RE: Trying to work with JDBC OCI
I still think your jdbc-url is wrong. In my opinion you have to give a tnsname
for the oci driver and hostname+port+sid for then thin driver.
Have you tried the examples given in
http://otn.oracle.com/tech/java/sqlj_jdbc/pdf/a96654.pdf
on Page 52 and 53?
For the examples it is enough to have exported LD_LIBRARY_PATH containing
$ORACLE_HOME/lib and CLASSPATH containing the classes12.zip from the oracle
9i client-installation ($ORACLE_HOME/jdbc/lib).
-- Original Nachricht --
It is most definitely a native library location problem not a CLASSPATH
problem.
2) I have put LD_LIBRARY_PATH=$ORACLE_HOME/lib.
Where have you set this variable. It should be visible to the run.sh script.
Also, make sure that $ORACLE_HOME is also set.

isapi_redirect multithreading problem
Hi All ! I'm running Tomcat4.01 on IIS 5.0 using isapi_redirect.dll. Here is my server.xml for APJ connector: Connector lassName=org.apache.ajp.tomcat4.Ajp13Connector port=8009 minProcessors=5 maxProcessors=75 enableLookups=true acceptCount=50 debug=0 connectionTimeout=-1/ The problem is, that when using isapi_redirect i don't see ANY multithreading (it looks like isapi_redirect queing requests). Can anyone help me ? Thanks When a password just isn't secure enough, and email confirmations don't quite cut it, You need Voice Authentication. You need SentryCom.

Getting mod_webapp - should I give up?
So, nobody can help me to build mod_webapp, and there is no rpm of it to download. Does this just mean that it can't be built?

RE: Getting mod_webapp - should I give up?
As far as I can see, mod_webapp was designed to be an easier to setup way of integrating apache and tomcat and it succeeds in this on windows for apache 1.3 and tomcat 4.0x. However, it will serve all content from a directory you configure it for from tomcat whereas mod_jk* will leave html, jpg, gif etc to Apache. The way round this is to have your pics and static pages in a different location that is served by Apache alone and referenced as /static/xxx or similar but this then loses the convenience of a single war file containing everything needed for the application (it can even include a mod_jk conf file which can help with mapping servlets without the need for the ugly /servlet/servlet_name of the auto-created jk conf filers of tomcat 3) Worse than the above, I have found that large requests or frequent requests or just at random cause tomcat to give an error about the client terminating or some such and hang. With mod_jk this doesn't happen (or with tomcat standalone).

Re: mod_auth_ntdom
Few weeks ago I was facing similar problem (but not with NT auth!). The problem was in browser (MSIE6) which was not correctly accepting cookies (settings were OK).

performance problem
Hello! I have extremly performance problem! I send a http-request to Tomcat, which forwards the request over RMI to a business logic. This sends back a XML with the templates to include and values to place in the templates. This process takes about 100 - 400ms (not very fast but ok) After received the answer, Tomcat processes the XML via a few custom tags to include templates and write text values in this templates. A small (3k) template needs about 500ms to display. A little bit larger one (9k), about 20 sec For the time the HTML is created (resolving custom tags) , Tomcat is using 100% of the CPU! Looking at my log files, it seems that the HttpProcessor-Thread on Tomcat is blocked by another tomcat thread. In intervalls of about 4sec the HttpProcessor-Thread can process a little bit of its code and than is blocked again. Or tomcat is not able to hold the request object and writes it somewhere to disk. So every 4sec it has to read or write the information needed for this process to disk. Must I increment the cache for the context or the server? But where and how? Here a snippet of my log-file: 2002-08-14 15:49:36,403 DEBUG [HttpProcessor[8080][3]] obsession.juice.out CmsTag doStartTag - CurrentNode = [Element: pers_klassifikation/] looking for child [pers_klassifikation_item] 1 of 2 2002-08-14 15:49:40,068 DEBUG [HttpProcessor[8080][3]] obsession.juice.out SelectTag getOutputText - looking for parent the JSP-Code involved in this 4 sec: tr tdcms:text name=pers_klassifikation data=name//td td select size=1 class=long name=cms:text name=pers_klassifikation data=parameter/ cms:enter_area name=pers_klassifikation cms:area name=pers_klassifikation_item option value=cms:text name=pers_klassifikation_item data=value/ cms:select name=pers_klassifikation_item output=selected/cms:text name=pers_klassifikation_item//option /cms:area /cms:enter_area /select /td /tr the XML needed to populate the custom tags: pers_klassifikation name=Klassifikation parameter=fk_klassifikation_id validate=int range=1:100 mandatory=0 id=44 value=2 pers_klassifikation_item value=1Lead/pers_klassifikation_item pers_klassifikation_item value=2Honorar/pers_klassifikation_item /pers_klassifikation 4sec to know if the option tag is selected or not!

