Two JK2 Connector Questions
1. Are the JK2 connector releases decoupled from Tomcat? 2. When is connector release 2.0.4 expected to be released? I'm specifically interested in BUG # 13869. mod_jk2 becomes confused when client breaks the connection http://nagoya.apache.org/bugzilla/show_bug.cgi?id=13869 If this bug needs to be verified I can do that as we have a repeatable test case. thanks, __ Do you Yahoo!?

Re: JK2 and IIS 4.0 performance issue
I have been using Tomcat 4 with JK2 connecting to IIS on Win2K and have had little or no performance loss when compared to using iPlanet. There is a small hit when compared to accessing Tomcat directly. But that is a *small* hit. One developer I know has also been using XP to support this configuration and he has not mentioned any slowness relative to Win2K. I hope that this information helps guide you, e --- Thomas Nybro Bolding [EMAIL PROTECTED] wrote: Greetings list, I have just upgraded my Tomcat 4.1.27 using JK to Tomcat 5.0.16 using JK2. In both cases I connect to IIS 4.0 running on Win NT. Performance is now extremely poor when the JSP pages are being served through JK2 whereas everything works smoothly when requesting port 8080. I therefore assume it is the JK2/IIS connection which causes the penalty. My questions are thus: - is anybody connecting IIS 4.0 to Tomcat using JK2 with no or little perfomance penalty? And in that case which default parameters have been changed? - would upgrading to Windows 2000 and IIS 5.0 solve this ussue? - I have read the isapi_redirector2 is for IIS 5.0 on Windows 2000 whereas isapi_redirector2.02 is for IIS5.1 on Windows XP? Can this be confirmed? Which version is for IIS 4.0 then??? Any help will be highly appreciated!

Re: integrating tomcat 4.04 into iplanet 4.1 using nsapi_redirector on linux
Wow. that was long. Suggestions: 1. In workers.properties change localhost to the FQDN (Fully Qualified Domain Name). 2. Check to see if iPlanet is in fact forwarding the request to the redirector OR if it is serving the request itself. Frequently folks make the content under tomcat available to the iPlanet Web Server via a symlink and this obfuscates the matter. Though this technique is good for delivering static content and speeding up the overall process by reducing the burden on the redirector. To check if iPlanet is forwarding the request to the redirector, tail -f iPlanet log/access and nsapi.log. There should be a collection of activity on both sides for each request. If you have it on the iPlanet side but not the redirector side (of iPlanet) then you have a problem in obj.conf. My experience is that you have a problem in obj.conf, almost always. If you have doubts then attach obj.conf to your response. I'll take a look at it. emmett --- Jerry Birchler [EMAIL PROTECTED] wrote: Has anyone done this? If so, I would like some help. I have compiled the redirector and validated that it is getting invoked, my connector is up and listening, I validated that the class files used for ajp13 are getting invoked, I set up my obj.conf file, the server.xml file and my workers.properties file, but I only get this when I hit a JSP page: HTTP 500 - Internal server error Internet Explorer After playing around a bit more, I get a little better results() in that the browser returns html, but it is not running the JSP. Instead all code between % and % shows up when I view the page source, but is otherwise hidden. When I view a JSP in netscape's doc root, I see the entire text rendered and all code between % and % as if it were just text. So, the bottom line is that a JSP referenced from netscape to tomcat in tomcat's doc root behaves different than JSP in netscape's doc root. I got this result by changing the mime type for jsp to text/plain from it's default value of magnus-internal/servlet. Reverting the mime back to magnus-internal/servlet produces the same error 500 message. Changing the IE to display non-friendly errors did not shed any light on this. The only difference in logs for this is that when I revert back to the magnus-internal/servlet mime type, I get this in the netscape errors log: [02/Aug/2002:00:09:13] config (32160): for host XX.XX.XXX.XXX trying to GET /examples/jsp/snp/snoop.jsp, handle-processed reports: no way to service request for /examples/jsp/snp/snoop.jsp I don't get this error when I change the mime-type to text/plain. BEA suggests using text/jsp for integrating its application server. I tried that and got the same result after restarting netscape. I've even tried arbitrary values and got the same result. Finally, I removed the mime altogether--same result--no errors, but JSP does not execute and is hidden unless I source the page. Same thing. One other detail that may be important is that my linux machine has two NICS. One is a fixed external IP, and the other is a fixed local IP. My network is working fine, but I was just wondering if there are special configuration considerations for a multi-homed system. My guess is no, because most production applications I've worked on are multi-homed. # #Here is my makefile process: 1. Download tomcat 4.04 connectors source 2. copy the Makefile.solaris to Makefile.linux (which was not a part of the distribution, unfortunately) 3. changed references from SOLARIS and solaris to LINUX and linux 4. added SUITSPOT_HOME to /etc/bashrc 5. changed this line in the Makefile from: INCLUDEDIR=$(SUITSPOT_HOME)/include to: INCLUDEDIR=$(SUITSPOT_HOME)/plugins/include 6. created a links shell and gave it execute access: # vi links: ln -fs ../common/jk_ajp12_worker.o ln -fs ../common/jk_ajp13.o ln -fs ../common/jk_ajp13_worker.o ln -fs ../common/jk_connect.o # chmod +x links I had to do this because the references are not quite right in the Makefile 7. Then I ran the Makefile using gmake like this: # gmake -f Makefile.linux all It failed for references. I ran my links shell and reran make like this: # ./links # gmake -f Makefile.linux all That built nsapi_redirector.so.

