RE: CPU Binding ?

[Ralph Einfeldt]

That is not a matter of tomcat but of the jvm and the os.

If the jvm uses more than one cpu on this os tomcat will 
do the same.

- What jvm are you using (vendor / version) ?
- Which jvm options do you set ?

CPU Binding ?

[John Hilton - CPX COA]

Good day,
 
Does anyone know how one sets Tomcat 4.0.6 to utilise more than one CPU
in a multiple CPU machine.
 
Tomcat is running on Windows Server 2003 on a 4CPU IBM machine, and all
the utilisation graphs indicate that the tomcat service is only using
one CPU, I have trawled the documentation and cant seem to spot the
config details to do this ?
 
Regards,
John
 

Re: how to use multiple jk2 connectors?

[Adrian Lanning]

Hi Joseph,

I had the same problem a while ago and never solved it. The root cause is
that for whatever reason the Location-JkUriSet combination acts globally to
the httpd.conf file rather than relative to the virtual host.  I wasn't sure
if the problem was with JkUriSet or with apache's Location directive.  It
sounds like it used to work for you with JkMount so the problem must be with
JkUriSet...

>> Side Note <<
List Users,
Am I correct in assuming the problem lies with JkUriSet?  Has anybody gotten
this to work?
>> <<

I had to work around this by explicitly defining mappings in
workers2.properties.  This, of course, blows the whole concept of mass
virtual hosting out of the water since you have to manually add domains to
the workers2 file...

Does jk work correctly in this sense, where mappings are relative to the
virtual host?  If so, i'm switching back...

RE: Multiple Host (no apache or iis)

[Dean Searle]

What port is tomcat listening to? If you have not changed this then it
would be 8080 (I believe) so you would type in a browser
http://www.test1-domain.com:8080 and it should bring up your site. To
keep from having to enter the port every time, change your server.xml to
listen to port 80 instead. 80 is the default http port.

Best regards,

Dean

Hi!
I have tried to search for this but all hits seems to be about getting
tomcat to work together with apache or iis.

I can't figure out why my test1-domain doesn't answer at all. All I gets
is
a 400-error. What bother me the most is that there is nothing in the
catalina.out log that indicats that there are something wrong so I don't
even know where to start look.

I post the -part of my server.xml below.

No error message when welcome page is not present

[Dean Searle]

Hello Group,

I am running Apache 2.0.48 and Tomcat 4.1.30 with mod_jk2 connector
2.0.2 all on windows xp.

The problem I have is this. I have virtual hosts setup to go to their
own folder for their documentroot=/theirfolder. But if I do not have a
valid welcome file there, either an index.(htm,jsp) It takes me to
tomcat manager page. Without restarting anything I can put a valid file
in the folder and site works fine. Where can I shut this off at? I would
like to get an error page, since I have directory listing shut off.
Would it be in web.xml or server.xml?

Thanks in advance,

Dean

Re: JDBC/mySQL problem.

[Kawthar Bt M Sulaiman]

I'd like to setup my connection pooling upfront so at least I can 
concentrate on other areas later on (still need to learn web services
with java).  I'll give it a rest for a day before start working on it.

Thanks,
--Kawthar

>>> [EMAIL PROTECTED] 18/03/2004 02:42:54 PM >>>
Good.

For development and learning this will work fine. But when you get
ready to
deploy your app you will want to get the Connection pool working.
Usually if
the manual connection works then it is a configuration issue and often
a
typo somewhere. Give it a few days and then go through each piece and
confirm all your spelling and capitalization.

If you want to keep working on the pool, repost the applicable parts of
your
current web.xml, server.xml and code.

how to use multiple jk2 connectors?

[Joseph Shraibman]

I have multiple ip based virtual hosts, so in tomcat I configured three 
seperate engines with connectors on different ports, and in the apache 
 I JkMount the worker that I configured in 
worker.properties to connect on a specific port.  This works fine for 
mod_jk, but when I try mod_jk2 it insistes on using the default host of 
the engine that has the connector listening on port 8009.

This is how I configure jk2:

JkUriSet worker ajp13:localhost:8019

Re: JDBC/mySQL problem.

[Kawthar Bt M Sulaiman]

Hi Doug,

I know basic table creation and simple sql statement.. so I was able to
create the database
and create few tables to get tomcat running with mySQL.  I read few
docs (including the
link you gave to get me started).. but other advance stuff, I'll read
as I need them... :)

Anyway, I've done the manual coding to get driver and connection and it
works
I was able to retrieve username from users table.

Thanks,

Re: JDBC/mySQL problem.

[Kawthar Bt M Sulaiman]

Answers to your question:

1. reboot?  Yes, every single time.  I stopped tomcat and restarted it
everytime I make changes.

2. manual connection?  No, I haven't done this.  Let me try and will
let you know.

3.  ping localhost?  Yes, I can ping localhost.

4. firewall?  No, I'm not running firewall.

5.  I'm using Windows2000 OS.

6.  User rights in database?  Not sure.  How can check this?  Still
learning mySQL.

Thanks,
--Kawthar

Kawthar,

As for Steve's concerns:
It is the same one. The short story: Mark Mathews wrote it MySQL liked
it
and adopted it and him. So it went from org.gjt.mm to com.mysql.  Both
names
will work fine but to be up to date use the com.mysql.

As for server.xml having only one is fine, and on TC4 this is common.
If you
move to TC5 then you can have multiple files with each part applying to
only
the app that it is included with. For now don't worry about it.

If your application is running OK as ROOT other than the DBCP problems
then
you are fine. It is that most people set up a new context and don't
mess
with the ROOT at first. But again if the rest of the app runs you're
fine.

Now for fifty questions:
You are rebooting after changes? It has bitten me several times.

Have you done a manual connection?
Class.forName("com.mysql.jdbc.Driver");
connection =
DriverManager.getConnection(
"jdbc:mysql://localhost:3306/ecpa",
"youruser",
"yourpassword");

If the manual connection fails then:
Can you access the database directly and log on using the username and
password that is in the context?

