    IOException in CoyoteReader(Possibly Related to Tomcat Bug #

    Chris Rauschuber Newbie

      Using JBoss 4.0.2(Tomcat 5.5), I'm getting this excpetion from a servlet:
      java.io.IOException
      at org.apache.catalina.connector.InputBuffer.reset(InputBuffer.java:439)
      at org.apache.catalina.connector.CoyoteReader.reset(CoyoteReader.java:121)
      at org.apache.catalina.connector.CoyoteReader.readLine(CoyoteReader.java:178)

      This servlet receives XML over HTTP, so I think it's related to this bug(Getting IOException when line length exceeds 4096):
      http://issues.apache.org/bugzilla/show_bug.cgi?id=24897

      Since the bug is marked as wontfix, what is an appropriate workaround for a servlet that receives an XML document longer than CoyoteReader allows? Putting in line breaks isn't an option since this is being called by our customer.

      Thanks,
      Chris

          Upon further inspection, I don't think that said bug is the cause after all since there aren't any lines in the post that exceed the length limit. I'm going to crank up the log level and see if I can find anything that will help diagnose this.

            I didn't find anything helpful in the log. Is there anything here that should have tipped me off?
