Tomcat thread blocking
Hi, I've recently observed a scenario in Tomcat 6.0.13 64-bit under SUN JDK 1.6_03 (x64 Windows platform), where a large number of threads show a status of BLOCKED. Can someone please advise the easiest and most effective way of helping identify the original cause of the block?or have I just opened up a can of worms?! The behaviour is not something I can replicate so I need a method for in situ investigation, before I have to restart Tomcat to restore service (after a while Tomcat consumes too much CPU and becomes unresponsive) Any pointers would be much appreciated.

Given http://tomcat.apache.org/security-6.html, downgrading is really bad advice. Added to which, it won't change anything. I think a wrapper represents a servlet instance... (guess)... and 253,020 sounds like a huge number. It is, and my previous on this thread explains it. I think you should be concerned... whether it is a TC issue or a Webapp issue you only going to discover if you try a few TC's that have been around for a while... Trying different Tomcat versions isn't going to help. I think document your entire system the JRE as well... and if it does not show in an earlier TC, let the dev group know No need, we already know. As would you if you had a) used Google, b) looked in Bugzilla or c) searched the archives for this list. The thing that would tell you that there is definitely an issue, is if you watch the memory during the load test... if thats getting less and less with time its crashing... I think you mean free memory here. Increasing memory usage during a load test isn't necessarily an issue as long as it levels off eventually. If you suspect a memory leak the only real way to be sure is to use a profiler and look at the actual usage. It seems to be holding servlets in memory and making new ones... it may not be TC... you now have to experiment No need to experiment. A little research was all that was required.

1) Which is faster JNDI Based Connection pool / ordinary JDBC based connection / close ? JNDI based connection pool.

j_security_check requires session
I am having a problem posting credentials to j_security_check for form-based authentication. It seems that tomcat expects that I already have a session established before posting the username and password. If I don't already have a JSESSIONID cookie, j_security_check returns a 408. Unfortunately, I have another application attempting to talk to this one that requires that the first thing it does is post credentials to the j_security_check, so I have no mechanism of hitting another page first to establish a session. This mechanism worked fine with BEA Weblogic, but it seems that tomcat's handling of j_security_check is different. Does anyone know of any options to modify the behavior of j_security_check so that it would just do the authentication and establish the session in one shot at the time of the POST request? Thanks, Paul

Re: Some Prilim questions
I have no idea where you are going with this ... it makes no sense to the original question. If you mean the webapp is hosted on a geographically distant place from the database server, then you'll have latency like no tomorrow regardless of whether a database pool is used or not. The point and reason developers use a database pool is the pooled connections are already formed. Getting a connection is just borrowing it from the pool and closing is just returning it after your all done. Pooling makes sense because connection handshaking and authentication is done once on the first call for a connection. Each successive borrow of that connection is ready immediately without any overhead associated with forming a new one. --David Martin Gainty wrote: the referenced jndi lookup in the webapp context is located in India and the DB is in Ithaca NY the Indian JNDI lookup is considerably slower than 'ordinary JDBC connection' from NY With Warm Regards Martin __ Disclaimer and confidentiality note Everything in this e-mail and any attachments relates to the official business of Sender.

Subject: manipualting a select list from within an event handler
Manipulating checkboxes from withing an onchange event handler works but
I'd like to manipulate a select list like in this code example,
but without luck? I'd appreciate some little help, that would be
fantastic.
Thank's for some input here ;)
kind regards,
Robert
function CheckAuswahl(currForm)
{
a = document.form_addresses.form_protocol.value;
if(a==33554432)
{
for(var x=0; x currForm.elements.length; x++) {
var y = currForm.elements[x];
y.checked = currForm.form_exch_enabled.checked;
if (y.name == form_exch_enabled) {
y.checked = true;
//alert(y.name);
}
if (y.name == form_exch_name) {
if(y.value == ) {
y.value = ggg;
}
}
if (y.name == form_exch_pass) {
if(y.value == ) {
y.value = ggg;
}
}
if (y.name == form_permitted_rcv) {
//var a=y.createElement('option');
//a.name=TEST;
//y.focus();
y.add('Test',null);
alert(y.size);
}
}
}
}
td%=Label_Protocol%/td
td
%
int intProtocol = Integer.parseInt(Value_Protocol);
%
select name=form_protocol
onchange=CheckAuswahl(this.form) %=Label_State%
option % if ( intProtocol == sysProtocol_ZModem) {%selected%}%
value=%=sysProtocol_ZModem%
%=Value_Protocol_ZModem%/option

Robert just looking at it... you passing a form element and the select in
not in one...
Have a look at this example...
http://www.mredkj.com/tutorials/tutorial005.html
and Javascript is a mine field so get yourself FireFox at least and the
plugin so you can see the whole DOM and what params are available...
Then make it work just in a normal HTML editor... then stick it in JSP...
else its difficult...
Like for example... look at that example... can you see they making special
allowances for IE... because microsoft are on their own mission.
Google for Javascript stuff... W3 Schools is quite good, but there are tons
of tut sites out there
Javascript is something you really want to use in moderation... its not easy
getting it cross browser compat...
And you'll get crapped out if you ask here ;)
Kinda fun though ;)

Tomcat unable to find jars when deployed from Eclipse
I'm running Eclipse 3.4 with Tomcat 6.0.18 configured as a server. After a bit of consternation, I was able to see my test html and jsp files. However, for some reason, my servlet doesn't see the jar files it needs unless I put them in WebContent\WEB-INF\lib. Now I've already defined them in Eclipse and checked the export option. So why doesn't that work? Am I doing something wrong, or am I stuck with the only solution being to put them in the WebContent\WEB-INF\lib dir? TIA. Bai Shen

Am I doing something wrong, or am I stuck with the only solution being to put them in the WebContent\WEB-INF\lib dir? The alternative is to go to the Java EE Module Dependencies page of the project's properties. You should see your build time jars listed there. Check them to include them in the runtime classpath. These jars will then be included in the WEB-INF/lib of the Web application when the project is published to a server or exported as a war. Cheers, Larry TIA.
