Cannot invoke default servlet through invoker????

Does someone can help me with this exception? what it mean? How to solve? I'm using TomCat 4.0.6
The code i'm using...
public void doGet(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException{
String url = "/lis3d/servlets/index.html";
RequestDispatcher dispatcher =
this.getServletContext().getRequestDispatcher(url);
if(dispatcher ==null)
System.out.println("Dispatcher == null");
else{
try{
dispatcher.include(req, res);
}catch (ServletException e){e.printStackTrace();}
}

There�s a reason why cannot be any static content like html
The dispatching uses the POST method from the HTTP protocol and html files can only be retrieved with GET method. If you wanna avoid a overhelm that might occur in your server because of the use of a dynamic content(like a login page) you can use the sendRedirect() method that redirects throught a GET to another page. i�m not sure now but i think its a method of the HttpSerlvetResponse class.
i hope i�ve helped

Invoking Tomcat 5 servlets through Apache

Hello,
I have Apache 2.0.45, Tomcat 5.0 and mod_jk1.2.2 running on Redhat 8.0.
I am trying to get Tomcat's jsp-examples and servlets-examples to run through Apache (http://localhost). They work as expected through Tomcat (http://localhost:8080).
I added the following to httpd.conf:
Alias /jsp-examples /jakarta-tomcat-5/webapps/jsp-examples
Alias /servlets-examples /jakarta-tomcat-5/webapps/servlets-examples
JkMount /jsp-examples/servlet/* Worker1
JkMount /jsp-examples/*.jsp Worker1
JkMount /servlets-examples/servlet/* Worker1
JkMount /servlets-examples/*.jsp Worker1
With the above included in Apache's config I am able to invoke the index.html for each of the above apps. However, when I click on any of the example links I get "Internal Server Error. The server encountered an internal error or misconfiguration and was unable to complete your request"
One of the links for the servlets-examples I am testing is:
http://localhost/servlets-examples/servlet/HelloWorldExample
And HelloWorldExample.class is in the /servlets-examples/WEB-INF/classes
directory.
With the above configuration shouldn't Apache route the request for the servlet through to Tomcat? What more do I need to add to either Apache's or Tomcat's conf files to get this to work? As I said, they work fine through Tomcat, so I don't think I need to tweak the web.xml(s)... or do I?
TIA
pwp

Here's a snippet of my configuration:
# mod_jk configuration file - Windows version
<IfModule !mod_jk.c>
LoadModule jk_module modules/mod_jk-1.3.27.dll
</IfModule>
JkWorkersFile "H:/tomcat-4/conf/workers.properties"
JkLogFile "H:/tomcat-4/logs/mod_jk.log"
JkLogLevel debug
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
JkRequestLogFormat "%w %V %T"
# begin: examples
Alias /examples "H:/tomcat-4/webapps/examples"

AllowOverride None
Order allow,deny
Deny from all
</Location>
<Location "/examples/META-INF">
AllowOverride None
Order allow,deny
Deny from all
</Location>
# end: examples
In Apache's http.conf add:
Include H:/tomcat-4/conf/jk/mod_jk.conf
Don't forget to restart both Tomcat and Apache
http://localhost/examples/jsp and http://localhost/examples/servlets should give you the std Tomcat JSP and Servlets examples

Hi,
Switching on or off a bpel is an admin job.
u can stop an application but not one bpel.
I doubt if there is any way to do it programatically.