Re: mod_auth_ntdom
| But I don't exactly get why u use the response.encodeURL method, can u | elaborate a little bit on that? Well... Try to search some info about cookies and session IDs (java, php or else; it does not matter)... But for now, very briefly: In HTTP session exists only at server side (together with all other session objects). Client (browser) only receives sessionID and with this ID it identifies itself for a particular session. When I authenticate in Tomcat, I send my login/pass information, and server returns my SessionID as cookie. In every (!) HTTP request are cookies sent together with request. And if server finds client's SessionID, it does not need to authenticate user again... Anyway: If your browser is not accepting cookies (or evaluation is incorrect which was the case of my IE6) server is not able to set the cookie with session ID. In Java we should use response.encodeURL method which: Encodes the specified URL by including the session ID in it, or, if encoding is not needed, returns the URL unchanged. The implementation of this method includes the logic to determine whether the session ID needs to be encoded in the URL. For example, if the browser supports cookies, or session tracking is turned off, URL encoding is unnecessary. (taken from Tomcat 4.0.3 javadocs). So in usual case, the method response.encodeURL(myfile.jsp) returns myfile.jsp. But if there is a problem with accepting cookies, this method returns something like that myfile.jsp;J_SESSIONID=123456789 This is called URL rewriting. But in your case you should examine your mod_auth settings (is it stable enough???). If the authentication is done by Apache, some things may be wrong there. I have seen some URL rewriting directive in Apache, but I have never tried what you are doing now. First try to access a single page (like blank.html)... You should need to login once. Than try to access a page with one other link (an image od CSS). If you need to login twice, your problem is 100% in user/login settings.

Re: performance problem
before you go exploring other ideas, try jasper2 from the latest beta 4.1.9. if you have nested tags, most likely you're suffering from jdk bug with deeply nested try/catch. I would bother looking into other things until you've atleast tried jasper2. peter Alessandro Di Maria wrote: Hello! I have extremly performance problem! I send a http-request to Tomcat, which forwards the request over RMI to a business logic. This sends back a XML with the templates to include and values to place in the templates. This process takes about 100 - 400ms (not very fast but ok) After received the answer, Tomcat processes the XML via a few custom tags to include templates and write text values in this templates. A small (3k) template needs about 500ms to display. A little bit larger one (9k), about 20 sec For the time the HTML is created (resolving custom tags) , Tomcat is using 100% of the CPU! Looking at my log files, it seems that the HttpProcessor-Thread on Tomcat is blocked by another tomcat thread. In intervalls of about 4sec the HttpProcessor-Thread can process a little bit of its code and than is blocked again. Or tomcat is not able to hold the request object and writes it somewhere to disk. So every 4sec it has to read or write the information needed for this process to disk. Must I increment the cache for the context or the server? But where and how?

