Directory structure for servlets and webservices in one application

hi,
Can any one help me for creating servlets and webservices in one
application and deploying in Jboss 4.2.0.
I want to know exactly what is the directory structure for creating this
application and what are the additional .xml files for deploying this application.
if any one know this answere please tell the answere.

I figured out a solution - it's a problem of policies. In detail: Server1's codebase entry (file:) refers to the class directory of Server1's project. In the simple case of only Client1, which has no codebase entry, it works fine without a file permission on the side of Server1. In the complex case of Client1+Server2, which has to have a codebase entry (file:) refering to the class directory of the Server2's project on a separate machine, for exactly the same method call from Client1 to Server1 a file permission entry on the side of Server1 is needed for Server1's class directory. But WHY ???
It seems to be a little confusing with the codebase entries, many of the posts are contrary to others and to my personal experiences. Some comments given by Adrian Colley throw a little light upon some aspects. Is there anybody, who can explain the whole topic, when, why, and which part of RMI application deals with codebase entries, also in case of not dynamic code downloading ? May be there is also a reference into the java docs, which I didn't found up to now.
Thanks in advance

Moving in directory structure through servlet

Hi everyone,
I am currently using this directory structure and have 2 web applications "myweb1" and "myweb2".
/myweb1/jsp pages
/myweb1/WEB-INF
/myweb1/WEB-INF/classes
/myweb1/WEB-INF/classes/myservlet
/myweb1/WEB-INF/lib
/myweb2/display.jsp
/myweb2/WEB-INF
/myweb2/WEB-INF/classes
/myweb2/WEB-INF/lib
I have a servlet named "myservlet" in WEB-INF/classes directory(myweb1 application) as shown above. I have following entries in my web.xml file of "myweb1" webapplication.
<servlet>
<servlet-name>myservlet</servlet-name>
<display-name>myservlet</display-name>
<servlet-class>com.abc.servlet.myservlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>myservlet</servlet-name>
<url-pattern>/myservlet</url-pattern>
</servlet-mapping>
This whole application is running fine. Now I need to forward user from "myservlet" to "display.jsp" page in myweb2 application.
I am using this line in "myservlet" file.
getServletConfig().getServletContext().getRequestDispatcher("../myweb2/display.jsp").forward(request, response);
however this line is not working. Can anyone suggest me how to access display.jsp file from myservlet.
Thanks.
Rahul

As long as everything is running within the same application server instance, you should be able to access both contexts. The key is using the getContext(String URI) method of the ServletContext. From the servlet in webapp1:RequestDispatchter dispatch =
getServletContext().getContext("/webapp2").getRequestDispatcher("display.jsp");You may have to fiddle with the value in the getContext call (it should be the application context of webapp2) but you should be able to get this to work.

i thing this problem is related to web.xml ... but if this web.xml is wrong then why this web.xml gives write out put from when i checked it by browser...

Hi ,
I really dont understand why you are making such a complicated folder structure for servlet.
May be i m wrong, but if you are using eclipse everything is straight forward.
Just create dynamic web project create servlet into src & jsp into webcontent . Everything place in your
workspace thats all. Just simply call your servlet thats it

Re: issue with servlet-mapping

Hello,
i got following url pattern on web xml and it works fine on resin, however,
its gives me, java.lang.IllegalArgumentException: Invalid pattern,
is there is a anyway to fix it without altering the file structure.
<servlet-mapping>
 <servlet-name>FacesServlet</servlet-name>
 <url-pattern>/jsf/*.jsf</url-pattern>
 </servlet-mapping>

Wildcards(*) can be used either at the beginning or end of the pattern.You cannot specify wildcards in the middle of the pattern.
So, only either of these will work
<servlet-mapping>
 <servlet-name>FacesServlet</servlet-name>
 <url-pattern>*.jsf</url-pattern>
</servlet-mapping>Or
<servlet-mapping>
 <servlet-name>FacesServlet</servlet-name>
 <url-pattern>/jsf/*</url-pattern>
</servlet-mapping>

Debug a servlet

Is my understanding correct you cannot debug a servlet in weblogic8.1 - or am I
suffering from finger trouble?
I have a servlet with breakpoints that are never actioned - even though I know
I executing the code, I can edit, build and change its behaviour - but the breakpoints
are ignored!
If a project contains a runnable object like a xxx.jws file the debugger launches
as expected.
John

You might try connecting to your running server with a standard JPDA debugger like
NetBeans or Eclipse, with a project pointing to your source code. That works
fine for me. I'm assuming by implication that you're trying to use WebLogic Workshop
to do this.

