If the directory listing is set to false, and if there is no index.jsp file under the web application's root folder then you'll see a 404 HTTP status.

If they are then it would be a good idea to keep all JAR files in a common location. The JAR files don't have to be /tomcat/common/lib , they can be anywhere else -- as long as your ant build script has the path of the dependency JAR files. I would keep all dependency JAR files in any common folder outside Tomcat. or should I keep them in their individual war file structures? If the projects are not closely related and each of them evolve in their own direction then keeping the JAR files in individual WARs would be beneficial in terms of ease of maintainence. I understand how moving the stuff into /common/lib means everything uses the save version, but what is best for performance? Thanks!

Re: Tomcat URL decoding different from Java's URLDecoder?
Shankar, Chris, With reference to your previous posts (From section 3.7.1 of the HTTP/1.1 spec). I tried a small example by not forcing the request's content type, and was able to see the Big5 characters without any problems even when the Request's characterEncoding was null. The code below demonstrates this. So Tomcat is running with -Dfile.charset=Big5 (so that's the java default charset), and just does a 'request.getParameter(foo)'. And the value for foo in the body of the POST is %AEx, which (again) we didn't encode - it's IE that's doing this when you type in a Big5 char into a text field in a form (I guess it's internally treating the raw bytes as ISO8859-1). %AEx , could be a URL Encoded Hex representation of the specific Big5 character (not sure about it though, because decoding it doesn't give a Big5 character but instead gives garbage characters) Here's the example I tried, that shows the Big5 character correctly when transmitted over HTTP GET , notice the characters in the URL encoded parameter. - index.jsp - %@ page pageEncoding=Big5 contentType=text/html; charset=Big5 % html head meta http-equiv=Content-Type content=text/html; charset=Big5 / /head body % //String paramEncoding = application.getInitParameter(PARAMETER_ENCODING); //request.setCharacterEncoding(paramEncoding); % Request Character Encoding = %=request.getCharacterEncoding()% br/br/ Response Character Encoding = %=response.getCharacterEncoding()% br/br/ form action=test.jsp method=GET input type=text name=textField value=造字/ input type=submit name=submit value=submit/ /form /body /html -- test.jsp -- %@ page import=java.net.URLDecoder % %@ page import=java.net.URLEncoder % %@ page pageEncoding=Big5 contentType=text/html; charset=Big5 % html head meta http-equiv=Content-Type content=text/html; charset=Big5 / /head body % //String paramEncoding = application.getInitParameter(PARAMETER_ENCODING); //request.setCharacterEncoding(paramEncoding); % Request Character Encoding = %=request.getCharacterEncoding()% br/br/ Response Character Encoding = %=response.getCharacterEncoding()% br/br/ Text Filed Contents = %=request.getParameter(textField)% br/br/ URL Encode: %=URLEncoder.encode(造字, Big5)% br/br/ URL Decode: %=URLDecoder.decode(%B3y%A6r, Big5)% The above shows garbage characters. /body /html --- web.xml --- context-param param-namePARAMETER_ENCODING/param-name param-valueBig5/param-value /context-param --- Tomcat 6.x server.xml Connector port=9090 protocol=HTTP/1.1 maxThreads=150 connectionTimeout=2 redirectPort=8443 URIEncoding=Big5/ -Rashmi - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

String paramEncoding = application.getInitParameter(PARAMETER_ENCODING); request.setCharacterEncoding(paramEncoding); Now Java's URLDecoder.decode(s, Big5) doesn't like the above encoding: it insists that both characters be encoded, or neither - it ends up decoding this into ?x.

Since the above is a ~page relative~ path, both test.jsp and error.jsp should be in the same folder , otherwis error.jsp will not be found. A better approach would be to make errorPage a ~context~ relative path , something like errorPage=/errors/error.jsp , this way error.jsp will be visible to any page in your app when you use that path. 2) Is the web.xml configured correctly, is the path of error.jsp in web.xml correct?

