TitleAccented Characters Converted Badly

Non latin or non-ASCII7bits characters in certain links are incorrectly escaped by the latest 2.4 engine.

For example, my user page JérômeDuprez is unreachable through a link:

  • the link points to JÃRÃ Me Duprez, converted as, which does not exist
  • whereas it is OK if I write it down in the URLérômeDuprez, which gets rewritten as

I spotted the problem with the accented characters in my name, but it also surfaces with asian characters, and presumably lots of non-7bits-ASCII characters. That's why I dare to increase the severity.

Works perfectly on Tomcat 5.5.16 on OSX... It's probably a configuration, not an engine issue...

Yup. Tomcat 5.5. requires URIEncoding="UTF-8" in the proper Connector block of the server.xml file. For example, for the AJP 1.3 connector with Apache, it might say:

    <!-- Define an AJP 1.3 Connector on port 8009 -->
    <Connector port="8009" className="org.apache.coyote.tomcat4.CoyoteConnector"
               enableLookups="false" redirectPort="8443" protocol="AJP/1.3"
               connectionTimeOut="120000" acceptCount="200" maxThreads="250"
               minSpareThreads="25" maxSpareThreads="75" URIEncoding="UTF-8">
         <Logger className="org.apache.catalina.logger.FileLogger"
              prefix="apache_log." suffix=".txt"

Should be working now. -- JanneJalkanen

-- JDuprez right, I configured this for my HTTP connector on 8080, and it worked. Thanks for the support.

Even if it turns out not to be a JSPWiki bug, it deserves some mention in the install documentation (I installed Tomcat out of the box on WinXP, default configuration really). OK I know your answer: feel free to edit the install page :o) Fine, I'll do that.

Update: I reopen this bug based on new info below. I lower severity though, as there truly is a workaround.

Functionally it appears as a regression between 2.2.33 and 2.4.0 : until I upgraded my Wiki engine to 2.4.0 it did not exhibit this problem regardless of the URIEncoding setting.

  • To make sure, I have:
    • removed the URIEncoding field from server.xml
    • run two Wiki web apps (one jspWiki 2.2.33 and another jspWiki 2.4.0) in the same Tomcat instance
  • they demonstrate different behavior:
    • 2.4.0 exhibits the problem
    • whereas 2.2.33 works fine
  • when I specify URIEncoding="UTF-8", both versions work fine.
If you have time to investigate this issue, it sure helps deployment that JSPWiki works without having to touch the JSP container settings - ease of installation and configuration is indeed one of the strong points of JSPWiki.

The reason why they are different is probably because you have enabled ShortViewURLConstructor on 2.4.0. Tomcat decodes paths using different rules than parameters...

-- JanneJalkanen

--JDuprez Fair enough, sounds logical. Note however, that I didn't explicitly specify this URL setting; here is the extract of my, related to URLConstructor. notice that everything is comented out (default setting):

#jspwiki.urlConstructor = DefaultURLConstructor
#jspwiki.urlConstructor = ShortViewURLConstructor
#jspwiki.shortURLConstructor.prefix = /wiki
Is ShortViewURLConstructor the default?

Apologies for insistively following up. Strictly speaking, if you're right, this is not a bug report but a support request. Please let's keep the bug open until the reason is sorted out though...

No, the DefaultURLConstructor is the default. What kind of URLs are you getting?

-- JanneJalkanen

-- JDuprez Well, the same as witnessed on this site when I reported this bug: [JérômeDuprez] generates a link http://localhost:8080/MyWiki/Edit.jsp?page=J%C3%A9r%C3%B4meDuprez, to a page named JÃRÃMeDuprez.

To be honest I'm less concerned by this issue now that I've configured the URIEncoding flag on the couple of Tomcat instances I routinely use. I'll redo the test next time I upgrade the wikis engine version.
