Info: Memorizing Deployment Descriptor

[Anand Wadhwani]

Somebody, (if I recall correctly 'Sanjay') had submitted here a URL for memprizing SCWCD things, here is the URL again.
http://sengsation.freeprohost.com/SCWCD_Memorization.html

And here is complete web xml, you can copy/paste and keep with you as for single glance on all elements before appearing in exam:

<display-name>A Simple Application</display-name>
<!------------------------------------------------------------------------->
<!--
If multiple servlets / JSPs need to have access to same parameter, then we can define init parameters at web application level, these parameters are called context parameters. Container stores these parameters in ServletContext object after instantiating the first servlet called on this application after server started and before calling init() method of that servlet.
-->
<context-param>
<param-name>databasename</param-name>
<param-value>devpro1</param-value>
</context-param>
<!------------------------------------------------------------------------->
<!--
Deploy time constants like email-id, or data source name can be specified as servlet init parameters in DD (web.xml). Container stores these parameters in a ServletConfig object after instantiating the servlet before calling init().
-->
<servlet>
- - - - -
- - - - -
<init-param>
<param-name>email</param-name>
<param-value>[e-mail]</param-value>
</init-param>
</servlet>
<!------------------------------------------------------------------------->
<!--
In servletcontext via context-parameter we can have only string values. To have a complete object e.g. DataSource we can create listeners and add to DD (web.xml)
In event of context initialization, we can read init parameters from context object stored in event, and we can create whatever object we want and store back in context as an attribute, which can be accessed by servlet using getattribute method of context.
-->
<listener>
<listener-class>com.example. MyServletContextListener</listener-class>
</listener>
<!------------------------------------------------------------------------->
<!-- Session timeout can be configured in DD. (Always indicates minutes) -->
<session-config>
     <session-timeout>15</session-timeout>
</session-config>
<!------------------------------------------------------------------------->
<!-- You can define the init parameters for converted servlet in following manner: -->
<servlet>
<servlet-name>MyTestInit</servlet-name>
<jsp-file>/TestInit.jsp</jsp-file>
<init-param>
<param-name>email</param-name>
<param-value>[e-mail]</param-value>
</init-param>
</servlet>
<!------------------------------------------------------------------------->
<!-- To disable scripting in a JSP (to encourage EL) following jsp-configuration can be done in DD: -->
<jsp-config>
<jsp-property-group> 
<url-pattern>*.jsp</url-pattern>
<scripting-invalid>true</scripting-invalid>
</jsp-property-group>
</jsp-config>
<!------------------------------------------------------------------------->
<!--
To ignore EL in a JSP (to run older JSP with higher JSP specifications as in old JSP there could be EL syntax template text), the following jsp-configuration can be done in DD:
-->
<jsp-config>
<jsp-property-group> 
<url-pattern>*.jsp</url-pattern>
<el-ignored>true</el-ignored>
</jsp-property-group>
</jsp-config>
<!------------------------------------------------------------------------->
<!-- Specifying geneic error page configuration in DD: -->
<error-page>
<exception-type>java.lang.Throwable</exception-type>
<location>/errorPage.jsp</location>
</error-page>
<!-- OR we can specify specific exception handler JSPs too: -->
<error-page>
<exception-type>java.lang.ArithmeticException</exception-type>
<location>/arithmeticErrorPage.jsp</location>
</error-page>
<!-- OR we can specify specific error code handler JSPs too: -->
<error-page>
<error-code>404</error-code >
<location>/NotFoundErrorPage.jsp</location>
</error-page>
<!------------------------------------------------------------------------->
<!-- The old (before JSP 2.0) way to map a taglib uri to a TLD file in DD: -->
<jsp-config>
<taglib>
<taglib-uri>randomThings</taglib-uri>
<taglib-location>/WEB-INF/myFunctions.tld</taglib-location>
</taglib>
</jsp-config>
<!------------------------------------------------------------------------->
<!--
If user does not specify the resource but the path only in the URL, container tries to search for welcome file in that path. Multiple welcome file names can be configured in DD, container searches the file in same sequence mentioned in the DD. The file name must not start/end with a slash. Here is the syntax for configuring welcome files in DD:
-->
<welcome-file-list>
<welcome-file>index.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
<!------------------------------------------------------------------------->
<!-- Servlet initialization can be configured in DD. Here is the syntax: -->
<servlet>
<servlet-name>snetservlet</servlet-name>
<servlet-class>Walgreens.snet.servlet.SnetServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<!------------------------------------------------------------------------->
<!-- EJB related DD configuration: -->
<ejb-ref>
<ejb-ref-name>ejb/LocalCustomer</ejb-ref-name>
<ejb-ref-type>Entity</ejb-ref-type>
<home>walgreens.snet.ejb.CustomerHome</home>
<remote> walgreens.snet.ejb.Customer</remote>
</ejb-ref>
<!-- Here is a little different syntax for referencing a local EJB (A bean running in same JVM): -->
<ejb-local-ref>
<ejb-ref-name>ejb/Customer</ejb-ref-name>
<ejb-ref-type>Entity</ejb-ref-type>
<local-home>walgreens.snet.ejb.CustomerHome</local-home>
<local> walgreens.snet.ejb.Customer</local>
</ejb-local-ref>
<!------------------------------------------------------------------------->
<!-- Declaring an application's JNDI environment entry: -->
<env-entry>
<env-entry-name>rates/discountRate</env-entry-name>
<env-entry-type>java.lang.Integer</env-entry-type>
<env-entry-value>10</env-entry-value>
</env-entry>
<!------------------------------------------------------------------------->
<!-- Mime type configuration in DD: -->
<mime-mapping>
<extension>mpg</extension>
<mime-type>video/mpeg</mime-type>
</mime-mapping>
<!------------------------------------------------------------------------->
<!--
Once the users/roles are defined by vendor, the application has to specify specific roles used by the application through security-role element in the DD. Here is the syntax:
-->
<security-role>
<role-name>Admin</role-name>
<role-name>Member</role-name>
<role-name>Guest</role-name>
</security-role>
 
