How to specify min/max memory on Tomcat 3.3?
Hi, Is there anyway to specify the minimum and maximum memory on Tomcat 3.3? What is the default maximum memory? Thanks! nyhgan. - Do you Yahoo!? Take Yahoo! Mail with you! Get it on your mobile phone.
Problem with WebApp Classloader using remote Jmx initialization of the Web module.
I'm trying to create the WebAppContext remotely with JMX (Tomcat 5.0.27, JDK
1.5)and doing something like this:
public void deployApplication(String context, String path) throws
CoreException {
init();
try {
ObjectName webmodule =
new
ObjectName(DOMAIN+:j2eetype=WebModule,name=//localhost/+context+,J2EEAppl
ication=none,J2EEServer=none);
mbsc.createMBean(org.apache.commons.modeler.BaseModelMBean, webmodule,
new Object[] {org.apache.catalina.core.StandardContext}, new String[]
{java.lang.String});
mbsc.setAttribute(webmodule, new Attribute(docBase, path));
mbsc.setAttribute(webmodule, new Attribute(defaultWebXml, web.xml));
mbsc.setAttribute(webmodule, new Attribute(engineName, DOMAIN));
mbsc.setAttribute(webmodule, new Attribute(delegate, new
Boolean(true)));
mbsc.invoke(webmodule, init, new Object[] {}, new String[] {});
//mbsc.invoke(webmodule, start, new Object[] {}, new String[] {});
} catch (Throwable e){
throw new CoreException(new Status(IStatus.ERROR, TomcatPlugin.PLUGIN_ID,
IStatus.ERROR, Cannot create the application context for +context, e));
}
}
This code initialize, but does not starting the WebContext. When I force the
startup from JConsole it fails on NoClassDefFoundError. The class it fails
to find is in WEB-INF/lib directory.
I see that the classloader is initialized as well. But I'm not sure how to
assing it to Web App module.
Do I have to explicitly set loader atribute?
Thanks,
Alex.

Re: Tomcat will not run JSPs
Sorry to bother you again Jacob. But heres what I have found out, first time into a program, the database opens, updates and closes all with a Status of 0 and 0... Enter another program,and the database opens with a Status of SqlCode = -1 and SqlState = 08002 (connection name in Use). And then, any other attempt to access database results in -1 and 08000 thereafter. By backing out to Tomcat manager, stopping and restarting the application, seems to take care of the 08002, but then it reappears right after you do an initial open/close.. Is there anything at all that you are aware of, that Tomcat keeps a resource open? On my close, I do a COMMIT followed by DISCONNECT ALL.. Im so sorry for bothering you.

Uninstall Tomcat. Grab the .zip file distribution and extract it to a directory *without spaces*. Now, change the value of CATALINA_HOME to the new location of Tomcat. Reboot. The reboot is sometimes not necessary, but many times it is in order for your environment variables to be recognized. Just be safe and reboot. Now you are ready to run. The question is, which way are you running it? I suggest running using the startup.bat file. You can create a shortcut to this on your desktop (same with shutdown.bat) to make things easier. Since you seem to be a relative newbie to Tomcat (and possibly to programming???), I don't suggest trying to set up the windows service, especially since the service.bat currently doesn't include tools.jar in the classpath and will cause JSP not to compile. Why this hasn't been changed by the Tomcat developers is beyond me. I've reported it many a time and it is simply ignored. Baffling! Anyway, you should be set to go. Seriously, Tomcat is one of the simplest apps out there to set up. If you are having trouble, you might want to take a class of some sort to get up to speed on some of this rather than banging your head against the wall for as long as you have been.

Where did you add the -security? Did you move the catalina.policy file?
System.getSecurityManager() returning null is generally taken to mean
that the JVM is not running under the manager at all: this is obvious, I

manager up, the system's behavior will change. In fact, I never
considered the trouble one could cause calling setSecurityManager at
runtime when there was no manager in effect (as opposed to trying to
override an existing policy, for which there's a permission check).
The AccessControlException means that after you started the manager,
some bit of code tried to get its ContextClassLoader, and it did not
have the appropriate runtime permissions. Are the policy file entries

Re: Tomcat will not run JSPs
sounds to me like you aren't using connection pooling. Rather, you are opening a connection each time, but not fully closing the connection. Additionally, your database is probably set to only support 1 connection for this particular user at a time. You might want to check into allowing more connections and using connection pooling so that they stay open constantly so it isn't so expensive to use them.

Re: SecurityManager
Mike,
You do not need to post your question specifically to 3 different
people. It's all on one list, just ask one question. Not only that, but
you seem to have hijacked two threads in the process. Create a new thread
for a new question. Does a post about JSP's or a post about the Tomcat
SecurityManager sound anything like they have to do with databases? I
don't think so, and it ought to be obvious even to the most newbie or
newbies. You ought to know that you risk being ignored if you continue
this behavior on the list. Yes, we all understand you have a problem that
needs solving, but you are less, not more, likely to get an answer with
this line of questioning.

