  • 0

I deploy a war to my Tomcat 6.0.35 on Win7 64bit and when I use full-interface query page (I mean form.jsp) in Solr Admin to query 2 Chinese character (say it’s C1C2) , the debug info shows:

<lst name="debug">
  <str name="rawquerystring">æ°è</str>
  <str name="querystring">æ°è</str>
  <str name="parsedquery">NEWSID:æ°è</str>
  <str name="parsedquery_toString">NEWSID:æ°è</str>
...

You can see C1C2 becomes æ°è. I deploy same war file to Tomcat on Linux or on another Win7 64bit of my colleagues’ computer, the encoding acts well. Does anyone know why and how can I avoid this problem?

Thanks in advance!

    I solved the problem. The evil is Win7’s File Virtualization feature. By default, Win7 will enable this feature on several well-known folders, e.g. Windows, Program Files, ProgramData, etc. The effect is that under some conditions, a file will have dual contents and this just happen to occur on my server.xml.

    The workaround is clean things in ‘c:\Users\<user account>\AppData\local\VirtualStore‘. The long-time solution is “Don’t install Tomcat in these well-know folders. If you insist, be sure not to install-‘n-uninstall too many times.”

    ~~~ How I find this problem (you may not need to see this) ~~~

    Two words: “Pure luck”. When I use some xml editor to edit tomcat-users.xml and add a user ‘test’. I restart Tomcat but can’t login to use manager UI. I recheck tomcat-users.xml and see that user is indeed set. Even I uninstall-‘n-install different version of Tomcat, login still fails.

    Then I use notepad to edit tomcat-users.xml and I’m astonished to see it’s the original version Tomcat has installed. After editing it with notepad and restart Tomcat, I can login now.

    Very quickly, my thoughts flashes to server.xml and I use notepad to see it. Ah Ha! There’s no URIEncoding attrbutes in connector tag. After fixing it, The problem is solved.

    In my case, my xml editor and IE both show wrong version, but my other browers and notepad show correct version. I still don’t know what algorithm does Win7 uses on File Virtualization, so I think workaround will live for a while.