Re: Hooking up Tomcat to Apache
See below Peter Alvin wrote: Tomcat is running fine in standalone mode but I'm having difficulty hooking it up to Apache. I've configured Tomcat's server.xml file and I have an include file in Apache's httpd.conf file that points to a copy of the auto -generated tomcat-apache.conf file (where I've corrected the path to the mod_jserv.so module). When surf to www.mydomain.com/appName I get a Cannot find server page (interestingly, not a 404). If you don't mind, I have a few questions. 1) Fact1: When tomcat runs in standalone mode, its default port is 8080. Fact2: my auto-generated tomcat-apache.conf file has the line ApJServDefaultPort 8007. Question: Does that mean I have to manually start Tomcat on 8007 (instead of 8080) in order to handle the requests from Apache? No. 8007 is not the same as 8080 (obviously). 8080 is an HTTP connector that you can get to through a browser. 8007 port is for the AJP connector to send requests over. They must be different. You should see the 8007 port in your workers.properties file for the AJP connector. 2) Does the adaptor, mod_jserv, open up a TCP connection to Tomcat in order to pass requests? I guess so. This sounds inefficient. That's the 8007 port. 3) There is another line in the tomcat-apache.conf file that states ApJServManual on, which, according to the manual says this: Instruct jserv not to start the Tomcat process. Automatically starting Tomcat is not implemented yet. If that is true, how do I configure Tomcat to start automatically along with Apache? /etc/inittab for starting during system boot? My overall goal is to have only *.htm files (mydomain.com/fileXYZ.htm) handled by Tomcat. I think this is a typo. Tomcat should be handling the .jsp files and the HTML files should be left to apache to handle.

Re: Getting mod_webapp - should I give up?
I had a very similar experience and came to the the same conclusion though I was using Tomcat 4.04. This is why I've been trying to get CGI's under Tomcat standalone to work, unfortunately I haven't been able to find out any information on this anywhere. (And if YOU know something I'd appreciate hearing of it! - see my earlier post titled: 'Do included CGI's work with Tomcat' the problem seems to be that you Tomcat doesn't process included CGI's) As far as I can see, mod_webapp was designed to be an easier to setup way of integrating apache and tomcat and it succeeds in this on windows for apache 1.3 and tomcat 4.0x. However, it will serve all content from a directory you configure it for from tomcat whereas mod_jk* will leave html, jpg, gif etc to Apache. The way round this is to have your pics and static pages in a different location that is served by Apache alone and referenced as /static/xxx or similar but this then loses the convenience of a single war file containing everything needed for the application (it can even include a mod_jk conf file which can help with mapping servlets without the need for the ugly /servlet/servlet_name of the auto-created jk conf filers of tomcat 3) Worse than the above, I have found that large requests or frequent requests or just at random cause tomcat to give an error about the client terminating or some such and hang. With mod_jk this doesn't happen (or with tomcat standalone). So, nobody can help me to build mod_webapp, and there is no rpm of it to download. Does this just mean that it can't be built? I don't remember where I read that mod_webapp was the correct way to integrate Apache2 and Tomcat4. The documentation is a bit fragmented. Is mod_jk* the true way to do this? If so, could someone give me a URL to a definitive page that says this and how to get/build it? I just want to integrate Apache2 and tomcat4, not do anything special. About a year ago I did successfully integrate Apache1 and tomcat, but I haven't worked with tomcat since then.

Possible bug: wrapped requests and jsp:include
Hello, I've found behaviour which might be a bug in Tomcat 4.0.4. I have a filter that wraps a request using the correct way (HttpServletRequestWrapper.) The wrapper overrides getParameter (etc.) The wrapped request then goes to a JSP, one.jsp. one.jsp includes another JSP like this: jsp:include page=/two.jsp jsp:param name=foo value=bar / /jsp:include The problem is that two.jsp only sees the parameters provided by the wrapper; it can't see the parameter foo. i.e., in two.jsp: %= request.getParameter(foo) % is null. This seems incorrect to me - surely the parameters set via jsp:param should override any set by the wrapper. I can't find anything explicit in the spec, though. It sounds like for jsp:include, Tomcat 4.0.4 is invoking methods on the internal HttpServletRequest implementation, rather than what I would expect, which is to use another wrapper around whatever HttpServletRequest object the JSP/servlet is currently processing. So is this a bug? I can send a simple webapp demonstrating this to anyone interested. Robert Tansley / Hewlett Packard Laboratories / Tel.

