Re: Problems with graphics on Tomcat 5.5.9
You need to install the X11 libs for X. The Java Advanced Imaging API calls the X libs on Linux to get font and scaling data. You can try setting the JVM java.awt.headless property to true. This will work for some instances. But installing the X libs installed on your server is a more reliable option. To set your java.awt.headless as true use the following line. System.setProperty(java.awt.headless, true); System.setProperty(java.awt.headless, true); Mauricio Fernandez A. wrote: Hello I have a web App with some jsp´s showing graphics generated by jfreechart, in my windows dev station it works fine but in my linux production server it was working fine to some days ago and now it doesn´t.

Re: Tracking Datasource Connection Usage?
JWM wrote:
Two things you can do here.
1. Set both removeAbandoned and logAbandoned parameters to
true. This will reclaim most lost connections. And log a trace of what
code called a connection that was never closed.
2. Use a finally block to close all of your Resultsets and
connections. This will insure they are closed even if your code throws
an exception.
Example :
ResultSet rs = null;
Connection con = null;
try {
}
catch(Exception e) {
}
finally {
rs.close();
con.close();
}
I started getting exceptions saying no connections were available on my JDBC
datasource (org.gjt.mm.mysql.Driver). The pool was definitely large enough
to handle the load. So it appears that I'm not freeing the all the
connections as I should. I noticed that I did not have the
'removeAbandoned' flag set on the Resource tag. Changing that has
apparently fixed the out of connections problem. But I really want to clean
up the code and fix it the right way. I've got the close() statements in
place. But obviously, I'm missing some of them somewhere. Is there any
process for logging/tracking allocating and freeing connections (and absence
thereof.), available connections, etc? Or are there any methods I can call
to give me this type of debug info? What's the recommended way to debug
this?
Thanks.

Re: how to Upload file
They are saying that to do file upload you probably want to use a prebuilt frame work/ package. You can do it all your self manually but you would be using up a lot of time to build a basic task. The 3 most popular and easiest to use are : 1. Using Struts. If you are not already using struts then this would probably be way more than you are looking for. http://struts.apache.org/ 2. The Jakarta Commons file upload project. This provides all the basic capabilities and lets you support file basic file upload options in under 20 or so lines. This is what I use and like. http://jakarta.apache.org/commons/fileupload/ 3. com.oreilly.servlet.

But I would really like to create a Singleton class that could hand out connections based upon

Does that make sense. Only problem is, I cannot figure out how to transfer the

Anyone know?

Re: No Host matches server name localhost error
The error your getting is more likely saying that you computer can not resolve localhost as domain name. If so it would have nothing to do with your server config. Try using the loop back IP(127.0.0.1). If this is happening on a windows box you may want to run a check for viruses or spyware. If it is Linux make sure you have a listing for localhost in your /etc/hosts file.

Re: Does Tomcat run better on Linux or Windows?
Wow this seem likely to start flame war. Since it is written in Java there is really not much of a difference. The only thing that comes to mind is that you have to reboot windows every time you need to make a change to the CLASSPATH, JAVA_HOME, or TOMCAT_HOME variables which can be a pain. I will also throw in that it is my personal option(NOTE: For any extremists on the list I said my option. Not an absolute fact. Just one guys experience) that you spend a lot less time maintaining Linux. This is mainly because Linux is so modular that you can uninstall everything but the parts you want. So the only things I have to keep up with and patch are the Kernel, MySQL, Apache, and Tomcat. No GUI, no extra services, etc. Chad Lester wrote: Is Tomcat more stable on Linux or Windows 2003?

Re: JAVA_HOME beginner
Did you download the windows installer for Tomcat5.x? Or just Tomcat in a zip file. If you did not get the installer you need to manually set JAVA_HOME. Or go back and download the acuall windows installer, which of the two will be much eaier. I am not sure about XP. In Win2k you 1. Right click on My Computer 2. Select Properties 3. Click on the Advanced tab. 4. Click the button labeled Environmental Variables 5. Look to see if JAVA_HOME under the System Variables. If not add it. The syntax for the path has to be dead on perfect. If is wrong at all it will not work. Also be aware that with windows when you make a change to the Environmental varaibles you have to reboot before Windows will see the change. One other thing to check is make sure you downloaded the JDK version 1.4.2 or newer. If you downloaded the JRE Tomcat will not be able to run. ganesan malairaja wrote: i am using win XP. tomcat 5.0.xx and jdk1.4_02 i tried running several jsp pages ..it resturns this errors Unable to find a javac compiler; com.sun.tools.javac.Main is not on the classpath.

