Re: Finding Version Of Tomcat On Unix?
As with the recently asked question on which java version is in use, you should be able to glean that from the manager webapp. http://localhost:8080/manager/html (replace localhost and 8080 with appropriate values for your installation) Log in with a user that has the manager role and it should offer you lots of good information on the status of tomcat. --David [EMAIL PROTECTED] wrote: Hello List!

Re: accessing files/dirs.....
Ok... I think I'm starting to see the picture here. You want to be able
to write a jsp that can list the directory contents of a folder. This
is very crude, no error checking, untested, etc. but you'll catch on
ul
%
String reqParameter = request.getParameter( directory ) ;
URI dirURI = this.getServletContext().getResource( reqParameter
).toURI() ;
File dirFile = new File( dirURI ) ;
if ( dirFile.isDirectory() ) {
String[] fileList = dirFile.list() ;
for ( int index = 0; index fileList.length; index++ ) {
out.println( li + fileList[ index ] + /li ) ;
}
}
%
/ul
And it does comply with the servlet spec.

Re: Number of Servlets Tomcat Container Creates
Quoting the spec here (SRV.2.1 of servlet spec 2.4): The handling of concurrent requests to a Web application generally requires that the Web Developer design servlets that can deal with muiltiple threads executing within the service method at a particular time. Generally the Web container handles concurrent requests to the same servlet by concurrent execution of the service method on different threads. That right there suggests strongly that you should avoid class instance variables. On the thread front, the threads I believe are created by the connectors to handle incoming requests. Connector threads aren't tied to any specific webapp or servlet. They call the appropriate method of a servlet and pass in a HttpServletRequest and HttpServletResponse object. --David Evan J wrote: Hi, I am new to servlets and web container. From what I have read so far, I've gotten an impression that the web containers, in this case Tomcat, create only _one_ instance of each particular servlet upon start/[re]deployment of a web application. Any request to such servlet would cause a container to spawn a thread that would call upon this servlet instance's methods (service()...). My first question is, that under any circumstances, does the container create a second instance of a servlet (obviously we are talking about a servlet with a unique registered name not all the servlets in the context)? I tried to verify this by placing `this' in a Hashtable during doGet/Post() call to see whether the Container creates a new one which apparently doesn't but I just want to make sure if my assumption is correct. If that's correct then it does not matter the servlet's variable be an instance variable or a class variable. Another question that arises (relating to the first question), does every newly created thread with the help of Container get accessed to that single servlet instance and pass the request/response objects to the servlet? Wanting to dig deeper into details, and I know this may not be an appropriate mailing list, but where does Tomcat container management actually create these threads? What java file to be more specifically?

A further investigation of Tomcat source code reveals that, indeed, the servlet definition class such as `org.apache.catalina.core.StandardWrapper.java' implements a singleton design in creation of each servlet (in allocate() method). Unless of course, servlet implements a single thread model, in that case, a stack structure is used to handle pool of such servlet instances. What I am still inclined to figure out is at what location(s) does the container creates threads to handle servlet requests/responses?

You should remember servlet engines can be implement the spec in any way they see fit. They are only required to comply with the spec. Anything not spelled out there is subject to interpretation. Suffice it to say servlets in and of themselves should be as stateless as possible as various threads call on their methods. Stuff that persists for the life of the request, session, or application are stored as attributes of the request, session, or servletContext respectively. I'll step back here and let a tomcat developer explain the internals of tomcat. I've only ever had a cursory look at the tomcat internal source code. I do know the threads aren't created per request -- they are pooled and the pool creates/drops threads as necessary.

Re: apache-tomcat on an ia64 rhel4?
Tomcat is really a whole service environment for running java servlets and jsp. Don't think if it in terms of CGIs that just run for the request and close down. Tomcat is more akin to Apache's httpd, listening ports and responding to client requests on the http or https protocol. It can be proxied with Httpd if you want using either straight http reverse proxying or a custom AJP protocol. Tomcat is fully open source and can run with the Sun JRE as of version 5.5 (maybe 5.0, but I'm not sure without looking it up). Don't use gcj -- it's not a complete enough java environment. I've heard IBM's implementation of java is pretty good but haven't tried it. --David Jeff Sadowski wrote: I'm still really unclear about what tomcat is.

