Getting Tomcat Apache To Run On Microsoft Windows 7

Posted by Jithen (J) Singh in Development on Monday, May 4, 2009 | 48 comments

So the last few days I have been updating my work laptop to Microsoft Windows 7 Release Candidate. I have now successfully reinstalled most of my existing software. This also includes a new installation of ArcGIS 9.3.1. I am very impressed with Windows 7 Release Candidate, Microsoft has done a great job with this release. A few new features but also tons of bug fixes.

One of the last pieces of software I needed to reinstall was Tomcat Apache. I use Tomcat Apache for a few web applications and thus the need to install this. I downloaded the latest version. Tomcat Apache 6.0.18. Installation is as per normal. Attempting to start the Tomcat Apache process you get the following:

1

2

Tomcat Apache fails to start with the above error. The error isn’t very informative so digging further by looking at the Apache Tomcat logs you get the following:

3  

Having a look at the logs we can see that the JRE is reporting a missing module which cannot be found. The file that is missing is named: msvcr71.dll. While this file should exist in your JRE folder, Tomcat Apache cannot access it.

The simple fix for this problem is to copy the msvcr71.dll from your JRE folder to the Apache Tomcat /bin folder as per screenshot below.

4

Attempting to start the Tomcat Apache service again will work fine.

5

While the fix is really simple, it too me a while to figure this one out and research it. I am not sure whether this applies to x86 or x64 versions or both but I am running Windows 7 x64. There are a few issues I have found with ArcGIS 9.3.1 and ArcGIS Server 9.3.1 on Windows 7 so I’ll blog about them as soon as I can.

    I’ve successfully started tomcat on windows 7 RC 7127.

    I’ve changed tomcat folder permission by adding write privilege to tomcat folder.

    Great! It worked like a charm! Didn’t notice any other compatibility issues regarding Windows 7. I think Microsoft finally did some really good work with this OS.

    Hi, this tutorial seems very usefulll… but it doesn’t work for me..

    I have a Windows 7 Professional on a Dell XPS16, i tried to installa Apache Tomcat 6.0 and i had the problem you fix… unfortunately i haven’t solve it. In my Java installation folder i haven’t the file <msvcr71.dll> so i downloaded it but it still doesn’t work… I reboot several times. I have java 1.6 installed, could it be that the problem??

    This really seemed to help quite a few people. It didn’t do anything for me. Does anyone else have any ideas? Using 64 bit, redownload and installed tomcat and JDK etc., etc.

    Any help would be appreciated.

    what makes it work?

    I installed 32 bit JVM, then downloaded apache-tomcat-6.0.26-windows-x86.zip(not the windows installable). Extracted it into c:\apache\ and tried registering the Tomcat as a service by clicking on $CATALINA_HOME\bin\service.bat. It failed with a message stating that registration failed. But it is now working with this msvcr71.dll inside $CATALINA_HOME\bin\.

    Please let me know about what was earlier missing or what have made it to work now??

    Had the same problem, solution suggested here didn’t help (got a different error in the log, something like ‘cant start service’).

    Discovered that I had installed the wrong Java version (32x, not 64x as my system was).

    So check your system properties (open a Windows Explorer, right click on ‘Computer’, select properties). On the properties page, check the ‘System type’.

    Mine was ’64-bit Operating System’. So I installed a new Java version. Then everything worked fine, with no copying of any files.