Can you open a prompt and ping localhost? I have seen it fail.
If so use the IP of your machine if you can ping it otherwise you have
other
issues.

Are you running a firewall on the machine?

What OS are you on?

What are the rights for the user in the database, can the user gain
access
from localhost?

Hi,

Thank you for that, and excuse my delay in responding. I tried what 
you suggested, but found the LogManager class did not contain such a 
method. It did have one method to speak of - getLogManager() which 
returns an instance of LogManager, but that also has no shutdown method. 
I found reset():

LogManager.getLogManager().reset();

I am using JDK 1.4.2_03. How might I sort this hassle out please? It seems 
to be happening very infrequently, but is definately a show stopper!

thanks
Hmm...  Take another look at LogManager's source code.  I absolutely, 100% 
guarantee that LogManager.shutdown() exists.  You are using Log4j-1.2.8, 
right?  I know it exists there and I think it has been around for a while 
anyway (but can't be sure).  Anyway, the proof is in the Javadoc

http://logging.apache.org/log4j/docs/api/org/apache/log4j/LogManager.html#shutdown()

Jake



G.

This has to do with Log4j. Make sure you set up a servlet context listener
and do LogManager.shutdown() in the contextDestroyed() method. This will
take care of your troubles.

RE: JDBC problems with MySQL

[Kawthar Bt M Sulaiman]

I've changed the driver to com.mysql.jdbc.Driver.  Which jdbc jar file
is this?
The one that I have is mysql-connector-java-3.0.11-bin.

I only have one server.xml (newbie.. so don't have many apps).
This file is located under $CATALINA_HOME/conf.  Should it be somewhere
else?

Also, what should my docBase be?
I'm using Win2K OS.  My WEB-INF directory is under
$CATALINA_HOME/webapps/ROOT.
That's why I have my docBase as ROOT.

Still the same exception.

Thnx,
--Kawthar

>>> [EMAIL PROTECTED] 18/03/2004 12:29:21 PM >>>
I was able to find it, and it is a little involved.  Basically on my
system
the issue was the context wasn't being read or involked correctly.  I
exchanged the server.xml with the server-minimum.xml and found that
either
placing the context in the Host tag or better yet in 
/usr/local/tomcat/conf/Catalina/localhost/DBTest.xml
Worked.

I went with the separate file, that way all my webapps have separate
files
and I am not cluttering up the server.xml

Once I did this.  I was A-OK.
If you are using MYSQL make sure your class name isn't
Org.gjt.mm.mysql
According to the docs for mysql that is there only for compatibility. 
Use
com.mysql.jdbc.Driver

Also make sure your jdbc jar file is in 
/usr/local/tomcat/common/lib/  or where ever your tomcat resides make
sure
it is in the common/lib sub directory.

Everything is working great for me now 

If that doesn't help let me know.

Steve

Subject: JDBC problems with MySQL


Users

I know there has been a bazillion messages about this.  I
searched the archives and couldn't find anything to solve my extremely
annoying issue.  It has to be something really simple but I just can't
find
it.

 

My System:

Solaris 9

Tomcat 5.0.19

MySQL 4.0.18

Connector J 3.0.11

 

I have the connector J jar in the /usr/local/tomcat/common/lib dir.

I have basically copied the HOW-TO located at.

http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jndi-datasource-examples-how

to.html

 

and my result is this.


Results


Foo Not Connected
Bar -1

 

I have tried everything I can think of.  I verified the database and
the
user/password combo.  Works good.  I even created a simple Java app
that
connects and performs queries, which worked.  That would indicate
everything
is cool with the Connector J.  I have verified that the jdbc/TestDB is
in
the context and it is.  As best I can tell ds (DataSource) is coming
back
not null, but the call to getConnection is failing.  I created a little
more
verbose web app and get the following message.

org.apache.commons.dbcp.SQLNestedException: Cannot create JDBC driver
of
class '' for connect URL 'null', cause: No suitable driver

 

This has to be something simple, because this works fine on my old
machine.
I know I am forgetting some small step that I did the first time and
failed
to do again.  Trust me I have checked the configs about a million
times, and
can't find any differences.   Any help would be appreciated.

 

Sorry to be so vague here, but this is really simple. I don't know what
else
to include for info.

RE: Kumar's JDBC problems with MySQL

[Steve Gums]

I noticed a couple things.  One I want to be corrected if I am wrong but
your docBase should not be root.  Second your driver for MySQL isn't the
org.gjt thing anymore.  Use com.mysql.jdbc.Driver 

I unfortunately have seen this error far too much in the past few days.  It
is not getting into the JNDI resources.  Your context segment needs repair.

Steve I have included my DBTest.xml from
/usr/local/tomcat/conf/Catalina/localhost/  and it works now.


  

  

  

  factory
  org.apache.commons.dbcp.BasicDataSourceFactory




  maxActive

  maxWait

Subject: Re: Kumar's JDBC problems with MySQL

Kumar,

I've been trying to follow the JDBC pb thread as well and still can't
get rid of the
problem.  Here is what I've done.

Using J Connector 3.0, Tomcat 4.1.30 and mySQL 4.0.18.
I put my "mysql-connector-java-3.0.11-bin" under /common/lib.