Re: Same session for one IP
None that I no of. More to the point, it's a security issue to have all the browsers behind one IP share a common session. Witness how cable routers can share one IP with an entire apartment building. Would you really want your neighbor with the super loud metal rock to see your credit card statements? All browser windows spawned from a single process can share (and often do to the frustration of some web developers). So, if you use New Window or Ctrl-N from within IE you'll get the same session as the window that started the session. Firefox does the same thing regardless of whether you open from Explorer or New Window in the File menu. Is there a reason you need to guarantee all the browsers from a given user have the exact same session? --David kz wrote: Hi, Is there any option in Tomcat which can assign a new session ID only if the IP address is changed and not a browser window?

Re: getting context path name
request.getContextPath() should supply what you need. If the webapp is
the ROOT webapp, it will return an empty string. That just makes it
easy to write stuff like:
img src=${pageContext.request.contextPath}/images/myMasthead.jpg /
If you really need the ROOT webapp to return /, then you'll just have
to test for an empty string and handle that as a special case.

Re: install DBCP and mm.mysql 2.0.14 (JDBC Driver) and test app, get class compile error.
There's no reason I know of to have .classpath or .project in the webapp. The servlet spec doesn't define them and tomcat doesn't use them. I would imagine these are specific to the development environment you are working in. I've seen posts from other people integrating PHP with Tomcat, but don't do it myself. Hopefully someone else on the list might offer some helpful tips there. Glad you got things working. --David Wayne Bragg wrote: Thank you once again David, Yes I did upgrade the mysql driver, made the appropriate changes, and now it's all working fine!

Re: install DBCP and mm.mysql 2.0.14 (JDBC Driver) and test app, get class compile error.
A few things to consider ... 1) What version of tomcat are you using? What follows is based on using version 5.0.x. The syntax for configuring JDBC resources in 5.5 is a little different. 2) mm.mysql 2.0.14 is VERY old. What version of MySQL Db server are you using? You may want to take a look at the MySQL website for an updated driver .jar file. I believe the current driver version is Connector/J 5.0.5 3) The mm.mysql driver file has to be in common/lib. That's because the tomcat server itself has to be able to access the driver when setting up the db pool before your webapp even loads. 4) If using the tomcat internal database pooling, there is no need for adding commons-dbcp.jar or commons-pool.jar as tomcat has a slightly refactored version of commons-dbcp already. The refactoring was only a package name change to avoid collisions with webapps that use commons-dbcp directly. Only add those jars if you have some code of your own using classes in the packages org.apache.commons.dbcp or org.apache.commons.pool. 5) The stack trace cited below is in regards to your test jsp file. Class files need to be compiled before deployment as tomcat doesn't compile them itself -- it only compiles jsps. To fix the error below, compile DbTest.java to DbTest.class and place it in WEB-INF/classes/foo or in a .jar archive in WEB-INF/lib. There's a start.

Answers inline below. --David Wayne Bragg wrote: Thank you David, I was suspicious about the .java needing to be compiled and the commons-dbcp.jar and commons-pool.jar being unnecessary. What about commons-collections-3.2.jar is that necessary or does commons-el.jar have what is needed? Commons-el.jar is all that was in there to start with. You've given me enough to go on to fix this and make this work. I thank you again.. If commons-el.jar was all that was in common/lib, only add the mysql driver jar. commons-collections shouldn't be needed except by your project if you use it. Do you think it's better to allow Tomcat to handle the MySql or have PHP and MySql handled by httpd and pass the java related calls on to Tomcat? I just finished reading an article that explains how to set it up this second way and have to admit it would be better for me in the SHORT run as I have pre-existing code that wouldn't require rewriting other than adding NEW java code which is the reason I'm doing this in the first place. IMHO it's a cleaner solution if you can get this all in tomcat or php. Having part in one and part in the other just makes things complicated and hard to work with. Also 97 and Visual J but it doesn't appear to be able to save .class files. It looks like it just puts the class code into the .exe at compile time.

Re: Mysql timouts...
If you read through http://tomcat.apache.org/tomcat-5.5-doc/jndi-resources-howto.html, you'll find the validationQuery attribute is used to test connections before they are borrowed from the pool. The query can be as simple as select 1. As a side note, drop the autoReconnect=true from your database url. It's not recommended and actually does not prevent SQLExceptions on connections that go stale. It just restores the connection for the next request after the exception. The MySQL website has further information regarding what autoReconnect actually does.

