load spring application context from string

Can somebody show me how to use Spring to load application context through xml string instead of file or classpath resource?

Thanks,

Haven't tried it so far but can probably give a try:

// define and open the input stream from which we read the configuration
InputStream input = new ByteArrayInputStream("string".getBytes("UTF-8"));
// create the bean factory
DefaultListableBeanFactory beans = new DefaultListableBeanFactory();
XmlBeanDefinitionReader reader = new XmlBeanDefinitionReader(beans);
reader.setValidationMode(XmlBeanDefinitionReader.VALIDATION_XSD);
reader.loadBeanDefinitions(new InputStreamResource(input));
beans.preInstantiateSingletons();
input.close();

@Ref: http://beradrian.wordpress.com/2010/03/30/load-spring-from-input-stream/ Let me know if it works...

Use this:

String contextXML = ...;
Resource resource = new ByteArrayResource(contextXML.getBytes());
GenericXmlApplicationContext springContext = new GenericXmlApplicationContext();
springContext.load(resource);
Object myBean = springContext.getBean("myBean");
...

i found a way doing it.

public MyApplicationContext(String xml,
        ApplicationContext parent){

    super(parent);

    this.configResources = new Resource[1];

    configResources[0] = new ByteArrayResource(xml.getBytes());


    refresh();
}


private Resource[] configResources;

protected Resource[] getConfigResources() {
    return this.configResources;
}
