Internationalisation problems in Tomcat 3.3?
Hi.
I've seen a couple of posts about problems with i18n and Tomcat. I am having
trouble with this, and at this point I'm suspecting a bug somewhere.
The same test servlet works fine with Apache JServ 1.0, but displays
??? in Tomcat 3.3m4.
Consider the test servlet below. If you call http://yourserver/servlet/test
you get just English. if You call http://yourserver/servlet/test?lang=ja
it should display some Japanese (encoded as euc-jp).
The Japanese text uses the unicode escapes for the appropriate characters.
As I was writing this e-mail, I hit refresh on my site and the Japanese
version worked. I loaded up some English pages, and the Japanese version
went back to ??.
If you uncomment out the resp.getCharacterEncoding() lines you should find
that you get the correct answer for each case.
Any thoughts?
- Ben Kelley.

RE: java.lang.SecurityException: sealing violation?
I had the same problem...with the nightly build. The milestone build was fine, however. No changes in code.

RE: Ordering of parameters in HTTPRequest Object
Hello all, I am new to this mailing list, and Tomcat, so please pe patient... I am using Servlets to recieve html form submissions. Problem is that the form fields are in a particular order on the form, but when I get the Parameters from the request object this field order is gone... The post data comes in in the proper order, but I can not recover the ordering. If it was only 1 form I was dealing with, I could write code to format a response, but the app is very generalized, and it is designed to handle many different forms. So the question. Is there no way in tomcat to preserve the ordering of parameters from a form submission? No. This is servlet API thing, not a tomcat thing. I think it's a bad idea to develop servlet to depend on the order in which a request object is formed because you never know for sure that an ordering is going to be fixed. For example, say a hashing algorithm is used for speed up access. How do you order the elements of a hash table? The only thing I could suggest is preface every form element with its' order, 1st element would be 0_elementname and 9th element would be 8_elementname, then order the elements yourself, but I think this is kind of sloppy. --- Michael Wentzel Software Developer Software As We Think - http://www.aswethink.com

Tomcat JSPs with custom tags SLOW
I develop using Oracle's Web-to-Go servlet container (comes with JDeveloper 3.2.3 IDE). My production environment is Tomcat 3.2. The production environment always seemed just as quick or quicker than my development environment concerning JSPs, until now. I recently started to replace the use of scriptlets with custom tags in my JSPs. Web-to-Go is much faster than Tomcat for the JSPs containing custom tags. My app still has many JSPs that do not contain custom tags and Tomcat is still as fast or faster than Web-to-Go for those scriptlet pages. Are there any performance coding/tuning tips for custom tag development and usage with Tomcat? Does Tomcat 4.0 have better performance with custom tags? -Jerome

My app still has many JSPs that do not contain custom tags and Tomcat is still as fast or faster than Web-to-Go for those scriptlet pages. I would suggest putting some timing tracking code into your tag code as well as the jsp's themselves to try to figure out where exactly the time is being consumed. In addition, you could try messing around with one of the existing tomcat tag libs and see if they give you the same problem. --- Michael Wentzel Software Developer Software As We Think - http://www.aswethink.com

If it was only 1 form I was dealing with, I could write code to format a response, but the app is very generalized, and it is designed to handle many different forms. So the question. Is there no way in tomcat to preserve the ordering of parameters from a form submission? No. This is servlet API thing, not a tomcat thing. I think it's a bad idea to develop servlet to depend on the order in which a request object is formed because you never know for sure that an ordering is going to be fixed. For example, say a hashing algorithm is used for speed up access. How do you order the elements of a hash table? The only thing I could suggest is preface every form element with its' order, 1st element would be 0_elementname and 9th element would be 8_elementname, then order the elements yourself, but I think this is kind of sloppy. Maybe provide another hidden field in your form specifing order (field type=hidden name=field-order value=f1,f2,f3 or something), then add a filter (assuming you use T4.0/S2.3) prividing custom Request adding methods for getting other fields by numbers. --- Michael Wentzel Software Developer Software As We Think - http://www.aswethink.com Greetings, deacon Marcus
RE: Report generation
I have a report which is written as jsp file, and processed at runtime. The jsp generates a report about objects in memory, using their attributes (The object is a JavaBean). The problem now is that I want to save the reports for future use, even when the object has been removed from the memory. Is there any way to save the output of jsp processing to a file? I can think of several ways to approach this. You could create serialized strings for the object and create a repository for these. This would reduce the size of the repository over reproducing the entire report in the repository but it means that whenever the report is requested again it would have to be regenerated. You could also have all your output go to a StringBuffer then .toString() the StringBuffer at the end of the jsp as well as outputting to some sort of repository. Either of these techniques could be encapsulated into a bean or tag. Just a couple of ideas. --- Michael Wentzel Software Developer Software As We Think - http://www.aswethink.com
JasperException / classpath(?) problem
I wonder if anyone can shed any light on the following - I have looked through the archived messages, but to no avail. I have tomcat 3.2.2 installed on Windows 2000 SP2 with jdk1.3.1. I do not have a CLASSPATH environment variable set. When I start tomcat it first says Using CLASSPATH: C:\tomcat\classes;C:\tomcat\lib\ant.jar;C:\tomcat\lib\jasper.jar;C:\tomcat\l ib\jaxp.jar; C:\tomcat\lib\parser.jar;C:\tomcat\lib\servlet.jar;C:\tomcat\lib\webserver.j ar;C:\jdk1.3.1\lib\tools.jar ...which seems fine to me (all the above mentioned jars exist). When I try to run the jsp examples that come with tomcat (e.g. number guess) I get the following exception... org.apache.jasper.JasperException: Unable to compile class for JSPC:\tomcat\work\localhost_8080%2Fexamples\jsp\num\_0002fjsp_0002fnum_0002f numguess_jsp.java:3: Class num.NumberGuessBean not found in import. import num.NumberGuessBean; Is there sthg else I need to add to my classpath in order that tomcat can locate num.NumberGuessBean?