1.  Start from simple web.xml:
  
DB Connection
jdbc/mySQLDatabase
javax.sql.DataSource
Container
  

2.  server.xml (located at $CATALINA_HOME\conf\server.xml)
 
  

  
   
   factory
  
org.apache.commons.dbcp.BasicDataSourceFactory
   
   
serverName
localhost

   
databaseName
   ecpa
   
   
pathname
conf/tomcat-users.xml


 username


  
 password
   
 
 
removeAbandoned
   true
   
  
  removeAbandonedTimeout
  200
 
   
   logAbandoned
true
   
  
  maxActive
  100
  
 
  driverClassName
  org.gjt.mm.mysql.Driver
  
  
   url
  
jdbc:mysql://localhost:3306/ecpa?autoReconnect=true
  
   

  
 

3.  In my code:
Context ctx = new InitialContext();
if(ctx == null)
{
throw new Exception("\nNo Context Error");
}

DataSource ds = (DataSource)
ctx.lookup("java:comp/env/jdbc/mySQLDatabase");
if (ds == null)
{
System.out.println("\n DataSource is NULL ");
}

Connection conn = ds.getConnection();
if (conn != null)
{
System.out.println("\nGot Connection ");
Statement stmt = conn.createStatement();
ResultSet rst = 
stmt.executeQuery("select username from
users");
if(rst.next())
{
System.out.println("\n username: " +
rst.getString(1));
}

RE: JDBC problems with MySQL

[Steve Gums]

The MySQL database was never the problem.  The problem was the resource
wasn't being loaded into the JNDI.  Problem was the context segement of my
config.

I am new to this list as of today, so I don't know if anyone has already
answered your question. Tomcat will not connect to mysql unless you have
a password and of course rights to the database. Here is an example.

Use these mySQL commands

mysql -u root  (This command gives your root privledges).

CONNECT YourDatabase
GRANT ALL PRIVILEGES ON *.* TO [EMAIL PROTECTED] IDENTIFIED BY
"Yourpassword" WITH GRANT OPTION;

You must have a password for Tomcat to work with mySQL

Note: the above user should be removed once testing is complete!


/* Next, put something like this in your server.xml file: */

  factory 
  org.apache.commons.dbcp.BasicDataSourceFactory

- 
  url 
 
jdbc:mysql://localhost:3306/Classifieds?autoReconnect=true 
  
  
  
/* NOTE THAT Classifieds would be my JNDI datasource  see the servlet
code below*/


IF CONNECTING VIA A SERVLET PUT THIS CODE BEFORE doPost/doGet

public void init(ServletConfig config) throws ServletException{
super.init(config);
  try{
  System.out.println("init() DeleteDBServlet: Start Loading
Database Driver");
  Context env = (Context) new
InitialContext().lookup("java:comp/env");
  pool = (DataSource) env.lookup("jdbc/Classifieds");

  if (pool == null)
throw new ServletException("`jdbc/Classifieds' is an unknown

  }catch (NamingException e) {
throw new ServletException(e);
  }
  }

I know there has been a bazillion messages about this.  I
searched the archives and couldn't find anything to solve my extremely
annoying issue.  It has to be something really simple but I just can't
find it.

 

My System:

Solaris 9

Tomcat 5.0.19

MySQL 4.0.18

Connector J 3.0.11

 

I have the connector J jar in the /usr/local/tomcat/common/lib dir.

I have basically copied the HOW-TO located at.

http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jndi-datasource-examples
-how
to.html

 

and my result is this.

I have tried everything I can think of.  I verified the database and the
user/password combo.  Works good.  I even created a simple Java app that
connects and performs queries, which worked.  That would indicate
everything is cool with the Connector J.  I have verified that the
jdbc/TestDB is in the context and it is.  As best I can tell ds
(DataSource) is coming back not null, but the call to getConnection is
failing.  I created a little more verbose web app and get the following
message.

org.apache.commons.dbcp.SQLNestedException: Cannot create JDBC driver of
class '' for connect URL 'null', cause: No suitable driver

 

This has to be something simple, because this works fine on my old
machine. I know I am forgetting some small step that I did the first
time and failed to do again.  Trust me I have checked the configs about
a million times, and
can't find any differences.   Any help would be appreciated.

 

Sorry to be so vague here, but this is really simple. I don't know what
else to include for info.

Kumar,

First, I started you your own thread. I do this so that others and I can
keep you straight as to who is who and know it is a seperate issue
although
on the same topic.

Please repost your context portion of the xml, the section of code that
accesses the connection pool and if global, the resourse section of the
server.xml. We need to see your code to help give you some direction.

You can also look back at the thread
RE: Problem using JNDI/DBCP to get DataSouce
for some pointers as well.

As far as I am aware the main difference in TC4 and TC5 when seting up
the
DBCP is that in TC5 you can use xml fragments in your app and not have
to
modify your server.xml. List please correct me if I am wrong.

RE: JDBC problems with MySQL

[Steve Gums]

I was able to find it, and it is a little involved.  Basically on my system
the issue was the context wasn't being read or involked correctly.  I
exchanged the server.xml with the server-minimum.xml and found that either
placing the context in the Host tag or better yet in 
/usr/local/tomcat/conf/Catalina/localhost/DBTest.xml
Worked.

I went with the separate file, that way all my webapps have separate files
and I am not cluttering up the server.xml

Once I did this.  I was A-OK.
If you are using MYSQL make sure your class name isn't
Org.gjt.mm.mysql
According to the docs for mysql that is there only for compatibility.  Use
com.mysql.jdbc.Driver

Also make sure your jdbc jar file is in 
/usr/local/tomcat/common/lib/  or where ever your tomcat resides make sure
it is in the common/lib sub directory.

Everything is working great for me now 

If that doesn't help let me know.

Steve

mod_jk3, Tomcat, Apache2 Wildcard problem (Linux)

[Ken Hensel]

Help please,

I have searched far and wide, but found no answer to this question -
although one guy had the same problem and reverted to mod_jk as a
solution.  This is not a solution for me.
I have the following in my workers2.properties file:

[uri:/myapp/]
[uri:/myapp/*.jsp]
[uri:/myapp/dir1/*.jsp]
[uri:/myapp/dir1/dir2]
[uri:/myapp/dir2/*]
Everything works as expected except for the final one.  The wildcard (*)
by itself after a / is not working.  Instead it tries to access the
pathname on DocumentRoot instead of Tomcat (4.1).
Has anyone had this problem?  I used both binaries and also build
Apache2 and jakarta-tomcat-connectors from source with the same problem.
Any help would be appreciated.

