Re: Tomcat, ActiveMQ, 'jndi.properties' file problem
Hi,
sorry, I forgot to note, that the resources in the context.xml and
web.xml files are replacements for the jndi.properties. I'm using
Tomcat's build-in JNDI.
It looks like you're using one Queue with the name listenerDestination.
So, try the following:
META-INF/context.xml:
Context
...
Resource
name=jms/ConnectionFactory
auth=Container
type=org.apache.activemq.ActiveMQConnectionFactory
description=JMS Connection Factory
factory=org.apache.activemq.jndi.JNDIReferenceFactory
brokerURL=ssl://localhost:32450
brokerName=localhost
useEmbeddedBroker=false /
Resource
name=jms/listenerDestination
auth=Container
type=org.apache.activemq.command.ActiveMQQueue
factory=org.apache.activemq.jndi.JNDIReferenceFactory
physicalName=dms.PublicLogQueue /
...
/Context
WEB-INF/web.xml:
...
resource-env-ref
resource-env-ref-namejms/ConnectionFactory/resource-env-ref-name
resource-env-ref-typejavax.jms.ConnectionFactory/resource-env-ref-type
/resource-env-ref
resource-env-ref
resource-env-ref-namejms/listenerDestination/resource-env-ref-name
resource-env-ref-typejavax.jms.Queue/resource-env-ref-type
/resource-env-ref
...
And in the code you can obtain the Destination using
try {
InitialContext ic = new InitialContext();
Context ctx = (Context) ic.lookup(java:comp/env);
ConnectionFactory cf = (ConnectionFactory)
ctx.lookup(jms/ConnectionFactory);
Connection conn = (Connection) cf.createConnection();
conn.start();
Session s = conn.createSession(false,
Session.CLIENT_ACKNOWLEDGE);
Destination d = (Destination)
ctx.lookup(jms/listenerDestination);
MessageProducer mp = s.createProducer(d);
mp.setDeliveryMode(DeliveryMode.PERSISTENT);
TextMessage tm = s.createTextMessage();
tm.setText(Foo);
mp.send(tm);
tm = s.createTextMessage();
tm.setText(Bar);
mp.send(tm);
conn.close();
} catch (Exception e) {
e.printStackTrace();
}
...
If you want to run ActiveMQ under Tomcat, not as standalone broker,
specify useEmbeddedBroker=true in the context.xml.
The Resource tags can be also placed in the server.xml, but I have bad
experience with JDBC resources there, so I didn't try it.
Try the configuration above. This must work for you!

Re: Properties file problem
Hi Vikas,
some details:
I see you're correctly using the getClass.getResource() (I'm using
getServletContext().getResourceAsStream() or
getServletContext().getResource()). But, Why are you creating
resources? You see all the war content in the host OS filesystem
because of unpackWars=true. This is because of performance (I hope)
and if you set this to false, Tomcat will *read* resources (also
classes and anything else) from the WAR file directly! You are mixing
two things together: one are resources (they are using URL instead of
File) and on the other side Host OS FileSystem (the File objects).
So, you store database connection parameters in the property file. I
see two options to solve your problem:
1. Move the property file outside the resources if you want dynamic
creation. For example: temporary directory, any other directory which
location can be hard-wired as initial parameter in the web.xml file.
2. Use Tomcat's database pooler. You give more performence (if you're
not using your own database connection pooler)!
Please explain what you want to do, what's your goal...
Have a nice day

If you're going to run the two apps inside the same JVM, do you even need to write a file? You should be able to just pass String objects from one to the other. The output side is a database write, and part of our design criteria was to be able to stop and start the database without interfering with data flow from the remote sites into the central office. So we write the data to disk and acknowledge the successful receipt of the data to the sites at that time. Then we can read the data out of the disk file and write it to the database indpendently. and what about to use JMS (ActiveMQ for example)? Does fileWriter.flush() do almost the same thing? No guarantee - there are two levels of buffering going on. The flush() API pushes the stream information out to the file system, but does not require that it actually be written to disk. Only the sync() does that. I don't know if the results of the flush() are visible to other processes in NTFS. They are, as far as I understand it.

