Currently, I have a class which is read during startup. It reads the information fine.
@Startup
@Scope(ScopeType.APPLICATION)
@Stateful
@Name("propertyInfo")
public class PropertyInfo implements PropertyInfoLocal, Serializable {
@Logger
Log log;
@PersistenceContext(type = EXTENDED)
EntityManager em;
@Out
private String tmpDir;
@Create
public void initialize() {
String fileSep = System
.getProperty(SystemConstants.PROPERTY_FILE_SEPARATOR);
String homeDir = System
.getProperty(SystemConstants.PROPERTY_JBOSS_HOME_DIR);
String dukeProperty = homeDir + fileSep + "deploy" + fileSep
+ "artwork.ear" + fileSep + "artwork.war" + fileSep + "WEB-INF"
+ fileSep + "configuration.properties";
log.info("configuration Properties [#0]", dukeProperty);
Properties props = new Properties();
try {
FileInputStream fis = new FileInputStream(dukeProperty);
props.load(fis);
String tmpDir = props.getProperty("tmp.dir");
System.out.println(" ");
System.out.println("tmpDir --->> " + tmpDir);
System.out.println(" ");
} catch (FileNotFoundException ex) {
log.error("The 'configuration.properties' file is missing.");
} catch (IOException ex) {
log.error("Unable to read the 'configuration.properties' file.");
}
}
...
}
The problem is when I try to read this information from within another class. I have tried both:
PropertyInfo targetDir = (PropertyInfo) Contexts.getApplicationContext().get("propertyInfo");
and
PropertyInfo pi = (PropertyInfo) Component.getInstance(PropertyInfo.class);
These give me a classCastException.
Could someone tell me what I am doing wrong? Is there a better way of handling application settings?
