将图像标记的src属性中的变量值设置为javascript / ajax中的base64编码图像

Question

I have an image byte code base64 encoded which i am trying to set the tag's src attribute in the javascript/ajax.

I don't want to directly set it as i am getting this byte code from reading the response back from a servlet and taking the bytecode into a variable and want to set this variables value in the src attribute like following.

var src3="data:image/jpg;base64,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";
document.getElementById("outmessage").innerHTML = "<h2> Image \<img src\= "+src3+" /></h2>";

This doesn't work: gives me an output as

The thing i am sure about is that the base64 byte is correct as i tested it by adding directly to the src element of img tag like following

document.getElementById("outmessage").innerHTML = "<h2> Image \<img src\= "+src3+" /></h2>";

The above works in the browsers (ie/firefox etc). i was running the same pieces of code through eclipse (deploying on tomcat) and was checking the result page on eclipse default browser.There it was not displaying the image. When i ran the same url in firefox or chrome,it displayed the image. I guess some problem with eclipse default browser not being able to show the image
