[java.lang.ClassCastException, when creating EJBQL connection data Adaptor in jasper studio version 6.0.1]

I created  EJBQL connection data Adaptor.

and added below jars to  jasper studio classpath.

1. hibernate-entitymanager.jar

2. jar file containing entity classes and persistence.xml

3. other dependent jars.

 

Below is the part of persistence.xml  file content

 

    <persistence-unit name="test-ejb-entityPU" transaction-type="JTA">

        <provider>org.hibernate.ejb.HibernatePersistence</provider>

        <jta-data-source>jdbc/testDS</jta-data-source>

        <properties>

            <property name="hibernate.transaction.manager_lookup_class"

                value="org.hibernate.transaction.WeblogicTransactionManagerLookup" />

            <property name="hibernate.hbm2ddl.auto" value="none" />

            <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" />

        </properties>

    </persistence-unit>

 

When I click on test button in EJBQL connection data Adaptor window in Jasper Studio

I get below Exception 

java.lang.ClassCastException: org.hibernate.ejb.HibernatePersistence cannot be cast to javax.persistence.spi.PersistenceProvider

 

Let me know  if any one has any idea on this exception.

 

[Frames Alignment issue in Detail Band]

I solved the issue by my self. 
I used sub-report in place of Frame 2

[Frames Alignment issue in Detail Band]

I am Using Jasper Reports Version 3.7.6. In my report in Detail Band I am having 6 Frames as shown in attached Image file. Except "Frame 2" the remaining Frames are of Static size. Only for Frame 2 the content is dynamic and it stretches its height as per content. One Problem I am facing is When "Frame 2" height is more then Frame 1 and Frame 3 it adds extra space space(which shown in attached image) below Frame 2 in generated Report. I want this Extra space to be ignored by jasper engine when "Frame 2" height is more then Frame 1 and Frame 3. Any sugeestions?

[Adding jar files to Classpath Programatically.]

one way of adding jar files for Classpath in iReport is to add the jars as below:-

Tools >> Options >> Classpath  

 

I want to add jars files to Classpath programatically.

 

For EX:- I have written following  batch script in Windows to start irepot.

SETLOCAL

call  ".\bin\ireport_w.exe " 

ENDLOCAL

In this script, I want to add the jars to iReport classpath.

is there any way for this..???
