Re: PLEASE HELP ME: JNDI ERROR 1
Put a break point in between and examine Context and its contents. Also
check the spelling/case of datasource lookup name. If you are creating the
Datasource yourself, check for any exceptions during its registration. If
the DS is on an application server, talk to your Server admin.

Subject: PLEASE HELP ME: JNDI ERROR 1
Other information because I don't know what to do.
The exception is created when I call my function getConnection(). The code
is
when I execute con = ds.getConnection();.
The code is:
static {
try {
Context initCtx = new InitialContext();
System.out.println([DEBUG] Dopo l'InitialContext = +
initCtx.toString());
Context envCtx = (Context) initCtx.lookup(java:comp/env);
System.out.println([DEBUG] Dopo lookup java:comp/env = +
envCtx.toString());
DataSource ds = (DataSource) envCtx.lookup(dbName);
System.out.println([DEBUG] Datasource = + ds.toString());
con = ds.getConnection();
if (con == null)
System.out.println([ERROR] Connessione nulla);
} catch (Exception ex) {
System.out.println([ERROR] Errore = + ex.toString() + \n +
ex.getMessage());
con = null;
}
}
protected synchronized Connection getConnection() {
while (conFree == false) {
try {
wait();
} catch (InterruptedException e) {
System.out.println([ERROR] Eccezione nella getConnection()

}
}
conFree = false;
System.out.println([DEBUG] Punto 1);
notify();
System.out.println([DEBUG] Punto 2);
return con;
}
Please help me.
Before this code was ok. Has someone some idea?
Help.

Re: AW: PLEASE HELP ME: JNDI ERROR 1
Thats a very good point. Also, look for any other old set of classes which Tomcat is picking up. Which may mean JNDI related classes too. I dont know if this would work but, change the time stamp's of all tomcat related .xml files by making a small change like adding a space, pressing enter etc and see if it makes any difference. regards hemant - Original Message - From: Angel Municio [EMAIL PROTECTED] To: 'Tomcat Users List' [EMAIL PROTECTED] Sent: Monday, April 15, 2002 1:00 PM Subject: RE: AW: PLEASE HELP ME: JNDI ERROR 1 If the Oracle database that you are trying to connect to is a different version than the old one, check for updated Oracle jdbc drivers (classes12.zip).

Re: someone....need help!!!!....
Hi 2 Options: 1Search for the Work Folder under tomcat. Check for a folder that has the same name as Tomcat. Delete the .java and JSP file of the page you want to test. 2Open the JSp you want to test, hit enter somewhere in between the lines. This way you can force a re-compile on the JSP. possible silly mistake Make sure that you are changing the right JSP in the right directory.(Especially when you maintain copies, silly mistakes do happen.) later hemant - Original Message - From: ajith kondapalli [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Tuesday, April 09, 2002 11:28 AM Subject: someoneneed help hai, I have just started using tomcat to deploy some webapps...the problem:I create the webapps for the first time and deploy them,it saves the changes and runs properly..but later changes in the JSP i am makin are not reflected in the outputso if i run the program for the first time then it shows the changes but later after i make some changes and run it the second time,it doesnt reflect those changesi dont undertsand what the problem issomeone plz help...!!! thanks ajith __ Do You Yahoo!?

Re: java.lang.ClassFormatError out of the Blue
Jason Thanks for the response. The absence of scripts in binary mode clearly justifies the exception. Iam trying to run it in my own Test Environment. And moreover, the .class files are in the repository. Even if I export them, they seem to get exported in corrupted format. Iam trying to export .Java files, delete project from workspace/repository, and import all the java files again. Hoping that would work.

Re: someone....need help!!!!....
Ok I think its different from jsp inclusion case but let me clarify Here is your case dbquery.jsp -submit on dbquery.jsp addproc.jsp Here is what Sean suggested ((jsp1) jsp2) (here there is no question of one invoking the other.) If JSP1 changes, JSP2 also has to change because jsp2 includes jsp1 . If the above description is correct, then we are talking 2 different scenarios. In the first scenario changes in 2 JSP's can be viewed independent of each other. If you make changes to addproc.jsp and still dont see it, then check the JSP. I wonder if you have some kind of scriptlet/logic tag that has to evaluate to something for your changes to kick off? or could it be that your changes are throwing an exception, you are catching them in the scriptlet and doing nothing with it? If you have an IDE such as Visual Age, switch the JSP debugger on and debug the part where u expect a change.

help with diretories in servlets
Hi ! I am trying to create a samll web application which will query the database depending upon the input parameters provided, generates XML file from the Result Set, applies XSLT and generates HTML, which in turn I want to display in a frame. I want to organize those files in following way relative to my web application path. Reports ( my root path ) | | - forms ( which will contain forms to accept input parameters ) | - xml ( which will store converted XML file from the Result Set ) | - xslt ( which will contain pre generated XSLT files ) | - html ( which will store transformed HTML file ) I am initializingfollowing variables _xsltFileName = request.getContextPath() + \\xslt\\newCommodities.xslt ; _xmlFileName = request.getContextPath() + \\xml\\newCommodities.xml ; _htmlFileName = request.getContextPath() + \\html\\newCommodities.html ; and using following code to transform and display HTML. transformXML( _xmlFileName, _xsltFileName, _htmlFileName ) ; response.sendRedirect( _htmlFileName ) ; What is wrong with this, as I am not able to create HTML file in /html/ directory, and obviously not able to display the file as it doesn't exist there.

Re: Automaticaly update the servlets
HI Randy and Milt: I strongly believe that issue is not at all related to classpath, As offcourse servlets are loaded by tomcat server, and in case they uses suns classloader i guess it not at all caches the loaded class, Is there any sun guy which can clarify this? Regards, Hemant - Original Message - From: Randy Layman [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Friday, June 08, 2001 7:55 PM Subject: RE: Automaticaly update the servlets The problem is that the System class loader (the one that loads your CLASSPATH environment variable) is keeping a cache around of the class. This is why Milt (correctly) told you to remove the WEB-INF/classes from your classpath if you want the auto-reloading to work as it is supposed to*. If the System class loader loads your class then its impossible for Tomcat to load it, and if Tomcat doesn't load it in the first place, then it can't unload and reload it. Randy * - Many people have problems with the way that auto-reloading works in Tomcat. A large number have problems like yours, and large numbers also complain that the auto-reloading doesn't work for non-servlet classes (which it doesn't due to complexity of the problem). -Original Message- From: Pablo Morillas [mailto:[EMAIL PROTECTED]] Sent: Friday, June 08, 2001 10:29 AM To: [EMAIL PROTECTED] Subject: Re: Automaticaly update the servlets Yes, it is in my classpath.

Tomcat is running a servlet that performs XSLT transformations on an XML file that is ~1.4MB big and returns html output to the client browser. It was running fine during development, but once the servlet was made available to the web site's users (www.coolrunning.com), it began crashing. Must be due to the increased load. I don't know how heavy the load is exactly, nor how to determine it, but the site is not an Ebay by any means. I'm assuming Tomcat can handle a single servlet application on a low-traffic web site -- less than 100,000 hits a day. Following suggestions on the web, I've - Increased the memory allocated to Tomcat to 128M (using -Xmx128m switch) - Increased the max_threads to 100 - Increased the file descriptors to 256 - added System.gc(); to the end of the Servlet code These changes have helped; it takes much longer, but it still crashes under normal use. I've been watching the output from the top command. It shows that the Tomcat Java process is starting with about 32MB and over time and load it climbs. It was running at 62M for quite a while, and it even dropped to 55M, and then grew to 169M without crashing. Not sure how high the SIZE (memory) gets to before it crashes; but crash it does with a core dump. With the 'ps' command, I don't see any accumulation of treads. Here's a dump 81= /usr/ucb/ps -auxww | grep thread root 24231 73.0 28.3173016141648 ?R 20:30:02 21:51 /usr/local/j2sdk/ bin/../bin/sparc/native_threads/java -Xmx128m -Dtomcat.home=/usr/local/tomca t or g.apache.tomcat.startup.Tomcat I don't know how to analyze the core dump, except to use strings on it. At least, I can see that it was definitely caused by Tomcat. What would be a reasonable setting on max_threads? Is 100 just to low? I could start Tomcat with more memory, say 256M (system has 512MB), but I don't want to negatively impact the other applications. The system is running Apache without any problems, independent of Tomcat. I've spent months developing this JSP/Servlet application for the Coolrunning Events calendar, and can't go back. Have to make Tomcat work! Any help appreciated. Tom
Re: get/setAttribute and getParameter...
HI Zinger:
answer to this question depends on env conditions
setAttribute method stores the attribute in JVM itself for every session,
while set parameter will pass the attribute as a header information to you
new jsp.
So it all depends on memory available, cpu speed, and no of pages you are
going to use this technique.
Cheers

Subject: get/setAttribute and getParameter...
Hi,
What is more time consuming?
JSP1:
% request.setAttribute(FLAG, new Boolean(true)); %
jsp:include page=JSP2.jsp flush=true/
JSP2:
% boolean FLAG = ((Boolean)
request.getAttribute(FLAG)).booleanValue();
if (FLAG) {
..
...
}
%
OR?:
JSP1:
jsp:include page=JSP2.jsp?FLAG=true flush=true/
JSP2:
% String FLAG = request.getParameter(FLAG);
if (FLAG.equals('true)) {
..
..
}
%
OR?:
JSP1:
jsp:include page=JSP2.jsp?FLAG=true flush=true/
JSP2:
% boolean FLAG = (new
Boolean(request.getParameter(FLAG))).booleanValue();
if (FLAG) {
..
..
}
%
AND, which way is it best practiced.
Thankss for any help!

Re: Using Realm
Sorry to be little bit unspecific in my question, I was talking abt MemoryRealm, but i don't want to load it from conf/tomcat-users.xml but from some different flat or xml file. Is that possible ? Hemant - Original Message - From: Pernica, Jan [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, May 31, 2001 4:40 PM Subject: RE: Using Realm Which one? You can use MemoryRealm, which loads user info from conf/tomcat-users.xml or you can use JDBCRealm, which loads user info from database After that you have to define your security constratins in the web.xml Regards Jan On Thursday, May 31, 2001 1:10 PM, Hemant Singh [SMTP:[EMAIL PROTECTED]] wrote: HI ALL: Can any one tell me how to use Realm with tomcat.

Session Cookie relation
HI ALL: I found a strange problem which i later solved after a lot of debugging, If my servlet is setting a cookie than after closing and reopening and giving new hit from browser give me two different session values, that is if i access session without reading cookie than i get different session value than i get when i access session after reading cookie. Is it some feature which i was unaware of that? Thanks all, Hemant Singh
