losing memory
Hi all, The situation: I have several webapplications running on Tomcat (4.1.27). I work with virtual hosts in server.xml. So everything works fine and fast, that's not the problem. But I see a behavior of the free memory allocation I can't clearify. So what's the problem? when I start (or restart) tomcat I see (I created a stats jsp) a free memory allocation of approx. 900 MB (1024 MB allocated). During days, and weeks this free memory is decreasing. I looked to the free memory (application friday restarted) and after a gc the free memory is 760 MB. The applications still working very good and fast but it seems that each day some free memory is lost??(memory leaking??) But why is tomcat not allocated the memory back after a specific time (like a gc)? Who can explain this behavior? Thanx in advanced.

Re: J2SE 5.0 redirects applets to java.com
Hello Doug, thanks for the speedy reply. I am running TC 5.5. I really do not want to upgrade a lower revision with compat patches. The new Java Logo is not on the desktop. The Java Logo consumes the entire webpage and MSIE window fired up to navigate to an applet. I cannot block using the firewall because there is no URL or IP to reference unless I want to block the target URL or block myself. The redirection does not occur until I click the New Java Logo sunburst image (sorry I was not clear). The URL displayed in the address bar of the browser (MSIE) contains the target applet address I am trying to launch. All-the-while the MSIE browser is displaying the New Java Logo with no mouse options available to look at the source or do anything other than re-navigate or kill the window. I will take a chance with a re-install and see what I can do in the Control Panel with changing options, parameters or whatever. Unless Control Panel options work there is definitely something wrong with the jdk. Thanks, David. Parsons Technical Services wrote .. Which version of Tomcat did you download? If 5.0.x , it will run on 1.4.x jdk. If 5.5.x, it will run on 1.5 (or 5.0) JRE and with the compat patch it will also run on jdk 1.4.x I think the new 1.5 java has an update feature and some other things??? built into it that has it phone home. The applet should still run. I have see the new logo on my desktop and applets run fine. You may try to block the app from getting to the Internet with a firewall. The 1.5 adds a Java setting console to Control Panel. It allows you to turn off updates and make other changes. Doug - Original Message - From: David W.

I have been using Tomcat and some version of jdk for several years. Tomcat is my servlet server of choice mostly on Linux systems when my employers allow such things. I recently downloaded the lastest (yesterday) binary for Windows XP. Seeing that the new Tomcat will only run under the new J2SE 5.0 I downloaded and installed: jdk1.5.0_01 executable. After installation the old familiar Tomcat page came up as usual at: http://localhost:8080. What happened next is for my part inexplicable.

Any applets using: HTTP:// where redirected to: http://java.com with the new Java Logo animated sunburst in the middle of the webpage.

Needless to say I am severely hampered by not being able to run Tomcat because of a wayward jdk. I have sent this problem to java.com contact email but so-far ignored by java.com.

url case sensitive
I am running Windows2003, IIS6, Tomcat 5.0.28 connected through JSPISAPI. The problem is only for Mac IE users when domain name (virtual) is typed in using caps. For example www.mydomain.com works just fine, but www.MyDomain.com is going to a site on the same server that is setup as localhost path=. I have endlessly searched for answers on past posts but couldnt come up with anything. I dont think it has to do with IIS or JSPISAPI connecter because going to MyDomain.com:8080 (Tomcat port) does the same thing. And, again, this is only for Mac IE users. Any browser on Windows has no problems, as well as Mozilla on Linux, Safari on Mac. I Am really lost here, any ideas?

(Charles, I hope you did not measure the time for the first

So to me opening the connection is the major problem. Because the code

The code would be much cleaner, if Charles used the JSTL tag-library:

Ok. You're doing this in a jsp. That means Tomcat is:
1) Compiling your jsp to a servlet class.
2) Building a connection from scratch as opposed to picking up a

3) Running the query.
Of these, the first one is the most expensive operation followed by
two. If you want fast, try doing this with a pooled connection and

Problem configure Datasource on Tomcat 4
Hi, I tried to configure datasource as described in the How-To manual on tomcat 4, but it doesn´t work. I found two ways to define a datasource and work with it: On tomcat 4.1.24: 1. Define context-entry in server.xml for my application with resource entry for datasource. 2. Define resource-ref in web.xml of my application. Not a good way, because i cannot change my datasource via admin-console. I have to edit server.xml file with editor and my server have to be restarted. On tomcat 4.1.31: Define datasource via admin-console and then edit server.xml and generate content-entry with resource-link entry. Its also poor because i also have to restart my server. Is there a way to define datasource via admin-console and generate an entry in my web.xml to get a connect to datasource?

