[jira] [Commented] (OPENJPA-2344) You cannot invoke other
java.sql.Clob/java.sql.Blob methods after calling the free() method or
after the Blob/Clob's transaction has been committed or rolled back.
[ https://issues.apache.org/jira/browse/OPENJPA-2344?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13590854#comment-13590854 ]
Kevin Sutter commented on OPENJPA-2344:
---------------------------------------
It's not the free'ing of the Blob/Clob, I believe it's the free'ing of the Connection. OpenJPA does perform Connection.free() as part of its Connection close processing. Googling this type of error shows that Derby did have several issues with their earlier releases relating to their Locator service and Blobs/Clobs. Hopefully, those have since been resolved with the 10.8.2.2 release.
But, the free'ing of the Connection still may be something you need to be aware of due to their implementation. As a test, you could try a different OpenJPA ConnectionRetainMode [1]. The default is on-demand, which may be closing the connection before you have had a chance to access your Blob/Clob fields. You could try transaction mode, or even always mode to see if it gives you better results.
Let's see if this helps before figuring out the next step(s). Thanks.

> Hi,
> We have a problem with OpenJPA (2.2.1) and Derby (10.8.2.2, in server mode). Some of our entities use blob fields to store binary data, and clob for long string values. When we start our software and executing a query on the database like "select e form {entity} e" we get this type of stacktrace :
> <openjpa-2.2.2-QFD-r422266:1446687M fatal general error> org.apache.openjpa.persistence.PersistenceException: You cannot invoke other java.sql.Clob/java.sql.Blob methods after calling the free() method or

> We tried default openjpa properties configuration but nothing change. We also looked into OpenJPA to find calls on Blob/Clob free() method, unsuccessfully... Is it normal to not explicitly free blob/clob fields after reading values ? In any event, I will tried to write a unitary test as soon as possible.