Solution: Connecting from Tomcat to ActiveMQ
Hi all friends,
I spent two days solving this problem and because there is not so
complex informations about this in the internet, I find this helpful.
I hope, this will help.
I need to connect from Tomcat web application into the standalone
ActiveMQ broker. I repeat -- standalone broker. But I found several
problems. First, the configuration:
Sun Java 5 (06)
Apache Tomcat 5.5.15
ActiveMQ 4.0-M4
The first:
- start ActiveMQ using the bin/activemq bash script (sorry, I'm using
Linux, for windows use appropriate bat/cmd scripts and remembere the
(back)slash hell).
So, You can connect to the broker using jconsole:
jconsole service:jmx:rmi:///jndi/rmi://localhost:1099/jmxrmi
Second, start tomcat with the simple servlet sending TextMessage using
JMS objects obtained from JNDI.
But, there is a bug, in the M4 ActiveMQ distribution.
Then you close the connection (the close() method), your connection to
the broker is closed but the `Connection already closed' Exception
during `cleanup()' is thrown. This exception does not throws to the
Servlet code itselfs, but is secreted in the tomcat's another thread,
so you can see it only in the log or in the Eclipse console.
WARNING: Cleanup failed

And, if you does not call the close() method, no Exception is thrown
and the connection (the socket) will stay connected. If you trigger
the servlet (for ex. using the GET program), you will see in the
jconsole more and more unused connections.
The solution is simple: Upgrade ActiveMQ to the latests SNAPSHOT.
The latest SNAPSHOT is working very very good.
And one note. You can see in the ActiveMQ log the Exception:
java.lang.ClassNotFoundException: mx4j.tools.naming.NamingService
Simply download latest binary distribution of the mx4j project and
copy the mx4j-tools.jar into the $ACTIVEMQ_HOME/lib. Cool.
And, If you are looking for something like this problem (Tomcat +
ActiveMQ + JMS + JNDI), here is my web application configuration

Re: Mapping different different folders in a webapp to different urls
Hi, and what about to write a servlet filter? I have my test domain with several virtual hosts IN CNAME to localhost (or any other IP where is Tomcat listening) in my DNS. I wrote an simple filter which parses virtual host name (request.getLocalName() -- always contains full computer name from requested URL) and forwards request to specified servlet (according to configuration) using RequestDispatcher... Note that I'm not using JSP, I'm using servlets only because I have my own CMS which is vhost, domain, context-path, servlet-path independed and must support various output formats. This is working for me. Sessions are OK, because I don't need cross-vhost navigation... PETR On 3/13/06, Per Johnsson [EMAIL PROTECTED] wrote: Hi!

If a hacker want to detect your site, I think he will test all posibles JSP Jsp jSP and others. That's not where security problem lies: Let's assume your public site is at http://yourserver/yourwebapp/index.jsp if casesensitiveness is deactivated and you are using a case sensitive filesystem (like the microsoft ones), accessing NTFS, FAT -- mayby they are case sensitive, but the filesystem layer not. Try to create two files in one directory; one named a.txt and the second A.txt. The billboard ocures! On Unix systems is this possible -- Makefile is not makefile;-) http://yourserver/yourwebapp/index.jsP will point to same filesystem ressouce, but with one exception, it will not be handled by jsp engine and requester will simply get the jsp source instead of generated html (a jsp source could contain potentially critical informations like database connection informations) More dangerous, suppose your application have an admin interface located at http://yourserver/yourwebapp/admin/ with a security-constraint in web.xml mapped to 'admin/*', any anonymous user can have his browser point at 'AdMiN/' and will have access to admin interface without authentification, bypassing securities! Of course it's not a problem if you don't have jsps, neither servlets, nor security constraints, that if you are serving static content.

Re: JDBC DataSources with SYBASE Adaptive Server Anywhere
Hello Thomas,
thank you for your informations! I will order ASA developer edition
and learn new database;-) Now, I'm looking for a database which
provides internationalization features; specially ORDER BY [(var)char
| text] column and I have no success:
ASE and localization -- it's a workaround.
PostgreSQL -- it's the same. You must define locale during database
storage creation:-(
Firebird -- currently I have no experience:-(
Oracle -- expensive:-(
So, maybe ASA will solve my problem
Regarding T-SQL: I don't know how you, but I find T-SQL great... Some
constructions are interesting
Regarding JDBC: Maybe the native library causes your problems. I'm
using only pure-Java drivers located in the common/lib with no
problems.
Regarding DBCP: I found DBCP classes in the stack traces during my
driver's debugging. And finally -- there is naming-factory-dbcp.jar in
the common/lib...
Regarding Tomcat and data sources: I found this more then obscure. I
have one question: If you write a webapp which uses database; where
shall I define the datasource names? Hardwiring is not a solution. And
put them (the definitions) into some configuration file into the
webapp war file?? Ofcourse, Tomcat have the admin app in which you can
define app-specific database cources... But Sun Java System App server
not... There are in the SJSAS only global resources... I must learn
more...
So, many many thanks for your informations; I'm sorry that I didn't help you:-(
Have a nice day