Re: Enterprise Java Beans (EJB)
EJB provides a way to easily encapsulate business logic and reduce complexity by moving some difficult functionality/designs into deployment instead of development. Transaction requirements defined in the deployment of the EJB beans as opposed to part of the development of the EJB beans. (And they are easy to migrate/scale to many computers based on deployment configuration, again, making that task easier for developers since the programmer does not need to do anything special to achieve this. Session beans contain the business logic (Servlets call them) Entity beans persist the info to the database. (Session beans call them) Message beans respond to JMS queues/topics. In reality, EJB is simply another design pattern... one that was over-hyped by the vendors, but can provide flexibility needed in some cases.

Re: Enterprise Java Beans (EJB)
No Here is what: Bean (formBean in Struts for example) delegate to DAO for CRUD (Insert,Read, Update,Delete to SQL DB) and persistence, done by DAO. DAO is an interface. The interface could be, inside of the DAO and not known to bean (formBean), implemented inside of the DAO a few different ways. You could have a DAO implementation using EJB or Castor or Jakrta OJB, or RowSet (I use RowSet). If you have an interface, such as DAO pattern, you could change the implementation and not affect the rest of your application. So ... make your persistance/CRUD and interface. This lets you change how it does CRUD. You should be able to switch from JDO to EJB or OJB to RowSet/ResulSet. If you have to refactor the whole application to junk EJB or JDO... that would not be great. A simple interface would do ya. v.

RE: Getting mod_webapp - should I give up?
So, I'll forget about mod_webapp because no one knows how to build it and the people who built it once say that it doesn't work well anyway. So, I'll try mod_jk, though I'm concerned that it's marked as deprecated in the apache bugzilla. Now, I just need a URL of some instructions for building mod_jk, because there are no binaries or rpms for mod_jk either, at least not for Tomcat4. Note that I'm trying to use Apache2. On Thu, 2002-08-15 at 10:16, John Burgess wrote: As far as I can see, mod_webapp was designed to be an easier to setup way of integrating apache and tomcat and it succeeds in this on windows for apache 1.3 and tomcat 4.0x. However, it will serve all content from a directory you configure it for from tomcat whereas mod_jk* will leave html, jpg, gif etc to Apache. The way round this is to have your pics and static pages in a different location that is served by Apache alone and referenced as /static/xxx or similar but this then loses the convenience of a single war file containing everything needed for the application (it can even include a mod_jk conf file which can help with mapping servlets without the need for the ugly /servlet/servlet_name of the auto-created jk conf filers of tomcat 3) Worse than the above, I have found that large requests or frequent requests or just at random cause tomcat to give an error about the client terminating or some such and hang.

Checking Tomcat's Memory
Greetings! I'm running Tomcat 4.0.4 (w/ JDK 1.4, WinNT/2K) and would like to know how to check Tomcat's memory settings. I've defined an environment variable (in Windows) like so: CATALINA_OPTS=-server -Xms1g -Xmx3g and from reading previous e-mails on this list, this should set the JVM min and max heap size, yet how can I verify this? I'm currently testing a program that takes a considerable amount of memory, and after getting so many thousand requests (and storing a considerable amount of data in memory), the performance becomes horrible (3 to 4 times CPU usage, possibly due to gc looking for more memory?). I suspect the memory settings because when the CPU usage starts to spike, the memory usage tops off and does not appear to go up at all (when it most likely should continue to go up).

I can see it replacing Entity beans, and the DAO layer uses entity beans; then your session beans would talk to the DAO layer which did all (only?) persistance.

