RE: Multipart/form-data

RE: Multipart/form-data
Thanks, this is exactly where the problem is. I just switched my application from ajp13 to ajp12, it works fine with uploading both binary and text files. I never thought it could be the connector problem on the tomcat side. Can somebody tell me where to find all the known problems of tomcat, please?

Re: Problem with Tomcat as NT service
I never tried to run tomcat as a service, but the same thing happened to me before. So I hope the following will help: I had a servlet class which also has a main() function for dos-console testing. I found that I have to use different jdbc driver to open the same Access datasource. The reason, as I later found out, you have to setup the classpath correctly in both cases so that tomcat can find the proper driver. I suspect this could be the reason of your problem. As I understand, the environment variables can be seen by a service can be different from those by a regular windows program. The reason behind that involves more of the Windows OS system knowledge. But I suggest you try to print out the necessary class path or other related environment variables in both cases. Hope it helps.

RE: file upload servlet
I am very surprised. I tried the same version.
Here is the code I am using. As you can see, (or somebody can see), this is from
upload.war (the sample came with the multirequest class) with some
modifications.
If everything works ok, I should be able to see all the parameters and files
listed. However, it only worked for text files. For binary files, results vary
from server error to exception in the MultiPartRequest constrcutor. The only
difference I could find between your code and mine is mine is in a servlet's
doPost() function?
Now I am really confused. Help!
Is it related to tomcat somehow. I am using tomcat 3.2.1 with apache 1.3.14 on
WinNT4.0.

Subject: RE: file upload servlet
Thank you, Tim.
I tried this one first before I posted the message. It worked only for text
files.
I tried two versions. The very first and the very last one.
Did you work with this library before? How did you upload binary files?

servlet mapping
Hi, I recently moved from tomcat 3.1 to tomcat 3.2.1. I found the speed of start-up/shutdown is improved dramatically, and I don't have to manually kill my apache and restart it anymore. However, with the upgrade, I found something else strange happened. I defined the following servlet so that whenever the user navigates to my web application, it will automatically invoke my servlet to generate a welcome page for him. For instance, http://myserver.com:8080/myapp will invoke the PWFrontPageServlet. It worked well with 3.1. However, it does not work in 3.2.1. I have to manually type in http://myserver.com:8080/myapp/index.html to invoke the servlet. I tried to set the welcome-file-list element in web.xml, it didn't work. Can somebody please help me out?

Re: Deny web-inf access (security problem)
I am surprised this could happen, you must use a customized configuration file. Usually, the default conf file generated by tomcat contains at least something like this for your web-inf folder. You may want to add this to your conf file or web configurations somewhere.

tomcat_apache.conf tomcat.conf
Hi, I started using tomcat with Apache recently. I am confused by tomcat.conf and tomcat_apache.conf. According to the User's Guide, tomcat_apache.conf is automatically generated by tomcat. So I will have to: 1) include tomcat_apache.conf at the end of Apache's httpd.conf. 2) start tomcat first, so that tomcat_apache.conf can be generated. However, on another section of the User's Guide named "Making Apache Serve your Context's Static Files", I'm instructed to add something to the tomcat.conf so that tomcat will leave static files for Apache to process. So my questions: How are tomcat.conf and tomcat_apache.conf used by tomcat? Especially, in what order does tomcat read these two files? Can somebody help me out, please? Ma, Yanbin
