Servlet Reloading Problem!
JSP + Bean is OK!
But, Servlet + Bean occur a reloading problem.(Reloading does not happen)
For example,
1) TestClass.java (Bean)
public class TestClass {
private String txt;
public TestClass() {
txt = "Test!!"; ---(1)
public String getTxt() {
return txt;
2) Test.java (Servlet)
public class Test extends HttpServlet {
public void service(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException {
TestClass testClass = new TestClass();
PrintWriter out = res.getWriter();
out.println(testClass.getTxt());
In above examples, though I change txt String(number (1)) Bean reloading does not occur. So old txt String shows.
In Tomcat, such problem does not happen.
Is this a problem of OC4J?
Thanks.

Well, only servlets are supposed to be reloaded, not their dependent classes.
If you are using Tomcat 4.x, then there might be an explanation. It seems that Tomcat 4.x will simply reload the entire web app context if it detects that a servlet (not a JSP!) has changed. Just define a servlet context listener to see that.

Servlet reloading doesn't work
Running WL 5.1 SP6 and can't get servlet reloading to work. Have the
necessary lines in weblogic.properties:
weblogic.httpd.servlet.classpath=<my classpath>
weblogic.httpd.servlet.reloadCheckSecs=1
The servlets are in a web app so I have the web app's WEB-INF/classes, where
the servlets reside, in weblogic.httpd.servlet.classpath.
Possibly this is a problem only with web apps? Anyone else run into this?
Thanks.
From my understanding, putting the servlet classes in the WEB-INF/classes
directory eliminates the need to put them into any classpath (servlet, weblogic,
or otherwise). Put them back into the WEB-INF /classes directory and make sure
that this directory is not in the weblogic or servlet classpath.
Hope this helps,
Robert

Hi,
I am just starting to learn servlets and I got problem in compiling them. I got compilation error in
import javax.servlet.*;statement. Seems that the compiler cannot find the servlet package. I got J2EE 1.4 beta installed on my machine but there is no servlet.jar package. I am using J2SDK 1.4.1_02, J2EE 1.4 beta and Tomcat 4.1.24.
Can anyone help me with my servlet compilation problem?
Thanks in advance!
Joshservlet.jar is here :
<tomcatdir>\common\lib
add it to your compiler classpath -
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class Deblink extends HttpServlet {
public void doGet(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
String contentType = req.getContentType(); // get the incoming type
if (contentType == null) return; // nothing incoming, nothing to do
res.setContentType(contentType); // set outgoing type to be incoming type
PrintWriter out = res.getWriter();
BufferedReader in = req.getReader();
String line = null;
while ((line = in.readLine()) != null) {
line = replace(line, "<BLINK>", "");
line = replace(line, "</BLINK>", "");
out.println(line);
public void doPost(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
doGet(req, res);
private String replace(String line, String oldString, String newString) {
int index = 0;
while ((index = line.indexOf(oldString, index)) >= 0) {
// Replace the old string with the new string (inefficiently)
line = line.substring(0, index) +
newString +
line.substring(index + oldString.length());
index += newString.length();
return line;
What is pre request fo above code to work.
I had tried this many time but it is not working, what will be calling servlet look likeAnd can you explain why your title is "Servlet chaining problem"?

How to make servlets reloadable in iplanet web server in solaris??
hi all,
does anyone know how to make servlets reloadable in iplanet ??? Thanks for helpHi there,
I think your question is about "Dynamic Class Reloading", also named as Hot deployment. and the following lines may be helpful.
iAS 6.0 SP3 and later version supports new hot deployment features through dynamic class
reloading of EJBs.By default, dynamic servlet, EJB and registered JSP reloading is disabled in iPlanet Application Server.
To enable dynamic reloading of servlets, EJBs and registered JSPs, perform the following steps:
1.Start iPlanet Registry Editor, kregedit, and modify the Disable value under the Versioning key:
SOFTWARE/iPlanet/Application Server/6.0/CCS0/SYSTEM_JAVA/Versioning
2.Set the Disable value to 0 (By default, the Disable value is set to 1)
3.Restart iPlanet Application Server to enable the change
To hot deploy your application, simply compile and replace the file in the appropriate directory or, use iasdeploy to redeploy
applications.
I recommand you to check out the iAS's release notes (http://docs.iplanet.com/docs/manuals/ias/60/sp3/rn_sp3.html#20766) for more infomation.
Good luck

I need to disable servlet reload(WLS 7 SP4) for performance reason. I set the
servlet-reload-check-secs to -1 in the container-descriptor of the web.xml of
my war file. However when I deploy my war file, from the admin console the "Reload
Period" is set to 1. Is there a way to make the deployment set the default "Reload
Period" to -1 during deployment? I hate to deploy, change "Reload Period" from
console, shutdown server, them restart server. Thanks.