Thanks, Ken

Tomcat 5.0.18 doesn't work

[Anand Gondhiya]

Hi All, 
 I  am using Tomcat 5.0.18  and java version "1.4.2_03" on WinXP.
 My tomcat was working fine till now.  I installed JSTL  and now it doesn't work.
 For JSTL installation  I didnt make any changes to class path or path env. 
variables.
 
 before that It was working fine with request taglib  but now if I point to :
http://localhost:8080/index.jsp  it gives following error: 
 
 
  HTTP Status 404 - /index.jsp
   
   type Status report
 
   message /index.jsp
 
   description The requested resource (/index.jsp) is not available.
 
  Note: index.jsp is lying under   D:\Tomcat 5.0\webapps\ROOT
 
   kindly help   thanks in advance

Re: Kumar's JDBC problems with MySQL

[Kawthar Bt M Sulaiman]

Kumar,

I've been trying to follow the JDBC pb thread as well and still can't
get rid of the
problem.  Here is what I've done.

Using J Connector 3.0, Tomcat 4.1.30 and mySQL 4.0.18.
I put my "mysql-connector-java-3.0.11-bin" under /common/lib.

1.  Start from simple web.xml:
  
DB Connection
jdbc/mySQLDatabase
javax.sql.DataSource
Container
  

2.  server.xml (located at $CATALINA_HOME\conf\server.xml)
 
  

  
   
   factory
  
org.apache.commons.dbcp.BasicDataSourceFactory
   
   
serverName
localhost

   
databaseName
   ecpa
   
   
pathname
conf/tomcat-users.xml


 username


  
 password
   
 
 
removeAbandoned
   true

   logAbandoned

  driverClassName
  org.gjt.mm.mysql.Driver
  
  
   url
  
jdbc:mysql://localhost:3306/ecpa?autoReconnect=true
  
   

  
 

3.  In my code:
Context ctx = new InitialContext();
if(ctx == null)
{
throw new Exception("\nNo Context Error");
}

DataSource ds = (DataSource)
ctx.lookup("java:comp/env/jdbc/mySQLDatabase");
if (ds == null)
{
System.out.println("\n DataSource is NULL ");
}

Connection conn = ds.getConnection();
if (conn != null)
{
System.out.println("\nGot Connection ");
Statement stmt = conn.createStatement();
ResultSet rst = 
stmt.executeQuery("select username from
users");
if(rst.next())
{
System.out.println("\n username: " +
rst.getString(1));
}
conn.close();
}

4.  Error message I got from printStackTrace():

RE: JDBC problems with MySQL

[Tom K]

I am new to this list as of today, so I don't know if anyone has already
answered your question. Tomcat will not connect to mysql unless you have
a password and of course rights to the database. Here is an example.

Use these mySQL commands

mysql -u root  (This command gives your root privledges).

CONNECT YourDatabase
GRANT ALL PRIVILEGES ON *.* TO [EMAIL PROTECTED] IDENTIFIED BY
“Yourpassword” WITH GRANT OPTION;

You must have a password for Tomcat to work with mySQL

Note: the above user should be removed once testing is complete!

Users

I know there has been a bazillion messages about this.  I
searched the archives and couldn't find anything to solve my extremely
annoying issue.  It has to be something really simple but I just can't
find it.

 

My System:

Solaris 9

Tomcat 5.0.19

MySQL 4.0.18

Connector J 3.0.11

 

I have the connector J jar in the /usr/local/tomcat/common/lib dir.

I have basically copied the HOW-TO located at.

http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jndi-datasource-examples
-how
to.html

 

and my result is this.


Results


Foo Not Connected
Bar -1

 

I have tried everything I can think of.  I verified the database and the
user/password combo.  Works good.  I even created a simple Java app that
connects and performs queries, which worked.  That would indicate
everything is cool with the Connector J.  I have verified that the
jdbc/TestDB is in the context and it is.  As best I can tell ds
(DataSource) is coming back not null, but the call to getConnection is
failing.  I created a little more verbose web app and get the following
message.

org.apache.commons.dbcp.SQLNestedException: Cannot create JDBC driver of
class '' for connect URL 'null', cause: No suitable driver

 

This has to be something simple, because this works fine on my old
machine. I know I am forgetting some small step that I did the first
time and failed to do again.  Trust me I have checked the configs about
a million times, and
can't find any differences.   Any help would be appreciated.

 

Sorry to be so vague here, but this is really simple. I don't know what
else to include for info.

Kumar,

First, I started you your own thread. I do this so that others and I can
keep you straight as to who is who and know it is a seperate issue
although
on the same topic.

Please repost your context portion of the xml, the section of code that
accesses the connection pool and if global, the resourse section of the
server.xml. We need to see your code to help give you some direction.

You can also look back at the thread
RE: Problem using JNDI/DBCP to get DataSouce
for some pointers as well.

As far as I am aware the main difference in TC4 and TC5 when seting up
the
DBCP is that in TC5 you can use xml fragments in your app and not have
to
modify your server.xml. List please correct me if I am wrong.

Re: A plan to access files outside the context/Tomcat?

[Parsons Technical Services]

Adrian,

Am running in standalone. Currently on 4.1.29 but production will be 5.0.19.

But will keep it in mind. If my app goes public I may need to set up Apache
to do virtual hosting.

Kumar,

I had considered that, but am running on MySQL and wanted to keep the
database as simple as possible(for my own sanity). Might change my mind.
OK, I just did a little reading and this sounds like an idea I can work
with.
So go ahead and send me both if you don't mind. Just in case. I am on Linux.


Thanks for the feed back. Additional comments welcome.

Doug

RE: A plan to access files outside the context/Tomcat?

[Kumar Abhay-CAK203C]

Hi,

I did the same but I stored images in Oracle database in BLOB fields as I was sure of 
the size of the images.
I can give you the snippets of the servlet if u want to use BLOB.
Else I can give you the snippets for uploading files in a folder in Unix Env 
(/context/pics/*)
Cant say which option is best for you ..
Let me know your decision.

I have a need to place and get, image files, to and from a directory outside of the 
context and outside of Tomcat.

