java heap space error
Hi all, I have a java web application running on tomcat and I get java heap space not enough error temporarily. Each time I am increasing the JMV heap option by modifying the system variable CATALINA_OPTS. However, this solves the problem temporarily. I get the same error when I work for some more weeks on the development of the application. Can anybody help me solve the problem? Thanks in advance.

John Smith schrieb: Is it possible by using tomcat 6.0.20 with different instances with diff ips but same port no 80 on one system ??? Only one process can bind to any given IP/port combination. I ran instance a on port 80 (it ran), but when I tried to run another instance b on port 80 ( I got java.net.BindException: Address already in use Because that port is already taken for the IP number in question. My question is I need to run three applications on port 80 on same machine but different IPs, what is the best way and how ? Mark provided a link on how to configure different connectors. I made an effort of grokking all this server.xml configuration and have come up with two questions of my own. Please read on. You can use the following XSLT to strip your server.xml of all the helpful comments so you see that it's less frightening than it appears. xsl:stylesheet version=1.0 xmlns:xsl=http://www.w3.org/1999/XSL/Transform; xsl:strip-space elements=*/!-- tabula rasa in -- xsl:output indent=yes/!-- tabula rasa out -- xsl:template match=comment()/!-- weed comments -- xsl:template match=@*|node()!-- identity template -- xsl:copyxsl:apply-templates select=@*|node()//xsl:copy /xsl:template /xsl:stylesheet So you have a Server [1]. It has a couple of Listener elements and GlobalNamingResources. A server may have mulitple Service elements. Don't ask me why you'd want more than one Service elements [2] - because that's what I'd like to ask the experts. Anyone? Anyway, as you can see from [2], a Service represents the combination of one or more Connector components that share a single Engine component for processing incoming requests. Define all the connectors [3] you want for your different IP numbers and ports. They'll all be processed by the single Engine [4], which supports virtual hosting and dispatches incoming requests (based on the HTTP Host header) to a matching virtual host, or, failing that, the default host, which is mandatory both as Engine/@defaultHost and Engine/Host/@name. As a configuration artefact, the Host [5] is decoupled from the IP numbers and only associated with DNS names or aliases. IP numbers and ports are the job of the Connector. Now you could nest Context elements defining your applications inside Host elements - but in Tomcat 6 this is not recommended. Now each Host has its place where to look for applications, which is configured in Host/@appBase. That's where you put your WAR files. Here's my second question: Say I have various Connector bindings set up receiving requests and dispatching them to my single Engine, which has three hosts alpha, beta and gamma. What would be the best way to associate my shiny new second-world.war with all of alpha, beta and gamma? (1) By dropping a copy in each of the different Host/@appBase? (2) By having all three Host/@appBase point to the same location (and then of course put the WAR there)?

Basically: check and re-check all your Resource parameters, make sure your datasource name is consistent, and only put your MySQL driver JAR file in one place: in the server's library directory (common/lib on TC 4.1 IIRC). I post the datasource configuration in the server.xml again: Context docBase=myApp path=/myApp reloadable=true debug=1 Logger className=org.apache.catalina.logger.FileLogger prefix=procurement_log. suffix=.txt timestamp=true/ It wouldn't hurt to turn up debug to something like 99.

I suspect that it should be com.ibm.db2.jabc.app.DB2Driver instead of that you have. Case does matter. Also, is the URL you have above the correct URL for DB2? Does anything need to be set up in a separate file to resolve oscahe (and is that spelled right? oscache, maybe?)? I remember Oracle's non-type-IV JDBC drivers needed a separate file to configure the driver. The last thing I'd ask about your webapp is what the code looks like that is trying to grab a connection from the connection pool. Is it your own code? If so, post that. If you are using something like Hibernate, an O-R mapper, or some other DB framework, post the configuration for /that/ so we can see what the expected DataSource JNDI name is. Finally, I wonder if upgrading to a newer level of Tomcat is an option. I see it's a legacy application, but the servlet API hasn't changed that dramatically over the years (other than adding features and tightening-down the specification of older ones).