So if you put a class - let's say Global - inside the WEB-INF/classes directory of each of two of your web applications, it will be loaded twice. As a fact, a static variable of the Global class - let's say Global.myVar - will exist twice too! But if you put your Global class into the %TOMCAT_HOME%/shared/classes directory ONLY (important: you must remove all occurences of your Global class from the webapps-classes directories to make this work!), it will be loaded by the shared-classloader. Because of the fact that the shared classloader is the parent classloader of all webapp-classloaders, every web-application can access the classes loaded by the shared classloader. But holding resources in static variables inside the shared/classes directory there is not recommmended! Better add a JNDI-resource to your Tomcat's JNDI-context!

Security Questions
Hello; When creating a realm does the table name have to be 'user'? Realm className=org.apache.catalina.realm.JDBCRealm debug=99 driverName=org.gjt.mm.mysql.Driver connectionURL=jdbc:mysql://localhost/tomcatusers?user=dbUseramp;password=d bUser userTable=tomcatusers userNameCol=user_name userCredCol=user_pass userRoleTable=user_roles roleNameCol=role_name / With this realm I get a 403, but no login prompt. Before I go through with recreating the DB and the users I wanted to be sure this was the problem. Also, the web.xml in my projects WEB-INF contains the following: !-- security -- security-constraint web-resource-collection web-resource-namefw/web-resource-name url-pattern*.do/url-pattern http-methodPOST/http-method http-methodGET/http-method /web-resource-collection auth-constraint role-nameadmin/role-name /auth-constraint login-config auth-methodBASIC/auth-method /login-config /security-constraint Right now I don't want any one to use a servlet that is not authorized first. What I was expecting was a standard login prompt with the basic (just getting a 403 as discribed above). However, once I got BASIC working I wanted to shift to a custom form login: login-config auth-methodFORM/auth-method form-login-page/loginpage.html/form-login-page form-error-page/loginpage.html/form-error-page /login-config Can I do this with the url-pattern of *.do? Or do I need to put an actual directory? The reason I ask is how will Tomcat find the login pages? My last question is about this: user-data-constraint transport-guaranteeCONFIDENTIAL/transport-guarantee /user-data-constraint Is it a good idea to have this? I understand it encrypts all data that is sent to the server. It seems to me that no system should be without. But I wanted to check with someone more experienced first whether there were concerns or limitations I am unaware off.

icon, EJB's and Tomcat?, Login-valves, Realms with Oracle.. and other silly questions
Dear Tomcat users, 1. what exactly should the icon tags inside the web.xml do ? Is it simply a central reference for components within the webapp or does it have more powerful implications. i.e. the small icon will be used as an favicon type icon, whenever a user bookmarks a page from the webapp. 2. If I was want to make an App which levers EJB, what do *you* tomcat-users use as an EJB container normally ? I know there is Orion which is free! 3. to what extent is EJB supported within Tomcat 4 and 5? (i have seen some references to an ejb in the /examples). 4. Does any have a sample of a Tomcat valve which I could use, which causes a servlet to be processed after each time a user successfully logs in. 5. Currently we are using a form based realm, with an oracle database. We create a datasource inside of the server.xml using the commons dbcp package from apache. This works fine with Tomcat. Just for fun, we ported the webapp to an OracleApplication server 10g, where the security system failed. Am i right in thinking that we just need to copy the Oracle DataSourceFactory class inside of the server.xml (the database and hence parameters are the same)?, or could it more complicated ? regards, Ben - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Content-Type removed from the Http Response when file is accessed through Tomcat Connector
Hello All, I am facing a problem with the Content-Type getting removed from the Http Response when accessing a binary file packaged in a WAR file through a Web Server (IIS 5.0 or Apache 2.0). My web.xml has the following mime-type mapping: mime-mapping extensionmsi/extension mime-typeapplication/x-msi/mime-type /mime-mapping I have a .msi file packaged inside a WAR which is deployed on JBoss-Tomcat (Tomcat-4.1.x). When I access this msi file through IE browser the browser reads the contents of the msi and displays in the borwser instead of prompting for saving this file. I have tested accessing this file directly from the port 8080, which works fine. It appears that Tomcat connector which is intercepting the requests to and from the Web Server is somehow removing the Content-Type from the Http Response. I have tested fronting Tomcat with IIS 5.0 as well as Apache 2.0. The problem persists on both configurations. Could anyone please point out what am I doing wrong or whether this is a known issue?

