Tomcat: java.io.IOException: Premature packet header end

[Guoben Li]

Hi,

  I have Apache 1.3.26 and Tomcat 4.0.4 installed/configured on the
same host.  When I tried to access Tomcat's examples/jps/index.html
from Apache my browser popped up: "The page cannot be displayed". 
  I had a look of both logs:

  On Tomcat side logs/apache_log.2002-8-30.txt showed:

2002-08-30 14:33:10 WarpEngine[apache.mycfo.com]: Mapping request

   On Apache side logs/error_log showed:

  Anyone can help?  Many thanks!

Need help: Can't get Tomcat "examples" on Apache using mod_webapp.so

[Guoben Li]

Hi,

  I can't get Tomcat "examples" display on Apache. 
The following is a list of all I did and what I got.

  Please, please help.  Many thanks!

Guoben Li

1. Apache 1.3.26; Tomcat 4.0.4 on the same Solaris host
   http://myserver:8080/examples works well;

2. successfully compiled mod_webapp.so from 
   jakarta-tomcat-connectors-4.0.4-src and copied to libexec/.;

3. in httpd.conf, added:
   __
   LoadModule webapp_module libexec/mod_webapp.so
   AddModule mod_webapp.c

   WebAppConnection conn warp localhost:8008
   WebAppDeploy examples conn /examples/
   WebAppInfo /webapp-info
   ___
   
   bin/apachectl configtest had [warn] "mod_webapp.c is already added" but
   "Syntax OK";

4. in server.xml, the only place changed was 'name=':
   ___
   
   ___

5. started tomcat with bin/startup.sh then restarted apache

   http://myserver/examples "The page cannot be found"

   http://myserver/examples/ "The page cannot be displayed"

   http://myserver/webapp-info/ however displays Host and Connections info:

  Host myserver.domain.com:80 
Application Name "examples"
Root URL Path "/examples/"
Connection "conn"

Connection Name "conn"
Connection parameters "localhost:8008"
Provider "warp"
Configuration Details "Host: localhost Port:8008 Address:127.0.0.1 Socket 
Count: 1 Server ID: -653512835"

RE: where is mod_jk.so?

[Guoben Li]

Don,

  It's in jakarta-tomcat-connectors-4.0.4-src.tar.gz from 
  http://jakarta.apache.org/builds/jakarta-tomcat-4.0/release/v4.0.4/src

  after you tar -xf it the subdirectory is ./jk/native/apache-1.3/

Hello,

I am trying to integrate Apache 1.3.26 with Tomcat 4.0.3 binary on Solaris
5.8.
Any pointers to "good" references on this would be appreciated.
I have found some info, regarding httpd.conf edits etc.  My
biggest problem now is coming up with mod_jk.so, source, binary...
Where do I find this module to add to Apache?

Thanks,

Don

Re: sun/tools/javac/Main?

[Guoben Li]

Pete and Julian,

  I looked into $TOMCAT_HOME/bin/tomcat.sh and saw:

CLASSPATH=${CLASSPATH}:${JAVA_HOME}/lib/tools.jar

  So my problem was that JAVA_HOME was not set
properly before starting Tomcat. The script tomcat.sh
does try to guess what JAVA_HOME is (by `which java`)
but in my case the result was incorrect.

  Thanks again!

Re: sun/tools/javac/Main?

[Guoben Li]

Jules and Peter,

   Thank you both for you quick response!

   I found tools.jar in /usr/j2se/lib on my server.
The remaining question is: how to set CLASSPATH for 
Tomcat?  When I run
http://myserver/examples/jsp/dates/date.jsp it is
Tomcat that tries to compile it and create a servlet
for it, right?

sun/tools/javac/Main?

[Guoben Li]

Hi,

  I have Tomcat 3.2.1 configured with Apache on Sun
Solaris 2.7. A home-made servlet I compiled and put in
$TOMCAT_HOME/webapps/examples/WEB-INF/classes/ runs as
expected.

  When I tried any Tomcat provided JSP example in
http://myserver/examples/jsp/index.html, however, I
got

Internal Servlet Error:

javax.servlet.ServletException: sun/tools/javac/Main
at
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:399)
...

Root cause:

java.lang.NoClassDefFoundError: sun/tools/javac/Main
at
org.apache.jasper.compiler.SunJavaCompiler.compile(SunJavaCompiler.java:128)
...

  Has anybody seen this error and found a solution?
There is no directory "sun" or "tools" on this server.

Thanks in advance.