Re: where to store user-generated files?
I'm sure this is horribly insufficient, so I would recommend reading the
servlet spec. It's not all that bad a read as far as specifications go
and you can learn a lot about how tomcat operates.
If you have a servlet mapping all *.jpg to some servlet myServlet in
web.xml, web.xml also has another section where the servlets are
individually declared. In there you'll find the class that backs the
servlet named myServlet. All that means is the request for the
resource goes to that specific servlet class to be handled. What the
servlet does with it is open-ended. In the case of the default servlet,
it basically calls sc.getResourceAsStream( request.getServletPath() +
request.getPathInfo() ) and returns the contents of the file to the
client. That's over simplified -- the real default servlet does some
security checks to be sure it's not returning something it shouldn't and
set's the mime type in the response, but you get the idea.
sc.getResourceAsStream is aware of the webapp's location in the
filesystem and takes care of finding the resource in the webapp's folder.
sc.getRealPath will only return a full path to a file if the webapp is
NOT compressed in a web archive file (.war). From within a .war file,
it always returns null and isn't recommended except in rare cases where
you might want to write access. This is all in the spec.
Servlet 2.4 spec is available at
http://jcp.org/aboutJava/communityprocess/final/jsr154/index.html

The servlet mapping seems to me to tell tomcat anytime you have a

real file system said jpeg is stored, does it? So, when you call
sc.getRealPath(), how does the servlet context know where to go?
Doesn't there have to be a mapping or alias somewhere (server.xml,

Subject: Re: where to store user-generated files?
Looks like roll your own then!
A few thoughts on the matter - maybe someone could add to them?
It should be easy to map requests for images to a servlet, which can
then find the appropriate image file wherever it might be ( within or
outside the server ). Like this in the web.xml file:
servlet-mapping
servlet-nameservletName/servlet-name
url-pattern*.jpg/url-pattern
/servlet-mapping
?
But how is the image then added to the reponse? Another servlet (
behind the scenes - I am actually using the Spring framework ) is
handling the request/response. Can the request/response be passed to
the image-providing servlet for the images within a page to be written
to the reponse in this kind of way:
// This method is called by the servlet container to process a GET
request.
public void doGet(HttpServletRequest req, HttpServletResponse
resp) throws IOException {
// Get the absolute path of the image
ServletContext sc = getServletContext();
String filename = sc.getRealPath(image.gif);
// Get the MIME type of the image
String mimeType = sc.getMimeType(filename);
if (mimeType == null) {
sc.log(Could not get MIME type of +filename);
resp.setStatus(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
return;
}
// Set content type
resp.setContentType(mimeType);
// Set content size
File file = new File(filename);
resp.setContentLength((int)file.length());
// Open the file and output streams
FileInputStream in = new FileInputStream(file);
OutputStream out = resp.getOutputStream();
// Copy the contents of the file to the output stream
byte[] buf = new byte[1024];
int count = 0;
while ((count = in.read(buf)) = 0) {
out.write(buf, 0, count);
}
in.close();
out.close();
}
( from http://www.exampledepot.com/egs/javax.servlet/GetImage.html )
I'm off for a walk to mull it over - any suggestions while I am out
and before I get to experimenting will be most welcome.
Thanks,
John

Re: Expression Language in JSP and JasperException
Ok. I'm not overly familiar with Stripes, so you'll have to bear with
me a little. I can think of a few ways to handle this.
First, look at what makes a request from calculator.jsp unique. You
could use the referrer header, the value of a submit button, or the
presence of the equation request parameter. Below is an example using
the submit button:
c:if test=${(param.submitBtn == 'Calculate') and (actionBean.result !=
null)}
pThe answer is ${actionBean.result}/p
/c:if
A better solution would be to name the actionBean that's a result of
CalculatorActionBean something more descript than just 'actionBean' like
'calcBean'. The main advantage here is it's simple and you could use
your original expression language test -- just change the name of the
object being tested:
c:if test=${calcBean.result != null}
... display the result
/c:if
A more complicated solution if you can't change the name of 'actionBean'
might be to test the type of actionBean like...
c:set var=calcAvailablejsp:expression
(request.getAttribute(actionBean) != null)
(request.getAttribute(actionBean) instanceOf
com.some.packages.action.CalculatorActionBean )/jsp:expression/c:set
c:choose
c:when test=${calcAvailable and (actionBean.result != null)}
pThe answer is ${actionBean.result}/p
/c:when
c:when test=${calcAvailable}
pSorry, I couldn't understand your equation. Please rephrase it.../p
/c:when
c:otherwise
!-- Just logged in. Display the form. --
/c:otherwise
/c:choose
The essential point of this is testing for a property to be null is not
the same as testing for it's presence. You'll have to know if it has a
property before you can test the property for null.

