Application URL differences in 7.0 and 7.3

Hi All,

We are able the call the images from one jsp file to another jsp file using abstart portal component in 7.0 using the following code.

<img src="/irj/portalapps/com.test.aboutimage/images/AboutImage.png" />

But in 7.4 it is not allowing to fetch the image when i specify the above code.

If i use the absolute path like <img src="com.test.aboutimage/images/AboutImage.png" /> then the image was displayed successfully.

The same url is not allowing me to get any .CSS values from one project to another project .

Please somebody let me know what the URL differences in 7.0 and 7.3 onward.

How can i access the the URL for 7.3 portal applications.

Thanks & Regards,
