I am trying to build a java application which needs to do drag and drop some elements in to the canvas and connect them with different types of connectors depending on selection etc. In one line something like what MS Visio does, but at the very basic form.

So my question is does Java Swing has any built in library/component to do this ?

What other facility/library can I get from Java core or any other java libraries to achieve this ?

Thanks in advance,
Jithu

Ok. I think I found the solution for my question.
The TOS field of IP header is modifiable by using the method setTrafficClass() of java.net.Socket class.

Thanks,

Hello Experts,

I was trying out a java networking application and was wondering, is there a way in java where I can change the value of TOS field of IP layer when Iam sending some UDP packets from my application.
Though Java Doc mentions this field as unused. This is getting more popular now as DSCP and modifying this is becoming important based on the type of data on whether it is real time data like voice/video.
So is there a way to modify this value in the data that I would be sending from my application.

Just for information, the below link would clarify the importance of this field

Thanks in advance.

Hi Peer,
Just wanted to say thanks for your input.

Today I passed SCDJWS with 97% and all that I used to prepare were
1. RMH
2. MZ guide
3. MZ quiz (Thanks a ton MZ, keep up the good work)

I wanted to go through Blue prints too but didnt have enough time to brush it. I feel the only improtant thing from Blue prints which is not in RMH is the web services layers and their demarcation and fuctionaity. Which is sufficiently covered in MZ quiz.

I did try xyzws.com mock but for some reason didnt like it and stopped it with one mock exam and used that time to go through MZ guide and quiz once again.

Hope this info helps for new takers for exam.

One advise I would like to say any one taking this exam is, dont spend too much time as you might feel that the sylabus is exhaustive. And if you finish RMH and MZ that is sufficient. The missing things in RMH like security, JAXB are covered in MZ guide.

Thanks to God ( for giving me question from what I read) , MZ and Peer.

Thanks and Regards,
Jithu

Hello all,

Yesterday I passed my SCJP with 91% and planning to continue with next level of certification and then proceed with SCEA.

I liked SCDJWS and thought of taking that next. But require advise from you all whether it is the preferred path or do I need to do SC[B|W]CD before going ahead for SCDJWS ?

What is the usual advised path ?

Thanks and Regards
