Better way how to get list of all classpath URLs in runtime

Hello everyone,
How to get list of all classpath items (URLs) in runtime from Java code?
I am aware of solution based on System.getProperty("java.class.path"). Is there any alternative?
This solution has several drawbacks. You have to parse String output. And I not sure if it contains ALL resources (JARs, class directories) loaded by ClassLoader or just reflects -cp arguments.
Does system property "java.class.path" contain ALL loaded JARs?
Does it contain items (JARs, class directories) loaded by bootstrap classpath?
What about JARs loaded in runtime?
Is the separator ":" always same on all operation systems?
I was looking for some Java API based solution, method like List<URL> getAllClasspathItems()
But there is nothing like this in ClassLoader, Class, Runtime or System classes.
For curious, here is code I use.
String classpath = System.getProperty("java.class.path");
StringTokenizer st = new StringTokenizer(classpath, ":");
while (st.hasMoreElements()) {
System.out.println(st.nextElement());
}

For curious, here are output prints for all 3 methods:
1) parsing system property
2) tschodt
3) overcast SystemClassLoader to URLClassLoader

...Interestingly, method 1 and 3 gives the same list, same order, same count, just format of item is a little bit different. The order is same as in Eclipse .classpath file.
Method 2 (tschodt) give significantly more items! rougly 3x! Different order (somewhat random it seems to me). Some items contain extra information, like version and string "Java Platform API Specification".
It prints not absolute paths but logical Java names.

How to get list of all JSF beans

How can one get a list of all JSF beans?
To get a particular JSF bean one does
   static public Object findJSFBean(String beanName)
      FacesContext fc = FacesContext.getCurrentInstance();
      if (fc== null) return null;
      ELContext elContext = fc.getELContext();
      Application app = fc.getApplication();
      ELResolver elResolver = app.getELResolver();
      Object result = elResolver.getValue(elContext, null, beanName);
      return result;

Several ways:
1) Store some key in the request scope indicating the "id" of the wizard.
2) Use a single session scoped bean which references all related session scoped beans so that you have a single main point of reference.
3) Consider conversation scope. Apache Orchestra and JBoss Seam have their solutions.1. Can you elaborate on this?On start of the wizard generate/assign some unique identifier which you pass to the next request everytime as a hidden parameter. Use this identifier to identify a separate 'wizard conversation scope'.
2. Yeah, this might work. But I'd need to have a common entry point (such as overriding doPost of the default faces servlet) to destroy the wizard bean whose pages have ended, which means hardcoding page names in my java code. Also, my wizard would have to register itself in this map. That's why this solution seems very much like what I was asking for originally -- that is, the session bean has a list of all wizard beans in it.Just destroying the session bean at its own ought to be sufficient. E.g. externalContext.getSessionMap().put("managedBeanName", null); destroys the session scoped bean associated with the specified managed bean name.
3. This is the ideal solution. Unfortunately, the documentation is not very good, and I could not find examples. Hopefully this will make its way into JSF 3.0.Can't help any much with this further.

How to get list of all the dates between two dates

Hi, Can anybody please help me ..
I have two dates in string format ("dd/MM/yyyy).I need to get all the dates in between these two dates.How can I do thin in java
Thanks in advance

Look at classes Calendar and SimpleDateFormat.
And get your abstraction straight: you don't have two dates. You have two Strings that represent a date. To use them, you have to convert them to Date objects first with SDF.

How can get emails on all devices?

How can get emails on all devices? When I read an email on my mac, my iphone doesn't download it. How can I change that setting?? I need to have all emails and all my devices!

It sounds like your using a POP3 email account versus IMAP. With a POP3 account if you do not have the settings configured to leave email on the server the problem you describe will occur. With Outlook 2010 (on a PC for example) you can go into the account settings and configure to leave email on the server. That way both devices will see the email. Check help for your Mac email program for instructions...
http://www.serverintellect.com/support/email/outlook-leave-on-server/
A better solution is if your email provider uses IMAP. IMAP sync email folders between multiple devices. Meaning any device will receive the email, all sent email can be seen on the devices. If you delete email from one device the email is deleted from all the other devices. Check with your email provider to see if they offer IMAP services.
If they do not your choices are to 1) configure email on the Mac as illustrated in the link above or 2) change email providers to something like Gmail or Outlook.com (as examples).
Also see this for the iPad...
Using a POP account with more than one device - Apple Support
FWIW I use Cox IMAP email and fully sync email between a Win 8.1 Update 1 laptop, a Win 7 desktop, an iPad 4, an iPhone 4 and an iPhone 5S.