Pre-compiling JSPs does take a while because, first JSPs are converted to .java files , then the .java files are compiled to .class files, and then the web.xml is modified. Most people reserve pre-compiling JSPs to just before the app is ready for deployment into production environment. Pre-compiling for development, staging and other environments would take too much time and effort unnecessarily. I'm surprised that your script needs those package rename hacks.

It depends on how you set up your Ant build to use Jasper. In any case, the original web.xml gets modified , the original mappings etc will be retained, the new JSP class mappings will be ~appended~ , so you won't lose anything that was already there. If you don't want your original web.xml to be modified, using Ant you can make an intermediate copy of your project, and run Jasper on that intermediate copy, this way the web.xml of the source files will not change - which is ideal for development environment settings. Try it on a separate, small project to see how it works and what works for you.

Otherwise the webapp itself will supply a Context. Tomcat will generate a Context on its own in some circumstances which I've not yet completely worked out from the documentation. How did you disable this? In the development environment settings, I don't usually add a context.xml file under META-INF. I normally create a ContextName.xml file under each Host Name folder. So with the above setting, I can visibly see in Tomcat's start-up console that it has loaded only those webapps that have a .xml file, and doesn't load those that don't. I also keep my projects ~outside~ Tomcat's webapps folder and I only specify the project's root folder in the docBase attribute of Context. The appBase attribute is something like webapps/ContextName , and path is empty. This way, upgrading Tomcat becomes easier and simpler. I haven't really experienced Tomcat generating a Context (either in server.xml or a Context xml file under Host Name ) May be it generates one under META-INF/context.xml , but may be empty as in Context path= /Context -- Mark H.

Re: Excluding JSP compiler from Tomcat
On 5/25/07, lightbulb432 [EMAIL PROTECTED] wrote: The JSP spec says that if you precompile JSPs you can reduce the JSP container footprint by excluding the JSP compiler. How can this be done in Tomcat? I know of 2 ways to pre-compile JSPs 1) http://tomcat.apache.org/tomcat-4.1-doc/jasper-howto.html If you're using Ant , than you can add the above jasper task to your build process. The process first converts all JSPs to .java files, and then all .java files are compiled to .class files , during this process the web.xml is also auto-modified and there's an entry for every JSP page in your app. Pre-compiling with jasper is very slow (expected behavior) , so it is recommended that the pre-compile should be done just before deploying the app to production , there's no need to pre-compile while developing/ testing JSPs. 2) Use JSP Unit testing tools like HttpUnit or Apache Cactus, as the tools test each JSP page they acces the JSP pages for the ~first time~ , this essentially compiles all JSP pages , then move the war file to production. Many recommend the 2nd option as it makes your pre-compiled code portable aross containers. Thanks.

Say your apps are named app1, app2, app3 etc and if you access them as http://localhost:8080/app1 http://localhost:8080/app2 http://localhost:8080/app3 , then you would define the Context for each app under Tomcat's /conf/Catalina/localhost/ as app1.xml , app2.xml and app3.xml Now if you want Tomcat to only load app1 , you just disable the other XML files by renaming them as in app2.xml_disable app3.xml_something The above setting will make only app1 visible to Tomcat, when you want to switch, just rename the Context file back to .xml Alternatively , if you want all apps to be accessible at the root context, you just set up virtual hosts, in this case each context would be called ROOT.xml under it's own host, just disable the ROOT.xml files of those apps you don't want to load. This way I can simply Start the few apps I need via the Manager and as I need more or less, I can do so. However, it is not possible to use the Manager app to toggle the Context XML files' extension, you'd be toggling the extension manually.

