Protecting static content

Hi
I want to protect static content in a webapp from
un-authenticated access. Is this possible?

thanks, eb.

Re: Periodically Refresh Application Bean?

[Tom Drake]

Rick:

There is no need to restart Tomcat just update the 
data stored in your bean.

You could provide a jsp or servlet that maps the input
parameter names / values to setter methods in your 
application bean. Then your external process simply 
needs to send a URL GET (or POST) request with 
the new data.

Alternatively, you could write a class that implements 
ServletContextListener and that also implements Runnable. 
This class could start itself in a new thread in the 
contextInitialized() method. The run() method could wake 
up every now and then and go and get the 'updated' data
you need, then update your Application scope bean.
Don't forget to provide the means to stop your thread in 
the contextDestroyed() method.

The 2.3 Servlet spec features really provide elegant
ways of solving many of the problems that required 
container specific hacks in earlier spec versions.

Good Luck

Tom Drake

new to java, apache and tomcat.. but I want to learn!

[Donald Lee]

I have successfully installed Tomcat on a Linux Mandrake box.  All appears 
to be working with the default page up and running.  I am new to this whole 
Tomcat JSP/Servlet thingy and want to get up and running.  I have been on 
the java.sun.com tutorials for the java language and all that, but I want to 
dig into something and see it work on the server.  I am looking for sample 
code to disect and fiddle with.  I find I learn better that way if I can see 
how something was done.  I am currently looking at the examples in the 
default installation but not really finding what I am looking for.  I would 
like to start with something simple but actually usable like a guest book 
program or a message board.  The code doesn't even need to work, just point 
me in the right direction.  I plan to keep going with this in the best way I 
can.
Thanks

Re: TC 4.0.1/SAXParserFactory.newInstance() error

[George Shafik]

I encountered something similar with building Tomcat 3.2.4. It appears that
it used "relative paths" to find jar files. Keep in mind these relative
paths are based on what you have set the following environment variables to
JAKARTA_HOME, JAVA_HOME and ANT_HOME. You will find the CRIMSON.jar and
JAXP.jar created for you when you use Jakart-ant. Copy these files to the
location its looking for them when you do your Tomcat build.

Re: TC 4.0.1/SAXParserFactory.newInstance() error

[Mark]

I thought CLASSPATH isn't used for locating jars in TC 4.0?  In any case, I
do use the startup scripts that come with Tomcat and was already through
step 3 of your suggestions when I originally posted the question (eg. no
jaxp/crimson available in any Tomcat or $JAVA_HOME directories, and The TC
version of xerces.jar in common/lib).  To answer your question, no my app
isn't bundling xerces or crimson.

I'm not sure why this exception is being thrown to begin with...

I have an application that has a bean with application scope.

Tomcat Bug or Feature ?

[Chris Duprat]

Hi,

My question is about webapps classloader. I wonder why 
Jasper can't find classes in the WEB-INF/classes directory? 
Unable to compile jsp ... cannot find import package. 
I think that when a jsp is requested, Jasper has the same 
classLoader of the webapps. Thus Jasper could find the 
classes in the /WEB-INF/classes and in the 
/WEB-INF/lib/*.jar .
I'm using TomCat 4.0.1 and deploy my webapp in a well
formed war archive. When deploying webapp like cocoon,
there is no problem for accessing the app through a browser.
If Tomcat security need adding a context in order to validate
the webapp, cocoon would'nt have work. So defining a context
for my webapps shouldn't be an obligation and I didn't define one.
To conclude, I wonder why Jasper can't compile my jsp ? 
Following the Servlet Specification, my webapp ClassLoader 
contain classpath to WEB-INF/classes/ and WEB-INF/lib/*jar.
Does Jasper have a different one when he try to compile my JSP?
Perhaps TomCat 4.0.1 Bug ... or mislead conception deploying 
a war archive ...

