It will scan the directiory(ies) for hbm.xml files and read them the same way as if you had explicitly listed them. I don't think performance is an issue.

Whenever you declare a BigDecimal, initialize it like this:


private BigDecimal amount = new BigDecimal("0.00");

and rerun your test.

Nothing to do with the 0 you pass.
It's just that you call it with an int parameter

I guess the problem is in your java code and not the db columns.

Since the only code sample you give is the field declaration I only can say that the following line

I came across the same issue recently when upgrading Hibernate and found this problem with javassist.

Using instanceOf solves the problem, however it breaks the symmetry contract of the method: ...

MappingResources can only receive paths relative to your classpath.

Try this :

I think another question you should ask yourself is "why is the other process locks data? Is there a good reason for doing this, and if not can I lower the isolation level of the other transaction...

@Luke
I checked it again and you are right, there is no side-effect.

You checked which jar file?
In spring 3 the whole jar structure has been re-organized. There is no all-in-one spring.jar as before. You have to pick what you need.

When using "select" in HQL, hibernate considers it a projection query and your find method returns a List of Object[] not of User objects. Your jsp then uses the dot notation on an array.

You need
<form:errors path="name"/> to display the error messages

A simple approach is to prefix all controller-handled urls under a path element which is not related to any directory structure e.g. "services"

In some cases Spring can configure the underlying layer for better performance when a transaction is declared as read-only. When you use Hibernate for example, it sets the flush mode to FLUSH_NEVER...

There is an improvement request in jira regarding this -but with low priority. Seems to be added in 3.1.

Ah, you are using JPA, so you are right, select is not optional like HQL.
Check to see what your find method returns. I guess it is a list of Object[]. In that case your get(0) returns an array...

Remove "SELECT s" from your query.

Have you considered using a manual flush in the hibernate session just after the first deletion? This overrides the write-behind behaviour that hibernate applies.

Yes and no. In fact to check your case I changed this mapping:


<prop key="manager/admin/hotel/report/users">userListController</prop>

to


<prop...

They are definitely still supported. I'm also in spring 3 and have no issue on this. Are you sure you have not misspelled something on the mappings?
