suggestions for avoiding javascript problems
some problems that I faced using javascript libraries - sometimes the libraries will not be loaded, especially in very slow connections. Because of this, the other scripts in the page might not execute. This is a big problem especially if you have some dynamic menus etc. The only solution is to add all the script into the page itself using include commands. - if you do something in the onLoad() javascript function, it might not get executed. This is because the onload function fires only when all the elements of the page including images, applets etc are loaded. - put the javascript for image rollover effects in the top of the page. If you put in the bottom of the page, the page elements would have been rendered on the screen but the javascript will not be available. This would show some javascript errors and would stop all other scripts in the page! -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED]

RE: JPeg Image Encoder problem under Tomcat 3.2
I guess you are pressing the stop button in the browser. The exception is thrown because you are interrupting the communication between the browser and the servlet. This should be thrown even if you are not resubmitting the form. Try to change the code of the servlet so that when this exception occurs it does not affect future requests to the servlet. Check if you can do some caching mechanism, ie storing the entire image in memory if it does not change often and the size is not too big. This will make the servlet faster. -Original Message- From: LeRoux van Wyk [mailto:[EMAIL PROTECTED]] Sent: Friday, October 19, 2001 11:02 AM To: [EMAIL PROTECTED] Subject: Re: JPeg Image Encoder problem under Tomcat 3.2 The same problem occurs in Netscape under Windows,Linux and Mac.

RE: ServletException that I don't understand...
Hi,
The error is in this line
int lineNr = Integer.parseInt(nr);
It means that nr is not containing a valid integer.
to find out the value in nr, you can give something like
System.out.println(value of nr is : +nr);
int lineNr = Integer.parseInt(nr);
likewise you can give System.out statements wherever necessary and
find out where the value is not getting assigned properly.

Server !-- Debug low-level events in XmlMapper startup -- xmlmapper:debug level="0" / !-- Logging: Logging in Tomcat is quite flexible; we can either have a log file per module (example: ContextManager) or we can have one for Servlets and one for Jasper, or we can just have one tomcat.log for both Servlet and Jasper. Right now there are three standard log streams, "tc_log", "servlet_log", and "JASPER_LOG". Path: The file to which to output this log, relative to TOMCAT_HOME. If you omit a "path" value, then stderr or stdout will be used. Verbosity: Threshold for which types of messages are displayed in the log. Levels are inclusive; that is, "WARNING" level displays any log message marked as warning, error, or fatal. Default level is WARNING. verbosityLevel values can be: FATAL ERROR WARNING INFORMATION DEBUG Timestamps: By default, logs print a timestamp in the form "-MM-dd hh:mm:ss" in front of each message. To disable timestamps completely, set 'timestamp="no"'. To use the raw msec-since-epoch, which is more efficient, set 'timestampFormat="msec"'. If you want a custom format, you can use 'timestampFormat="hh:mm:ss"' following the syntax of java.text.SimpleDateFormat (see Javadoc API). For a production environment, we recommend turning timestamps off, or setting the format to "msec". Custom Output: "Custom" means "normal looking". "Non-custom" means "surrounded with funny xml tags". In preparation for possibly disposing of "custom" altogether, now the default is 'custom="yes"' (i.e. no tags) Per-component Debugging: Some components accept a "debug" attribute.

You can also specify a "randomClass" attribute, which determines a subclass of java.util.Random will be used for generating session IDs. By default this is "java.security.SecureRandom". Specifying "java.util.Random" will speed up Tomcat startup, but it will cause sessions to be less secure.

RE: Defining an init parameter for all servlets
hi,
I had the same problem. I overcame it by giving something like
getServletContext("context_name").getInitParameter().Please check the exact
syntax from the servlet api
Now I am using a static class to hold all the initial values in a hashtable.
In the static initializer, I am populating
the hashtable with values from a database.
regards

Subject: Defining an init parameter for all servlets
I would like to define some initialization parameters to be used by
all servlets running on Tomcat.
Is there a way to define this in web.xml, besides copying the init-param
section of the global parameter to every servlet's section in web.xml?
[Kitching Simon] Yep!
To set a parameter accessable by all servlets
*in a web application*, see "context-param" tag
(or is it config-param?) in the sun servlet specification...