RE: getRemoteHost(): how to get the fully qualified name?
There was an interface that was sorta usable from a programmatic standpoint. It was closed due to abuse. There are companies that sell a survey of the web relative to IP addresses and hostnames. I think that one of the products that Paul Vixies company sells has this, or did a few years ago anyway. Sorry that I can't recall more details. It's been a while. --- Shapira, Yoav [EMAIL PROTECTED] wrote: Howdy, See John Turner's response: it's not required for an IP address to have a host name associated with it. The reverse is true, every host name must have (at least one) IP address associated with it. So it could be the IP address you couldn't resolve doesn't have a hostname. Can you get a hostname for it using nslookup? If not, there's nothing one can do. The Arin/Whois approach is good for a human. However, it's not yet a public service API (AFAIK), so you can't use it programmatically which is what Mr. Li is looking for.

Howdy, You can convert IP to host name yourself. Here's the relevant section of the code: String ipAddress = 123.456.789.123; InetAddress ia = InetAddress.getByName(ipAddress); String hostname = ia.getHostName(); As you will by experimenting, the above has the desirable property of working whether ipAddress is nnn.nnn.nnn.nnn or the host name. So you can pass whatever you get from getRemoteHost() through this. The assumption you mention (the fully qualified name is available to the Solaris the server is running on) is important. The above will throw an UnkownHostException if the assumption is broken.

Re: tomcat 4.0.2 iPlanet Web Server 4.1 sp9
I have been doing a lot of work with Tomcat 3.x and the Nsapi redirector. Yes, it works. Your problem is probably one of configuration in obj.conf. It is VERY sensitive to ordering. In the default object you need to define ALL of the items being redirected prior to the default Ns handler. Please attach your obj.conf and I will take a look at it. And one of the things that I seem to recall from the documentation is to NOT use localhost, but instead use the FQDN (Fully Qualified Domain Name). --- Thierry Boucheny [EMAIL PROTECTED] wrote: Hello, I t seems like I am not the only one with this problem but I did not find any solution.

Re: configuring tomcat to run behind iPlanet Web Server...
Let me provide a few pointers. http://developer.iplanet.com/docs/technote/webserver/migratin.html The short story is to use the NSAPI redirector and AJP13. Configure the AJP13 Connection handler in server.xml. The redirector is typically included in the tomcat distribution. Though some folks have had a difficult time with getting it to build on Solaris. On the iPlanet side it's also fairly easy if you are doing simple stuff. --- Sesha Nandyal [EMAIL PROTECTED] wrote: How do I configure Tomcat to run behind iPlanet Web Server?

Re: Problems With POST Method
Just one datapoint. I haven't had any problems getting large datafiles to upload using POST. I've been working with test files in excess of 50MB. This is on Solaris 6 8, NT, and Win2K running against Java 1.3.1_03 and Tomcat 3.2.1. Though the most important aspect of this is the upload servlet that you are using.
