Re: book for servlet programming
3/ Download a copy of the servlet spec (java.sun.com) and give it a good skim. It's dry -- it's a spec, after all -- but it contains what every servlet developer should know. Sticking to spec-compliant code will make your apps container-agnostic, such that you can use Tomcat, WebLogic, etc with little difficulty. I second that whole heartedly. It is essential to understand that everything is driven by the specifications - make them your bibles. The O'Reilly Java Servlet and JSP Cookbook book is also a good secondary source.

How to create object when context app inits and make it accesible to context by JNDI
Hi all, i like to create an object when context app inits and make it
accesible to all context JSPs, classes, etc. by JNDI, i've used Resource
and ResourceParams in $CATALINA_HOME/conf/server.xml and resource-env-ref
in $CATALINA_HOME/context-app/WEB-INF/web.xml but it creates one new
instance everytime i run:
Context ic=null;
try {
ic=new InitialContext();
paramsWeb= (WebAppParams)
ic.lookup(java:comp/env/chua/WebAppParams);
.
.
.
}
Any ideas?
Thanks in advance

Releasing memory on undeploy
Hi, I'm one of the committers on commons-logging and am currently looking into memory-leak issues with j2ee/servlet-engine stuff when undeploying apps that use commons-logging. I see the following page in the tomcat FAQ states that classloaders cannot be garbage-collected in tomcat: http://jakarta.apache.org/tomcat/faq/deployment.html Can someone confirm this is in fact true, and if so explain why? Thanks, Simon - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: changing my web app and then deploying takes a lot of time!!!
Hi again, In my case, the application's WEB-INF/web.xml change does not trigger a reload although I have WatchedResourceWEB-INF/web.xml/WatchedResource in context.xml. No idea why this does not work. But a change of the application's context descriptor triggers a reload, e.g.: touch yourCatalinaHome/conf/Catalina/yourDotcom/ROOT.xml No idea why this works. Have you tried it?

Windows NT
Hi, Shouldn't TC install under (not manufacturer supported any more) Windows NT 4? I´m using a product called DeskNow and it uses Tomcat 5.x. Unfortunately (or not), ver 2.6 of the product started using ver 5.x of Tomcat. I use a retired WinNT box as the DeskNow Server, but, when upgrading to version 2.6, service registration failed with the following message on Dr. Watson: Title: desknow.exe Exception: access violation (0x0005), Address 0x77f92a66 In event viewer, the corresponding message is: The application, , generated an application error The error occurred on 2/22/2005 @ 11:10:20.763 The exception generated was c005 at address 77f92a66 (wcslen) Since WinNT is not supported anymore by MS, I was instructed by DeskNow Support to contact Tomcat support, in the hope that you can give somehelp. I'll not justify my choice of (unsupported) WinNT as my server for this application, but I'll say that it's what we have available now. Thanks for your attention and time, Best regards Serginho

As such, as long as you have a working java virtual machine you can run tomcat, regardless of what the operating system is. I'm 99.99% sure that it will still work on NT as a stand-alone program, so there's always that option as long as you don't absolutely *have* to run it as a windows service. [1] But java doesn't support the concept of a windows service natively. Tomcat does that via the commons-daemon library that provides some native code to do that on various platforms; see http://jakarta.apache.org/commons/daemon. I would suggest investigating what version of commons-daemon your Tomcat instance uses, then have a look at what platforms that version of commons-daemon supports. If the latest release has dropped support for NT then you might be able to install an old release of commons-daemon over what DeskNow bundles. There's also the possibility that the crash is not anything to do with Tomcat, but instead in some custom code provided by DeskNow. You said that service registration failed but I'm not sure exactly what that means. Are you sure the crash is occurring within some part of tomcat or commons-daemon? [1] Of course if DeskNow is just a java application, then you could also run it on Linux :-) Cheers, Simon - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

[tomcat-user] Postgres + JDBC
First of all, hello to the groupe. I'm a newbi as far as tomcat is concerned, so if this is really stupid, sorry for wasting your time. I'm trying to get a JDBC Data pool connection up using Tomcat and postgres SQL. My JNDI source is configured, and when I : Context initContext = new InitialContext(); Context envContext = (Context)initContext.lookup(java:/comp/env); DataSource ds = (DataSource)envContext.lookup(jdbc/postgres); I get a Datasource with all the details I entered. The problem is that when I try to connect, I get the following error: Cannot create JDBC driver of class 'org.postgresql.Driver' for connect URL 'jdbc:postgres://10.201.1.10/QCM' postgres-8.0.309.jdbc3.jar is in common/lib, yet removing it, or movining it to shared/lib or $WEBAPP/WEB-INF/lib doesn't change the error. I'm running postgresql 8.0 and tomcat 5.0.28. TIA for your time, all suggestions greatly appreciated.

