Error re-starting war application
Hi list I've posted that question already before. I am using Eclipse WTP for development of a web application and use it's 'Export' function for creating the .war file. Installing that application on Tomcat 5.5.x works fine. But, stopping and re-starting the application fails every time with a NullPointerException. Do you have any hints? Thanks

Re: Tomcat as a standalone webserver. Why not?
This issue is discussed endlessly as far as I can see, both camps argue very well for their case However, my take from personal experience is that its very handy to have Apache in front, because it gives you a lot of scope to do little fixes and tweaks to odd users causing problems without any service downtime. For example you can pretty much add Apache Rewrite rules all over the shop to fix up little issues without having to actually restart any servers, (just an Apache SIGHUP, or reload). You can also fiddle with the various request headers, response headers, logging of request, response headers, with no impact on the back-end tomcat layer and its webapps. Of course there is the load balancer issue as well, if you require/desire to have sticky sessions. Obviously if your code is perfect and bug free and users are all perfect, and sticky sessions are not required then then perhaps tomcat-only is the solution. Although I've yet to meet an author of bug free code. Thats my opinion anyway. Mark On Thu, 2006-06-01 at 12:05 +0200, Danny Lee wrote: Hi guys!

Subject: Redeploying a war file from a build script
I am writing a build script that would redeploy a war file at the end of
the build.
If I use DeployTask and the application was already deployed from a
previous build, I get an error.
If I use UndeployTask first and the application is not already deployed
(which would happen the first time somebody runs the script on their
machine or if there's a failure between calls to UndeployTask and
DeployTask), I get an error.
I would like the script to be robust enough that it doesn't require the
user to do more than install Tomcat (and my distro, natch) on their
machine.
I thought ListTask useful, here, but I've read through the docs and
could not figure out how to capture the output for parsing (so I could
check whether this particular application is already deployed).
Any thoughts would be helpful,
Bill

Re: Tomcat as a standalone webserver. Why not?
As it happens I can't really begin to count the number of times we've applied hacks at the Apache level to work around code bugs (did I say bug? I meant feature...). Although to be fair most of these are caused by users/customers doing odd things outside the spec of the current code. We also deal heavily with accesses from mobile phones, each one of which has new and interesting features in its web browser, some of which just can't be easily dealt with without direct control over the request/response headers which Apache makes easy. But more generally another big win we have found is the ability to fairly easily have Apache catch certain requests (ie for specific users) and hand them off to development/staging systems rather than the production systems. This is used quite often in our test/release cycle, and avoids having to have the production system tomcat layer even know that such hacky stuff is going on, whilst outside users can't necessarily know which back-end system they are using.

The java heap works differently from the C heap, and native instructions at runtime are organized differently.

Re: Tomcat as a standalone webserver. Why not?
If you are running a big site with multiple servers, you do NOT want to run Apache in front of your Tomcats - All that you do is increase latency, and half your performance. The HTTP connector in TC 5.x is more than adequate to deal with heavy traffic loads. To be honest, I try not to use Apache at all any more, and tend towards lighttpd - depending of course on the requirements. We deliver our images via a separate url ie: img.domain.com and www.domain.com. We have the images delivered via a lighttpd, and our dynamic content delivered via tomcat - we currently do our load balacing with an F5 BigIP for these two fully qualified host names. Yes - you can do all sorts of snazzy things with a proxy (like apache and mod_proxy/ mod_jk) out front - but I do not think it is worth the cost of the performance that is lost... We did some tests 2 years ago for our system and discovered, with Apache and TC running on the same machine With mod_jk, apache 2.0 and TC 5.0 50 requests/ sec With just TC5.0 100 request/ sec ... As for security - you have TC running in both cases - mod_jk passes the requests unfiltered straight through Therefore by adding Apache, you are only adding something else to go wrong - be broken - not solving any problems...

Embedded Tomcat does not read META-INF/context.xml?
I'm running Tomcat 5.5.7 in embedded mode, i.e., starting Tomcat using
the org.apache.catalina.startup.Embedded class. For some reason, the
JNDI resource I configured in
$tomcat_home/webapps/my_webapp/META-INF/context.xml is not created
when Tomcat starts. Your help will be greatly appreciated!!
The following is the code that I use for starting Tomcat:
Embedded tomcat = new Embedded();
// create an Engine
Engine catalina = tomcat.createEngine();
catalina.setName(Catalina);
catalina.setDefaultHost(localhost);
// create Host
StandardHost localhost = (StandardHost)
tomcat.createHost(localhost, webapps);
// add host to Engine
catalina.addChild(localhost);
// create application Context
StandardContext appCtx = (StandardContext)
tomcat.createContext(/gc, gc);
// make the web app's class loader use the normal delegation
model to search for classes
appCtx.setDelegate(true);
// add context to host
localhost.addChild(appCtx);
// add new Engine to set of Engine for embedded server
tomcat.addEngine(catalina);
// create HTTP Connector
Connector httpConnector =
tomcat.createConnector((java.net.InetAddress)null, 8080, false);
IntrospectionUtils.setProperty(httpConnector, redirectPort, 8443);
// add new Connector to set of Connectors for embedded server,
associated with Engine
tomcat.addConnector(httpConnector);
// create HTTPS Connector
Connector httpsConnector =
tomcat.createConnector((java.net.InetAddress)null, 8443, true);
httpsConnector.setScheme(https);
IntrospectionUtils.setProperty(httpsConnector, sslProtocol, TLS);
IntrospectionUtils.setProperty(httpsConnector, keypass, changeit);
IntrospectionUtils.setProperty(httpsConnector, keystore,
emf.keystore);
// add new Connector to set of Connectors for embedded server,