Don't ask me why you'd want more than one Service elements [2] - because that's what I'd like to ask the experts. Anyone? Seemed like a good idea at the time? If you look inside Tomcat, you'll see that it's a set of nested containers, with Server being the top one, and Service the next layer. You might want to use multiple Service elements if you want to run a single JVM with independent servlet engines inside (think embedded controller, where the number of processes is limited).

(2) By having all three Host/@appBase point to the same location (and then of course put the WAR there)? This appears to work, but each Host will be monitoring the same locations for changes (assuming autoDeploy is true), and there might be some timing issues. (3) By some other means? By placing a second_world.xml file in each of the conf/Catalina/[host] directories, with the Context element therein having a docBase attribute pointing to the actual location of the .war file. This is pretty much equivalent to #2, except you can tailor the Context element for each Host, if needed. Regardless, your webapp will be deployed once for each Host. If you don't want that, just use a single Host, and let it field requests for all of alpha, beta, and gamma. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Caldarale, Charles R schrieb: From: Michael Ludwig [mailto:m...@as-guides.com] A server may have mulitple Service elements. Don't ask me why you'd want more than one Service elements [2] - because that's what I'd like to ask the experts. Anyone? Seemed like a good idea at the time? If you look inside Tomcat, you'll see that it's a set of nested containers, with Server being the top one, and Service the next layer. You might want to use multiple Service elements if you want to run a single JVM with independent servlet engines inside (think embedded controller, where the number of processes is limited). Thanks, that sufficiently clarifies it. (3) By some other means? By placing a second_world.xml file in each of the conf/Catalina/[host] directories, with the Context element therein having a docBase attribute pointing to the actual location of the .war file. This is pretty much equivalent to #2, except you can tailor the Context element for each Host, if needed. A detail that adds flexibility and makes a difference. In practice, I would probably deploy the app, grab the extracted second_world.xml, put it under version control (I know admins don't use that, but I would), make my changes, commit them, and then place a copy in each of the aforementioned directories so it prevents the original from the WAR to be extracted and used. Does that sound like solid operating procedure? :-) Regardless, your webapp will be deployed once for each Host. If you don't want that, just use a single Host, and let it field requests for all of alpha, beta, and gamma. Just to be sure, would I do that by using: Home name=alpha ...

What is your appBase for your Host in server.xml? Please re-post the Context definition that does work, and the one that does not work (no need to re-post the Resource within the Context). I am rechecking and rechecking [the JNDI configuration]. I found in common/lib directory there are one db2java.jar and one COM folder, basically it is the unzipped version of that db2java.jar. Not sure why the COM folder is there. But I try to remove the COM folder, the error is still there. The COM folder will be igonred; only .jar files will be used from within that directory. Forget about the database driver: I think that was a distraction from the real error (shown above). Yes, IBM driver really starts with COM all in caps. Ok. I just so confused why I set docBase as local, Tomcat is working? Can you explain further what you mean when you say set docBase as local versus whatever else you set it to?

My colleague told me we have to use Tomcat 4, as Tomcat 5 requires JDK 1.5. Is that true? As Chuck says, Tomcat 5.5 can run on JDK 1.4 if you install the compatibility package (which is easy). I am more than happy to switch to higher version of Tomcat. Basically I only use Tomcat on local for development, and we are using Websphere application server in production. That raises a few other questions: 1. If this is a legacy application, how much development is really occurring? 2. Why not run the same environment in both dev and prod? 3. Why can't you run under JDK 1.5 or 1.6?

There's a digester rule defined for it, but that's it. So even if you make a typo in any of the data provided in the resource-ref element, Tomcat won't warn you about it. Maybe the documentation should very clearly state this, i.e. Note: the resource-ref element is totally ignored by Tomcat. You can provide this element to be compatible with other servlet containers that adhere strictly to the Servlet spec(*) Also note that because Tomcat totally and utterly ignores the element, any faulty data provided by you won't be detected by Tomcat.

