Netscape Crisis
Please note: I am NOT subscribed to this list, as my ISP does not give me enough space to cope with the level of traffic it generates. Please cc me personally on any reply. Thanks. I have a commercial Java application running under Tomcat [was 3.2.1, now 3.2.2] for the last 4 months. Tomcat has been fantastic, I am extremely happy with it. However I have added extensive help files with lots of graphics and last month had two partial server hangs, which I assumed might be the effect of putting too much regular server load on Tomcat. Therefore I decided to install Apache [on 80] and let Tomcat be delegated the servlet requests [on 8080]. I set this up as follows: 1. include include c:/tomcat/conf/mod_jk.conf-auto to httpd.conf 2. copy mod_jk.dll to c:/program files/apache group/apache/modules 2. uncomment LoadModule jserv_module modules/ApacheModuleJServ.dll at tomcat.conf 3. uncomment ApJServDefaultHost localhost at tomcat.conf 4, add at tomcat.conf DocumentRoot c:/tomcat/webapps/root Directory c:/tomcat/webapps/root Options Indexes FollowSymLinks # Options -Indexes /Directory Location c:/tomcat/webapps/root/WEB-INF/ AllowOverride None deny from all /Location and it runs fine. I tested it and notified the client that I would roll out the new version on Monday. Today I have realised that although it works fine on MS IE, it does not work with Netscape Communicator [versions 4.75 or 6.0]. What happens is that regular pages are served OK but my servlets get displayed as raw HTML. If I modify the URL to access port 8080 instead the page gets displayed correctly, so the problem seems to be related to the Apache/Tomcat handoff. I suspect this is a known problem, but I couldn't see any reference in the FAQ. I wouldn't bother you guys on the mailing list if I hadn't already promised a Monday delivery...

Servlet handling Apache errors
Hi, For days I've been searching the Internet for clues as to how to solve this problem. I'm using Tomcat 3.2.3 connected to Apache 1.3.19 through mod_jk. The situation is as follows: when Apache comes up with a 404 error we're using Apache's ErrorDocument to pass control on to a new program which searches the files availbale to the web server for possible file name matches according to certain criterias. These possible matches are returned as links in the 404 error page. We used to do this by pointing the ErrorDocument 404 to a PHP page. With PHP this is simple, as we can make use of Apache's environment variables to figure out the original request URI. A new customer is interested in the same functionality, but wants us to use servlet instead of PHP. My Apache server, foo.bar, has ErrorDocument 404 /myServlet/errorHandler in its httpd.conf. When a client requests http://foo.bar/foobar.html and foobar.html doesn't exist, a 404 error occurs. Because of the ErrorDocument directive in httpd.conf, Apache invokes the errorHandler servlet. However, no traces of the original request to http://foo.bar/foobar.html is available to the servlet. Servlets run out of Apache's process space and therefore has no access to Apache's environment variables, so we saw this one coming. However, in order to search for likely candidates to be returned with the error page, this information needs to be made available to the servlet in some way or another. Anyone got any clue as to how we may solve this situation? Is it possible to pass some of the environment variables as paramters in the ErrorDocument directive?

white space in JSP - question from a newbie
I ran across a problem while trying to learn how to program with tomcat/jsp.
I was running a simple case statement and got an error stating Statement
not reached.
=
Error: 500
Location: /lucas/switch.jsp
Internal Servlet Error:
org.apache.jasper.JasperException: Unable to compile class for
JSPC:\bin\tomcat\3.2.3\work\localhost_8080%2Flucas\_0002fswitch_0002ejspswit
ch_jsp_3.java:74: Statement not reached.
out.write(\t\r\n\r\n);
^
===
I couldn't figure this out for a while until I understood out how to view
the java produced by the jsp code. Because my case statement had
whitespaces between jsp tags the jasper engine decided to produce out.write
statements in the wrong place.
I modified my jsp to work but I wanted to ask if this was a bug.
I can just format my code differently, but it seems like a error other
newbies would make and I am sure it can get a bit nastier with more
complicated code. Is this behaviour part of the spec or can I expect
different implementations to behave differently.

Here is a listing to reproduce the error. I have fixed most of the
whitespace problem exept for the case statement just before monday.

Re: jdbc odbc bridge on linux
The jdbc odbc bridge requires an odbc driver on the local machine. The local datasource then points to the remote machine that the server is on, rather than the JDBC URL. The jdbc odbc driver is also not multi-threaded, so not a good choice for using with Tomcat. I'm not aware of any free jdbc drivers that will work with SQL Server, but there are a number of commercial solutions. I use the OPTA 2000 driver from www.inetsoftware.de.
