Jpa2/hibernate c3p0 pool configuration lead connection and thread leaks - jpa-2.0

I am trying to use c3p0 as connection pool provider in my application (jpa 2 and hibernate core 3.3.2) but c3p0 getting too much connection from database.This is same problem but answer not helped.I am getting entitymanager from entitymanager factory and storing entitymanager in a thread local variable,thus a am using a fresh entiymanager for each request.(by the way if i use hibernate default pool no problem)
<property name="hibernate.connection.provider_class"

Can you ensure that you are not defining pool at both datasource and sessionFactory level.

issue when profiling JVM Thread Pool ( under Spring intégration + Weblogic )

I have to maintain an application under Spring Integration (SI) and Weblogic 11g (with no workmanager configuration).
When I'm testing the performance on this application with JProfiler, I see a strange behavior regarding the threads : http://postimg.org/image/60w21njp3/
a thread pool with (approximatively) 160 threads
threads which are always created and destroyed
Under Spring, we use a SimpleAsyncTaskExecutor named "guillaume" and injected into a ListenerContainer like this :
<bean id="listenersExecutor" class="org.springframework.core.task.SimpleAsyncTaskExecutor">
<property name="threadNamePrefix" value="guillaume-" />
<property name="daemon" value="true" />
</bean>
With :
<bean id="myListener" class="org.springframework.jms.listener.DefaultMessageListenerContainer">
<property name="connectionFactory" ref="..." />
<property name="destination" ref="..." />
<property name="transactionManager" ref="..." />
<property name="taskExecutor" ref="listenersExecutor" />
<property name="errorHandler" ref="..." />
<property name="concurrentConsumers" value="..." />
<property name="idleConsumerLimit" value="..." />
<property name="cacheLevelName" value="..." />
</bean>
My question
I quote Javadoc on SimpleAsyncTaskExecutor :
TaskExecutor implementation that fires up a new Thread for each task, executing it asynchronously.
Who created the threadpool into JVM named "guillaume" ? not Spring ? Weblogic ?
Even if I don't have any activities with the SI, are there threads which are created and destroyed ?
Let me know if you need any additional informations.
Thanks.

Problems writing a for-each select with filters on multiple fields

I have an xml document with nodes that look like this:
<SQLIndexUsage>
<Property Name="database_name">ClearTrace</Property>
<Property Name="Object_Name">CTTraceSummary</Property>
<Property Name="Schema_name">dbo</Property>
<Property Name="Index_name">IX_CTTraceSummary_Date</Property>
<Property Name="Type_Desc">NONCLUSTERED</Property>
<Property Name="user_seeks" />
<Property Name="user_scans" />
<Property Name="user_lookups" />
<Property Name="user_updates" />
<Property Name="usage_ratio">0.00</Property>
<Property Name="RowError" />
<Property Name="RowState">Detached</Property>
<Property Name="Table" />
<Property Name="ItemArray">
<Property>ClearTrace</Property>
<Property>CTTraceSummary</Property>
<Property>dbo</Property>
<Property>IX_CTTraceSummary_Date</Property>
<Property>NONCLUSTERED</Property>
<Property />
<Property />
<Property />
<Property />
<Property>0.00</Property>
</Property>
<Property Name="HasErrors">False</Property>
</SQLIndexUsage>
How do I write a for-each select that will filter on multiple fields, I was working on something like this:
<xsl:for-each select="/objects/SQLIndexUsage/Property[#Name ='user_seeks'][1]!='' or /objects/SQLIndexUsage/Property[#Name ='user_scans']!='' or /objects/SQLIndexUsage/Property[#Name ='user_updates']!=''">
Or am I looking at this wrong?

In general, you should keep the conditions in a single predicate:
/objects/SQLIndexUsage/Property[
(#Name ='user_seeks' or #Name='user_scans' or #Name='user_updates') and .!='']
This is even shorter:
/objects/SQLIndexUsage/Property[
#Name[.='user_seeks' or .='user_scans' or .='user_updates'] and .!='']
This is complicated a bit by your position condition, but you can still do this (with union):
/objects/SQLIndexUsage/Property[#Name='user_seeks' and .!=''][1] |
/objects/SQLIndexUsage/Property[
(#Name='user_scans' or #Name='user_updates') and .!='']
Note: I've left /objects on the expression, even though your sample XML doesn't show it. I'm guessing you're actually working with a larger document.

Apache CXF + resource handler with embedded jetty in osgi with spring dm

I'm trying to run an apache cxf endpoint in an equinox osgi environment with jetty 7. I need the endpoint to be on address http://x.x.x.x:8080/ws/endpoint1 and have static resources on the root path http://x.x.x.x:8080/*.
I have a dedicated bundle for this purpose containing the cxf libraries. Spring dynamic modules are part of my target platform.
After some research I tried to start the jetty webserver in my spring application context.
<bean id="Server" class="org.eclipse.jetty.server.Server"
init-method="start" destroy-method="stop">
<property name="connectors">

My WebService Endpoint is declared with:
<import resource="classpath:META-INF/cxf/cxf.xml" />
<import resource="classpath:META-INF/cxf/cxf-servlet.xml" />
<bean id="someService" class="abc.xyz.SomeClass" />
<jaxws:endpoint id="endpointId" implementor="#someBean"
address="/endpoint1">
</jaxws:endpoint>
Unfortunatly this is not working. I can reach the static resources, but not the webservice.
The log says, the WebService is published under address /endpoint1. No warnings, no exceptions.
When I change the address of the webservice to its full url
<bean id="someService" class="abc.xyz.SomeClass" />
<jaxws:endpoint id="endpointId" implementor="#someBean"
address="http://x.x.x.x:8080/ws/endpoint1">
</jaxws:endpoint>
the webservice works fine, but the static ressources are not available any more.
Is it possible with a configuration like this to publish an endpoint to a running jetty with relative address? Or am I totally wrong? Most examples I found on the web use a web.xml, but I'm not working with an application server like tomcat and need the application to be a standalone eclipse app.
Spend the whole last two nights on this, any help is highly appreciated.
Kind regards,
Onno

There are sooo many samples here. U shud be able to find what u r looking for

Spring, Apache CXF and Embedded Jetty

I'm trying create a web service capable server using Apache CXF, Spring and an embedded Jetty server. When I run my project the server seems to initialize correctly, however when I navigate to http://localhost:8080/SomeService expecting to see the service WSDL, instead I get the following exception:

I should mention that I'm using the Maven one-jar plugin, although I doubt that makes any difference to this problem.