FW: Connector Pools and Downloads?
-Original Message- From: GOMEZ Henri [mailto:[EMAIL PROTECTED]] Sent: Monday, July 16, 2001 5:08 AM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: RE: Connector Pools and Downloads? Michael Rimov [[EMAIL PROTECTED]] wrote : A while back I created a download manager so that I can provide customized security, logging and management. The download manager actually sends the file through the servlet response after setting the appropriate content types and length. So far so good. The Problem This is causing a serious problem under heavy loads. In the case of Resin, the Apache -- Resin connectors came from a fixed block of connections from a pool. Since a multi-megabyte download can take a long time, the connection pool can get filled up rather quickly, and all subsequent servlet responses just crash, or hang for minutes at a time per request. What do you call heavy load ? You can setup Tomcat to handle up to 100 ajp13 threads (and even more) each one handling one download situation. In that case you'll have 100 Apache forked childs forwarding download from servlet engine to client (browser). What to do? Since uploads and downloads seem to be a pretty common entity that people desire for the servlet containers to do, I'm kind of at a loss on how to go about this. AFAICT, the tomcat--Apache connector is going to have the same problems. [If I'm misreading this, I'd LOVE to be corrected! :-) (Also if it isn't a problem is this true for both ajp12 and ajp13? (and ajp14 to be)? )] You'll get the problem before that, at one time you Web-server (Apache or any other one) will have no more process available to handle the download. Imagine you setup Apache Web-server to have up to 250 childs (forked or threaded) 25*10. You set Tomcat to have also 250 ajp13/ajp14 threads available. The 251th client will be rejected by Apache Web-Server before even trying to speak with Tomcat server :! I suppose I can reference count the download manager and only allow so many downloads, but then people are going to go elsewhere instead of wait for a download to be available. Don't forget that mod_jk support load-balancing and you could use 2 or more Tomcat using ajp13/ajp14 behind your Apache Web-Server

RE: When to start a new JVM?
I mean, when do you know that current jvm is fully used and that you should start a new one and balance the load on two? Interesting question. Generally, I'd suggest that you do a load test. You increase the load against the Tomcat instance until the CPU that Tomcat is using isn't increasing any more but the client service time is. This suggests that you've reached the scalability limit of a single Tomcat address space. Then, graph your results. You'll often find a sharp angle in the graph where response time increases sharply with load. Back off from this point a little (say 10%) and that's your maximum throughput for the single JVM, Also, how do you know that current machine has enough load and can't support any more requests, and load should be balanced on two machines? This is easier to do. Assuming you are using Unix, use tools like top(1m), mpstat(1m) on Solaris and ps(1) to check CPU usage. Check memory usage (and paging activity) with vmstat(1m). For NT, PerfMon provides the same sort of facilities via a GUI. For Solaris you can also use the SEToolkit freeware package - it comes with a tool called Zoom that provides instant feedback on whether important areas of the machine are overloaded or not.

