interesting java.lang.NullPointerException error when first viewing an index.jsp page - refresh once and page loads correctly
This may be a rather easy issue but with my limited knowledge of Tomcat - I thought one of you more qualified folks would have a solution. Whenever I visit the initial index.jsp (via index.htm as a workaround) page I get the following server error: java.lang.NullPointerException at org.apache.jsp.index$jsp._jspService(index$jsp.java:75) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:107) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) and so on Clicking F5 or Refresh once loads the page - so you can see it is quite a nuisance - we have implemented Apache 1.3.27 with Tomcat 4.0.6 - I have also posted some lines of the catalina log and error logs for review below: Catalina_Log 2003-01-09 14:48:39 Ajp13Processor[8009][7] process: invoke java.io.IOException: Broken pipe at java.net.SocketOutputStream.socketWrite(Native Method) at java.net.SocketOutputStream.write(SocketOutputStream.java:91) at org.apache.ajp.Ajp13.send(Ajp13.java:525) at org.apache.ajp.RequestHandler.finish(RequestHandler.java:501) at org.apache.ajp.Ajp13.finish(Ajp13.java:395) at org.apache.ajp.tomcat4.Ajp13Response.finishResponse(Ajp13Response.java:196) at org.apache.ajp.tomcat4.Ajp13Processor.process(Ajp13Processor.java:464) at org.apache.ajp.tomcat4.Ajp13Processor.run(Ajp13Processor.java:551) at java.lang.Thread.run(Thread.java:479) Error log 2003-01-09 22:38:16 StandardWrapperValve[jsp]: Servlet.service() for servlet jsp threw exception java.lang.NullPointerException at org.apache.jsp.index$jsp._jspService(index$jsp.java:75) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:107) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) Any ideas on how I can remedy this issue so that the index.jsp page loads on first "hit" would be greatly appreciated.

Paul, You can view the source of the page at http://www.flex-internet.com/source.txt and the full error and stack trace (?) at http://www.flex-internet.com/error.txt Thanks for the help, Brandon Rodak Web Services Computer Marketing Corporation http://www.cmcflex.com & http://www.flex-internet.com -Original Message- From: Paul Yunusov [mailto:[EMAIL PROTECTED]] Sent: Friday, January 10, 2003 2:19 PM To: Tomcat Users List Subject: Re: interesting java.lang.NullPointerException error when first viewing an index.jsp page - refresh once and page loads correctly On Friday 10 January 2003 04:15 pm, Brandon Rodak wrote: > This may be a rather easy issue but with my limited knowledge of Tomcat - I > thought one of you more qualified folks would have a solution. > > Whenever I visit the initial index.jsp (via index.htm as a workaround) page > I get the following server error: > > java.lang.NullPointerException at > org.apache.jsp.index$jsp._jspService(index$jsp.java:75) at > org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:107) at > javax.servlet.http.HttpServlet.service(HttpServlet.java:853) > and so on > > Clicking F5 or Refresh once loads the page - so you can see it is quite a > nuisance - we have implemented Apache 1.3.27 with Tomcat 4.0.6 - I have > also posted some lines of the catalina log and error logs for review below: It might help if you post some snippets from the JSP. The stack trace for the NPE gives you a clue where in the JSP to look for the culprit and what snippet to post.

It's in your Tomcat's work directory hierarchy. Can you post it too? I am almost certain the problem is in that scriptlet at the top of the page but without looking at the generated servlet's line 75, I can't tell which null reference causes the NPE. The elders were right to caution against scriptlets after all.
