Tomcat error in DFM 3.0.5

Hi,
On a LMS 3.0.1, DFM 3.0.5, I've got a Tomcat error, when I want to see the "Alerts and Activity" (see attachement)
Trying to solve the problem, i've made several try:
1. I purged the dfm database (CSCOpx/bin/dbRestoreOrig.pl dsn=dfmInv dmprefix=INV, CSCOpx/bin/dbRestoreOrig.pl dsn=dfmFh dmprefix=FH,
CSCOpx/bin/dbRestoreOrig.pl dsn=dfmEpm dmprefix=EPM)
2. Import devices from DCR (almost 400 devices). I can see all the devices in "Device Management/Device summary"
3. re-install DFM 3.0.5
and this doesn't solve the problem
I attach the "pdshow", if it can help.
Which log file can help you ?
thanks

I add:
As the post (https://supportforums.cisco.com/message/1328737#1328737), I do this:
"NMSROOT/objects/db/win32/dbsrv9 -f NMSROOT/databases/dfmEpm/dfmEpm.db"
and restore the database by
"NMSROOT/bin/perl NMSROOT/bin/dbRestoreOrig.pl dsn=epm dmprefix=EPM"
in attachement, the new pdshow (the EPMDbEngine is started, but the EPMServer is down)
And still "tomcat error"...
If you have an idea...

DFM Email notifications not working - HTTP status 500 error in DFM 2.0.10

Hi All,
I have recently upgraded...
CiscoWorks Common Services from 3.0.5 – 3.0.6
Campus Manager 4.0.6 – 4.0.10 - 4.0.13
Device Fault Manager 2.0.6 – 2.0.10
Now Email notifications stoped working, it was working fine before.
Even when I was upgrading CM from 4.0.6 to 4.0.10, it worked fine meanwhile. After upgraded it from 4.0.10 to 4.0.13, it stoped working completely.
Before I had same issue and resloved by creating new notification group and subscribed.
Now when I am trying to create new notification group I am getting the below error message

Tomcat error:" It is not available the ServletAction" and jars not found

Hi,
I am deploying an application using Ant from MyEclipse IDE.
When I deploy the application with the Ant, it says to me that the application has successfully deployed. I go to webaapps directory and I can see into that it how the application has been deployed with its WAR.
But when I try to excute the application, Tomcat gives me the following error:
Message: It is not available the Servlet Action
Description: The request resource (It doesn`t available the ServletAction) is not available.
If I go to Apache Tomcat`s stdout log I can see two warnings:
WARN: No appends could be found for logger (org.apache.commons.beanutils.Convertutils)
WARN: Please initialize the log4j system properly
But, If I go to the Java Build path of the application I can verify how I have added the commons.beanutils.jar and log4j.jar .
I don`t know why it doesn´t run and I am stuck.
I would be very grateful somebody could help me to solve this problem.
Regards

The logging doesn't need to be set up properly for the web app to function, usually. The more critical point is the error message from Tomcat about the Servlet Action. Is that the exact error message? I'm just asking because I've never seen a Tomcat error written like that. Could you post the exact message.. Are you using Struts? And where are you seeing the Tomcat error message? Is it appearing in the console or in one of the logs or in the browser?
My guess is you have a jar missing from your classpath but I can't tell from what you've posted.

Tomcat error when posting on netpro

Is there a way to make that tomcat error go away?
(when I post I get an error, then I have to go back to the post and edit it to put in the actual text of the post and it sticks.)
Just like I had to do on this one.

I've seen this happening since years.
Since it never happened to me, I've always thought it is actually related to the client or network connection
Altough, I must agree that nothing in theory should cause a post to appear without an author. Unfortunately it seem the forum software here isn't what you call top notch.

BC4J / Tomcat error is back!?!?