Bye
Chris

Why does getRemoteHost() always return localhost ??? :((

[Rizki Wicaksono]

I used tomcat-3.2.3 and I don't have any problem when accessing
http://mytomcatserver:8080/examples/jsp/snp/snoop.jsp
from any machine. 
This page return that machine IP address and hostname.

Now, I upgrade my server to tomcat-3.3, and I do have a problem when
accessing : 
http://mytomcatserver:8080/examples/jsp/snp/snoop.jsp
from another machine.
snoop.jsp page sometimes (usually the first try) returns the correct
machine IP address and hostname, but most of the time it returns
localhost or 127.0.0.1

Please help me, since i need my client IP address for security reason.

Re: TC 4.0.1/SAXParserFactory.newInstance() error

[Sriram Narayanan]

Hi,

Looks like there's may be another copy of the Jaxp classes somewhere in the 
classpath..Please try the following:

1. Use the startup scripts that come with tomcat 4.0.1. These unset the CLASSPATH 
environment variables and crete custom variables for 
Tomcat's startup.

2.Check to see if you're having any older Xerces or (Crimson+Jaxp) jars files in 
$JAVA_HOME/lib/ext

3. Remove all instances of the files xerces.jar, parser.jar, crimson.jar and jaxp.jar 
from where ever you have placed them in the $CATALINA_HOME  
sub directories.
Having done that, place a copy of xerces.jar in $CATALINA_HOME/common/lib
The xerces.jar file that comes with tomcat 4.0.1 is 1.72 MB in size (1,808,883 
bytes)

4. Just a question, is your app also bundling Xerces/crimson ? Look for the jars in 
the WIB-INF/lib sub-directory.

TC 4.0.1/SAXParserFactory.newInstance() error

[Mark]

I'm attempting to port a working application to Tomcat 4.0.1 and hit a
problem with SAX parsing.  When this line of code is executed

  SAXParserFactory factory = SAXParserFactory.newInstance();

I got a ClassCastException error:

java.lang.ClassCastException: org.apache.crimson.jaxp.SAXParserFactoryImpl
 at javax.xml.parsers.SAXParserFactory.newInstance(SAXParserFactory.java:148)

I looked at the Tomcat archives and tried what the Tomcat documentation
says to do, eg. move xerces.jar into my WEB-INF directory or into the
$CATALINA_HOME/lib directory and move crimson.jar and jaxp.jar out.
Documentation located at
http://jakarta.apache.org/tomcat/tomcat-4.0-doc/class-loader-howto.html#Tomc
at%204%20and%20XML%20Parsers   After doing that however, I get the same
error but from xerces (org.apache.xerces.jaxp.SAXParserFactoryImpl) vs.
crimson.

Has someone slayed this dragon before?  If so, any help would be greatly
appreciated.

Hi All,

I have an Apache server with php and mod_jk. If I use servlets only in one 
virtual host (defined in mod_jk.conf, the only vhost with JkMount directive 
in), Apache will make a connection to Tomcat through mod_jk only for 
connections made to this vhost or it will connect to Tomcat with all it's 
threads?

Tomcat and Orbix 2000

Hi All,

Has any one managed to get Tomcat to work with orbix 2000? If so, help!
Basically, I want a servlet to be an ejb client (running on HP AS 8.0)  and
thus use Orbix.  I can' t get tomcat/my servlet to find the Orbix license
file.

I have tried many things to no avail:
- setting the env variable (IT_LICENSE_FILE) on the system didn't work
- providing the variables as parameters to the servletVM
(-DIT_LICENSE_FILE=...) also didn't work
- setting the env variables in the Code (properties for Initial Context)
didn't work
- placing licenses.txt in WEB-INF/lib, WEB-INF/classes, in Tomcat's
classpath did not work either.

Here is the error I am always getting:

org.omg.CORBA.INITIALIZE: Configuration not found  minor code: 1230242063
completed: No

The meaning for this minor_code/exception_type combination is:
"LICENSE_FILE_NOT_AVAIL"

Any help would greatly appreciated.

Cheers,

Claude