My plan is this:

Have an upload page to allow user to select local file on client and upload to server. 
This is the same tactic as the manager is using with war files.

The folder will have rights set to allow read/write by Tomcat user.

This part, I think, will be staight forward. OK so far??

Next to retrieve the image and serve it back to the client is a little more involved.

The plan:

Servlet to accept all request for the /context/pics/* .

Servlet reads file from directory and writes it out to the Servlet output stream.

Am I nuts or is this a feasible plan?

Just need to know if I am going in the right direction and if anyone has any code 
snippets of the servlet writes.

As for the file I/O I have that covered I think.

Any/all comments welcome.

Sounds like a workable solution.  Are you using apache or some other
front-end to Tomcat?  If so then you can use an alias to serve up the images
rather than serve them up manually with your servlet.  I've done it both
ways in content management systems I've made and letting apache do it saves
a class or two...

Actually you might be able to let Tomcat do it for you if you set up a
connector to listen on port 80.  I've never used Tomcat alone so don't have
any experience doing it that way.

I have a question!

If I use Tomcat5 standalone in production, do I still need to configure the mod_jk ? 
The mod_jk has been giving me too much troubles, and it would be
really great if it is not needed in standalone enviroment. Thanks!

Hi,
Tomcat 5 can be used standalone to serve static content including
images, yes. The same is true for tomcat 3 and 4 as well. People are
using tomcat in production without a front-end server to handle static
content, yes. Is there a drop in performance? Probably yes, but it
depends on the static content, the traffic your site gets, the hardware
and software configuration, and a host of other variables: frequently
the drop in performance is better than the additional maintenance and
setup costs of a separate front-end.

Hi,


I have a few questions concerning running Apache 1.3.29 and Tomcat5 in a virtual

googling for a whole day but I still couldn't find an answer... It seems that there is 
no official solution to this problem. If anyone of you have the same experiences and 
have the problems resolved, please share your thougths with us. Thanks!


Another question I want to ask is that there are JK and JK2 connectors, which one 
should I use to connect tomcat5 to Apache1.3.29? The mod_jk.so I used came from 
Tomcat4.0.3, I am not sure whether it is compatible with Tomcat5. The output from 
"catalina.out" log is complaining about the channel sockets, but the channel sockets 
only appears in the JK2 property files, not the JK one. Is it possible that the Apache 
use the wrong JK to talk to Tomcat? 

Any helps will be greately appreciated!

Thanks!

RE: apache 1.3 tomcat 5.0.19

[Randy Harrison]

Galem,

Mod_jk and mod_jk2 are connectors between tomcat and a standard webserver(apache, 
etc.). If you are going to use tomcat as a stanalone sever you don't
need to connect to apache.

Short answer = no.

Shapira,

I have a question!

If I use Tomcat5 standalone in production, do I still need to configure the mod_jk ?  
The mod_jk has been giving me too much troubles, and it would be
really great if it is not needed in standalone enviroment. Thanks!

Galam.

Re: WebappClassLoader: Lifecycle error : CL stopped

[Jerald Powel]

Hi,

Thank you for that, and excuse my delay in responding. I tried what you suggested, 
but found the LogManager class did not contain such a method. It did have one method 
to speak of - getLogManager() which returns an instance of LogManager, but that also 
has no shutdown method. I found reset():

LogManager.getLogManager().reset();

I am using JDK 1.4.2_03. How might I sort this hassle out please? It seems to be 
happening very infrequently, but is definately a show stopper!

thanks

G.


This has to do with Log4j. Make sure you set up a servlet context listener 
and do LogManager.shutdown() in the contextDestroyed() method. This will 
take care of your troubles.

I know there has been a bazillion messages about this.  I searched the 
archives and couldn't find anything to solve my extremely annoying issue.  It has to 
be something really simple but I just can't find it.

 

My System:

Solaris 9

Tomcat 5.0.19

MySQL 4.0.18

Connector J 3.0.11

 

I have the connector J jar in the /usr/local/tomcat/common/lib dir.

I have basically copied the HOW-TO located at.

http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jndi-datasource-examples-how
to.html

 

and my result is this.


Results


Foo Not Connected
Bar -1

 

I have tried everything I can think of.  I verified the database and the user/password 
combo.  Works good.  I even created a simple Java app that connects and performs 
queries, which worked.  That would indicate everything is cool with the Connector J.  
I have verified that the jdbc/TestDB is in the context and it is.  As best I can tell 
ds (DataSource) is coming back not null, but the call to getConnection is failing.  I 
created a little more verbose web app and get the following message.

org.apache.commons.dbcp.SQLNestedException: Cannot create JDBC driver of class '' for 
connect URL 'null', cause: No suitable driver

 

This has to be something simple, because this works fine on my old machine. I know I 
am forgetting some small step that I did the first time and failed to do again.  Trust 
me I have checked the configs about a million times, and
can't find any differences.   Any help would be appreciated.

 

Sorry to be so vague here, but this is really simple. I don't know what else to 
include for info.

Is this the current state of Tomcat 5.0? It requires a public JRE? What is
a public JRE? Will installing one mean that I can't compile JSP's since
it's a JRE and not a JDK?

Thanks.

(Is this a developer list issue or user list?

Tomcat 4.1.12LE Disappears

[Gary Fix]

Hi,
We are running Tomcat 4.1.12LE under Win2000 SP2 within a command window.
We use j2sdk1.4.1_02 for our servlet code.
We also use the isapi_redirect.dll dated 11/8/2002.
About the time we upgraded from version 3 of Tomcat to version 4, we strated having 
problems 
of Tomcat disappearing with no "apparent" error messages.
In the last 8 days, it has disappeared 8 times.
I have searched for a solution with no luck.
The only error messages I could find are in the isapi_redirect.log and some files 
named 
"hs_err_pid1208.log" showing up in the Tomcat \bin folder.

The  isapi_redirect.log error messages look like this:

Tomcat5 service on Windows

[Daryl Stultz]

Hi folks, I know this question has been asked, but I couldn't find an
answer.

