Description

The documented way to bind BTM in Jetty is as follows:

<New class="org.mortbay.jetty.plus.naming.Transaction">
<Arg><Call name="getTransactionManager" class="bitronix.tm.TransactionManagerServices" /></Arg>
</New>

but this throws a NPE on recent versions of Jetty (6.1.5+ are affected):

java.lang.NullPointerException
at javax.naming.Reference.toString(Unknown Source)
at java.lang.String.valueOf(Unknown Source)
at java.lang.StringBuffer.append(Unknown Source)
at org.mortbay.naming.NamingContext.addBinding(NamingContext.java:1367)

Ludovic Orban added a comment -

Jetty acquires a javax.naming.Reference object of the BitronixTransactionManager, logs it then binds it to JNDI. The log is calling Reference.toString() which throws that NPE.

A new StringRefAddr("TransactionManager", "BitronixTransactionManager") has been added to the generated javax.naming.Reference object created by BitronixTransactionManager.getReference().

This prevents the Reference from throwing a NPE when toString() is called on it.
