Disable automatic context reloading in tomcat on web.xml chaning

Hi all,
is there a way to disable automatical reloading of webapp if web.xml is changed?

It should be enabled in latest tomcat version as I cannot DISABLE it. Reloading on Servlet changing is enbaled by adding reloadable="true" to context-tag in server.xml

Tomcat vs web.xml

I know it is offtopic, but i just can't find out what to do to tomcat that it must not be restarted each time when I change web.xml. Course only after restarting it applies new params :(
Thanks in advance.

No, as far as I know you have to restart Tomcat to pick up changes to web.xml

ejb-name into web.xml automatically

Hello all,
I follow the OC4J's tutorial in >>Servlet Developer's Guide<< using Jdeveloper 903.
there is an EJB session bean named HelloBean.
From UML Diagram, I can get it, and write the HelloServlet.java to invoke session bean.
now it is Ok. Jdeveloper online help says that EJB reference <ejb-ref> can be written into web.xml file,
but it doesn't do it. I manually insert <ejb-ref>...</ejb-ref> into web.xml.
and change <ejb-name> and <ejb-ref-name> in ejb/HelloBean.
I want to know how to do this automatically by Jdeveloper 903.
and how to change session bean's <ejb-name> from HelloBean into ejb/HelloBean?
Thanks.
Wu JianHua.

Automatic insertion of ejb-ref in web.xml whenever EJB dependencies are included in WAR deployment profile.
Select Tools | Preferences
Select Deployment in the left hand tree
Select the check box for "Automatically Fill in <ejb-ref> elements in web.xml
You can hit F1 hel on the above panel to view the help.
From help system
Automatically Fill In <ejb-ref> Elements in web.xmlBy default, JDeveloper automatically inserts corresponding elements to the web module deployment descriptor file, web.xml, whenever EJB dependencies are included in the WAR profile. If an EJB dependency is subsequently removed, however, JDeveloper will leave the elements in web.xml instead of removing them. Clear this checkbox to disable automatic insertion of elements in the web.xml file. Clearing this field prevents extraneous <ejb-ref> elements from appearing in the web.xml. However, do this with caution, since you'll have to make sure that the web.xml file is complete and accurate before deployment.

Define a context parameter not using web.xml

Dears,
With a web.xml file, it is possible to define a context parameter available in the web app via de ServetContext.getInitParameters method.
Is it possible to define a context parameter not using the web.xml file ? Can I, in a java Class, init a custom context parameter ? (for exampel, init as a context param a key/value pair read from a property file).
PS: the need is that the value (hmac key) currently define in the web.xml needs to be updated monthly. Apparently, under WebSphere (the app server we are using) changing the web.xml of the deployed app it not enought for it to be taken into account.
Sincerely,
Beno�t Bertrand

Is it possible to define a context parameter not
using the web.xml file ? Can I, in a java Class, init
a custom context parameter ? (for exampel, init as a
context param a key/value pair read from a property
file).Does it necessarily have to be a value retrieved through the context param ? AFAIK, there's no way you could programatically 'set' an init param, which going by the name, 'init param' is quite understandable.
You could define this value in a property file and read it in, in the init method. You should provide a mechanism to reload the new value after 'x' days. One approach is a Timer that does the job, do have a look at SteveJLuke's recommendations on the same in this thread

help me out

In addittion to following the steps as indicated by the above URL, make the context entries in the
app_root/META-INF/context.xml file .
As I encountered lots of probelms in settingup the JNDI datasource via server.xml or web.xml file
To be precise , do follwoing:
1. Make META-INF directory and add context.xml file to include following:
<Context path="/app_name" docBase="app_name"
debug="5" reloadable="true" crossContext="true">
<Logger className="org.apache.catalina.logger.FileLogger"
prefix="Test_log." suffix=".txt"
timestamp="true"/>
<Resource name="jdbc/yourDB"
auth="Container"
type="javax.sql.DataSource"/>
<ResourceParams name="jdbc/yourDB">
<parameter>
<name>factory</name>
<value>org.apache.commons.dbcp.BasicDataSourceFactory</value>
</parameter>

<parameter>
<name>maxActive</name>
<value>100</value>
</parameter>

<parameter>
<name>maxIdle</name>
<value>30</value>
</parameter>

<parameter>
<name>maxWait</name>
<value>10000</value>
</parameter>

<parameter>
<name>username</name>
<value>dbuser</value>

</parameter>

<parameter>
<name>url</name>
<value>jdbc:mysql://localhost:3306/yourDB?autoReconnect=true</value>
</parameter>
</ResourceParams>
</Context>
2. In the web.xml include following:
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"

Edit web.xml programmatically

And another question
Can I edit the web.xml from the web application, in session been for example. I want the admin user to add roles from the web application page and grant them to users.
Then it should be created automatically in the database
and in web.xml.
Maybe it is possible to add it in data base but not to web.xml.
is there a way?
Thank you, I hope to get answers soon from you.

