The main resource set specified is not valid
Hello - I am encountering a problem, on OpenSuSE15.0 and on
OpenSuSE15.2, which suddenly appeared, possibly via an update or
possibly from me working on Tomcat and doing something that I can't find
a way to resolve. I am now getting a rather obtuse set of error messages
for all my webapps, which is coming from a series of stack walk-back
traces (shown without the actual program trace messages) from the
Tomcat/Catalina logfile -
9-Dec-2020 13:47:22.732 SEVERE [main]
org.apache.catalina.startup.HostConfig.beforeStart Unable to create
directory for deployment: [/usr/share/tomcat/webapps]
19-Dec-2020 13:47:22.734 SEVERE [main]
org.apache.catalina.core.ContainerBase.startInternal A child container
failed during start
java.util.concurrent.ExecutionException:
org.apache.catalina.LifecycleException: Failed to start component

Caused by: org.apache.catalina.LifecycleException: Failed to
start component [org.apache.catalina.webresources.StandardRoot@704921a5]
Caused by: java.lang.IllegalArgumentException: The main resource
set specified [/usr/share/tomcat/webapps] is not valid
The last error message - java.lang.IllegalArgumentException seems to the
the pertinent one telling me the path /usr/share/tomcat/webapps is not
valid. Doesn't tell me why it is invalid, sigh, when will programmers
write decent user friendly error messages which can actually help?
Anywise, on my system I am guessing that the problem is that this app
path is actually a double soft link i.e.
quasar:/usr/share/tomcat # ll -d /usr/share/tomcat/webapps
lrwxrwxrwx 1 root tomcat 19 Jul 12 2019 /usr/share/tomcat/webapps ->
/srv/tomcat/webapps
quasar:/usr/share/tomcat # ll -d /srv/tomcat/webapps
lrwxrwxrwx 1 root tomcat 38 Nov 23 14:58 /srv/tomcat/webapps ->
/websites/home/marc/domain.com
quasar:/usr/share/tomcat # ll -d /websites/home/marc/domain.com/
drwxrwxr-x 39 marc users 4096 Aug 13 23:52 /websites/home/marc/domain.com/
I did try shortening this to a single soft link but that didn't change
anything. The only other possibility I can think of is that Tomcat may
have troubles reaching a file system on a different mount point???
/webapps/... is on a different disk drive and is a mount point.
These two environment variables are defined in tomcat.conf -
CATALINA_HOME="/usr/share/tomcat"
CATALINA_BASE="/usr/share/tomcat"
The host declaration for this application, in server.xml, is -
The context.xml file is -
WEB-INF/web.xml
WEB-INF/tomcat-web.xml
${catalina.base}/conf/web.xml
Sure would appreciate any help offered and thanks in advance. I been
spending lots of hours trying to noodle this problem out and just not
getting anywhere! A puzzler is that I had Tomcat working on OpenSuSE
15.0 at one time and this error message surfaced when I was trying to
port Tomcat to OpenSuSE 15.2. I may have done something bad that broke
Tomcat on OpenSuSE 15.0 but can't remember what I might had done that
might have broken Tomcat. A couple other tidbits of information that
might prove helpful -

So for example, if I use the alias in the URL - http://www.mydomain.com/jsp-examples that I send to the Apache server, and it in turn forwards that request to Tomcat as http://www.mydomain.com/examples/jsp, I would prefer that the response, sent back to the user, contains the original, aliased or unaliased, version of the URL that he/she typed, and not just the resolved version.

Thanks again in advance for any and all offers of help, thoughts, and replies... Your best bet is to name the context in Tomcat to be whatever you really want the URL path to be. This will remove all kinds of problems you are likely to see in the future because of your decision to try to rewrite URLs. I never understand why people would rather spend a great deal of time configuring around the fact that this simple command will get everything working without any other issues: $ mv webapps/name-you-have webapps/name-you-want +10 Because once you start playing with Aliases and RewriteRules, you are setting yourself up for a lot of future additional complications in terms of Redirects, Authentication, etc.. most of which you cannot even imagine right now. Thanks Christopher, Andre for your comments and I will certainly take them under consideration. If I were working in a simple environment where all I had to do was to focus on Tomcat and Apache I would certainly agree with you. Your simplistic solution of renaming directories would indeed be the correct choice. The problem is, is that the real world is not quite so accommodating. I am trying to support a team of users who are using other third party applications and also using cross-sectional tools that require multiple resources/directories in the Tomcat/Apache web directories, that all need to be coordinated. Some of this can be solved with directory renaming or links, but in some cases it becomes a question of whether the dog is wagging the tail or the tail is wagging the dog in terms of the amount of work involved to solve a problem; such as a simple Tomcat/Apache alone related answer (directory renaming) implies. So I am exploring the choices I have within the Tomcat/Apache tool space in order to determine what choice is best. If indeed the tools available within Tomcat and Apache are so odious to use, then yes I will also have to explore the option of changing other tools, software, and configurations in order to accommodate Tomcat and Apache. My understanding of Tomcat and Apache is that they are supposedly robust enterprise grade tools, designed to work in complex environments. So my hope is that issues like this have been already addressed with elegant solutions. ;-) FYI I am using the jsp and servlet examples here as just a simple model of what I want to accomplish. I could really care less about those particular web applications. Marc