So, it doesn't replace all of EJB, just EJB's entity beans, right? However if you find EJB's slow and not scalable, than you would implement DAO another way. But since you would pull out Enity beans out, than there is not much reason to keep Session beans. You could just put regular form bean or java bean in session in some cases and get rid of EJB server and just use TomCat or Resin. (most app. servers have other ways to fail over). If you have reson to use session EJBs that use them, but I can think of no reason anyone would want to uses Enity EJB.

example, by creating a 100 * 1000 array of Integer objects.
Integer[][] hugeArray = new Integer[100][1000];
for(l = 0; l 100; l++)
{
for(l2 = 0; l2 1000; l2++)
{
hugeArray[l][l2] = new Integer(l2);
}
}
- Start the server with this app running, but not your other apps.
(Assuming ROOT, examples, tomcat-docs etc take very little runtime
memory). Make sure you trigger the above code, and see that it runs
without an OutOfMemoryError. You've just verified the minimum setting.
- Modify the above code to 300 * 1000, again run it, verify that it
*does* generate an OutOfMemoryError. Then you will have verified the
-Xmx setting.
- Obviously, I used perfectly nice round numbers in the above code. Due
to internal tomcat stuff, other webapps, runtime overhead, JVM overhead,
etc, the actual numbers will be lower.
- You can also verify within the program how much RAM hugeArray took up
by trying something like:
System.gc();
long memBefore = Runtime.getRuntime().totalMemory();
hugeArray = null;
System.gc();
long memAfter = Runtime.getRuntime().totalMemory();
long hugeArrayMemory = memAfter - memBefore;
- As always, stuff like the above should be run several times and
averaged, for a more reliable predictor. System.gc() is not guaranteed
to run, much less do a full GC, etc etc I assume you already know all
about that.
Maybe this will help ;)
You can also try MemoryMonitor from these guys:
http://www.spywindows.com/PAGE1/SOFTWARE.HTM
I've used it in the past, it's decent. But I trust the above approach
more.

I'm currently testing a program that takes a considerable amount of
memory,
and after getting so many thousand requests (and storing a considerable
amount of data in memory), the performance becomes horrible (3 to 4
times
CPU usage, possibly due to gc looking for more memory?). I suspect the
memory settings because when the CPU usage starts to spike, the memory
usage
tops off and does not appear to go up at all (when it most likely
should
continue to go up).
Suggestions appreciated!

RE: Tomcat 3.3.1
It would seem that the JSPs are being handled as static files and not being handled by the JspInterceptor. I would recommend doublechecking how you have configured your Tomcat and use log output (set non-zero debug levels as needed) to see why it is behaving the way it is.

Re: Enterprise Java Beans (EJB)
However if you find EJB's slow and not scalable, than you would implement DAO another way. But since you would pull out Enity beans out, than there is not much reason to keep Session beans. You could just put regular form bean or java bean in session in some cases and get rid of EJB server and just use TomCat or Resin. (most app. servers have other ways to fail over). If you have reson to use session EJBs that use them, but I can think of no reason anyone would want to uses Enity EJB. Well, this isn't the best forum for this, but Entity beans have a purpose, just the vendor's over-hype of having people use them everywhere. The strongest reason to use EJB entity beans is the deployment configuration that you can set, and change (in certain cases) with a running ejb cluster. I can't speak for DAO in this way, but for TopLink and Castor, that is not really possible. (Currently. I'm working on Castor :-) Not to mention, container managed persistance takes much away from the developer, and gives it to the admin; which can be bad, no doubt. Eh, really it boils down to architecture. Each architecture has a their limitations. DAO sounds nice, but like EJB, its 'yet-another-layer'; abstraction to provide for flexibility. It may be good (again, I never used it) but its still a layer. If you don't need that flexibility, then its a cost/liability.

