[Bug 59604] New: Invalid url-pattern in servlet mapping
https://bz.apache.org/bugzilla/show_bug.cgi?id=59604
Bug ID: 59604
Summary: Invalid url-pattern in servlet mapping
Product: Tomcat 8
Version: 8.0.33
Hardware: Other
OS: other
Status: NEW
Severity: major
Priority: P2
Component: Catalina
Assignee: dev@tomcat.apache.org
Reporter: davec@aesclever.com
Created attachment 33854
--> https://bz.apache.org/bugzilla/attachment.cgi?id=33854&action=edit
log file
Tomcat 8.0.33 was deployed as-is on USS (Unix Systems Service)under z/OS V2R2.
Default apps failed to start due to "Invalid <url-pattern>" errors.
Somehow it thinks there are invalid characters in web.xml even though nothing
was modified.

That looks like some form of encoding problem. Tomcat 7.0.x uses ISO-8859-1 for
web.xml whereas Tomcat 8.0.x uses UTF-8.
Given that the contents of the files are correct for the given encoding this
looks like a JVM issue on your OS.
As far as I am aware, none of the Tomcat committers have access to a z/OS
system for testing. You are going to have to debug this one on your own unless
you can provide one of us with access to a test system.
Interesting... conf/web.xml is still using ISO-8859-1. That should be UTF-8.
Although I don't think it will help in your case it is worth changing to see if
it does.

... continue with my last comment:
I removed all the apps except ROOT and modified its web.xml by stripping off
the comments and the following:
<display-name>Welcome to Tomcat</display-name>
<description>
Welcome to Tomcat
</description>
I'm still getting the same parsing error even though there are no servlet
mappings in this bare minimum web.xml. It looks like an encoding issue, but I
guess the problem is not with the file contents but how it's being read.

You need to do the same to the global web.xml in conf/web.xml

Comment on attachment 33897

log file with bare bones conf/web.xml
Interesting. The exception is happening in the WebSocket
ServletContainerInitializer. It looks to be complaining that the URL pattern is
an empty string. However, the URL pattern is hard-coded to "/*".
There is no more debugging logging we can enable that will shed any light on
this. Some custom patches to add additional logging are going to be required.
While I can provide suitable patches, shell access to a test environment would
enable this to be investigated much faster.

Can you perform an MD5 signature of the conf/web.xml file so we can be sure
it's identical to the stock web.xml? Is it possible to get a byte-for-byte copy
of the file off that system somewhere we can see it?
Do you have any other XML-related utilities on that system that can be run
against the file to check for formatting, content, etc.? I'm thinking something
like 'xmllint' which is popular on *NIX systems (I recognize that z/OS is
different).
Maybe even an "od"-style byte dump copy-pasted into the comments, here?
(Actually, a better place for this thread would be the users mailing list since
it's not entirely clear that there is a bug here, yet.)

Anything that narrows down what is going on is useful.
My sugegstion is to try the following but keep in mind that you may have to
modify this as you go as you find out more information.
Strip Tomcat down to a single webapp that exhibits the problem (e.g ROOT).
Try different charsets in the XML prolog for conf/web.xml. UTF-8 and ISO-8859-1
as a minimum.
Remove content from conf/web.xml until you have the smallest possible file that
triggers the error.
Try writing a simple Java program to parse that file. Does that work?

Thanks for the shell access. It really speed up debugging this.
The bug has been fixed in:
- trunk for 9.0.0.M7 onwards
- 8.5.x for 8.5.3 onwards
- 8.0.x for 8.0.36 onwards
7.0.x and earlier were not affected.

--- Comment #3 from Konstantin Kolinko <kn...@gmail.com> ---
Note that it succeeded in parsing XML markup (the tag of '<url-pattern>'), but
contents of the tag is parsed as garbage. This is rather odd. Those patterns
are English as well.
Maybe those web.xml files were processed, overwrittem, broken by some tool?
Note that server.xml was processed correctly, otherwise the server wouldn't
start. Though a difference is that server.xml uses attributes to configure
values, while web.xml uses plain text content wrapped by elements.
Maybe try a different XML parser implementation. E.g. place a recent copy of
Apache Xerces-J into "endorsed" directory. From your logs its location is:
-Djava.endorsed.dirs=/u/aes/apache-tomcat-8.0.33/endorsed
Some (unrelated) oddity in the logs:
VersionLoggerListener.log Command line argument: -Djava.class.path=.
VersionLoggerListener.log Command line argument:
-Djava.class.path=/u/aes/apache-tomcat-8.0.33/bin/bootstrap.jar:/u/aes/apache-tomcat-8.0.33/bin/tomcat-juli.jar
Where the first incorrect value of "-Djava.class.path" argument comes from?
Note that such questions are normally asked on the users mailing list. You need
help from fellow users to help find the root cause here.

The problem still exists after each step:
1. as each app is removed
2. with only ROOT app
3. after removing ROOT/WEB-INF/web.xml
4. with a minimum conf/web.xml
I will upload the minimum conf/web.xml and catalina.out

Please try the following:
Clean Tomcat install.
Confirm problem exists.
Remove apps one by one until only ROOT is left.
Confirm problem still exists as each app is removed.
Remove ROOT/WEB-INF/web.xml
Confirm problem still exists.
Remove content from conf/web.xml until you have the minimal conf/web.xml that
triggers the problem.
I'm expecting a minimal conf/web.xml with a single Servlet definition and
associated Servlet mapping to trigger this issue.
Experiment with different encodings for the XML prolog for conf/web.xml. Test
UTF-8 and ISO-8859-1 as a minimum.
Report your findings.

Both versions (8.0.33 and 7.0.67) were deployed as-is without any changes,
using the same JAVA_HOME. 7.0.67 runs OK without any problem.
Note:
z/OS shell is EBCDIC-based but it can support ASCII shell scripts (e.g.,
Tomcat's startup.sh, etc.). Below is my "init" script to set up the automatic
conversion.
#!/bin/sh
