RE: Tomcat 4.0: Can webapps dir contain links?

[WEST, Peter]

it should work fine if you have your links correct

e.g when you do ls webapps/mydir you shoudl see the contents of mydir
whether its a link or a directory. If the two look differnet then it wont
work.

try 
cd webapps
ln -fsn ~userA/mydirA .

mind you I use Tomcat 3.2.1 so its possible something is different in your
version but t shoudlnt be.

Subject: Tomcat 4.0: Can webapps dir contain links?


Greetings,

I am trying to set up a Tomcat server to be used for some web development 
classes.  I would like to have each student have there own webapp, so that 
in the webapp dir there would be a link to their public_html directory.  In 
Tomcat4B5, it seems as though tomcat will not follow a soft link to the 
students home directory.  If I make a new directory in webapps, it works 
fine, but the link gives me a 403 application not available message.

If anyone has set up a system like this, I would greatly appreciate their
help

RE: BUG in Tomcat 3.2.1???

[WEST, Peter]

sounds like some file versioning cobblers.
Its more likely JBuilder is using information that Tomcat and apache dont
have.

Hi,

I have a servlet with JBuilder 4 Enterprise + Tomcat 3.2.1.

I made a class named HttpServletGeral like this:
public class HttpServletGeral extends HttpServlet {
  ...
}
and other class named ServletPortal:
public class ServletPortal extends HttpServletGeral {
  ...
}

If I run the servlet into JBuilder, all works fine.
If I try to run out of JBuilder, only Apache+Tomcat,
it runs a OLD code for "init" on HttpServletGeral.

If I rename HttpServletGeral to HttpServletGeral2
the NEW code I made works fine.

This is a CRAZY problem. I don't know what's the problem.

thanks...

[WEST, Peter]

thanks Brett that makes some sense. I'll try it out and see.
We're also looking at JSPC which claims to precompile JSPs a directory ata
time into class files and also generate the appropriate web.xml info to use
it.

at this stage we'll try anything.

Subject: Re: Jikes and Tomcat for JSP compilation


I've got Jikes working with Tomcat 3.2.2.  Tomcat 3.2.x does not read the
"web.xml" file that is in "conf" so you need to update your own web
application's "web.xml".  Add the following lines:



jsp


org.apache.jasper.servlet.JspServlet


jspCompilerPlugin

org.apache.jasper.compiler.JikesJavaCompiler


jspCompilerPath

d:\test\CanogaView\Jikes\win32\1.12\bin\jikes.exe


-2147483646



changing d:\test\CanogaView\Jikes\win32\1.12\bin\jikes.exe to the path where
you have jikes installed and also



jsp


*.jsp



Note that you will get a warning from stderr of something like:

2001-06-06 04:06:34 - Ctx( /CanogaView ): Removing duplicate servlet jsp
jsp(org.apache.jasper.servlet.JspServlet/null)
2001-06-06 04:06:34 - Ctx( /CanogaView ): Removing duplicate *.jsp ->
jsp(org.apache.jasper.servlet.JspServlet/null)

This is because Tomcat has a builtin JSP servlet and mapping configuration
and you are overriding this.

any comment?

[WEST, Peter]

Having looked more into the issue of deploying tomcat without JDK I have
discovered the following. (I have read release notes, looked at Tomcat site,
read JSPC scripts, web.xml, server.xml, looked at Faqs, looked at archived
messages etc).

If you include tools.jar (part of JDK) in classpath JSPs will compile, but
we cannot deploy tools.jar since SUN will not tolerate such larks.

If we change web.xml on Tomcat 3.2.1 to say use the Jikes compiler, it does
not read it, 
this may have been fixed in Tomcat 4 or 5 but we do not wish to change to a
new version that is not well tested yet.

If we change the webserver.jar file to hack it to use the Jikes compiler it
would use it, but then we'd be left deploying a non-standard Tomcat jar
which isnt good.

People on this list have not responded which indicates either...

(a) Nobody knows the answer because they don't deploy Tomcat, and just use
the JDK 

(b) Everybody knows but considers it to obvious to say or write down

(c) The list is having its own political factions battle and will shortly
decide that Tomcat  cannot be mentioned unless you have a blue-Peter badge
and joinign the list shall be outlawed everywhere except in Malta.

can anybody point me to a straightforward "how to get Tomcat to compile JSPs

So far I have changed web.xml server.xml (both of which made no difference).
I have also read that it may be necessary to change the source of a line in
webserver.jar I have the details of this but dont exactly believe it is
necessary??

Any pointers? Ideas?

jikes

[WEST, Peter]

hello, 

I'm trying to force Tomcat to use Jikes to recompile its JSPs but it so far
continues to look for the non-existent JDK (since this is being deployed)

So far I have 

(a) changed web.xml to say use the jikes compiler (uncommented a line)
(b) changed server.xml JSP interceptor to include javaCompiler="jikes" as an
attribute
(c) I read that you need to .

uncomment the following line: Line:52? sw.addInitParam("jspCompilerPlugin",
"org.apache.jasper.compiler.JikesJavaCompiler"); in
org.apache.tomcat.context.WebXmlReader.java 


Is this true, that I need to alter the code and rebuild webserver.jar ?
And is that legal to distribute after changing it???

RE: Virtual Host Context Aliasing

 shot in the dark, but have you tried this...
the actual domains shouldnt need doing in tomcat if Apache is forwarding

Subject: Virtual Host Context Aliasing


I would think this would be a common question, but I couldn't find it
documented, nor asked on this list.

Very often domains are served from 2 urls (www.zzz.net & zzz.net) with the
same functionality. When I configure my virtual hosts in Apache's httpd.conf
this is easy:


 ServerName www.zzz.net
 ServerAlias zzz.net
 DocumentRoot /home/httpd/html/zzz
 
  Options None
  Deny from all
 
 JkMount /*.jsp ajp13
 JkMount /servlet/* ajp13


The following properly placed in server.xml creates 2 seperate contexts for
the same set of servlets and JSPs. Functional, but a little wasteful.

  
   
  

  
   
  

Now, I how do I do an alias Context in Tomcat's server.xml so that there is
only one Host/Context with multiple names??

Thank you in advance.

RE: JSP and Tomcat containers

[WEST, Peter]

1. dunno
2. dunno
but remember that JSPs are compiled into servlets and cached so they all end
up as servlets eventually.
 
3. yes change conf/server.xml
There are 3 ports listed. One is for tomcat receiving HTTP requests, one is
for HTTPS requests (SSL) and one is for communicating with a web server like
apache and for shutdown/startup of tomcat. Pick what ports you want.
4. Try http://java.sun.com/products/servlet/2.2/javadoc/index.html
  it has
HttpJspPage, couldnt see base.
5. dunno, I use servlets that put beans in session and JSPs read from them
but I dont need request params in JSPs

Hi!
 
I'm doing an assignment on Java Server Pages, and I have a couple of
questions about the Tomcat webserver:
 
1. Which container (engine) will be running with Tomcat? The JSP container,
the servlet container, or both?
2. I'm only using JSP-documents, but does the JSP container handle the same
stuff that the servlet container handled before 'the era' of JSP?
3. Tomcat listens on port 8080 - can I get it to listen on port 80, and how?
4. Where can I get the API documentation for class HttpJspBase? I've
searched Suns homepage with no luck.
5. How do I (in my JSP page) read data sent with HTTP POST? I can't use
request.getParameter(java.lang.String);
 
Thanks in advance,

RE: server.xml DTD

server.xml does not use a DTD on Tomcat 3.2.1 
I would guess that you could use web.dtd or make a few slight changes to a

server.xml is just a superset of web.xml info.
