Error in Tomcat with Servlet
Hi,
I made a webapplication in JBuilder. When I run the project it runs just fine, even when I type the URL http://localhost:8080/webshop/file.shtml in explorer. Very simple.
I installed the project war file in tomcat with the manager and tomcat made a webshop dir in web-app. This dir contains all the files needed for Tomcat to run a web-app
I configured the web.xml, it looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
<servlet>
<servlet-name>dbservlet</servlet-name>
<servlet-class>webwinkel.DBServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>dbservlet</servlet-name>
<url-pattern>/dbservlet</url-pattern>
</servlet-mapping>
</web-app>
But the web-app doens't run online. When I try to reach the servlet I get a 404. Tomcat can't find the servlet. Am I forgetting something here, if it runs local in JBuilder shouldn't it just as easy run on a webserver?
please help I'm desperate
Susan
looks like you should be pointing to the following url to get to your servlet:
http ://localhost:8080/webshop/dbservlet
Is this what you or your form is pointing to? Are you able to get to /file.shtml but not the servlet?

Some problems with servlet.jar and tomcat 4.1.27
Hello everybody,
I used to work with tomcat 3.3.1 and i've decided to use tomcat 4.1.27 now. The manual explains that we have to change de version of servlet.jar, it's done with servlet-2.3.jar but on tomcat starting i have this message:
jar not loaded. See servlet spec [...]. Offending class: javax/servlet/Servlet.class
what can i do, i've red all de documentation and i think all versions a OK??
thanks per advance
antoineI am running Tomcat 4.1.18, so your configuration may be slightly different. I found the Servlet.class file you are missing residing in the Tomcat/common/lib directory in the Servlet.jar file. Check your path and also make sure your Servlet.jar file contains the missing class.

[Help] To prevent timeout error of browser in clinet with servlet in server
Hi all,
If a browser (for example, Internet Explorer) do not get any response from a server for more than sometime (in case of IE, default is 5 min), it will stop waiting and return some timeout error message.
But I have a servlet, which has a really long-time(at least 10 min) job to do before it could send a response to the browser. So, before the browser in client can get the result, it stops waiting.
I know I can change the time-out setting of browser in client machines, but there are hundred of thousands.
So, what I am asking is if it is possible to do it with servlet in server, and how?
(for example, send something to the client every few minutes, but I do not know how to do it .)
thanks a lot!What you would have to do is set up some sort of 'Buffer' servlet.
It starts the job in the background, and then returns a page saying job started - client does not time out.
You would have to start it in a seperate process - probably a new Thread.
The client would then have to send back requests asking - is it finished yet?
While the job is not finished the buffer servlet returns a "not yet" message.
On completion, the job can be sent back to the client.
Couple of pointers:
It may be easier to have the background process generate the result to file - then your buffer servlet can just pick up the file when it is completed.
To get your page to refresh multiple times, you can use javascript: window.setTimeout("[reload page]");
Good luck,

Error : Apache tomcat 5.5 not starting with windows server 2003 32 bits
I can not start Tomcat 5.5 installed and deployed from the Business Objects BI Edge 3.1.

I tried to start tomcat from the control panel -> administrative tools -> services. But also not start.
You receive the following message: Windows could start in Apache Tomcat 5.5.20 on the local computer.