ADF Bindings Servlet/Filter not invoking Faces Servlet

I'm getting ADF Faces and Facelets working properly with pages written in jspx format, but the Faces Servlet being mapped to jsf format.
The problem I'm getting is while displaying ADF Tables with data retrieved from the database using Toplink and bindings provided by ADF Databindings.
The following is the Web.xml mappings for Faces Servlet and ADF bindings filter:
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>resources</servlet-name>
<url-pattern>/adf/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.jsf</url-pattern>
</servlet-mapping>
<filter>
<filter-name>adfBindings</filter-name>
<filter-class>oracle.adf.model.servlet.ADFBindingFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>adfBindings</filter-name>
<url-pattern>*.jsp</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>adfBindings</filter-name>
<url-pattern>*.jspx</url-pattern>
</filter-mapping>
I'm getting the ADF tables displayed using ADF Bindings, if the faces servlet is mapped for jspx format;but, at the cost of losing Facelets...Facelets is not working with Faces Servlet mapped to jspx format(though written in jspx format, the faces servlet mappping has to be made for jsf format.On the other hand, if I use faces servlet mapping for jsf pages I'm getting Facelets working but ADF Databindings are not working ,(I guess) and hence ADF Faces Tables are not being displayed(I'm getting Access Denied message).
I even tried to change the ADF binding filter mappings
---- from ---- jsp &jspx---- to ----- jsp and jsf ----
But I got the same Access denied message.
I read a similar post on this forum by Mr.Ashish Kumar who said he is using java script and automatic form submission, to refresh the page and that gave him the table working.
as quoted in the post:
af:table displays Access Denied
Why should the page be refreshed at all. I Guess , the Faces Servlet is not being invoked by the ADF Bindings Filter/Servlet, and for this , I suppose , Mr.Ashish is using java script to provide the action required.
And one more thing which that Automatic Refreshing of page using JavaScript cannot do.
Suppose,
I need customised display, rather than just a Table or Form,like:
public String getEmp() {
BindingContainer bindings = getBindings();
OperationBinding operationBinding =
bindings.getOperationBinding("findAllEmp");
Object result = operationBinding.execute();
if (!operationBinding.getErrors().isEmpty()) {
return null;
List<Emp> res=(List<Emp>)result;
for(int i=0;i<res.size();i++)
Emp myrec=res.get(i);
System.out.println("Employee ["+myrec.getEname()+"], Salary ["+myrec.getSal()+"]");
return "";
where I do some customisation in the backing bean.
and I call that method binded to a button as below:
<af:commandButton
text="findAllEmp"
disabled="#{!bindings.findAllEmp.enabled}"
binding="#{backing_Success.commandButton1}"
id="commandButton1"
action="#{backing_Success.getEmp}"/>
What I'm getting is a disabled button.
Why doesn't ADF bindings servlet invoke the faces Servlet?
Can't we make ADF Bindings Servlet invoke Faces Servlet by configuring in the web.xml?
Can't we get ADF Bindings filter mapped to work with jsf pages?
Won't ADF Bindings work with jsf pages, will they work only with jspx pages?
ADF Team,
Please Help me.
Thanking you,
Samba

Hi! Frank,
Thankyou for your Reply.
Yes, Mr.Adam Winer has contributed that library, I guess.
But I already have that adf-facelets.jar in my lib folder ; and with out that the Facelets won't work with ADF faces , in the first place.
I'm getting Facelets working excellently with ADF Faces but I'm not getting ADF Bindings working with Faceletpages.
The thing is even in another application which does not have facelets in it, if we use mapping for jsf pages, ADF Bindings are not working.
I think the ADF bindings filter is configured some where to work with jspx pages only.Could you tell me where to change that entry to make ADF Bindings work with jsf extension?
Thanking you,
Samba.

Different ways to invoke a servlet from another servlets?

Hello,
I am a bit confused today. I was thinking about all the ways by which I can invoke a servlet from another servlets. I know it can be done by creating an instance of the 2nd servlet in the 1st one. Is there any other way? such as say.... RequestDispatcher perhaps?
Here is an example to illustrate my point. I have a login.jsp which submits to login.do. login.do search through database and first authenticate email and then the corresponding password. Now its time for displayGame.do. So here how do i do? if it was a displayGame.jsp then i could have used Redirection or Forward but when it is servlets? Can I still go for Redirection or Forward??
Thank you for reading this confused post. :-)

if it was a displayGame.jsp then i could have used Redirection or Forward but when it is servlets?Question: do you know what a JSP becomes when you first run it?
Answer: a servlet.
So yes, you can use a RequestDispatcher to forward/redirect to a servlet OR a JSP, whatever you like.