Hi David,
Ok forgive me now, but this is getting confusing. Where does
result come into this picture? Were you expecting actionBean to be an

Sorry for mixup. I've just thought that it is just about some option
in Tomcat configuration or something, and I haven't knew it. Like I
see... It may be not. :(
Here goes more background.
login.jsp (handled by LoginActionBean class) redirects after
submission login form to calculator.jsp. After submition form from
calculator.jsp (what is handled by CalculatorActionBean class) it
returns to calculator.jsp and shows the result of mathematical
equation. Sources of calculator.jsp and it's class are placed below.
Problem shows when I'm submiting from LoginActionVean to
calculator.jsp. Like I wrote before, LoginActionBean doesn't have
result field because it doesn't need it. But JSP (in this case used by
two classes) expects result in:
46:c:if test=${!empty actionBean.result}
47:Result: ${actionBean.result}br/
line.
Here actionBean could be an instance of different class.

Re: Get rid of 8080 port in Tomcat 3.3
I haven't tried it on such an old version of tomcat, but I would think jsvc from the commons-daemon project would work here. http://jakarta.apache.org/commons/daemon It essentially allows you to start tomcat as a privileged user long enough to grab the port and then drop back to a low privilege user for general running. --David EDMOND KEMOKAI wrote: 80 is a privileged port on *nix systems, you'll need to run tomcat as root (generally not recommended).

The problem is that there could be a class that has no property with
name result. In another case there could be another class (bean) that
has such property (than of course it works fine, but at first case
Tomcat throws exception).
Maybe but let's keep debugging simple. The expression language is

Re: Can't find classes in jar files in WEB-INF
No just got busy with work. Given what you provided in your last post, it seems to come down to permissions or something overlooked. Are you running the security manager? Have you checked file permissions? Did you restart tomcat (or at least restart the webapp) after building the .jar file and placing it in WEB-INF/lib?

If you output xml, amp; still gets amp; It is meanless to create a not well formed xml. I don't remember what the output method text or html makes. Fair enough. When you put amp; into your XSLT, the processor sees it as entity:amp. When you write that out, the exact display depends on the output format. If it's emitting XML (or XHTML), you get amp; right back out. But, if you're outputting HTML (?) or text (definitely), then you get ''. If you want to emit amp; in text mode, you'll definitely have to double-up the amps. The problem is that JSPX is not XSLT. It's really JSP with some extra junk thrown in. Fortunately for me, I don't have to use it ;) Yes, I start to understand the ins and outs. Perhaps the spec writers just could not imagine, that someone will use jspx to do what it is great for, to produce xml ;-) So I'll go for my filter and wait for future jsp specs which will include something like jsp:output preserve-xml-entities=true / or jsp:output-method=xml / Similar directives for omitting XML declarations etc. are already included. i'll weigh in late with this thread... how then do i differentiate an ampersand that i need to process in the source document? in general there are 2 use cases for ampersands in xml generating xml docs: 1. xml source doc needs to process/contain an ampersand 2. xml generated doc needs to process/contain an ampersand the solution that the spec implements is double encoding in the source document - and it makes complete sense if you consider the two cases above; even if it doesn't make immediate, intuitive sense to an end user who is moving from the JSP to JSP Document format and who is only considering the 2nd case. the JSP document format has some strengths but also some practical weaknesses which is probably why it's adoption hasn't been as widespread... p -chris I'm sorry I missed most of this debate yesterday :-( Admittedly this can be a prickly issue from the jsp compiler stand point in trying to know when an is just a and when it's an entity for output to a (x)html or xml response. I have two thoughts that are probably better served on the tomcat-dev list or as comments to the spec committee: 1. Xml spec allows for material to be escaped in the source with ![CDATA[ . ]]. I've done this with jspx files that have included jsp:scriptlet sections. It's easier than trying to make sure all the special characters in the java scriptlet source are properly referenced. 2. It would be nice if the compiled resulting servlet paid attention to the type of the response and handled entity references properly on output. Text/binary/misc types get a dereferenced entity while (x)html and xml output leaves the entity intact as stated in the source jspx. I appreciate the problem as the output doesn't necessarily have to be just (x)html or xml. Sometimes the output is straight text or a binary format of some sort. Maybe the end solution is an attribute of the jsp tag that defines the response type. That would maintain backwards compatibility with existing jspx sources. --David - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Tomcat and MySQL sync problems
It appears your code is holding on to a connection to the database. Bad design practice. Review your code for any place that might keep hold of a connection between requests and make sure the connection is closed. Also, If you haven't done so yet, use a database connection pool. If using tomcat's built-in one, set testOnBorrow to true and set validationQuery to something simple like select 1. The idea being that the connections will be validated just before they are borrowed and used, closed and recreated if they fail. Lastly, please avoid autoReconnect=true in the connection url as the first query will still error out. There is documentation on mysql's site recommending this option not be used. --David Scott Purcell wrote: If I remember correctly, MySQL basically disconnects and shutdowns after a certain amount of time.