Mike,
You do not need to post your question specifically to 3 different
people. It's all on one list, just ask one question. Not only that, but
you seem to have hijacked two threads in the process. Create a new thread
for a new question. Does a post about JSP's or a post about the Tomcat
SecurityManager sound anything like they have to do with databases? I
don't think so, and it ought to be obvious even to the most newbie or
newbies. You ought to know that you risk being ignored if you continue
this behavior on the list. Yes, we all understand you have a problem that
needs solving, but you are less, not more, likely to get an answer with
this line of questioning.

Hi Benjamin, Im sorry to bother you, but Im desperate and you seem
pretty
knowledgeable re Tomcat. Im using the Windows Installer version
5.0.27..
Could I ask you a question, I added my application thru the Application
Manager... went to the Company Logon
screen,which opens MySql database, updates it, and closes it.
All
successfully. I then go to the User Login screen,which does the
same functions as above, open, update, closeand on my Open database,
I
get a 08002 (connection name in use). Any subsequent call gives an
08000.
By backing out to Tomcat manager, stopping and restarting the
application,
seems to take care of the 08002, but then it reappears right after you
do
an initial open/close.. Is there anything at all that you are aware
of,
that Tomcat keeps a resource open?
On my close, I do a COMMIT followed by DISCONNECT ALL..
Im so sorry for bothering you.
By the way, Im running Servlets.. Do you have any idea what my
problem
may be, Im totally new to this type
of programming, and extremely frustrated, cause my App works fine in
CGI
format under a different Web Browser, only problem is, CGI is
extremely
slow.. I need it to work in Servlets
Thank You for any help you may be able to offer me...

Where did you add the -security? Did you move the catalina.policy file?
System.getSecurityManager() returning null is generally taken to mean
that the JVM is not running under the manager at all: this is obvious, I
know, but it also indicates the converse. So if you start a security
manager up, the system's behavior will change. In fact, I never
considered the trouble one could cause calling setSecurityManager at
runtime when there was no manager in effect (as opposed to trying to
override an existing policy, for which there's a permission check).
The AccessControlException means that after you started the manager,
some bit of code tried to get its ContextClassLoader, and it did not
have the appropriate runtime permissions. Are the policy file entries
you indicated are all that is in your policy file?

I'm trying to get an application I have to use the SecurityManager
object from Tomcat.
I've added the -security to my startup so that it is enabled.
When I do a System.getSecurityManager() it returns a null object.
If I try and create my own SecurityManager and set it via
System.setSecurityManager, I get: 004-08-26 14:07:47

there can be two things to change: if ur using tc5 you can change your dbcp resource via yourcustomapp.xml (conf/catalina/localhost/) Resource name=jdbc/yourcustomname auth=Container type=javax.sql.DataSource/ ResourceParams name=jdbc/yourcustomname parameter and then in your web.xml param-namejavax.servlet.jsp.jstl.sql.dataSource/param-name param-valuejdbc/yourcustomname/param-value On Sun, 29 Aug 2004 14:29:22 -0700, Jack Lauman [EMAIL PROTECTED] wrote: I'm using the following code in a servlet to get a JDBC connection: Context ctx = new InitialContext(); DataSource ds = (DataSource) ctx.lookup(java:comp/env/jdbc/DBNameDS); Connection conn = ds.getConnection(); It works fine... but I would like to be able to substitute DBNameDS with the actual name of the ds as defined in the web.xml file.

tomcat 5.0.27 xml schema or DTD for server.xml
Hi, I am running tomcat 5.0.27. I'm looking for a copy of the xml schema for the server.xml file. I've looked on the jakarta website and in the 2.4 servlet spec, but can't find it, Maybe there's only a DTD at this stage, Anyone know where to find it?

RE: tomcat 5.0.27 xml schema or DTD for server.xml
You wouldn't find it in the servlet spec, because it's specific to Tomcat. Check the archives, but as I recall, there's no published grammar for the server.xml: It's parsed in non-validating mode by the Digester. A DTD wouldn't work because the attributes for an element are arbitrary (to accomodate user implementations of the Catalina interfaces). I appreciate the idea: I wrote a schema for the 4.1.x server.xml when I wanted one to validate against, but it was kind of a bear.

RE: tomcat 5.0.27 xml schema or DTD for server.xml
Hi, Actually my intentions are modest. I want to validate whether the tags in server.xml are properly nested. I've had difficulty with this in web.xml before (when setting url-mappings). That's besides the general goal of improving my understanding of tomcat's configuration terminlogy. L.