Invoking LiveCycle ES through WSDL via a form desinged in Designer ES

Now here is the situation exactly after tracing the process, let me describe first what does my simple process does.
Variables:
input1:int, Required, Input
output1:int, Output
it has 2 activities, the first activity is SetValue which is the start activity, it maps the value of the input into the output, simply it copies the input1 integer into the output1 integer
The second activity is Variable Logger, and it logs the values of the variables into a log.log file in the file system.
Now I tested this process using the invoke operation in the components view under the WorkflowDSC, after I invoke it, It shows me a number field to insert input1, I insert it and press ok, then it shows me output1, now I don't know why it shows me output1, but its ok, I leave it blank and press ok.
I check the log.log file on my file system and it is created and logging the same values for input1 and output1.
So apparently the process is working just fine.
Now on the other hand at the LiveCycle Designer ES, I create a blank XDP file (Interactive) then I create a Data Connection, choosing WSDL and the URL of the web service "http://localhost:8080/soap/services/InvokingLiveCycle?wsdl", and then comes the choose operation window, by default I see 5 operations for any service I create in the WorkBench which is "invoke", "invoke_Async", "invoke_Result", "invoke_Status" and "invoke_Dispose"
I choose "invoke" and there is invoke Request, invoke Response and invokeBtn, the invoke Request has the input1 Variable, and the invoke Response has the output1 Variable, and the invokeBtn is in the "execute" mode and pointing to my service and executing at the client, I insert all this in the form and test it in the Preview PDF tab.
Now this doesn't work at all, and the log file isn't created and of course the service isn't invoked in the 1st place, and this is my main problem.
It occurred to me to choose another operation and create a new Data Connection, I chose "invoke_Async", it has invoke_Async Request having the "input1" integer field same as "invoke" operation and it has also invoke_Async Response having the "invocationId" and invoke_AsyncBtn which is the same as the invokeBtn.
I insert these into the form and test it in the Preview PDF tab and I put a value in the input1 field then I press the invoke_AsyncBtn I get a response in the "invocationId" field which is "bc6b3f0fc0a85081000a998ebf903666" and surprisingly I find that the service created a log.log file and checking the value of output1 I find out that it is the same as I entered as input1, meaning the process worked and was successfully invoked, but of course I can't get to see the output1 field on my form, I don't know where is the response other than the "invocationId"
Now I really want to understand where is the problem.
Notes:
-By the way I am disabling all the services' security in the AdminUI --> Services -->Archive Administration --> Service Management.
-I tested another web service using the same technique which resides at "http://www.webservicex.net/CurrencyConvertor.asmx?wsdl" on the LiveCycle Designer Preview PDF tab and also in the Adobe Acrobat Professional, and its working both ways just fine.
P.S. I posted this to LiveCycle google group days ago, still didn't get an answer though.
Best Regards
Amr Marghany

Thanks Jasmine, I got a reply by Dave Venance suggesting I should change it to short-lived process,
it is working now after changing it to short-lived process and creating the Data Connection, I saw only 1 operation, which is "invoke" and I got to see the populated output1 in the form.
Well I thought of it a little, "What if the process is really long lived, and it is routed to an end user?"
then I was saying to myself "it makes sense, I can't get a response in the form except if the process is short-lived"
Now this small process was just for testing the whole thing, lets talk long-lived process a bit, I can invoke a long-lived process as I told you before from the "invoke_Async" operation, I will get over the fact that I don't know what is the "invoke", "invoke_Result" operations are for.
Lets just say I can invoke a long lived process from the operation "invoke_Async" and I can pass inputs to the service through the "invoke Async Request", This is going to be a bit long, I can deal with simple types in the "invoke_Async Request" like "int, string, float, etc..." but what if I want the user to submit the form as a whole to me in a variable like "document, xml with schema, xfaForm, etc..."?.
I can make a work around this, and I can use the setValue operation in the Workbench to map the simple input variables one by one to the corresponding path in the xfaForm variable like for example
Location: /process_data/exp_review/object/data/xdp/datasets/data/Expense/UserInfo/txtEmployeeName
Expression: /process_data/@txtEmployeeName
and on the other hand in the Designer I can bind each field on the form with its corresponding field from the Data Connection request.
This is the work around, but I want the user to submit a variable of type "xfaForm", like for example I want it to look like this
Location: /process_data/exp_review/object/data/xdp/datasets/data
Expression: /process_data/exp_report/object/data/xdp/datasets/data/Expense
Now when I tried to use this complex types as input variables in the Workbench, then I made a Data Connection to the exposed web service I saw many fields in the "request" that I don't understand, actually I didn't understand any of them.
For example when the input type was "document" the "request" had this fields
-"contentType", "attachementID", "binaryData", "remoteURL" and all of them are of type text fields.
Another example that I thought it might be the solution is submitting the data on the form as XML, so I created an XML variable on the Workbench called "xml" and I marked it as input and I set the XSD reference to my schema, now when I created the data connection on the Designer I found only 2 fields on the request inside a subform named "xml" which was "document" & "element" of type text fields!!
Another example, when the input type was "xfaForm" the "request" had this fields
-"data", "description", "name" and "templateURL" of type text fields and "renderOnce" of type checkBox
-it also has 3 subforms
1st subform: "dataAsDocument" containing "contentType", "attachementID", "binaryData", "remoteURL"
2nd subform: "renderServiceCall" containing 3 tables "inputParamterMappings", "outputParamateMappings" and "outputParamaterMappings"; each of the 3 tables has 1 row containing "key" and "value" of type text fields; the "renderServiceCall" table also has 2 text fields "operationName" and "serviceID"
3rd: "submitServiceCall" having the same tables and fields as "renderServiceCall"
How can I use such a variable of type xfaForm or xml, in the workbench I gave it the template url and the schema, but when I use the exposed web service in the Designer, I find out that the request has this fields I just mentioned.

