unsetting bean w/ session scope
i use a bean with session scope in all of my JSPs in a particular app i'm working on by using the following: jsp:useBean id="name" class="Name" scope="session"/ however, i've need to reset this particular bean at some point...i tried this by running the following: name = new Name(); this did not work...is there any workaround to restore a bean w/ session scope back to it's original state? thanks!

RE: unsetting bean w/ session scope
what about creating a instance of the class of the bean. so st like : Name tempClass = new Name(); then call all the setters on the existing bean with the getters on the bean. name.setXXX(tempClass.getXXX()); ... and so on.. afterwards set tempClass back to null : tempClass=null, so it can be gc-ed. better write a globalset/get for your class, then you can use : name.setAll(tempClass.getAll()); hope this helps greetz Dennis -Original Message- From: Kris Gonzalez [mailto:[EMAIL PROTECTED]] Sent: Monday, April 02, 2001 8:22 AM To: [EMAIL PROTECTED] Subject: unsetting bean w/ session scope i use a bean with session scope in all of my JSPs in a particular app i'm working on by using the following: jsp:useBean id="name" class="Name" scope="session"/ however, i've need to reset this particular bean at some point...i tried this by running the following: name = new Name(); this did not work...is there any workaround to restore a bean w/ session scope back to it's original state? thanks!
Namespace clarification
Hi, I am using TOMCAT 3.2. I am trying to transform an xml doc with XSL to generate a HTML. When i write a simple Java Class and use xerces, xalan it works just fine. When written in JSP using JAVA, When i call the page i am getting the following error "Namespace not supported by SAX Parser". I think Tomcat uses SAX Parser. How to come around this problem. I am using namespaces. Is there any option, to plug in XERCES parser with TOMCAT, if so how to do it. Since XERCES supports namespaces could this be a option to come around this problem? Please help.

[CATALINA]
Using the latest CVS of Catalina, I am having an issue with my web application. When I build my webapp with Ant, I create many xml files under WEB-INF/classes/xml/oem/*. Then when a request comes in, I use getClass().getResource() to return the URL to the xml file. In Tomcat 3.x (3.0,3.1,3.2,3.2.1), the URL returned looks something like file:///opt/tomcat/webapps/app-name/WEB-INF/classes/xml/oem/file.xml In Catalina, the URL returned is: /WEB-INF/classes/xml/oem/file.xml The problem is when I use this URL as an InputSource to my XSLT processor (Saxon), which is contained in /WEB-INF/lib/saxon.jar, it says that it cannot find the file. In Tomcat 3.x, it finds the file fine and continues processing. Any suggestions? Is this a bug? Undefined behavior? Is there a workaround? Thanks, Scott Sanders
Re: Namespace clarification
tomcat puts together the classpath dynamically and you have no way of influencing the order it does so. so the sax parser might me loaded before xerces. one way to get around this is to edit the tomcat.bat and change the dynamically setting of the classpath to statically setting the classpath and taking care that xerces.jar is at the beginning. you might also want to check out the cocoon project as this provides the functionality of what you are trying to do. it also allows you to create XSP pages (hybrid of JSP and XML)the url is xml.apache.org. hope this helps christian --- "Prasanna.N" [EMAIL PROTECTED] wrote: Hi, I am using TOMCAT 3.2.

Tomcat SSL Equifax
Hi, Has anyone had success installing an Equifax certificate on Tomcat (3.2.1) ? These come as a certificate chain. I can load the certificate for the machine and the equifax certificate into the keystore, and these appear correct (or atleast I can list and see the details of them using the keytool -list command). When I use the keytool command to generate a self-signed certificate (alias tomcat) the SSL server works. However when I delete that and use the machine certificate (again aliased to tomcat), my browser (IE4) complains that it does not understand the response stream. Tomcat appears to start correctly and I can find no errors in the log files. Cheers Hugh

Has somebody build a CDROM Project with Tomcat? We try to use it as a web- and servlet server on a CDROM. Now there is the problem with the write access by tomcat (auto.conf files, log-files a.s.o.) My questions: 1. How to stop tomcat from generating the auto-conf files in bin-directory? 2. Can I point to conf files (server.xml, web.xml) on a temp dir on harddisk with write access? 3.