tomcat.addConnector(httpsConnector);
// start operation
try {
tomcat.start();
} catch (org.apache.catalina.LifecycleException ex) {
ex.printStackTrace();
}
As you can see from the code, we have one web app called gc running
inside Tomcat. Under the $tomcat_home/webapps/gc directory, we have a
META-INF/context.xml file that defines one JNDI resource (a
javax.sql.DataSource object):
Context docBase=gc
path=/gc
crossContext=true reloadable=true debug=1
workDir=work/Catalina/localhost/gc
Resource
name=jdbc/gc
auth=Container
description=GC DataSource Reference
type=javax.sql.DataSource
factory=com.good.gc.common.util.GCTomcatDataSourceFactory
driverClassName=org.postgresql.Driver
url=jdbc:postgresql://localhost:5432/gc
username=postgres
maxIdle=2
maxWait=-1
maxActive=4
validationQuery=select now()
/
/Context
We use the Spring Framework (version 1.2.3 I believe) for the gc
webapp, and inside the spring context config file, we try to grab the
DataSource from the java:comp/env context this way:
bean id=myDataSource
class=org.springframework.jndi.JndiObjectFactoryBean
property name=jndiName
valuejava:/comp/env/jdbc/gc/value
/property
/bean
Everything used to work just fine when we used Tomcat in standalone
mode. But now that we switched to embedded mode, we got the following

Re: Webapp reload failing, but restarting tomcat allows webapp to load fine
On reading more in the release notes (http://tomcat.apache.org/tomcat-5.5-doc/RELEASE-NOTES.txt), I figured I'd give the shared/lib idea a try. I found that just by moving the BouncyCastle JCE jar into shared/lib and out of the WEB-INF/lib of the various webapps, all seems to work okay. On another note, I tried moving log4j's JAR into shared/lib, but it didn't seem to work. Even though each webapp has its own log4j.properties file in the WEB-INF/classes, with each pointing to a distinct log, when the log4j jar was put in shared/lib, all of the output from all of the webapps went into the same file. So it seems to have some static initializations too that introduce this oddity. David David Wall wrote: Martin, Thanks for your suggestion, but it's unlikely that web.xml was misconfigured just because of this TC upgrade (it wouldn't have needed to change). Also, when I restart tomcat (rather than just reload via the manager), the webapp comes up just fine. It's only on a reload that things fail, and they didn't even fail under 5.5.12, but do under 5.5.17. It seems very likely this is related to a TC bug when contexts are being reloaded with some classpath-related issue remaining. I know that such classpath issues can be tricky when the webapp has to be dropped from the running JVM and then later added back in. David Martin Gainty wrote: If you check the logs ..more than likely you may be trying to pull a class that is not on classpath or maybe an aberrant configuration abeerant config is servlet-mapping may be munged in web.xml HTH, Martin -- - Original Message - It seems there's something that's gone wrong between TC 5.5.12 and TC 5.5.17 as it relates to reloading webapps through the Manager app. I upgraded to get the fix related to webapp reloads for listeners, and that seemed to work (on restart with a new web.xml, it didn't call the listeners from the previous web.xml anymore). But I now get an odd error on restart related to decryption via JCE. I've not been able to track down why this is occuring, but it seems to be related to some sort of context/classpath issue on the reload. This can be seen in that when I start tomcat, all of my webapps load fine. If I click to reload a webapp via the Manager, that webapp will fail. If I then restart tomcat, that webapp loads fine again. Is this a known issue? It may be related to other issues I've run into with respect to JCE providers on reloads that did not occur in 5.5.12.

Re: NetBeans 5.0 and Tomcat 5.5.16 ... Please Help
You can use eclipse with Exadelstudio plugin, which is freely available. The newest version is 3.2, I think. The problem may be u may not compiled the project correctly and deployed. And here u r not specyfying anything like the mechanism u r using, to connect 2 the remote server.I assume u r uisng jdbc.

JNDI Datasource in embedded 5.0.28 ?
Does anyone know how to configure JNDI Datasource in 5.0.28 Google GWT uses embedded 5.0.28 in hosted and nobody seems to know how to configure a datasource on the GWT list. It would be greatly appreciated if anyone could show me how to configure this. (GWT is basically useless to me without a connection to my DB -- can't believe the guys at google don't have docs on this themselves...) -jm

Vijaya One, your question is terribly vague. I get a 404 when accessing the remote sql server? Are you trying to connect to a JSP page under your Tomcat? Are you running the web application in Netbeans? Did NB launch your external browser and point you to the running Tomcat instance address and port? Are you running a different version of Tomcat then the one that shipped with it? Are you actually running it in Netbeans? Have you ever used JDBC and jTDS together and that is working fine? Have you gotten it working in other web applications period? I'm on both this list and the NB list. You can ask your question there, but if it comes down to something with your configuration and Tomcat you might be directed back here. Ask on [EMAIL PROTECTED] (you'll need to sign up for the list). You'll need to provide some common sense basics though to help someone help you.

Re: NetBeans 5.0 and Tomcat 5.5.16 ... Please Help
There are just too many things involved here. A better approach would be to get the pieces working separately. step by step 1) connect to DB using a stand-alone program 2) connect to some example servlet in tomcat 3) now use tomcat bundled with netbeans 4) Then only attempt to put all the pieces together.