Re: Logging in Tomcat 5.5
I'm *guessing* you're facing some of the issues I have been. I believe you'll essentially need to set up a separate LoggerRepository (based on classloader, not thread or contextual class loader) and provide separate config files for each. I've got log4j.jar in my WEB-INF/lib, I'm using my own static/classloader-based LoggerRepository, and this keeps Tomcat's logs using their own LoggerRepository and a separate logging configuration. I'm still not to where I want to be with this, but it's a far cry from the out-of-the-box mess that occurs with log4j and commons-logging. -- Jess Holle Joy Kenneth Harry wrote: Hi, I have a webapp in tomcat. I am using a separate Log4j.xml for it, in its WEB-INF classes folder. I've also put a Log4j.xml in TOMCAT_HOME/ common/classes and set it to false so that I do not get the general Tomcat logs. But even then my project logs are getting mixed with the TOMCAT logs.

This has to do with the applicationresources.properties files that you have configured in your struts-config.xml. It's not able to find the properties file that you have specified under the message-resources XML element, in the struts xml config file.

Tomcat behind IIS
Hi all, I installed a tomcat 5.0 behind an IIS server. Everything works fine with the connector. Now, I would like that Tomcat only accepts connections from this IIS server and not from others computers (still accessible from http://myhost:8080/myApplication http://myhost:8080/myApplication ). Is there a simple way to do this in server.xml (or other tomcat config files) or do I have to install a firewall ? Thanks in advance. Fred.

sure, just go into your server.xml and remove the web connector Connector port=8080 / I'm using the minimal server.xml (slightly modified) so there may be more parameters in yours.

Re: Thanks Trond
Hi, at office I am using tomcat 5.0.25. In that server my jsp's are running but when I try to run servlet in IE the browser tell me download the war file instead of executing it. How do you deploy your war file? I'm guessing that you have not used the manager since you could not login? The only way I can make sense of this, is if you have copied the war file into $CATALINA_HOME/webapps/ROOT/ and try to access it from your browser by entering http://localhost:8080/myapp.war. If this is the case then you should copy the file into $CATALINA_HOME/webapps instead and tomcat will automatically expand your war file into a directory named after your war file, and you should be able to access your jsp files by entering http://localhost:8080/myapp/myfile.jsp If you have deployed your war file correctly I don't know what is causing this behaviour. - Trond - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
deleteOnExit doesn't seem to be working for session temporary files..
In our setup, we have JSP's that create a temporary file with the deleteOnExit flag set. The session timeout (getMaxInactiveInterval) appears to be the default of 1800 seconds (30 minutes). We are blasting our servlet container (tomcat and jetty) with JSP fetches (that don't handle cookies - http_load if you are curious as to what we are using) and noting that these files stick around till the servlet container itself quits (the java process goes away). At that point ALL the files are deleted, and it can take HOURS in some cases to do so. Is this expected behavior? We think that these files should be deleted when the session expires. That seems like the right thing to do. Jetty appears to perform similarly except that it actually CRASHES with outOfMem errors after enough files are opened this way. Tomcat seems more stable. Jetty 4.2.17, Tomcat 5.0.16. Thanks for all help. - Joseph - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

memory usage
Hi everyone, I'm not quite sure where to post this problem - the tomcat, tapestry or cayenne mailing list - but here goes... I have an app built on the mentioned technologies. I click arround and monitor the memory usage (using the Win task manager - good enough for rough measurements). The memory usage seems to grow up to a 100 MB (Cayenne accesses a single table of about fifty attributes and a 1000 rows - don't ask) and sometimes - I can't reproduce the problem now - the app brakes when trying to open a new page. The exception says something about not having enough memory. Ring any bells, anyone?

