I figured it might be related to the Nio protocol I did, so I changed it to "HTTP/1.1". What a surprise!!
It all comes down after the JSP is invoked, so my perception is that it's related to a bug in the JSP code. Jasper? Any advice would be greatly appreciated, and I'm willing to fix it myself if I can get some advice/guidance as this problem is major for us at the moment. To revert to the old ways will take too long, and we'll loose a lot of time spent in design for current and future changes, which are all based around our moving forward from the JSP templates. java.lang.NullPointerException at org.apache.coyote.http11.InternalOutputBuffer.realWriteBytes(InternalOutputBuffer.java:737) at org.apache.tomcat.util.buf.ByteChunk.flushBuffer(ByteChunk.java:434) at org.apache.tomcat.util.buf.ByteChunk.append(ByteChunk.java:349) at org.apache.coyote.http11.InternalOutputBuffer$OutputStreamOutputBuffer.doWrite(InternalOutputBuffer.java:761) at org.apache.coyote.http11.filters.IdentityOutputFilter.doWrite(IdentityOutputFilter.java:127) at org.apache.coyote.http11.InternalOutputBuffer.doWrite(InternalOutputBuffer.java:570) at org.apache.coyote.Response.doWrite(Response.java:560) at org.apache.catalina.connector.OutputBuffer.realWriteBytes(OutputBuffer.java:353) at org.apache.tomcat.util.buf.ByteChunk.append(ByteChunk.java:325) at org.apache.tomcat.util.buf.IntermediateOutputStream.write(C2BConverter.java:242) at sun.nio.cs.StreamEncoder.writeBytes(StreamEncoder.java:202) at sun.nio.cs.StreamEncoder.implFlushBuffer(StreamEncoder.java:272) at sun.nio.cs.StreamEncoder.implFlush(StreamEncoder.java:276) at sun.nio.cs.StreamEncoder.flush(StreamEncoder.java:122) at java.io.OutputStreamWriter.flush(OutputStreamWriter.java:212) at org.apache.tomcat.util.buf.WriteConvertor.flush(C2BConverter.java:191) at org.apache.tomcat.util.buf.C2BConverter.flushBuffer(C2BConverter.java:134) at org.apache.catalina.connector.OutputBuffer.write(OutputBuffer.java:439) at org.apache.catalina.connector.CoyoteWriter.write(CoyoteWriter.java:143) at org.apache.jasper.runtime.JspWriterImpl.flushBuffer(JspWriterImpl.java:119) at org.apache.jasper.runtime.JspWriterImpl.write(JspWriterImpl.java:326) at org.apache.jasper.runtime.JspWriterImpl.write(JspWriterImpl.java:342) at org.apache.jasper.runtime.JspWriterImpl.print(JspWriterImpl.java:468) at templates.ValuesTag.doEndTag(ValuesTag.java:95) at org.apache.jsp.templates.search_jsp._jspx_meth_tmpl_005fvalues_005f0(search_jsp.java:331) at org.apache.jsp.templates.search_jsp._jspService(search_jsp.java:71) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:70) at javax.servlet.http.HttpServlet.service(HttpServlet.java:803) at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:393) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:320) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:266) at javax.servlet.http.HttpServlet.service(HttpServlet.java:803) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.ApplicationDispatcher.invoke(ApplicationDispatcher.java:654) at org.apache.catalina.core.ApplicationDispatcher.processRequest(ApplicationDispatcher.java:445) at org.apache.catalina.core.ApplicationDispatcher.doForward(ApplicationDispatcher.java:379) at org.apache.catalina.core.ApplicationDispatcher.forward(ApplicationDispatcher.java:292) at templates.JSPTemplate.loadTemplate(JSPTemplate.java:64) at web.Search.replyBody(Search.java:255) at web.Search.doGet(Search.java:73) at javax.servlet.http.HttpServlet.service(HttpServlet.java:690) at javax.servlet.http.HttpServlet.service(HttpServlet.java:803) On Thu, Jul 10, 2008 at 4:23 PM, Quintin Beukes <[EMAIL PROTECTED]> wrote: > Hey, > > Can someone please advise me on this one.
