But today is one of those days that it just bites you in the ass. Tell me, does this make sense to you? Last night, when I was first trying to deploy the new version of my servlet, I used the Tomcat Project/Export to War file option in Eclipse to refresh my War file before attempting to install it on the Linux server. When things started misbehaving, I had a look at the War file and noticed that it was putting the beta 1.0 version of commons-fileupload in the jar. I thought that was messing me up so I searched both Eclipse and my hard drive and renamed or deleted every copy of the beta jar, every single one. When I renamed the jar, I added a .old to the end of the name, thus "breaking" the file association. I thought that would surely keep any program from mistaking it for a real jar file. Yet despite that, each time I did an export to my War file, I kept getting the beta version of the file upload in the War file despite the fact that no file named commons-fileupload-beta-1.0.jar was anywhere on my computer. I was baffled about how Sysdeo conjured up a file that didn't exist and put it in my War file. Does that many any sense to you? I just noticed that I still have one of the renamed files in my /server/lib directory on the Windows box; it is called commons-fileupload-1.0-beta1.jar.old: is it possible that Sysdeo was somehow grabbing that file and ignoring the ".old" suffix in order to put it in my War file? I wouldn't have thought that would be possible but I'm at a loss to think of any other explanation. I don't really want to keep flogging this dying horse but understanding this issue might give me some useful insights in understanding Tomcat in general, which could be handy in further problem solving Rhino - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I've deleted the beta jar from /common/lib and everything still works fine there. I don't have another copy of either the beta or the 1.0 jar anywhere else in that copy of Tomcat. Shouldn't Tomcat on the Windows box be failing the same way? Mind you, I don't import WAR files on the Window box; Eclipse and Sysdeo take care of everything for me. I'm pretty confident now that everything will work again as soon as I put the beta jar back in the /common/lib and put the current jar in the /shared/lib. (I'll be doing that on both the Windows and the Linux boxes, just to be safe, as soon as I find the binary of the beta jar.) Even though things aren't actually working again yet, I really appreciate all the help that you, John, and Andrew have rendered. It's much appreciated guys!

RE: Weird Problems installing servlets in Tomcat
Tomcat 4.1.24 comes with commons-fileupload-1.0-beta-1.jar bundled in the $CATALINA_HOME/server/lib directory. Tomcat needs this file to work, and also this version because the interface changed between this beta and the 1.0 final release. Tomcat is relying on the interface from the beta version (this may explain the NoSuchMethodError), so this file should be left where it is. If you wish your webapp to use the 1.0 release version of commons-fileupload, you can put in the WEB-INF/lib directory inside the .war file, or if you wish to share between several webapps, you can place the file in $CATALINA_HOME/shared/lib So, you may actually need 2 copies of commons-fileupload to get your application working: $CATALINA_HOME/server/lib/commons-fileupload-1.0-beta-1.jar $CATALINA_HOME/shared/lib/commons-fileupload-1.0.jar -Original Message- From: Rhino [mailto:[EMAIL PROTECTED] Sent: 22 July 2003 17:59 To: Tomcat Users List Subject: Re: Weird Problems installing servlets in Tomcat - Original Message - From: "John Turner" <[EMAIL PROTECTED]> To: "Tomcat Users List" <[EMAIL PROTECTED]> Sent: Tuesday, July 22, 2003 10:22 AM Subject: Re: Weird Problems installing servlets in Tomcat > Rhino wrote: > > > > > I'm still relatively new to Tomcat and Linux so I may be asking stupid > > questions; if so, I don't mean to be.

Re: Weird Problems installing servlets in Tomcat
That's probably the worst place to put it, according to the ClassLoader HOWTO: http://jakarta.apache.org/tomcat/tomcat-4.1-doc/class-loader-howto.html I would try $CATALINA_HOME/common/lib or better yet $CATALINA_HOME/lib. The former if ALL web applications PLUS Tomcat internals need access, the latter if just web applications need access. John Rhino wrote: commons-fileupload-1.0.jar is in /var/tomcat4/server/lib.

Is it in the correct location for the ClassLoader to find it? John Rhino wrote: Tomcat has suddenly started behaving rather strangely on our Linux server. I was hoping someone here could give me some insight into the reasons and some suggestions for resolving the problem. We are running Tomcat 4.1.24 on a Linux Mandrake 9.1 box. I wrote a servlet on the weekend which worked on my Windows XP machine but misbehaved slightly on the Linux server when installed there. Yesterday, I figured out what the problem was and revised the servlet. The revised version worked in Windows so I tried to install it in Linux. That's when the weirdness started: I can't install the WAR file in Tomcat. It always fails on the same error: java.lang.NoSuchMethodError: org.apache.commons.fileupload.FileUpload.setSizeMax(I)V I checked the Javadocs and found that the setSizeMax() method is part of the class FileUploadBase, not FileUpload, so I immediately suspected that the Linux box had an older version of the commons fileupload jar, which only went to version 1.0 at the end of June. I searched the Linux box and found commons-fileupload.jar, which is NOT the current version, and also found commons-fileupload-1.0.jar which IS the current version. I deleted the old one and now the only version of the jar on the server is commons-fileupload-1.0.jar. I tried installing the WAR file again but get the same error. I even tried installing a newer version of a different WAR file that doesn't do file uploads and IT failed on the same error. What is going on here?

Umm, no. From the classloader how-to, regarding the server/lib and server/classes: "These classes and resources are TOTALLY invisible to web applications" Move it to common/lib or keep a copy in server/lib and another in the WEB-INF/lib directory of your webapp. Yoav Shapira This e-mail, including any attachments, is a confidential business communication, and may contain information that is confidential, proprietary and/or privileged.

Re: Weird Problems installing servlets in Tomcat
commons-fileupload-1.0.jar is in /var/tomcat4/server/lib. I'm not sure if that's the *best* place for it but I thought that was one of the two places where you can put jars and have them visible to all the servlets that might need them.

Yeah. Compile with the components on your deployment classpath in the compile classpath. That's a standard practice to ensure consistency and avoid the errors you're seeing. FileUploaded went through a couple of 1.0 RCs before the final 1.0 release that did not work with tomcat. If you're really interested in the details, search the commons-dev list archive. Tomcat 4.1.26, which is looking like the next stable release at the moment, have the fileupload 1.0 final. Feel free to download and use it.

Re: Weird Problems installing servlets in Tomcat
Where is commons-fileupload-1.0.jar located? Is it in the correct location for the ClassLoader to find it? John Rhino wrote: Tomcat has suddenly started behaving rather strangely on our Linux server. I was hoping someone here could give me some insight into the reasons and some suggestions for resolving the problem. We are running Tomcat 4.1.24 on a Linux Mandrake 9.1 box. I wrote a servlet on the weekend which worked on my Windows XP machine but misbehaved slightly on the Linux server when installed there. Yesterday, I figured out what the problem was and revised the servlet. The revised version worked in Windows so I tried to install it in Linux. That's when the weirdness started: I can't install the WAR file in Tomcat. It always fails on the same error: java.lang.NoSuchMethodError: org.apache.commons.fileupload.FileUpload.setSizeMax(I)V I checked the Javadocs and found that the setSizeMax() method is part of the class FileUploadBase, not FileUpload, so I immediately suspected that the Linux box had an older version of the commons fileupload jar, which only went to version 1.0 at the end of June. I searched the Linux box and found commons-fileupload.jar, which is NOT the current version, and also found commons-fileupload-1.0.jar which IS the current version. I deleted the old one and now the only version of the jar on the server is commons-fileupload-1.0.jar. I tried installing the WAR file again but get the same error.
