javac can't find XmlBeanFactory

[BillyBob10000]

here is the classpath:

C:\>set classpath=.;C:\;D:\;
C:\SpringFramework-2.0\dist\spring.jar;
C:\spring-framework-2.0\lib\jakarta-commons\commons-logging.jar;
C:\com\springinaction\chapter01\hello\

here is the compilation command

C:\>javac com\springinaction\chapter01\hello\HelloApp.java


here is the result - can't find the XmlBeanFactory

com\springinaction\chapter01\hello\HelloApp.java:1 1: cannot find symbol
symbol : constructor XmlBeanFactory(java.io.FileInputStream)
location: class org.springframework.beans.factory.xml.XmlBeanFacto ry
BeanFactory factory = new XmlBeanFactory(new FileInputStream("hello.xml"));
^
1 error

Anyone have an idea what is wrong?

Thanks,

Bill

Well, the class XmlBeanFactory has been found, actually. What is missing is the constructor taking an InputStream, and indeed such a constructor does not exist (at least not in recent versions of Spring).

You may replace the line equivalently with

BeanFactory factory = new XmlBeanFactory(new InputStreamResource(new FileInputStream("hello.xml")));

Thanks for your help, Andreas

I added the import for InputStreamResource and the program runs.
It does complain about not finding org/apache/commons/logging/LogFactory
but I will work on that for a while. I beleive I need to download another
software package.

Well, I found that I needed additional jar in the classpath to support logging.
And now it emits another error, see below:

import org.springframework.core.io.InputStreamResource;

GreetingService greetingService = (GreetingService) factory.getBean("greetingService");
greetingService.sayGreeting();
}
}


I interpret this to be a problem with the 'hello.xml' file being open. But I am
not sure what is meant by open in this context - the file is not open by any
other applications. The exception is being thrown by the statement:

BeanFactory factory = new XmlBeanFactory(isr);

which is passed in the filename as a resource.

Any ideas where to go next?

Thanks in advance,

Bill.

I found the problem. Looking at the code for XmlBeanFactory showed that
it throws the exception I was seeing if it is passed an open file and
the function FileInputStream opens the file. Changing to another
function - FileSystemResource - looks like it returns the file as a resource
but does not open it. The modified code is below...

package com.springinaction.chapter01.hello;

import java.io.FileInputStream;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFacto ry;
import org.springframework.core.io.FileSystemResource;

public class HelloApp
{
public static void main(String[] args) throws Exception
{
FileSystemResource fsr = new FileSystemResource("hello.xml");
BeanFactory factory = new XmlBeanFactory(fsr);
GreetingService greetingService = (GreetingService)factory.getBean("greetingService" );

greetingService.sayGreeting();
}
}

And the output...

Buenos Dias!

So now a working example I can understand.
