Thanks for the reply Prasanth.
I'll have to say yes. We used the configure notes as supplied in jdev 10.1.3.
and have deployed (adf runtime installer) - removed - deployed and restarted tomcat more then a few time.. I tested the 10.1.2 apps that are out there - they do not run with the 10.1.13 adf .. they work correctly when I reinstall the 10.1.2.
Reproduce the issue - lol .. well I was using 10.1.2 on my first adf jdevloper project.
add a data action - all of a sudden - everytime you went to view/add code - it blew a java exception... (that was my 2nd 'clean install' of 10.1.2) - after finding no help with that .. (found a few unanswered threads about it.. on meta link) - decided to move to 10.1.3 - after importing the project - and rebuilding (like two weeks ago) - and adding some nice improvements - it runs fine in my local jdev.
spent the last week or so trying to get it to run on the tomcat... one page of the app will open and run on tomcat (the one without any adf bindings..) the other two generate the error above.

There is no guideline I know of as this depends on the app itself.
What you should do is to deploy the application onto a test server and check the metrics of the app over a defined period of time with a defined amount of traffic.

MDS on Tomcat server

Hi,
JDeveloper 11g, Tomcat server.
I am planning to deploy the ADF Application on Tomcat server. My question is, Is it possible to configure the MDS on Tomcat server?
Please let me know.
Thanks.

Nope, not at this time. It's only certified on WLS

Integration Of Standalone Tomcat Server to JDeveloper 11gR2

Please tell me how to add & start using external standalone apache tomcat server 7.0.32 with JDeveloper IDE 11gR2.

For only Tomcat 7 is certified

Also in case you want to deploy a ADF app on Tomcat 6.x this should help -

I do have a question whether Tomcat server will work on 11.1.1.5 or not
If not which version of jdeveloper and tomcat can I use and make it work properly
Can anyone help me out?
Thanks in Advance
Santosh

I think that no one ADF version is certified to the tomcat container. If you want to deploy in tomcat you could use apache myfaces trinidad, which is the opensource ADF Faces donated from Oracle to the Apache Foundation.

Creating a link to text file in a tomcat server not working in JSP webapp

I am using netbeans to create an web application within my desktop, and then I load the build/web folder to a tomcat server to test the application. Everything works fine. However, when I try to link up my JSP pages to text files (.txt) create by the application on the server, I seem to be getting files that might be kept in a terminal.
When I get the Real path of the servlet context, I find that it is to a C:\ type file rather than a //hostname type of directory. So obviously those files are not being reached.
Does anybody know how to deal this problem?

There are a number of ways to get to the Flash Global Security settings dialog.
My favourite way is just to double click on a Captivate SWF (not the HTM file) to open it in a web browser, then right click on the playing screen to get the Flash context menu. On the context menu, click the Global Settings option.
In the web page that opens, click the link on the left to Global Security Settings.
Add the folder or drive location of your published Captivate content to the Trusted Locations.

Write Access to a file in Tomcat server via J2me Midlet

How to make write access to a file using midlet and HTTP connection?
I have text file in the Tomcat server and I am able to read it with HTTP connection using emulator, but don't have idea how to make write access to the file. I'd like to write some text to the file.

Thanks, but could you be more accurate. What methods should I use in the servlet and what methods in the midlet?
Some links which concern this subject, would be nice too. I have tried with google, no success.

How can i avoid restarting tomcat server when servlet is modified?

please advice me that how can i avoid restarting the tomcat server, whenever a servlet file is modified in my application. is their any way ?

No probs. Here's how I do things...
1. Install tomcat as normal (e.g. I install to C:\Apps\jakarta-tomcat-5.5.4)
2. Create a webapps directory in your eclipse project with the following directory structure
MyEclipseProject
   - src
   - conf
   - webapps
      - MyApplication
         - META-INF
         - WEB-INF
            - classes
            - lib
            - pages3. Set the project's output folder (e.g. bin folder) to webapps/MyApplication/WEB-INF/classes
4. Put all your jar files in the lib directory
5. Put JSPs / HTML in the pages directory (you may also want to create additional directories for TLDs, config files etc)
6. Ensure your web.xml is in the WEB-INF directory
7. Although it isn't essential I create a context.xml file and store it in META-INF, e.g.
<Context reloadable="true">
    
