(yes i could put hte Dtd in the demo.war ... but...i does not explain the strange behavior... ) Thanks Maxime The important issues for resolving correctly are: - You must use the correct public identifier in your config files. That is what the XML parser uses to match things up. - You must include struts.jar inside WEB-INF/lib of your web app. - You must ***not*** have struts.jar on your classpath. Craig McClanahan
Re: More on running Tomcat+Struts w/o internet connection
Hello,
I'm also interested in a solution of that problem. Admittedly the
subject-matter is not the struts-config.dtd but rather any dtd of any
(custom) xml-document struts works with.
TIA

My coworker posted the original question in the Running Tomcat+Struts w/o
internet connection thread, but since I'm the one trying to overcome this
particular problem, I thought I'd add some more detail. First off, we're
using Tomcat 3.2.1 or 3.2.2 (not sure) and Struts 1.0.
The DOCTYPE line of the struts-config.xml by default looks like:
!DOCTYPE struts-config PUBLIC -//Apache Software Foundation//DTD Struts
Configuration 1.0//EN
http://jakarta.apache.org/struts/dtds/struts-config_1_0.dtd;
If I run tomcat disconnected from the network I get the following:
resolveEntity('-//Apache Software Foundation//DTD Struts Configuration
1.0//EN', 'http://jakarta.apache.org/struts/dtds/struts-config_1_0.dtd')
Not registered, use system identifier
Parse Fatal Error at line 3 column -1: External entity not found:
http://jakarta.apache.org/struts/dtds/struts-config_1_0.dtd.
whereupon Tomcat barfs and stops loading. It was suggested to use a
'file://' style URL to fix this. That works fine, (i.e.
'file:///c:/foo/bar/struts-config_1_0.dtd') but it demands an absolute file
path. Any attempt to use a relative path (such as
'file://struts-config_1_0.dtd') has failed with the same 'external entity
not found' error as above. I've tried various permutations, but either it
doesn't work, or I can't figure out what the current working directory is
that the URL will base itself off of (tried tomcat/bin, webapps,
webapps/myapp, webapps/myapp/WEB-INF).
So, how about specifying the file directly, as in:
!DOCTYPE struts-config PUBLIC -//Apache Software Foundation//DTD Struts
Configuration 1.0//EN struts-config_1_0.dtd
Well, here's the resulting error:
Parse Fatal Error at line 3 column -1: Relative URI struts-config_1_0.dtd;
can not be resolved without a document URI.
Even though XML Spy thinks this is OK, obviously tomcat wants a little more
information. I poked around in the XML Bible, but couldn't find anything to
tip me off as to what to include in the XML that would make this error go
away.
All I want to do is have the struts DTD be a local file, referenced with
some sort of resolveable relative path. An absolute path just can't be
worked with, and we cannot guarantee a network connection. Any more ideas?
Thanks!

Running Tomcat+Struts w/o internet connection
We are trying to run Tomcat + Struts to run our web application without an external internet connection. We are running into a problem because our struts-config.xml has an external reference to the struts-config DTD. What is the proper way to modify struts-config.xml to reference a locally defined DTD and where would that file normally reside in a standard Tomcat installation? Thanks.
RE: Running Tomcat+Struts w/o internet connection
Open the struts-config.xml, change the head
!DOCTYPE struts-config PUBLIC
-//Apache Software Foundation//DTD Struts Configuration 1.0//EN
http://jakarta.apache.org/struts/dtds/struts-config_1_0.dtd;
To:
!DOCTYPE struts-config PUBLIC
-//Apache Software Foundation//DTD Struts Configuration 1.0//EN
file://c:/{where_your_DTD_is}/struts-config_1_0.dtd
I think that will work.

Of course you can use relative directory, and put the DTD file into your
war.

Hi,
I think that problem has been fixed since Struts 1.0, but I'm not sure.
Do you have a new release from Struts?
The solution with file://c:/... is IMHO a problem if you want to
deploy your Application (e.g. in a war-File).
Who guarantees you, Tomcat or JRun or ... will be installed on Drive C?
Currently I have a similar problem: I have a XML-File (retrieved by
SOAP) and do parse it with Digester.
That is no problem. If I want to validate that Document, I do it by
writing the DTD-Reference into the XML-File
( !DOCTYPE root SYSTEM xy.dtd ) and by calling
digester.validate(true).
The Drawback is, that I must put that DTD in the tomcat/bin Directory,
otherwise it would **not** be found.
Then I tried to use the digester.register method. But it seems, I does
not work, as I want.
What I want is: To put the DTD file in some custom directory and use it
to validate the XML-File (that I get wrapped in in a SOAP Document).
Who knows, how to do that?
Cheers
Hartmut

RE: Running Tomcat+Struts w/o internet connection
I was following this thread, and I tried to use a relative directory of the
type:
file://./struts-config_1_0.dtd
When I attempted to start tomcat I got the following message:
resolveEntity('-//Apache Software Foundation//DTD Struts Configuration
1.0//EN', 'file://.') Resolving to alternate DTD
'jar:file:/C:/dev/jbproject/TMate/tmate/WEB-INF/lib/struts.jar!/org/apache/s
truts/resources/struts-config_1_0.dtd'
and then my app worked correctly. Simarly, you could change the http path
to point to a null object. ex:
http://this.domain.does.not.exist.org/struts/dtds/struts-config_1_0.dtd;
It seems that if the file can't be found where specified, struts resorts to
a struts-config_1_0.dtd file embedded within struts jar. This may only work
in struts_1.0.

Re: Running Tomcat+Struts w/o internet connection
You shouldn't have to change the XML. There are local copies of the DTD in
struts.jar, and should be registered and loaded when you start Tomcat up.
Which build are you using (source vs binary, and release vs beta)? This
should be working just fine in the later builds.
