Declaring Isolation level

[Deena]

Dear All,

Can any of you let me know where the Isolation levels specified during an EJB development and deployment?

Can you let me know the exact details.. Is it in ejb-jar.xml? If you can let me the exact tag descriptors, it will be really of great help?

You specify transaction isolation levels in ejb-jar.xml. The list of transaction isolation levels are:

Mandatory
Required
RequiresNew
Never
NotSupported
Supports

You specify them at the method level under the <assembly-descriptor> section of the ejb-jar.xml.

Ex:

<assembly-descriptor>
....
....
<container-transaction>
<method>
<ejb-name>NextIdBean</ejb-name>
<method-intf>Local</method-intf>
<method-name>setId</method-name>
<method-params>
<method-param>int</method-param>
</method-params>
</method>
<trans-attribute>Required</trans-attribute>
</container-transaction>
...
...
</assembly-descriptor>
