I have completed SCJP last 3 yrs back. Can I give SCWCD now?
Hi Aruneesh ad all,
After setting export DISPLAY=164.56.185.61:0.0
Now its giving error that :
Exception in thread "main" java.lang.InternalError: Can't connect to X11 window server using '164.56.185.61:0.0' as the value of the DISPLAY variable.

Can suggest what to do?
Hi all,
I have one problem on my Project.
We were sending PDF files from Unix server to Web server(having CGI code).
Now we want to send PDF file from unix server to same web server having new Java code(Rewrite Java for CGI)
With this new setup PDF file is successfully posted to webserver.Also on webserver also PDF file is received correctly.But after posting file to webserver Unix side Java Program checks getResponse().getStatusCode() this cammand and this time we are getting following error.

Exception in thread "main" java.lang.InternalError: Can't connect to X11 window server using '164.56.185.61:0' as the value of the DISPLAY variable.

First we were thinking may be X11 server is down on Unix side.But still if we try with CGI programming on web server side then its working fine.
We changed only one input file on Unix side.Remaining code is as it is.
Can some one help me on this issue?
Why this error is throwing.
Thanks Dongshan ,Alexandre Cervieri

Hi Priya,

I have done configuring with jakarta-tomcat-5.5.9 and j2sdk1.4.0 but getting error.

Can I use jakarta-tomcat-5.5.9 and j2sdk1.4.0? Or there is any other simple way to do it?

Hi,
I have finished SCJP a day before yesterday.I got 81 %. And now i m looking forward to give SCWCD. Currently I am working on C / Unix. I dont have any work experience of Java/JSP/Servlet and also do not have any idea about jsp and servlets. Is it possible to do SCWCD without having any experience of JSP/Servlet?
I followed Khalid Mughal guide for the scjp. As I covered only SCJP stuff....I don't know about File management,Applet. Does due to lack of knowlegde , is SCWCD possible? Or we need to learn these things and then start for JSP and Servlet.
And I want to know which book should I refer. Which gives me basic knowlegde to understand concepts of JSP and Servlet and also I can do SCWCD Exam with good marks.
Thanks...