security provider problem with tomcat
hi there! i'm trying to make cryptix security work with tomcat. the installation guide says to register the security provider with the jre 1.3 (which i did). the installation was successful and added the following lines to java.security # Added by Cryptix V3 installation program: security.provider.3=cryptix.provider.Cryptix now, when i run a example batch (without tomcat), it works perfectly. but when i call the same method (the one that uses the encryption) from a jsp file, i get a error on the tomcat saying: NoSuchProviderException: Provider Cryptix not available whats the problem here ? i already made sure that i start the tomcat with the same java.exe i used to register the security provider. first i had the cryptix.jar in the web-inf/lib of my webapplication... then i thought apparenty tomcat is missing the jar and put it to tomcat/lib (restarted tomcat) but it didnt help. so either way, the cryptix library _is_ in the classpath, so what am i missing ? thanks in advance! greetings, lukas

Re: Tomcat SSL Equifax
It's working for me. I'm not sure from your note whether you did the same thing, but what I did is to load the "certificate" (really a chain of two certs) for equifax into cacerts and then load the certificate for my site into the keystore used by tomcat. This left the keystore holding a chain of 3 certificates (the three mentioned above) under the alias "tomcat". Hope this helps, Mike

RE: load balancing and synchronization
Synchronization does only work per-JVM. (Consider that you're synchronizing on an object: that same object cannot possibly appear in two different JVMs.) The only work-around is to do locking yourself, using some resource (like a file, a database, a servlet, or an RMI server) which is accessible from all server machines/processes. -- Bill K. -Original Message- From: Nico Wieland [mailto:[EMAIL PROTECTED]] Sent: Monday, April 02, 2001 8:40 AM To: [EMAIL PROTECTED] Subject: load balancing and synchronization hi list if i do load balancing with tomcat (w/ mod_jk), what happens if the two tomcat servers at the same time execute a synchronized method? will they know that they mustn't execute it concurrently or not? if synchronization worked only per JVM, would there be a workaround? thanks, -nico Nico Wieland NETVERTISING AGAgentur fuer zeitgerechte Kommunikation Samariterstrasse 5, CH 8032 Zuerich Telefon +41 1 267 11 11, Fax +41 1 267 11 99 mailto:[EMAIL PROTECTED] http://www.netvertising.ch

Beginner question
Hi, I just installed Tomcat, and set the TOMCAT_HOME and JAVA_HOME environment variables in profile, when I export them and try to run startup.sh it is no go. I get an error message that says there is no such directory /usr/java/jdk1.3/bin/bin/java . If you take the /bin/java off the end you have my path for the JAVA_HOME, but I do not get where the concatenation of the last portion is coming from. If I do not export the variables and run startup.sh it guesses the TOMCAT_HOME and runs fine. Any suggestions? Thank you all in advance. New to Linux

Re: How to re-use a request scope bean?
Joe, I still haven't had a chance to try this yet, but I wanted to let you know that this seems like the right way to go and I appreciate the suggestion. - Todd Chaffee At 02:02 PM 03/21/01 -0800, you wrote: The ideal would be for me to be able to pass the existing request's bean to the new request. Is this possible? Short of trying to serialize the object and encode it into the URLs on the page, I don't know of a way of getting a request-scope object to survive outside of the scope of the request (go figure!). I think my first try would be to write a "container" bean that would hold all search results (either in the application scope or the session scope). Whenever someone wanted a new search, the search container would handle the process of making a new SearchResults object and it would merely pass back some identifier that you could use to get it later: jsp:useBean id="searchmanager" scope="session" class="mypackage.SearchManager"/ ora:useProperty id="mysearchresults" name="searchmanager" property="newsearch" arg="hot teenage lesbian sluts" class="mypackage.SearchResults"/ !-- useProperty is a tag that appears in O'Reilly's "Javaserver Pages". It's for beans that can return other beans as properties. In this case, the searchmanager.getNewsearch(String arg) method returns an object of type mypackage.SearchResults. useProperty calls this method and assigns the returned bean to "mysearchresults". You can probably download O'Reilly's implementation of useProperty, or you can brew your own. -- jsp:forward page="product_list.jsp?searchid=%= mysearchresults.getId() %" \ Then, in your product_list.jsp, you'd have something to recall the results based on their ID something like: jsp:useBean id="searchmanager" scope="session" class="mypackage.SearchManager"/ ora:useProperty id="mysearchresults" name="searchmanager" property="existingsearch" arg="%= request.getParameter(\"searchid\") %" class="mypackage.SearchResults"/ Let me know if this helps, - Joe