Re: configure tomcat
Tomcat 5.x requires JDK 1.4.2 or newer. I would get 1.5.4 or what ever the newest JDK is. Especially if you will be doing any GUI development. You do not need to configure anything in Tomcat if you are ok with its default values. If you want to make any changes to Tomcat you can do so by making changes to the values in the server.xml file in Tomcat/conf/ All of these are basic questions that are covered in the Tomcat Docs pages. http://jakarta.apache.org/tomcat/tomcat-5.0-doc/index.html Joshua Pereira wrote: hello im a beginer . im using windows XP, tomcat 5.0.28, MySql 4.1 Can anyone tell me what version of JDK should i use and how do i configure my tomcat. can anyone show me an example configuration for windows XP .

Re: newbie with a short question
Couple of things 1. You will get better responses on this list if you review the posting guide at. This post is way to vague to get specific answers. So most people are not going to respond to it. http://jakarta.apache.org/site/mail.html 2. If I follow the description correctly you are uploading a batch file to tomcat. Then loading a page with a link to that batch file. Then you are clicking on the link and it is displaying contents of the batch file. If I followed all of the correctly that is exactly what should happen. If you are clicking on an Http link that posts to a web server that server is going to try to return the requested resource. If you need to execute a file locally from Tomcat then you need to use one of the Java method calls to execute native files. This by the way is usually a bad idea. Is what ever your batch file is doing really a process that you can not recreate in java? If I have misunderstood entirely which seems likely then you may want to repost the question formated in accordance with the posting guilds lines listed above. Posts to support forums should always include a detailed step by step lise of the process that creates the failing, copies of relevant configuration files(Saying you deleted some comments in a config file does not really help. We need to see it.), and the lines of code that are believed to be failing. nick sturm wrote: ok, I have done the two things on that page: renamed the serverlet and deleted the comments around the cgi section of the web.xml config file.

Re: jndi question
Sean, One thing that stands out in your message is that the conext.xml file was placed in the META-INF folder. Is it also in Tomcat Folder/conf/Catalina/localhost/ as the module name? i.e. If the context path name of your webapp is /seansApp the context.xml file should appear in this folder as seansApp.xml. The context.xml file is stored in META-INF during development but needs to be placed in Tomcat Folder/conf/Catalina/localhost/ folder for deployment with the file name of the context path.

org.xml.sax Exceptions mean that one of the XML files is not properly formated. Specifically this one is telling you that you have an unterminated Context tag somewhere.

Re: jndi question
Sean, Where the files you deleted in WEB-INF/lib or commons/lib? You should have naming-factory.jar and naming-resources.jar in common/lib/. Or somewhere in the class path. WEB-INF/lib is just another location in the class path you can add extra packages your apps may need access to. Libraries placed there will be loaded first when multiple instances of the same packages occurs. i.e. if you have say naming-factory.jar in both /commons/lib and WEB-INF/lib it will load the package in WEB-INF/lib/. The other thing that is significant about WEB-INF/lib/ is that Tomcat will load an instants of every package in it for each web app. So for example if you have 5 web apps that all use mysql-connector.jar. And you put mysql-connector.jar in WEB-INF/lib/ for all of those apps Tomcat will load 5 instances of mysql-connector.jar. Where as if you put it in commons/lib/ it will only load one instance saving you RAM. I put a copy of any third party package my web apps call. I do this because I want them to be completely portable. That way if I copy them to anther server I do not have to worry about what packages I may have forgotten to add to commons/lib/. The result is I have fewer deployment problems but I am using more RAM than I absolutely need to. A typical app for me will have the following in WEB-INF/lib mysql-connector-java-3.1.7-bin.jar commons-dbcp-1.2.1.jar commons-fileupload-1.0.jar commons-httpclient-2.0.2.jar commons-pool-1.2.jar commons-collections-3.1.jar itext-1.3.jar itext-xml-1.00.jar Looking though your stack trace it looks like you have a JSP page called test.jsp calling com.transcriptionportal.utils.DBManager.init(). And that there is a package there that uses the org.apache.naming.NamingContext class. I am assuming that this is where you can calling the pooled connection and Tomcat needs one of those two JAR's to do the JNDI call.

Re: jndi question
Yes you can use JNDI with out using JSTL. But the only way to configure it is to define the JNDI resources in the web.xml and context.xml files. Technically you should be able to use the globally defined JNDI resources in server.xml, and I have seen configuration set ups doing it when googling. But could never get them to work. This highlights another area of seemingly unneeded complication in Java/Unix development.

What issue? If you are needing to get a page to load a PDF you have two options. 1. Set an A tag with the source value set to the location of the PDF. This will load the PDF in the entire window assuming that they have the PDF plug in installed. 2. The other option is to use frames and have the PDF load as the source of one of the frames. This will load the PDF in one of the frames and give you space around it if you need it. Did that answer your question? If not we would need at lest a hint of what problem is.

