Problems installing Jakarta Isapi Redirector
Hi, I'm trying to install and configure Jakarta Isapi Redirector on a Windows Server 2003 machine with IIS 6.0 and many ASP.Net web sites deployed and working on it. Also, this server redirects some URLs to a J2EE application deployed under WebSphere 6.0 (using a ISAPI filter) that is installed on a different server. I'm needing the redirection because my workgroup is developing a J2EE application that will be deployed on a different machine with Windows Server 2003 and Apache Tomcat 6.0 installed. When I configure the redirector (configuration files workers.properties, uriworkermap.properties, virtual directory in IIS (jakarta), registering the ISAPI Module, allow execution of ISAPI filters in IIS) and i'm trying to enter to the mapped URL in a browser, the response from the IIS Server is an Internal Server Error (500 Error), but i don't know what's the reason of the problem. I tried to view the logs but there are no related information about the error. I tried mounting 3 different scenarios, with sucess: 1. A machine running Windows XP and Tomcat 6.0 (with the deployed application), and another machine running Windows XP and IIS 5.0 (using the Jakarta Redirector). 2. A machine running Windows Server 2003 and Tomcat 6.0 (with the deployed application), and another machine running Windows XP and IIS 5.0 (using the Jakarta Redirector). 3. A machine running Windows Server 2003 and Tomcat 6.0 (with the deployed application), and another machine running Windows Server 2003 with IIS 6.0 (using the Jakarta Redirector as the only ISAPI Filter installed). The second machine had only one ASP.Net application running on it. So, I'm thinking that the problem is related with the use of WebSphere ISAPI Filter and Jakarta ISAPI Redirector at same time, but i wish to know what is the reason of the problem, and if exists a solution for that. Any help would be appreciated. Thanks. Carlos.
Vista woes....
hi, am trying to get Tomcat to run in Vista, have dl'd and installed Tomcat 5.5.23 set necessary vars thus: JAVA_HOME=C:\Java\jdk1.5.0_12 JRE_HOME=C:\Java\jdk1.5.0_12\jre but when try to run a webapp I get a 404 (even tomcat-docs doesn't run..) I know how to set up Tomcat, have done it before.. I'm wondering if I'm missing anything, but apart from setting up these two env vars I can't think of anything else right now... (path to compiler is set correctly, I can compile stand-alone classes..) for Tomcat I have set CLASSPATH thus: set CLASSPATH=.;apache-tomcat-5.5.23\common\lib\servlet-api.jar;apache-tomcat- 5.5.23\common\lib\jsp-api.jar (usu., at the advice of folks in the java group, I don't set classpath, and never have problems.. but set it now to see if it would help.. Tomcat is not compiling any JSPs, when I go to 'work' dir there are no src files or classes for the JSPs..) thank you.. - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: accessing files/dirs.....
yes I know, eventually I want to do this whole webapp in struts.. for
now just want to be able to count how many images in 'images' folder..
(what I don't get here is first line.. where does the reqParameter come
from? (this method is usu. used to get params from request (user input,
query string, etc..) so don't get where directory is coming from here..)
thank you very much..

Re: accessing files/dirs.....
ok, I asked webhosting guy, this is what finally worked:
/chroot/home/myuid/mydomain/tomcat/webapps/india/delhi/images
:)
many thanks for yr help...

What I posted was an excerpt from a jsp page writing the index of a
folder -- no Struts in sight. directory was just an arbitrary request
parameter for example purposes:
http://localhost:8080/myWebApp/imageList.jsp?directory=%2fsome%2fdirectory
It doesn't really matter how you get that string. In your case, you
don't even need the for loop -- just write the count or store it in the
pageContext for later use in a tag like c:out value=${fileCount} /
For getting the count of files, just replace the contents of the if
(dirFile.isDirectory()) block with this one statement:
pageContext.setAttribute( fileCount, dirFile.list().length ) ;
And then you can write it out later using the c:out tag as above or
%=pageContext.getAttribute( fileCount )%

downloading JSTL..
hi, am a bit confused about JSTL.. when on this pg, http://jakarta.apache.org/taglibs/doc/standard-doc/intro.html it says, about half-way down, Download the Standard Tag Library Release from an Apache Jakarta Project Mirror when I click on Apache Jakarta Project Mirror I get taken to http://jakarta.apache.org/site/downloads/index.html don't know what I'm supposed to download from this page... I click on taglibs get taken to a page with yet another long list.. http://jakarta.apache.org/site/downloads/downloads_taglibs.html.. what do I download here?

I thought JSTL meant all taglibs in one package.. From that page you either want Standard 1.0 or Standard 1.1, depending on what version of JSTL you want to use (which depends on what version of the Servlet spec you're configuring your webapp for.) In general, Tomcat 5 - Servlet 2.4 - JSTL 1.1 Tomcat 4 - Servlet 2.3 - JSTL 1.0 (However, Tomcat 5 can run apps written to earlier versions of the servlet spec, so check your web.xml to see what version you're *really* using.) And no, JSTL isn't all the taglibs, it's the Standard taglib and there are lots of other ones, as you can see from that page. (And those are only the ones distributed by the Jakarta Taglib project.) HTH, yes, that helped, thank you very much...

I want to be able to run it as a stand-alone server, just like I did in Windows 2000.. thanks again.. David Smith wrote: Can it be installed on Win 2003 Server? Yes. Can't find any ref's?
