Re: How to get heap dump of Tomcat running as windows service.

[Aditi Sinha]

Hi,

Please find the requested details below

1. What is your OS?
*Windows 7,  32-bit OS. I have even tried on Windows 2k8 server but the
same problem.*

2. How much memory the running Tomcat is using? Do you have enough
space on your hard drive, and does it have access rights to write
there?
*Running Tomcat is using around 247MB and JvmMx is set to 512 MB. There is
enough free disk space available.*
**
*Tomcat is running as the logged on user account and therefore should have
access rights.*
*Also, did not login to machine as remote desktop session. I logged in to
the machine directly.

*Any help appreciated.

Thanks & Regards,
Aditi

Fwd: Problems loading external jar in my app !

[joel badia escolà]

Hello everyone, i have a problem with my jsp app for adding external
jars. First of all I have tried the same code and app directory
structure in netbeans ide "built-in" tomcat and works fine, but when i
try to serve my app in my tomcat installation (installed using
aptitude) it seems that it's impossible to locate the external jar.

Only with this code:

<%@page import="weka.classifiers.trees.RandomTree" %>

<%
RandomTree t = new RandomTree();
out.println();
out.println("It works");
%>

I get this error message:

org.apache.jasper.JasperException: Unable to compile class for JSP:

An error occurred at line: 6 in the generated java file
Only a type can be imported. weka.classifiers.trees.RandomTree
resolves to a package

An error occurred at line: 6 in the jsp file:
/DiseaseDiscover/make_diagnosis.jsp
RandomTree cannot be resolved to a type
3: <%@page import="weka.classifiers.trees.RandomTree" %>
4:
5: <%
6: RandomTree t = new RandomTree();
7: out.println();
8: out.println("It works");
9: %>

I tried to put weka.jar in all this directories my-app/WEB-INF/lib/ &
/var/lib/tomcat6/common/ & /var/lib/tomcat6/server/ &
/usr/share/tomcat6/lib/

In all directories I get the same error message.

Greetings,

Joel

So would that then be

Client -> websocket -> IIS ->  is this still done as AJP or websocket

Is jboss tomcat ready to handle websockets ?

Large sites will use a single URL that ends up resolving the images
from some kind of data source. That data source might be a disk (e.g.
you could forward to the DefaultServlet) or a database (relational or
otherwise) where you would write your own servlet to retrieve the data
yourself.

I would use a servlet that gets the image identifier from the request
parameters or "path info" and then continues from there. As Konstantin
points out, using Tomcat's "aliases" feature means that these requests
may have to perform a linear search through all the aliases to find
the requested resource. If you write a custom servlet, it will likely
perform much better than that.

Hope that helps,

Q) ajp connector

[Alex Samad - Yieldbroker]

Hi

I have a design question. I have an application that uses long lived 
connections back to the server so



App -> IIS -> AJP Connector -> Jboss/Tomcat
Or 
App -> Apache -> AJP Connector -> Jboss/Tomcat

So I know that IIS / Apache can handle lots of connections without pairing it 1 
thread to 1 connection.  And JBoss/Tomcat can handle multiple connection per 
thread.

But can the AJP connector handle multiple connections per thread.

My recent problem with IIS + AJP... IIS limited the number of threads that the 
AJP connector could create, to roughly 265 once it was reached when another 
request was made it was blocked... So it looked like a 1 connection 1 thread 
bottle neck.

Is this by design ... is this a IIS thing or would I see the same issue with 
Apache/AJP

With all due respect, I do not think that this is going to work for the poster. 
 You're saying that your workaround was for an issue with the APR connector, 
but the poster is using the NIO connector.  The APR connector does not use NIO 
or the JVM, so I don't think your workaround is relevant.  In fact I tried your 
workaround previously without success.  The problem is that on older versions 
of Windows (pre-vista) and older versions of the JVM, the NIO libraries do not 
support IPv6 (see bug report).

As a side note, the poster could switch from NIO to the APR connector, and it 
would likely resolve his problem (just like he reported switching to the BIO 
connector resolved his problem).  Just assuming that the poster wants to stick 
with the NIO connector.

One workaround is to explicitly define the IPv4 and IPv6 addressing in the 
.
That is, add address="0.0.0.0" for any IPv4 connectors and address="[::]" for 
any IPv6 connectors. (Or use your real addresses instead of the "any" addresses 
listed here.)
This means setting up 2 sets of connectors for each port/protocol, but there's 
nothing wrong with being explicit.
This is what I had to do to get the APR protocol to set up for IPv4.