Are you saying you are taking the PC that runs Tomcat home with you and it does not work at home? Or are you trying to connect to Tomcat running at the office from anther PC at home? If it is the second one then you need to use the actual IP or domain instead of just localhost. What other services is Tomcat connecting to?

Can you verify that you can connect to them over the VPN? i.e. Log in or connect to them manually with out Tomcat over the VPN to make sure you have access.

Re: Advice for Hosting Many Individual Webapps?
My solution for this is not elegant. I run 8 apps on one instance of Tomcat and it will be growing to 12 soon. All of those apps are set with autoReload set to true. When I need to update something I manually copy the individual class or JSP file to the proper folder to over write the existing ones. So I never need to take Tomcat down unless I update a library in commons/lib which is almost never. I also when in a hurry use the deployer to restart individual web apps so they do not all go down. This works to a point but has the obvious pitfalls. First Tomcat is wasting processing time constantly checking to see if it should reload any of the modules. And second if I update a class file or JSP page that depends on another updated class or JSP file I forgot to copy over then that app will throw exceptions like crazy. It also means I have to manually set the config files like the context.xml files which is very error pron. Any one else have other ideas? -Original Message- From: Seth Ladd [mailto:[EMAIL PROTECTED] Sent: Tuesday, August 16, 2005 3:12 PM To: Tomcat Users List Subject: Advice for Hosting Many Individual Webapps? Hello, We are finding outselves hosting more and more individual webapps, all running on Tomcat 5.5.9 w/ JDK 1.5. Each of these webapps is developed and deployed on a separate schedule, and the number and frequency of app deployments is increasing. The frequency is so much that the uptime of all of our applications is affected as we continually take down Tomcat servers in production to deploy a new application (or new version of the application). Because hot deploy does not work (the old favorite OOM error w/ too many redeploys), we bounce the Tomcat server for every redeploy. To avoid taking down all of our applications when we need to redeploy a single app, we've begun to deploy each application to their own Tomcat instance. All of these instances are fronted by a single Apache server handling vhosts, logging, etc. We're just curious how common this setup really is. We know we are in an uncommon position, with so many webapps (approaching 20, and growing very fast). We don't want to put all our eggs in one basket, so to speak, so we've begun to split out individual tomcat instances. Anyone else have to handle numerous webapps, with frequent deploys, and have to keep uptime for all apps as high as possible?

Re: Advice for Hosting Many Individual Webapps?
I think I missed something here. Are you not still bouncing Tomcat here? If so isnt the service still going down? What is the benifit of changign the ports around?

Hello, We are finding outselves hosting more and more individual webapps, all running on Tomcat 5.5.9 w/ JDK 1.5. Each of these webapps is developed and deployed on a separate schedule, and the number and frequency of app deployments is increasing. The frequency is so much that the uptime of all of our applications is affected as we continually take down Tomcat servers in production to deploy a new application (or new version of the application). Because hot deploy does not work (the old favorite OOM error w/ too many redeploys), we bounce the Tomcat server for every redeploy. To avoid taking down all of our applications when we need to redeploy a single app, we've begun to deploy each application to their own Tomcat instance. All of these instances are fronted by a single Apache server handling vhosts, logging, etc. We're just curious how common this setup really is. We know we are in an uncommon position, with so many webapps (approaching 20, and growing very fast). We don't want to put all our eggs in one basket, so to speak, so we've begun to split out individual tomcat instances. Anyone else have to handle numerous webapps, with frequent deploys, and have to keep uptime for all apps as high as possible? We hesitate to put all webapps in one tomcat, because to deploy one app means we have to take down all of our apps. This is becoming unacceptable.

Re: Advice for Hosting Many Individual Webapps?
Sorry still not following. If Tomcat is being restarted how do you not have start up time? Is it that you have two instances of Tocmat and you are having the firewall just point to one instance while you bounce the second? If so is there an advantage to doing that over clustering? George L. Sexton wrote: The net effect is that users have to re-login, but there is no down time. They get bounced, but can immediately log back in. Right now, startup time for my hosted machine is running in the area of 5 minutes. So, I'm eliminating a 5 minute startup cycle. I'm running 60 virtual hosts on one machine (P3 600). I'll be moving to a P4 3.0GHz this weekend, but I hope to get up to 200 virtual hosts per machine. Any way you cut it, startup time is a killer.

