GenericJDBCException: Loại cột không hợp lệ: getCLOB không được triển khai

Question

Tôi đang cố chuyển từ JBoss 5.1 sang JBoss 7.1.1 và hiện đang gặp sự cố này. Bất cứ khi nào tôi cố gắng để có được một đối tượng từ cơ sở dữ liệu có chứa một lĩnh vực CLOB, lỗi này được ném:

Tôi đang sử dụng ojdbc6.jar Oracle 11.2. người lái xe. Tôi đã thử với ojdbc5.jar, nhưng không thành công. Bất kỳ ý tưởng làm thế nào để sửa lỗi này?

Trong persistence.xml Tôi đang sử dụng Oracle10gDialect.

Answer 1

Dường như cột được đề cập không phải là CLOB, nhưng VARCHAR và trình điều khiển Oracle dường như không hỗ trợ getCLOB trên cột VARCHAR. Tôi căn cứ này trên một phần của stacktrace, nơi mà các tài xế riêng của mình một cách rõ ràng gọi một phương pháp unimpl (tôi giả sử để ném ngoại lệ) và rằng nó đề cập đến T4CVarcharAccessor:

Caused by: java.sql.SQLException: Invalid column type: getCLOB not implemented for class oracle.jdbc.driver.T4CVarcharAccessor 
    at oracle.jdbc.driver.Accessor.unimpl(Accessor.java:412) [ojdbc5.jar:11.2.0.1.0] 
    at oracle.jdbc.driver.Accessor.getCLOB(Accessor.java:1296) [ojdbc5.jar:11.2.0.1.0] 

Vì vậy, nó trông giống như định nghĩa của cột và các expections của Hibernate về việc sử dụng nó không phù hợp.
