Question

如何解决以下openjpa错误。

“尝试提交null javax.transaction.Transaction。如果发生回滚，某些应用程序服务器会将事务设置为null。”

我看到类似的错误here，但没有任何评论。

OpenJPA属性

"openjpa.TransactionMode", "managed"
"openjpa.Log", "commons"
"openjpa.ManagedRuntime", new JpaTxMgrProvider(_tm)
"openjpa.ConnectionFactory", _ds
"openjpa.ConnectionFactoryMode", "managed"
"openjpa.jdbc.TransactionIsolation", "read-committed"
"openjpa.FlushBeforeQueries", "true"

我正在运行使用嵌入式Tomcat的独立服务器。

我不期待一个解决方案，但有一些指针可以解决这个问题。

谢谢， Waruna

我有同样的情况：

Caused by: <openjpa-2.2.2-r422266:1468616 nonfatal user error> org.apache.openjpa.persistence.InvalidStateException: Attempt to commit a null javax.transaction.Transaction.  Some application servers set the transaction to null if a rollback occurs.
at org.apache.openjpa.kernel.BrokerImpl.setRollbackOnlyInternal(BrokerImpl.java:1664)
at org.apache.openjpa.kernel.BrokerImpl.setRollbackOnly(BrokerImpl.java:1650)
... 26 more

如果你的persistence.xml有这样的属性：

    <properties>
        <property name="openjpa.jdbc.SynchronizeMappings" value="buildSchema(foreignKeys=true)"/>
    </properties>

然后openjpa从你的jpa-classes和表OPENJPA_SEQUENCE_TABLE生成所有表（非常重要!!!）。

如果没有属性“openjpa.jdbc.SynchronizeMappings”，则不会生成表OPENJPA_SEQUENCE_TABLE，并且您在openjpa-log中会遇到一些例外情况：

fatal store error> org.apache.openjpa.util.StoreException: Table "OPENJPA_SEQUENCE_TABLE" not found; SQL statement:
SELECT SEQUENCE_VALUE FROM PUBLIC.OPENJPA_SEQUENCE_TABLE WHERE ID = ? FOR UPDATE [42102-174] {SELECT SEQUENCE_VALUE FROM PUBLIC.OPENJPA_SEQUENCE_TABLE WHERE ID = ? FOR UPDATE} [code=42102, state=42S02]
    at org.apache.openjpa.jdbc.sql.DBDictionary.narrow(DBDictionary.java:4962)
    at org.apache.openjpa.jdbc.sql.DBDictionary.newStoreException(DBDictionary.java:4922)
    at org.apache.openjpa.jdbc.sql.SQLExceptions.getStore(SQLExceptions.java:136)
    at org.apache.openjpa.jdbc.sql.SQLExceptions.getStore(SQLExceptions.java:110)
    at org.apache.openjpa.jdbc.sql.SQLExceptions.getStore(SQLExceptions.java:62)
    at org.apache.openjpa.jdbc.kernel.AbstractJDBCSeq.next(AbstractJDBCSeq.java:66)

编辑：尝试手动添加此表：

CREATE TABLE OPENJPA_SEQUENCE_TABLE
(
    ID TINYINT PRIMARY KEY NOT NULL,
    SEQUENCE_VALUE BIGINT
);