Apache mod_jk connector question about alias
Hello - My apologies if this has already been asked or the wrong mail list, but Google is not coming up with an answer for me, so here goes... I am trying to set up the mod_jk connector between an Apache HTTPD server and Tomcat with the intent of supporting virtual hosts, and serving static content from the Apache server and forwarding jsp and servlet requests to Tomcat. Typical scenario I know... Most of this I have working but the trouble I am having is with the use an Alias directive for the Apache server. Following instructions for the JSP examples that came with my distribution for Tomcat 8, I created a configuration for # The following line makes apache aware of the location of # the /jsp-examples context Alias /jsp-examples "/srv/tomcat/webapps/examples/jsp" Options Indexes FollowSymLinks AllowOverride None # Controls who can get stuff from this server.

Using the JK debug level and monitoring the mod_jk.log file I can see what is going wrong, I just don't know how to rectify it - [Mon Oct 17 09:28:01.145 2016] [30237:139868423546816] [debug] ajp_connection_tcp_send_message::jk_ajp_common.c (1208): sending to ajp13 pos=4 len=469 max=8192 [Mon Oct 17 09:28:01.145 2016] [30237:139868423546816] [debug] ajp_connection_tcp_send_message::jk_ajp_common.c (1208): 12 34 01 D1 02 02 00 08 48 54 54 50 2F 31 2E 31 - .4..HTTP/1.1 [Mon Oct 17 09:28:01.145 2016] [30237:139868423546816] [debug] ajp_connection_tcp_send_message::jk_ajp_common.c (1208): 0010 00 00 0E 2F 6A 73 70 2D 65 78 61 6D 70 6C 65 73 - .../jsp-examples [Mon Oct 17 09:28:01.145 2016] [30237:139868423546816] [debug] ajp_connection_tcp_send_message::jk_ajp_common.c (1208): 0020 2F 00 00 0D 31 39 32 2E 31 36 38 2E 31 30 2E 31 - /...192.168.10.1 This excerpt shows that the Apache server is sending a message to the Tomcat worker telling it to find a resource "/jsp-examples" which of course doesn't really exist and so Tomcat reports a "Not Found" failure. What I want is for the Apache server to send the actual location that this alias is mapped to i.e. "/examples/jsp", which is what actually exists in the Tomcat context. I can fool Tomcat into handling this alias request by creating a link named jsp-examples -> examples/jsp within the Tomcat webapps directory but that seems like a hack and not something I want to have to do/maintain for all the other resources I will want to handle via alias commands. Is there a magic incantation that I am missing?

So, stick with the filter. OK, I kinda gathered that a filter is applied to everything served up by the server, before servlets are invoked... So it makes sense that a filter has to be used (if I am understanding this correctly) for JSP Servlets Technically speaking, the filter wraps the call to the actual servlet (or, even, other filters that get called before the servlet). They can act either before or after the servlet, or both. The SSI filter wraps the request handed-off to the filter chain (which ultimately ends by calling a servlet) and buffers the response. After the rest of the filter chain has run (and presumably produced output), the SSI filter completes its task by actually running that buffered-output through the SSI processor to actually *do* all of the SSI stuff. The result is then sent to the client. Honestly, I'm not sure why the SSI Servlet is even included: the DefaultServlet handles files on the disk, etc. quite nicely and the SSI Filter can be used to filter them, too. See my related post on the SSI Filter implementation if you're interested. Aww THANKS for the explanation Christopher! That helps a lot... And I think I follow you on the SSI Servlet, I was unsuccessful in getting SSI to work with it, and have not gone back and retried... The Filter approach seems more intuitive to me.. Note that you should be able to set up SSI in a single webapp instead of modifying the conf/web.xml file as described in the SSI documentation. I find this cleaner, as you will only end up making SSI available in a specific webapp instead of across all webapps deployed onto the server. Thefilter-mapping itself should definitely only be included in your webapp's META-INF/web.xml file. Not sure I fully understand you here, so please forgive my lack of understanding... I do want this SSI feature to be available across all the webapps deployed on our server. As I mentioned previously, we want to provide some services that users can access, by simply including a server side include statement that will effectively include these features on their web pages. Gotcha. Feel free to enable this site-wide, then (using conf/web.xml). Evidently, you'll also have to make all contexts that want to use SSI privileged. I'm not entirely sure that's true if you enable it at the top-level as you are doing. Please let us know. I changed to Context tag declaration in the Context.xml file to Context privileged=true and that enables SSI for all my webapps (so far as I have tested it) Again thanks for your time and help!

