we have move the code on new server, as previously we are using the tomcat6 but on new system installed the tomcat7. so we are getting the below error, i did the googling and make the changes but still getting same error. the error as below.

The error clearly says the connection was abandoned. This means one of two things. Either somewhere in your code, you're not closing the connection properly, or you have a long running query that exceeds the timeout (a minute in your case) so Tomcat wrongly believes it's been abandoned. Make your DB log slow queries, or profile your app to figure out if the latter is the case.
This is working with Tomcat 6 because that version doesn't include timeout functionality. That's why the query is running properly without a timeout.

I am running Tomcat7 on a provisioning server (Ubuntu OS) to provision devices. Issue is http stops working after couple of more days and when i restart tomcat everything get back on normal.
I've gathered below logs.

Any idea / help
Bill, you will have to analyse thread dumps and will have to go through your application code once. It seems objects are not getting GC.
But before that, to prove this analogy, you can try to double your Memory.
In your catalina.sh/catalina.bat (depending on OS) please try to modify your -Xmx, -Xms and -XX:MaxPermSize and observe if it has any impact on your server uptime.

Have been trying to fix it from hours. Searched google and similar issues with no success. I am exhausted. How to fix it? I just want to see DataSource working.
Details
JDK 6.1
netbeans 7.2
tomcat 7.0.27
This appears to be the best guide that I can find:
http://tomcat.apache.org/tomcat-7.0-doc/jndi-datasource-examples-howto.html
A quick test would be to put it here:
$CATALINA_BASE/conf/context.xml
I want to implement connection pooling on my Tomcat server. Here is my context.xml file (placed under WebContent/META-INF/context.xml:
<Context path="/evappserver" reloadable="true">
<Resource
name="jdbc/evapp"
auth="Container"
type="javax.sql.DataSource"
factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
initialSize="34"
maxActive="377"
maxIdle="233"
minIdle="89"
timeBetweenEvictionRunsMillis="34000"
minEvictableIdleTimeMillis="55000"
validationQuery="SELECT 1"
validationInterval="34"
testOnBorrow="true"
removeAbandoned="true"
removeAbandonedTimeout="55"
username="root"
password=""
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/evapp?allowMultiQueries=true"
/>
</Context>
I have a maven project so the mysql jdbc driver is imported via the pom.xml file, like this:
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.6</version>
</dependency>
Here is my java code which throws the exception:
Context initContext = new InitialContext();
Context envContext = (Context) initContext.lookup("java:/comp/env");
dataSource = (DataSource) envContext.lookup("jdbc/evapp"); //here is the exception
Here is the exception:

Is there something wrong with this configuration?
I think you should include the driver for MySQL in your tomcat /lib folder instead of deploying it along with your web application. This way the server will find the proper classes to instantiate your connection pool and everything should go fine.
check if the classpath of your project contains the file mysql-connector-java-5.1.6.jar. Did maven run without problems?
I had this same problem. For a reason unknown to me, putting the mysql-connector-java*.jar in WEB-INF/lib no longer works in Ubuntu LTS 14.04
I solved it by copying this file (and this file alone) to /usr/share/tomcat7/lib and restarted tomcat7 as a service service tomcat7 restart and everything sprang to life.
Best of luck
I recently upgraded my NetBeans IDE from v7.3 to v8 and all of a sudden my application throws an exception at server startup while connecting to DB. The only difference between these two versions of IDE are that the later one is using Tomcat 8.

<!-- PostgreSQL Datasource -->
<Resource auth="Container" driverClassName="org.postgresql.Driver" factory="org.apache.tomcat.dbcp.dbcp.BasicDataSourceFactory" maxActive="50" maxIdle="10" maxWait="-1" name="jdbc/mydb" type="javax.sql.DataSource" url="jdbc:postgresql://myorg.corp.net:5432/mydb" username="abc" password="def" />
Please guide.
The name of the default factory changed between Tomcat 7 and Tomcat 8. A couple of attribute names also changed. This is all as a result of switching from DBCP 1.x to DBCP 2.x in Tomcat 8. You want the following in your META-INF/context.xml file:
<!-- PostgreSQL Datasource -->
<Resource auth="Container"
driverClassName="org.postgresql.Driver"
factory="org.apache.tomcat.dbcp.dbcp2.BasicDataSourceFactory"
maxTotal="50"
maxIdle="10"
maxWaitMillis="-1"
name="jdbc/mydb"
type="javax.sql.DataSource"
url="jdbc:postgresql://myorg.corp.net:5432/mydb"
username="abc"
password="def" />
Since this factory is used by default for resources of type javax.sql.DataSource you can just drop that attribute all together. The other changes were:
maxActive -> maxTotal
maxWait -> maxWaitMillis
You need tomcat-dbcp-8.0.0-RC1.jar in your tomcat8 lib folder. The package structure for org.apache.tomcat.dbcp.dbcp2.BasicDataSourceFactory in commons-dbcp.jar is different from other tomcat versions.
Asked in gis.stackexchange: https://gis.stackexchange.com/questions/23412/could-not-obtain-native-oracle-connection
Anyone knows the the cause and how to resolve the "Could not obtain native oracle connection" error?
I'm using GeoTools 2.7.4, a oracle 11g DB, ojdbc14.jar, and a simple java code on a Tomcat 6 like this:
Map map = new HashMap();
map.put( "dbtype", "oracle");
map.put( "jndiReferenceName", "java:comp/env/jdbc/GisDS");
OracleNGJNDIDataStoreFactory factory = new OracleNGJNDIDataStoreFactory();
log.info("Can process? "+ factory.canProcess(map));
store = factory.createDataStore(map);
SimpleFeatureSource featureSource = store.getFeatureSource(viewName);
log.info(featureSource.getFeatures().getBounds().toString());
And my context.xml:
<Resource name="jdbc/GisDS" auth="Container" type="javax.sql.DataSource"
driverClassName="oracle.jdbc.driver.OracleDriver"
accessToUnderlyingConnectionAllowed="true"
username="***" password="***"
url="***"
maxActive="25" maxIdle="8" maxWait="10000"
removeAbandoned="true" removeAbandonedTimeout="60" logAbandoned="true"
poolPreparedStatements="true" maxOpenPreparedStatements="100"
validationQuery="SELECT SYSDATE FROM DUAL"/>
And I always get the "Could not obtain native oracle connection" error:

I've tried to connect to a 10g DB, I've tried using the ojdbc6, and I always end with the same result.
The strange thing is, if I replace the getBounds() with size() it works.
