Tomcat JNDI custom resource factory questions
Hi! I am using Tomcat 7.0.29 with a custom JNDI resource factory (http://tomcat.apache.org/tomcat-7.0-doc/jndi-resources-howto.html#Adding_Custom_Resource_Factories). The factory creates a connection to data server which then can be shared between servlets. Two questions regarding the resource usage. 1. Creation of the resource factory, isn't is supposed to be thread-safe? The resource (connection) is used by two servlets which obtains it on start-up. It works fine if the servlets are loaded one after another - the first servlet asks JNDI for a connection, JNDI creates a factory, the factory creates a connection, JNDI gives the connection to the servlet; the second one ask JNDI for a connection and immediately gets the same connection, without calling the factory. But if the servlets are being started exactly at the same time, they get two different connections created by two different factories. Shouldn't the factory singleton-ness be managed by Tomcat? 2. What is the correct way to close the resource? How should I close the resource if the webapp is being stopped/undeployed? My factory creates a connection on "please create a resource" call somewhere from inside JNDI, lets the connection go and doesn't know how many servlets use it. Users of the resource are independent, they do not know how many of them are and do not know when the resource can be closed. So I would expect some kind of "it's time to close the resource(s)" call from JNDI. Is there one? I know that I can track all the resources creation in a ServletContextListener and then close them in contextDestroyed(), but I hope there is a nicer way.

Re: HTTP NIO connector not supporting IPv6
Thanks Dan, Jeff. There are no errors in catalina.log file. The connector tags are defined as below in server.xml. This configuration does not support IPv6. Below configuration supports IPv6. The only difference is the protocol. Please let me know if something missing here?

1. You can add whitespace around ',' and '=' for better readability.
(I do not remember whether 7.0.27 allows it, but 7.0.30 should allow
whitespace there).
2. It is possible to define a system property (via -D in the options
list at startup, or via catalina.properties file) and reference it as
${propname}.
3. Having 200 aliases means that Tomcat would have to try 200
different prefixes for each resource lookup. Maybe it would not be
noticeable (compared to the other time spent in delivering a
response), but it still seems like a waste of time.

RE: IIS 7.5 + AJP Connector
okay.. worked it out. Seems like I had the application pool set to no .net framework... and integrated pipeline NOT classic. But it seem if you don't set a .net it uses the old IIS6 ISAPI reg settings ! So now I have set .net framework to 4 , even though the plugin doesn't use it (I presume) and the thread count is over the 264. oh yeah. the pain of using IIS !

tomcat7-maven-plugin 2.0-SNAPSHOT:deploy ignores server configuration
Hi, If this is not the correct list to ask about the Tomcat Maven plugins then I apologize in advance. I have been googiling for better places, but to no avail. I have a Maven Web application project and am trying to deploy to a local Tomcat 7 server on http://localhost:8080. I can access this server with my browser and deploy the web app manually. I also set the correct credentials in the maven settings.xml configuration file. I follow the documentation about the tomcat7:deploy goal: http://tomcat.apache.org/maven-plugin-2.0-SNAPSHOT/tomcat7-maven-plugin/deploy-mojo.html Although the server is running on the plugin's default URL I get a 403 HTTP error. I have tried to add the ".text" using the parameter, but this is completely ignored (I can see in the plugin output that it always uses the default URL) I also set the parameter to match the id in mavens settings.xml but the behavior does not change. It seems that tomcat7-maven-plugin 2.0-SNAPSHOT ignores its parameters. Or am I doing something wrong?

RE: HTTP NIO connector not supporting IPv6
Aditi - All connectors support both IPv4 and IPv6, including BIO, NIO, and native/APR. However, how you configure the connector will affect which protocol is supported. As far as I've been able to tell from empirical testing (see previous threads), if you leave off the address parameter, the java-based connectors (BIO & NIO) will set up listeners on both of the "any" addresses, i.e. 0.0.0.0:port for IPv4 and [::]:port for IPv6. Unless it's been fixed in a recent release, the APR will only set up to listen on the IPv6 address. You have to specifically give it the IPv4 "any" if you want IPv4 support. Since I only support IPv4 right now, I haven't re-tested the current version of APR. (pltr) So, as Daniel says, please resend your message with copies of the actual tags, minus any passwords and excess comments. If you are seeing any errors in your catalina.log file, those would be helpful as well.

Logging the effective web.xml is performed in o.a.c.startup.ContextConfig. Search for org.apache.tomcat.util.scan.Constants.MERGED_WEB_XML 2. I would like to remove this MERGED_WEB_XML from future versions. Instead of re-parsing web.xml Jasper would better be using Servlet API to query needed features. IIRC, actually Jasper does not need much: just specification version and jsp-config. A downside is that Jasper has to be used stand-alone as JspC. So it should still be able to parse web.xml. So either a) refactor the whole parsing of web.xml, moving it into reusable component (like Mark wrote), or b) keep the current parsing code in Jasper and make its own objects implement relevant parts of Servlet API. This is filed as BZ53737. The first attempt was in r1377511 (+discussion), reverted in r1377539. https://issues.apache.org/bugzilla/show_bug.cgi?id=53737 http://markmail.org/message/dyuyuuglunuy4qej http://markmail.org/message/kknk2xh7wdcznsv7 3. Note, that currently this "merged web xml" may miss some features. - It may change the order of elements vs. original web.xml. There are a number of elements whose order is not important. Tomcat uses HashMap for those, so their order may change randomly from run to run. - It may miss some elements from original web.xml, that are not parsed by Tomcat. Such as s. Several weeks ago I went through the code, correcting some typos in element names and wrong order of elements.

Wdyt? There is going to need to be a lot of refactoring for this. I'm not sure if a patch is the right way to go. Neither am I sure what the best way is. Maybe a git branch (e.g. on github) with a series of patches? I don't have enough experience with the git-svn integration to know if that would be easier or harder to deal with. In terms of what needs to be done: - the end result needs to be useable by both Jasper and Catalina - that pretty much means a new package and JAR under o.a.tomcat - Jasper cannot depend on Catalina (hence why everything needs to move packages) - the things that need to move to this new package - the web.xml parsing (i.e.the digester) - the annotation scanning - the SCI scanning - the merging - the object representation of web.xml - switch everything over to the new implementation This is a big change but most of it is just moving stuff around. It isn't changing functionality (well it is - JspC would process fragments which it doesn't currently for example but all the functional changes would be improvements of this nature) I suggest making a proposal to the dev list. If that gets support, I'd be happy to help with this. I suspect in that case a series of svn moves and patches would follow.

HTTP NIO connector not supporting IPv6
Hi, We have a web server hosted on Apache Tomcat Version 7.0.22. Machine details: Windows 2008 server machine, 32-bit OS Java version: jdk1.6.0_25 Two HTTP connectors are defined in server.xml. 1. For non-SSL requests: Connector with protocol="HTTP/1.1" (HTTP BIO connector) 2. For SSL requests: Connector with protocol="org.apache.coyote.http11.Http11NioProtocol" (HTTP NIO connector) With the above configuration server is not accessible through the IPv6 address. The “netstat –an” command also does not list the connector ports(defined in server.xml). *On modifying these two connectors to use the BIO implementation, protocol=“org.apache.coyote.http11.Http11Protocol” the server supports IPv6. * Any idea why HTTP NIO connector would not support IPv6? Thanks & Regards, Aditi

It would be very useful if I can provide this as part of the build infrastructure for example. If you can give me a hint from where to start I may try to provide a patch for 8.0.x?

I haven't got much further than "it would be useful if..." so it may turn out to be impractical.