If any of the entity tags match the entity tag of the entity that would have been returned in the response to a similar GET request (without the If-None-Match header) on that resource, or if * is given and any current entity exists for that resource, then the server MUST NOT perform the requested method, unless required to do so because the resource's modification date fails to match that supplied in an If-Modified-Since header field in the request. Instead, if the request method was GET or HEAD, the server SHOULD respond with a 304 (Not Modified) response, including the cache- related header fields (particularly ETag) of one of the entities that matched. For all other request methods, the server MUST respond with a status of 412 (Precondition Failed). And the definition of ETag : http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.19 mentions entity-tag , which is also the value of a few other caching tags: If-Match If-None-Match Vary The value of the above tags returns the same checksum for the static resource as the ETag does.

I did notice the ETag for static files on one website that is hosted on Apache httpd + Tomcat. Is there a reason that the Etag is not being included? Is there a way to configure Tomcat to include this? My company is working with a caching solution provider, and they are complaining about the missing ETag. thanks.

Re: Tomcat 6 trimDirectiveWhitespaces
You're welcome. It may be a good idea to file a bug, because Tomcat 6.0.10 supports JSP 2.1 and trimDirectiveWhitespaces is a new feature in JSP 2.1 , it is supposed to work. I've personally tried Ant's RegEx to compress the white spaces in HTML, JS and other files, I've also heard that it is pointless to compress white spaces because files sent by the server are gzip compressed anyway --- which takes care of the white spaces, and then they are uncompressed on the browser --- which makes the white spaces appear again. There are some things you should watch out when white space compressing with Ant's RegEx. It puts everything in one single line. So if you've used open comments such as // in either JSP or JavaScript, the code after // will be commented out. Similarly if you omit the closing semicolon in JavaScript, and everything falls on one line, the Javascript wont work as expected. The solutions are not to use open style comments // and to close all Javascript statements with a semi colon. Anyway, your situation may be different but I just thought I'll let you know. -Regards Rashmi On 5/14/07, Milanez, Marcus [EMAIL PROTECTED] wrote: Thanks for your attention!

Please let me know how to achieve it. There are different configurations possible, the list of configurations I'm writing here is just to give a hint and may not be complete and may be partially correct but it gives the desired behavior. 1) One configuration is back up the default ROOT folder that ships with Tomcat and then rename myAppname.war to ROOT.war , then you can access the app at http://localhost:8080/ --- the root Context. 2) Another configuration is: In development environment , remove the myAppname.war and delete the myAppname folder from the webapps folder --- assuming you backed this up somewhere. Also delete ROOT.war and ROOT folder under webapps folder. Then simply create a ROOT.xml (Context file) under Tomcat's /conf/Catalina/localhost/ folder , define the Context node in this ROOT.xml , for example: Context docBase=C:/dev/projects/myAppProject / With the above configuration also you can access your application at http://localhost:8080/ 3) Other configurations are also possible, but the above are what I know as of now.

Then, when I make any changes to the static content, I just have to rebuild and redeploy .war files for each webapp I'm running. There would be multiple copies of sidebar.html and images, etc. on the server, but that wouldn't matter as I would never edit them directly. This seems like a good compromise - any thoughts? It depends, if you have 10 different websites, then it would create 10 different copies. It may or may not become a maintenance nightmare in the future.

Re: Redirecting URL request to Tomcat to folder containing Cruise Control
However, from the subject of your e-mail it appears that you want to do a Redirect from http://localhost:8080/standard/ to http://localhost:8080/cruisecontrol/ which is easy to accomplish. within a JSP Scriptlet: %response.sendRedirect(/cruisecontrol/); % with JSP/JSTL c:redirect tag within a Servlet: response.sendRedirect(/cruisecontrol/); The above redirects with HTTP 302 I guess thats what you're looking for.

