Hi.
We are having a small problem with out Servlets after we started porting all Projects to Weblogic 8.1 from 5.1... The below mentioned servlet code-segment works well in both 5.1 & 8.1 , except for 1 small diference... The 'null' appears as a String in Weblogic 8.1, and as ' ' in 5.1, We have developed many thousands of servlets around this concept. Is there any way we can display that annoying 'null' string as ' ' in Weblogic 8.1 (just like in the Weblogic 5.1 and previous versions)?... please help. IO Believe that the problem lies in the Servlet API - Since this same this is present in the Tomcat 5 and JBoss as well,

--------------------------------------------------------------
ServletOutputStream out=null;
try{

    String abc = null;
    res.setContentType("text/html");
    out = res.getOutputStream();
    out.println("<html><body><br>");
    out.println("");
    out.println(abc);
    out.println("</body></html>");
}catch(Exception er11){ }
---------------------------------------------------------------

Hi,

we also have the same problem in our application(s)... I think you have only one way to do this...

After variable "abc" validated, then check for abc value...

if (abc == null) abc = "";

thats all you can do it, this is new change in Weblogic 8.1.

i hope it may help you..

Hi R.K

shouldnt this be , as we need to compare the null string and not the null object

if (abc.equals("null" ) abc = "";