Error in struts with collection classes
Hi All,
I have tried to list all the employee through dabase search i have created with strus logic tag in search.jsp page
as following
<bean:size id="size" name="searchForm" property="results"/>
<logic:equal name="size" value="0">
<center><font color="red"><b>No Employees Found</b></font></center>
</logic:equal>
<logic:greaterThan name="size" value="0">
<table border="1">
<tr>
<th>Name</th>
<th>Social Security Number</th>
</tr>
<logic:iterate id="result" name="searchForm" property="results">
<tr><td><bean:write name="result" property="name"/></td>
<td><bean:write name="result" property="ssNum"/></td>
</tr>
</logic:iterate>
</table>
</logic:greaterThan>
</logic:present>
2. The following class shows ActionServlet as SearchAction.java class
public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request,HttpServletResponse response)
throws Exception
EmployeeSearchService service = new EmployeeSearchService();
List results=new ArrayList();;
SearchForm searchForm = (SearchForm) form;
// Perform employee search based on what criteria was entered.
String name = searchForm.getName();
if (name != null && name.trim().length() > 0)
results = service.searchByName(name);
/* else {
results = service.searchBySsNum(searchForm.getSsNum().trim());
// Place search results in SearchForm for access by JSP.
searchForm.setResults(results);
// Forward control to this Action's input page.
return mapping.getInputForward();
3. The following class created for search the employee as EmployeeSearchService.java
Note: This file will implement EmployeeDB.java for database connections and also the values are return using Employee.java as for get and set method of name and id..
EmployeeSearchService.java
public List searchByName(String name)
// List returnList=new ArrayList();
List results=new ArrayList();
EmployeeDB em=new EmployeeDB();
results=em.searchName(name);
ListIterator langIt=results.listIterator();
while(langIt.hasNext())
Employee emp=(Employee) langIt.next();
String name2 = emp.getName();
String SSNo=emp.getSsNum();
System.out.println("Emp Name:"+ name2);
results.add(name2);
results.add(SSNo);
4. EmployeeDB.java contain the following code..
public class EmployeeDB extends AbstractDAO
public List searchName(String name1)
{ //External Interface
List resultList = new ArrayList();
ResultSet resultSet = null;
Statement aStmt2 = null;
String url="jdbc:odbc:test";
String uname="root";
String pwd="root";
String name="";
try {
Connection con=getConnection();
aStmt2 = con.createStatement();
String query2 = "SELECT SSNO,NAME FROM EMPLOYEE WHERE NAME ='"+ name1 +"'";
cat.debug(query2);
resultSet = aStmt2.executeQuery(query2);
while(resultSet.next()){
Employee tvo = new Employee();
name = resultSet.getString("NAME");
String SsNum1 = resultSet.getString("SSNO");
tvo.setName(name);
tvo.setSsNum(SsNum1);
resultList.add(tvo);
catch (Exception e) {
System.out.println( e);
e.printStackTrace();
return resultList;
My Problem is all the classes are compiled and excute and validation work fine but while the name of employee entered that if name is available in DB table which reply the following error message as,
javax.servlet.ServletException

Plz reply how to solve send correct code to send data to values of iterate bean.... which line of code i need to modify...
Thanks.So here is what you are doing:
ArrayList results = //get employees from database
ListIterator langIt = results.listIterator();
while (langIt.hasNext()) {
Employee emp = langIt.next();
String name2 = emp.getName();
String SSNo = emp.getSSNum();
results.add(name2);
results.add(SSNo);
}So you get a list or Employee objects, then you get an iterator over the list. For each Employee in the list you add the name and SSNo as Strings back to the same list. From the API for ConcurrentModificationException the exception can be thrown when you modify a collection while iterating over the collection - which is precisely what you are doing.
The ListIterator interface allows you to modify the list through its own methods. Try using:
langIt.add(name2);
langIt.add(SSNo);instead.
Why are you taking the name and SSNo out of the Employee object and placing them back in the same List anyway? That makes no sense to me. -
Save byte array (image) to file with servlet
Good day.
I should must to save a png image to file.
I have a byte array of the image.
This work is in a servlet.
How can I do it?
Best regards.
Stefano ErraniGood day.
I have a byte[] and then I have used
FileOutputStream fos = new FileOutputStream(getServletContext().getRealPath("/public_html/mcfoto/foto1.png"));
fos.write(bt, 0, bt.length); // byte[] bt
fos.close();
This on my web server that has public_html as root web directory.
The server is in multi domain.
In this mode I have an error.
Then I have tryied to use
FileOutputStream fos = new FileOutputStream("http://www.stefanoerrani.it/mcfoto/foto1.png");
and
FileOutputStream fos = new FileOutputStream(getServletContext().getRealPath("http://www.stefanoerrani.it/mcfoto/foto1.png"));
In both ways I have obtained an error.
At last I have tryied in my localhost (local machine) using
FileOutputStream fos = new FileOutputStream(getServletContext().getRealPath("/mcfoto/foto1.png"));
All run correclty.
The Application Server is Tomcat with Apache HTTP Server.
The first server (of www.stefanoerrani.it) has Linux as OS.
My local server has Windows as OS.
I should want, if it's possible, an help.
Best regards.

