RE: Loggin out using JDBC realms
On Fri, 31 Aug 2001, PHAM,TAM (HP-Vancouver,ex1) wrote: Regarding logging out of JDBC realms. This does not seem ideal if I have to explicitly call session.invalidate() when the user logs out. Tam, You can use javascript to fire session.invalidate() in case the user closes browser window (ie. does not use you log-out link). And regarding automatic expiration after given period of time you should be able to put following in your web.xml: session-config session-timeout30/session-timeout !-- timeout in minutes -- /session-config If you want to run your own code in case of automatic session expiration then I hope this article helps: http://w6.metronet.com/~wjm/tomcat/2001/Jan/msg00703.html with best wishes, Taavi
How to access X509 Certificate?
Hey all, I'm trying to access the certificate that the user has sent to authenticate himself. I'm using the Tomcat/Apache combo. Apache correctly exports the Certificate to the SSL_CLIENT_CERT environment variable, but when I try to read javax.servlet.request.X509Certificate, Tomcat always returns null. The list of attributes is always empty. I've uncommented JkHTTPSIndicator HTTPS, JkSESSIONIndicator SSL_SESSION_ID, JkCIPHERIndicator SSL_CIPHER, JkCERTSIndicator SSL_CLIENT_CERT and set JkExtractSSL to On. I'm sure the Ajp13 protocol is used since I've disabled everything else. What am I missing here? Any help greatly appreciated! Thanks in advance, Christoph.

RE: howto mirror a jsp site.. convert ?/= to .do/param1/param2?
Hi Pier -- Sorry I guess I wasn't clear... getting the file with wget works fine.. all I do is: wget -m fullscreen.com But, what I get is a bunch of myfile.jsp?param=value files. moving this directory into apache doesn't work, b/c when the user requests the file /myfile.jsp?param=value apache looks for myfile.jsp, doesn't find it returns a 404. So, I'm wondering, is there some way to rewrite the param / values so that JSP understands them so that apache doesn't attempt to strip them away as parameters? I've seen struts apps other pages use this format: myfile.jsp;param=value I know that I can use servlet mapping to do something like myfile.do;/pathto/myfile.jsp;param=val;param2=value have the servlet servicing myfile.do rewrite the URLs into standard format. Perhaps thats what I'll do. I was just wondering if there is some way to get tomcat to do this automatically for a webapp. Thanks again- Matt FullScreen Delicious downloadable desktop delights WGET works for me... Just be sure to escape that ? character in the query string... Do something like (quoted) # wget http://mysite.com/myfile.jsp?param=value; Or escaped: wget http://mysite.com/myfile.jsp\?param=value
Segmentation Fault when modifying classpath?!
Ok...
All this surrounds modifying tomcat.sh per install instructions found in
apache-soap.
Per Apache-Soap's Getting Tomcat Ready, I have changed my classpath to put
xerces.jar at the beginning of my classpath as follows:
unset CLASSPATH
CLASSPATH=/usr/local/java/lib/xerces.jar
for i in ${TOMCAT_HOME}/lib/* ; do
if [ $CLASSPATH != ]; then
CLASSPATH=${CLASSPATH}:$i
else
CLASSPATH=$i
fi
done
...
When starting tomcat I get the following:
Using classpath:
/usr/local/java/lib/xerces.jar:

Unable to start tomcat 3.2.3 (Security related problem)
Hello, I have downloaded tomcat version 3.2.3 source code and compiled it on my windows 95 machine with Sun JDk 1.3.1. I also had to download JSSE because there was no option to compile without ssl support. If these classes are not in classpath then source doesn't compile. My problem is when after compiling distribution when I try to start tomcat following errors is produced: /// FATAL Configuration error: java.lang.SecurityException: sealing violation .. .. I have followed that steps provided in SSL howto about making entry in java security file and using keytool. For password it is written that password can be changeit but when keytool asks about alias tomcat password what should be entered. (i.e. what is the tomcat admin password). Please help me in solving above problem because I am unable to start tomcat. Is there any option to compile tomcat without ssl support?

finding sun.tools.javac.main?
PLEASE can someone help. I'm running the JDK1.3 and Tomcat 3.2.3. All the examples compile but, when I try to call up a simple JSP page, I get an error that it can't find sun.tools.javac.Main. I have C:\JDK1.3\LIB\TOOLS.JAR in BOTH the classpath and in the path (for Win 98) set in the autoexec.bat. I hunted down the 'offending' call and found this in SunJavaCompiler.java: import sun.tools.javac.Main; /** * The default compiler.

