Strange Spring problem

[Vassili Vladimir]

Hi,

I'm getting a strange compilation error while trying my first Spring applications, where I'm passing a reference to a FileInputStream to the constructor of an XmlBeanFactory. It's saying that constructor is not found!

Can anybody tell me what can be the problem ?

Thanks in advance ...

Let me peak into my crystal ball and see if I can read your code from here. Man, this is tough. It's pretty cloudy. I wish there was an easier way. My crystal ball just isn't working right.

Ok, how about you post your relevant code/configuration here so I can let my crystal ball take a break.

[Vassili Vladimir]

lolllll

Here it goes:

    
try
{
FileInputStream file = new FileInputStream( "test.xml" );

BeanFactory beanFactory = new XmlBeanFactory( file );


}
catch ( IOException ioException )
{
System.out.println( ioException.getMessage() );
}

Thanks in advance ...

Can you post the stack trace as well as your test.xml file as well? We need all the information.

[Gregg Bolinger]

Of course, it could be because XmlBeanFactory doesn't accept a String as a constructor argument.

http://www.springframework.org/docs/api/org/springframework/beans/factory/xml/XmlBeanFactory.html#XmlBeanFactory(org.springframework.core.io.Resource)

You don't need a crystal ball to find that out

[Vassili Vladimir]

I'm not passing a String, I'm passing a reference to a FileInputStream ...

[Christophe Verré]

I'm passing a reference to a FileInputStream

The problem is that there's no such constructor for the XmlBeanFactory. Use a FileSystemResource instead :

Resource resource = new FileSystemResource("beans.xml");
BeanFactory factory = new XmlBeanFactory(resource);

Hi,

I used FileSystemResource and it's giving me the following exception:

    
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory

Commons logging from apache jakarta is missing on your classpath.
There is quite a bunch of libraries, spring depends on.
Download the with-dependencies thing (for example: http://sourceforge.net/project/showfiles.php?group_id=73357&package_id=173644&release_id=538515)
You dont need any of those jars for a little project. Newer books tend to start with a short introductions about when which jar is needed. Currently I can't find such information online. Of course for starting you may put all jars from the with-dependencies download in your classpath. Or start with spring.jar and add those which are missing.

I have included the apache commons API in my classpath, but yet another problem raised now , here it is:

    
Line 4 in XML document from file test.xml is invalid; nested exception is org.xml.sax.SAXParseException: Document root element "beans", must match DOCTYPE root "null".

and here's my test.xml file

    
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans <a href="http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">" target="_blank" rel="nofollow">http://www.springframework.org/schema/beans/spring-beans-2.0.xsd"></a>

<bean id="myBean" class="vassili.MyBean">
<property name="name">
<value>vassili</value>
</property>
</bean>

</beans>

Can anybody tell me what's going on ? I'm so confused about this

Thanks in advance ...

hi Vassili,
Try working with the DTD in place of schema to the spring context file.

use this--

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<beans>
........
.......
</beans>

I think that will work.
bye

[Vassili Vladimir]

It worked

Thanks alot
