How to add signature in JSP page

[bindhu80]

Hi,

I need to add a persons signature in my JSP page. If in that part if a pesrons scrolls the mouse a person can put his signature and on clicking submit it gets saved in DB . Is there any way to do so. How to add a part where we can add signature o mouse drag. Thanks in advance.

Explain the mouse drag part. Do you mean the person would write the signature using the mouse?

[bindhu80]

yes the person will write his signature using mouse drag.

[r035198x]

yes the person will write his signature using mouse drag.

Two questions for now

1.) What will the user be wrting on? Obviously just writing on a blank page won't work because the user can't see what they are writing.
2.) What datatype are you going to use in the database to store the .. eh signature?

we will be using clob datatype to store in the DB.
i dont understand your first question. if my understanding is correct.
when the user drags the mouse it will be show in the area which is meant for signature. the user can see it in our screen.

Will the signature be text or an image?

[bindhu80]

The signature will be an image

[r035198x]

You therefore can't store it using Clob then can you?
And you can't use the page for it either. You'd need some image creation software. The user would create the image by doing the drawing ...
Do you really need to have all those complications?

[bindhu80]

We dont want all those complications but the client requirement is so.

What would be the use for that signature? If I draw something on some paint program using the mouse, chances are that I'll never be able to draw the exact same thing again anyway. How would you check that the signature entered matches one in the database?

[bindhu80]

Its not used for verfication. we store it in DB and where ever that person information comes we will retrive that signature from DB.

Pls can some one help me.....

So it's just a picture created by the user that you store and display without making any checks for it?

[bindhu80]

yes you are correct....

I'd use an Applet (or JApplet) for the actual drawing and the communication back
to the host where the Applet came from. The Applet should send the data of the
Image over to the host that saves it in its database ready to be send back again
to a client machine for a particular user. The last part can be done using a JSP
page. Read Sun's tutorial on (J)Applets.

kind regards,