Re: [TC3.3b1] use of taglib causes org.apache.crimson.jaxp.DocumentBuilderFactoryImpl not found error
I have made the changes suggested. I still get the same errors.
The jsp file will work when referenced directly,
http://localhost/jetspeed/hello.jsp, but fails when it is executed by
Jetspeed.
This problem is does not occur in Tomcat 3.3-m4 or Tomcat 4.0-b7. I
suspect something that was changed between 3.3-m4 and 3.3-b1 is causing
the problem, but I do not know what it is :-(. I do not believe the
problem is with Jetspeed because I used the same WAR file when testing
all 3 versions of Tomcat.
The error message may not be related to the actual error. The empty
.java file in the work directory may be the closer to the problem.
Maybe somewhere in the process of converting from .jsp to .java when a
taglib is defined.
I enabled debug logging.
No entries on the servlet logfile
The jasper log contained:
2001-09-01 17:29:25 - Package name is:

Tomcat and Input-Output streams
Hello again:
Searching a little bit more I've founded the solution to my problem.
Relying reading of the properties file to a PropertiesManager class with a
method like:
static {
try {
Class propertiesManagerClass = PropertiesManager.class;
ClassLoader classLoader =
propertiesManagerClass.getClassLoader();
InputStream inputStream =
classLoader.getResourceAsStream(PROPERTIES_FILE);
properties = new Properties();
properties.load(inputStream);
inputStream.close();
} catch (Exception e) {
System.err.println(Error loading properties from file
+ PROPERTIES_FILE + : + e);
e.printStackTrace();
}
}
everything works fine. My question now is, why? and, where can I get some
information about Tomcat and the IO files? I realized that Tomcat writes
my database log file to /etc/init.d/ (where the tomcat startup script
is) I guess that with my previos implementation Tomcat searched for the
bd.properties file in that same directory. Why Tomcat behaves like
this? How can I control the exact location of my IO files?
Thanks a lot,
Quique

I use the startup.sh and shutdown.sh scripts to start and stop tomcat. If i stop tomcat and then bring it back up and go and try to view a servlet I get an internal server error from apache, like tomcat really isnt up yet or something. But if i then hit refresh on my brower like 7 or 8 times tomcat will start responding like normal. I saw a message on the same topic of this in the mail archives but I didnt see a definite answer. Anyone know why this is? And is there any way to stop this? Without details of the server components you are running (Apache version? Tomcat version?) and the actual servlet being tested, and the *actual* error messages and/or stack traces you are receiving, it is impossible for *anyone* to give you any substantive help on this. Second question is about auto reloading. I use ant to create my war files so they are of the standard directory layout. After tomcat starts and unpacks the war I should be able to copy recompiled classes into the MyProject/WEB-INF/classes directory and have tomcat auto reload (server.xml says that auto reload is default to true ) This works most of the time. But sometimes i swear it wont reload my servlet until i stop tomcat, remove the unpacked war directory and restart tomcat. This doesn't make any sense to me? What Tomcat are you running? Tomcat 3.2.x has lots of problems recognizing updated classes that are not themselves servlets -- Tomcat 4.0 fixes this particular issue. Also one last semi related question. Can someone tell me how tomcat decides what servlets to cache in memory? *All* Java classes that are your servlets (or are referenced by your servlets) are loaded once by the appropriate class loader. This is a Java thing, not a Tomcat thing. If it is really auto reloaded servlets, if i delete all my class files i shouldnt be able to get to any servlets correct? No. If you have referenced a particular class *once*, it will have already been loaded into the JVM. The existence or non-existence of the .class file where this class was loaded from is not relevant. But i have deleted all my class files and still can get to certain servlets in my web app. So how does tomcat choose what servlets to cache or not? Any and all information that can help with these three questions would be greatly apprecaited. Thanks in advance. Scott Knight Craig

Re: Logging
Tomcat 3.2 does not create access log files in the format required for tools like WebTrands. You will need to do one of the following things: * Run Tomcat 3.2 behind a web server like Apache (which will create such log files for you). * Run Tomcat 4.0 in stand-alone mode (which will create such log files for you).

I would like a to keep a track of all IP's coming into my machine, all pages visited, etc. I am going to use WebTrends to analyze the logging information and put into report form. The question I have is, how would I go about doing this. The two logs I have seen, jasper.log and servlet.log do not give me any real good statistics. Remember I am not a developer so I have no clue how to do this. I am running Tomcat 3.2.3 on Solaris 8. Thank you very much for your help!! Amit Anand [EMAIL PROTECTED]
Re: Security question

Security constraints that you mention in your web.xml deployment descriptor are *only* applied to the original request URI, *not* to any request URI that is included by your servlet or JSP page. That is by design. If the content from a particular include should not be displayed to a particular user (because they don't have a required role), you should not be doing the include in the first place.

Re: urgent : using Mail Resource in web.xml
Can you try putting mail.jar into common/lib? That way, it is available to both the Catalina internal classes (including the resource factory) and your web app?

Is there a Servlet spec-compliant way to get the webapp's directory's path programmatically, from within a servlet? No. getServletConfig().getServletContext().getRealPath(/); Of course it won't work within a .war file.. Something like calling ServletConfig.getInitParameter(docBase), but something that's standard, and that does not require me to specify the path explicitly in a configuration file? You are starting from an incorect assumption, that there *is* such a thing as a portable directory path to a web application. It is entirely legal for a servlet container to run a web application directly from a WAR file (in which case there is no expanded directory), or by storing its static resources in some other sort of structure (such as being BLOB objects in a database). Most websites are not static. Users publish content, for example, and the logical place for that content to be stored is on the filesystem inside the webapp, not in a database. So for many, or not most, websites, the notion that a website can be kept in a .war is not practical. I'd be interested to know if there is a solution to this. Perhaps the filesystem could be mapped to a JNDI context, which could be made into a virtual filesystem inside the webapp? --Jeff TIA, Rick Craig McClanahan