I have installed Tomcat 5.0.19 on Windows 2000 / Java 1.4.1. Right "out of
the box" the service fails to run. With service.bat I can install and
remove the service successfully. Starting the service from the services
panel yields:

Could not start the Apache Tomcat service on Local Computer.
Error 1053: The service did not respond to the start or control request in
a
timely fashion

Running startup.bat works fine.

This is the same condition Mark Turansky reports with 5.0.18.

Running net start tomcat5 yields an equally cryptic error which I can't
remember (nor repeat since I reverted to the previous setup).

Clay Hensley suggested a registry edit that worked for him. No such luck
for me.

This 5.0.19 install is an upgrade from 4.0.24. I did not uninstall 4.0.24,
I simply renamed directories. I did a test upgrade on another machine that
is configured the same and it worked fine. The only notably difference
between the machines is that the failing machine is multi processor.

Any hints for exploring the system would be great. Thanks.

Re: apache 1.3 tomcat 5.0.19

[Emerson Cargnin]

my question is: does tomcat 5 have automatic generation of 
mod_jk.conf and if does, is it the same of 3.2.3?

Emerson Cargnin wrote:

Hi all

I'm migrating a tomcat 3.2.3 isntallation to version 5.
When using 3.2.3, I used to use automatic mod_jk.conf-auto generation 
for use by apache. Does version 5 has the same feature? Or do I have 
to configure it by hand?? any how-to?? It's not mentioned in tomcat 5 
docs..

I used mod_jk, is jk2 prefered There's no linux release for it 
and when trying to build as the readme says, the build doesn't work 
at all...

I'm using suse 9 / apache 1.3 and tomcat 5.

RE: JMX conflict in Tomcat 5.0

Ok, I tried with Tomcat 5.0.19 and 4.1.29.  It works fine on 4.1.29 but it
fails on 5.0.19 (and .18) with the following error:

So, it would appear that Tomcat 5's JMX jar is overriding my web-app's JMX
jar.

Can anyone tell me how Tomcat 5 uses JMX?  Is it possible to move Tomcat's
JMX jar into the server/lib directory?  I understand that Tomcat can use JMX
for the management webapp, but is it required, or optional?  Are there any
other reasons to use JMX?  The tomcat installation will be deployed
stand-alone with only my web app and whatever comes standard with Tomcat 5
(i.e. the management web app, etc).

Thanks,

Mark

Perhaps it's worth trying with 5.0.19?

Back to your original question: there's also commons-modeler
(http://jakarta.apache.org/commons/modeler/) to consider.  Tomcat uses
modeler fairly heavily to build its beans, and modeler had an MX4J
dependency last I checked.

RE: tomcat certificate

[Mark Thomas]

This is not correct. Tomcat does support CLIENT-CERT authentication
'out-of-the-box'. When combined with appropriate authorisation constraints in
web.xml you can limit access to specific URLs.

I have this working quite happily.

Help, Page not found!!!!

[Inandjo Taurel]

hi,

i developed an application using tdk 2.1,jdk1.3.1 on a win2k box and it was 
working just fine!
Now that i try to move it to a unix machine with tomcat installed on it, i 
have this error:

Horrible Exception: java.lang.Exception: Screen template '/Home.vm' not 
found
On the unix box, there is not tdk, just tomcat installed and apache!
All i did was to copy my app folder on my win2k box to the webapp folder 
under tomcat on the linux machine!
Since there is no reference to any folder in the application configuration 
files, there was no modification on that side, the only thing was the 
addition of an environment variable (TDK_HOME).

Is there anything that i am missing or any mistake that i made?
This issue has dragging for the past week!
Thanx.

RE: Problem using JNDI/DBCP to get DataSouce

[D'Alessandro, Arthur]

 For future, recommend snipping any real host/username/passwords for
security reasons.

I am not familiar with Informix, however, given a logged in session by
the user you specify, are you able to execute the query, and return 1 or
more records?

I recommend creating  dummy table just for validation with 1 record, 1
field to minimize the overhead.  A validation query is performed before
each connection object is handed out.

Re: Horrible memory leak in tomcat 5.0.19

Hi,
Does the memory leak occur when you run tomcat standalone?
I can't run the production server in standalone, and I can't seem to hit 
my test server hard enough to reproduce the problem clearly.  I'll keep 
trying.

  Can you
point out its source e.g. by running with a profiler?
I don't have a profiler :(

  Was the load
during these 50 minutes exceptionally heavy?

On the heavy side, but not really stressing the server except for this 
memroy leak.  Tomcat 4.1.18 handled loads like this all the time.

BTW How can I view the jk2 status?  I tried both of these:
In httpd.conf:

JkUriSet worker status

in workers2.properties:
[uri:/status/*]
worker=status:status
In my error_log I see:
[Wed Mar 17 14:26:42 2004] [notice] Apache/2.0.48 (Unix) mod_ssl/2.0.48

... and going to the url just produces a 500 error.

Also The faq at http://jakarta.apache.org/tomcat/faq/connectors.html 
says that mod_jk is the preferred connector and that jk2 is not 
production quality.  My understanding was that jk was in maintence mode 
and jk2 is considered the stable connector.  Is the faq right or is it 
just out of date?

RE: apache 1.3 tomcat 5.0.19

[Shapira, Yoav]

Hi,
Tomcat 5 can be used standalone to serve static content including
images, yes.  The same is true for tomcat 3 and 4 as well.  People are
using tomcat in production without a front-end server to handle static
content, yes.  Is there a drop in performance?  Probably yes, but it
depends on the static content, the traffic your site gets, the hardware
and software configuration, and a host of other variables: frequently
the drop in performance is better than the additional maintenance and
setup costs of a separate front-end.

Re: Port-per-webapp?

[Justin Ruthenbeck]

Tony,

Glad to hear you got it working.  The things you did (clear cache, 
restart services, reenter configuration) often solve problems like 
this.  Doesn't provide for a clean explanation of what was wrong, but 
that's a different story.