RE: Ordering of parameters in HTTPRequest Object
I agree with Michael, it's not a great idea to depend on the order of the request parameters. It makes the code more fragile and less resilient to maintenance. For example, you might want to change the layout of the form to improve usability or change the aesthetics, which would change the order in which the controls appear, and hence the order in which the fields are submitted, which breaks your servlet. Far better to name the parameters. If naming is not possible, you might want to look into reading the request body directly using the ServletRequest.getReader() or ServletRequest.getInputStream() methods. You would then need to parse the data to extract the parameters. I would imagine that you could find similar code in the Tomcat sources, but it's still going to be some work.

how to reloads classes with out restart
hi tomcat users, I´m thinking if anyone has a servlet or something in that way that reloads classes with out restarting tomcat. I´m using a servlet chaining mechanism that I wrote my self. the basic functionality is it has a starter servlet (that always gets reloaded) that reads an xml document that has the rest of the servlets in the chain specified and the parameters for those, and some different functionality in there. So the first servlet in the chain gets reloaded (probably because it get´s the request) but all the other servlets dont unless I restart the server. The Javabeans dont either get reloaded unless I restart the server. So now I´m thinking if there is a functionality within Tomcat that triggers reload on all of the classes available with out restart. Such a functionality is important in a developement face of a web (it´s timeconsuming to have to restart). I can probably write some class or a servlet that reloads by instanciating a new classloader..etc., but someone must have solved this already (right ?) how do you do it ? thanx, -r

The only thing I could suggest is preface every form element with its' order, 1st element would be 0_elementname and 9th element would be 8_elementname, then order the elements yourself, but I think this is kind of sloppy. --- Michael Wentzel Software Developer Software As We Think - http://www.aswethink.com _ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.
Security
I'm starting to look at how to manage security and am wondering what people's experiences are with various security managers. For example, NT-security, Win2k Active directory/LDAP, IBM/Tivoli SecureWay, RYO, etc. In my environment there may be multiple applications on a single server/host. What are the pros and cons of the various approaches (e.g., single vs. multiple realms)? Thanks, Frank Lawlor Athens Group, Inc.

Need help with tomcat.policy and javamail
Hi,
I have a java servlet sending a email via smtp using JavaMail. The servlet
sends out the email fine when executed through telnet session. When I run
the servlet thru Tomcat, I get a java.security.AccessControlException:
access denied (java.net.SocketPermission stage.icarian.com resolve) error.
I'm running this on a cobalt server.
I'm assuming it's a security manager problem. I may be wrong. I need to know
how to configure the tomcat.policy.custom file to fix this problem.
The servlet code:
import java.util.*;
import java.io.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;
public class Mailer {
private String host = stage.icarian.com;
private String to;
private String from;
private String subject;
public Mailer(String to, String from, String subject) {
this.to = to;
this.from = from;
this.subject = subject;
}
public void send() {
Properties props = new Properties();
props.setProperty(mail.smtp.host,host);
Session s = Session.getInstance(props,null);
try {
MimeMessage msg = new MimeMessage(s);
msg.setFrom(new InternetAddress(from));
msg.addRecipient(msg.RecipientType.TO, new InternetAddress(to));
msg.setSubject(subject);
msg.setText();
Transport transport = s.getTransport(smtp);
transport.connect();
transport.send(msg);
// Transport.send(msg);
} catch (MessagingException mex) {
mex.printStackTrace();
}

This assumes that xyz is a resource in your context root Is it possible to translate a relative path to its absolute one in the web pages under Tomcat 4.0b5? hmm but I talking about static resources, calling from a web page not from a servlet, perhaps with a filter that translates the code before sending to the browser client ??

Re: ajp13 dies unexpectately
How many threads have you specified as max_threads in your PoolTCPConnector for ajp13 in your server.xml file? If you haven't done this, and you're running a reasonably high load, you should take a look at the minimal TC user's guide here: http://jakarta.apache.org/tomcat/tomcat-3.2-doc/uguide/tomcat_ug.html The last example at the bottom of the page shows how to configure max_threads, max_spare_threads, and min_spare_threads for the PoolTCPConnector class. Tomcat doesn't react gracefully if the max_threads number is ever reached and exceeded. I believe the default max is 50 threads. If you're getting more than 50 concurrent connections, you need to raise this number or you'll have problems.

Re: Tomcat + Apache on NT
1) Tomcat won't start as a service if the configuration is invalid. However, you don't need to worry too much about the start order if the configuration doesn't change between restarts. 2) You don't need to include it if you have a custom config that includes the relevant information.