I do not think, jsp compilation is the problem - well, the first

So to me opening the connection is the major problem. Because the code

The code would be much cleaner, if Charles used the JSTL tag-library:

Does CoyoteConnector's connectionLinger option work?
Hi all, I am having problems with the configuration of a Tomcat 4.1.27 server on a Windows XP box. Although I use the following connector configuration in my server.xml file: Connector className='org.apache.coyote.tomcat4.CoyoteConnector' acceptCount='10' connectionLinger='-1' connectionTimeout='5000' debug='0' enableLookups='false' maxProcessors='20' minProcessors='5' port='8080' tcpNoDelay='true' useURIValidationHack='false'/ I am getting lots of TIME_WAIT sockets in my computer. The client app is located in a remote machine, and since I disabled the SO_LINGER option on it, I stopped to get TIME_WAITs in the client side. Setting the connectionLinger attribute to -1 should have made accept sockets to close inmediately without passing by this state (at least, that is the behaviour I am getting in the client side). Is there something wrong in my statements, or I have found a bug? Thanks in advance, Rodrigo Ruiz -- No virus found in this outgoing message. Checked by AVG Anti-Virus.

I don't mean to be contrary, I am just trying to pin this down. The
database and tomcat server are only separated by a 10/100 switch. I am
going to run filemon and watch for access denied messages, then regmon
and watch for similar things. The network is very fast, the db server
is not being used by anyone else. It seems to me that if it were

It still runs slowly. And yes it is multiple refreshes.
I have tried to use connection pooling but have not been
able to get
it working yet. Also the thing that I run into with connection
pooling the inability to use the SQL Statement of select
@@IDENTITY
from table.
With connection pooling, you run the risk of getting the ID for a
record that someone else inserted with the same connection.
If connection pooling is the only option, I can work around that
issue.
But it seems that if PHP, ASP, ASP.NET... Can access the
database just
fine without connection pooling, JSP should be able to as well.
Any thoughts?
Thanks for all your input.

I do not think, jsp compilation is the problem - well, the first
request will last long, but after the jsp is compiled, subsequent
calls will not be remarkable slower than executing pure compiled
servlet code.
(Charles, I hope you did not measure the time for the
first request
only
- which indeed includes compilation time, but for
subsequent calls
too).
So to me opening the connection is the major problem.
Because the code
itself contains html-output, I think using jsp is quite ok.
The code would be much cleaner, if Charles used the JSTL
tag-library:

RE: JTDS help
From: Charles P. Killmer [mailto:[EMAIL PROTECTED] I am going to run filemon and watch for access denied messages, then regmon and watch for similar things. The network is very fast, the db server is not being used by anyone else. It seems to me that if it were environmental, it would affect these other programming languages the same. I checked and the jtds.jar file is in tomcat\common\lib. Any other thoughts while you wait for the results from filemon and regmon? Basically, I suspect a delay being introduced, most likely by some unexpected authentication. Last twice I saw a 2-3 second delay, both were from a SQL Server trying to authenticate and not having a domain controller within easy reach. What user is your Tomcat server running as, what protocol are you using to connect to SQL Server? And if you run osql.exe as that same user on that same machine, what behaviour do you see? Other steps to look for delays: 1. Fire up a SQL Profiler. Watch for activity. How soon after the request for the page is made, does the connection request get made? 2. What's the CPU usage on the Tomcat box? On the SQL box? 3. With a network sniffer, monitor the traffic flow between the two boxes. What's being sent when? I'm aware that I could be barking up entirely the wrong tree here - especially if your Tomcat isn't running as a service and is running as your domain user account - but it just might be worth a check. - Peter - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

To the developers of Tomcat and JK: As I can sense that not one single person is willing to respond to this issue, I can only assume that this tomcat-user community is worthless. Not only have I submitted this issue back 6 months ago, but a similar post was made by the user A jie twice within the last week. If you are too ashamed that your software is not reliable enough to be installed in a production environment, at least have the decency of telling us that. When I have to deal with user session data being sent back to the wrong client, sessions getting lost, and numerous log errors stating that the request/response cannot be fulfilled, I can only come to one conclusion.. Tomcat and the JK/JK2 connector are not reliable. See below and tell me that those messages would not cause problems for the client.

And doesn't it seem strange how the JK2 project has been mysteriously abandoned? Thanks for going off in a seemingly better direction only to jump ship and leave everyone SOL. It makes me think that this whole Tomcat development effort is more of just a hobby and not something to be taken seriously. If anyone is willing to contact me on this issue, I would be more than happy to talk one-on-one. If you want to tell me that this is not the forum for ranting about Tomcat or JK, it should be. If you want to blackball me from this community, go ahead, I'm not getting any help from it as it is. I can only hope that this message reaches the people who supposedly support this software and lights a fire underneath them to improve it or tell us that it just doesn't work.