Cluster Deployment Question
I am ready to set Tomcat up in a clustered environment. So to test I have installed two instances of Tomcat 5.5.7 on the same XP machine. One listens on 8080 and the other on 8081. I configured the server.xml as follows... Cluster className=org.apache.catalina.cluster.tcp.SimpleTcpCluster managerClassName=org.apache.catalina.cluster.session.DeltaManager expireSessionsOnShutdown=false useDirtyFlag=true notifyListenersOnReplication=true Membership className=org.apache.catalina.cluster.mcast.McastService mcastAddr=228.0.0.4 mcastPort=45564 mcastFrequency=500 mcastDropTime=3000 / Receiver className=org.apache.catalina.cluster.tcp.ReplicationListener tcpListenAddress=auto tcpListenPort=4001 tcpSelectorTimeout=100 tcpThreadCount=10 / Sender className=org.apache.catalina.cluster.tcp.ReplicationTransmitter replicationMode=pooled ackTimeout=15000 / Valve className=org.apache.catalina.cluster.tcp.ReplicationValve filter=.*\.gif;.*\.js;.*\.jpg;.*\.htm;.*\.html;.*\.txt; / Deployer className=org.apache.catalina.cluster.deploy.FarmWarDeployer tempDir=/tmp/war-temp/ deployDir=/tmp/war-deploy/ watchDir=/tmp/war-listen/ watchEnabled=false / /Cluster ...with tcpListenPort as 4001 in one instance and 4002 in the other. With watchEnabled false on one but true on the other. The Tomcat instances start fine and both indicate... INFO: Replication member added ...when started. This tells me that they see each other. When I try to deploy a web-app by dropping it in the war-listen directory I get... SEVERE: Unable to install WAR file java.io.FileNotFoundException: C:\tmp\war-deploy\clustertest.war (The system cannot find the path specified) ...okay, so that doesn't work. So I try to deploy through the manager on 8080 using Select WAR file to upload... The 8080 server says: WARNING: Manager[/clustertest], requesting session state from org.apache.catalina.cluster.mcast.McastMember[tcp://123.321.21.25:4002,1 41.254.21.25,4002, alive=227500]. This operation will timeout if no session state has been received within... The 8081 server then says: Mar 18, 2005 3:03:35 PM org.apache.catalina.cluster.tcp.SimpleTcpCluster messageDataReceived WARNING: Context manager doesn't exist:/clustertest ...then the 8080 server waits, then times out and says... SEVERE: Manager[/clustertest], No session state received, timing out. ...any ideas? Seems like the Tomcats are talking and trying, but can't send the WAR from one to the other.

The javadoc for File.deleteOnExit very clearly states that the file is deleted *when the virtual machine terminates*. A session is *not* a virtual machine. I suggest you use a SessionListener object instead; this should be invoked when the session expires, and you can delete the files then.

Overriding the browser language setting?
Hi there all! I'm trying to override the default struts/tomcat code that chooses an ApplicationResources.properties file based on the user's browser language setting. I'd like to manage which language to serve up on my own (or based on an item in the user's session). Does anyone have any pointers on how to do this? Normally I would bash my head against an issue like this for weeks and weeks before finally posting, but in this case, its an emergency and time is short. Thank you for any and all help any of you incredibly talented and intelligent people could provide. /kurt - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Releasing memory on undeploy
currently looking into memory-leak issues with j2ee/servlet-engine We have about a dozen apps on 2 tomcats that have 800MB each in linux (5.0.25), and they are not huge apps, but after a few manager reloads the tomcat is out of memory. Is this related? You said undeploy, but maybe reloading is also a problem. Also, if we let the server run for a while, we cannot add new apps either. I suspect we need to profile and look for memory leaks, but I thought it would mention it. Chris - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

By undeploy I mean throw away the classloader associated with the deployed component, which reload will also do. The problem is that both commons-logging and commons-beanutils use the Singleton pattern. And the Singleton pattern is *extremely* hard (possibly impossible) to implement correctly in a j2ee-style environment when a class might be loaded via a shared classloader. Tomcat includes a workaround for commons-logging which appears *to me* to be a complete fix for commons-logging leaks (though maybe not a very elegant one): it calls org.apache.commons.logging.LogFactory.release(this) from class WebappClassLoader. However there have been reports of leaks when using commons-logging despite this; I need to try to set up some testcases to determine what's going on, but testcases involving garbage-collection and complex classloading setups will be tricky to create. If you do find anything from profiling your app, please post the info to this group (and/or me). Note that I'm going to be away for the next three weeks, but will try to pick this topic up when I return.

