Managing a Session Manually

[Georg Schmidl]

When implementing the example code for "Managing a Session Manually" described at

https://developer.atlassian.com/display/CONFDEV/Hibernate+Sessions+and+Transaction+Management+Guidelines

I get the following exception:

caused by: java.lang.ClassNotFoundException: org.springframework.orm.hibernate.HibernateCallback
    at org.apache.felix.framework.ModuleImpl.findClassOrResourceByDelegation(ModuleImpl.java:772)

Ok I found out that the org.springframework.orm.hibernate package is not available, so this is impossible.

There's an example implementation at the bottom of this page: https://developer.atlassian.com/display/CONFDEV/RPC+Module

Ah, that really sucks.

Actually... there is a section on doco that you linked that specifically discusses what to do in plugins. You should be able to use com.atlassian.sal.api.transaction.TransactionCallback; and com.atlassian.sal.api.transaction.TransactionTemplate; to manage a hibernate session without interacting with any of the hibernate classes directly.

[Georg Schmidl]

That worked. Thanks!

[Joe Clark]

Awesome! Sorry I didn't point this out straight away and sent you on a goose chase with your plugin's bundle intructions. :-)

So, I found these instructions a bit incomplete.  in my atlassian-plugin.xml file I needed to add the following before Spring could import the object:

<component-import key="transactionTemplate" name="Hibernate Transaction Template" interface="com.atlassian.sal.api.transaction.TransactionTemplate" />

After that, I could use the normal mechanism to pull the object in via the class constructor.

If your atlassian-plugin.xml has an <Import-Package> element, make sure that you are importing the org.springframework.orm.hibernate namespace.

I've added

<Import-Package>org.springframework.orm.hibernate,*;resolution:=optional</Import-Package>

to my plugin and now I'm getting this at installation:

Caused by: org.osgi.framework.BundleException: [...] Unable to resolve 89.0: missing requirement [89.0] package; (package=org.springframework.orm.hibernate)