There is an utility called jspc. To use the generated servlets, the web.xml file has to be modified to specify the servlet mapping for the jsp file.

RE: precompile jsp
Hi Joan, From what I experimented with jspc I found the following.. you can put the generated class files any where in tomcat's classpath. I put them in webapp\web-inf\classes. The web.xml file of the web app has to be changed to add the servlet and servlet-mapping tags. The server uses these to find the servlet for the .jsp file. If the mapping is wrong or missing, it generates the .java file in the work directory. The web.xml file can be created using the -webxml option. One problem which I had was that the generated web.xml had the wrong slashes, I found that out by comparing the generated xml file with the web.xml in the examples context. when I edited it manually, tomcat did not create the .java files but used the pre-compiled classes. I feel that jspc should do exactly what the server does at run time, i.e., generate the java classes in the same way. Regards, Nagaraj. -Original Message- From: Joan Xiao [mailto:[EMAIL PROTECTED]] Sent: Thursday, December 14, 2000 1:57 AM To: [EMAIL PROTECTED] Subject: precompile jsp Hi all, I've been trying to use jspc to precompile the jsp pages into java classes. Below is the steps I've taken: 1. run jspc and generate the java code and web.xml 2. insert the web.xml generated in step1 into my web.xml. 3. compile the java files into class files. Now I have problem with where to put the class files. Should they be under the web-inf\classes or the work\ directory? I put them under web-inf\classes. And I have the classes preserve the package/directory structure. 4. restart Tomcat. Result: the jsp pages under the first level directory are not re-compiled by Tomcat, but those under the 2nd level directory are re-compiled. For example, suppose I have the following directory structure: webapps + registration + enroll + web-inf + classes The jsps under registration/ are not recompiled, but those under registration/enroll are re-compiled by Tomcat, as I can see the java/class files in the work/ directory. How can I make it work? Do I have to put the classes files under work/ and name them the same way Tomcat names them? Thanks for any help. Joan

RE: Ant compile error
hi, you have to download the ant and xerces packages and put them in the classpath. Using the approach mentioned in the doc is good if you have to manage a project. If just want to try out some examples, you can ignore it.

RE: $20 bucks to the 1st person who actually solves my problem!!! - WE HAVE A WINNER!!!
This is off topic but this reminds me that most of the time we try to solve problems thinking that we have understood the problem completely and have an intuition where the solution is. And we spend lots of effort and time trying to fix the imaginary problem. Like in this case, we thought it was due to caching and tried to fix it and it has turned out to be with the database part ! I wonder what Adress would have done without this mailing list! -Original Message- From: Adress, David S.

valueUnbound() event in HttpSessionBindingListener
Hi everyone, This is regarding tracking of login and logout actions of users. I am recording the session creation time and end time using the HttpSessionBindingListener class. The two methods valueBound() and valueUnbound() are invoked. But the getAtrribute() method in the session object returned by event.getSession() always give null. I am storing the userid and a string in the session to indicate if the user has logged out. By checking this string's value I can find out if the user has logged out or the session has timed out. What I did to solve this problem was to store the sessionid and the userid in an external database. When the user logs out, before invalidating the session, I put "LoggedOut" in the loginStatus column. In the valueUnbound() event, I check the value of the loginStatus column to check if the event has been called because of the user logging out or if the session has timed out. How is it actually done internally? i.e., is there a thread similar to the garbage collector which checks the current sessions or is the session invalidated only when a request comes from the client. The second option will mean that the objects in the session will be occupying memory till the server is shutdown. Has anyone implemented anything similar to this. Thanks, Nagaraj.