Re: JAR file not finding external properties files
Hi Mike,
On 5/1/07, Mike Peremsky [EMAIL PROTECTED] wrote:
What do I need to do to get the class in the jar file to find the properties
files external to it?
To access a properties file that is external to the JAR file , add the
full path of the Properties file's folder to the CLASSPATH.
If you add the path of the Properties file to the CLASSPATH, there's
no need to place the properties file under /WEB-INF/classes/ folder ,
it can be located anywhere you want.
After setting the CLASSPATH, the properties file can be accessed
simply by specifying its name.
For example:
If the mypropertiesfile.properties is placed under
C:/dev/mypropertiesfile.properties
set CLASSPATH=%CLASSPATH%;C:/dev/
public class TestPropertiesFile {
public static void main(String[] args) {
ResourceBundle props = ResourceBundle.getBundle(mypropertiesfile);
//String planet = (String) props.getObject(planet);
//System.out.println(Planet: + planet);
}
}

Re: Context started twice
I tested your code, the init is called exactly once, when Tomcat starts.
Try one of these:
1) Change
log.info(TestServlet init);
log.info(TestServlet destroy);
to something else like
log.info(TestServlet init ## );
log.info(TestServlet destroy ##);
Re-compile, re-start TC if necessary and
check if you see 2 different outputs on the console.
2) If you see the same output twice, that is if you see
log.info(TestServlet init ## );
log.info(TestServlet init ## );
log.info(TestServlet destroy ##);
log.info(TestServlet destroy ##);
then check web.xml if the same Servlet is defined twice under
different names.
3) Globally search for TestServlet init and see if it appears in
more than one Servlet that may be visible to the current installation
of Tomcat.

Re: How to share static content across multiple tomcat webapps
Hi Martin, On 4/30/07, Martin Jones [EMAIL PROTECTED] wrote: Hi, This seems like an obvious question but I'd appreciate any answers. I have several webapps running under tomcat that need to be able to include the same sidebar in their .jps. if the sidebar is within the context, this works fine: %@ include file=sidebar.html % However this requires me to keep a copy of sidebar.html (and all the images) in each .war. I'd rather keep a single copy of sidebar.html. If I make a new context static in tomcat and place the sidebar + images there, I can access it fine in my browser with the url: http://localhost:8080/static/sidebar.html but the naive change to the jsp: %@ include file=../static/sidebar.html % The include directive is out of the question because according to it's syntax http://java.sun.com/products/jsp/syntax/2.0/syntaxref209.html#1003408 it only accepts URLs that are relative to the web application (a.k.a Context). fails with the path specifies a resource outside the web application. Using jstl and import: c:import url=../static/sidebar.html/ JSTL's c:import tag has an attribute called context, http://java.sun.com/products/jsp/jstl/1.1/docs/tlddocs/c/import.html which allows one to access resources from other contexts (a.k.a web applications) , however in order to function properly the crossContext attribute of the web application's Context node must be enabled (set to true). From my experience setting crossContext to true has caused other conflicts when 2 resources (Java Classes) have the same name in 2 different web applications that have crossContext enabled it could be that there was something wrong in my configuration. But, I'm just letting you know about it. leads to: javax.servlet.jsp.JspTagException: /../static/sidebar.html However, if I use the absolute path: c:import url=http://localhost:8080/static/sidebar.html/ the page is fine, but because the paths to the images are copied directly from sidebar.html and included in the .jsp they are incorrect. In this case you would also need to change the URLs of the images to be the absolute URL. It seems to me that what I'm trying to accomplish is a fairly common thing; I'd appreciate any pointers. Normally it is considered bad practice to hardcode the entire URL, you may want to store the domain etc in a constant and prefix it to the rest of the URL. Also, there might be better ways to accomplish this. I don't know much about JNDI but it comes to mind, is it possible to store images as a global JNDI resource.

Could you elaborate on what you meant by sessions not working when the browser caches a page? If a user submits a form in a cached page, wouldn't they still be directed to their same session on the server? (Whether the session ID is stored in URL, cookie, or hidden form field.) If the session id is stored in the URL, cookie or hidden field it may be possible to access the session, if the page is cached by the browser but I haven't tested it. From my experience with sessions , the functionality implemented with sessions stops working as soon as the page is cached by the browser.