Re: webapp loading order...
Well Tomcat is not likely to do this for you so you would probably need to structure the app2 to wait for a trigger from app1. You could have app1 POST to a servlet in app2 and have that be the trigger for the dependent steps. Or have app1 write to a file that app2 will poll until it sees a trigger value it is set to look for. Joe R. Lindsay wrote: You may be right in a perfect world, but well... I don't think we'll get there this week. I have a 3rd party app that I am dependent on and I'd prefer to avoid the cost of rmi across multiple Tomcat instances. I don't give up easily so I am going to try to use the Tomcat manager app and just script the starting and stopping of applications rather than leave that to the vagaries of Tomcat. I am sure to find this imperfect but being an old ops guy, but control feels more deterministic to me...and I've enough datacenter surprise for this life.

Re: Webapp suddenly not available
I would try removing the context.xml file, if there is one, and replace the web.xml with a default one. Then restart Tomcat. If you still get the 404 error when calling just JSP pages and there are no errors in the catalina.out file then the problem is very likely in the syntax of the URL being used. If this does work then the problem is mostlly in the web.xml file. Possiblly in the context.xml but not liklly. The context.xml file can be found in Tomcat DirTomcat\conf\Catalina\localhost\Name of deployment dir.xml Sample of a defulat web.xml File ?xml version=1.0 encoding=UTF-8? web-app xmlns=http://java.sun.com/xml/ns/j2ee; xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance; xsi:schemaLocation=http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd; version=2.4 session-config session-timeout 30 /session-timeout /session-config welcome-file-list welcome-file index.jsp /welcome-file /welcome-file-list /web-app /Sample of a defulat web.xml File Vsevolod (Simon) Ilyushchenko wrote: Brian Cook wrote on 08/16/2005 10:36 AM: WOW that looks like a lot lot of unneeded complication.

It is only needed if you need to call a servlet, define a resource like JNDI, or set a context value. Is the 404 error from Tomcat or Apache? Do you get the 404 error when you try to connect one of the servlets directly? Brian, The error is from Tomcat - if I go to port 8080, I also see it.

Re: Out of memory
You would probably be better served looking at what you can change in the app so it does not require so much RAM. It has been my experience that when I get an out of memory error it is because I was forgetting to close an object, or calling too many large objects globally, or reading in too much data into a result set. Of all my web apps only one requires the heap size to be raised to the 512MB limit. It loads multiple 1MB - 10MB overlays them on one another and then dynamically overlays a lot of font specific anti-aliasing text. Unless the application is doing similarly demanding you would probably be better severed by debugging the app to see what is using so much RAM. If you are making a development error like say forgetting to close an object something everyone on the list has done it is always better to learn of errors as early as possible so you do not carry it over to other apps. A lesson I have learned the hard way.

Re: WEB-INF/lib/myjar.jar doesn't contain file xyz...
When I get this it is usually either because I miss spelled the library I was calling or because the permissions on the jar file are too restrictive to allow Tomcat to open it. i.e. I logged in and transfered the file as root and the tomcat user can not read it. I actually have a script now that I run every time I upload new files that changes the owner and group of all the files in the webapps dir to the tomcat user and group. t.n.a. wrote: Tomcat (5.5) seems reluctant to load a .jar file from the WEB-INF/lib directory. Specifically, it seems to load tapestly.jar (as the error is displayed in a tapestry exception page), but it doesn't seem to want anything to do with cayenne.jar. The reported error is that a file in cayenne.jar is missing, which is plain wrong: when you unzip the .jar, it's there. Also, I've got another application that also uses cayenne.jar - on the same tomcat server - and it just works. Am I missing something here?

Re: adding mime-type
If you are calling it though a servlet I believe you will still need the set the MIME type in the HttpResponse object with a call like response.setContentType(text/html); I am not sure how you would do it for a JSP page. Unless you just went for the inelegant option of % response.setContentType(text/html); % You would clearly need to replace text/html with the MIME type you set up already.

[Tomcat] Tomcat fails to give complete HTTP responses
I have an instance of Tomcat5.5 running on JDK1.5.3 on RedHat9(Kernal 2.4). About every 7 - 10 days Tomcat stops fully responding to HTTP requests. By that I mean Tomcat does seem to give some response to the browsers because they(the browsers) do not return an error, and they never time out. It will just sit there with a blank screen waiting for the response. I originally assumed there must be a loop some where is a servlet that was not ever terminating. How ever when I bring up a process list it shows the java thread using 0% - 1% so I am guessing it is not simply an out of control loop. Stopping and then restarting Tomcat resolves the problem for another 7 - 10 days or so. Until it happens again. The catalina.out log does not show any errors taking place. Running top shows that 64MB of RAM available, that the processor is 99% idle. What else should I be looking at to track down what I have done wrong? Has anyone else seen symptoms like this?