Hi all,
Once I encountered the following problem with BC4J using Tomcat:
Error Message: Only one of the two parameters target or targetParam should be defined.
The solution was changing the enablePooling property to false (in the web.xml). Now, I upgraded Tomcat to 4.1.27 and now the problem is back. Changing the property again does not make any difference. Does anyone know (another) solution for this?
Thanks...Hans

Part of my web.xml which I changed:




































































<servlet>
<servlet-name>jsp</servlet-name>
<servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
<init-param>
<param-name>enablePooling</param-name>

just a guess, there is an error in the way you are setting the property (hence the handleSetProperty method that threw the error.
as you amy be newer, a good way to debug a jsp from tomcat that is giving odd errors on the page is to view the java source code that tomcat generated from your jsp. look in the work directory, and paw around a bit, and you will find a file called upload_005f1_jsp.java. That is the java servlet tomcat made you rjsp into. look in that file, and you'll see on line 56 the exception was either caught or thrown. then look for the property that it tried to set just above it. that is the property that tomcat got mad about. (either a mispelling on your part, or their docs are wrong - altered api perhaps? ) Anyway, if you continue to get frustrated with the orielly classes, look at commons-uploader from jakarta. It is a wonderful file upload library, and I have used it a lot in several struts apps.

I am pretty new at web development, and any clue or pointer would help.

Is that not ok? or something else is wrongYou've installed JDK 6. It doesn't follow that you
don't have JDK 5 installed as well. Clearly you do,
and clearly you're running Tomcat with it (even if
you didn't mean to).I am little bit confused may be due to your strong english language.
1) I compiled with jdk (1.6.0-b105) in OS=xp (at my labtop)
2) I installed jdk-6u1-linux-i586-rpm.bin and jdk-6u1-linux-i586.rpm on my dedicated server
My question is jdk that i installed on my dedicated server is ok if this is right then why its throwing the subject error?? I need solution plz.
Please get me pardon if didn't understand your answer

Tomcat error: "method not found"

I'm starting a new thread because the issue is method not found.
So kindly bear with me.
I'm using Tomcat 5 with Javac 1.4.2. I have created a test class
called hellothere. The idea is to call a method from JSP.
package helloworld;
import java.lang.*;
public class hellothere {
public String sayworld()
String st="hello from hellothere";
return st;
public int returnint()
return 1;
And the jsp looks like:
<%@ page import="helloworld.*" %>
<html>
<head>
<title> hello there </title>
<body>
<%
hellothere h=new hellothere();
String st2=h.sayworld();
out.println(st2);
out.println(h.returnint());
%>
</body>
</html>
The error I get is:
method not found helloworld.hellothere.sayworld()Ljava/lang/String;
blah blah
When I call the returnint after commenting sayworld I get the same error, i.e. method returnint not defined.
Does anyone know what's going on?
Thanks

Make sure that there is only one version of the class
file on your system. Then check spelling and
capitalization of the method names.
You are not trying to run this from an IDE are you?No. I was using Tomcat 5. I don't see this problem with Tomcat 4.
Thanks

Tomcat error - SocketException: Too many open files

I periodically get this error in Tomcats CiscoWorkds Home/MDC/tomcat/logs/stdout.log file. The symptom occurs after logging in and opening any page on the CiscoWorks Web portal ( eg Common Services ). Several applets fail to load, and I'll see the error included in the attached file come up repeatedly after each page refresh.
After quite a bit of research, I found many recommendations to increase the ulimit for files, using the "ulimit -n" command. I've upped it to "unlimited" and thne problem continues to reoccur.
Here's my environment:
LMS 3.2
Solaris 10 (patched up to the April 2011 CPU )
64 bit SPARC processor
Java Runtime Engine 1.5.0_28
Any more ideas? This might be a case where I need to increase a max network connections setting for each of the Tomcat applications. I've never done that, but that's my best guess.

The dmgtd script sets the number of files for casuser processes. Setting the limit outside of dmgtd will not be helpful. Tomcat should not be running out of file descriptors. When the problem happens again, post the output of pfiles for the Tomcat PID (use pdshow to find the PID for Tomcat). There may be a file descriptor leak somewhere.