There probably are options to do this, but all of them(the ones i know of atleast), are either too cumbersome or an over-kill.
Why do you want to add security roles/grants for "users" in your "web.xml" ? Apart from compromising security, I think your definitely going to violate some standard there.
As a general note: In the end, all xml files are parsed and converted to beans. XML files merely are a place holder for convenience. If required you can figure out the bean holding this information and accordingly change the info it.
Alternatively if you're still persistent in adding this security information on your web.xml the only plausible way i can think of is old-school. Get a file writer and add/edit this info. But this idea is too crazy to even suggest.
Best suggestion: Design your application in such a way, so as to pick the info from a DB and accordingly handle.
Cheers,
K

Security constraint in web.xml

Hi All
I want to set a security contraint to verfity my system user, I know I need to put the following section into the tomcat created web.xml. But I dont know where is the web.xml on my Tomcat 4.1.24, because i found many web.xml files in different directory.
Q1) Sorry I know this is a silly question, but can u tell me which web.xml is the one I need to edit in order to set my the security constraint?
Q2) Instead of editing the created Tomcat web.xml, can I create my own web.xml and put it in <Tomcat_Homw>/webapps/ROOT/WEB-INF. This is just only for the security constraint towards my system.
Many many thanks

you need to do it for every web-app... thats why there is one web.xml file for each! There is a thing in CATALINA_HOME/conf/server.xml that u can uncomment to enable 'single-logon' which means u cna log on once and be authenticated for every web-app...
root isn't a web-app i don't think... so therefore u can't restrict access to it (someone correct me if wrong)... I don't know what u mean by restricting access to your 'system'

Automate creation of web.xml file for tomcat 4.1.29

hi , this is with ref to Tomcat 4.1.29, if i am correct, each Servlet in the application has to be mentioned in the web.xml file for the Tomcat to know about it. Is there any way to automate the creation of web.xml file , depending on the contents of the Servlet folder of the application. Any way to escape from writing each Servlet name in web.xml file.

Hello,
Maybe you should check if you can use Ant tool to do
that. I am not sure if it can help u.
Zeph.

It will, specially if used in conjunction with XDoclets :

XDoclet has Ant tasks to generate web.xml files.

Reload web-inf/web.xml file without restarting tomcat

Please help me if any one have a solution .
I am doing development in jsp, servlet. I am using tomcat5 as a webserver.
i want to reload web-inf/web.xml file without restarting tomcat.

From the tomcat admin page you can stop/start and refresh individual applications. See the tomcat documentation. Which, when you have a question about tomcat, you should always do first.

How to get Context paramters out of Tomcat web.xml file

The Documentation at Tomcat seems to suggest:
Context initialization parameters that define shared
String constants used within your application, which
can be customized by the system administrator who is
installing your application. The values actually
assigned to these parameters can be retrieved in a
servlet or JSP page by calling:
String value =
getServletContext().getInitParameter("name");
Now I want to write a jsp, where the user enters his username and pwd, and this contacts a jdbc connection bean. I want to store the driver name in the web.xml file. Now can some1 please suggest a method as to how I can extract this (It ain't that straightforward as suggested in tomcat doumntation. You cannnot call the above method ithout Servlet Initialization (actually to say ithout HTTP Connection). I succeeded when I had written a servlet, but can some1 please suggest an alternative (bcoz othrwise just to extract that I am writing a servlet).
Hope I am clear.
Thanks in advance.

Edit your web.xml file and add these entries,
<context-param>
<param-name>dbUrl</param-name>
<param-value>jdbc:oracle:thin:@server5:1521:pl2java</param-value>
</context-param>
<context-param>
<param-name>dbDriver</param-name>
<param-value>oracle.jdbc.driver.OracleDriver</param-value>
</context-param>
Place the above entries in between your already existing <web-app> and </web-app> tags.
Now in your jsp, you can use, <% application.getInitParameter(); %> and in servlet, getServletContext().getInitParameter();
Hope this helps.

Security constraint in Web.xml of tomcat

Hi
I have a web-application running on tomcat . Inside the context folder i have several directories having some pre-defined configuration files . But the user is able to directly access them by typing the path including the fileName in the URL ( I have disabled the listings property however)
How can i prevent accessing the specific files .... I tried using
<security-constraint>
<display-name>Security constarint</display-name>
<web-resource-collection>
<web-resource-name>Java Application</web-resource-name>
<url-pattern>/folder/*</url-pattern>

</auth-constraint>
</security-constraint>
<login-config>
<auth-method>BASIC</auth-method>
<realm-name>OnJava Application</realm-name>
</login-config>
This seems to be working fine , but when the user enters the wrong security info thrice , 401 error page is coming instead i want my custom page . Hence i configured an error page for 401 code which overwrited the earlier behavaiour ie.. that BASIC authentication popup is not coming
Can any one let me know how to go about this

Hi ,
I have tried adding the following into web.xml but the security feature just doesnt work and the user can go to any page without any restriction.

I've had the same issue bugging me since installing Snow, er, lion, er, cat, er, cougar, er, Mountain Lion. Incredibly ANNOYING.
It's stupid stuff like this and reverse scrolling that really turn long-timer users off. I'm personally glad Forstall got fired for blunders such as these.
I'm serious peeved that turning off iCloud Documents & Data actually deletes documents and data locally. That's just incredibly stupid.
MANY thanks mende1 for the answer on how to fix it.