Seems the reason was the missing Realm-definition in your context.xml. To Question 1) Tomcat offers a separate JNDI-namespace for each web application (so if you have 4 web applications you will have 4 namespaces). These namespaces are configured in the context-elements of the corresponsing web-applications. To define resources, you have to nest a Resource-element in your context-element (which should be in context.xml). A resource that is defined in the namespace of a web application cannot be seen by other web applications (because the namespaces are separated from each other). Sometimes, a resource may be required by more than one web application. To avoid configuring this resource several times - once per context - tomcat offers another namespace that is global and exists only once per tomcat instance. If you define a resource there, you can use it in each web application, that is allowed to use it. So how can you allow a web application to use a global resource? Simply link the global resource into the local JNDI-namespace of the web-application! This can be done by nesting a ResourceLink element in the context element of the web-application that should be allowed to use the resource. When defining a ResourceLink-element, you must specify, which global resource you want to link into the namespace (attribut global), which type the resource is that you want to link (attribut type), and which name it should have in the local namespace (attribut name) - this name can be equal to the global name. So the server.xml and context.xml hierarchy could look like the following (sorry for the text-art - use a fixed width font for best results): +- Server | +- GlobalNamingResources | +- Resource GlobResA | +- Resource GlobResB | +- Service +- Engine +- Realm X +- Host www.A.org | +- Context /A1 (defined in context.xml) | | +- ResourceLink to GlobResA, name: LocResA | | | +- Context /A2 (defined in context.xml) | | +- ResourceLink to GlobResA, name: LocResA | | +- ResourceLink to GlobResB, name: LocResB | | | +- Context /A3 (defined in context.xml) | +- Resource, name LocalResA | +- Host www.B.org +- Context /B1 | +- ResourceLink to GlobResA, name: LocResA | +- Context /B2 +- ResourceLink to GlobResB, name: LocResB Question 2) If you do not want to change server.xml (e.g. because you want to deploy your application to a foreign server and you cannot modify server.xml there), you could define a local JNDI-Resource in the context-element of your web-application instead of the GlobalNamingResource (simply move the resource-definition from GlobalNamingResource into your context-element). If you do this, of course you

Is it possible to setup a custom ServerSocketFactory?
Hi all, I am using Tomcat 4.1.27, on a Windows XP SP2 host. I have tried to implement a custom ServerSocketFactory, and configured my CoyoteConnector to use it as its factory in the server.xml file. But, although an instance is created on startup, it seems no call is made to any of its createSocket() methods. Is there anything special that must be done for the connector to use my factory? It seems that CoyoteConnector is creating the ServerSocket by itself, or at least, without asking the specified factory.

javaURLContextFactory class or jar file
Where can I find the org.apache.naming.java.javaURLContextFactory class file or jar file that contains it? I'm trying to set up a simple JUnit test case JDNI fixture to create the JDNI context for my test cases. But I can't find where the class file sits. Does anybody have any idea? I would have guessed it's in the bootstrap.jar file, but when I include that in my classpath, I still get: javax.naming.NoInitialContextException: Cannot instantiate class: org.apache.naming.java.javaURLContextFactory [Root exception is java.lang.ClassNotFoundException: org.apache.naming.java.javaURLContextFactory] Where does Tomcat get it from if not the bootstrap.jar file? Thanks in advance. Dave
Re: outOfMemory exception under high load
Just a thought, I was having the same problem using JNDI for database connection. Our database pool was going crazy due to a lot of connections left unterminated and database memory usage was enormous. Restarting Tomcat would only help for a day or two and than OutOfMemory errors would come up again. Restarting the database, gave us several weeks until the error started coming up again once the memory used by database grew. Thinking that it had something to do with the memory it took to maintain the pool.

Re: [OT] RE: Attn developers of Tomcat and JK
Eric, I do not use jk at this time so am not able to help you directly. If you do some surfing of the archives you will find there are typically three types of users. Total novice who are just looking for a free environment to learn in. Serious user who uses the product for every day life. Cheap user who uses the product because it is free. Often the novice will say just that. I about as dumb as a box of rocks when it comes to Tomcat. These users will often get some sympathy from the community because we have all been there once. The serious user will often ask a question and still dig into the code themselves. On many occasion have I seen a user solve their own problem. Then the cheap user who uses the product because it is free and yet treats it as if they paid thousands of dollars for it. I am not trying to lay blame or label you, but let me ask a question. Have you looked at the source code for jk, jk2 or Tomcat? For this is the power and advantage of open source. If you own a M$ product and have an issue if they do not want to fix it you are stuck with no recourse. Usually you can't even convice them that it is a bug in the code. And this applies to others as well, I had an HP printer that had a problem, the same problem as hundreds if not thousands of other had. HP said it was everything but the printer (which is now scrapped). Yet another printer works fine in it's place. They effectivly sweep it under the rug, yet if it was open source, I bet someone would have found the bug and fixed it. If you will post your config files for jk and server.xml you might also get some feedback. Often a miscofiguration can cause all kinds of grief. One thing that peaks my curiosity is the line that says: Tomcat is probably not started or is listening on the wrong host/port (127.0.0.1:8009). How do you have the listener setup in Tomcat and what IP/name are you using in the config. Seems like sometimes jk is trying to call Tomcat on a port that is not setup to listen for it. So if you are not too disgusted to try again, please repost as stated above. Otherwise good luck on your quest for a different server.

