enhydra
Greetings! I've been looking for a web host that provides JSP along with Beans. I came across one that mentioned it uses Enhydra. I've looked at the Enhydra web page and was left wondering if Enhydra is a replacement Servlet engine for Tomcat? Or, does it need Tomcat to run?

Re: enhydra
Enhydra uses Tomcat internally. the version of tomcat is very old, though. It depends on what version of Enhydra the ISP is using. If it is the open source one, then it is likely very old indeed. If it is the now defunct Lutris Enhydra EAS, then it would be something like Tomcat-3.2.x. There is a new project called Aonyx which will be Enhydra 5.0 when released. The current version is 5.0beta2. http://sourceforge.net/projects/webdocwf If you want to use Enhydra, that is your best bet since it is actually an active project. Not sure what version of Tomcat it uses internally, though. Jake At 09:47 AM 8/3/2002 +0200, you wrote: Greetings! I've been looking for a web host that provides JSP along with Beans.

Re: UserDir
I am no expert on tomcat but as far as I know the tomcat server needs to be restarted each time the contents of one of the web application source code files changes. If something like UserDir really can be set so that $CATALINA_HOME is different for every user, then there should probably be a cron job on the system to restart the server at regular time intervals or something like that.

I tested add this parameter to /etc/init.d/tomcat4 (= wrong parametr), to dtomcat4 (=no Class found), to tomcat4.conf (= nothing was generated).

Mona, I'm assuming you are running Tomcat 4.04 standalone, on :8080. Not quite sure exactly what the issue is here, but I have some suggestions: Just for fun, try a different browser to see if the problem is client side. Does the user Tomcat is installed as have permissions to read those directories '/scratch/project/telescience'?

Re: nullpointer (on forward) in tomcat (both 331 332)
Jeff,
The Javadocs for ServletContext.getRequestDispatcher( String pathname ):
The pathname must begin with a / and is interpreted as relative to the
current context root. Use getContext to obtain a RequestDispatcher for
resources in foreign contexts. This method returns null if the
ServletContext cannot return a RequestDispatcher.
Also, add a test here:
try {rd = sc.getRequestDispatcher(nextPage);
if( rd==null )
System.out.println( Rd is null. );
}
catch (NullPointerException np) {
System.out.println(* NullPointerException on
getRequestDispatcher );
np.printStackTrace();
}
Hope that helps...
Regards,
Michael

Re: how to deny directory listing
There are various ways to deny directory listing. Valid for both Tomcat 3.x and Tomcat 4.x.x: You could add a welcome file to your web.xml. Something like this: welcome-file-list welcome-fileindex.html/welcome-file /welcome-file-list See conf/web.xml for further information. Valid for Tomcat 3.x only: Look for the StaticInterceptor defn. in your server.xml. Set the supress property to true when no welcome file is present. Valid for Tomcat 4.x.x+: Edit the init-param listings for the default servlet. Change the param value to false.

