Spring Integration

[marcio.dantas]

Hi,

I'm integrating a spring application with Seam. The extended persistence context is working fine but I'm having issues with my spring annotated transactions (which worked before).

Caused by: org.springframework.dao.InvalidDataAccessApiUsageException: Write operations are not allowed in read-only mode (FlushMode.NEVER/MANUAL): Turn your Session into FlushMode.COMMIT/AUTO or remove readOnly marker from transaction definition.

This kind of problem occurs with write transactional methods that calls other annotated methods with propagation REQUIRES_NEW and read-only true. The session's flush mode gets setted to NEVER and when the global transaction continues to execute and flushes the error happens.

The question is: are the transactions really supposed to work as before or are there limitations?

Hello,

have you resolved this problem?
I'm facing the same issue and don't have a clue how to fix it.

Best regards
