hi 2 all,
i m confused how to get connection with tomcat .

Connection Pooling in Tomcat 4.1.18

Hi,
Can anyone point me to a decent resource on how to implement Oracle connection pooling in Tomcat? I'm using the UltraSearch API's for an application and cannot get it to work correctly with the DBCP implementation that I currently use.
Many thanks,
Mark.

Mark,
What kind of Oracle Connection pooling are your refering to? Are you talking about BC4J connection pooling?

I spent many hours when i first implemented connection pooling trying to put it together. The information is scattered and the config has changed slightly from 5.0 to 5.5 etc. This is how I got it working in 5.5.17:
* server.xml seems to be a wrong place for the pool configuration if you consider it to be an application specific thing. It might be a better idea to put it into C:\tomcat55\conf\Catalina\localhost\ConfigFileForYourWeapp.xml as follows:
<Context path="/ClientLink" docBase="C:\eclipseWorkspace\PortfolioUI3\WebRoot">
      <Resource name="jdbc/testportfolios" auth="Container"
                     type="javax.sql.DataSource"
                     factory="org.apache.tomcat.dbcp.dbcp.BasicDataSourceFactory"
                     username="****" password="******"
                     driverClassName="com.mysql.jdbc.Driver"
                     url="jdbc:mysql://192.168.0.101:3306/testportfolios?user=***********&password=***********&useUnicode=true&characterSet=swedish"
                     maxWait="10000" maxActive="30" maxIdle="10" removeAbandoned="true"
                     removeAbandonedTimeout="60" logAbandoned="true" testWhileIdle="true"
                     minEvictableIdleTimeMillis="4000"
                     timeBetweenEvictionRunsMillis="60000" validationQuery="SELECT '1'" />
      </Context>* Then add the following snippet into web.xml in your webapp directory:
<resource-ref>
                <description>Database pool defined in ClientLink.xml</description>
                <res-ref-name>jdbc/testportfolios</res-ref-name>
                <res-type>javax.sql.DataSource</res-type>
                <res-auth>Container</res-auth>
           </resource-ref>* Next put the jdbc-driver jar in a place where tomcat can find it. That is common\lib. Note that the shared/lib does not work.
* Get connections in java as follows:
                try {
                     Context initCtx = new InitialContext();
                     DataSource ds = (DataSource) initCtx.lookup("java:comp/env/jdbc/testportfolios");
                     this.connection = ds.getConnection();
                } catch (NamingException e) {
                     throw new RuntimeException("Java naming exception when getting connection from tomcat pool: " + e.getMessage());
                }I hope that this helps you to save the time I lost figuring this out!

How to configure connection pooling in tomcat?

how to configure connection pooling in tomcat and how to use the connection pooling in the jsp and servlets?

thanks for the reply, i have configured the connection pool settings in the tomcat.
I created a class with static method, which will return the connection object.
whenever i need the connection object, iam invoking the static method, once its usage is over iam closing thew connection..
is it the right way of using the connection object in the web application.

How to use JDBC Connection Pools in a standalone application?

