  • tomcat start service NoClassDefFoundError?

    - by mobibob
    I am trying to redeploy my server on a new server with a different DNS and IP address. Therefore, I think my problem is in the configuration to find JAR files. Is there a way to get more detail as to which class is being requested so I can narrow down my problem. Does anyone have any suggested troubleshooting guidance for such problem? BTW - the configuration was working on the original server, and I tried to find all the locations in the files: conf/, worker.properties, server.xml, catalina.policy, web.xml. The jarkarta.log repeats the starting... error initializing ... forever. Very boring, therefore, the problem has to be fundamental. Apparently, the error message is recorded in the log across more than one line and would be this: Error occurred during initialization of VM java/lang/NoClassDefFoundError : java/lang/Object [2012-05-21 18:20:33] [info] Procrun (2.0.4.0) started [2012-05-21 18:20:33] [info] Running Service...

  • How can I configure TomCat Java options in a config file?

    - by Kip
    I'm trying to configure Java options passed into TomCat for a 3rd party application that I'm deploying. The instructions that the app provides are: Open the Tomcat configuration tool from the Windows menu at Start All Programs Apache Tomcat Tomcat Configuration. Click Configure and select the Java tab. At the bottom of the Java Options field, enter the following: -Dexample.license.directory="C:\Program Files\example" Stop and restart the application server. However, I need to do this programmatically, so I'd like to know what config file these options can be set in. Using the GUI is impractical for deploying the app to other developers' environments. (I'm using Tomcat 6.0 if that is relevant...)

  • Tomcat 5.5 - multiple contexts using same path

    - by ctn8iv
    Is it possible to set up multiple contexts using the same path? For example: <Context docBase="/www/websites/site1/java/base" path="/base" reloadable="true"/> <Context docBase="/www/websites/site2/java/base" path="/base" reloadable="true"/> I have two sites that use the same path both running on the same server/IP. The sites use different virtual hosts and different ServerNames, but I have no control over the directory structure of the sites because they are maintained by a client. Until now, they have been content with only allowing one site to run at a time, but this is a major hassle, so I need to know if there's a workaround.

  • Test tomcat for ssl renegotiation vulnerability

    - by Jim
    How can I test if my server is vulnerable for SSL renegotiation? I tried the following (using OpenSSL 0.9.8j-fips 07 Jan 2009: openssl s_client -connect 10.2.10.54:443 I see it connects, it brings the certificate chain, it shows the server certificate, and last: SSL handshake has read 2275 bytes and written 465 bytes --- New, TLSv1/SSLv3, Cipher is DHE-RSA-AES256-SHA Server public key is 1024 bit Secure Renegotiation IS supported Compression: NONE Expansion: NONE SSL-Session: Protocol : TLSv1 Cipher : DHE-RSA-AES256-SHA Session-ID: 50B4839724D2A1E7C515EB056FF4C0E57211B1D35253412053534C4A20202020 Session-ID-ctx: Master-Key: 7BC673D771D05599272E120D66477D44A2AF4CC83490CB3FDDCF62CB3FE67ECD051D6A3E9F143AE7C1BA39D0BF3510D4 Key-Arg : None Start Time: 1354008417 Timeout : 300 (sec) Verify return code: 21 (unable to verify the first certificate) What does Secure Renegotiation IS supported mean? That SSL renegotiation is allowed? Then I did but did not get an exception or get the certificate again: verify error:num=20:unable to get local issuer certificate verify return:1 verify error:num=27:certificate not trusted verify return:1 verify error:num=21:unable to verify the first certificate verify return:1 HTTP/1.1 200 OK Server: Apache-Coyote/1.1 Content-Type: text/html;charset=ISO-8859-1 Content-Length: 174 Date: Tue, 27 Nov 2012 09:13:14 GMT Connection: close So is the server vulnerable to SSL renegotiation or not?

  • Which AMI to to use for Java/Tomcat/MySQL in Amazon EC2?