j_security_check problem with embedded Tomcat 3.2.1 on Widows 2000 with IIS 5.0
Hi, I am trying to use IIS 5.0 web server on Windows 2000 with embedded Tomcat 3.2.1 running in JBoss. I followed the instructions in "Tomcat IIS How To" and I am able to see the login page. Once after typing in the login information, I am getting j_security_check error. Somebody has suggested on this mailing list that I need to register ".class" , ".jsp" etc. extensions to be forwarded to Tomcat using isapi_redirect.dll in IIS console. I did this too. It appears that I might be missing some of these forward requests to be registered in IIS console, that's why I might be having j_security_check. So could you please help me on this. "Tomcat IIS How To" instructions worked perfectly on IIS4.0 on NT, but these are not working properly Windows 2000 with IIS 5.0. Regards, Rao

Keepalive connections in Tomcat ???

So my question is if Tomcat supports connection keep alive and if there is anyother way to support persistent connections in the above scenario. thanks deep _ Get your FREE download of MSN Explorer at http://explorer.msn.com
FW: tomcat-user : tomcat 3.2 returning partial page
Hello -
We're currently having a problem w/Tomcat not returning the complete content
back to the client. The behavior we are seeing on a request is:
- client makes a request to servlet
- server processes request
- client receives approx the first 1/2 of the page as the response
- when you hit 'refresh' in the browser (IE or Netscape) you immediately
receive the second half of the previous response, along with the HTTP
headers and full content of the second response rendered in the browser.
This behavior is repeatable with both IE and Netscape browsers. However, we
do not see this behavior when using Allaire's JRun 3.0 servlet engine.
More specifically, our situation is this :
- an HTTP request comes into our servlet
- this request is packaged up and passed via CORBA to our application server
- the server processes the request and returns a byte[] via CORBA
- we send the response back to the client in the servlet via the code:
// responsePage is a CORBA container class for the application server's
response
// set servlet's response headers:
// the content length header is the same as the length of the byte array
res.setContentLength(responsePage.body.length);
// iterate through the name value pairs and set them in the servlet
headers
NVPArrayToHeaders(responsePage.head.headers, res);
try
{
// get servlet response's output stream send server response byte
array
ServletOutputStream sos = res.getOutputStream();
sos.write(responsePage.body);
sos.flush();
sos.close();
}
catch (IOException e)
{
myLogger.logHTTPError(ServletError.SERVLET_IO_ERROR,res);
myLogger.logError(ServletError.SERVLET_IO_ERROR,e);
}
We have verified that the headers are correct and well formed(by dumping
them to the console), and that the entire response document is contained in
the byte array coming back from the CORBA method (by dumping it to a file).
Am I misusing the ServletOutputStream? Should I wrap the ServletOutpurStream
object with a BufferedOutputStream?
Any help/insights would be appreciated,

Storing property file

Currently I am storing parameters for connecting to a database (i.e. jdbc url, driver, etc.) inside a .properties file. When the app is started for the first time I want the user to enter values for db parameters and then to write them to the property file. Currently I am reading the properties file off the classpath via getResource(). Is there anyway that I can figure where exactly on the file system where the properties file is located at so I can write to it in the correct location??? I took a look at the Jive open source project and they have the user put the location where the file exists on the file system as an entry in the properties file, I would like a more elegant solution. thanks in advance. = ~~~ Scott __ Do You Yahoo!?