Hi, there,
I have a question about how to use JDBC Connection Pools in an application. I know well about connection pool itself, but I am not quite sure how to keep the pool management object alive all the time to avoid being destroyed by garbage collection.
for example, at the website: http://www.developer.com/java/other/article.php/626291, there is a simple connection pool implementation. there are three classes:JDBCConnection, the application's gateway to the database; JDBCConnectionImpl, the real class/object to provide connection; and JDBCPool, the management class to manage connection pool composed by JDBCConnectionImpl. JDBCPool is designed by Singleton pattern to make sure only one instance. supposing there is only one client to use connection for many times, I guess it's ok because this client first needs instantiate JDBCPool and JDBCConnectionImpl and then will hold the reference to JDBCPool all the time. but how about many clients want to use this JDBCPool? supposing client1 finishes using JDBCPool and quits, then JDBCPool will be destroyed by garbage collection since there is no reference to it, also all the connections of JDBCConnectionImpl in this pool will be destroyed too. that means the next client needs recreate pool and connections! so my question is that if there is a way to keep pool management instance alive all the time to provide connection to any client at any time. I guess maybe I can set the pool management class as daemon thread to solve this problem, but I am not quite sure. besides, there is some other problems about daemon thread, for example, how to make sure there is only one daemon instance? how to quit it gracefully? because once the whole application quits, the daemon thread also quits by force. in that case, all the connections in the pool won't get chance to close.
I know there is another solution by JNDI if we develop servlet application. Tomcat provides an easy way to setup JNDI database pooling source that is available to JSP and Servlet. but how about a standalone application? I mean there is no JNDI service provider. it seems a good solution to combine Commons DBCP with JNID or Apache's Naming (http://jakarta.apache.org/commons/dbcp/index.html). but still, I don't know how to keep pool management instance alive all the time. once we create a JNDI enviroment or naming, if it will save in the memory automatically all the time? or we must implement it as a daemon thread?
any hint will be great apprieciated!
Sam

To my knoledge the pool management instance stays alive as long as the pool is alive. What you have to figure out is how to keep a reference to it if you need to later access it.

Connection pooling in Tomcat

Hello all,
I've been using tomcat 5.0.27 and for quite sometime now using the connection pooling on tomcat as well.
I configure DataSource(no.of connections,username, password etc) by logging into tomcat admin console.
But what I've seen is it adds datasource configuration data into server.xml - including the username and password to the database(which will be supplied to the driver by the container when creating a connection). But I don't want the username and password to be present in the xml file (i.e. in clear text format). Is it possible to somehow give the password and the username when requesting for a connection i.e. datasource.getConnection and not while configuring the pool and still get it working?
Please guide me.
Thanks,

Oh yeah. I've already tried it. It always seems to
get the connection with the credentials that I gave
while configuring the datasource. Whatever password I
pass in the call to getConnection - it is being
ignored.Do you have one already set in the server.xml? If so, try removing it (and restarting the server).
But an implication - the server might just decide to
have say x connections in the pool on startup. So if
you havent given the uname/password for the
database(when you configured the datasource) and give
the credentials only when getConnection is called in
your code - how will the server have those x
connections in the pool on startup?Probably won't It may wait to store the connections to the pool until x number of calls to the getConnection method are made (like a lazy initialization). But I don't know, just getting around to testing now.
I have people telling me that having uname/password to
the database in server.xml doesn't augur well for the
security of data in the db :(It could be true, but
1) The only people to see the server.xml are those who work on the server. The server.xml (or better the context.xml if you can avoid editing the server.xml altogether) is not accessable from the web.
2) My strategy was always to create many different levels of access to any particular database. Some with Read Only access and limited table viewability, and then progressively higher access. You give the server.xml only the access they absolutely need. IE, if they are just retrieving data from a couple tables, make a read-only user with the ability to see only those tables...
Don't take my word for it though. I have never really tried to do the whole ultra-secure thing, my apps are not important.

Then i stop the tomcat web server and start it again.
In jsp page i have included the following code:
Context ctx=new InitialContext();
Context envctx=(Context)ctx.lookup("java:comp:env");
DataSource ds=(DataSource)envctx.lookup("jdbc/myoracle");
Connection con=ds.getConnection(); ----->(In this line an error occured that Connection class cannot be found.)
please help me how to create a connection pooling and rectify the error in conneciton.
Thanks in advance