Tomcat 5.0.28 Deploy apps in a /dir/appname like Context
What does work: deploying app in a /appname Context
- I defined a host myhost with a /hostappbase dir as
appBase
- I took the sample HelloWorld app, renamed myapp and
wanted it as http://myhost/myapp
- I added a META-INF/context.xml file
- I compiled it with ant all using a build.xml like
the one from
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/appdev/build.xml.txt
- Then compiled and validated the jsp with ant -f
deploy.xml compile where deploy.xml is like build.xml
example from tomcat-deployer-5.0.28
- I also modified the jar destfile tojar
destfile=/hostappbase /${webapp}.war so after
compile, Tomcat automagically detects the new .war and
unpacks it and loads the new application
= Navigation, reloading and even restarting the new
app OK
- I tried ant -f deploy.xml deploy
= Tomcat manager undeploy and again redeploy the
application, everithing OK.
What does NOT work: deploying similar app in a
/dir/appname Context
- I want a copy of HelloWorld, copied all as myapp2
and edited build.xml deploy.xml context.xml and
web.xml
- THE DIFFERENCE is that now I want it as
http://myhost/SOMEDIR/myapp2
- So I mkdir /hostappbase/SOMEDIR
- Changed the files that way:
--- build.xml ---
property name=app.name value=myapp/
property name=app.path
value=/${app.name}/
---
property name=app.name value=myapp2/
property name=app.path
value=/SOMEDIR/${app.name}/
property name=build.home
value=../myapp/
---
property name=build.home
value=../myapp2/
--- deploy.xml ---
property name=webapp value=myapp/
property name=path value=/myapp/
---
property name=webapp value=myapp2/
property name=path
value=/SOMEDIR/myapp2/
jar destfile=/hostappbase/${webapp}.war
---
jar
destfile=/hostappbase/SOMEDIR/${webapp}.war
path=${path}
war=/hostappbase/${webapp}.war update=true /
---
path=${path}
war=/hostappbase/SOMEDIR/${webapp}.war update=true
/
--- context.xml ---
workDir=work/Catalina/myhost/myapp
path=/myapp
---
workDir=work/Catalina/myhost/SOMEDIR_myapp2
path=/SOMEDIR/myapp2
docBase=/hostappbase/myapp
---
docBase=/hostappbase/SOMEDIR/myapp2
--- web.xml ---
(no changes)
I followed the same steps and the result was:
1- when executed ant -f deploy.xml compile Tomcat
does not realize there is a new .war and does not load
nor unpacks the new app.
2- when executed ant -f deploy.xml deploy it seems
to load the app, but I got this error from Tomcat (so
ant says BUILD FAILED):
StandardContext[/manager]Manager:
ManagerServlet.install[/SOMEDIR/myapp2]
java.net.MalformedURLException: no !/ in spec
I found this note:
http://java.sun.com/j2se/1.4.2/docs/api/java/net/JarURLConnection.html
So I tried this change in deploy.xml:
war=jar:file:/hostappbase/SOMEDIR/${webapp}.war!/
And I got a FileNotFound error from ant.
I tried combinations but none of them worked.
What is my mistake?
Thanks in advance.

Subject: Re: HTTPconnector problem
As I understand the documentation (and my past experience
shows) you are not correct. :)
But we don't actually run the documentation. Here's the code of interest (from
5.0.25, the last one I downloaded the source for):
if (! req.scheme().isNull()) {
// use processor specified scheme to determine secure state
request.setSecure(req.scheme().equals(https));
} else {
// use connector scheme and secure configuration, (defaults to
// http and false respectively)
req.scheme().setString(connector.getScheme());
request.setSecure(connector.getSecure());
}
If I'm reading this correctly, the connector's secure attribute will only be
used if the scheme for the request has not been set. I suspect that, in your
case, the scheme is http, forcing the secure attribute for the request to
false.

I have been reading all the online documentation I can dig up and cannot find the solution to my problem. Quite simply, all I want to do is be able to run perl cgi script through my Tomcat server. I uncommented everything having to do with CGI in the Tomcat web.xml conf file, restarted the server and placed my scriptmin the right place. All that happens now is the script is printed up to the screenjust like a txt file. It is executable. I checked the logs and the log says that a 304 code is sent to the browser. ANY help would be much appreciated. Thanks very much. --Alex Alex Brelsfoard Web Applications Developer Web Development Office Worcester Polytechnic Institute 508-831-6147 [EMAIL PROTECTED]
using shared objects from tomcat
Hi (again)! I still have problems useing a shared library from within a tomcat webapp. The same code works from a standalone appication but not from tomcat. If anyone can answer one or more of the following questions I would be happy. 1) Is there any way to log what a .so-file attempts to do without altering the source? This so that I can see if the .so tries anything funny thats not allowed from within tomcat. 2) Is there any way to get more information from an UnsatisfiedLinkError. Now that error is all I get, no reason or root cause at all. 3) What differs in how tomcat and a standalone java application loads libraries? And what is the restrictions on loading subsekvent libraris (ie the first one loads the ones it depends on). If I could assigne Duke Dollars, Expert Exchange Dollars or some kind of Tomcat Dollars I would. -- Andreas Andersson IT Dept.

