultSet resultSet = selectStatement.executeQuery("select count(*) from tableA");
// Position the result set to allow for access of its information.
resultSet.next();
// Get the row count from the result set.
context.numberOfRows = resultSet.getInt(1);
resultSet.close();
selectStatement.close();
tableConnection.commit();
tableConnection.close();
And... I would be remiss if I did not mention that I found out about needing to use the commit
by an article on the following link. http://mikeschubert.com/2006/08/03/javanetsocketex/
