When I run my application from IDEA I'm getting the following warning (see below). When running the same code from outside IDEA, this warning does not appear (even though the file isn't really there as well.
Seems like everything is working OK, but still, it's kind of annoying... how can I get rid of it?
(BTW I'm using Tomcat embedded).

From your question it isn't clear which logger is logging this warning (looks like one of the Tomcat's) and neither which version of Tomcat you are using, but you can generally fine tune the log levels in Tomcat. More information here:
http://tomcat.apache.org/tomcat-6.0-doc/logging.html
I wouldn't really advise you to disable warnings however.

I'm trying to create a Rest application with Jersey using Maven but I always end up having the same errors.
I downloaded the default zip on the Jersey website and set up my jars in the project, but every time I start the application the following error is returned:

I would request you to help in this,Thanks.
Seems like its a reported bug and fixed, try to upgrade your java version
Fixed Versions:
6u29-rev (b22)
I have a test tomcat server that our developers use to test their apps. We have about 44 small apps (40-80MB). If I run tomcat 8.0.26 with jdk1.8.0_05 or jdk1.8.0_11 all the apps load find and are available to users.
If I use jdk 1.8.0_20 or later versions the server crashes with memory errors after loading about 15 apps.
The server is a SuSE Linux Enterprise 11 SP3. 8 GB RAM , 2 VCPU's
I'm using the same JAVA_OPTS for each test.
JAVA_OPTS="-server -Xms4096m -Xmx4096m -XX:NewSize=128m -XX:MaxNewSize=256m -XX:MetaspaceSize=256m"
Just wondering what changes were made after jdk1.8.0_11 that could cause these issues?

I'm implementing Dbutils using net.sourceforge.jtds.jdbc.Driver driver in jtds package.
Problem is it gives me java.sql.SQLException: net.sourceforge.jtds.jdbc.Driver error even after including jtds jar in project. It works fine when i include this jtds jar file in lib folder of tomcat.
I checked build code, jtds jar file is present there.

Any idea?
You are using a connection pool and you are making use of the tomcat. See the link below, and notice the line that says "The fully qualified Java class name of the JDBC driver to be used. The driver has to be accessible from the same classloader as tomcat-jdbc.jar".