Unfortunately I don't run kernel 2.4.x on any of my boxes, so I won't be able to help. However, my advice is that, because Tomcat is 100% pure Java, and pure Java can't core dump (this is not a function of the JVM), then the problem *has* to be with your JDK. I don't expect finding/fixing bugs in a JDK is a trivial task, so you may be better checking for latest versions (or different vendors). Good luck, sorry there's nothing more I can do. Kevin
Re: Tomcat SSL Equifax
I won't call it "stupid", but you are still doing something wrong. In a little greater detail, here are instructions I wrote for the procedure I use (with Tomcat 3.2.1 and IBM JDK 1.3 currently): In response to a Certificate Signing Request, EquifaxSecure sends a mail message containing two "certificates". The first asserts the key binding requested, and is signed by EquifaxSecure. The second is actually a chain of two certificates: one asserts EquifaxSecure's key and is signed by Thawte, and the other is a self-signed certificate of Thawte's. I first tried `keytool -import` on the web server's certificate. This lead to a complaint about keytool not being able to establish trust in the certificate. I fixed this by: (1) using `keytool` to load, as a "new trusted certificate", the certificate-that's-actually-a-chain into $JAVA_HOME/jre/lib/security/cacerts on the web server machine, and (2) adding the "-trustcacerts" flag to the `keytool -import` of the web server's certificate. After that, `keytool -list` shows a chain of three certificates associated with the "tomcat" alias. Upon restarting Tomcat, I find that Netscape 4.75 and IE 5 on my Win 2K laptop both recognize the web site as secure without pestering the user --- provided there is only one key entry in the keystore used by Tomcat (when there is more than one key entry, Tomcat seems to pick one at random to use as the server's SSL/TLS identity). I hope this helps. Mike

When the app is started for the first time I want the user to enter values for db parameters and then to write them to the property file. Currently I am reading the properties file off the classpath via getResource(). Is there anyway that I can figure where exactly on the file system where the properties file is located at so I can write to it in the correct location??? I took a look at the Jive open source project and they have the user put the location where the file exists on the file system as an entry in the properties file, I would like a more elegant solution. FWIW, resources found via getResource() can be written to, when appropriate. I have an article written by Jason Hunter (author of O'Reilly's Servlets book) from JavaWorld Dec. 1998 that covers the changes from servlet spec 2.0 to 2.1 (I don't have the exact URL, but you should be able to find it from that info), and it talks about this there (page 7, near the bottom, "Writing to an abstract resource"). Take a look at that for details. Note that while it is *possible* the URL returned to you by getResource() will be writeable, this is definitely not guaranteed. For example, if your container runs the webapp directly out of a WAR file, it is highly unlikely that you will be able to do this. There is no elegant portable solution to writeable resources within the servlet API. This was discussed by the expert group during the development of the 2.3 spec, but unfortunately no consensus was reached. Using the absolute pathname of a disk file is probably the closest thing to a portable solution. Craig McClanahan

content-length limited to an int?
Hi, Is anyone else having problems with content-length using an int? If I try to serve any files 4gig, the content-length returned is incorrect (I assume the cutoff is 2 gig since ints are signed in java, but I have only tested 4gig files). I took a quick look at the source code, found a method called getHeaderInt() which surely looks the culprit and is surely doing an Integer.parseInt() to get the value. This looks cut and dry to me, am I missing anything? Thanks. _ Get your FREE download of MSN Explorer at http://explorer.msn.com
Should tomcat-auto do this?
When I run Tomcat, it auto-generates an include file for Apache called "tomcat-auto". It uses a directive called "JkMount" to redirect certain URL's to Tomcat's non-http interface. For example, my "tomcat-examples" webapp yields a couple of entries that look like: JkMount /tomcat-examples/servlet/* ajp12 JkMount /tomcat-examples/*.jsp ajp12 So that anything beginning with "/tomcat-examples/" and ending in ".jsp" or anything beginning with "/tomcat-examples/servlet" will get redirected to Tomcat. Okay fine. However, I can define other servlet mappings in the web.xml file that don't get reflected in tomcat-auto. For example, suppose I made a servlet called MyNewServlet.class and put it into tomcat-examples. Let's also suppose that I mapped that to the path "newserv" in my web.xml. If I do this, I can get to the servlet through Tomcat's HTTP port in one of two ways: /tomcat-examples/servlet/MyNewServlet or /tomcat-example/newserv However, going through *Apache*, I can only use the first one, because tomcat-auto tells Apache to only forward requests to Tomcat if it sees something ending in *.jsp or something with "servlet" in the path. So, my question is: shouldn't tomcat-auto also contain JkMount commands for all servlets that I've mapped to paths in web.xml? - Joe