Im using tomcat 4.06 and i have some problems with servlets and forwarding:
This is my servlet:
import java.io.PrintWriter;

String email = request.getParameter("tenant");
//insert new tenant into database.
System.out.println("Redirigiendo");
ServletContext sc = getServletConfig().getServletContext();
RequestDispatcher rdNext = sc.getRequestDispatcher("/tenantForm.html");
rdNext.forward(request, response);
System.out.println("Redirigido");
I get this error:

Errors in Tomcat startup window
Hi!
I'm using Tomcat 4.1.24 and have been testing out a simple shopping cart application that uses 3 servlets called Selection, Weight and Checkout. (This is an appplication of mine that works fine under the JSWDK.) Before I added the files for the shopping cart application, my web.xml file (in ROOT\WEB-INF) referred to a single existing servlet called FirstServlet:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
<servlet>
<servlet-name>FirstServlet</servlet-name>
<servlet-class>FirstServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>FirstServlet</servlet-name>
<url-pattern>/servlet/FirstServlet</url-pattern>
</servlet-mapping>
</web-app>
In this form, there are no error messages when starting up the Tomcat server.
I then modified the web.xml file to refer to the additional servlets so:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
<servlet>
<servlet-name>FirstServlet</servlet-name>
<servlet-class>FirstServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>FirstServlet</servlet-name>
<url-pattern>/servlet/FirstServlet</url-pattern>
</servlet-mapping>
<servlet>
<servlet-name>Selection</servlet-name>
<servlet-class>Selection</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Selection</servlet-name>
<url-pattern>/servlet/Selection</url-pattern>
</servlet-mapping>
<servlet>
<servlet-name>Weight</servlet-name>
<servlet-class>Weight</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Weight</servlet-name>
<url-pattern>/servlet/Weight</url-pattern>
</servlet-mapping>
<servlet>
<servlet-name>Checkout</servlet-name>
<servlet-class>Checkout</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Checkout</servlet-name>
<url-pattern>/servlet/Checkout</url-pattern>
</servlet-mapping>
</web-app>
Now, when I start up the Tomcat server, I get a series of error lines commencing with the following:
27-Jun-2003 10:13:03 org.apache.commons.digester.Digester error
SEVERE: Parse Error at line 49 column 11: The content of element type
"web-app" must match "(icon?,display-name?,description?,distributable?,
context-param*,filter*,filter-mapping*,listener*,servlet*,servlet-mapping*,session-config?,mime-mapping*,welcome-file-list?,error-page*,
taglib*,resource-env-ref*,resource-ref*,security-constraint*,login-config?,security-role*,env-entry*,ejb-ref*,ejb-local-ref*)".
at org.apache.xerces.util.ErrorHandlerWrapper.createSAXParseException(Unknown source)
Line 49 column 11 is the character position immediately following my terminating </web-app> tag.
Evidently, I need to include some further tags between those relating to consecutive servlets above in order to avoid these error messages. Does anybody know what is required here??
As it happens, Tomcat starts up successfully after producing these error messages and there is no problem with the running of the shopping cart application (which is the main thing, of course!), but I really would like to get rid of the error messages.
Any help would be most appreciated. Thanks in anticipation.
JanPlease don't bother trying to answer my email. I've just realised what the simple solution is -- I must have all the <servlet> tags before all the <servlet-mapping> tags.
Cheers.

