Apache Tomcat7 service start randomly after the installation of McAfee antivirus.
Good morning, We have 4 identical servers with a scheduled task running every night on each of them. This task Stop Tomcat - Update some data - Start Tomcat. This worked fine for months. We have installed a new antivirus McAfee 3 weeks ago. Now the Tomcat7 service starts randomly. At least 1 of the 4 server needs a manual start of the Tomcat7 service every morning. Do you know if there is specifics problems between Tomcat and Mc Afee ? We have already tried to exclude Tomcat.exe from McAfee scanning. Is there other thing we could exclude without compromising the security ?

It works fine locally but I want to deploy it using Elastic Beanstalk within Amazon Webservices but for it to work I need the data files within the war, then I can allow EB to create new instances when load balancing/scaling and it will work because the data fields are included in the war at deployment time. I have checked that EB does unjar the war so that when my code comes to use the files they will be real files not still contained within the War. With that in mind where could i put the data files so they not considered by tomcat as java classes , and supplementary question how do I modify my pom file to do this with maven What? Java won't try to load random files as .class files. I tried putting the files into the resources directory of my maven project, when I deployed the resulting war it would start (did previously) and opening the war found the files were added under WEB-INF/classes, that is what I meant. So I need to put them somewhere else. It sounds like you're not building these within the deployed application, but adding them at build time. Why can't your application read the files from WEB-INF/classes with getResourceAsStream? I think the issue is that Lucene reads a bunch of files to manage its index, and there is not (currently) an implementation that can ready them out of a ZIP archive. So I think Paul needs to expand the assets to the disk and then use the Lucene classes that do understand the disk. I know you can use a RDBMS to back a Lucene index, so I'm surprised there isn't anything (that I could see on my quick review) to support loading from a ZIP resource. -chris I guess I'm a little confused as to what this means. I have a simple WAR based web application that uses Lucene created indexes to provide search results in a xml format. Especially given the following context: and supplementary question how do I modify my pom file to do this with maven I was under the impression that Paul was building a separate application using Lucene during the build stage to create the indexes, but then using an application - specific mechanism to use those indexes. That's what I thought, too. If Paul is using Lucene API (Document, DirectoryReader, etc.), then accessing them if they're packed in a JAR or WAR will be a bit difficult. Apparently Lucene requires random access to the directory listing, which isn't available (I think) with the normal JAR utilities. Right: that's why I suggested that his application extract the indexes to regular files on the disk in order to read them using Lucene. If the Lucene API is used, then writing a servlet context listener that digs out the initial indexes and places them in java.io.tmpdir in a known subdirectory is probably the way to go. This ensures that even if a WAR file is not exploded, the Lucene DirectoryReader API can get to the files. That's precisely what I was suggesting. Another way to approach this is to extend DirectoryReader and implement something like TrueVFS, but that seems to be way more work than it's worth. Yes, I think it is more work than necessary. Extracting to the fs will be the simplest solution IMO. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1 Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBCAAGBQJTstC7AAoJEBzwKT+lPKRYoKAQAKLAzj3hway9z6jhDvt1XCP1 dGk7h5/6iO4p6Rn49GYZzQmkMEQ1rVqYcmj4L/PX10UP18A3D6nAmEVCoZDCEl8H khCXkLUPsWU/zNe175eC9OLidoKuCsgDlypNR/6x2WltbEK8Vcv13XfJocCPf2Qw wSGp0+C7/bKljDg59uDmM/zMQH6kDT/n0uMiz2Y8TO7vi9rD1el0TcMg5t/ZcXqO qctXB6oWCXixdWp45U8PkZEEQML7m7bh/AbrXq9CtahVTdX2QHvEP4SzFPhoFpTC SIiGfs01B7shWMTgr0yoUVPr9BYYtxU2u1YhQM1dGCYLvQvd12gqoVo5uHQS9506 fEKGuIiLZkDDWNCQXqK7o3R6mJnThrvy8f0EPy4KSI9Glfnb42FrFkFn+W0PGBjc VDs2iJX6Bp/4Bk0YWvJyPQPAfCbnYSQow0SqK+hlraK6tMh6wRZLkqgkRAErd6h/ 5eQOg4oCrJXBm3+GZlqYl1FUUgzY9TmCoptV2G5L0Sjo7ieAkBDz6ZdE+DNJQnjV lL+JkfeHlK/zcGYr9eNP32dWglATIFw8HFUku4dgsVjecP5frPC1dVHf868RQDLt 1JxccdedEp+gYOPRCyDb8+NlQqmcTpF7gafjzr54mYrLU2MFvOGaSEXX02Ore1XG 949GyjZ3wloBB3aD3Js1 =wvlO -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

7.0.55 defined (see [1])
How do I get access to a StandardContext? CAn I cast the Context object?