    - by Justin
    I originally posted this on stackoverflow.com and it was suggested serverfault.com might be a better place to ask this question. So here goes: I'm trying to determine which Amazon Machine Image (AMI) to use as my Virtual Server in Amazon's EC2. For now, I'll need to choose an AMI that complies with the AWS Free Usage Tier. I want to deploy a Java app that I've been developing using Eclipse on Windows XP, Tomcat 7 and MySQL 5.5. I'm aware that I can choose the Basic 32-bit Amazon Linux AMI. Then I'd manually install Tomcat and MySQL (does MySQL get installed on the image or separately on an Elastic Block Store (EBS)?). Here's the rub, I'm a bit of a Linux noob. I can start Tomcat and tail the logs and such on Linux but I'm not familiar with the install process for Tomcat and MySQL on Linux and commands like sudo and chmod. I'm happy to get more hands on with Linux but I'm short on time right now. Are there AMI's that already have Tomcat and MySQL bundled? The Request Instance Wizard shows 805 Community AMI's that are Free Tier Eligible. 51 of the Free Tier Eligible AMI's have "Tomcat" in their name. I'm willing to consider using Elastic Beanstalk but my research thus far hasn't found any discussion of using MySQL with Beanstalk. The discussions all seem to use Amazon's SimpleDB. Any advice is greatly appreciated.

  • Zero downtime deployment (Tomcat), Nginx or HAProxy, behind hardware LB - how to "starve" old server?

    - by alexeypro
    Currently we have the following setup. Hardware Load Balancer (LB) Box A running Tomcat on 8080 (TA) Box B running Tomcat on 8080 (TB) TA and TB are running behind LB. For now it's pretty complicated and manual job to take Box A or Box B out of LB to do the zero downtime deployment. I am thinking to do something like this: Hardware Load Balancer (LB) Box A running Nginx on 8080 (NA) Box A running Tomcat on 8081 (TA1) Box A running Tomcat on 8082 (TA2) Box B running Nginx on 8080 (NB) Box B running Tomcat on 8081 (TB1) Box B running Tomcat on 8082 (TB2) Basically LB will be directing traffic between NA and NB now. On each of Nginx's we'll have TA1, TA2 and TB1, TB2 configured as upstream servers. Once one of the upstreams's healthcheck page is unresponsive (shutdown) the traffic goes to another one (HttpHealthcheckModule module on Nginx). So the deploy process is simple. Say, TA1 is active with version 0.1 of the app. Healthcheck on TA1 is OK. We start TA2 with Healthcheck on it as ERROR. So Nginx is not talking to it. We deploy app version 0.2 to TA2. Make sure it works. Now, we switch the Healthcheck on TA2 to OK, switch Healthcheck to TA1 to ERROR. Nginx will start serving TA2, and will remove TA1 out of rotation. Done! And now same with the other box. While it sounds all cool and nice, how do we "starve" the Nginx? Say we have pending connections, some users on TA1. If we just turn it off, sessions will break (we have cookie-based sessions). Not good. Any way to starve traffic to one of the upstream servers with Nginx? Thanks!

  • Tomcat threads vs Java threads

    - by black666
    When using java threads, one has to take care of the basic problems that come with concurrency through synchronization etc. AFAIK Tomcat also works with threads to handle its workload. Why is it, that I don't have to think about making my code threadsafe when it is running in Tomcat?

  • Unable to use JConsole with Tomcat running as windows service

    - by Kees de Kooter
    I am running tomcat 6.0.18 as a windows service. In the service applet the jvm is configured default, i.e. it is using jvm.dll of the JRE. I am trying to monitor this application with JConsole but cannot connect to it locally. I added the parameter -Dcom.sun.management.jmxremote (which works when starting tomcat with the start.bat script). But the jvm does not seem to pick up the parameter.

  • IntelliJ IDEA "Tomcat manager" application

    - by Jon
    Hello, I'm using IntelliJ IDEA 9.0.2 but I assume this question applies to previous versions as well. In the Run/Debug Configurations dialog there is an option called "Deploy 'Tomcat Manager' application", but I haven't been able to find any documentation for how to use it in the IntelliJ help or online. Has anyone had experience using this, and know what URL I could use to access it once Tomcat is running? Thanks!

  • Java / Tomcat memory leak in RedHat Linux?

    - by black-rocky
    Hi, I've got a Red Hat box with 6G memory running Tomcat and I'm trying to figure out how much memory I have left on the box. Problem is, top & jconsole is showing one figure (around 200M), and system monitor is showing a different figure (around 2G). Does anybody know what the difference is? I'm not sure if there is a memory leak happenning here, but the highest memory consumer is a tomcat process that's taking 2.2G of memory. Screenshots below:

  • Tomcat 403 error after LDAP authentication.