Hi Petr,
Thanks for your feedback. It still does not work for me, no matter where
I put the damn JAR file. So I will use my own pooling class directly in
my webapp based on Apaches DBCP which is part of Jakarta Commons. It is
probably faster then fiddeling with this bloody driver configuaration.
I currently should use the pool from JSP's and not from Java code.
However, it should not make a difference.
Just for your information regarding ASA and ASE: ASA is a database
originally written by a company called WATCOM in Canada. I use the
software for more then 10 years and it is one of the best DB engines
money can buy. Even with large databases (several GB in size) it is
faster then MS SQL Server. ASE is only faster if there are hundreds of
concurrent users, but ASE has still many limitations in SQL syntax, db
space management, datatypes etc. Also it only understands T-SQL while
ASA understands both T-SQL and ANSI SQL.
Regarding JDBC: jConnect is a driver provided from SYBASE. It works on
ASE as well as on ASA and uses the Tabular Data Stream TDS protocol.
jConnect is quite slow and does NOT support scrollable cursors, but it
is a pure java, level 4 driver. JDBCODBC.IDriver is a NATIVE library
driver (level 3). It is NOT using bridge, it is using a native DLL or
.SO on UNIX. To connect one needs to setup a ODBC datasource which may
be painful, if you have to redistribute a client. (You need to integrate
the entire ODBC stuff in your setup program). This driver is relatively
new (compared to jConnect) and was introduced with ASA 8 (I think).
Currently we have ASA 9.x. Earlier version only could use jConnect.
Cheers
Thomas

Hi,
I studied something about Sybase ASA and here are my pieces of knowledge:
- ASA is, unlike ASE, ODBC based insted of TDS
- the JDBC drivers are generic JDBC-to-ODBC bridge and can be used to
access _any_ database throw ODBC
- the JDBC drivers are not freely downloadable (I didn't find any)
- You can access ASA also throw jConnect (TDS based Sybase's JDBC drivers)
This solution is functional but the speed (power) is less -- Sybase
does not recomand to use jConnect drivers.
So, I tried to use my ASE under Tomcat (Currently, I'm successfuly
using PostgreSQL). The following solution works fine under Tomcat
standalone and Tomcat under Eclipse.
Small HOWTO for Tomcat 5.5.15/jdk1.5.0_06/Linux:
1. Locate your existing JDBC driver, or try use jConnect
(http://www.sybase.com/products/middleware/jconnectforjdbc)
2. Copy the driver jar(s) into ${CATALINA_HOME}/common/lib
3. Create your META-INF/context.xml
4. Make the resource references in the WEB-INF/web.xml
5. Use the data source(s) in your code
I saw the `Cannot load JDBC driver class' and it seens the drivers
must be in the common/lib directory.
Finally, here is my context.xml, web.xml and example lines using the database
Hope this helps

Of course I experienced with the settings in the autoexec.bat file from the tomcat installation. Kind Regards D.

Re: Assistance required
Try upgrade from GNU Java (which is the default JVM in the Fedora
distribution) to the Sun Java 5.
GNU Java has too many issues because of is not in the final version (I
remembere) :-(

Class.forName(com.mysql.jdbc.Driver);
Connection con =

ResultSet rs = st.executeQuery(select * from admuser);
while(rs.next())

System.out.println(rs.getString(1));

con.close();

when i compile the program with javac jdbc.java no eror is given however
when i run the program i get the following errors :
java ./jdbc

Hi,
You can visit the site www.coreservlets.com , it will help to configure
the Tomcat.
You would be able to get the examples of server.xml and web.xml too.

Re: default webapp not understanding
Hi, no, you must delete whole the original contents of the existing directory webapps/ROOT and deploy your own ROOT.war web application. Be careful. The `ROOT' word is case sensitive. The default URL mapping is: http://[machine]:[port]/[context]/[servlet]/ where machine is currently localhost, port is 8080 by default context is in the context.xml file and usualy is the same as the web application name servlet: it's defined in web.xml servlet-mapping tag If you deploy your application as ROOT application, the context path will be only `/' (slash). Chuck explains it to me (thank you Chuck!) one month before. Look into the mailing-list history. Hope to help you Have a nice day!

For 5.5.x, the default webapp is the one located in webapps/ROOT.war or the webapps/ROOT directory. Can I somehow configure this to go to the above $TOMCAT_HOME/webapps/mywebapp/index.html? Deploy your webapp in webapps/ROOT, not webapps/mywebapp. I get confused when the doc states that the entry in the host must also have a context entry? Can anyone clarify that. Where does it say that? The current doc states that you _can_ nest Context tags inside Host, not that you must. Putting Context tags in server.xml is strongly discouraged these days, but not all of the doc has caught up to that fact. Here from the docs Exactly one of the Hosts associated with each Engine MUST have a name matching the defaultHost attribute of that Engine. That attribute for simple Tomcat installations is localhost, which you already have. Nothing to do with contexts. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

If this JDBC connection is only used by the workflow web app, defining it in web.xml is actually preferred.