Connection pool + db2 + tomcat 5 migration problem

I succeded in using connection pooling in Tomcat 4.0.x and IBM db2 6.xx and 7.xx.
Now I am trying to use Tomcat 5 (released with netbeans 3.6) and I have some problems.
I migrated the context information from server xml to context xml, but I have a username-password problem
<Context docBase="D:\j2sdk_nb\NetBeans3.6\progetti\Pegaso2" path="/pegaso2" reloadable="true">
<Resource auth="Container" name="jdbc/pegaso61" type="javax.sql.DataSource"/>
<ResourceParams name="jdbc/pegaso61">
<parameter>
<name>factory</name>
<value>org.apache.commons.dbcp.BasicDataSourceFactory</value>
</parameter>
<parameter>
<name>driverClassName</name>
<value>COM.ibm.db2.jdbc.app.DB2Driver</value>
</parameter>
<parameter>
<name>url</name>
<value>jdbc:db2:pegaso61</value>
</parameter>
<parameter>
<name>username</name>
<value>userxxxx</value>
</parameter>
<parameter>
<name>password</name>
<value>passxxxx</value>
</parameter>
</ResourceParams>
</Context>
When running my servlets, i get this error:
Exception in PoolDB2Connector.getConnection():org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory, cause: [IBM][CLI Driver] SQL1403N The username and/or password supplied is incorrect. SQLSTATE=08004
So it means ( I think !!) that the web-application i getting the right driver ( i got a db2 error) but is having problem with username and password.
I am using getConnection() method ( with no argouments) in my PoolDB2Connecto class (according to the documentation the getConnection(user,password) method is not supported)
I have a parallel installation of netbeans 3.5.1 (tomcat 4.0.6) with the same parameters (username, password, url...) and is still perfectly working
Any help will be greatly appreciated,
Andrea

OK, I found the problem !
It is not due to any configuration issue, but it is due to a BUG in tomcat 5.xx
I reproduced the problem with mysql db server other than db2 db servver.
The problem is the presence of the $ sign in the users' s password !!!!
Probably the xml parser rading server.xml introduce some error finding $ sign.
The problem is still present in the 5.028 version of tomcat.
If i modify user's password REMOVING $ sign, everything is OK
Perhaps $ sign should be escaped (?!?)

How do I get connected to a server on my network via an IP address? When I try to open in a URL and login as a registered user with proper login it errors out saying there was a problem with connecting to the server?

I am new to Mac...How do I get connected to a server on my network via a hyper link IP address path? When I try to open in a URL and login as a registered user with proper login it errors out saying there was a problem with connecting to the server?

Some of the following is going to use some technical terms — this area is inherently somewhat technical.
If you don't understand some part of the following reply, please ask.
Is this your own OS X Server system on your own network, or is this some other server within some larger organization?
You're posting this in the OS X Server forum, which is a software package that allows OS X systems to provide web-based and many other services; to become servers.
If it's your OS X Server on your network, then the network and DNS configurations are suspect, or the server is somehow malfunctioning or misconfigured. This is unfortunately fairly common, as some folks do try to avoid setting up DNS services.
If it's a larger organization and somebody else is managing the server and the network, then you'll probably need to contact the IT folks for assistance; to learn the network setup and DNS requirements, and if there's a problem with the server itself.
The basic web URL "hyper link IP address path" — without using DNS — usually looks something the following, where you'll need to replace 10.20.30.40 with the IP address of your server:
http://10.20.30.40
UptimeJeff has posted a URL that specifies the AFP file system; an OS X file share. That's used if you're connecting to an Apple storage service somewhere on your network. You might alternatively need to specify smb://10.20.30.40 or such, if it's a Windows file server. (There can be additional requirements for connecting to Windows Server systems, too.)
If there's local IT staff available here, please contact them for assistance. If these are your own local systems and your own local OS X Server system, then some information on the server will be needed. (If you're on a NAT'd network, you'll also need to get DNS services configured and working on your local OS X Server system and your network — you'll not be able to skip this step and reference ISP DNS servers here — or things can and usually will get weird.)

I am unable to get my bluetooth working message says "make sure car mutli media is in range" how do I get connected?

I am unable to get my bluetooth working on my phone. the message says "make sure car mutli media is in range" how do I get connected and what does that mean?

Have you tried a soft-reset ? Press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider if it appears), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.