The major conerns are: 1. Delegating to untrusted customers maintenance of their applications without compromising server security. 2. Configuring Apache and Tomcat for virtual hosting. 3. Surviving poorly written web applications installed by customers. This includes fault tolerance and identifying which customer's web application is causing problems. 4. Mimimize the amount of hand holding or config changes the apache and tomcat system administrators have to make. This is written based on my experiences setting up this type of hosting environment on Sun Solaris hardware. Some of this will be specific to Solaris, but in general should work for almost any flavor of Unix. Unix accounts and groups The user tomcat was created for running tomcat, it should be created similar to the nobody account used for running Apache. The tomcat user is assigned to the group tomcat. The tomcat user is a member of group user. The group tomcat was created as the group the user tomcat is assigned to. The group user was created, this is the group customer ftp accounts are assigned to. The tomcat account is a member of this group so that both customers and tomcat can write files in directories assigned to group user. Each customer has their own ftp account which is in group user. There is a webmaster administrator shell account. This account is for your virtual host administrator. The webmaster account is assigned to group user and is also a member of group tomcat. Directory layout The layout of directories is designed to make it as easy as possible for customers to maintain their own web space content and applications. Here is an example of how I do it: The customer is assigned an FTP account which has permission to read their virtual host directory and write to a subset of that. For example, a customer may be assigned the following directory: /export/home/www.customer.com root:other 755 Within that directory are sub directories which the customer can read and/or write. Listed are the directory names, ownership, and mode. www webmaster:user 2775 -- Apache document root directory. Customer and tomcat can both read/write directories and files. logs root:other 755 --- Directory where apache access_log and error_log are placed. We also rotate these logs weekly and use bzip2 to compress any log files older than 5 weeks. Log files less than 5 weeks old are left uncompressed so that they can be used by web statistic software like Analog. Customer can read files in this directory but not write files. tomcat tomcat:tomcat 755 Directory used for the tomcat work and tomcat virtual host logs. Only tomcat can write in this directory. Customer can read files in this directory. tomcat/work tomcat:tomcat 755 - Tomcat work directory for virtual host. Only tomcat can write files. Customer can read files. This allows customer to review java source files generated during a JSP

But my users should be able to define their own contexts for the tomcat. So my questions are: - how to configure the apache and tomcat to forward all JSP and servlet request from apache to tomcat. You could use mod_webapp or mod_jk. mod_jk gives you more control over what Apache forwards to Tomcat. mod_webapp will forward everything under a particular directory to Tomcat. With mod_jk you could direct Apache to forward requests with certain url patterns to Tomcat. Generally /servlet/ and *.jsp. - how should I setup tomcat to make it possible, that only a defined list of users are able to use jsp/servlet? If you are using Apache as the webserver, then you could do this easily by telling Apache to forward only certain requests to Tomcat. Using mod_jk as a connector would help in this case. - how to setup tomcat or must I setup the apache (if forwarding the servlet/jsp request from apache to tomcat), that users are able to define their own contexts? Is it a security problem? I thought about something like a distributed web.xml in a defined location in the users home dirs. Allowing users to create their own contexts, which amounts to modifying the server.xml file, isn't a good idea. You wouldn't want user stepping on each other's toes as well as violating the security of your system. I'd suggest you seek alternate methods. One way is to use the Listener class UserConfig. Assuming that every user has a home directory, Tomcat will be able to map a request starting with a ~ and a username to a directory, usually public_html, under the user's home directory. See http://jakarta.apache.org/tomcat/tomcat-4.0-doc/config/host.html for further details. I think with Tomcat 4.1.7, you can seperate the Context entries from the main server.xml file. I haven't used Tomcat 4.1.7. But I think you could define Contexts in some other file. And then add that file to the webapps directory. This way you could seperate Contexts for each user which probably gives you finer control. User's could define their own Contexts and then forward them to you to add the files to the webapps directory. - Is it possible to limit the maximum used resources (load, memory ) of tomcat? Or even better per user basis? I don't think you could limit the amount of resources on a per user basis. At the serer level, I guess you could specify the stack and heap size when Tomcat starts. many thanks, and best regards, Hans -- GMX - Die Kommunikationsplattform im Internet. http://www.gmx.net -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED] -- GMX - Die Kommunikationsplattform im Internet. http://www.gmx.net -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED] -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

Re: Servlet directory
The way you are trying to access this servlet implies a couple of assumptions: 1. Your servlet is in the default package. That is to say that it exist in WEB-INF/classes and not some directory deeper inside of that. 2. Your class is all lower case myservlet since that is how it is written on the URL your provided below. I think it is probably likely that #1 is true. However, I'm guessing that #2 is not. The general practice for naming classes is to use Capital letters for each distinct part of the class name. For instance, you probably named your class MyServlet, not myservlet. As such, the URL you provided won't work. It should be: http://localhost:8080/myapp/servlet/MyServlet Note that servlet and servlet-mapping entries in your own web.xml have nothing in particular to do with accessing your class through Tomcat's default servlet invoker which is mapped to /[your context]/servlet/*. The other thing you should look at is that the directory that your app is running out of exists in: $TOMCAT_HOME/webapps/myapp make sure that myapp is in all lower case. Oh, and make sure that there are no spaces in $TOMCAT_HOME. If you have it installed in a directory like Program Files, you can do the following (on Windows). I'll use my setup as an example. $CATALINA_HOME=C:\Progra~1\Apache~1\Jakarta\tomcat-4.1.8 The original path is: C:\Program Files\Apache Group\Jakarta\tomcat-4.1.8 Just use the tilde's to fix directory names which have spaces. The names with tilde's can be no more than 8 chars long. Restart Tomcat after using the hints above and things should work just fine.