Using multiple DataSource's for fail-over.
Tomcat 6.0.20 using DBCP DataSource Java 1.6.0_16 Oracle 10g with RAC. I've got two Oracle RAC nodes, mirroring each other. My current fail-over method if the primary node fails is to shut down the web servers, reconfigure them to use the secondary node and restart the web servers. Not pleasant. I'm thinking I can make a FailOverDataSource that implements DataSource and wraps around DataSource's for each of the two nodes. Its getConnection() method would try to use the getConnection() from the primary node, and if that fails, it would try the secondary node. Repeat logic for other DataSource methods. Instant automagic fail-over. I've actually written it, and it seems to get a hold of both DataSource's fine. I can't kill the primary on an active busy system to do a real test though. I'm thinking I can't be the first person to think of this. Are there any obvious problems with this idea? - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Hi Chuck, Good to know that. I will definitely try the Tomcat 5 with JDK 1.4. Thanks, Jamez.

How do I remove 'S' from HTTPS - JAAS configured on tomcat, JSF webapp
How do I remove HTTPS after login in ? I have read other posts. I still need this thread as it has to do with JAAS on tomcat. Please read on. For the hasty, jump to 9 onwards. My UI stack is as follows : * JSF 1.2, Facelets, Richfaces 3.2.1 * JAAS * Tomcat 6 0. Relevant web.xml entries security-constraint display-nameUser Login Page/display-name web-resource-collection web-resource-nameLogin Resource/web-resource-name url-pattern/pages/secure/*/url-pattern http-methodGET/http-method http-methodPOST/http-method /web-resource-collection auth-constraint role-nameUser/role-name /auth-constraint user-data-constraint transport-guaranteeCONFIDENTIAL/transport-guarantee /user-data-constraint /security-constraint ... ... login-config auth-methodFORM/auth-method realm-nameprojx/realm-name form-login-config form-login-page/pages/login/login.jsf/form-login-page form-error-page/pages/login/loginerror.jsf/form-error-page /form-login-config /login-config 0.1 Login page : rich:panel id=loginPanel f:facet name=headerLogin Panel/f:facet f:verbatim form method=post action=j_security_check tabletr tdUser Id/td tdinput type=text name=j_username //td /tr tr tdPassword/td tdinput type=password name=j_password //td /tr tr td align=center input type=submit value=Login / /td /tr/table /form /f:verbatim /rich:panel 1. SSL Enabled Login page 2. Rest are non SSL-pages 3. JAAS Configured with some page requiring login (therefore fwd to SSL) 4. Homepage has 'Login' hyperlink -- which points to --/pages/secure/Userhomepage.jsf Simple Login Usercase 5. User clicks on 'Login' hyperlink 6. Tomcat CMA intercepts and takes user to /pages/login/login.jsf but URL shows https://localhost:8443/abc/pages/secure/Userhomepage.jsf 7. User keys in credentials and login is successful 8. Userhomepage.jsf http response is generated and shown on browser BUT URL is still https://localhost:8443/abc/pages/secure/Userhomepage.jsf Problem - 9. HTTPS should not be show from 8 onwards. How do I remove it ? Questions 10. I know that HTTPS has to be programattically removed. But between 7 and 8, How do I do it ? a) Where do I put a URL rewrite filter code ? It won't even be invoked.. b) How can I do it programmatically when the redirection is being done by Tomcat ? On a side note (question on JAAS configured on Tomcat ) --- 11. Why do I have to declare '/pages/secure/*' with auth-constraint role-nameUser/role-name /auth-constraint ? 12. Why isn't there a way to just forward to login.jsf which forwards to j_security_check ? 13. Is there a way to make Tomcat container aware of a JAASubject What I would really like is a Richfaces modal panel for a login ? Such a simple use case has become really complicated. Instead of flexibility, across presentation layers, it's ties you down to a one mechanism. Very frustrating.