Re: datasource-realm troubles
I would guess from the outset that your Context.xml file isn't being used. Where are your putting it and what are you naming it? What's the name of your webapp when deployed? Quick checks: 1. It has to be named to match your webapp if your are storing it in Catalina/localhost and deploying an expanded webapp. If the webapp is named fubar, then the file should be named fubar.xml. 2. If deploying a .war file, it has to be named context.xml (note: case is important) and stored in the war files META-INF directory. --David Walter, Oliver (BR/ICI3) wrote: Hello, i have some trouble using a datasource realm in tomcat 5.5.20, jdk 1.5.0_09.

Re: tomcat Webapp security.
The best method I can think of is to store the jsp in a directory outside your tomcat and outside your webapp. Then configure the path to the storage in either the context.xml or web.xml for your webapp and use a ServletContextListener to load up an application scope attribute with the path. Lastly a slightly modified version of the default servlet could offer up the jsp files as type text/plain. The benefits of storing the files in a location outside tomcat and the webapp include easy upgrade of both and inhibiting execution of the jsp. --David Sachin Patel wrote: I have a web application and a functionality to be able to upload files to one of the folders inside it and be able to access it using direct link URL. now I am wondering if someone uploads .jsp file, how would I stop tomcat from compiling and running that file when someone requests that same file using direct link.

Re: Cannot create JDBC driver
Ok ... I'll bite. What's a realm got to do with the original post? The OP is just trying to setup a database pool via tomcat's built-in JNDI. OP -- Your code didn't match completely with the example code on the tomcat website. Here it is matched up with what's in the docs: InitialContext initContext = new InitialContext(); Context envContext = (Context)initContext.lookup(java:/comp/env); DataSource ds = (DataSource)envContext.lookup(jdbc/Library); The only two real changes here are 1) a missing / mark in between java: and comp and 2) the return of new InitialContext() is of type InitialContext.

Re: Adding a virtual host in Tomcat 5.5
First thing to realize is this is not like setting up PHP. JSPs aren't meant to live on their own like what you've setup below. Consider pointing your tomcat virtual host to /home/username/webapps. Then create a folder /home/username named ROOT (case is important here) and place your .jsp file in it. Next, add a folder named WEB-INF (case is still important) under ROOT and then a basic web.xml file in that new folder. This is the basic architecture of a web application. Second, I would HIGHLY recommend you read the servlet spec. It's not nearly as dry as reading an IEEE spec and you'll learn a lot about what's expected of the app as well as the servlet container.

Re: MOD_JK Redirection issues
I can see how the server might decode %2f in the path to /. The % character is a special character in urls and should be decoded. If you really mean for the url to literally include '%2f' as part of the file name, I would think the url should be: http://xxx.xxx.xxx/APIServer/authz/list/master%252fAB?apikey=WEB_INTERFACE_API Note I replaced the % character with it's encoded form %25, Having said that, I don't think it's a good idea to use special characters like % as part of the resource name. It creates nothing but headaches as the server has to figure out whether the url has already been normalized or not. --David Jagadeesh wrote: Further to my last mail, whenever I try accessing this url http://xxx.xxx.xxx/APIServer/authz/list/master%2fAB?apikey=WEB_INTERFACE_API the browser shows exactly the below response Not Found The requested URL /APIServer/authz/list/master/AB was not found on this server.

Re: TOMCAT 1.4
Tomcat is typically installed as a service using commons-daemon from http://jakarta.apache.org/commons/daemon. As a result, it's process name in any install I've done is jsvc. You might also see it as java if you start it using a shell script directly. Individual netstat commands change from os to os, but in Mandriva Linux, executing netstat -tlnp as root will list all the listening TCP ports and the process names. Something similar might help you identify both your tomcat process when running and what's listening on port 8080. --David tuosu wrote: Hello Charles, Honored to see your post, since i have seen your wonderful, worthful posts.