I use apache to enable cgi scripts, and I had the same problem as you. So, since I don't know Tomcat so well, I can offer you this. Check in your config file to make sure that you have the line(s): AddType application/x-httpd-cgi .cgi .sh .pl AddHandler cgi-script .cgi .sh .pl (I am not actually using this line but maybe you need to) Also, in my httpd.conf file I am using some directives and options such as: Directory /home/nrccwdt/public_html/ Options +Includes +ExecCGI XbitHack On /Directory I am sure you know how the Directory directive works, but make sure that you do have the Options +ExecCGI, and XbitHack On lines also.

RE: Session Objects
It's not impossible to make this work over a cluster but not with the included clustering classes in tomcat. You would have to write your own clustering classes. The reason why it won't work is that each singleton will be individual to a classloader and each tomcat accross the cluster will obviously have its own classloaders. The standard clustering only shares the sessions that are stored within the standard session manager in tomcat. -Original Message- From: Shey Rab Pawo [mailto:[EMAIL PROTECTED] Sent: 08 February 2005 17:44 To: Tomcat Users List Subject: Re: Session Objects Could you explain why this won't work across a cluster?

IllegalStateException: getOutputStream() has already been called for this response
I'm trying to write a servlet that handles
business logic exceptions by specifying in the web.xml the jsp error page
that I want to use for a specific Exception (see web.xml snippet below).
I have this working when I use response.getWriter() in the servlet
instead of response.getOutputStream() -- see sample servlet code
below. But, when I try to use the response.getOutputStream() approach
the jsp error page doesn't work and an IllegalStateException:
getOutputStream() has already been called for this response gets
thrown because the jsp is probably trying to get the OutputStream also.
Why does the response.getWriter() method
work even after headers/data have been written to the writer?
Is there any way to get the jsp error
page to work with the getOutputStream()?
I would like to eventually compress
the response stream, but from all the examples I've come across on compression
they all use getOutputStream.
web.xml contents:
error-page
exception-typeBookNotFoundException/exception-type
location/jsp/ErrorPage.jsp/location
/error-page
servlet contents:
public void doPost(HttpServletRequest
req, HttpServletResponse res)
throws ServletException, IOException {
PrintWriter out = res.getWriter();
//OutputStream out = res.getOutputStream();
res.setContentType(text/plain);
try
{
out.println(Line 1 of servlet);
//out.write(Line
1 of servlet.getBytes());
throw new BookNotFoundException(Book
doesn't exist);
}
catch
(Exception e) {
res.reset();
System.out.println(Caught exception:
+ e.getMessage());

Context element precedence
In the TC 5.5 doc under Server Configuration Reference it says: In addition to nesting Context elements inside a Host element, you can also store them: in the individual $CATALINA_HOME/conf/context.xml file: ... in the individual $CATALINA_HOME/conf/[enginename]/[hostname]/context.xml.default file: ... in individual files (with a .xml extension) in the $CATALINA_HOME/conf/[enginename]/[hostname]/ directory if the previous file was not found for this application, in individual file at /META-INF/context.xml inside the application files Is it the override attribute then who decides if it is the next context element who has precedence or not if there happens to be duplicate definitions of parameters or attributes?

I'm not sure exactly how tomcat/java interact with this, but it was not favorable. Other than for determining the number of threads to use for parallel GC, the JVM does not care how many CPUs there are. I don't know what Windows returns for the number of CPUs installed when hyperthreading is enabled, but you can determine that with the Runtime.availableProcessors() method. You really should be measuring performance by some measurement of actual workload completed, not CPU utilization. Turning off hyperthreading may actually reduce your overall throughput. (Then again, it might make it better - very application dependent.) You're right. I was measuring average response time. The CPU was just the bottleneck. My average response time under a specified user load actually decreased with hyperthreading off. My next step is to start analyzing the code:) Thanks for the pointer!

You agreed that I do not need to use apache, but your advice was explained to me using apache configuration file format. I just figured that you were giving me examples/ideas. Tomcat does not have an httpd.conf file, it has server.xml and web.xml and the format of these files are completely different from apache. Hence my confusion.