JNDI LDAP Realm for Tomcat 4.0 Tomcat 3.2x alpha3 available: NEED YOUR FEEDBACK!
Title: JNDI LDAP Realm for Tomcat 4.0 Tomcat 3.2x alpha3 available: NEED YOUR FEEDBACK!
Dear tomcat users and developers,
This is an implementation of JNDI and LDAP realm for Tomcat 3 and 4
I would greatly appreciate you feedback regarding its functionality.
Alex Roytman
download from http://www.peacetech.com/java/files/apache/tomcat/
JndiRealm authenticates and authorizes users against JNDI. It was tested against LDAP JNDI
with Sun's and Netscape's jndi providers
LdapRealm authenticates and authorizes users directly against LDAP using Netscape LDAP JDK.
These two realms are interchangeable you can switch between them without many configuration changes.
According to my tests it performs 10 faster under 20 concurrent threads than JNDI with
Sun's LDAP provider. This is not final result because I need to test and tune-up multithreaded
access and synchronization there might be some misunderstanding on my part.
I also noticed some cases of JNDI loosing connection to the server under heavy multithreaded
load while Netscape's LDAP handled it nicely.
There are four classes in the package :
JndiRealm and LdapRealm are for Tomcat 3.2x
JndiRealmCatalina and LdapRealmCatalina for Tomcat 4.0
className=com.peacetech.webtools.tomcat.JndiRealm JNDI TOMCAT 3.2x
className=com.peacetech.webtools.tomcat.JndiRealmCatalina JNDI TOMCAT 4.0
className=com.peacetech.webtools.tomcat.LdapRealmCatalina LDAP TOMCAT 4.0
className=com.peacetech.webtools.tomcat.LdapRealm LDAP TOMCAT 3.2x
Jndi/LdapRealm uses searchBindDN and searchBindCredentials to connect to a directory.
Then it looks for exactly one user name matching searchFilter in searchBaseContext
scoped by searchScopeAsString (values are base, one, sub according to LDAP URL rules)
If one and only one matching directory object is found it will use this object and
tomcat supplied credentials to authenticate the user.
If successful Realm will fetch user roles using JNDI attributes listed in securityAttributes
(comma separated directory attribute names). If attributesReadByOwner = true Realm will use
authenticated user itself to pool the attributes from directory otherwise it will use searchBindDN
to retrieve the attributes.
If roleMapperClass is specified Realm will use it to map user roles onto application roles
specific for each web context for tomcat 3.2x and specific for each defined Realm for tomcat 4.2.
Provided SimpleRoleMapper implementation will read role map from either roleMapperSourceUrl
(if specified) or for tomcat 3.2x from WEB-INF/role-map.xml file in each web context
if no roleMapperSourceUrl was defined (if WEB-INF/role-map.xml file does not exist in a context
no mapping for this context will occur)
PARAMETERS:
jndiInitialContextFactory = com.sun.jndi.ldap.LdapCtxFactory
(or com.netscape.jndi.ldap.LdapContextFactory)
This attribute for JndiRealm ONLY.
It corresponds to javax.naming.Context.INITIAL_CONTEXT_FACTORY
directoryUrl = ldap://207.176.93.66:389
This attribute for both JndiRealm and LdapRealm.
It corresponds to javax.naming.Context.PROVIDER_URL
jndiSecurityAuthentication = simple
This attribute for JndiRealm ONLY.
It corresponds to javax.naming.Context.SECURITY_AUTHENTICATION
jndiSecurityProtocol = ( vendor default or ssl, or vendor specific)
This attribute for JndiRealm ONLY.
It corresponds to javax.naming.Context.SECURITY_PROTOCOL
searchBindDN = cn=ldap-user,o=pti
This attribute for both JndiRealm and LdapRealm. User name to bind to directory
a to perform user name lookups. It corresponds to javax.naming.Context.SECURITY_PRINCIPAL
searchBindCredentials = mypassword
This attribute for both JndiRealm and LdapRealm. Password for searchBindDN
It corresponds to javax.naming.Context.SECURITY_CREDENTIALS
searchBaseContext = o=pti
Base context for user lookups
ldapVersion = 3
This attribute for LdapRealm ONLY. Defines LDAP version.
searchScopeAsString = base | one | sub
defines search scope base - object scope, one - one level scope, sub - subtree scope.
attributesReadByOwner = true
defines who will read securityAttribures from the directory. If true authenticating user account
will be used to retrieve the roles otherwise the searchBindDN account used for user name lookups will
fetch the attributes. It is useful when either one or the other do not have permission to read the
attributes so you can chose the one which has this permissions
searchFilter = cn={0}
Filter to lookup authorizing user. Support java.text.MessageFormat.
The only parameter is to java.text.MessageFormat pattern authorizing username.
i.e. jndiSearchFilter = cn={0} for user alex will result in lookup for cn=alex
securityAttributes = securityEquals
One or more directory attributes separated with semicolon which contains security roles
attributes can be multivalued. If blank no attempt to retrieve roles from directory will be done
roleMapperClass = com.peacetech.webtools.tomcat.SimpleRoleMapper/
ATTNTION: It requires SAX2/JAX1.1 (Apache Xerces or
Tradeoffs: running servlets + EJB in same VM or different VM?
In a J2EE scenario, is it reasonable to consider both the possibility of running the servlet container and the EJB container in the same VM, and running them in different VMs?