newbie trying to run tomcat 4
Hi there, I've downloaded Tomcat 4 for the first time and have been pouring over these documents at the jakarta site trying to make sense of it all. I was able to set a context for a new webapp in server.xml and I'm able to navigate with Netscape to the web app with http://localhost:8080/mytest/index.html That part works just fine. I have a simple servlet sitting in my WEB-INF directory and my index.html file has a link in it that is supposed to launch the servlet: http://localhost:8080/mytest/servlet/sqlnames However, every time I try to click on the link, Netscape opens its SaveAs dialog box. For some stupid reason it seems to think I'm trying to save a file. Has anyone had that happen before? How do I make Netscape understand that I'm not trying to save a file. I just want to launch the servlet! What am I doing wrong? Alan -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
Tomcat4 and encodeURL
Hi ! I'm new to J2EE, and therefore I am trying each and every example of the programming book I've bought. Now I am learning session handling w/ the servlet API, and would like to use the URL-encoding style for keeping sessions, when the browser's configuration does not allow to use cookies. My (simple) example servlet is using the following instruction: String lifeCycleURL = response.encodeURL(/jtests/servlet/lifeCycle); out.println(A href=\ + lifeCycleURL + ?action=newSession\); This should modify my URL, adding ;jsessionid=xxx where xxx is the session ID. I can not get this to work, Tomcat will only handle sessions using cookies... Maybe I'm missing something?

Tomcat (or any other servlet container) will actually modify the URL only under the following circumstances: * There is actually a session in existence * The URL you are encoding points back into the same webapp * The container knows that cookies are not in use (because this is not the first request for the session, and we got the session id from the URL previously. In your particular example, encoding would only take place if the context path of your application is jtests. In addition, you must have called request.getSession() to create the session *before* executing the encodeURL call.

Re: newbie trying to run tomcat 4
Hi Markus, Does a servlet name always have to start with an uppercase letter? The reason I wrote the URL like this: http://localhost:8080/mytest/servlet/sqlnames is only because of how I wrote the web.xml file which looks like this: ?xml version=1.0 encoding=ISO-8859-1? !DOCTYPE web-app PUBLIC -//Sun Microsystems, Inc.//DTD Web Application 2.2//EN http://java.sun.com/j2ee/dtds/web-app_2_2.dtd; web-app servlet servlet-name sqlnames /servlet-name servlet-class MySQLNamesTest /servlet-class /servlet /web-app Maybe I need to change this somehow?

Application malfunctioning on TC4.1.7b
I have been working on my current project for past four month on TC4.0. Due to JSTL performance issue and the fmt message tag memory usage issue, I would like to try the 4.1 version. The application is runing fine on TC4.0. After I put the application on TC4.1.7b, I encounter the following two problems so far and can't use the application. 1. No resource files is loaded. I employ the i18n tags in the application. On the only page I can bring up, all text is the question mark. Do I need to configure the 4.1 version in order to load resource files? 2. I get the follow exception from the log in page: javax.servlet.jsp.JspException: class com.vernonwu.mm.accountinfo.model.AccountInfo : java.lang.InstantiationException: com.vernonwu.mm.accountinfo.model.AccountInfo The AccountInfo instance is not used in the page at all, but the next page after a user log in. I don't understand where this error comes from. Thanks for your helps. Vernon -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
