Display image from the binary data in form of String in a JSP

[binu narayanan]

Hi Everybody,

I have a String with image in Base 64 encoded binary format. I would like to display the same in a JSP. Kindly guide me how to achieve this.

The string with data say

[ridiculously long Base64 string removed]

Kindly help me in achieving this

1. absolutely nothing was served by posting that whole monster string.
2. There is no reliable way to serve binary data from JSP, JSP assumes character data
3. each image on a HTML web page takes a separate request in an IMG tag
4. in a JSP you must create a URL for an IMG tag that points to a servlet which can serve the binary data with correct headers for type and content-length

Hi Bill,

I just came across this piece of code for achieving what i had asked earlier

The value of the strImage is the monstrous value of the image in binary format.

  <img src="data:image/gif;base64,<%=strImage%>" alt="test" width="951" height ="197"/>  

Can you give an idea of how the servlet can help me get the image on the fly in a jsp

Thank you

Binu

This Wikipedia article discusses the use of "data" in IMG tag URLs - apparently it is not universally supported so you risk failure for some users.

Hi Bill,

Thanks for the info.

Could like to get a little bit of help in creating a servlet to render the base 64 encoded binary string.