Re: session#getId changes during doGet invocation under heavy load
Hmm... I can see two senarios that can cause this situation: 1. Your sessions are configured to be way too short. I'd recommend at sessions live at least until the request times out. 2. You have a reference to the session in a servlet instance -- either directly or indirectly. Keep in mind that servlets are recycled between requests and should be entirely stateless. Class instance properties should be avoided. In this case an old session is continuously reused for several requests even after it's been invalidated. Even if these two suggestions aren't an exact fit to your issue, maybe they can seed some ideas on what's going on. --David Peter Coppens wrote: Actually it just seems to be related to the fact that under heavy load the db connection starts to take longer than the timeout. Apparently, a call to request.getSession() somewhere in the middel of the doGet processing will also trigger invalidating the session, which is kind of a nuisance as one should then apparently constantly check whether the session has not expired during request processing. I assume this is Servlet spec compliant, but it does seem to make my life rather complex. Would there be anyone having any suggestions to deal with this.

I have done some further research and I have the impression that there is some kind of race condition where a session that is being removed because of a timeout is also handling requests.

If I crank up the timeout, seriously reducing the chances a session times out before it has completed all the client requests it is supposed to handle during the test, the problem does no longer occur.

Martin -- That doesn't answer the question. Where is there a connection between the maxThreads and the number of users defined in tomcat-user.xml? As far as I can tell, the only way number of users in tomcat-users.xml can influence anything is 1) the amount of memory needed to hold the memory realm datastructure in memory and 2) the amount of time needed to iterate over the list to the current user's record. The set of users in tomcat-users.xml would have to be huge to make and significant impact on performance.

Re: Peak load of Tomcat-powered server(s)?
I knew somewhere in the past someone had done some performance testing against static content. After a bit of googling, I found this paper detailing some performance testing with regard to various JDKs and different sizes of static png files: http://cvs.apache.org/~woolfel/benchmark_summary.doc With regard to dynamic content (jsps, servlets, etc., ...) performance will swing widely depending on what the code is doing. Connecting to databases and other services are among the most expensive processes followed by hashing through large linear data structures. Also consider the amount of memory being used per session and per request against the size of the server. Lastly, developers always have to pay attention to taking care of their data structures and dropping references on them as soon as they aren't needed any more to avoid leaks. Bottom line -- the only way to tell how many users will be supported by a specific webapp/server combo is to stress test with an tool like JMeter. --David Martin Gainty wrote: Tim makes a very good point to make this distinction clearer there are 2 distinct concepts which we need to have clear understanding 1)there may be thousands of of (browser users) connecting in (on unix as the nobody account) to a tomcat server 2)number of users which are configured under $TOMCAT_HOME/conf/tomcat-users.xml which would be configured as something like user username=tomcat password=tomcat roles=tomcat/ in the latter case the number of users would be confined to number of maxThreads for the connector used On a side note It is a welcome respite to hear from courteous and polite professionals..if only for one day!

Any modern server can easily handle thousands of concurrent users. But that doesn't answer concurrent requests. Which should be 100/sec. But there are 2 major factors - use of HttpSession is light - Using HttpSession for users can kill scalability due to memory constraints. (YMMV) - Amount of work each request takes - images/css will be served very quickly as compared to JSP's or servlets which utilize database connectivity or file access. -Tim Li Ma wrote: Thanks for the suggestions.