[Slightly OT] MVC approach when JSP are not allowed
I am working on a project that uses servlets exclusively. I would like to take advantage of a Model-View-Controller system in order to develop my servlets. For the last servlet project I worked on, I was in charge of the back-end data processing and did not have to mess with HTML. This time I do have to roll up my sleeves and play with HTML. So I ask the question. Since the requirement that I have is to use servlets only, can I use something like Struts or Java Server Faces? I am reading some information and it looks like they both rely on JSP to ge the job done.

Delegate flag for classloading (ATTN: Remy Maucherat)
Hi, I see here that there is an option for the webapp-specific classloader to use parent-first classloading instead of the (default) child-first classloading. Can someone suggest why this might be useful? Clearly someone thought so, but I can't see any point in it. It is in catalina since version 1.1 (committer: Remy Maucherat). See delegate option in this page: http://jakarta.apache.org/tomcat/tomcat-5.0-doc/config/loader.html Using this option makes life exceedingly complicated for some libs like commons-beanutils and commons-logging, so I would like to know under what conditions someone might enable this feature.

Authentication for streaming file (OT)
Slightly off-topic -- Tomcat related
I have a servlet that is invoked by clicking a hyperlink that is
rendered by a JSP running in Tomcat. The servlet receives a file path
parameter in the HTTP request, and then streams that file to the
requesting client. I have a security-constraint/ defined in Tomcat for
the JSP, requiring basic password authentication. However, if I define
the security-constraint/ so that it applies to the servlet also, then
the following error occurs when the servlet attempts to stream the file
to the client.
The browser presents the file info and prompts to save or open the file,
but then when the actual streaming is attempted, the browser reports
that the site is unreachable. This is apparently caused by the lack of
any authentication during the file streaming operation, because when I
define the security-constraint/ so that it applies to the JSP but not
the servlet, the problem does not occur. I don't really understand why
it behaves this way, since the servlet was invoked with proper
authorization, and the problem occurs only when the servlet starts
streaming a file to the client. But it does seem to be an authorization
problem, since it goes away when I don't constrain the servlet for
authentication. I can operate this way, but then my JSP is protected and
the servlet is not.
Is there a way to specify authentication parameters during the file
streaming operation? Does anyone have an explanation for what I'm
experiencing? Here's my servlet code:
public class FileSender extends HttpServlet{
protected void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException{
String filename = request.getParameter(file);
File file = new File(filename);
MimetypesFileTypeMap mimeTypes = new MimetypesFileTypeMap
(C:\\Program Files\\Java\\jdk1.5.0_01\\lib\\mime.types);
String mime = mimeTypes.getContentType(file);
response.setContentType(mime);
response.setHeader(Content-Disposition, attachment;
+ filename= + file.getName());
FileInputStream in = new FileInputStream(file);
OutputStream out = response.getOutputStream();
byte[] buf = new byte[1024];
int i = 0;
while((i=in.read(buf))!=-1) {
out.write(buf, 0, i);
}
in.close();
out.close();
}
}
And here's my web.xml. With this configuration, the file downolad fails
as described above. To make it work, I remove the second url-pattern/
element as indicated.

A JSP page gets converted into a servlet; in a sense JSP is just a different syntax for writing servlets in. If the reason is simply that the architects don't want run-time compilation of files, or don't want a java compiler available on the machine then JSPs can simply be precompiled.

Using RealmBase.Digest(...)
I'm writing an app to create user id/pw's in a db for use by realms. I've read the realm HOW-TO page. But I have two implementation questions: 1) the page says: To use either of the above techniques, the $CATALINA_HOME/server/lib/catalina.jar file will need to be on your class path to make the RealmBase class available. I'm doing this in a servlet. The way I typically make jar files avail to servlets is to put them in the WEB-INF/lib dir or in the Tomcat common lib. I don't think I should be making a copy of this jar or moving it around. How do I force a jar into a webapp's classpath? Is there a tag I can put in web.xml to set classpath or add jars? 2) There are three parameters on the Digest() method. The third parm is 'encoding'. What encoding should I be using? I assume it needs to match whatever encoding the realm code is going to use when it compares the digested password. What string do I use for this parm? Thanks.