WLS Servlet design question

I have a WLS servlet that connects as a CORBA client to WLE. This servlet
 receives XML requests and calls remote CORBA objects in the WLE system.
 When WLS loads a servlet and invokes the servlet's init() method, does it
 make sense to have the init() method to establish the connection to WLE and
 allow the doPost()/service() method to just invoke the calls?
 For example:
 init() {
 initialize_orb();
 resolve_initial_references();
 narrow();
 FactoryFinders();
 myMgr = findManagers();
 doPost() {
 receive transaction;
 myMgr.remoteMethod();
 return response;
 The init() method would setup the connection and doPost() would handle the
 transactions and remote method calls.
 I've found that this design works very well as long as the WLE system stays
 up and available. If WLE is restarted, the WLS servlet remains in a state
 where the init() method already had a connection and the doPost() methods
 ultimately fail. The result is that I either restart WLS or the individual
 servlets that connect to WLE
 What design issues should I pursue to make the WLS client 'impervious' to
 WLE?
 Should I use connection pools?
 Should I do the connection setup and transaction processing in doPost()
 and leave init() alone?
 Any insights would be appreciated.
 Thanks
 Rob Mason


Do you know of a reliable method to detect if my WLE connection is
 active/suspended - like the console reports?
 Once I developed a method, then I could structure my servlet as:
 init() {
 if(myClass.checkWLE()!=true)
 myClass.connectWLE();
 doPost() {
 init();
 do my processing steps here...
 checkWLE() {
 wave at WLE - does it wave back?
 connectWLE() {
 initialize_orb();
 resolve_initial_references();
 narrow();
 FactoryFinders();
 myMgr = findManagers();
 This makes much more sense - thanks for the guidance - I just need to know
 how to check to see if WLE is available...
 Thanks

Servlet not compiling

These are my 3 files
package coreservlets.beans;
class InsuranceInfo
 private String name = "No name specified";
 private String employeeID = "No ID specified";
 private int numChildren = 0;
 private boolean isMarried = false;
 public String getName()
 return(name);
 public void setName(String name)
 this.name = name;
 public String getEmployeeID()
 return(employeeID);
 public void setEmployeeID(String employeeID)
 this.employeeID = employeeID;
 public void setNumChildren(int numChildren)
 this.numChildren = numChildren;
 public int getNumChildren()
 return(numChildren);
 public boolean isMarried()
 return(isMarried);
 public void setMarried(boolean isMarried)
 this.isMarried = isMarried;
package coreservlets.beans;
import java.util.*;

import org.apache.commons.beanutils.*;
public class BeanUtilities
 public static void populateBean(Object formBean, HttpServletRequest request)
 populateBean(formBean, request.getParameterMap());
 public static void populateBean(Object bean, Map propertyMap)
 try
 BeanUtils.populate(bean, propertyMap);
 catch(Exception e)
import java.io.*;
import javax.servlet.*;

import coreservlets.beans.*;
public class SubmitInsuranceInfo extends HttpServlet
 public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
 InsuranceInfo info = new InsuranceInfo();
 BeanUtilities.populateBean(info,request);
 response.setContentType("text/html");
 PrintWriter out = response.getWriter();
 String docType = "<!DOCTYPE HTML PUBLIC \"-//W3C HTML 4.0 " + "Transitional//EN\">\n";
 String title = "Insurance Info For " + info.getName();
 out.println(docType + "<html>" + "<head><title>" + title + "</title></head>");
 out.println("<center><h1>" + title + "</h1> ");
 out.println("<ul><li>Employee ID: " + info.getEmployeeID() + " <li>Number Of Children: " + info.getNumChildren());
 out.println("<li> Married: " + info.isMarried() + "</ul></center></body></html>");
}i compile the file InsuranceInfo and BeanUtilities. Both compiled.I put both the classfiles inside coreservlets/beans.
Now I tried to compile SubmitInsuranceInfo where I have import coreservlets.beans.;
linux-9jc3:~/Development/Servlets # javac SubmitInsuranceInfo.java
SubmitInsuranceInfo.java:11: cannot access InsuranceInfo
bad class file: ./InsuranceInfo.java
file does not contain class InsuranceInfo
Please remove or make sure it appears in the correct subdirectory of the classpath.
InsuranceInfo info = new InsuranceInfo();
^
1 error
I can't understand the error because I have set the classpath to .
I am compiling from a folder called Servlet
The directory structure is
Servlet
|____SubmitInsuranceInfo.java
|____coreservlet
|
|____beans
|
|____InsuranceInfo.class
|____BeanUtilities.class