    - by user352636
    I'm currently trying to use an LDAP server to authenticate users who are trying to access our Tomcat setup. I believe I have managed to get the LDAP authentication working in the form of a JNDI realm call from Tomcat, but immediately after the user enters their password Tomcat starts throwing 403 (permission denied) errors for everything except from the root page (ttp://localhost:1337/). I have no idea why this is happening. I am following the example at http://blog.mc-thias.org/?title=tomcat_ldap_authentication&more=1&c=1&tb=1&pb=1 . server.xml (the interesting/changed bits) <Realm className="org.apache.catalina.realm.JNDIRealm" debug="99" connectionURL="ldap://localhost:389" userPattern="uid={0},ou=People,o=test,dc=company,dc=uk" userSubTree="true" roleBase="ou=Roles,o=test,dc=company,dc=uk" roleName="cn" roleSearch="memberUid={1}" /> <Valve className="org.apache.catalina.authenticator.SingleSignOn" /> web.xml (the interesting/changed bits) <security-constraint> <display-name>Security Constraint</display-name> <web-resource-collection> <web-resource-name>Protected Area</web-resource-name> <!-- Define the context-relative URL(s) to be protected --> <url-pattern>/*</url-pattern> <!-- If you list http methods, only those methods are protected --> </web-resource-collection> <auth-constraint> <!-- Anyone with one of the listed roles may access this area --> <role-name>admin</role-name> <role-name>regular</role-name> </auth-constraint> </security-constraint> <!-- Default login configuration uses form-based authentication --> <login-config> <auth-method>BASIC</auth-method> </login-config> <!-- Security roles referenced by this web application --> <security-role> <role-name>admin</role-name> <role-name>regular</role-name> </security-role> I cannot access my LDAP setup at the moment, but I believe it is alright as the login is accepted by the BASIC auth method, it's just tomcat that is rejecting it. The roles should be as defined in web.xml - admin and regular. If there is any other information you require me to provide, please just ask! My thanks in advance to anyone who can help, and my apologies for any major mistakes I have made - yesterday was pretty much the first time I'd ever heard of LDAP =D. EDIT: Fixed the second xml segment. Apologies for the formating-fail.

  • Getting Tomcat user in Java

    - by wolfi
    Hey everybody, is there a way to get the logged in user name (and group) from a Tomcat system. I read something about configuring Tomcat, so it is getting the user information out of a database. But I found now information about getting the name of the user (in my GWT Project), which is logged in. I'm trying to write a little GWT project and would like to publish the user name to the front page. Thx for your help.

  • Tomcat: Cache-Control

    - by Itay
    Jetty has a CacheControl parameter (can be specified webdefault.xml) that determines the caching behavior of clients (by affecting headers sent to clients). Does Tomcat has a similar option? In short, I want to turn off caching of all pages delivered by a tomcat server and/or by a specific webapp?

  • Configuring a Context specific Tomcat Security Realm

    - by Andy Mc
    I am trying to get a context specific security Realm in Tomcat 6.0, but when I start Tomcat I get the following error: 09-Dec-2010 16:12:40 org.apache.catalina.startup.ContextConfig validateSecurityRoles INFO: WARNING: Security role name myrole used in an <auth-constraint> without being defined in a <security-role> I have created the following context.xml file: <Context debug="0" reloadable="true"> <Resource name="MyUserDatabase" type="org.apache.catalina.UserDatabase" description="User database that can be updated and saved" factory="org.apache.catalina.users.MemoryUserDatabaseFactory" pathname="conf/my-users.xml" /> <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="MyUserDatabase"/> </Context> Created a file: my-users.xml which I have placed under WEB-INF/conf which contains the following: <tomcat-users> <role rolename="myrole"/> <user username="test" password="changeit" roles="myrole" /> </tomcat-users> Added the following lines to my web.xml file: <web-app ...> ... <security-constraint> <web-resource-collection> <web-resource-name>Entire Application</web-resource-name> <url-pattern>/*</url-pattern> </web-resource-collection> <auth-constraint> <role-name>myrole</role-name> </auth-constraint> </security-constraint> <login-config> <auth-method>BASIC</auth-method> </login-config> ... </web-app> But seem to get the error wherever I put conf/my-users.xml.

  • Grails exploded under tomcat

    - by xain
    Hi, is there a way to use Grails in "exploded" mode on tomcat in order to make individual changes in a running application (like a gif) without having to regenerate the entire war and upload it ? Something like adding an xml file in tomcat's conf/Catalina/localhost that points to an exploded grails application ? Thanks in advance.