Re: Tomcat on Gentoo from the horse, no hear say.
Despite your request to the contrary, this very long winded message is begging for responses. If all you wanted was for people with Gentoo packaged tomcat to contact Gentoo user's list, you should have simply requested that. On to the comments --- 1. Compiling tomcat. Why??? Java by it's design is one binary byte-code for all platforms. Is there really any reason to build it from source? Well... aside from the Commons-daemon code (jsvc) used to launch tomcat as a service and the tc-native library for the connectors. Those bits of native code still requires a build. 2. The tomcat-dbcp.jar is intended to avoid a classloader collision between tomcat's built-in database pooling functions and Commons-DBCP release builds. I don't see a problem here. 3. Personally I would create one package with tomcat-core as close as possible to what's provided by the tomcat download site and then create packages for all these dependencies. People can opt-in or opt-out of the extra features at their discretion. It would make more of the already built documentation applicable to their setup. Lastly, since the main point of this message is to ask us to steer Gentoo users towards you for questions, we would welcome a representative on the tomcat-users list who could respond to those questions. There shouldn't be a need to make people choose one or the other and most will seek out what they perceive to be the most authoritative source. I see if I google for 'Gentoo tomcat' I get your Tomcat guide as the first result. Too bad google isn't used more often for some of these questions. --David William L. Thomson Jr. wrote: Ok, not even sure where to start so I will kinda just jump in with this. I am not looking to start a flame war, or long thread. I would prefer this thread not to grow beyond this post. As there are better places, like Gentoo java mailing list, gentoo forums, irc, etc. In the Gentoo Tomcat Guide[1] I request users do this before say contacting upstream mailing lists or etc. Like what happened in this case. I am the present maintainer of Tomcat on Gentoo. I started doing so a year ago when I noticed 5.0.27 was the lastest stable, and 5.5.x was pretty far from hitting the tree, despite being almost a year old at the time. The Tomcat maintainer was mia. So I slowly took over and eventually became an official dev. To being with, on Gentoo we compile Open Source Software from source. This is quite common in the FOSS world everywhere except for Java.[2] For some reason you can't get Apache http server binaries, but you can get Tomcat binaries. With that said, compiling Tomcat from source is COMPLETELY different than downloading a pre-built binary version of Tomcat. That has bundled dependencies. As in third party jars not part of Tomcat, but shipped with it. Because Tomcat needs them to run. Now keep in mind not only are we compiling Tomcat from source, we are compiling all of Tomcat's dependencies from source as well. Which leads to considerable dependencies. So package A depends only on B, but to build package B might need/depend on the entire alphabet :) Tomcat 5.5.20, has a ton of build time dependencies with even more optional dependencies. It's not clear if the optional dependencies activate functionality or not within Tomcat. Some of these in question are like Sun's jaf and javamail. Which till recent were not open source or easily available, and could only be obtained as binaries from Sun. So instead of having a potentially limited functionality Tomcat, we provide all possible dependencies, as would be present when Tomcat devs build and package Tomcat. Others can't be bi-passed at all. Try compiling Tomcat with say IBM JDK. You will notice classes are missing. Because only Sun JDK's and blackdown implement JSSE. There is talk of removing that SSL code, and pretty sure has been done with Tomcat 6.0.x. We don't even package JSSE on Gentoo, since it's a pre 1.4 tech. Tomcat is one of the only apps that is using or needs that stuff. Now Tomcat 6.0.x has WAY less deps. A MUCH cleaner and clearer build/compile process. Despite a bit of nastiness still going on. Like naming-factory-dbcp.jar called tomcat-dbcp.jar. Is basically a slightly modified re-packaged and compiled from source commons-dbcp, commons-pool, and commons-collections. Most all Tomcat packagers for Linux distros have voiced their opinion on how that jar is built. So far seem to have fallen on deaf ears. Finally let me apologize for that unfortunately user who decided to post here first. Rather than contacting the proper channels first. Seems there is lots they don't get about the distro they have chosen to run. Much less where to go with questions, problems, or for help with distro provided packages. 1. http://www.gentoo.org/proj/en/java/tomcat-guide.xml 2. http://www.gentoo.org/proj/en/java/why-build-from-source.xml P.S.

Re: Re-executing a servlet request
You won't be able to re-compose the request object as if it was just
submitted. The quickest, dirtiest way is to just stow the form params
in the session upfront and then use them from the session later.
Example:
c:if test=${not empty param.mySubmitBtn}
c:set var=mySessProp scope=session value=${param.myFormField} /
c:set var=mySessProp2 scope=session value=${param.myFormField2} /
!-- Keep going though all the form fields you want to save. --

Re: File not found with file include in a jsp file.
No, no, no... Try this directory structure, starting with the appbase you declared in your host definition: wwwroot ROOT headerCon.jsp product product_view.jsp WEB-INF web.xml The web.xml can be very minimal -- just a web-app root element with the appropriate dtd or schema declaration. Then request http://localhost:8080/product/product_view.jsp. Note all the jsp files are contained inside the ROOT webapp folder. You name the ROOT folder something else, but be aware the ROOT name is special under tomcat and receives requests that don't match up with any other webapp. I would highly recommend you read the servlet spec at http://jcp.org/aboutJava/communityprocess/final/jsr154/index.html --David David Smith 写道: You can't have files in the webapps top level.