How to -only- invoke a Servlet/JSP

Hi,
I would like to invoke a Servlet or JSP inside a standalone application WITHOUT opening a stream. When I use url.openConnection() or con.connect() the servlet/JSP is not executed, I must also do "ObjectInputStream o = new ObjectInputStream(con.getInputStream());" in order to get the servlet/jsp executed.
I just want to invoke the servlet/JSP, because I use the returned data for nothing.
Thanks

If you openConnection, you might also have to get the output stream from the servlet to make it work properly. (Otherwise, the server, or proxies in-between, might consider that the client has decided it doesn't want the page after all, and may stop requesting it.)
A cheap way to request a page but get less data back would be..
conn.setRequestMethod("HEAD");HEAD is exactly like GET, except it doesn't return the body (just the headers, hence the name.) Not entirely sure if it works on Java.
Failing that, you should be able to just open the input stream, and close it again straight away.

Problem in invoking a servlet from another PC

hi
i am trying to invoke a servlet running on apache tomcat 5.0.28 from another PC, my j2me wireless toolkit is on one PC and it runs a MIDlet that invokes a servlet on another PC, but am getting an exception connectionNotFound....
both the computers are on LAN, what do i do?
Need guidance

No, i think tomcat server is enough.. have u checked your servlet from browser?
I got the same error in black berry application and at that time i found that its due to servlet config in web.xml
Have u configured your servlet in web.xml?
One suggestion.. change your URL to www.google.com and then run your MIDlet.. it confermed that your midlet is OK
Http request is fine to send data from your WTK.

Method to get the file path that invoked a servlet

i have a html file that invokes a servlet.Within the servlet i want a method that gives me the path of the html file.Is this possible without using cookies.or is there any method that serves my purpose?

Hi,
after reading the last posts I think you should try what KPSeal said (althought I haven't tried it) or use my last suggestion :
on your HTML link (which will be handled by server) add an extra parameter (e.g. http://handle.xxx?page=mypage.HTML) and catch it inside the servlet code to know from what page it came.
nevertheless, about the getRequestURL() (and getRequestURI()) it's a method from the interface HttpServletRequest, in the package javax.servlet.http that comes in the Servlet API. (you can find the servlet API at http://java.sun.com/products/servlet/download.html), but I believe if you have a servlet you already should have inside it the request object.