Error: pool exhausted with 100 threads
hi,
I was wondering if anybody can provide me some
leads on how to deal with this problem... I have a
servlet that queries a database and churns
out (in response) a data populated html, however
after some time and several hits on the servlet, I
get the error that "ThreadPool: pool exhausted with
100 threads".
I'm not so sure if this is a webserver (I use tomcat)
or servlet problem, would certainly appreciate if
anybody can provide some help. tia!
jsonYou are experiencing a problem with the Tomcat Configuration likely. Look in the documentation and read about the configuration, and find where to increase the maximum number of clients at a time. If you are running a low-load server (just you?) then make sure that your servlets aren't entering an infinite loop somewhere and never exiting. Also, make sure you close all your printwriters or streaming outputs/inputs, because that can sometimes keep a thread alive longer than it should.
Good luck,
GN -
Help needed. Problem with servlet.
Hello ppl. Ok. I've never really needed to implement servlets in my projects before but I experimented by writing a simple helloworld servlet. It compiled successfully and I tested it in the examples servlet dir and it worked. To test it in the ROOT dir, I placed the servlet in the ROOT/WEB-INF/classes folder and edited the web.xml file with:
<servlet>
<servlet-name>HelloWorldExample</servlet-name>
<servlet-class>HelloWorldExample</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HelloWorldExample</servlet-name>
<url-pattern>servlet/*</url-pattern>
</servlet-mapping>
When I try and execute the servlet by using this URL: localhost:8080/servlet/helloworld I get an internal server error and the server crashes. I removed the entry from the web.xml file and Tomcat started up again. What went wrong? Can someone enlighten me in how to get my test servlet working becuase i may use them in the future. Thanks.Nope, Still didnt work. As soon as I put in:
<servlet>
<servlet-name>HelloWorldExample</servlet-name>
<servlet-class>HelloWorldExample</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HelloWorldExample</servlet-name>
<url-pattern>servlet/HelloWorldExample</url-pattern>
</servlet-mapping>
Tomcat went offline!
I have another entry which is:
<servlet>
<servlet-name>org.apache.jsp.index_jsp</servlet-name>
<servlet-class>org.apache.jsp.index_jsp</servlet-clas
>
</servlet>
<servlet-mapping>
<servlet-name>org.apache.jsp.index_jsp</servlet-name>
<url-pattern>/index.jsp</url-pattern>
</servlet-mapping>
Do you think they may be conflicting? Thanks.Tomcat going offline is quite weird. However,
<url-pattern>/index.jsp</url-pattern>
this is perfectly valid. Lemme ask you this: did u come up with this stuff on your own or was it generated for you by the container? It looks like it was generated upon compilation of the jsp. If that is the case it should cause any conflicts. However now if you want to invoke the servlet/jsp you must use a URL like:
http://localhost:<PORT_NO>/index.jsp

Error in WebDynpro with WebServices
Hi all,
Im getting some errors using applications deployed in WEB AS SP9 that runs as a WebDynpro IView in EP.
Running the application as standalone (out of EP) this works fine.
NetWeaver Developer Studio 2.0.9
WebDynpro application using WebServices that access Oracle 8i database in the follow sequence:
WebServices -> Session Bean stateless -> Entity Bean CMP (manage connections; generate sql code, etc.)
In WebDynpro application we import WebService Model by the follow sequence:
New Model - Import Web Service Model - Local Server for WSDL Source - <WebService deployed>
In each WebServices we have created these methods:
findByID(ID);
getAll();
insert(parameters);
remove(ID);
update(parameters);
We guess that the error is generated in Entity Bean because all WebServices generate these errors.

Error in communicating with DCR Server.
DCR Server may be down. Please start the DCR Server and then refresh the page.
I am using windows 2008 standard server RC1 SP1, and CiscoWorks LMS 4.0.
I had applied all of patches includes.
The DCRserver is running. ( I did restart it)You're using Windows 2008 RC1 (a release candidate version)? LMS is only supported on the final shipping version of Windows 2008, and not yet on R2.
If you're running on the final version of 2008 server, post the output of the pdshow command as well as the dcr.log, DCRServer.log, NMSROOT/MDC/tomcat/logs/stdout.log and stderr.log. -
