Where should I store my static content in a clustered environment
Hi, lets start with describing my current task where I would appreciate any advice from you. I have to construct a clustered system (with lots of webservers) that has few dynamic pages but a lot of static ones, whereby all resources have to be protected by security-constraints of a webapp (so letting Apache deliver this content won't work). Moreover there should be the possibility to upload/delete static components via a web form. My main problem is now where should I store the static data (mainly html pages, images, ...; but over 4 GB(!) large in total)? As far as now I'm considering the following solutions: 1.) Storing the content within the webapp of each webserver. This would include that the servers know each other as the upload/delete operations must be propagated from one server to all the others. Moreover the update of the dynamic parts would not be as easy any more as just uploading a new war-file as this requires deleting the old webapp directory (that contains the content is this case as well). 2.) Storing the content in a separate directory but still on each webserver. This would still include that servers must know each other, but updating the dynamic part would be easier. The downside is that I would have to write a servlet that delivers all static content with all the problems of mime-types, character encoding and so on which I would have to handle myself. 3.) Storing the content in a database on a separate server. The advantage would be that webservers only need to know their database server and updating the webapps would be easy (just uploading new war-files). The downside here is that I need a servlet too and I think it's maybe not the fastest solution as all requests of all servers to each single chuck of static content would require a connection to the database server. 4.) As 3.) but storing data on a single separate server in the filesystem. The advantages/disadvantages should be similar to 3.) whereby I do not know which solution might be faster. 5.) As 3.)/4.) but additionally implementing a caching-mechanism on the webservers. This means if a webserver gets a request for a specific page for the first time he connects the database server to retrieve that page, then stores it in its webapp directory and then let tomcat deliver that page. On the second request it is just checked if that page is already there and if so it is delivered directly. Of course I must implement some mechanism such that the webservers get to know if their cached data is outdated but so far this seems to me the best solution. Anyone ever faced this kind of problem? Any kind of remark to my possible solutions or any other possibilities you might know of are appreciated. Thanks you in advance for your help.

Vedr.: Where should I store my static content in a clustered environment
Hi Eickvonder, I would definitely go for solution 5, which resembles an assigment we were given in a course in Distributed Computing. If possible go for active replication to distribute the load on several database servers. To implement this you must implement a common frontend (FE) communicating with the replica managers (RM). A read operation simply connects to the FE which (using round-robin or similar) connects to a database server. If youre not worried about byzantine errors simply fetch the first file being returned. A write operation connects to the FE which updates all database servers. If you settle for this solution but something seems a bit unclear I recommend reading up upon distributed computing terms (e.g. "Distributed Systems: Concepts and Design", G. Coulouris, J. Dollimore, T. Kindberg, Addison-Wesley, 4rd edition, 2005, ISBN 0321263545) As far as invalidation goes you can basically choose timestamp cache invalidation or callback cache invalidation. Timestamp cache invalidation will upon each read request read the last time the file was updated and if e.g. 5 minutes has passed read a new file from the database. This is rather simple but does not ensure consistency. Further if the html files really are "static" and not changed very often you will probably choose long timeouts to minimize the number of irrelevant reads thus prolonging the time the webservers are out of sync after an update has been comitted. If possible memorywise save the state (fileId as int, time as long) in a hashmap or similar on the webservers to avoid having to read from disk before determining whether to fetch from the database. Callback cache invalidation is better at acheiving consistency and minimizes reads from the database. The FE/RM should know which webservers has requested which files and send an "invalidate" to the those webservers when a client commits an update (thus ensuring webservers which have read the file will read it again once it is requested from a client). Also if possible here memorywise save the state (webserverId as int, fileId as int, time as long) in a hashmap or similar on the webservers to avoid having to read from disk before determining which webservers to invalidate.

Ah. Unzip it into the same folder into which you've installed Tomcat.

Content is not allowed in prolog Tomcat-XmlRpc

If in method doPost()I call request.getInputStream, I can see header lines. I'm using Apache XmlRpc, so the body is a xml document, when I try to parse this body, I get a "Content is not allowed in prolog" error, because the parser finds this header lines in the body (document to be parsed). It's very strange, we only get this error when we use a xmlrpc client written in C and using xmlrpc-c and libwww. Has anybody ever seen a similar problem. Any kind of help would be very appreciated.

RE: ordering apps startups
This one has been addressed several times before. The short answer is NO. Tomcat being multithreaded does not guarantee order of start or access of a page.