A quick look in the source code will tell you why you are getting an NPE
here.
You can't add a ServletRequestListener directly. There are a couple of
ways to do this. Probably the simplest is to create a
ServletContextListener, add that directly to Tomcat's StandardContext
with addApplicationLifecycleListener() and then from that
ServletContextListener add and request and/or session listeners from the
contextInitialized() event.
You could also do this with a ServletContainerInitializer.

I tried this:
Wrapper wrapper =
Tomcat.addServlet(ctx,Greeter,GreeterServlet.class.getName());
wrapper.addMapping(/*);
wrapper.getServlet().getServletConfig().getServletContext().addListener(MyListener.class);
This results in a NPE. This makes me think I don't have access to the
context yet. I would actually think it's somewhere in this chain:
tomcat = new Tomcat();
tomcat.setPort(8080);
File base = new File(target/webapp-runner);
if(!base.exists()) {
base.mkdirs();
}
Context ctx = tomcat.addContext(/,base.getAbsolutePath());
however, it doesn't look like Context here is a ServletContext.

Look in the servlet spec for the version of Tomcat you're using (which you
didn't mention), and the JavaDoc for ServletContext (e.g., addListener).

Given you are using 7.0.54, why would you look for a tag for 7.0.55?
How do I get access to a StandardContext? CAn I cast the Context object?
Yes. It would have taken less time to try that than it did to type the
question.

tomcat8: delayed file operations with webdav
Hi, I'm about to set up a webdav server on a stock Tomcat 8.0.9 (RHEL 6.5 x86_64). To do so, I installed a dummy application with the web.xml attached to this message, altered the conf/tomcat-users.xml and started the tomcat server. Now when uploading a file it doesn't show up immediately. Which is quite confusing for an application that does a PROPFIND right after PUTting the file, which results in a 404. Or, even worse, in a 500 when trying to MOVE or COPY the file. Example: (1) dav:/webdav/ ls Listing collection `/webdav/': collection is empty. dav:/webdav/ put testfile.bin Uploading testfile.bin to `/webdav/testfile.bin': Progress: [=] 100,0% of 102400 bytes succeeded. dav:/webdav/ propget testfile.bin Fetching properties for `testfile.bin': failed: 404 Not Found [now I'm waiting for a couple of seconds] dav:/webdav/ propget testfile.bin Fetching properties for `testfile.bin': DAV: creationdate = 2014-07-01T16:29:35Z DAV: displayname = testfile.bin DAV: getlastmodified = Tue, 01 Jul 2014 16:29:35 GMT DAV: getcontentlength = 102400 DAV: getcontenttype = application/octet-stream DAV: getetag = W/102400-1404232175000 DAV: resourcetype = DAV: source = DAV: supportedlock = DAV:lockentryDAV:lockscopeDAV:exclusive/DAV:exclusive/DAV:lockscopeDAV:locktypeDAV:write/DAV:write/DAV:locktype/DAV:lockentryDAV:lockentryDAV:lockscopeDAV:shared/DAV:shared/DAV:lockscopeDAV:locktypeDAV:write/DAV:write/DAV:locktype/DAV:lockentry (2) dav:/webdav/ rm testfile.bin Deleting `testfile.bin': succeeded. dav:/webdav/ ls Listing collection `/webdav/': collection is empty. dav:/webdav/ put testfile.bin testfile.bin.tmp Uploading testfile.bin to `/webdav/testfile.bin.tmp': Progress: [=] 100,0% of 102400 bytes succeeded. dav:/webdav/ move testfile.bin.tmp testfile.bin Moving `/webdav/testfile.bin.tmp' to `/webdav/testfile.bin': failed: 500 Internal Server Error [again, waiting for a couple of seconds] dav:/webdav/ move testfile.bin.tmp testfile.bin Moving `/webdav/testfile.bin.tmp' to `/webdav/testfile.bin': succeeded.

RE: Error in DBCP Connection Pool with tomcat 6.x
Hi Filip, This error comes at some point of time on production, when the server is on load. I am using hibernate and not closing any connection manually, its all managed by hibernate and tomcat dbcp connection pool. For me it seems like DBCP is trying to close the connection which is already closed by the database server. Please refer below related links. https://issues.apache.org/jira/browse/DBCP-329 http://markmail.org/message/c2gx2xuzum4pv743#query:+page:1+mid:ncvixx4ewe7pho2x+state:results Regards, Vijendra -Original Message- From: Filip Hanik [mailto:fi...@hanik.com] Sent: 01 July 2014 21:06 To: Tomcat Users List Subject: Re: Error in DBCP Connection Pool with tomcat 6.x Looks like your code already called java.sql.Connection.close() and then attempts to use the connection again Filip On Tue, Jul 1, 2014 at 8:09 AM, Propes, Barry L barry.l.pro...@citi.com wrote: -Original Message- From: Vijendra Pachoriya [mailto:vijendra.pachor...@indegene.com] Sent: Tuesday, July 01, 2014 2:31 AM To: users@tomcat.apache.org Cc: Alok Roy Subject: Error in DBCP Connection Pool with tomcat 6.x Hi Tomcat Team, Please help me out in solving below error.