     <WatchedResource>WEB-INF/web.xml</WatchedResource>
     <WatchedResource>WEB-INF/conf/struts/struts-config.xml</WatchedResource>
     <WatchedResource>WEB-INF/conf/struts/tiles-defs.xml</WatchedResource>
     <WatchedResource>WEB-INF/conf/struts/validation.xml</WatchedResource>
</Context>I use this to set monitored resources that will trigger an automatic appliation reload and to configure JAAS (not shown). See the Tomcat documentation for additional information.
8. In the 'conf' directory I create a server.xml file used to configure Tomcat (you can copy the one from your <TOMCAT_HOME>/conf/server.xml).
After copying the file change appBase attribute in the host element to be the full path to the webapps directory. You can also change the HTTP and HTTPS ports if you wish
9. Download and install the Tomcat Launcher plugin from Sysdeo.
10. In Eclipse's Preferences menu you will see a new entry for Tomcat. Click this then
a. Set your Tomcat Version
b. Set your Tomcat Home
c. Set "Context declaration mode" to server.xml
d. Set the configuration file to the full path to your server.xml file created in step 8
On the "Advanced " sub page select all relevant projects to add to the Tomcat classpath
On the "JVM Settings" page add all the jars in your WEB-INF lib directory to the class path
On the "Source Path" page select all relevant projects
Now if you start Tomcat using the Tomcat icon, you will be able to remote debug your application. If you change web.xml (or any other file in your context.xml watched resources) it will automatically reload. Any changes to JSPs will automatically be picked up (providing your tell your browser not to use the page in cache - e.g. CTRL+F5 in IE)
There are some limitations that I'm still working on however. Primarily that I haven't included the Tomcat Manager application in my webapps directory, so Sysdeo cannot perform a reload. This means that if I change a source file, and eclipse auotmatically rebuilds, Tomcat doesn't pick up the change unless I either change a watched resource file (e.g. web.xml) or stop and restart Tomcat.
There's no reason why this can't be fixed, I just haven't got round to it yet.
I'm sure there are lots of other (probably better) ways of achieving the same thing. This was the first method I tried and it worked, so I stuck with it. I'm not a Tomcat config guru and I'm sure other forum users could provide some improvements should they wish.
Post if you get into trouble, however I won't be able to respond until next week.
Cheers,
Steve

Tomcat : Hlow to run more than 1 instance of tomcat server on same machine?

Hi,

If are only getting your site hosted, then, normally, the host would handle clustering (to your sepcifications, of course, but it is normally the hosts responsibility).
If i need to implement clustering and load balancing for tomcat server then do we need to go for 2 different servers for production environment?
Yes, you would need two, or more, servers.
Also please guide me on how to implement clustering and load balancing for tomcat server by running 2 instances on 2 different machine? I'm a newbie to it..
It should have no (or at least minimal) impact on the code (as long as you are using beans, sessions, and the other components properly). It is handled by the web container (by the tomcat in this case). The tomcat documentation should show how to set it up (if it supports it all, I don't know, we don't have Tomcat at work, and at home I use only a single).

The above error message i am getting in Tomcat server,i am having Oracle 11g V1..My SQL prompt is open and i have a table named "ourusers"...Can anyone kindly gimme the solution for this problem+*
Edited by: sandy on Nov 9, 2010 8:59 AM

java.sql.SQLException: ORA-00904: "SANDY": invalid identifier
Looks like the sql you are submitting is invalid.
Print out a copy of the sql you are trying to run and you will probably get:
SELECT * FROM OURUSERS WHERE usr = Sandy and password = secretThat isn't valid sql. It is missing quotes around the values you are checking.
This is the corrected sql query:
SELECT * FROM OURUSERS WHERE usr = 'Sandy' and password = 'secret'so one solution would be:
String sql = "SELECT * FROM OURUSERS WHERE usr = '" + user + "' and password = '" + pwd + "' ";However that is not optimal. It exposes your code to sql injection attack.
The better way is to use a prepared statement:
String sql = "SELECT * FROM OURUSERS WHERE usr = ? and password =?";
st = con.prepareStatement(sql);
st.setString(1, user);
st.setString(2, password);
rs = st.executeQuery();cheers,

Tomcat server is not running automatically

Hi BO experts,
I have installed SAP Business Objects XI 3.1 in my system and noticed that Tomcat server is not running in Central Configuration Manager where the status is "Stopped". If I start manually also it's not starting (In properties, the startup type is - Automatic).
So I went this path "E:\Program Files\Business Objects\Tomcat55\bin" and double clicked "startup.bat" then I am able to login into Infoview. Could please someone explain that is there any possible way to run Tomcat automatally so that i do not need to start up manually every time?
Thanks in advance!!

I'm assuming that whoever installed the Apex Listener installed it under the Apache Tomcat application server. This isn't officially supported by Oracle, but it does work. You start Tomcat by executing "startup.bat" in its bin directory on Windows or "startup.sh" on Linux or other Unix-like OSes. In Windows, it will keep running as long as the command window is open (but you can minimize it) or I believe there is a way to set it up as a service - I'm not a Windows guru. In *nix, you can add an ampersand to the command to keep it running in background, or set it up to run as a daemon.
Altogether, you probably need someone to learn more about how to run Tomcat if the person who set it up for you is no longer available. There is plenty of information on-line - just use Google or Bing.
