Form based authentaction but not for static resources
Tomcat fans, I have a (I assume basic) question wrt servlet/tomcat authentication/authorization First let me indicate I would like my URL to always be something like http://host/username I have configured a security-constraint like security-constraint web-resource-collection web-resource-namemyapp/web-resource-name url-pattern/*/url-pattern http-methodPOST/http-method http-methodGET/http-method /web-resource-collection auth-constraint role-nameuser/role-name /auth-constraint /security-constraint I would however like to have some static resources accessible without any authentication. Typically these would be identified with http://host/resouce/appstyle.css etc. The reason is that I would like to have the login page use an external stylesheet and/or some images. Is that at all possible? Any guidelines how to achieve that?

RE: Multi processor issue
Can you suggest a fix? I'm not sure how this kind of thing could be safely veto'd... for instance, it might actually be appropriate for a RequestDispatcher to be re-used in some context (say, repeating a request twice) or even to do so with different threads, as long as the access is done strictly serially. Do you mean submittingan enhancement request with some proposed code? Fantastic! I'm glad we were able to help, even if it did take a while. Yes and I want to thank all the people from the mailing list for their good advices and also for giving me additional motivation to investigate further.

Re: Multi processor issue
Caldarale, Charles R wrote: Since query information is normally unique to a request, I think the above could be construed that the RequestDispatcher is cognizant of the query string. If so, each RequestDispatcher would be associated with a specific request. I agree that the RD is cognizant of the query string but I don't see that this prevents the RD from being re-used. The RD merges its query string (specified on creation) with the query string of the request passed to the include/forward method. No reason it can't do this several times. SRV.15.2.8 ServletContext, getRequestDispatcher(String): The resource can be dynamic or static. Since dynamic resources can come and go and their existence can be dependent on specific requests, there is an implication that a RequestDispatcher is associated with the request it has been created for. I see where you are coming form here but this strikes me as an application issue. Send lawyers, guns, and money. (That's not in the spec, but perhaps should be.) He he. Indeed! What does it for me is: a) that you can obtain an RD from the context; b) SRV.8.1 that states: The method uses the path to look up a servlet ... wraps it with a RequestDispatcher object, and returns the resulting object. In my mind this aligns RDs more with servlets than requests. I plan to look at modifying the current RD code over the holiday.

Re: Re-executing a servlet request
You won't be able to re-compose the request object as if it was just
submitted. The quickest, dirtiest way is to just stow the form params
in the session upfront and then use them from the session later.
Example:
c:if test=${not empty param.mySubmitBtn}
c:set var=mySessProp scope=session value=${param.myFormField} /
c:set var=mySessProp2 scope=session value=${param.myFormField2} /
!-- Keep going though all the form fields you want to save. --
/c:if

Re: Re-executing a servlet request
Yes. I'm saying the original request won't be available. One other
alternative I can think of is for the last page submit to add all the
saved params to the request for page 1. Last page example form tag:
form action=page1.jsp?frmParam1=valuefrmParam2=value

Are you saying that I can't build a request and execute it directly,
and therefore will need to check for the stored parameters on the page
that I'm re-opening?
Example:
c:if test=${not empty param.mySubmitBtn}
c:set var=mySessProp scope=session value=${param.myFormField} /
c:set var=mySessProp2 scope=session
value=${param.myFormField2} /
!-- Keep going though all the form fields you want to save. --
/c:if

I've been trying to do this with sessions, but can't figure out the

SOLVED - Re: Desperate: Tomcat 5.5. j_security_check
Hi guys, first of all: Thanks to all of you for your help! We got it (JDBC-REALM) working now, however, it was a long way. The resolution in short words: We installed a vanilla JDK 1.5 from SUN plus a vanilla Tomcat 5.5 from Apache, same error occured, empty string in the query for j_username in the MySQL-logs I decided that it had either to be the jdbc-driver (Connector/J) or the database since the logs showed me that j_username was read properly from j_security_check. Then I decided to dump MySQL 4.1.11 (we installed it from the MySQL-distri) and we re-installed MySQL 5.0.30 and currently are using connector/J 3. Aand: Voilà! It's working now. Therefore, if any of you guys is planning to run Tomcat 5.5 with Debian Edge and you want to use the facility of j_security_check, keep to Debian's scource-tree and install MySQL 5.0.30 via aptitude, it will save you a lot of work.

dedicated servlet connections
Hi all, sorry for reposting. I posted the original message before I completed registration, so I am not sure if got through. I have two servlets: Worker and Status. Worker servlet gets hit very frequently and consumes all available Tomcat threads (configured via maxThreads). Thus, whenever I try to access the Status thread I have to wait a long time. Is there a way to either dedicate some threads to Status servlet or set Status servlet priority higher than Worker servlet so that I can access it faster? Note that both servlets need to work in the same Tomcat instance. Thanks. Alec
Question about http connections
Hello there! We have a Jboss 4.0.1 server, and we're experiencing a strange connector behavior (might be our app as well). We check the connections on the connector 8009 (we use a mod_jk behind jboss). And we have some requests on Service status that have over 14.000 seconds. We even killed the remote user browser (its an internal user from our corporation) but the connection is still used, it takes a few minutes to it to die. We have this behavior in many other requests in different parts of the system, and many with over 100s of time. What could be causing this? Any thoughts?