Apache Tomcat error on common services (Device Update)

Hi,
Kindly check if you have CSCtj20850-0.info at location CSCOpx\setup\patch
Try this workaround too as it look like rme map files got corrupted :-
Navigate to -->
CSCOpx/www/classpath/com/cisco/nm/xms/psu/maps
Backup these two files (rme*.map) at another location and finally delete them from this location. You need to stop the daemon manager to be able to delete this files with the command net stop crmdmgtd.
Now, run the following command two command, rememer they are one line command :-
1>
set NMSROOT=%CWMIBDIR%\..\..\..
2>
%NMSROOT%\lib\jre\bin\java -classpath %NMSROOT%\lib\jre\lib;%NMSROOT%\lib\classpath;%NMSROOT%\objects\log4j\1.1.3\log4j.jar;%NMSROOT%\MDC\tomcat\shared\lib\MICE.jar;%NMSROOT%\MDC\tomcat\shared\lib\NATIVE.jar;%NMSROOT%\MDC\tomcat\shared\lib\jdom.jar;%NMSROOT%\www\classpath;%NMSROOT%\lib\classpath\servlet.jar;%NMSROOT%\MDC\tomcat\webapps\cwhp\WEB-INF\classes com.cisco.nm.xms.psu.packagemgmt.map.CreateMaps %NMSROOT%\www\classpath\com\cisco\nm\xms\psu\pkgs\rme
The above workaround should generate the rme*.map files again and then it should work fine.
Now, start the daemon manager and wait for 20 minutes before logging back to CiscoWorks.
Note :- Its important to backup (rme*.map) before deleting them.
Many Thanks,
Gaganjeet Singh

Tomcat error on start up

Hi,
I setup Tomcat for local development on my pc, and I get this "Syntax error" on startup:
Syntax error
Using CATALINA_BASE: C:\jakarta-tomcat-5.5.9
Using CATALINA_HOME: C:\jakarta-tomcat-5.5.9
Using CATALINA_TMPDIR: C:\jakarta-tomcat-5.5.9\temp
Using JAVA_HOME: C:\j2sdk1.4.2_06
I followed the tutorial here for the setup:
http://www.coreservlets.com/Apache-Tomcat-Tutorial/#Configure-Tomcat
and it ended with several tests to check .jsp's and servlets, and everything appears to work correctly. I do not have a separate Apache server installed. I was just wondering if I should be worried about that error.
Thanks.

Can you bring up the admin tool when you open it in
the browser?
Sorry, I don't know what the admin tool is.
That's a big problem right there.
What do you see in the command shell when you start
Tomcat?
This stuff?

Tomcat error when using data source.

Hello,
I have a problem in that Tomcat does not seem to be recognising my DB Driver. I have tried linking a global data source to my application as well as adding a project specific one with no luck. Here is some of my files:

//A java snippet I am using to access the DB
InitialContext context = new InitialContext();
DataSource dataSource =
(DataSource) context.lookup("java:comp/env/jdbc/DataSourceExample");
Connection conn = null;
Statement stmt = null;
ResultSet rset = null;
try {
conn = dataSource.getConnection();
stmt = conn.createStatement();I also have my DB drivers in the commons/lib file. I know the connect string works fine because I can access the DB from Eclipse when writing standard Java code.
This is a common problem and I have been searching Google for the last 3 hours but nothing I have tried has fixed my problem.
I am using Tomcat 5.5 and J2EE 5. I am creating the links and resources in Tomcat manager.
I don't get any logs or stacktrace, the only error I get is as follows in the returned JSP page:
DataSource Example
Cannot create JDBC driver of class '' for connect URL 'null'What am I doing wrong?
Cheers
EDIT:
Actually there was some output from the shell. Here it is:

Putting the driver into [TOMCAT]/common/lib is sufficient.
The error I think is not related to finding the driver, but actually not retrieving the correct connection string info.
I never had much luck putting this definition info into server.xml
I have had success putting it into a custom context.xml file for a web app as described [url http://tomcat.apache.org/tomcat-5.5-doc/config/context.html]here
in individual files (with a ".xml" extension) in the $CATALINA_HOME/conf/[enginename]/[hostname]/ directory. The name of the file (less the .xml) extension will be used as the context path. Multi-level context paths may be defined using #, e.g. context#path.xml. The default web application may be defined by using a file called ROOT.xml.
eg [TOMCAT]/conf/catalina/localhost/DataSourceExample.xml
Hope this helps,
