The question is on getting values from html page through servet;
Post.Html



PostTest.java



values 500 and 600 are enterd in html page and what would be the output.


I am getting the error. " java.lang.IllegalStateException: Reader already obtained"

The correct answer in the WhizLab dump is
Value obtained manually = value1=500&value2=600&AddButton=Submit+Query Value obtained again manually = null Value obtained again = null Value obtained again = null.

Can anyone of you help me to understand, what is this error "Reader already obtained" explains?

Did you try this in WebSphere App Server? There is a bug in their container implementation, i don't know why this is not fixed yet. Here is the reference to that http://publib.boulder.ibm.com/infocenter/wasinfo/v4r0/index.jsp?topic=/com.ibm.support.waszos40.doc/html/WebSphere_Application_Server_for_z_OS/swg1PQ80846.html

If you try the same in tomcat you would see the expected result.

thanks