Re: dedicated servlet connections
You can configure two connectors with associated pools. If you need to talk to both parts of the app under the same name and port, you can front those two connectors (ports) with apache/mod_jk. With a sufficient recent version of mod_jk you can configure several workers to forward to different connectors on the same tomcat (you'll only need a recent version, if you want to combine this with load balancing. Earlier versions required the workers name to be equal to the jvmRoute of tomcat, so you could only use one worker per tomcat target. Now we have a route attribute). JkMount /myapp/perf/* perf_worker JkMount /myapp/status stat_worker and in workers.properties: worker.list=perf_worker worker.perf_worker.port=8009 ... worker.list=stat_worker worker.stat_worker.port=8010 and in server.xml use two Connectors with ports 8009 and 8010 with different thread counts. This will not use priorities though. Also: you could get the same thread exhaustion problem on the apache layer. Regards, Rainer Alec Swan schrieb: Hi all, sorry for reposting.

Re: dedicated servlet connections
Rainer, we are not using Apache web server. Instead, HTTP requests get sent directly to the servlets in Tomcat. We do, however use the (hardware) load balancer. Is there a way to just configure Tomcat to allow some servlets have higher priorities than others or dedicate a pool of connections to them? Thanks.

Re: Helping setting appropriate prefix when using ServletContext.getResourceAsStream()
Dear Chuck Caldarale Others, Thank you for your response! Chuck - Your e-mail was very informative... I did remove the servlet-apis from my %CATALINA_HOME%/mywebapp/%WEB-INF/lib directory. The only reason I had it there was because I use Eclipse for development and its easier to configure the build path by clicking on Add Jar rather than clicking on Add External Jar. But I took your advice and removed it and now use Add External Jar. Here's my situation... I changed my Ant build script to move the log4j.properties file into my WEB-INF/classes dir. Also, my log4j-1.2.9.jar gets moved inside my WEB-INF/lib dir. But for some odd reason, when I run Tomcat, it doesn't seem to know where my log4j.properties file is! My Log4jInitServlet seems to have the path wrong!

Most of that was irrelevant :-) but the above doesn't mesh with your
earlier path:
C:\DevTools\tomcat\jakarta-tomcat-5.5.9\mywebapp\WEB-INF\classes\log4j.properties.
:: which doesn't include a 'webapps' directory.
Is that just a typo or are you setting Context atttributes (like docBase)
somewhere else?

System path being ignored when using Tomcat Windows service?
Hi all, I have a web application that uses Runtime.exec() to start a process. The process that I'm starting is in the system path. The application works fine if I'm running the Tomcat platform independent package. However, if I use the Tomcat Windows service, it appears that the process can't be created because it can't be found. It works if I specify the fully qualified path the the executable, but, I want to use only a relative path. I'm wondering if the fact that it appears to be ignoring the system path has to do with the fact that it's a Windows service, or, if it's an issue with Tomcat? I'm running Tomcat 5.5.20 with Sun JDK 1.5.0_10 and Windows XP SP2. Also, I noticed that if I change the user account that the Tomcat service is supposed to run as using the system tray applet, it doesn't change the settings, it just keep reverting back to LocalSystem. Has anyone else ran into either of these issues. As far as I can tell, the second issue looks like a bug. Also, I tried setting java.library.path using the applet, but, that didn't seem to help.