RE: Checking Tomcat's Memory
Heh, the answer to that is kind of. I can actually do roughly 250 TPS (at least according to a tool I'm using) for about 10-20 thousand requests, but I think this memory problem is giving me trouble after that. I thought it was a connections problem (I was getting connection errors from the tool), then I thought I had screwed something up in my code (and I've tried different versions, nothing seems to affect performance), then I noticed the memory never went above ~154 MB, so now I'm examining memory issues. My problem is still the same, after so many requests (and thus some amount of information stored in memory), Tomcat starts to use up a whole lot of CPU time. I think I hit the memory limit (as I get out of memory errors), so I'm trying to increase the memory Tomcat has, without much luck. I set the environment variable (as I mentioned before), but it does not appear to be working.

RE: Checking Tomcat's Memory
Alright, new environment variable... CATALINA_OPTS=-server -Xms1024m -Xmx3072m Should give me a range of 1-3 gigs. When I restart Tomcat, however, this doesn't appear to affect anything. I'm running a simple memory servlet, as suggested by Yoav Shapira, to simply create a whole bunch of memory, but it still caps out as if it were using the defaults. Couple questions: 1) Must I restart the machine for the CATALINA_OPTS to take effect (or, what is wrong with my environment variable)? In my experience this has not been necessary, only restart the application/process. (Maybe this is a WinNT4 quirk or something similar). 2) Tomcat's configuration files most likely support what I'm trying to do. Is there an appropriate/recommended place I define this envirnoment variable? Quick config rundown: JDK 1.4, WinNT4 (or 2K), Tomcat 4.0.4.

RE: Checking Tomcat's Memory
Hi, On unix, we put our CATALINA_OPTS settings in $CATALINA_HOME/bin/catalina.sh. Are you running tomcat as a service on NT or from the command line? If you're running from the command line, can you do echo %CATALINA_OPTS% before starting tomcat and verify the values are set correctly? Regardless of the above, I would try putting CATALINA_OPTS in catalina.bat. Can't hurt ;) Yoav Shapira Millennium ChemInformatics -Original Message- From: Marinko, Jeff [mailto:[EMAIL PROTECTED]] Sent: Thursday, August 15, 2002 2:49 PM To: 'Tomcat Users List' Subject: RE: Checking Tomcat's Memory Alright, new environment variable...

OutOfMemory Error
Hi, outofmemory problem crashes my Standalone Tomcat Server(NT 4, Tomcat 4.03). large images on the site. From reading on subject, seems I have to increase the JVM heap size. Question? I created a jsp page that shows me the Total memory and Free memory on the site. The free memory balances between a number and another getting smaller and smaller until it crashes. If I add memory, does that only mean its going to take longer before it crashes? Question? writing JAVA -Xms128m get Incompatible initial and maximum heap size Please help Pat
RE: OutOfMemory Error
To answer your first question, I'm assuming you only have so much memory, so if you keep allocating memory, you'll eventually run out and then you'll have problems. As long as the JVM can reclaim memory, you should be alright. For your second question, it should look something like this: JAVA -Xms128m -Xmx256m Where -Xmx256m is your maximum heap size. It gave you that error because the default is 80 megs (which I'm having trouble with), so setting the minimum above 80 megs gives you the error message. http://java.sun.com/j2se/1.4/docs/tooldocs/windows/java.html For the windows standard and non-standard options (such as -Xms and -Xmx). Hope that clears it up for you. -Original Message- From: Patrick Codere [mailto:[EMAIL PROTECTED]] Sent: Thursday, August 15, 2002 1:10 PM To: 'Tomcat Users List' Subject: OutOfMemory Error Hi, outofmemory problem crashes my Standalone Tomcat Server(NT 4, Tomcat 4.03). large images on the site.

RE: OutOfMemory Error
Thanks a lot, Still, I really feel stupid here, but I tried java -Xms128m -Xmx256m on the command prompt and get the Usage: java [-options] list Thanks -Original Message- From: Marinko, Jeff [mailto:[EMAIL PROTECTED]] Sent: Thursday, August 15, 2002 4:07 PM To: 'Tomcat Users List' Subject: RE: OutOfMemory Error To answer your first question, I'm assuming you only have so much memory, so if you keep allocating memory, you'll eventually run out and then you'll have problems.