Re: [tomcat 5.0] - DBCP pooling vs sharing a single open connection
Single connections create bottlenecks and slow down throughput when the site get's busy. DBCP allows for multiple managed connections for faster performance. Plus it can take care of when connections die and create new ones automatically. There are shades of grey as well. I have one solution that made use of commons-pool (the pool component of DBCP). The app manages a pool of workers, each with a set of prepared statements ready to go. It boosted performance on the app a lot over the original single connection design. --David Ran wrote: Hi all, How does DBCP compare to application managed, single connection which stays open to share ?

Re: jsp optimization for db driver load and connection
You'll have to do something because the below code is very inefficient. Creating and closing connections is an extremely expensive operation and the way this is written you're getting one on every request. At minimum, I would recommend a ServletContextListener that creates a pooled DataSource, stored in the application scope. Then convert your code below to get the DataSource from there whenever it needs it. The difference will be day and night. Oh, yes ... and make sure you always close the connections as soon as you can after you're finished using them -- preferably in a finally block. --David IT Desk wrote: This isn't Tomcat specific but general to any jsp container and its jvm.

On each query, the statements are these: Driver DriverDB = (Driver)Class.forName(db_DRIVER).newInstance(); Connection ConnDB = DriverManager.getConnection(db_STRING,db_USERNAME,db_PASSWORD); PreparedStatement StatementDB = ConnDB.prepareStatement(SELECT * from table); ResultSet resultDB = StatementDB.executeQuery(); My 2 questions are: Does the forName call to load the driver get optimized out? Clearly the driver need only load once. Does the getConnection reuse the same connection that was done in the previous call on the same jsp page? There are some performance problems and I'm wondering if I should try to clean the code up or if the jvm does it for me through optimization. It's running on Tomcat 5.5.20 and JVM 5.x. The client won't pay for any major redesign so I'm looking for something small that could make a big impact. Thanks for any insight.

This sounds like an environment variable is changed during start or stop and the new value is bad. Your start and stop scripts aren't attempting to set classpath or something evil like that are they? Can't be that specifically, since the CLASSPATH environment variable isn't used by the JVM proper, just the launcher in the absence of the -cp parameter. Probably not any other environment variables, since (AFAIK) Tomcat's classloaders don't look at any. However, it might be interesting to compare the system properties visible to Tomcat after a reboot with those after a Tomcat restart. The LambdaProbe add-on can display them, for example. Turning on -verbose:class might also provide some hints, but it will produce a lot of output. - Chuck I'd agree in 99.999% of all cases, but there is always that 0.001% case to really throw a monkey wrench in the works. And I think we are looking at it. It might be worthwhile for testing to simply add some echo statements to the start and stop scripts to see what the environment looks at those moments. --David - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Connector question
Nope. You can remove the one not used. I would recommend you comment it out first and test. Remove when it's tested to work just to make sure you are removing the right one. --David Narayanaswamy, Mohan wrote: In one of my development server, we have the following two entry, Do we need both of the below entries to support Apache + Tomcat4.1.x? !-- Define an AJP 1.3 Connector on port 8009 -- Connector className=org.apache.ajp.tomcat4.Ajp13Connector port=8009 minProcessors=50 maxProcessors=800 enableLookups=false acceptCount=10 debug=0/ !-- Define a Coyote/JK2 AJP 1.3 Connector on port 8010 -- Connector className=org.apache.coyote.tomcat4.CoyoteConnector port=8010 minProcessors=50 maxProcessors=800 enableLookups=false redirectPort=8443 acceptCount=10 debug=0 connectionTimeout=2 useURIValidationHack=false protocolHandlerClassName=org.apache.jk.server.JkCoyoteHandler/ --- In http://tomcat.apache.org/tomcat-4.1-doc/config/connectors.html - org.apache.coyote.tomcat4.CoyoteConnector has mentioned as HTTP connector for modern browser, but when I send request to port 8010, I did not get any valid output on my browser.

Re: virtual mapping on Tomcat 5.5
1. the path attribute of your context definition will be ignored by tomcat 5.5. The webapp itself will be deployed as RMS, not images. 2. Assuming you have an images folder in your RMS webapp and a file named logo.gif exists there, the url http://localhost:8080/RMS/images/logo.gif should work. Check the logs if it's not working. 3. Please don't hijack threads.