As for the escape chars, whether they should be escaped really depends on 
who's reading the value.  I've never used the IIS plugin, so I have no 
idea what the behavior is -- an IIS user would have to chime in.

Hi Justin,

Thank you very much for your help, but I finally got it to work!!
I reconfigured registry settings, cleared cache in Tomcat and IE,
restarted all IIS and Tomcat services manually one by one, and
it began working.
I do have one final question though... In the registry setting
tutorials, I see both c:\tomcat\blahblah and c:\\tomcat\\blahblah
should we or should we not use escape character as in the second
entry?
Thanks again!

RE: Horrible memory leak in tomcat 5.0.19

Hi,
Does the memory leak occur when you run tomcat standalone?  Can you
point out its source e.g. by running with a profiler?  Was the load
during these 50 minutes exceptionally heavy?

apache 1.3 tomcat 5.0.19

[Emerson Cargnin]

Hi all

I'm migrating a tomcat 3.2.3 isntallation to version 5.
When using 3.2.3, I used to use automatic mod_jk.conf-auto generation 
for use by apache. Does version 5 has the same feature? Or do I have to 
configure it by hand?? any how-to?? It's not mentioned in tomcat 5 docs..

I used mod_jk, is jk2 prefered There's no linux release for it and 
when trying to build as the readme says, the buildI doesn't work at all...

I'm using suse 9 / apache 1.3 and tomcat 5.

Re: RE: jk2 shared memory

[tomcatuser]

I was of the understanding that tomcat and apache could communicate via shared memory. 
 Is this true?  I am not sure what it means to run "in-process".  Could you further 
explain?

thank you.

Change the debug value on the context. It is currently 0 or no debugging.
Try 9 and see what you get. I think the top limit is 99.

Perhaps it's worth trying with 5.0.19?

Back to your original question: there's also commons-modeler
(http://jakarta.apache.org/commons/modeler/) to consider.  Tomcat uses
modeler fairly heavily to build its beans, and modeler had an MX4J
dependency last I checked.

Of course I am not running on the same server. This would require different

I am setting up multiple servers so I can host JSP apps for people.  And
this setup makes installs quick and fast.

I typically copy all of CATALINA_HOME for each tomcat instance and never use

CATALINA_BASE.

So in other words - I start with one tomcat install. Get it working - then 
copy the whole thing to a new dir. The only difference between those 2
tomcat 
installations is server.xml. Yes - I end up with redundant copies but I 
prefer it that way. But when I want to upgrade or make changes - its much 
easier to keep things running 24x7 since the directories are NOT shared.

I do not keep any webapps inside my tomcat installation. They all live 
somewhere else on my filesystem.

Hello,
The jmx-remote.jar and jmx-remote-tools.jar were in the archive I
downloaded from jakarta.apache.com (Tomcat 5.0.18).  And I don't mean to
imply that Tomcat doesn't work in general, I mean it doesn't work with my

seem to work apart).

jmx-remote.jar and jmx-remote-tools.jar are not part of the tomcat
distribution.  I don't know where you got them nor what their impact is.

The jmx.jar is the Sun JMX 1.2.1 API and reference implementation (RI).

It DOES work properly out of the box.  In addition, it even works
properly with the latest Sun RI.  Older Sun or other implementations, I
don't know.

RE: jk2 shared memory

[Yiannis Mavroukakis]

Do you mean using jk2 with tomcat as an in-process server? 
You need the shared memory anyway, wont work without it.
But the options that most people end up using as a connection scheme are
either via
sockets or using JNI (in-process). JNI AFAIK works only under Windows, so if
you
are on a *IX OS, you should use sockets. Is there a problem with making port
8009 available
through localhost?

I am trying to figure out the jk2 configuration and need some help.

I want to use the shared memory capability of JK2, but am confused by the

require mutual authentication.  Here is my config file:

###  Start workers2.properties ###

When I comment out the "channel.socket:localhost:8009" section, I cannot
connect to my servlets.  Is there another connector that I should be using?
Or do I need to have port 8009 open?

thank you for the help.

jk2 shared memory

[tomcatuser]

I am trying to figure out the jk2 configuration and need some help.

I want to use the shared memory capability of JK2, but am confused by the requirement 
that I must also use a port (8009).  I have apache configured to require mutual 
authentication.  Here is my config file:

###  Start workers2.properties ###
[logger]
level=DEBUG

[config:]
file=${serverRoot}/conf/workers2.properties
debug=0
debugEnv=0

[uriMap:]
info=Maps the requests. Options: debug
debug=0

[shm:]
info=Scoreboard. Required for reconfiguration and status with multiprocess servers
file=${serverRoot}/logs/jk2.shm
size=100
debug=0
disabled=0

[workerEnv:]
info=Global server options
timing=1
debug=0

[channel.socket:localhost:8009]
info=Ajp13 forwarding over socket
debug=0
tomcatId=localhost:8009

[status:]
info=Status worker, displays runtime informations

[uri:/jkstatus/*]
info=Display status information and checks the config file for changes.
group=status:

[uri:/blah/servlet/*]
info=blah context
context=/blah
debug=1

###  End workers2.properties ###


When I comment out the "channel.socket:localhost:8009" section, I cannot connect to my 
servlets.  Is there another connector that I should be using?  Or do I need to have 
port 8009 open?

thank you for the help.

RE: JMX conflict in Tomcat 5.0

[Mark Richards]

We removed jmx-remote-tools.jar, jmx-remote.jar and jmx.jar from
TOMCAT_HOME/common/lib, and replaced these with the implementation of JMX we
have been using on other platforms.

I should mention that if it is not possible to make Tomcat 5 work properly,
downgrading to Tomcat 4.x is a solution we are willing to take, but we'd
rather not.

