I need to initialize a set of static String values stored in an XML files [ I know this is against the EJB spec ] as shown below since the over all Idea is to not hardcore within EJB's the JNDI info
Utils.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd">
<properties>
<entry key="jndidb">java:jdbc/MYSQLDB10</entry>
<entry key="jndimdbque">java:jms/QueueName/remote</entry>
<entry key="jndi1">DBConnections/remote</entry>
<entry key="jndi2">AddressBean/remote</entry>
</properties>
The Onload of ejbserver startup code is as follows ... inpstrem = clds.getClassLoaders(flename) Reads the Util.xml and stores the same in Hashtable key value pare....
package com.ejb.utils;
import java.io.InputStream;
import java.util.Enumeration;
import java.util.HashMap;
import java.util.Hashtable;
import java.util.Map;
import java.util.Properties;

@Singleton
@Startup
public class StartupUtils {
private final String INITFILENAME = "/System/Config/Utils.xml";
private static Hashtable HTINITFLENME=null,HTERRINITFLENME=null,HTCMMNFLENME=null;
public StartupUtils() {
HTINITFLENME = new Hashtable();
HTERRINITFLENME = new Hashtable();
}
public void printAll(Hashtable htcmmnflenme){
Enumeration ENUMK = null, VALS = null;
String KEY = "", VALUE = "";
ENUMK = htcmmnflenme.keys();
while (ENUMK.hasMoreElements()) {
KEY = null;VALUE = null;
KEY = (ENUMK.nextElement().toString().trim());
VALUE = htcmmnflenme.get(KEY).toString().trim();
InitLogDisplay(KEY + " :::: " + VALUE);
}
}
public static void InitLogDisplay(String Datadisplay){
System.out.println(Datadisplay);
}
public Hashtable getDataProp(String flename){
Map htData = null;
InputStream inpstrem = null;
ClassLoaders clds = null;
Enumeration enumk = null, vals = null;
String key = "", value = "";
Properties props = null;
Hashtable htx = null;
try {
clds = new ClassLoaders();
inpstrem = clds.getClassLoaders(flename);
props = new Properties();
props.loadFromXML(inpstrem);
enumk = props.keys();
vals = props.elements();
htData = new HashMap();
htData = new TreeMap();
while (enumk.hasMoreElements()) {
key = (enumk.nextElement().toString().trim());
value = (vals.nextElement().toString().trim());
htData.put(key,value);
}
clds = null;
props = null;
inpstrem.close();
} catch (Exception e) {
e.printStackTrace();
}finally{
key = ""; value = "";
enumk = null;vals = null;
clds=null;
props=null;
}
htx = new Hashtable();
htx.putAll(htData);
return htx;
}
public void setUtilsPropDetails(){
HTINITFLENME = getDataProp(INITFILENAME);
this.printAll(HTINITFLENME);
}
public static Hashtable getUtilsPropDetails(){
return HTINITFLENME;
}
@PostConstruct
public void startOnstartup(){
this.setUtilsPropDetails();
this.printAll();
}
@PreDestroy
public void startOnshutdown(){
try {
this.finalize();
} catch (Throwable e) {
e.printStackTrace();
}
}
}
On startup of EJB server "this.printAll(HTINITFLENME);" prints the key values of the XML file hoever If an external Call is made via any other EJB's to the method "getUtilsPropDetails()" does not return the key values....
Am i doing something wrong ??????
