    <p>How do I cure the cause of the occasional exception <code>IllegalArgumentException occurred while calling setter</code> that Hibernate throws when my program attempts to load a user by name from the database?</p> <p>Am I incorrectly mapping column <code>USER_RV</code> in table <code>User</code> to class <code>Integer</code> instead of <code>BigDecimal</code> or some other integer type? Note that the same application maps <code>NUMBER</code> columns in other tables to <code>Integer</code> objects, but Hibernate <strong>does not</strong> throw this exception when populating an object with a row from those tables.</p> <p>Further note that the program enables <strong>RMI cache replication</strong> for the <strong>User cache only</strong>. Might this exception be related to cache replication? Is it a bug in Ehcache or Hibernate?</p> <pre><code>Caused by: org.springframework.orm.hibernate3.HibernateSystemException: IllegalArgumentException occurred while calling setter of

    1. COAfter disabling RMI cache replication, the program no longer throws this exception, so it appears that there is some issue with Ehcache or Hibernate.

    2. COI went ahead and deleted my answer, as Pascal answered it the same way, and you seem to have found a different problem. I have never used the RMI cache replication, so I don't have a lot of help for you there. I would guess it is likely a problem in the RMI replication code, rather than EHCache directly.

    3. COaperkins, thank you for your answer attempt. Will let you know the solution should I hear back from Terracotta or the Hibernate community.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