Process + Servlet to invoke process + form + database

GetMortgageForm process
The following illustration shows the GetMortgageForm process (see Figure 2).
Figure 2. A LiveCycle ES process that returns an interactive form.
Note: This document does not describe how to create a process by using Adobe LiveCycle Workbench ES. (For information, see Workbench ES Help.)
The following table describes the steps in this diagram.
Operation Description
1 The user submits a custom identifier value and the operation to perform. In this situation, assume that the user is applying for a mortgage. The input parameters for this process are a string value that specifies the form name (named formName) and another string value that represents the custom identifier value (named custId).
Note: In the Java application logic located in the Java servlet, the formName and custId process variables are referenced.
2 The process uses the customer identifier value to perform a relational database look-up for additional customer information by using the JdbcService service's Execute SQL Statement operation. The custom identifier value acts as the primary key value.
3 Merges customer data into an XML data source that is used to prepopulate the form. (See "Prepopulating Dynamic Forms" in Programming with LiveCycle ES.)
4 The mortgage form is rendered with customer data located in some of the fields, such as the address field. This action is based on the Forms service's renderPDFForm operation.
The Java servlet receives the form (return value for the process) and writes the form to a client web browser. The name of the output parameter is RenderedForm. This parameter is a process variable and its data type is FormsResult.
Note: In the Java application logic located in the Java servlet that invokes this process, the RenderedForm process variable is referenced.
This interactive loan form is rendered by the GetMortgageForm process (see Figure 3).
Figure 3. An interactive form.
Note: This document describes how to use the Invocation API to invoke a LiveCycle ES process. It is recommended that you are familiar with the Invocation API before you follow along with this document. (See "Invoking LiveCycle ES Processes" in Programming with LiveCycle ES.)
Summary of steps
To create a Java servlet that invokes a LiveCycle ES process, perform the following steps:
1. Create a new web project.
2. Create Java application logic that represents the Java servlet.
3. Create the web page for the web application.
4. Package the web application to a WAR file.
5. Deploy the WAR file to the J2EE application server.
6. Test your web application.
Note: Some of these steps depend on the J2EE application on which LiveCycle ES is deployed. For example, the method you use to deploy a WAR file depends on the J2EE application server that you are using. This document assumes that LiveCycle ES is deployed on JBoss®.
Creating a web project
The first step to create a Java servlet that can invoke a LiveCycle ES process is to create a new web project. The Java IDE that this document is based on is Eclipse 3.3. Using the Eclipse IDE, create a web project and add the required JAR files to your project. Finally, add an HTML page named index.html and a Java servlet to your project.
The following list specifies the JAR files that you must add to your web project:
adobe-forms-client.jar
adobe-livecycle-client.jar
adobe-usermanager-client.jar
adobe-utilities.jar
For the location of these JAR files, see "Including LiveCycle ES Java library files" in Programming with LiveCycle ES.
Note: The adobe-forms-client.jar file is required because the process returns a FormsResult object, which is defined in this JAR file.
To create a web project:
1. Start Eclipse and click File > New Project.
2. In the New Project dialog box, select Web > Dynamic Web Project.
3. Type InvokeMortgageProcess for the name of your project and then click Finish.
To add required JAR files to your project:
1. From the Project

How to invoke a servlet from an application-URGENT

Hi,
          My requirement is as follows :
          I have to invoke a servlet from a client application. I am using
          java.net.URL and java.netURLConnection classes to
          open a connection and invoke the servlet.
          I am using WebLogic5.1
          my code snippet is as follows :
          URL url = new URL("http://localhost:7001/urlservlet");
          URLConnection connection = url.openConnection();
          connection.setRequestMethod("GET");
          connection.setDoOutput(true);
          connection.setDoInput(true);
          PrintStream outStream = new PrintStream( connection.getOutputStream() );
          outStream.print("message=hai");
          outStream.flush();
          outStream.close();
          When I execute the application, Webloigc server console is displaying the
          following line.
          <Listen Thread> Adding Address : <machine name><ip address>
          But the service method of servlet is not getting invoked at all.

How to invoke a servlet from MDB

Hi,
Can someone please tell me how to invoke a servlet from MDB. Actually I want to have a MDB that will invoke a servlet that takes arround ~3 minutes to process and send the response back to MDB. Any small code snippet on invoking a servlet.
Thanks

nope. this is probably a bad design.
but here's a hint: whenever you have a question like this, start browsing the javadocs. chances are there's a class that might help you.
i'd recommend that you look at this:
http://java.sun.com/javase/6/docs/api/java/net/HttpURLConnection.html