Thanks,

Mark

Re: Problem using JNDI/DBCP to get DataSouce

[Parsons Technical Services]

Paul,

Replace this:
  if (dataSource == null)
  {
Context initContext = new InitialContext ();
Context envContext = (Context) initContext.lookup
("java:comp/env");
dataSource = (DataSource) envContext.lookup ("jdbc/OscarsDB");
  }

With this:
 if (dataSource == null)
  {
Context initContext = new InitialContext ();
dataSource = (DataSource) initContext.lookup
("java:comp/jdbc/OscarsDB");
  }

This is working fine for me. Just a note that I am running against MySQL,
but at this point in the code it should not matter especially since the
hardwire way works.

Check SRV.11.2 of the Servlet 2.3 specification, 
"/pix_servlet/*.pxhtml" is not a valid wildcard mapping.  
The choices are:
   - starts with / and ends with /*
   - starts with *.
   - contains the single character /
Anything else requires an exact match on the requested URL.

Never shows up anywhere at all, or just doesn't show up in $CATALINA_HOME/logs?  Try 
using an absolute directory path.

Since you have done several changes, please repost your current context

the DB both with conventional JDBC and DBCP. At this point it sounds like a

Some progress but still not working.

1. Using my connection parameters I can open a connection to the database in
the standard JDBC way.

2. I have to moved the DataSource configuration from GlobalNamingResources
to the apps Context area of server.xml. This seems to have allowed the JNDI
look-up to work. I now get a DataSource instance with sensible contents.

3. But when I ask for a connection it throws
"Cannot get a connection, pool exhausted"
   with a nested exception
"Could not create a validated object"

Beginning to think it's not me but the tomcat server. I'm now moved to
4.1.24 to 4.1.30 but no improvement :(

We originally put these jars there but it didn't work; our application was
unable to connect to the MBean server (or listener... forgive me but JMX
isn't my specialty).  When we removed the Tomcat JMX jars and put ours in
place, the app functioned as we expected.

Subject: JMX conflict in Tomcat 5.0

Hello,
I am working on a web-application that was previously deployed
on
Websphere but we would like to deploy it on Tomcat 5.0.  However, our
application uses JMX and it seems that our JMX jars conflict with
Tomcat's
JMX jars.  We found that if we replace Tomcat's JMX jars with our JMX
jars
our application appears to work but I was wondering what the
ramifications
of this are for Tomcat.  We are using the Sun implementation of JMX (I
think
it's version 1.1).

Is there any way to make this work without mangling the Tomcat
installation?
Will Tomcat work properly with our JMX jars? 

Other details:
Our web-app conforms to Servlet 2.2
JDK 1.3.1
Changing our version of JMX to whatever Tomcat uses is not an option at
this
time.

Thanks,

Subject: JMX conflict in Tomcat 5.0

Hello,
I am working on a web-application that was previously deployed
on
Websphere but we would like to deploy it on Tomcat 5.0.  However, our
application uses JMX and it seems that our JMX jars conflict with
Tomcat's
JMX jars.  We found that if we replace Tomcat's JMX jars with our JMX
jars
our application appears to work but I was wondering what the
ramifications
of this are for Tomcat.  We are using the Sun implementation of JMX (I
think
it's version 1.1).

Is there any way to make this work without mangling the Tomcat
installation?
Will Tomcat work properly with our JMX jars? 

Other details:
Our web-app conforms to Servlet 2.2
JDK 1.3.1
Changing our version of JMX to whatever Tomcat uses is not an option at
this
time.

Thanks,

Re: Tomcat Loadbalancing

[Tim Funk]

I typically copy all of CATALINA_HOME for each tomcat instance and never use 
CATALINA_BASE.

So in other words - I start with one tomcat install. Get it working - then 
copy the whole thing to a new dir. The only difference between those 2 tomcat 
installations is server.xml. Yes - I end up with redundant copies but I 
prefer it that way. But when I want to upgrade or make changes - its much 
easier to keep things running 24x7 since the directories are NOT shared.

I do not keep any webapps inside my tomcat installation. They all live 
somewhere else on my filesystem.

Does this look like a JProfiler list? ;)  Use its help,
http://www.ej-technologies.com/products/jprofiler/resources.html, or if
you must use this list add [OFF-TOPIC] to your subject line as I have.
Thanks,

java.lang.IllegalStateException: zip file closed

[Namasivayam, Sudhakar (Cognizant)]

Hi all,
   I deployed my webapp using the war file biult using ant 1.6.  The webapp is 
deployed and works well. But when i stop and atart again through the manager I get the 
exception Zip file closed error.  But removing and installing again works well...  
What could be posssible cause???
I dont  get this error if i unpack the war and deploy.  But tomcat 4.0.4 under linux  
(jdk 1.4)  does not unpack by default but creates a context.   Reload also works well. 
  Is there any way to unpack the war by default   This issue does not arise in 
tomcat 5.0. But i need to use 4.0 :(

Config : tomcat 4.0.4 ,Struts 1.1, jdk1.4


Thanks in advance,
sudhakar

Re: Slightly OT: NoBodyResponse

Hi and thanks for your response!

Shapira, Yoav wrote:
These are private support classes of the Servlet API.  They're still
present, but they're file-private inner classes and thus no in the
JavaDoc (intentionally).
I thought so, that's why I asked.

 The class name you're quoting for them is
wrong, by the way: it's javax.servlet.http.HttpServlet$NoBodyResponse
and javax.servlet.http.HttpServlet$NoBodyOutputStream.
That explains it. As I said, I just quoted them from several newsgroup 
postings I stumbled across.

Your second guess is also wrong, and I wouldn't normally mention this
but it's significant: there's nothing tomcat-specific (or specific to
any server) in the javax.servlet classes.
It would by all means be bad practice and I would never imply that the 
tomcat developers worked that way, but since HttpServletResponse is 
not final, it could hypothetically be extended by a third party inside 
the same package. I just thought I might have accidently discovered a 
"sin of the past" ;-)
Thanks for your clarification.

	Phil

Re: JProfiler... help!

[bort]

I've deployed my application to a Linux box with Apache and Tomcat.  We are
about to have some people test it, and I would like to profile memory use
and garbage collection.

How can I do that with JProfiler?