Did that but still I am getting the same error
SubmitInsuranceInfo.java:11: cannot access InsuranceInfo
bad class file: ./InsuranceInfo.java
file does not contain class InsuranceInfo
Please remove or make sure it appears in the correct subdirectory of the classpath.
InsuranceInfo info = new InsuranceInfo();
^
1 error
linux-9jc3:~/Development/Servlets #
It looks like a classpath issue
I have the classpath as . and moreover I have put both the InsuranceInfo and BeanUtilities.class in coreservlets/beans/ folder. The coreservlets dir is in Servlets dir. I am compililing the SubmitInsuranceInfo.java file from the Servlets dir.

Unregistered servlets in weblogic5.1

Hi
1)In am calling from javascript file:
parent.frames[1].hiddenfrm.action = "/servlet/login.AdminMainServlet";
For this the entry in weblogic properties file is:
weblogic.httpd.register./servlet/login.AdminMainServlet=login.AdminMainServlet
This works fine.
2) But now I am calling a servlet like this, from a javascript file:
window.open("../../servlet/Sales.ProdResrvServlet?mode=addition&act=CustomerPopup&cmpcd="+cmpcd+"&finyr="+finyr+"&searchby=sname", "CustomerPopup", "width=725, height=200, top= 5, left=60");
how can i call a unregistered servlet?..Even i commented for servletservlet, weblogic.httpd.register.servlets=weblogic.servlet.ServletServlet
My directory structure for servlets is:
C:\weblogic\myserver\servletclasses\sales
C:\weblogic\myserver\servletclasses\login
But i am calling the servlets like above,because i am shifting from someother webserver to weblogic5.1
Cheers

Unable to set configured property "/Initial.initialServices"

Hi All,
I am getting following error-
05:21:52,006 INFO [STDOUT] Unable to set configured property "/Initial.initialServices" atg.nucleus.ConfigurationException: Unable to resolve component /com/progiweb/fbconnect/pipeline/FacebookAuthStatusServlet

I have checked the config path of both components and the structure of servlet is as below-
src/com/progiweb/fbconnect/pipeline/FacebookAuthStatusServlet.java and src/com/progiweb/fbconnect/pipeline/FacebookProfileRequestServlet.java.java
And for the properties files I have created them under the path- config/atg/dynamo/servlet/dafpipeline and config/atg/dynamo/servlet/pipeline
Inside these I am keeping the FacebookAuthStatusServlet.properties and FacebookProfileRequestServlet.properties files
The path of Initial.properties is as below- config/atg/dynamo/servlet/Initial.properties
The content of Initial.properties is -
initialServices+=\
/atg/dynamo/servlet/dafpipeline/FacebookAuthStatusServlet,\

Should I need to keep the both pipeline- dafpipeline and pipeline or only one of them?
And my pipeline structure is correct or not?
How to resolve the above error?
Please help regarding this!

Prateek

The content of config/atg/dynamo/servlet/dafpipeline/FacebookAuthStatusServlet.properties is as below-

Using bean methods within JSP declaration

Is it true that bean methods will not work in JSP Methods ?
For example:
// get the bean
<jsp:useBean id="FormValidate" scope="session" class="fsm.frontendCtr.FormValidate" />
// build a new method in jsp
<%!
boolean validate(HttpServletRequest req, String submitFlag) {
FormValidate.checkMandatory("ADRNACHNAME");
%>ServletExec return:
Undefined Variable or class name: FormValidate
If i use the bean Methods outside the method it worx.
Is there a trick with which I can use BeanMethods in a JSP Method?

I know it is a silly question But unable to get HelloWorldServlet to work!

 Hello Everybody,
 I've downloaded the weblogic server today and thought of testing it with HelloWorld servlet. I made directory structure and copied under mydomain/applications/
 So finally my directory structure is mydomain/applications/myWebAPP/WEB-INF/classes/examples/servlets/HelloWorldServlet.class.
 Just onle one Hello World servlet and web.xml file which has the following entries.

 I have coded that HelloWorldServlet in my Jbuilder and copied it to that location. Then I started my default admin server, console, and opened a webpage and gave URL like this.....