Plus, why do you have asterisks (*) bracketing the protocols?  All examples 
I've ever seen don't use them.  They are just quoted strings. From the default 
server.xml shipped with Tomcat:

Tried it on my MBP (10.7 w/Java 1.6.0_35) and it worked fine.  Tried on Windows 
XP (only version I have available) w/ Java 1.6.0_35 and was able to replicate 
the problem behavior.  According to the following bug report this is a 
limitation of the OS / JVM.  Looks like a recent versions of Windows and a 
recent version of the JVM are required to resolve this.

Try upgrading from 1.6.0_25 to 1.6.0_35.

 Two HTTP connectors are defined in server.xml.

As I understand it, your ObjectFactory implementation needs to be thread safe.  
See section 4.5 of the link below.

Look at the resource definition...

singleton

"Specify whether this resource definition is for a singleton resource, i.e. one 
where there is only a single instance of the resource. If this attribute is 
true, multiple JNDI lookups for this resource will return the same object. If 
this attribute is false, multiple JNDI lookups for this resource will return 
different objects. This attribute must be true for javax.sql.DataSource 
resources to enable JMX registration of the DataSource. The value of this 
attribute must be true or false. By default, this attribute is true."

>

> How should I close the resource if the webapp is being
> stopped/undeployed?

Again, look at the resource definition...

closeMethod 

Name of the zero-argument method to call on a singleton resource when it is no 
longer required. This is intended to speed up clean-up of resources that would 
otherwise happen as part of garbage collection. This attribute is ignored if 
the singleton attribute is false. If not specificed, no default is defined and 
no close method will be called.

Hi

If you are connected to the Windows machine through remote desktop, 
please try to connect to it using the console session (administrative 
credentials required).
This is because starting with Windows 2003, services run with service 
isolation, but you can get around that by connecting to the console session.
Depending on your operating system version (not the server's version), 
you can connect to the console session by


   After Windows XP SP3, Vista SP1

From the Start menu, choose Run. Type "mstsc /console". Connect
   to the server as usual.

   Other versions

From the Start menu, choose Run. Type "mstsc /admin". Connect
   to the server as usual.

Hope it helps.

Best regards

probably because you have set a large heap size.

because you are probably not setting a heap size.

make some more disk space available, sufficient to permit the heap to be
written to file.

That can't be supported by HTTP - how would the protocol handle sending
more than one HTTP response back to the requestor?

Design an alternative solution that uses a messaging system (perhaps JMS
or AMQP), or in which any member can relay the payload of the request to
other nodes one at a time.

Re: Offline generation of effective web.xml

[Violeta Georgieva]

Thanks for the starting point.
I'm starting to look at the code and when I have the first results I'll
write to the dev list.
Is that OK?

okay.. worked it out.
Seems like I had the application pool set to no .net framework... and

But it seem if you don't set a .net it uses the old IIS6 ISAPI reg settings !
So now I have set .net framework to 4 , even though the  plugin doesn't use it 
(I presume)

  and the thread count is over the 264.

oh yeah.
the pain of using IIS !


Thanks for sharing the solution.

Alex

connection_pool_size is usually for pooling algorithms such as DBCP..
Are you following the DBCP configuration doc?
http://commons.apache.org/dbcp/configuration.html


? so I am looking at the AJP Connector used in IIS on Windows. I
believe this is the relevant page
http://tomcat.apache.org/connectors-doc/reference/workers.html

I believe the connection_pool_size is an indication of how many
(max) worker threads are used to connect from IIS+AJP to tomcat ...


So I am not sure how the BDCP is going to help me, as there is no ODBC
connectivity from my RP's

1. What is your OS?
2. How much memory the running Tomcat is using? Do you have enough
space on your hard drive, and does it have access rights to write
there?

Maybe you could try configuring the service to run as specific user
(instead of Local Service account).

How to get heap dump of Tomcat running as windows service.

[Aditi Sinha]

Hi,



We have web server hosted on Tomcat 7.0.22. Tomcat is running as windows
service.

When we try to get the heap  dump of Tomcat using the following command



*jmap -dump:format=b,file=heap.bin *



we get below error



*: Not enough storage is available to process this command.*



When Tomcat is started manually in console (using command “catalina.bat
start”), we are able to take the heap dump.


Is there any workaround which would allow to take heap dump when Tomcat
running as windows service?


Thanks & Regards,

Aditi
