If you 'have no exposed file system', how do you expect to get files?

Re: RedHat and mod_jk

[Leon Kolchinsky]

Hi,

On RedHat installation of mod_jk is as easy as:

1.
# yum install httpd httpd-devel gcc gcc-c++

2.
Go to http://tomcat.apache.org/download-connectors.cgi and download the
source code (I'm giving an example with 1.2.31 version)
# wget
http://apache.mirror.aussiehq.net.au//tomcat/tomcat-connectors/jk/source/jk-1.2.31/tomcat-connectors-1.2.31-src.tar.gz
3.
# tar -xvzf tomcat-connectors-1.2.31-src.tar.gz

Read docs/webserver_howto/apache.html or native/BUILDING.txt for options.

# cd tomcat-connectors-1.2.31-src/native/
# which apxs
# ./configure --with-apxs=/usr/sbin/apxs --enable-api-compatibility
# make
# make install

You don't need any Java packages for that.

Also my way of installing JAVA on RedHat (Since many Apps support only Sun's
JDK/JRE):

JAVA INSTALLATION:
--
1. Go to http://www.oracle.com/technetwork/java/javase/downloads/index.htmland
download latest Self Extracting Installer.

Put it all under /opt or any other dir. you choose.
[root@vera126 downloads]# ls -l /opt
-rw-r--r--  1 root root  85052342 May 19 11:15 jdk-6u25-linux-i586.bin
[root@vera126 downloads]# cd /opt

# sh jdk-6u25-linux-i586.bin
# ln -s jdk1.6.0_25 jdk

# updatedb;locate javac |grep bin
/opt/jdk1.6.0_25/bin/javac
2.
Here /opt/jdk is the actual JAVA_HOME for your machine. Note this as you
will need it to run the following commands.

alternatives --install /usr/bin/java java /opt/jdk/bin/java 100
alternatives --install /usr/bin/jar jar /opt/jdk/bin/jar 100
alternatives --install /usr/bin/javac javac /opt/jdk/bin/javac 100

3.
Finally you should configure alternative to use Sun's JVM as the default
JVM. To do this type:
# /usr/sbin/alternatives --config java

4.
In the future when we update Java, we only need to update this symlink (for
JAVA_HOME)
/opt/jdk

5.
Last check:
[root@vera126 opt]# java -version
java version "1.6.0_25"
Java(TM) SE Runtime Environment (build 1.6.0_25-b06)
Java HotSpot(TM) Client VM (build 20.0-b11, mixed mode, sharing)


I've already seen members of this list giving good tips on that.

Cheers,
Leon Kolchinsky

Right, but when I roll my own, I can more easily keep multiple versions of a
program--Apache, Tomcat, Java, Firebird RDBMS, etc. and switch between them
if need be. (Life, however, has become easier since someone else here took
over the database stuff. Now I just run whatever version of Firebird
OpenSuSE is installing, and let production worry the final version.)

Re: How can i change JSESSIONIDSSO cookie name?

[Mathan Karthik]

It has been verified, we have to set only 
org.apache.catalina.authenticator.Constants.SSO_SESSION_COOKIE_NAME  in system 
properties. No need to set org.apache.catalina.SSO_SESSION_COOKIE_NAME.


Apache Tomcat Configuration Reference - System Properties document has to be 
modified. It has been reported as a bug. Hope they will make the necessary 
changes in document. Thanks a lot.

Glad it now works. Also, it's good that you've reported how it works. The next 
time someone comes up with this problem, hopefully they'll search the mail list 
archives and get the question answered a lot easier (and faster).

As to what's required, I suggest that you experiment and find out what works. 
Or you could read the documentation, including the API available for download 
as apache-tomcat-version-fulldocs.tar.gz.

I've never changed the JSESSIONID or JSESSIONIDSSO names, since I've never had 
a requirement that could be met by doing so. All I did was read the 
documentation, which is probably a good suggestion.

If you find the documentation difficult to follow write a Wiki entry or propose 
a documentation patch and attach it to a bugzilla enhancement request. I've 
seen both suggested several times on the list.

. . . . just my two cents.

   Hi there,
   I am trying to list files and directories within an war-file i.e
   images/summer2010 images/winter2010. The war-file is deployed on a
   tomcat 7 instance with unpackWARs="false".
   Since I have no exposed filesystem getRealPath will return null. So
   I tried to use getResourceAsStream wich works fine for files but not
   for directories.
   My other idea was to use getResource and URL/URI to get a
   java.io.File via JNDI. But this file is not a file nor a directory.

[JSP] List directory content within a war-file

[Dark Before Dawn]

Hi there,

I am trying to list files and directories within an war-file i.e 
images/summer2010 images/winter2010. The war-file is deployed on a 
tomcat 7 instance with unpackWARs="false".
Since I have no exposed filesystem getRealPath will return null. So I 
tried to use getResourceAsStream wich works fine for files but not for 
directories.
My other idea was to use getResource and URL/URI to get a java.io.File 
via JNDI. But this file is not a file nor a directory.

Cheers
Darky

Code Snippet:
// null if unpackWar = false
String absolute = 
this.getServletConfig().getServletContext().getRealPath("files");

out.write("Files: " + absolute);

// jndi
URL url = 
this.getServletConfig().getServletContext().getResource("files");

out.write("" + url.toURI());

File f = new File("file:" + url.toURI());

// Both null
out.write(" isDir: " + f.isDirectory());
out.write(" isFile: " + f.isFile());

InputStream is = 
this.getServletConfig().getServletContext().getResourceAsStream("files/1.txt");


// NPE if directory
BufferedReader br = new BufferedReader(new InputStreamReader(is));
String line;
out.write("content");
while ((line = br.readLine()) != null) {
// print file content
out.write(line +"");
}
br.close();

Hi Mark

Thanks for the response. 


I have added

org.apache.catalina.SSO_SESSION_COOKIE_NAME in system properties. Gave the same 
cookie name for the both system properties. Now Its working.


Is it mandatory to keep both the entries? Please advice.

A quick look at the docs (and javadocs) seems to indicate that this is not 
possible for 5.0.x. All interesting fields are public static final String. Time 
to upgrade. 
 
For 6.0.28, why did you change both? I was under the impression that you only 
wanted the SSO cookie name changed. 
 
>From the the documentation: 
 
org.apache.catalina.SESSION_COOKIE_NAME 
 
Note that the Servlet specification requires this to be JSESSIONID. You should 
not rely on being able to change this. 
 
How did you set the system property? Did you read this? 
 
http://wiki.apache.org/tomcat/FAQ/Miscellaneous#Q29 
 
 
In particular, it's a good idea to create a setenv.sh file in 
$CATALINA_HOME/bin (or $CATALINA_BASE/bin if you're running several Tomcats 
from a base installation) and add the appropriate setting to CATALINA_OPTS. 
Something like: 
 
#!/bin/bash 
CATALINA_OPTS="-Dorg.apache.catalina.SSO_SESSION_COOKIE_NAME=JNONSTANDARDSSO" 
export CATALINA_OPTS 
 
might work. 
 
 
This is based on my reading of the documentation. I've not tried this. 
 
. . . . just my two cents.

Browser Caching Of Static Files (css/images/js)

I recently implemented that static resources of my web application
