Update
1 ) Reading on the internet I a message post # https://developer.jboss.org/thread/213711?tstart=0&_sscc=t :
use Hibernate with c3p0.
I had exactly the same problem after an attempt to upgrade from
Hibernate 4.1.3 to 4.1.8.
Downgrading back to 4.1.3 solved the problem.
c3p0 version in both cases is the same: 0.9.1.
2) The answer at Abstract Method Error states that is could be "due to version incompatibility in some of the jar file."
3) Same error: Error when saving #Lob with hibernate java mysql
Update2
I was able to bypass the error ( fix? ) by changing the Resource driverClass in server.xml.
I had the following:
<Resource auth="Container"
driverClass="oracle.jdbc.OracleDriver"
maxPoolSize="20"
minPoolSize="2"
acquireIncrement="1"
name="jdbc/g"
user="egrants"
password="egrants"
factory="org.apache.naming.factory.BeanFactory"
type="com.mchange.v2.c3p0.ComboPooledDataSource"
jdbcUrl="jdbc:oracle:thin:#//localhost:1521/XE"
automaticTestTable="t_test_c3p0" idleConnectionTestPeriod="300"/>
Changing to the following stopped the error:
<Resource
name="jdbc/g"
auth="Container"
type="javax.sql.DataSource"
driverClassName="oracle.jdbc.OracleDriver"
url="jdbc:oracle:thin:#127.0.0.1:1521:xe"
factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
username="root"
password="root"
maxActive="20"
validationQuery="SELECT 1 FROM DUAL;"
testOnBorrow="true"
maxIdle="10"
maxWait="-1"/>
I have a feeling though there must be a downsite to this switch since the previous developer had written the previous definition.
How would I go about using the original c3p0 definition but avoiding the error?
Next things to try:
Change a jar file on the tomcat server?
Modifying my pom.xml .

Summary
Two workarounds/fixes I found:
Updating the JAR files within the tomcat/lib folder
Switching to a different driver in my server.xml resource definition.
Updating Jar files
Adding a definition in my pom.xml didn't work strangely as they didn't seem to be generated in the war. I resorted to updating the jars in the tomcat/lib folder.
cd apache-tomcat-6_0_36-ep-01/lib
ls
mv c3p0-0.9.2-pre4.jar c3p0-0.9.2-pre4.jar.OLD
wget http://central.maven.org/maven2/com/mchange/c3p0/0.9.5/c3p0-0.9.5.jar
mv mchange-commons-java-0.2.2.jar mchange-commons-java-0.2.2.jar.OLD
wget http://central.maven.org/maven2/com/mchange/mchange-commons-java/0.2.9/mchange-commons-java-0.2.9.jar

I tried removing the allowMultiQueries option now but the connection is still giving me an error.

You have to add the Driver, not the Sources :-)
Check the file name for your driver. You'll want
mysql-connector-java-5.1.37-bin.jar
or with highlighting: You have mysql-connector-java-5.1.37-source.jar, you need mysql-connector-java-5.1.37-bin.jar
Good luck :-)
Edit / Your Question changed
message from server: "Too many connections"
You need to reduce number of max / initial connections to something moderate. I recommend
maxActive="25"
maxIdle="10"
maxWait="10000"
minEvictableIdleTimeMillis="55000"
minIdle="5"
for starters.

javax.naming.NamingException: Cannot create resource instance - Tried many different ways

I have tried many different ways to fix this issue but it is throwing error as below. We are using CXF Framework to write web services and read data source from context.xml file. It works fine for data source which connects to database or other system source as well but doesn't work for data source con/TestAPI that i am trying to add now. Not sure what is the issue here.
Please help.

Exception while deploying my JPA-application to Websphere 7

I have problems deploying a web application to the most recent version of IBM Websphere 7.
The exception is caused during the JPA initialization.
The application is using servlet 2.5, eclipselink 2.1.3, java 6 update 25.
persistence.xml is using version 1.0
I am unsure, if this exception is caused by a bug/configuration error in Websphere or by my application. Maybe it's also related to eclipselink.
UPDATE
Our application does not use JNDI for providing datasources to EclipseLink. Our application passes the DataSource directly to EclipseLink (using EclipseLink specific EntityManager properties)
The persistence.xml I am using is (leaving out all entity definitions and tuning properties):
<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"

The empty non-jta-data-source is causing WebSphere Application Server to perform a lookup(""), which returns the root context, which it then attempts to cast to DataSource.
Container-managed JPA is designed for the container to acquire the data source and pass it to the EM itself. I would recommend that you either specify your data source in persistence.xml, or just disable container-managed JPA altogether to avoid the error during application start:
http://www-01.ibm.com/support/docview.wss?uid=swg1PM26361

Websphere seems to be validating your data-source value in your persistence.xml, and it seems to be invalid. You need to specify a valid value, even if you are overriding it later.
Please include your persistence.xml. You could also try not setting a data-source, or using resource_local if it does not allow no data-source.

In your EAR config you have set a JNDI context where there should be a JNDI DataSource

jndi database connection with jpa and eclipselink

I try to setup a database connection in java with JNDI in combination with eclipseLink/JPA on Tomcat 5.5. I already configured the JNDI resource in web.xml and context.xml.
The db connection works with JNDI without using JPA and eclipseLink.
After configuring the persistence.xml for eclipseLink, I got the following exception.
I don't know how to configure the persistence.xml correctly to use JNDI datasource for the db connection.
The exception

Just add the class JPAEclipseLinkSessionCustomizer to your project and configure the persistence.xml as shown below:
<persistence-unit name="yourUnit" transaction-type="RESOURCE_LOCAL">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<non-jta-data-source>java:comp/env/jdbc/yourDs</non-jta-data-source>
<properties>
<property name="eclipselink.session.customizer" value="com.company.yourproject.yourpackage.JPAEclipseLinkSessionCustomizer"/>
</properties>
</persistence-unit>
You need this workaround only for Apache Tomcat.

Set the datasource URL to "jdbc/myDs"
<non-jta-data-source>jdbc/myDs</non-jta-data-source>

I hope you could solve the problem with the comments given ...
I fix it by adding a property "javax.persistence.nonJtaDataSource" with the same value as the element non-jta-data-source

I think you need to code a workaround for the javax.naming.NamingException: This context must be accessed throught a java: URL exception as detailed at http://wiki.eclipse.org/EclipseLink/Examples/JPA/Tomcat_Web_Tutorial#Session_Customizer
