休眠/ ORACLE /春：值java.sql.SQLException：違反協議

Question

能否請你幫我，當我嘗試使用Hibernate /甲骨文10.2我有以下錯誤執行更新HQL：

我使用Java 1.6 。

在我的行家：

<dependency> 
<groupId>com.oracle</groupId> 
<artifactId>ojdbc14</artifactId> 
<version>10.2.0.4.0</version> 
</dependency> 
<dependency> 
<groupId>org.hibernate.javax.persistence</groupId> 
<artifactId>hibernate-jpa-2.0-api</artifactId> 
<version>1.0.1.Final</version> 
</dependency> 

例外：

Caused by: org.springframework.transaction.TransactionSystemException: Could not roll back JPA transaction; 
Caused by: org.hibernate.TransactionException: rollback failed 
Caused by: org.hibernate.TransactionException: unable to rollback against JDBC connection 
Caused by: java.sql.SQLException: Protocol violation 

感謝。

我找到了解決方案。 我已經改變了我的代碼，只刪除級聯屬性：

@OneToMany(fetch = FetchType.LAZY, mappedBy = "scheduleRequest", cascade = CascadeType.ALL) 
public Set<AdhocDetail> getAdhocDetails() { 
return this.adhocDetails; 
} 

到：

@OneToMany(fetch = FetchType.LAZY, mappedBy = "scheduleRequest") 
public Set<AdhocDetail> getAdhocDetails() { 
return this.adhocDetails; 
} 

感謝。
