When JXPathContext.newContext(object) holds a collection of Hibernate proxy
entities, and search performed, LazyInitializationException illegal access to
loading collection
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Key: JXPATH-110
URL: https://issues.apache.org/jira/browse/JXPATH-110
Project: Commons JXPath
Issue Type: Bug
Affects Versions: 1.2 Final
Environment: Windows XP Professional, Java 5, Tomcat 5.5.20,
hibernate-annotations 3.3.0.ga, hibernate core 3.2.2.ga, springframework 2.0.7
Reporter: eliot clingman
In the O/R model The entity WirelessDevice has all its properties with fetch =
FetchType.LAZY
First, using annotation style Hibernate, I find all wirelessDevices (proxies)
with a named query, with some but not all of the collection properties fetched.
What this means is that a property xyz must be accessed from the
wirelessDevice proxy as follows getXyz(), NOT by invoking xyz directly.
Because accessing the latter way will result in the exception
"LazyInitializationException: illegal access to loading collection." However,
when getXyz() is invoked, the proxy will return the correct value (because it
is attached to a live Hibernate session).
FYI, here is the named Hibernate query: "select d from WirelessDevice d left
join fetch d.marketData marketData left join fetch d.wirelessTechnologyTypes
left join fetch d.anatomy anatomy left join fetch anatomy.geometry".
Any way when I do the following in JxPath , a LazyInitializationException
occurs presumable because properties are not being accessed via getters, but
rather directly:
JXPathContext context = JXPathContext.newContext(blah blah);
Iterator<T> i =
context.iterate("/wirelessDevices[marketData/operators/address/countryType/regionType/id='8']");
HEre is the exact stack trace:
