RE: site slow problems
Well, I would guess that it loads quickly when you're not connected if it's cached on your disk. I've had intermittent problems with tomcat running slow before and usually re-deploying does the trick. If that fails I restart tomcat. If that still doesn't work I suggest checking that any connections you open (eg. for SQL Database or for file-writing) are closed. Of course I'm not sure that explains why it worked under RedHat but it's worth I try and RedHat can be a bit strange sometimes...

OracleConnectionPoolDataSource creates too many connections
Hi All,
My web application is using up all connections after running for a while.
It's quite obvious that I'm not using the connection pool as it was designed
to be used. The only way I can get these connections back is by restarting
the Tomcat. I have ojdbc14.jar in the following directories:
$CATALINA_HOME/commons/lib directory
$CATALINA_HOME/webapps/myWebApp/WEB-INF/lib.
This code creates my connection Pool
private void createConnectionPool( ) {
try {
// Create a OracleConnectionPoolDataSource instance.
connectionPoolDS = new OracleConnectionPoolDataSource( );
String url = jdbc:oracle:thin:@194.26.151.17:1521:mosaic;
connectionPoolDS.setURL( url );
// Set the user name.
connectionPoolDS.setUser(mosaicuser);
// Set the password.
connectionPoolDS.setPassword(mosa1c);
}
catch ( SQLException ex ) { // Catch SQL errors.
//context.log( ex.toString( ) ); // log errors.
}
}
This code creates a PooledConnection.
-
public static synchronized PooledConnection getPooledConnection(){
try{
pooledconn = connectionPoolDS.getPooledConnection();
}catch(SQLException sqle){
sqle.printStackTrace();
}
return pooledconn;
}
In my LoginServlet, I create a new PooledConnection, which I add to the
Servlet Context:
PooledConnection pc = ConnectionFactory.getInstance.getPooledConnection();
ServletContext ctx = getServletContext();
ctx.setAttribute(pooled_conn, pc);
On an JSP Page:
ServletContext ctx = getServletContext();
PooledConnection pc = (PooledConnection)ctx.getAttribute(pooled_conn);
Connection con = pc.getConnection
//do a few things with the connection
try{
if (con != null){
con.close();
} // I'm assumingthis returns the connection to the Pool
}catch(SQLException sqle){
sqle.printStackTrace();
}
Any help to solve this mystery would be very much appreciated.
Kind Regards,
Rudi

RE: OracleConnectionPoolDataSource creates too many connections
Hi,
You still need to create a connection cache with that datasource, so
something like :
OracleConnectionPoolDataSource ocpds = new OracleConnectionPoolDataSource();
...
OracleConnectionCache oracleConnectionCache = new
OracleConnectionCacheImpl(ocpds);
You can then call the following to get connections from the pool :
oracleConnectionCache.getConnection();
Be sure to close all your connection when you are done so they are returned
to the pool.
Ryan.

RE: OracleConnectionPoolDataSource creates too many connections
Probably you are not closing all the objects. It depends on pool used and
app server but is a good idea (and more portable) to close all the
objects. Many pools crash if you only close (return) the connections.
after using the rs object (ResultSet) -- rs.close()
after using the st object (Statement) -- st.close()
after using the pst object (PreparedStatement) -- pst.close()
after using ... (all the jdbc objects)
You must close, to avoid errors, in reverse order as they were
instantiated.
Try it, i have no read your code and could be other problems.
Hope this help

Where to store log files from packed WAR file apps
Hello Now that I've got my Ant build/deploy scripts working nicely, I'm tempted to start running my applications out of packed WAR files. I cannot figure out if there is a *portable* way to specify paths for where my Log4J log files should be saved. I assume I could use the 'catalina.home' property to save the logs under the Tomcat installation directory - but that's Tomcat specific. Has anyone got around this, somehow, or is it a case of getting Ant to glue things with some hard-coded values at build time? Many thanks for any contributions.

addShutdownHook in Tomcat does not seem to get called on shutdown
Hi,
I added a shutdown hook in my app, which works fine when I run it in
standalone mode, but which does not seem to get called when Tomcat stops.
The shutdown hook operates according to following the following semantics:
__
class MyApp{
public void doSomething(){
ShutdownHook sdh = new ShutdownHook();
synchronized(Runtime.getRuntime()){
Runtime.getRuntime().addShutdownHook(sdh);
}
//
//do something here
//
logger.info(Finished doing something);
//remove shutdown hook once process has finished
sdh.setFinished();
if (!sdh.isInitialised()){
synchronized(Runtime.getRuntime()){
Runtime.getRuntime().removeShutdownHook(sdh);
}
}
}
private class ShutdownHook extends Thread {
private boolean INITIALISED = false;
private boolean FINISHED = false;
public void run() {
this.INITIALISED = true;
this.setPriority(2);
logger.debug(Shutdown hook: shutdown thread started - a
shutdown has
been requested);
out :
while (true) {
//keep on looping until the claaing app has finished
synchronized(this.FINISHED){
if (this.FINISHED == true) {
logger.debug(Shutdown hook: parent
program finished, allowing
shutdown process to complete);
return;
}
}
}
}
public synchronized boolean isInitialised() {
return this.INITIALISED;
}
public synchronized void setFinished() {
this.FINISHED = true;
}
}
}
__
The log does not show any trace of the shutdown hook being called, and
the process does indeed not complete before Tomcat shuts down, which to
me sounds like the hook is not getting registered properly for some
reason. Any ideas why this might be happening? I am running Tomcat
4.1.18 on Windows 2K (no advice about switching to Linux please).
Thanks,

GlobalNamingResources global how?
Could someone please help and explain to stupid me? I'm developing using ant deploying/undeploying a lot at the moment and I want to have access to my MySql connectionpool that I've registerd as a GlobalNamingResource in server.xml. The problem is that I can't access it (Cannot load JDBC driver class 'null') when the app I'm working on is not registered as a Context in server.xml but rather deplyed with the Manager webb application. I've also registered an exact copy of the resource with the /examples context to verify that the connection parameters and the java code is ok. So that's not the problem. (but accessing the global resource didn't work there ither...) In the web.xml for the app I'm developing I have the resource-ref set up like: resource-ref res-ref-namejdbc/mysql_devdb/res-ref-name res-typejavax.sql.DataSource/res-type res-authContainer/res-auth /resource-ref and the Resource under GlobalNamingResources is named jdbc/mysql_tdb. Question: Is what I'm trying even possible, or do I *have* to put the app I'm developing as a Context in server.xml?

Re: RE: OracleConnectionPoolDataSource creates too many connections
You need to use the .close method for every connection. If your new connection is called conn then it's conn.close(); Check your max connections in server.xml (probably for port 8009) but if you're not closing your connections this will only delay a crash not stop it. I suggest the java.sun.com site for info on Java classes and methods. You could use this link: http://java.sun.com/j2se/1.3/docs/api/ Adam. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: addShutdownHook in Tomcat does not seem to get called on shutdown
mainly because i was trying to write a single class for both the tomcat
and standalone versions, and also to avoid making the business logic
dependent on a web environment. (ie to provide fail-safeness within the
business logic, rather than it being an external service that needs to
be checked)

Subject: RE: OracleConnectionPoolDataSource creates too many connections
Hi,
You still need to create a connection cache with that datasource, so
something like :
OracleConnectionPoolDataSource ocpds = new OracleConnectionPoolDataSource();
...
OracleConnectionCache oracleConnectionCache = new
OracleConnectionCacheImpl(ocpds);
You can then call the following to get connections from the pool :
oracleConnectionCache.getConnection();
Be sure to close all your connection when you are done so they are returned
to the pool.
Ryan.

Subject: OracleConnectionPoolDataSource creates too many connections
Importance: High
Hi All,
My web application is using up all connections after running for a while.
It's quite obvious that I'm not using the connection pool as it was designed
to be used. The only way I can get these connections back is by restarting
the Tomcat. I have ojdbc14.jar in the following directories:
$CATALINA_HOME/commons/lib directory
$CATALINA_HOME/webapps/myWebApp/WEB-INF/lib.
This code creates my connection Pool
private void createConnectionPool( ) {
try {
// Create a OracleConnectionPoolDataSource instance.
connectionPoolDS = new OracleConnectionPoolDataSource( );
String url = jdbc:oracle:thin:@194.26.151.17:1521:mosaic;
connectionPoolDS.setURL( url );
// Set the user name.
connectionPoolDS.setUser(mosaicuser);
// Set the password.
connectionPoolDS.setPassword(mosa1c);
}

Hi, We need to configure SSL on Tomcat4 server. The web service has to authenticate the client using certificate. We followed the document which has been attached along this mail. 1.

If we modify the server.xml manually then also we are getting the same problem. 3. If we comment the non-SSL part in the server.xml after step 2, the page is displaying but the tomcat is not starting properly.

Subject: addShutdownHook in Tomcat does not seem to get called on
shutdown
Hi,
I added a shutdown hook in my app, which works fine when I run it in
standalone mode, but which does not seem to get called when Tomcat
stops.
The shutdown hook operates according to following the following
semantics:
___
___
class MyApp{
public void doSomething(){
ShutdownHook sdh = new ShutdownHook();
synchronized(Runtime.getRuntime()){
Runtime.getRuntime().addShutdownHook(sdh);
}
//
//do something here
//
logger.info(Finished doing something);
//remove shutdown hook once process has finished
sdh.setFinished();
if (!sdh.isInitialised()){
synchronized(Runtime.getRuntime()){
Runtime.getRuntime().removeShutdownHook(sdh);
}
}
}
private class ShutdownHook extends Thread {
private boolean INITIALISED = false;
private boolean FINISHED = false;
public void run() {
this.INITIALISED = true;
this.setPriority(2);
logger.debug(Shutdown hook: shutdown thread
started - a
shutdown has
been requested);
out :
while (true) {
//keep on looping until the claaing app
has
finished
synchronized(this.FINISHED){
if (this.FINISHED == true) {
logger.debug(Shutdown
hook: parent
program finished, allowing
shutdown process to complete);
return;
}
}
}
}
public synchronized boolean isInitialised() {
return this.INITIALISED;
}
public synchronized void setFinished() {
this.FINISHED = true;
}
}
}
___
___
The log does not show any trace of the shutdown hook being called, and
the process does indeed not complete before Tomcat shuts down, which to
me sounds like the hook is not getting registered properly for some
reason. Any ideas why this might be happening? I am running Tomcat
4.1.18 on Windows 2K (no advice about switching to Linux please).
Thanks,
Elie

RE: Where to store log files from packed WAR file apps
Hi, Might be wrong on this but why not setup environment variables and reflect those in ant? That way you should be portable, providing those env vars exist. BTW, take off the tomcat greeting page from your machine ;) That's one possible solution. Another is to setup a build.properties file with tokens, e.g. @logfile@ and have the ant deploy script populate your web.xml (or whatever configuration file you want) with the appropriate value of this token. (See Ant's copy filter token mechanisms). Yet another approach, and probably the most enterprise like, is to specify the log file location via JNDI. Have an env-entry-ref in your web.xml (this is constant, will not changed, so you don't need to change your WAR), and have the server administrator fill in the appropriate value for their server (e.g. in server.xml for tomcat).

Re: RegExp issues with Tomcat 5
Karl,
Using the regexp tag library I think it is still at version 1.0.
Because INSERT into tablename (field1) values ('I CAN'T DO THIS')
generates an error in SQL Server.
If you use a PreparedStatement, then you can send any string to the
statement object and it will do it's own escaping.

Re: Global URL Redirect Tomcat 5
Nathan, I am trying to migrate to Tomcat 5 from a different app server. Is there a way to define url redirects? i.e. if a page moved off your server to a different location and you do not want to make a redirect page. You could write a servlet that's mapped to /*, and then have that servlet replace the hostname (and part of the path?), then send a redirect back to the browser. Would this meet your needs? -chris signature.asc Description: PGP signature signature.asc Description: OpenPGP digital signature
Re: ClassNotDefError problems within JAR files under Tomcat 4.1.12
Nathan, I am developing an imaging servlet under Tomcat 4.1.12 using JAI 1.1.2. Every time I update my code to add new features, it will return with a NoClassDefFoundError until I restart Tomcat. At that point, it finds the 'missing' class and everything works as expected. I'm no expert on JAI, but I believe that it uses JNI and a native library to do some of it's dirty work. If that's the case, then you should make sure that the JAI JAR file and native library are loaded by a classloader outside (higher than) your webapp. There's documentation on the Tomcat site (and probably other servlet containers, too) that says that native libraries should only be loaded one time. IF they get loaded multiple times (as would happen if they were loaded by the webapp), strange behavior can result. Try putting jai.jar (or whatever) into TOMCAT_HOME/common/lib and jai.so (or whatever) in a convenient place where it can be found. (Sorry, dunno where that might be. Anyone else?)

RE: addShutdownHook in Tomcat does not seem to get called on shutdown
A-ha - it seems the shutdown hook does not get called when tomcat is run
as a service, but does seems to get called when run as standalone. In
that case it would seem that the problem would lie with the way the
service is configured (ie what it does to stop) compared to the
standalone version, I haven't had time to look at that yet.
I was removing the shutdown hook because once the sensitive task has
run, it doesn't need to be there anymore - the idea was to allow the app
to exit gracefully if it was doing something sensitive (eg inserting a
bunch of related data into a DB) by looping through the shutdown thread
until the business object was done, rather than shutdown the app in a
way which might affect data integrity. I was trying to avoid a flurry of
unnecessary shutdown hooks staying registered even though the calling
logic had long since completed.
I'm not sure how good an idea it is to use a shutdown hook to do this in
tomcat though - I'm not sure how things work when the context gets
destroyed. From what I understand, in theory all the objects required by
the logic should be keep alive until all references to them disappear
(from the object requesting the shutdown hook for instance). In practice
though, I get a lifecycle error: CL stopped Exception from tomcat on
shutdown and the shutdown hook in my example keeps on running in an
infinite loop. I read somewhere that it had to do with classloader
issues in some version of tomcat 4
(http://nagoya.apache.org/bugzilla/show_bug.cgi?id=3888), but i'm not
sure that applies here. In any case it would seem that the shutdown hook
might not be the best solution here, and that i will probably have to
provide separate standalone and tomcat wrappers to the business logic :(
oh well...
thanks for your help
Elie
Hi,
You're probably removing the shutdown hook too early. Why are you
removing it at all?

Subject: addShutdownHook in Tomcat does not seem to get called on
shutdown
Hi,
I added a shutdown hook in my app, which works fine when I run it in
standalone mode, but which does not seem to get called when Tomcat
stops.
The shutdown hook operates according to following the following
semantics:
___
___
class MyApp{
public void doSomething(){
ShutdownHook sdh = new ShutdownHook();
synchronized(Runtime.getRuntime()){
Runtime.getRuntime().addShutdownHook(sdh);
}
//
//do something here
//
logger.info(Finished doing something);
//remove shutdown hook once process has finished
sdh.setFinished();
if (!sdh.isInitialised()){
synchronized(Runtime.getRuntime()){
Runtime.getRuntime().removeShutdownHook(sdh);
}
}
}
private class ShutdownHook extends Thread {
private boolean INITIALISED = false;
private boolean FINISHED = false;
public void run() {
this.INITIALISED = true;
this.setPriority(2);
logger.debug(Shutdown hook: shutdown thread
started - a
shutdown has
been requested);
out :
while (true) {
//keep on looping until the claaing app
has
finished
synchronized(this.FINISHED){
if (this.FINISHED == true) {
logger.debug(Shutdown
hook: parent
program finished, allowing
shutdown process to complete);
return;
}
}
}
}
public synchronized boolean isInitialised() {
return this.INITIALISED;
}
public synchronized void setFinished() {
this.FINISHED = true;
}
}
}
___
___
The log does not show any trace of the shutdown hook being called, and
the process does indeed not complete before Tomcat shuts down, which to
me sounds like the hook is not getting registered properly for some
reason. Any ideas why this might be happening? I am running Tomcat
4.1.18 on Windows 2K (no advice about switching to Linux please).
Thanks,
Elie

Re: reclaiming memory problem PS
Jerald, session.setMaxInactiveTimeout(-1); Yeah, this is a bad idea. The session will never go away by itself. This *requires* the user to press a logout button, and for you to explicitly call session.invalidate(). Users frequently do not log themselves out, and their sessions will never die. You will eventually run out of memory. If you need a long timeout, just make it really long (like a couple of hours). There's usually no good reason to make it -1. PS is the session time out linked wirth inactivity? My session attribute only persists as long as I am using the app. That's exactly how the 'inactive' timeout works. -chris signature.asc Description: OpenPGP digital signature
Re: OracleConnectionPoolDataSource creates too many connections
Rudi,
I have two things to add that nobody seems to have mentioned.
In my LoginServlet, I create a new PooledConnection, which I add to the
Servlet Context:
PooledConnection pc = ConnectionFactory.getInstance.getPooledConnection();
ServletContext ctx = getServletContext();
ctx.setAttribute(pooled_conn, pc);
Gah! Why are you putting a database connection into the application
context? This sounds like a concurrency nightmare! I think you want to
put the /pool/ into the application scope, not a single connection.
Connection con = pc.getConnection
//do a few things with the connection
try{
if (con != null){
con.close();
} // I'm assumingthis returns the connection to the Pool
}catch(SQLException sqle){
sqle.printStackTrace();
}
You need more try/catch blocks. conn.close should /always/ be in a
finally block:
Connection conn = null;
// Declare your statements and resultsets, here, too
try
{
conn = // whatever
// Do stuff with connection
}
finally
{
// Close your statements and result sets, here, too
if(null != conn)
try { conn.close(); } catch (SQLException sqle)
{ /* log this exception somewhere */ }
}
Hope that helps,

Why are you looking in the freebsd directory for cygwin binaries? For cygwin i don't know if i must use a win32 mod_jk.dll (version 1 or 2) or build a mod_jk.so. It will be a .dll file.

JSP whitespace removal
Hi We want to achieve a 10-15% data reduction of the HTML being served by our webserver (generated by JSP pages). This will have an impact on our bandwidth charges from our ISP... We can achieve this by by simply removing all the \n\r, \t characters and replacing repeated occurences of(double space) by (single space). But we don't want to do this in our source JSP files as they will become unmaintainable/unreadable. eg table tr tdColumn 1/td tdColumn 2/td tr /table (69 characters) becomes tabletrtdColumn 1/tdtdColumn 2/tdtr/table (57 characters), that's an 17% saving for that text block... I know that we could: i) write/implement a filter to process the outputstream - BUT we use OSCache (www.opensymphony.com) to cache (included) JSP pages, and we don't want to reprocess cached data using another filter. ii) use a script to transform or preprocess our JSP pages before they are deployed - simple, but may have code breaking (between dev and live system) or maintenance implications? iii) create a tag library to process a text block (or another JSP), BUT we've heard a rumour that taglibs can be inefficient (is that true?) Question: is it possible to use a directive in a JSP page to force the compiler to remove these characters to achieve our desired data reduction? Are there any other techniques or solutions that anyone else is using? Thanks John Sidney-Woollett - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I cannot help you on this, but you should realise, that if you archive to reduce you jsps output by 10%, this will affect you traffic only by about 2%.

We have a traffic shaper so we can control the amount of bandwidth (Mbit/sec) we use for outbound traffic, and we're trying to cram as much data per second as we can within our (managed/shaped) limit. In fact it seems that (gzip) compression is a better strategy for HTML/CSS pages because it offers compression of 80%. But it's still better to compress the pages after you strip the whitespace for a small final text size. Unfortunately we also have a lot of graphics (but at least once they are cached by the browser) then we only have to deal with a HEAD request to see if they have been updated...

Re: JSP whitespace removal
the reduction depends on your html right? if you use a lot of tables, you're likely to see 5-10x compression. The easiest trick is to save a couple of your biggest pages and zip them up. Compare the file size. Now, if you have regular log reports, you can see which pages get requested the most and how many bytes it is. from that you can get a fairly accurate estimate in total bytes sent per week/month. Stripping out carriage returns and tabs most likely won't give you as much as compression. Here is an easy way to test it on other sites. Load a site that uses gzip with a browser that support gzip and without. Compare the actual bytes sent and how much faster the page loads. I know from first hand experience verizon SuperPages reduced 60K+ to 6K when they started using compression. The user's perception is the page was 2-4x faster. peter lin John Sidney-Woollett [EMAIL PROTECTED] wrote: Peter Lin said: have you tried turning gzip compression? that should produce similar bandwidth savings to stripping out extra carraige returns and double spaces.

Blocking SNMP calls?
I have an app. that uses Adventnet SNMP classes. If I perform a snmpSet() call from inside a Tomcat or JBoss server, my application gets a timeout error (I mean, the application is unable to communicate with a remote network device via SNMP and the SNMP error is Request Timed Out to w.x.y.z). But if I run the exact same class I wrote, as a Java console application, from the same host, it works perfectly. Any ideas? Best regards, E.

Re: Where to store log files from packed WAR file apps
You should never log to within the directory structure of your webapp if you
want your app to be portable. Provide configuration in web.xml as to where you
want the log file to go which an admin can override via proprietary
configuration. For instance, in Tomcat...
Context ...
Parameter name=log4j-log-location value=C:\logs override=false
description=Location for logs to be written/
/Context
Then in your Log4j initialization, use value of the log4j-log-location
context-param and set a system property with that value to a name that you
reference in your log4j.xml file such as
appender name=File class=org.apache.log4j.RollingFileAppender
param name=File value=${log.location} /
..
..
..
/appender
Or, check out the logging-log4j-sandbox project and grab the alpha_2 (I think
that's the tag name) tag. Then look into ServletContextLogAppender which will
allow you to specify this in log4j.xml
appender name=ServletContext
class=org.apache.log4j.servlet.ServletContextLogAppender
param name=servletContextPath value=/mycontext /
layout class=org.apache.log4j.PatternLayout
param name=ConversionPattern value=[%-5p][%-8.8t]: %39.39c{3} -
%m/
/layout
/appender
The output will be routed through your server's context.log() mechanism. In
Tomcat, just set up
Context path=/mycontext docBase=mycontext.war
debug=5 reloadable=true
Logger
className=org.apache.catalina.logger.FileLogger
prefix=localhost_mycontext_servlet_log.
suffix=.txt
timestamp=true /
/Context
Now you don't need to configure any file to do the logging. It will just show
up in your container's log directly which you know for a fact will exist and the
container will create it for you.
Or, use Chainsaw2...
http://logging.apache.org/log4j/docs/chainsaw.html

Quoting Harry Mantheakis [EMAIL PROTECTED]:
Hello
Now that I've got my Ant build/deploy scripts working nicely, I'm tempted to
start running my applications out of packed WAR files.
I cannot figure out if there is a *portable* way to specify paths for where
my Log4J log files should be saved.
I assume I could use the 'catalina.home' property to save the logs under the
Tomcat installation directory - but that's Tomcat specific.
Has anyone got around this, somehow, or is it a case of getting Ant to glue
things with some hard-coded values at build time?
Many thanks for any contributions.

default mime type for tomcat 5
I have some plain text files that are formated but when tomcat 5 serves the pages it loses all formating. This only happens on older browser such as netscape 4.79. I assume that tomcat sets the default mime type to text/html but I need it to be text/plain. Nathan - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: What is the problem with tomcat 5.0
Hello, Joao: jmx.jar contains javax/management/ListenerNotFoundException.class and (for me) jmx.jar is in $TOMCAT_HOME/common/lib; perhaps it's not installed on your system. Here's a very simple yet useful Bourne shell script: for jar in `ls *jar` do echo checking $jar... jar tvf $jar |grep -i listenernotfoundexception done btw: you can install either Cygwin on a Windows PC or uwin (if you prefer ksh)...

RE: What is the problem with tomcat 5.0
Hi, What jars that didn't ship with tomcat are in your runtime classpath? I;ve nothing set on my classpath. I saw that tomcat override whatever you set . The script setclasspath.sh does the job. It does this. I'm aware of this script and what it does -- thanks ;) But that's not what I asked. By what's in your runtime classpath, I mean exactly that: your runtime classpath includes the WEB-INF/classes directory of your webapp, WEB-INF/lib, common/lib, shared/lib, the bootstrap classloader, system endorsed directories, and others possibly. (See tomcat's classloader howto if you're not sure what I'm talking about). If one of these directories that comes before common/lib in the runtime classpath has an older JMX jar without the exception, you'd get the error you're getting.

Hi guys, I'm pretty much a newbie when it comes to configuring Tomcat, and also with building JSPs, although thanks to the useful examples and documentation, I've been able to pick it up pretty quickly. Anyways, I am interested in using the utilties provided in the commons-fileupload-1.0.jar file. I downloaded it to the $CATALINA_HOME/common/lib folder. When I tried to import org.apache.commons.fileupload.*, I get an error stating that the package doesn't exist.

RE: FAIL - Application at context path /[context] could not be started ???
Hi, The error, not explained in the Manager documentation anywhere BTW : FAIL - Application at context path /foobar could not be started Errors aren't typically explained in the documentation, as we rely on stack traces and other information to diagnose and correct problems. Feel free to inspect the relevant code, document the possible error messages, and submit a documentation enhancement patch. The answer is not obvious to me. Nothing seems to be logging anywhere for me to debug it. A few general tips for cases like this: - Add debug=99 to the Engine and Host elements of your server.xml file. This will output more information. - Try to deploy the WAR by simply copying it to the webapps directory (assuming autoDeploy is on for your Host). Do any errors occur? If so, fix these before you try ant/manager deployment. - Comment out/remove all unneeded webapps and elements from server.xml, making your deployment as simple as possible. - If you're still having trouble, start stripping things that execute on startup from your web.xml: filters that do stuff on init(), servlets that have load-on-startup enabled, listeners, etc. Yoav Shapira This e-mail, including any attachments, is a confidential business communication, and may contain information that is confidential, proprietary and/or privileged.