Re: tomcat 4.1.31 problem
Hi Chris, Thanks for your patience with me. :-) What is your appBase for your Host in server.xml? Please re-post the Context definition that does work, and the one that does not work (no need to re-post the Resource within the Context). 1. appBase Host appBase=webapps autoDeploy=true debug=0 name=localhost unpackWARs=true 2. working Context--- Context docBase=* C:\\ProcurementProject\\WebContent* path=/procurement reloadable=true debug=1 *C:\\ProcurementProject\\WebContent *is where my application (source code etc.) located. 3. not-working Context--- Context docBase=*procurement* path=/procurement reloadable=true debug=1 *procurement* is the War file I deployed to webapps under Tomcat. This is the only difference I have for the working and not-working context configuration. The rest of context configuration is the same. 1. If this is a legacy application, how much development is really occurring? Not much development to do. Just some minor changes need to be implemented. Why not run the same environment in both dev and prod? I guess we don't have Windows version of WAS server. Not really sure. Maybe Tomcat is faster? Why can't you run under JDK 1.5 or 1.6? Why not Tomcat 6.0? This project was developed since 2002 and has a lot obsolete methods even under JDK 1.4. It won't be able to compile under higer version of JDK. Thanks, Jamez.
Re: AJP connections just stop working
Hi,
How did the results of your monitoring go ? Were you connection/keepalive
timeouts helping ? Are they still set at 10mins ?
Please outline the steps you made if the problem has indeed been resolved.
Thanks

Here are my updates :
Interesting finding is whatever AJP connectors stuck in Keepalive mode for
long time are for requests coming from remote clients. All connections for
requests coming from local (internal network) clients were changed to
CLOSE_WAIT after some time.
Today I tried with keepAliveTimeout and connectionTimeout setting at
server.xml
Connector port=8009 address=${jboss.bind.address} protocol=AJP/1.3
emptySessionPath=true enableLookups=false redirectPort=8443
connectionTimeout=30 keepAliveTimeout=30 /
I monitored from both JBoss JMX console and netstat. Connectors at JMX
console stayed at stage 6 (STAGE_KEEPALIVE) for 5 minutes and changed to
stage 7 (STAGE_ENDED ) after keep alive timeout (5 minutes). But in
netstat it is still shown up as follows:
netstat -aonp | grep 8009
tcp0 0 0.0.0.0:8009 0.0.0.0:*
LISTEN 5229/java off (0.00/0/0)

tcp0 0 xx.xx.xx.xxx:8009yy.yy.yyy.yyy:49765
ESTABLISHED 25229/java off (0.00/0/0)
pid 25229 is process id of JBoss. I am running JBoss on CentOS 5.2, Kernel
2.6.18-.
I will be monitoring the outcomes tonight.

Hello,
We are also haveing exact same issue in our environment. We are using
JBoss 4.2.3, Apache 2.2.11 with mod_proxy_ajp using ajp to connect
between Apache and JBoss. It happens intermittently and when i happnes
all AJP's TCP connections are stayed in ESTABLISHED state on JBoss
machine. In thread dump, all AJP threads are in waiting state.
Anyone found solution or work around for this issue?
Thanks,
GC
For now I have set the connectionTimeout to 10 minutes on my AJP
connection, e.g.
!-- Define an AJP 1.3 Connector on port 8009, timeout in 10 mins.
--
Connector port=8009 address=${jboss.bind.address}
protocol=AJP/1.3
emptySessionPath=true enableLookups=false
redirectPort=8443
connectionTimeout=60
/
I am monitoring results, it is too soon to tell if this alone will solve
the problem or if I also have to delve into my firewall (I was incorrect
in my original response above - there IS a firewall between my IIS proxy
and my JBoss server, and it has a 1 hour idle tcp session timeout), or my
IIS proxy (which is configured with a 5-minute socket timeout).

Re: Unable to access files outside Webapp directory in tomcat
Hi, I have my Web application installed in C:\Tomcat\webapp\ROOT. Now, through the Web page of this application, the user uploads an image which the application saves in C:\files folder using ImageIO class of JAVA. Now as soon as the file is uploaded, there should be a download button enabled for this uploaded image. If the user hits download, he should be able to download the file he uploaded. I'm done with saving the file to C:\files but I don't know how to make it downloadable when the download button is clicked because the files folder is outside the webapp directory. I hope this explains my issue. Thanks Akash.