URL rewriting ignored for /whatever context path; broken for / context path

rewriting is working OK. I must be doing something to mess
things up. Thanks in advance for your help.

My com.xxx.MyServlet servlet executes the following 3
lines of code as the last step in processing each request in
"doPost":
1. String encodedNextURL = httpServletResponse.encodeURL(this.nextURL);
2. RequestDispatcher rd =
this.getServletContext().getRequestDispatcher(encodedNextURL);
3. rd.forward(httpServletRequest, httpServletResponse);
When my servlet's context path is "/whatever", then
encodedNextURL is always the same as this.nextURL after line 1
is executed.
Why?
The following happens in HttpServletResponseFacade.java for
this.nextURL=/ShoppingStep.jsp
toAbsolute(/ShoppingStep.jsp) returns
http://localhost:8080/ShoppingStep.jsp
isEncodeable(http://localhost:8080/ShoppingStep.jsp) always
returns false at lines 363-368 because
!file.startsWith(contextPath) is true.

if ((contextPath != null) (contextPath.length() 0)) {
String file = url.getFile();
if ((file == null) || !file.startsWith(contextPath))
return (false);
}
encodedNextURL gets assigned /ShoppingStep.jsp
When my servlet's context path is "/", then
this.nextURL get's rewritten and
encodedNextURL gets assigned
/ShoppingStep.jsp;jsessionid=2nrrjkjci1 but
Forwarding the URL (see line 3 above)
"/ShoppingStep.jsp;jsessionid=2nrrjkjci1"
results in a "The document contains no data" message being
displayed by the browser. It appears the jsessionid is the
problem per StaticInterceptor.java lines 199-212, because
file is not a file or a directory as a result of jessionid

2 delegates processing to WorkFlow.processEvent
3 WorkFlow invokes store method on AbstractPortal.Manager ejb reference

4 control returns to AbstractPortal
5 AbstractPortal.service ( servlet ) invokes Manager.store method [ OK ]
both calls can c class access to org.jboss.ejb.plugins.jrmp.server in

if i take ${CATALINA_HOME}/common/lib/jndi.jar and place it in
www/WEB-INF/lib i receive stacktrace 2 @ point 1
i know the sequence works in tomcat 4.0 beta1
launching catalina with -nonaming has no effect
assumption
org.apache.naming is not used in any calls..
the classloader that loaded AbstractPortal also loaded WorkFlow
the classloader that loaded WorkFlow is used to access
AbstractPortal.Manager
question
what is different about these calls..
1 form 3 from 5 ?? except 1 5 occur from the class with the STATIC
reference and is a servlet.. or something..
could it be a subtle classloader/classpath issue??
i will move the code around and try to reproduce it in a simple context..

Hi I wanted to findout if persistent/keepalive connections are supported by tomcat3.2 /3.3 In my application I am trying to invoke a servlet from a C application through plain sockets In my post header I am specifying Connection : keep-alive parameter, however when I try to reuse the connection and post again using the same socket, I get an error saying the socket has been shutdown. So my question is if Tomcat supports connection keep alive and if there is anyother way to support persistent connections in the above scenario. thanks deep _ Get your FREE download of MSN Explorer at http://explorer.msn.com