How to load XML config file properly from WEB-INF?
Hi,
If you've been following my previous posts, you'll notice that I had a
problem of trying to load a properties file (stored under WEB-INF),
until I edited my build script and made it place the log4j.properties
file under WEB-INF/classes, and then used the following code to load
in the properties file:
public class Log4jInitServlet extends HttpServlet {
public void init() throws ServletException {
Properties props = new Properties();
try {
props.load(this.getClass().getClassLoader().getResourceAsStream(/log4j.properties));
} catch (IOException e) {
e.printStackTrace();
}
}
Although, this works for loading property files into my webapp's
CLASSPATH, my new question (just for those who think that I am trying
to post the same question twice, which I am not), is this:
I also have a servlet which uses init params to load parse XML
config files (which are located under: %TOMCAT_HOME%/mywebapp/WEB-INF/
)
My new question is:
How do I use the getResourceAsStream() method to load this particular
XML file which is not located under WEB-INF/classes? Its located under
just WEB-INF.
Also is there a way to convert this InputStream into a File?
Here's my original piece of code (which works when
undeployWars=true, I am trying to get it to work when
undeployWars=false):
public class XmlConfigInitServlet extends HttpServlet {
public void init() throws ServletException {
// String prefix = getServletContext().getRealPath(/);
String file = getInitParameter(xml-config-file);
File xmlConfigFile = new File(prefix + file);
if (!xmlConfigFile.exists()) {
System.out.println(attributes-config.xml not found,
+ xmlConfigFile.getAbsolutePath());
}
try {
// Configure Digester from XML ruleset
AttributeBeanXmlConfigHelper.parse(xmlConfigFile);
Logger.getLogger(this.getClass()).warn(Finished
parsing the
config file.);
is.close();
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
What I thought I could do was something like this inside the try / catch:
InputStream is =
getServletContext().getResourceAsStream(WEB-INF/attributes-config.xml);
// Configure Digester from XML ruleset
AttributeBeanXmlConfigHelper.parse(xmlConfigFile);
Now, the problem is... I think that there will be definitely be a
pathing issue for WEB-INF/attributes-config.xml when using
getResourceAsStream() (I am guessing because of my attempts with the
Log4jInitServlet postings). Also, how would one convert an InputStream
to a File?
e.g
How to convert is and xmlConfigFile?
Cheers,
JD

Re: System path being ignored when using Tomcat Windows service?
I think it must have been a permissions problem. I switched to using a different account and now it works. The systray applet doesn't work.

James,
James Dekker wrote:

You'll want to use the method ServletContext.getResourceAsStream(). From
the javadoc:
This method is different from java.lang.Class.getResourceAsStream, which
uses a class loader. This method allows servlet containers to make a
resource available to a servlet from any location, without using a class
loader.
The CWD should be your webapp's directory (in your case,
%TOMCAT_HOME/mywebapp%). You'll want to use the path /WEB-INF/my.xml.
Also is there a way to convert this InputStream into a File?
No. If you want more than just the bytes from the file, you'll need to
use ServletContext.getResource(), which returns a URL.
Here's my original piece of code (which works when
undeployWars=true, I am trying to get it to work when
undeployWars=false):
public class XmlConfigInitServlet extends HttpServlet {
public void init() throws ServletException {
// String prefix = getServletContext().getRealPath(/);
String file = getInitParameter(xml-config-file);
File xmlConfigFile = new File(prefix + file);
if (!xmlConfigFile.exists()) {
System.out.println(attributes-config.xml not found,
+ xmlConfigFile.getAbsolutePath());
}
I'm sure that you don't have that one line commented-out, otherwise this
code does not compile. Assuming that prefix is defined as indicated
above, then this will certainly work when unpackWars (undeploy?) is set
to true, as you are building a filesystem path and loading a file as
usual.
When your file is still inside a WAR, you're not going to be able to
find it using a File object. You either have to get clever and try to
load the file out of the WAR file by actually opening the WAR file and
searching for the file (bad, and a waste of time to boot), or just by
using the built-in helper method like this:
public void init() throws ServletException {
ServletContext application
= getServletConfix().getServletContext();
String filename = getInitParameter(xml-config-file);
URL xmlConfig = application.getResource(filename);
if (null == xmlConfig) {
System.out.println(attributes-config.xml not found,
+ xmlConfigFile.getAbsolutePath());
}
else
{
InputStream in = xmlConfig.openStream();
// Hope a java.io.File argument is not necessary
AttributeBeanXmlConfigHelper.parse(in);
in.close();
}
What I thought I could do was something like this inside the try / catch:
InputStream is =
getServletContext().getResourceAsStream(WEB-INF/attributes-config.xml);
// Configure Digester from XML ruleset
AttributeBeanXmlConfigHelper.parse(xmlConfigFile);
Now, the problem is... I think that there will be definitely be a
pathing issue for WEB-INF/attributes-config.xml when using
getResourceAsStream() (I am guessing because of my attempts with the
Log4jInitServlet postings).
Did you actually try it? It's supposed to work this way.
Also, how would one convert an InputStream to a File?
You can't: a java.io.File is a filesystem notion, and an InputStream is
just a source of bytes. If you had an InputStream that came from an HTTP
connection, what would it's java.io.File object look like?
The most portable way to do it would be to read the bytes from your
source file in the WAR and write them to a temp file in the TEMP
directory or something like that.
Why doesn't your class allow configuration through something other than
a java.io.File object? Can you change that?