Re: cross context include
I've been struggling with the same problem. I read the bug report, but it only adresses part of the problem, the part that doesn't retrieve the session properly. I actually patched the code independently and have discovered another problem, that somehow sessions are either getting lost or mixed up when you do cross context imports in at least one advanced scenario : 1) page Z in context 'a' import a page X from context 'b' 2) page X in context 'b' imports a page Y in context 'a' in this case, the session that was created when you import page X in context b is the session that's available in page Y in context a. here's my test case --- test_page1.jsp ( context '/profile' ) : %@ taglib prefix=c uri=http://java.sun.com/jsp/jstl/core; % Test of cross context imports : % request.getSession().setAttribute(test_attrib, 12345); % % out.println(test_attrib in ( test_page1.jsp ) is + session.getAttribute(test_attrib) ); %br/ % out.println(session id ( in test_page1.jsp) is : + request.getSession().getId() ); % br/ c:import url=/test_other.jsp context=/ / test_other.jsp ( context '/' ) : %@ taglib prefix=c uri=http://java.sun.com/jsp/jstl/core; % % request.getSession().setAttribute(test_other_attrib, 54321 ); % % out.println(test attrib ( in test_other.jsp ) is : + request.getSession().getAttribute(test_attrib) ); %br/ % out.println(test other attrib ( in test_other.jsp) is : + request.getSession().getAttribute(test_other_attrib) ); %br/ % out.println(session id ( in test_other.jsp) is : + request.getSession().getId() ); % br/ c:import url=/test_page2.jsp context=/profile/ test_page2.jsp ( context '/profile' ) : %@ taglib prefix=c uri=http://java.sun.com/jsp/jstl/core; % % out.println(test_attrib ( in test_page2.jsp ) is + session.getAttribute(test_attrib) ); % br/ % out.println(test other attrib ( in test_page2.jsp) is : + request.getSession().getAttribute(test_other_attrib) ); % br/ % out.println(session id ( in test_page2.jsp) is : + request.getSession().getId() ); % br/ The output i get when I hit test_page1.jsp is : Test of cross context imports : test_attrib in ( test_page1.jsp ) is 12345 session id ( in test_page1.jsp) is : 2796EBFF6C413841B7B2D496D7E8FD3F test attrib ( in test_other.jsp ) is : null test other attrib ( in test_other.jsp) is : 54321 session id ( in test_other.jsp) is : 2796EBFF6C413841B7B2D496D7E8FD3F test_attrib ( in test_page2.jsp ) is null test other attrib ( in test_page2.jsp) is : 54321 session id ( in test_page2.jsp) is : 2796EBFF6C413841B7B2D496D7E8FD3F The output I get when i hit test_other.jsp is : test attrib ( in test_other.jsp ) is : null test other attrib ( in test_other.jsp) is : 54321 session id ( in test_other.jsp) is : 55B2068D3011D727DF15068ADAD713E2 test_attrib ( in test_page2.jsp ) is null test other attrib ( in test_page2.jsp) is : null session id ( in test_page2.jsp) is : 55B2068D3011D727DF15068ADAD713E2 the output that i get when i hit test_page2.jsp : test_attrib ( in test_page2.jsp ) is 12345 test other attrib ( in test_page2.jsp) is : null session id ( in test_page2.jsp) is : 2796EBFF6C413841B7B2D496D7E8FD3F Any hints on how to resolve it?

Maybe I'm too close. Nothing is working now. Not the ant task not the manager interface. Nothing. The answer is not obvious to me. Nothing seems to be logging anywhere for me to debug it.

RE: Serialization issue
Hi, What is the CoyoteWriter object I keep running inot, and how can I mark it as transient? It's the HTTP connector's writer, and you can't mark it as transient. You would have to manually remove non-serializable attributes from a copy of the Map before you try to serialize the copy.

Can't access session id
I need to access the session id from within a JSP and pass it, explicitly,
to a Flash-based client.
I am using the following code fragment as part of my JSP, but the value
returned for the session id is always blank.
Am I doing something wrong?

Re: Serialization issue
Right now I get the exception even when I try to serialize a HashMap I just created, without any data in it. I would guess that any request parameters stored in the map returned by request.getParameterMap() should be serializable right? I don't understand how, f I'm serializing a new serializable object, the CyoteWriter get's involved.

Re: reclaiming memory problem PS
Hello, and thank you for that,
Yes, I am timing the session out and trying to handle the result. I have:
HttpSession objSession = request.getSession(true);
String sessionStatus = (String) objSession.getAttribute(sessionStatus);
if (sessionStatus == null) {
forward off to JSP
}
Now sessionStatus is getting caught fine, but when I try and redirect to a JSP after
that, nothing happens. I originally tried mapping.findForward (Struts),
response.sendRedirect and forwarding using RequestDispatcher. I have tried
getSession(true) and false. What implications (if any) does session timeout have in
terms of forwarding after the session is invalidated?
Many thanks
G.
Jerald,
session.setMaxInactiveTimeout(-1);
Yeah, this is a bad idea. The session will never go away by itself. This
*requires* the user to press a logout button, and for you to explicitly
call session.invalidate(). Users frequently do not log themselves out,
and their sessions will never die. You will eventually run out of memory.
If you need a long timeout, just make it really long (like a couple of
hours). There's usually no good reason to make it -1.
PS is the session time out linked wirth inactivity? My session
attribute only persists as long as I am using the app.
That's exactly how the 'inactive' timeout works.
