Hi all,
these days I'm trying to change a BMP entity in a CMP.
I had strictly no problem with my CMP but I want to explore the BMP possibilities and
performances.
But It seems I have a problem with the CLOB field of my bean:
- No data is retrieve when loading loading the BMP
- An exception is thrown upon insertion of long string in the CLOB field:
javax.ejb.EJBException: Internal error setting parameters for field content;
CausedByException is:
| Data size bigger than max size for this type: 7115570

org.jboss.ejb.plugins.CMPPersistenceManager.createEntity(CMPPersistenceManager.java:253)

Environment:
- JBoss 3.0.8
- Oracle 8.1.7
My Bean:
/**

| * name="LogItem"
| * view-type="both"
| * type="CMP"
| * primkey-field="id"
| * cmp-version = "2.x"

| * table-name="LOGDATA"

| * remove-table = "false"
| *
| */

| public abstract Long getId();
| public abstract void setId(Long id);
|
| /**

| public abstract void setContent(String content);
|
| /**

| * column-name = "LOGDATA_TYP"
| * jdbc-type = "VARCHAR"
| * sql-type = "varchar(300)"
| */
| public abstract String getType();
| public abstract void setType(String type);
|
| //==========================================
| // CMR fields

|
| //==========================================
| // EJB Callbacks
| //==========================================
| /**
| * @ejb.create-method
| * view-type = "both"
| */
| public Long ejbCreate( ... )throws CreateException{
| ...
| return null;
| }
| public void ejbPostCreate( ... )throws CreateException{
| }
| }

Can someone tell what I am missing or if there is a problem with this kind of stuff
(and it's workaround).
Best regards,
Alban.