The problem relates to the fact that normalization of the request URI (i.e. removing // and /./, and compacting /../) is not being performed consistently. This is going to be fixed (in all versions) such that the request URI received by the server will be normalized *before* being used to map to a servlet, or to select a security constraint. As a side effect, the value returned when you call request.getRequestURI() will always be normalized. Look for announcements of the availability of patched versions shortly. Craig McClanahan

Applet-Servlet communication using Tomcat-Apache cooperation
Hi everybody!! I'm new using Tomcat, instead I'm new developing web applications, so I need help and patient... I'm trying to make a applet-servlet communication thru Apache-Tomcat cooperation. Before I tried it with a Blazix web server, but it was just for tests, because the web server was installed locally in a PC.. and it works perfect and I got the Applet-Servlet communication. Now, I'm trying to do the same with Apache-Tomcat installed in a Solaris Server, and I had been trying that communication for days and I can't yet. I'm trying to make an application that can solve a educational situation, like registration of subjects in my database (Oracle). In this case the Applet only is used like an interface for the user. The user can register a new subject thru the Applet, then the Applet send an object to the Servlet thru a serializable class (Ubc.class) [all this using ObjectInputStream and ObjectOutputStream classes]. The Servlet recieve the Ubc object and interpret it from register all data like a field in a table of the database. Anyway, if the user only want to see all the list of subjects, the Applet sends the url of the Servlet next to a parameter (UserOption = Display) and the servlet recieve the parameter and make a vector with Ubc objects filling them with the database information and finally the Servlet sends the vector with a writeObject method to the Applet, whose displays the information in the screen. And that's all!!. So, in Tomcat I create the next stucture: tomcat-directory/webapps/proyectoprueba2/WEB-INF/classes/ ---in classes directory store the servlet classes and the ubc.class in Apache I did this: apache-directory/htdocs/proyectoprueba2/ ---in proyectoprueba2 directory store the html file that invokes the applet class, of course, I store the applet class, and the ubc.class. Now I invoke the html file and it works very well, but when I tried to register a subject invoking the servlet thru the applet, I only got an error: Error: 500 Location: /proyectoprueba2/servlet/Servlet3 Internal Servlet Error: java.lang.NullPointerException at java.lang.ClassLoader.resolveClass0(Native Method) at java.lang.ClassLoader.resolveClass0(Compiled Code) at java.lang.ClassLoader.resolveClass(Compiled Code) at org.apache.tomcat.loader.AdaptiveClassLoader.loadClass(Compiled Code) at org.apache.tomcat.loader.AdaptiveServletLoader.loadClass(AdaptiveServletLoader.java:174) at org.apache.tomcat.core.ServletWrapper.loadServlet(Compiled Code) at org.apache.tomcat.core.ServletWrapper.init(Compiled Code) at org.apache.tomcat.core.Handler.service(Handler.java:254) at org.apache.tomcat.core.ServletWrapper.service(ServletWrapper.java:372) at org.apache.tomcat.core.ContextManager.internalService(ContextManager.java:797) at org.apache.tomcat.core.ContextManager.service(ContextManager.java:743) at org.apache.tomcat.service.http.HttpConnectionHandler.processConnection(HttpConnectionHandler.java:213) at org.apache.tomcat.service.TcpWorkerThread.runIt(Compiled Code) at org.apache.tomcat.util.ThreadPool$ControlRunnable.run(Compiled Code) at java.lang.Thread.run(Compiled Code) All the classes I did are part of a proyectoprueba2 package, so I had to create the directory... Where do I have put the Ubc class in Tomcat?? I'm working with Tomcat in a stand alone mode. Do I need to connect it with Apache?? HOW??? I had been testing other servlets that are like HelloWorld... they only print a text.. and they works perfect with Tomcat... Can you help me??? I'll be waiting for your help Thank you advanced..

RE: How to change the IP address
I think he means how you set the IP address the server should listen to on a multi-homed host. if this is the case I'm not sure you can do it in Tomcat 3.2.1 if it is possible it would look something like this Connector className=org.apache.tomcat.service.PoolTcpConnector Parameter name=handler value=org.apache.tomcat.service.http.HttpConnectionHandler/ Parameter name=port value=8080/ Parameter name=address value=209.233.3.2/ /Connector Filip ~ Namaste - I bow to the divine in you ~ Filip Hanik Software Architect [EMAIL PROTECTED] www.filip.net -Original Message- From: Dmitri Colebatch [mailto:[EMAIL PROTECTED]] Sent: Monday, July 16, 2001 4:57 PM To: [EMAIL PROTECTED] Subject: Re: How to change the IP address What do you m ean by change the IP address.

jsp changes not reflected/ work dir ?
Hello, OK, so I have a jsp page that has several jsp includes. I was having a problem with the changes being made in one of the includes being reflected in what I saw when I viewed the page through a browser. I tried touching all the files and restarting the server. I then deleted all of the temp files from the work directory. Since then I have restarted the machine altoghter, but there are no updates being reflected. In fact I removed the jsp include that contained the error. Again touched all the *.jsps. Then restarted the server and nothing happened. I think I might have really hosed things. Anyone have an idea on how to get tomcat to recognize the updates I've made?