RE: using shared objects from tomcat
1) Your monitoring options depend on what unix(-like) system you are running on. On Linux, there's strace. On Solaris, truss. On HPUX and AIX? I forget. To do this PROGRAMMATICALLY to create a sandbox? Forget it. The Unix Approach is this: A) create a uid/gid with only the access that you want your code to have. B) Run tomcat under that UID/GID. If you want the shared lib code to have less access than Java code, you need to introduce a process boundary instead of using JNI. 2) Generally, you can get some clues on UnsatisfiedLinkError, in a pinch, by using LD_DEBUG or strace (or truss or whatever). 3) Read the JNDI-howto. I happen to have left behind some useful clues in there. However, the following might also be useful. A) Any .so has to be in java.library.path and in LD_LIBRARY_PATH. Any dependencies of the .so (visible with 'ldd', likewise). B) A native class can only be loaded in One Classloader. Tomcat has a bunch of classloaders. If you run without a security manager, you \can/ load a native class in a webapp class loader, but it will often cause you pain and suffering. If you undeploy and redeploy the webapp, chances are that the old classloader will still be around with the native class in it, unless you were amazingly careful with reference management. Thus, I always put native classes in the 'common' classloader by adding the jars to common.loader in catalina.properties. 4) I have come to believe that the shared objects that you use for JNI should be thin wrappers that make their own calls to dlopen/dlsym to find the guts of your code. This insulates you from the various stupid things that the JVM makers do from time to time in picking the wrong arguments to dlopen. 5) Consider using an RPC protocol to talk to a server written in C/C++ instead of using JNI in the first place. If the performance is acceptable, your life could be a lot simpler. -Original Message- From: Andreas Andersson [mailto:[EMAIL PROTECTED] Sent: Tuesday, February 08, 2005 3:32 PM To: Tomcat Users List Subject: using shared objects from tomcat Hi (again)! I still have problems useing a shared library from within a tomcat webapp. The same code works from a standalone appication but not from tomcat. If anyone can answer one or more of the following questions I would be happy. 1) Is there any way to log what a .so-file attempts to do without altering the source? This so that I can see if the .so tries anything funny thats not allowed from within tomcat. 2) Is there any way to get more information from an UnsatisfiedLinkError. Now that error is all I get, no reason or root cause at all. 3) What differs in how tomcat and a standalone java application loads libraries?

Re: IllegalStateException: getOutputStream() has already been called for this response
Your approach is bad but don't worry. If you have time, read something about
MVC. You will need it eventually.
To make your servlet work, try something like:
public void doPost(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
StringBuffer myOutput = new StringBuffer();
try {
myOutput.append(Here I'm not doing anything illegal);
if(true)
throw new BookNotFoundException(Book doesn't exist);
}
catch (Exception e) {
System.out.println(Caught exception: + e.getMessage());
throw new ServletException(Dummy Exception, e);
}
// you reach this only if no errors have been caught so no error page to display
OutputStream out = res.getOutputStream();
res.setContentType(text/plain);
out.println(myOutput.toString());
}

Subject: IllegalStateException: getOutputStream() has already been called for
this response
I'm trying to write a servlet that handles business logic exceptions by
specifying in the web.xml the jsp error page that I want to use for a specific
Exception (see web.xml snippet below). I have this working when I use
response.getWriter() in the servlet instead of response.getOutputStream() --
see sample servlet code below. But, when I try to use the
response.getOutputStream() approach the jsp error page doesn't work and an
IllegalStateException: getOutputStream() has already been called for this
response gets thrown because the jsp is probably trying to get the
OutputStream also.
Why does the response.getWriter() method work even after headers/data have
been written to the writer?
Is there any way to get the jsp error page to work with the
getOutputStream()?
I would like to eventually compress the response stream, but from all the
examples I've come across on compression they all use getOutputStream.
web.xml contents:
error-page
exception-typeBookNotFoundException/exception-type
location/jsp/ErrorPage.jsp/location
/error-page
servlet contents:
public void doPost(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
PrintWriter out = res.getWriter();
//OutputStream out = res.getOutputStream();
res.setContentType(text/plain);
try {
out.println(Line 1 of servlet);
//out.write(Line 1 of servlet.getBytes());
throw new BookNotFoundException(Book doesn't
exist);
}
catch (Exception e) {
res.reset();
System.out.println(Caught exception: + e.getMessage());
throw new ServletException(Dummy Exception, e);
}
}

Have you edited server.xml at all? It looks like you have a context
element along the lines of
Context path= docBase=${CATALINA_HOME}/webapps debug=0/
in your server.xml. This is bad. The default install uses Context
path= docBase=ROOT debug=0/ although it is commented out because
tomcat does this automatically by default anyway.