Question on SSI
Hello - I am running a Tomcat6.0 server both stand-alone and with Eclipse, and am in the process of developing a webapp that I will want to make available to all our users via a server side include statement. I have this working in a limited sense, in that I got it working using the filter version but was unsuccessful getting the servlet version working, which is acceptable. (I am not clear on what the real difference between the two approaches is, documentation is non-existent as far as I could find). Anywise, what I have working, works so long as the !--#include virtual=somefile.html -- is in a .shtml file, but this will be unacceptable. I need this feature to also work from inside normal .html and .htm as well as .jsp files as that is what our users will expect. I have fooled around with the filter-mapping segment in the server's web.xml file but so far no joy in finding a solution. Searches (lots of em!) on the internet have not provided me with an answer, though I have gotten hints that it is doable. Could some kind guru help me grok this and guide me to the light?

If I'm right it will work but shtml won't. Really need a regularexpression writer. Thanks Wesley!!! That did the trick, and yes, shtml does not work... But this should be ok for our needs, our users don't create .shtml files, and this also worked for .jsp and .htm files as well as .html...

When crafting your own pattern, don't forget that a mime content type may be followed by an optional character set in the form mime/type; charset=set that you must take into account. Default is text/x-server-parsed-html(;.*)?. Green emphisis assuming the mailing list allows html mail is mine. Perhaps this does say it, Wesley, but I am going to argue that, like a lot of documentation, too much is assumed about the readers level of background understanding. In this instance, as an outsider, I do not understand the model inside the Tomcat server about just how the contentType parameter is going to be used, or what text/x-server-parsed-html(;.*)? is, does, or will do. Internet searches resulted in nothing informative, so to me this is a black box using a magic incantation and I do not have a way to grok how to manipulate it. Same applies to your answer of using text/html(;.*)? for the content type. This is perhaps a very unusual form of a reg expression, if I were to interpret it, I would guess it is trying to match a string text/html; followed by an arbitrary set of characters, but I cannot be certain, and perhaps the semi-colon is being used in a way that I am unfamiliar with... And if I am correct, I still do not understand what string is being matched against, though I might take a wild guess and guess that it is matching the content declaration in the meta tag of an html document... but then I got no clue what test/x-server-parsed-html(;.*)? is going to match against, and I cannot find any information about such a document type, so I remain lost... Some mime types are more intuitive than others, but not entirely. While I can understand the need to associate simpler concepts, like a jpeg image with something to handle .jpeg files, I really cannot say I understand the mapping fully to understand just how that mapping is done. Many sites are willing to list these mime types and repeat the same sort of list that is found in the web.xml file, but they do not reveal just what is going to happen or how the mapping gets modeled/translated into an action. So, IMHO what is needed is some additional links in the documentation, to places where concepts such as these are better defined... Also as a side note you can have multiple mappings for one filter.So in production based on your requirements I'd do the following filter-mapping filter-namessi/filter-name url-pattern*.html/url- pattern /filter-mapping filter-mapping filter-namessi/filter-name url-pattern*.htm/url- pattern /filter-mapping filter-mapping filter-namessi/filter-name url-pattern*.jsp/url- pattern /filter-mapping That should fix it. In case your wondering what mime types that are used in tomcat they are all listed in the web.xml in the conf subfolder of tomcat. Again thanks for your taking the time to help me, and I know I got a lot of learning to do yet... I will add your additional filter-mappings to my web.xml file, as it seems to be more limiting/appropriate. As for the list of mime types, see my above comment, a simple list is not sufficient for me to understand how and why a particular mime type item should be used... An reading the official documents on mime types is pretty intimidating/overwhelming... What is needed is a link to a simple boiled down description that allows the user to quickly grasp and understand these concepts.. Marc...