Re: unexpected session behavior in Tomcat 5.x
On 4/28/07, David [EMAIL PROTECTED] wrote: I'm hoping someone can shed light on some session anomalies I'm seeing with Tomcat 5.0.2.8 and Tomcat 5.5.23. I have a web application containing FacesServlet ( javax.faces.webapp.FacesServlet) as well as some additional servlets that also make use of the Faces Context. The normal flow is: 1) call into the FacesServlet for some work, 2) invoke another servlet, ServletA, via doPost. Within doPost images are generated dynamically and the bytes are stored within a session. 3) The response returns 1 or more URLs each of which will call back ServletA via doGet to have the image data retrieved from the session and streamed back to the client. These URLs are created using the encodeURL method on the response to attach the session id. In one case step 1) does not require any session information to be created. So when step 2) occurs a new session is created, and in step 3) within doGet this session is correctly retrieved and things work beautifully. However in another use case step 1) requires some information to be stored in the session, so Session 1 is created. When step 2) occurs, another session, Session 2 is created. The fact that Session 1 is not reused is the first surprise. When encodeURL is used in step 2), Session2's id is encoded into the response URLs. However in step 3), when the servlet's doGet is called back, the session that is returned is Session 1 which of course does not have the image bytes. Of note, in step 3) the HttpServletRequest object reports that the session is coming from a cookie, not the URL. It could be possible that you configured Tomcat 5.0.2.8 and Tomcat 5.5.23 instances differently. If you set the cookies attribute for your web application's Context to true then the JSESIONID is stored in the browser as a cookie. If cookies is set to false then jsessionid appears in the rewritten URL. Reference: http://tomcat.apache.org/tomcat-5.5-doc/config/context.html Any thoughts on what might be going on here? My first thought is that this is a bug in Tomcat. Guidance on how to further debug this issue, or come up with a work-around is greatly appreciated.

The behavior I'm seeing is the same in both Tomcat 5.0 and 5.5, and they are both configured the same -- using default behavior for cookies. Sorry for repeating this, but just to be clear, in the above statement, default behavior means that cookies=true. This means that in the browser when cookies are enabled, JSESSION id will be written to a cookie. I should elaborate further and mention that the urlEncode method causes url rewriting to occur. So a cookie does not appear in my client browser (verified with a cookie viewer for IE). Despite this apparent lack of client side cookie, when doGet is invoked in step 3) Tomcat exposes a cookie object with the session id of Session1 off of the HttpServletRequest object What happens if you set cookies=false ? and has stripped off the Session 2 session id on the encoded URL from step 2).

Thanks for the info.
For my application, I am using Tapestry which uses
html templates which
I was having trouble to be reloaded by tomcat.
I don't know Tapestry, but when I write a normal JSP or HTML file, all
I have to do is press the browsers Refresh button, and I see the
latest changes I've made.
What I ended up doing was to write an ant hotdeploy
script to copy the
files to my tomcat installation then have ant invoke
the reload
command on tomcat.
Also, I keep my projects outside Tomcat's/ webapps folder and simply
configure the docBase attribute of the Context node to point my
project's folder and Tomcat finds it, when the {ApplicationName}.xml
or ROOT.xml containing the Context node is placed under
/conf/Catalina/[Host]/ folder.
The above set-up saves a lot of development effort and time because,
all that is required to see changes in JSP/Html is a browser refresh.