I click on

Re: using shared objects from tomcat

First of all, thanks for the answer, I've been fighting this one for
quite som time now.
1) Your monitoring options depend on what unix(-like) system you are
running on. On Linux, there's strace. On Solaris, truss. On HPUX and
AIX? I forget. To do this PROGRAMMATICALLY to create a sandbox? Forget
it. The Unix Approach is this:
This is a debian suggesting strace to be the one for me. Can I attach
strace to my .so-file or do I have to start tomcat via strace?
2) Generally, you can get some clues on UnsatisfiedLinkError, in a
pinch, by using LD_DEBUG or strace (or truss or whatever).
If I'm not misstaken tomcat ignores environment variables so how can I
set LD_DEBUG?
A) Any .so has to be in java.library.path and in LD_LIBRARY_PATH. Any
dependencies of the .so (visible with 'ldd', likewise).
java.library.path _AND_ LD_LIBRARY_PATH? Thats intersting and might very
well be the solution to my problem. As I just wrote I think tomcat
ignores these evironment variabels. I was under the impression that
LD_LIBRARY_PATH was the same as java.library.path, if that is not the
case then how do I set LD_LIBRARY_PATH?
Thus, I always put native classes in the 'common' classloader by adding
the jars to common.loader in catalina.properties.
Is it also OK to add .so-files? I have
grant codeBase file:${catalina.home}/common/- {
permission java.security.AllPermission;
};
in my catalina.properties. Would that suggest that if I only placed all
.so-files under /common they would be loaded or at least accessable?
4) I have come to believe that the shared objects that you use for JNI
should be thin wrappers that make their own calls to dlopen/dlsym to
find the guts of your code. This insulates you from the various stupid
things that the JVM makers do from time to time in picking the wrong
arguments to dlopen.
5) Consider using an RPC protocol to talk to a server written in C/C++
instead of using JNI in the first place. If the performance is
acceptable, your life could be a lot simpler.
Unfortunatly the codes in the .so-files isn't mine. It's a third party
product that we can't alter or even have altered for us.

removed. This problem only happened on Tomcat 5.5. 4.x/5.0 were fine.

RE: [OT]Attn developers of Tomcat and JK
Really this is way out of line. As everyone has said this is a free product with no formalized support structure, and no claims of any support. This list is here as a resource to those brave souls who are adventerous enough to work with the software. I might be overstating things here but there should be no one here that is surprised that there is no corporate help desk here. When I started out the only thing I had going for me was I was inquisitive and had access to log files, this list and google, thats all I needed. Three things you can do that will answer your questiion. Ask in a clear consise manner (I have had a problem with that on occasion), check and double check your settings (many times I have been the culprut in my own problem) and google the error. :) From: Eric Sandusky [EMAIL PROTECTED] Reply-To: Tomcat Users List tomcat-user@jakarta.apache.org To: 'Tomcat Users List' tomcat-user@jakarta.apache.org Subject: Attn developers of Tomcat and JK Date: Tue, 08 Feb 2005 10:11:03 -0600 To the developers of Tomcat and JK: As I can sense that not one single person is willing to respond to this issue, I can only assume that this tomcat-user community is worthless. Not only have I submitted this issue back 6 months ago, but a similar post was made by the user A jie twice within the last week. If you are too ashamed that your software is not reliable enough to be installed in a production environment, at least have the decency of telling us that. When I have to deal with user session data being sent back to the wrong client, sessions getting lost, and numerous log errors stating that the request/response cannot be fulfilled, I can only come to one conclusion.. Tomcat and the JK/JK2 connector are not reliable. See below and tell me that those messages would not cause problems for the client.

And doesn't it seem strange how the JK2 project has been mysteriously abandoned? Thanks for going off in a seemingly better direction only to jump ship and leave everyone SOL. It makes me think that this whole Tomcat development effort is more of just a hobby and not something to be taken seriously. If anyone is willing to contact me on this issue, I would be more than happy to talk one-on-one. If you want to tell me that this is not the forum for ranting about Tomcat or JK, it should be. If you want to blackball me from this community, go ahead, I'm not getting any help from it as it is. I can only hope that this message reaches the people who supposedly support this software and lights a fire underneath them to improve it or tell us that it just doesn't work.

I get a 404 error.
So I took it step by step to see if I made typos or something. If I
go to http://host:port I see the directory listing including myapp
This shouldn't happen. This means that myapp is a directory in the root
context rather than a separate context.
Have you edited server.xml at all? It looks like you have a context element
along the lines of Context path= docBase=${CATALINA_HOME}/webapps
debug=0/ in your server.xml. This is bad. The default install uses
Context path= docBase=ROOT debug=0/ although it is commented out
because tomcat does this automatically by default anyway.

I click on
myapp. There is nothing in the directory listing. I then add
/cgi-bin/script.cgi to the end, to make
http://host:port/myapp/cgi-bin/script.cgi. Same result: 404.
I then tried http://host:port/myapp/script.cgi. Same result.
I then tried http://host:port/myapp/WEB-INF/cgi/script.cgi. This time
it asked me if I want to open or download this file.
shrug
Any ideas?
Thanks.
