Here is one more line of the stack trace.
[CODE]
java.lang.NullPointerException
at java.util.Properties$LineReader.readLine(Properties.java:418)
at java.util.Properties.load0(Properties.java:337)
at java.util.Properties.load(Properties.java:325)
at
snaq.db.ConnectionPoolManager.loadProperties(ConnectionPoolManager.java:278)
at
snaq.db.ConnectionPoolManager.getInstance(ConnectionPoolManager.java:167)
at
snaq.db.ConnectionPoolManager.getInstance(ConnectionPoolManager.java:221)
at com.******.<init>(*******.java:23)
[/CODE]
which correlates to this method
[CODE]
try
{
connMgr = ConnectionPoolManager.getInstance(); //THIS IS LINE
23
}
catch (Exception e)
{
e.printStackTrace();
}
[/CODE]
The init method is the following
[CODE]
InputStream is = getClass().getResourceAsStream("/db.properties");
Properties dbProps = null;
try {
dbProps = new Properties();
dbProps.load(is);
}
catch (Exception e) {
System.err.println("Can't read the properties file. " +
"Make sure db.properties is in the CLASSPATH");
return;
}
loadDrivers(dbProps);
createPools(dbProps);
[/CODE]