<login-config>
<auth-method>BASIC</auth-method>
</login-config>
<!-- Defining resource/method constraint: -->
<security-constraint>
<web-resource-collection>
<web-resource-name>UpdateRecipe</web-resource-name>
<url-pattern>/Beer/AddRecipe/*</url-pattern>
<url-pattern>/Beer/ReviewRecipe/*</url-pattern>
 
<http-method>GET</http-method>
<http-method>POST</http-method>
</web-resource-collection>
 
<auth-constraint>
<role-name>Admin</role-name>
<role-name>Member</role-name>
</auth-constraint>
 
</security-constraint>
<!------------------------------------------------------------------------->
<!--
A programmer may use different roles inside code, e.g.
if (request.isUserInRole("Manager")) { � }
 
in this case an Admin / Deployer person need not modify all the security roles, instead of that they can define and use role links inside DD. Here is the syntax:
-->
<servlet>
<security-role-ref>
<role-name>Manager</role-name>
<role-link>Admin</role-name>
</security-role-ref>
</servlet>
 
<security-role>
<role-name>Admin</role-name>
<role-name>Member</role-name>
<role-name>Guest</role-name>
</security-role>
<!------------------------------------------------------------------------->
<!--
Declaring form based authentication and creating custom login screen. DD entry below:
 
Login page HTML must declare a login html form with following:
1. action= 'j_security_check'
2. input text name= 'j_username'
3. input password name= 'j_password'
-->
<login-config>
<auth-method>FORM</auth-method>
<form-login-config>
<form-login-page>/loginPage.html</form-login-page>
<form-error-page>/loginError.html</form-login-page>
</form-login-config>
</login-config>
<!------------------------------------------------------------------------->
<!-- To implement data integrity and confidentiality, user-data-constraint element should be used inside security-constraint element. Here is the syntax: -->
<security-constraint>
<web-resource-collection>
<web-resource-name>UpdateRecipe</web-resource-name>
<url-pattern>/beer/UpdateRecipe/*</url-pattern>
<http-method>POST</http-method>

<role-name>Member</role-name>
</auth-constraint>
 
<user-data-constraint>
<transport-guarantee>CONFIDENTIAL</transport-guarantee>
</user-data-constraint>
</security-constraint>
<!------------------------------------------------------------------------->
<!-- Associate the filter with whichever resource it is written for through DD, here is the syntax: -->

<filter-class>Walgreens.snet.filters.CacheFilter</filter-class>
</filter>
<filter-mapping>

Hope this would help people!

Anand,

Thanks! This really helps.

[Karthik Rajendiran]

Hello Anand,
I am also preparing for scwcd like you.
Can you tell me what all things are u referring.
I am reading the HFSJ
2. Servlet,JSP, JSTl specs

Do We Have any mocks, certification quick guides ?
What needs to be done for the preparation.
Can you forward some mocks and guides or sites to download those.

One more thing , we dont have E.patterns much covered in HFSJ. Do we have to refer some more book

[Anand Wadhwani]

Hi Karthik,

Apart from HFSJ Book and Specifications, giving at least 700-750 mock questions is MUST to secure good score in the exam.

I am planning to do Enthuware Mock Exams, it has around 450 questions. Apart from this I am going to refer following links:

http://enthuware.com/purchaseall.html
http://www.j2eecertificate.com/
http://www.javabeat.net/

Here is one more URL that helps in memorizing the WAR Deployment Descriptor elements:

http://e-docs.bea.com/wls/docs61/webapp/web_xml.html#1013332

Though this link from WebLogic server, but good for any app server since the format of WAR deployment descriptor 'web.xml' file is part of J2EE specification and not vendor-specific.

[Rajagopalan Rajendran]

Guys,,,

R u poeple able to access the below link ???
http://sengsation.freeprohost.com/SCWCD_Memorization.html

hi folks,
I am preparing for SCWCD and am planning to clear it before this month end. I didn't know we can specify these many tags in web.xml. Its truly difficult to remember all those tags. Is the order of the tags also important? Hope someone would send me those PPTs u guys mention to me too.

[Yuriy Zilbergleyt]

[I]<filter-mapping>
<filter-name>My Filter </filter-name>
<url-pattern>/Recipes/*.do</url-pattern>
<dispatcher>FORWARD</dispatcher> <!-REQUEST/FORWARD/INCLUDE/ERROR -->
</filter-mapping>[/I]

Can't you also do something like

<filter-mapping>
<filter-name>My Filter </filter-name>
<servlet-name>MyServlet</servlet-name>
<dispatcher>FORWARD</dispatcher> <!-REQUEST/FORWARD/INCLUDE/ERROR -->
</filter-mapping>

?