Tomcat doesn't load classes
Hi, i'm having a strange problem to load classes from the directory WEB-INF/classes. I placed an url.properties file there, restarted Tomcat (version 5.0.28), but the classes aren't loaded as far as i can see. I've tryed to store the file on other locations (ROOT/, webapps/ etc), even in the $CATALINA_BASE/shared/classes, but no luck at all... Ofcourse i read http://tomcat.apache.org/tomcat-5.0-doc/class-loader-howto.html, tryed Google etc, but i still couldn't find a solution to my problem. I also cannot find anything in the Tomcat logfiles... This is the content of my url.properties: # Basic pages ADMIN_LOGIN_URL = /admin/jsp/login.jsp ADMIN_HOME_URL = /admin/jsp/home.jsp ADMIN_WEBSITE_HOME_URL = /admin/jsp/website.jsp # List pages ADMIN_USER_LIST = /admin/user/userList.jsp ADMIN_THEMA_LIST= /admin/thema/themaList.jsp ADMIN_STYLE_LIST= /admin/style/styleList.jsp ADMIN_TEMPLATE_LIST = /admin/template/templateList.jsp ADMIN_MODULE_LIST = /admin/module/moduleList.jsp ADMIN_NEWS_LIST = /admin/news/newsList.jsp # Edit pages ADMIN_USER_EDIT = /admin/user/userEdit.jsp ADMIN_THEMA_EDIT= /admin/thema/themaEdit.jsp ADMIN_STYLE_EDIT= /admin/style/styleEdit.jsp ADMIN_TEMPLATE_EDIT = /admin/template/templateEdit.jsp ADMIN_MODULE_EDIT = /admin/module/moduleEdit.jsp ADMIN_NEWS_EDIT = /admin/news/newsEdit.jsp # Data actions DATA_ACTION_FIND= 1; DATA_ACTION_CREATE_NEW = 2; DATA_ACTION_SAVE_CURRENT= 3; DATA_ACTION_UPDATE_CURRENT = 4; DATA_ACTION_DELETE_CURRENT = 5; DATA_ACTION_COPY_CURRENT= 6; DATA_ACTION_EDIT= 7; - I guess i do something wrong, but i cannot find what Thx for help!
Re: ordering apps startups
Rogiero If this is an option for you I would use JBoss to manage the deployment ordering. You have implicit and explicit behavior. For example the deployment ordering scheme could be the you name your war: 01appA.war, 02appB.war Here the apps will be implicitly loaded in this order. This is know as the deploymentSorter implicit policy. Its policy is defined in the conf/jboss-service.xml by the attribute URLComparator set to DeploymentSorter or PrefixDeploymentSorter. There isa very good adminguide on jboss wiki. I suggest you have a look at it. Hope this helps.

RE: Where should I store my static content in a clustered environment
A simple solution would be to have all static pages hosted on an Apache httpd server in front of tomcat clusters. If you need more performance, just cluster the httpds. Tomcat is not really designed to server static pages. Apache httpd can also serve as a LB. In this case, certainly you have to treat static pages separately from dynamic webapps. In other words, you can't bundle static pages with your war files.

I have to construct a clustered system (with lots of webservers) that has few dynamic pages but a lot of static ones, whereby all resources have to be protected by security-constraints of a webapp (so letting Apache deliver this content won't work).

My main problem is now where should I store the static data (mainly html pages, images, ...; but over 4 GB(!) large in total)? As far as now I'm considering the following solutions: 1.) Storing the content within the webapp of each webserver. This would include that the servers know each other as the upload/delete operations must be propagated from one server to all the others. Moreover the update of the dynamic parts would not be as easy any more as just uploading a new war-file as this requires deleting the old webapp directory (that contains the content is this case as well). 2.) Storing the content in a separate directory but still on each webserver. This would still include that servers must know each other, but updating the dynamic part would be easier. The downside is that I would have to write a servlet that delivers all static content with all the problems of mime-types, character encoding and so on which I would have to handle myself. 3.)

It appears that, at least with IE on XP, Acrobat Reader stays loaded as long as the browser is active. Consequently, a new process is not started with each download; all that happens is a new document window is opened by the already active .

JAASRealm-based Login Fails After Upgrade from 5.0 to 5.5
I have a stable, working, Struts-based web application running under Tomcat 5.0.28 that uses HTTP BASIC authentication and a JAASRealm (with a home grown LoginModule and user and role principals) over SSL. The authentication / security has been working with no issues for several releases. I am now trying to upgrade Tomcat from 5.0.28 to 5.5.12. I've rebuilt the web application using JDK 1.5.0_05. I've followed the usual procedure for installing and configuring Tomcat, including modifying server.xml to remove the deprecated references to Logger. My web application appears to start with no problems according to the various log files. I then browse to it. I receive the SSL certificate as usual and the browser requests that I login in (via its pop-up box) - again as usual. I do so. According to my web application logs, the correct LoginModule is activated and I login successfully and the appropriate roles are assigned to the user. However, rather than taking me to the home page of the web application I am redirected to the 403 (permission denied) error page - which displays with the correct images and style sheet. I've search the FAQ, bug lists, mailing lists and the web, but have been unable to find any directly relevant help. Any thoughts? In particular has this area of Tomcat changed? My understanding is that the servlet and JSP specs are the same for Tomcat 5.0 and 5.5, so I should expect the same behaviour. Relevant snippets from "server.xml" and "web.xml" are below. Thanks, David Snippet of server.xml ...

Yes, since you don't have a configuration in your web application
(WEB-INF/classes/logging.properties), everything uses the
configuration of the container and it all depends on the logger names
used.
Note: you should be able to capture and log System.out stuff to the
container logger using swallowOutput

As far as I can tell, network drive mappings are not visible to a service, even when the service is run under an account that has persistent network connections. By using the .bat files to run 5.5.x, you should be able to do what you want. Note that the .bat files are only included in the .zip Tomcat download, not the .exe one (seems silly, but that's the way it is). - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
