It happens to the form view on initial load..

Yes, I did, however, I get the following exception in my JBoss window:

I am new to Spring MVC, and I can't seem to figure out what is the problem. I get the following exception: Neither BindingResult nor plain target object for bean name 'loginUser' available as request attribute. Here are my files: web.xml, ...-servlet.xml and LoginController.java

I think, I messing up in the web.xml or ...-servlet.xml while defining my urlMapping, because if I change the following line to: <entry key="/" value-ref="loginController" /> the login page come up. Thank you in advance

my java,class and xml files are under

When I compile the java files everything is fine.
When I run the application I get the following error :
net.sf.hibernate.HibernateException: hibernate.cfg.xml not found.
In my code I have specified
private static String CONFIG_FILE_LOCATION = "/hibernate.cfg.xml";

try removing forward slash from the location, i.e.
private static String CONFIG_FILE_LOCATION = "hibernate.cfg.xml";

I am trying to use Hibernate annotations for mapping and I get following error:
org.hibernate.AnnotationException: Cannot find the expected secondary table: no servers available for annotated.Server
Here is my code:

I am using Derby as my database and I know I am getting connection to it...
any help would be appreciated...

But doesn't your configuration say it's in a directory called "database" under that?

I moved both my xml and pojo out of it, just to make sure that directory structure was not affecting anything...

Paul Clapham wrote:So no matter what you put in servers.hbm.xml, you still get the same error? (Hint: try putting rubbish in it.) If so, that simply means that Hibernate can't find it.

That might be the case... I did put some random tags and still got the same error... What is confusing to me if it can't find it, why??? I moved it to the source directory [where my hibernate.cfg.xml and derby.cfg.xml are located] and still the same error persist... The only other thing, I had an exception before that told me specifically that it could not find the mapping class (which was different exception from what I am getting now). I was getting "not found" exception when I wrongly specified path in hibernate.cfg.xml file to the mapping.

I removed everything from the servers.hbm.xml to look like this:
<?xml version='1.0' encoding='utf-8'?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="database"> <class name="Server" table="servers"> <id name="masterKey" type="java.lang.String" column="master_key"> <generator class="assigned"/> </id> </class> </hibernate-mapping>
and adjusted my POJO accordingly (to have only one String of masterKey). It still throws the error... I don't think there is a problem with form and validity of xml's themselves, because if I remove the line
<mapping resource="database/servers.hbm.xml"/>
from derby.cfg.xml, I get the connection and I am able to query database, and bring results back....

No, it was a typo when I was writing a post...

Got you, its just a typo...

Hey guys,
I am new to Hibernate (couple days). I got this error while running my program:
org.hibernate.InvalidMappingException: Could not parse mapping document from invalid mapping

Now I have looked on internet and none of the solutions seems to help me. Here is my files:
derby.cfg.xml
<?xml version='1.0' encoding='utf-8'?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory name="testDatabase"> <property name="connection.driver_class">org.apache.derby.jdbc.EmbeddedDriver</property> <property name="connection.url">jdbc:derby:HibernateTestDB</property> <property name="connection.username"></property> <property name="connection.password"></property> <property name="connection.pool_size">5</property> <property name="dialect">org.hibernate.dialect.DerbyDialect</property> <property name="current_session_context_class">thread</property> <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property> <property name="show_sql">true</property> <mapping resource="database/servers.hbm.xml"/> </session-factory> </hibernate-configuration>

servers.hbm.xml
<?xml version='1.0' encoding='utf-8'?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="database"> <class name="Server" table="servers"> <id name="masterKey" type="java.lang.String" column="master_key"> </id> <property name="ipAddress" type="string" column="ip_address" not-null="true"/> <property name="name" type="string" column="name" /> </class> </hibernate-mapping>

and my POJO:
Server.java
package database; public class Server { private String masterKey; private String ipAddress; private String name; Server() { } public String getMasterKey() { return masterKey; } public void setMasterKey(String masterKey) { this.masterKey = masterKey; } public String getIpAddress() { return ipAddress; } public void setIpAddress(String ipAddress) { this.ipAddress = ipAddress; } public String getName() { return name; } public void setName(String name) { this.name = name; } }

Now the only thing that might be different from everybody else, is that I am using IntelliJ IDEA 7.0.4 as my development tool...
Thank you, any suggestions would be highly appreciated...

I have a Base64 byte[] that contains a picture, that is 240x180 and is 88k. I was wondering if there is a way to change the color depth of this picture, so that the resolution stays the same, but the size of the picture goes down??? Thanks in advance
