[jira] [Commented] (OPENJPA-2906) ClassCastException - java.lang.Long incompatible with java.lang.String
[ https://issues.apache.org/jira/browse/OPENJPA-2906?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17719634#comment-17719634 ]

-------------------------------------------
Hello [~adityah],
sorry for being silent (was busy with other projects)
According to Stacktrace:
{code}
Caused by: java.lang.ClassCastException: java.lang.Long incompatible with java.lang.String
at org.apache.openjpa.kernel.DetachedStateManager.attach(DetachedStateManager.java:260)
{code}
The error happens here https://github.com/apache/openjpa/blob/2.2.0/openjpa-kernel/src/main/java/org/apache/openjpa/kernel/DetachedStateManager.java#L260
It seems field is declared as String in the DB, so the value is casted to String
Can you check your DB?
in case DB field is declared correctly, could you please provide some sort of small demo application demonstrating the problem?
So I can debug?
BTW version 2.2.0 seems to be very old and vulnerable: https://mvnrepository.com/artifact/org.apache.openjpa/openjpa
Maybe you can switch to newer version? :)
