Same here.

* set TOMCAT5_SECURITY to “no” in /etc/init.d/tomcat5.5 and /etc/default/tomcat5.5

Hey

ok sorry, but i try all opinions what your say.
i set the TOMCAT5_SECURITY to “no”,
i add the permission “permission java.io.FilePermission “/var/lib/tomcat5.5/webapps/geoserver/WEB-INF/classes/logging.properties”, “read”;” to /policy.d/04.webapps.policy

and restart the tomcat5.5.

i use debian lenny, java-5-jdk, tomcat5.5 and try to start geoserver.
But when i try to start it with the manager follow message comes: “FAIL - Application at context path /geoserver could not be started
”

excuse my bad english.

I also used this tutorial to get to the admin-page but could not deploy war-archives (orbeon forms in my case). Changing from java-6-sun to java-6-openjdk did not bear fruit. Disabling the java security option in tomcat5.5 startup script and restarting tomcat5.5. did the trick. i.e.

Edit /etc/init.d/tomcat5.5 and change TOMCAT5_SECURITY from ‘yes’ to ‘no’

# Use the Java security manager? (yes/no)
TOMCAT5_SECURITY=no

Good Luck!
My System
Debian Lenny 5.0 amd64

I just used this tutorial on the fresh installation of Lenny without problems, the only thing was to add:
grant { permission java.security.AllPermission; };
to “/etc/java-6-sun/security/java.policy”

I have no idea whether it’s the right solution, but it works

But how is it with some mods etc? Isn’t it better to use apache2 + libapache2-mod-jk instead of the built-in web server in Apache Tomcat?

you may need #chmod +x -R tomcat5.5/

Yann, I had the same problem. If you look at the catalina log file you see a logging.properties exception when tomcat is trying to load your app. The fix is described by brndnbg above.

Hi,

I just installed tomcat5.5 on debian server 40r6, with:
aptitude install sun-java5-jre
aptitude install tomcat5.5 tomcat5.5-admin tomcat5.5-webapps

It is then available from http://localhost:8180/, as well as the Tomcat Manager (http://localhost:8180/manager/html). So far, so good.

Then I create a dummy HTML file I want to see when calling http://localhost:8180/foo.html, I have to put it there:
/usr/share/tomcat5.5-webapps/ROOT/foo.html

If I put a WAR file in this directory, it is automatically expanded:
/var/lib/tomcat5.5/webapps/

BUT the problem is that:
1. it does not show up in the “Tomcat Web Application Manager” page
2. it is not reachable by http://localhost:8180/

If I deploy a WAR using the “Tomcat Web Application Manager”, it is then available in /var/lib/tomcat5.5/webapps, but not shown in the Manager page.

What’s the problem?
It seems I have 2 webapps directories, instead of one.

How can I solve that?

Thanks

Ps. tomcat had problems with your tomcat-user.xml file. My /var/lib/tomcat5.5/conf/tomcat-users.xml looks like:

User ad can then login to both the admin and the manager part of tomcat.

Thanks,

Piece of cake with this HowTo

seems like the doubled angle brackets where interpreted as comments or something. You have to insert your webapps name between ““/var/lib/tomcat5.5/webapps/” and “/WEB-INF/classes/logging.properties”

I would like to annotate that althoug this solution works to get your admin-page, you will not be able to deploy war-archives to the server. To be able to do that, you will have to modify the file “/etc/tomcat5.5/policy.d/04webapps.policy” and find the following block:

grant codeBase “file:${catalina.home}/bin/tomcat-juli.jar” {
//some permissions here
[...]

};

then you add the followin line to the other permissions in the block and fill in your webapps name:

permission java.io.FilePermission “/var/lib/tomcat5.5/webapps/<>/WEB-INF/classes/logging.properties”, “read”;

This is a nasty task and took me quite a few hours on “grepping” through logfiles and googling. It should be done automatically by tomcat. Has anyone a better solution? I’m still a novice in this J2EE thing.

Greets.

I followded those instructions and was able to run tomcat admin/manager (great!!!).
But when I deployed my web app, the app failed to start. The only error I can see in catalina.log is:
SEVERE: Error listenerStart

How can I get more details about what causes the failure???

Thanks!