You should be able to determine IP info on a windows box using winipcfg - I think that's right for NT, can never remember. Whatever IP address the box listens on tomcat will respond to.

Not finding static files (Tomcat 3.2.2. on RH7)
My servlet cannot seem to find static text files, no matter where I put them. This feels like a pretty trivial problem - and I feel pretty dumb asking - but that's my only option, after ten hours of fruitless experiments, alternating with archive-searches of this list, comp.java.lang.*, Sun's Developer Connection, and so on. I'm new to servlets but not to Java. Following examples from Jason Hunter's Java Servlet Programming (O'Reilly, 2d ed.), I had a server file structure like this: [Tomcat root] |webapps |ROOT |WEB-INF |web.xml |classes [assorted 'whatever.class' files] (Purists note: throughout this post, i will write [Tomcat root] as a short-cut for the actual path/usr/local/jakarta-tomcat-3.2.2 .) If I understand Hunter correctly, /ROOT is the virtual equivalent of a file-system root - so if my servlet code refers to a file as /images/mypix.gif, Tomcat will expect to find that file on my system at [Tomcat root]/webapps/ROOT/images/mypix.gif - is that correct? Accordingly, I added two more directories off ROOT: ROOT |html --- contains text file fragment.txt |images |WEB-INF-- contains web.xml But, the following code (which is supposed to read a fragment of HTML boilerplate from a file) consistently throws a FileNotFoundException: System.setProperty(user.dir,[tomcat home]/webapps/ROOT); System.setProperty(user.home,/); String wantedFile = html/fragment.txt); FileInputStream fis = new FileInputStream(wantedFile); Even when a copy of tfragment.txt is placed directly in ROOT, and the namestring wantedFile is changed to just fragment.txt, the FileInputStr constructor still throws a FileNotFoundException. The story gets more baffling. To try to understand what was happening, I inserted these lines between the last 2 above: ServletConfig sConfig = getServletConfig(); ServletContext ctext = sConfig.getServletContext(); String realPath = ctext.getRealPath(wanted); out.println(Attempting to open ' + wanted ' as + realPath); [where, of course, out is a previously-obtained PrintWriter object.) That diagnostic causes the browser to display the text Attempting to open 'fragment.txt' as [tomcat root]/ROOT/html/fragment.txt which is then folowed by the FileNotFoundException report that html/fragment.txt wasn't found - even though it's there!!! Am I misunderstanding the mening of getRealPath() ?? If not, why isn't the file - which really-truly *is* there - being Found? Humble thanks in advance for any and all enlightenment Irv Thomae

web.xml upgrading 3.1 - 3.2.2
I am trying to upgrade my 3.1 install to 3.2 and I am using the web.xml file in the conf directory for some special mappings so Tomcat works in my development enviorment. After installing the new version, it does not seem that Tomcat picks up my servlet mappings. The classes are part of the system class path so I should not have a visibility problem except for maybe a permissions problem and is does not seem like Tomcat is even recognizing the URL. Can anyone help with the problem, below is my web.xml changes. Thanks John G servlet servlet-name cmd-mgr /servlet-name servlet-class com.smart911.gca.CmdMgr /servlet-class /servlet servlet-mapping servlet-name cmd-mgr /servlet-name url-pattern /cmd/* /url-pattern /servlet-mapping
Re: Internationalisation problems in Tomcat 3.3?
Hi!
I had the same problems using a database. I don't know if this applies to
your case, but nevertheless:
I created a database in Cp1250 or Latin2 encoding. Then I have put %@page
contentType = text/html; charset=windows-1250 % on top of my JSP page
and things work now.
Best regards,
Kovi
P.S.: I have done this with MySQL, DB2 and Interbase.

Hi.
I've seen a couple of posts about problems with i18n and Tomcat. I am having
trouble with this, and at this point I'm suspecting a bug somewhere.
The same test servlet works fine with Apache JServ 1.0, but displays
??? in Tomcat 3.3m4.
Consider the test servlet below. If you call http://yourserver/servlet/test
you get just English. if You call http://yourserver/servlet/test?lang=ja
it should display some Japanese (encoded as euc-jp).
The Japanese text uses the unicode escapes for the appropriate characters.
As I was writing this e-mail, I hit refresh on my site and the Japanese
version worked. I loaded up some English pages, and the Japanese version
went back to ??.
If you uncomment out the resp.getCharacterEncoding() lines you should find
that you get the correct answer for each case.
Any thoughts?