I've tried forcing the url rewriting behavior by deploying the following

This provides a work-around under Tomcat 5.5, but does not change the
behavior seen under Tomcat 5.0. And of course, Tomcat 5.0 is the version we
ship our product with. :) I've also tried taking the snippet and adding it
to Tomcat 5.0's server.xml file, but that also does not force url rewriting.
So there seem to be two issues. First, when url encoding produces cookies,
why does the request to the servlet in step 2) not transmit the cookie and
reuse the same original session, but it is sent and reused in step 3)?
I didn't see the behavior you're describing above when I conducted a small test.
What I see is that the exact same JSESSIONID is being passed between 3
different servlets, when URL Rewriting is used and cookies=false is
used. Also with this setting a cookie is not being written to the
browser at all.
Even when URL Rewriting is not used or when cookies=true , there is
exactly one JSESSIONID cookie in the browser.
I suspect that there might be something in the custom written code
that is probably invalidating the existing session, or removing the
attribute from the session or the session is timing out and a new one
is being created or the page is getting cached by the browser and
hence invalidating the session.
In my test case I set cookies=false in the definition of my
project's Context XML file and then I wrote the following 3 servlets:

FirstSessionServlet.java

The above test was conducted on the Tomcat version I have which is not 5.0. If you check your code throughly and the problem still occurs in 5.0, you may want to file a bug --- only if you're sure it's a bug --- otherwise it will not be resolved , if it's not a bug :-) -Regards Rashmi - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

What you do when you are looking up is just finding a reference to the pre-existing datasource. So don't worry Hi Ali, Thank you for the above post, I agree with it. Normally one has to write the following lines to get the database connection from the connection pool: Context initContext = new InitialContext(); //(1) Context envContext = (Context)initContext.lookup(java:/comp/env); //(2) DataSource ds = (DataSource)envContext.lookup(jdbc/TestDB); //(3) conn = ds.getConnection(); //(4) I think most people try to initialize the DataSource object in the above code, when Tomcat starts up and they only wan to get the ds object in a DAO class before creating a new connection from the connection pool. I think Srinivas wants to create the ds object when Tomcat starts up and re-use the ds object in the DAO class instead of re-creating it each time he needs it inside a DAO. and please do not write your own lifecycle :-) Regards, Ali. -Regards Rashmi - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Hi Rashmi,
I'm confused...so in tomcat 6.0 it reloads if it

Hi Josh,
reloadable is an attributed on the Context node of your web application.
The basic concept is that each web application corresponds to one
Context and is located under a Host.
So for your application there has to be a corresponding Context node
either in server.xml or as {ApplicaitonName}.xml file under
TomcatFolder/conf/[Engine]/[Host]/
Please locate the Context of your application (depending on where you
configured it), and add the attribute reloadable=true to it.
Re-start Tomcat just one time, after that whenever you re-compile your
classes or make changes to the JAR files under /WEB-INF/ , Tomcat will
automatically re-load.
It would be helpful to know which version of Tomcat you're using as
some attributes are not supported in certain older versions of Tomcat.
But for the sake of reference I assumed the latest version.
Hope this helps.

The basic doubt I had was whether the JNDI lookup would create a new data-source on each lookup or just return the previously created one. A number of you had said that the latter was true. The reason I wasn't sure about that was because I'm creating C3P0 ComboPooledDataSource objects using the BeanFactory factory. And the docs here state that each lookup creates a new bean, which in my case is a new data-source: http://tomcat.apache.org/tomcat-5.5-doc/jndi-resources-howto.html#Generic%20 JavaBean%20Resources I decided to test this by adding some logging in the various servlet init() methods to dump the C3P0 object returned from the lookup. The log output suggests that the same object is being returned back i.e. only one ComboPoolDataSource object is being used by both servlets. This is good for me. But it doesn't explain the discrepancy with the docs. Hi Srinivas, I don't see any discrepancy based on David's point in the above post: MyBean bean = (MyBean) envCtx.lookup(bean/MyBeanFactory); , doesn't create a new bean. FYI: I refer to this doc: http://tomcat.apache.org/tomcat-5.5-doc/jndi-datasource-examples-howto.html specifically for JDBC Connection pooling , instead of the above link you referenced as it closely concerns with JDBC and not general JNDI.
