AW: How to avoide delete context.xml - 6.0.14

2007-08-09 Thread hans.mader

This is application related logging on application unload (struts plugin):

 com.magnasteyr.josf.InitLog4JPlugin ... try to clean up FileHandles for 
 context [XJOSF]
 com.magnasteyr.josf.InitLog4JPlugin ... Clean up FileHandles finished for 
 context [XJOSF]


Now I used the manager application for INSTALL UNDEPLOY INSTALL in my ANT 
scripts,
and I configured the context with  the antiJARLocking, antiResourceLocking 
attributes ( both true).

It works!!! 

The first thing is, that the server makes a copy of the context.xml into the 
conf/Catalina/localhost/,
and if you place a new WAR file into webapps, a reload will be done, but the 
context.xml would not be deleted...

The second thing could depend on app-related stuff (file locking), because with 
the locking flags I could 
undeploy and deploy properly.

Thanks for your assistance.

Regards, Hans.

 Hi Hassan,

 I did exactly that way you described to me,
 but the 2nd deployment still dosn't work properly.

You might want to create a very simple WAR file and see if it behaves
the same way...

 The only way that works (not always) is to delete the WAR file manually,
 wait until the webapp is undeployed and then place the war file again.

 INFO: Undeploying context [/xjosf]

Those two lines make me wonder -- since you're running Windows,
you might look at antiJARLocking and antiResourceLocking here:

http://tomcat.apache.org/tomcat-6.0-doc/config/context.html

My feeling is that this is more likely app-related than config-related
at this point; if you can create a WAR file reproducing the problem
(without proprietary material/external dependencies)  I'll be happy
to try it.

Re: 6.0.13 MySQL DBCP Example

2007-08-09 Thread David Smith


Ok... tomcat 6.0.13

1. I would merge the Context  / element from server.xml to your 
context.xml file and remove the Context element from your server.xml.  
Placing this element in server.xml is not recommended anymore as it 
means a restart of tomcat to deploy/undeploy webapps.  Also having the 
Context definition in two places for one webapp will undoubtedly cause 
problems with one overriding the other.


2. Trim any spaces in the element attributes.  I saw an extraneous space 
in the driverClassName attribute below.


3. It's not recommended you add autoReconnect=true to the mysql db url.  
It has it's uses, but not in a database pool.  Instead, use a 
validationQuery attribute in your Resource element to test and validate 
connections before your app borrows them.


4. I'm assuming the mysql-connector-java-*.jar file is stored in the 
$CATALINA_HOME/lib folder and not present in your webapp's WEB-INF/lib 
folder.


Let us know what happens.  If it still doesn't work, let us see the new 
context.xml file and be sure there isn't a Context ... element in the 
server.xml.

To whom it may correspond:

I get the following error

I have the driver mysql-connector-java-5.0.6-bin.jar copied to

My application web.xml looks like this: (exactly as the example)

In
http://tomcat.apache.org/tomcat-6.0-doc/jndi-datasource-examples-howto.htmlthere
is this instruction:

Add this in between the /Context tag of the examples context and the
  

/Host tag closing the localhost definition. If there is no such tag, you
can add one as illustrated in the 
Contexthttp://tomcat.apache.org/tomcat-6.0-doc/config/context.htmland
Host http://tomcat.apache.org/tomcat-6.0-doc/config/host.htmlconfiguration 
references, and  repeated below for your convenience.




In my own opinion this is quite ambiguous. After several search in the mail
repositories. I have this as my server.xml configuration (i deleted the
comments for easy reading)

/Context
  /Host
/Engine
  /Service
/Server

In my own opinion the problem is with server.xml, should I add something to
context.xml?
Any comment, hint or tip would be greatly appreciated.

Can not get Tomcat5 to listen to JPDA port

2007-08-09 Thread mikael . gustafsson

Hi,

I am running Tomcat 5.5 (5.5.23-0jpp.1.0.4.el5) on Red Hat Enterprise 5
and can not get Tomcat to listen to port 8000 using JPDA. Searching the
mailing list archive did not hint to any solution.

I have verified that the actual call to the JVM includes the documented
parameters -Xdebug and -Xrunjdwp (see below). Tomcat starts fine and all
the webapps works properly. The problem is that netstat does not show any
process listening on port 8000. We have the same problem on another
machine running Fedora Core 6.

Starting tomcat using jpda start results in the following running
process:

/etc/alternatives/java_sdk/bin/java -Xdebug
-Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n
-Djavax.xml.transform.TransformerFactory=org.apache.xalan.processor.TransformerFactoryImpl

-Djava.endorsed.dirs=/usr/share/tomcat5/common/endorsed -classpath
/etc/alternatives/java_sdk/lib/tools.jar:/usr/share/tomcat5/bin/bootstrap.jar:/usr/share/tomcat5/bin/commons-logging-api.jar:/usr/share/java/mx4j/mx4j-impl.jar:/usr/share/java/mx4j/mx4j-jmx.jar

-Dcatalina.base=/usr/share/tomcat5 -Dcatalina.home=/usr/share/tomcat5