Servlet reloading not working with WLS 5.1 sp8
I downloaded and installed WLS 5.1's sp8 to fix the "java.net.SocketException: Connection aborted by peer: socket write error"
problem. Although that problem is fixed, I have found that, however, the servlet (automatic) reloading does not
work anymore. If I remove the sp8 from my Java system classpath and WL classpath (i.e. not using sp8), then
the servler reloading works fine.
Does anybody experience similar problem or have I forgot to do something?
WLS properties/env vars setting:
- weblogic.httpd.servlet.reloadCheckSecs=0
- WEBLOGIC_CLASSPATH=%WEBLOGIC_HOME%\lib\weblogic510sp8.jar;...
- JAVA_CLASSPATH=%WEBLOGIC_HOME%\lib\weblogic510sp8boot.jar;...
Thanks in advance for any help.
I've experienced the same problem with both sp6 and sp8. In both cases I performed several test, including
- varied the value of weblogic.httpd.servlet.reloadCheckSecs
- changes to the package depth the servlet belonged to
- changes to the string length of the package names the servlet belonged to
At best, the servlet would reload sometimes. I've moved back to sp5 and the problem has subsided.
Note: I did not try registering the servlet to see how that would effect the dynamic reloading.
Hope this helps

Hello, everyone!
The problem that I have might sound ridiculous but I am kind of desperate because I can't make head nor tail of it.
I am using Tomcat 4.0 and JDK1.3.1_01 and the problem that I am facing is the following: I have an application called "prima" that I've placed in the "webapps" directory of the Tomcat home. I've created the whole directory structure required - that is:
/prima/Web_inf/classes
/prima/Web_inf/lib
as well as the
/prima/Web_inf/web.xml configuration file
I've placed the following string in the /conf/server.xml
configuration file:
<Context path="/prima" docBase="prima"
debug="0" reloadable="true" />
I wrote the simplest servlet possible - the "HelloWorld" servlet which I called TryServlet. Here goes the code:
import java.io.*;
import java.util.*;
import java.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class TryServlet extends HttpServlet {
public void doGet (HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<html>" +
"<head><title>Hello World</title></head>");
out.println("Hello, World!");
out.println("</body></html>");
out.close();
I've placed this in the /prima/Web-inf/classes directory and compiled it.
I've edited the web.xml file like this:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"
"http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">
<web-app>
<servlet>
<servlet-name>tryserv</servlet-name>
<servlet-class>TryServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>tryserv</servlet-name>
<url-pattern>/serv</url-pattern>
</servlet-mapping>
</web-app>
Then I've written in the browser the following URL:
http://localhost:8080/prima/serv
http://localhost:8080/prima/servlet/serv
and in neither cases does it work. I get the HTTP 404 - File not found exception.
I had encountered a similar problem when I tried to use a bean from a JSP page.
It looks like the /prima/Web-inf/classes directory cannot be seen.
I hope someone will have a solution for my problem. Thank you in advance for any suggestion!
Best regards!Tomcat is case sensitive. Use WEB-INF

Tomcat Servlet Security Problem? : Start Excel with NJAWIN - COMObjects
I get an exception when I start my programm as servlet , as application it works just fine (when I start it as Servlet in the internal Tomcat from JBuilder it also works fine).
Application app = new Application(Application.progID); // interfaces built with java2com for Excel
com.develop.jawin.COMException: 8000ffff: CoCreateInstance for "{024500-00-0000-c000-000000000046}" failed

at com.develop.jawin.win32.Ole32.GetFromProgID(Unknown Source)
at com.develop.jawin.DispatchPtr.<init>(Unknown Source)
at excel2pdf.Excel._Application.<init>(_Application.java:31)
Actually Excel is started but as SYSTEM and not as my Username. Perhaps there's a problem with the security policy, I already gave all rights to catalina for my whole projekt( each directory of it). Have smb already had this problem? Any Ideas?Thanks for answering
In my case I think I cannot use POI because I need Excel
and a Virtual Printer , so I can convert excel files with exactly the same
format to PDF. POI is suppose better idea for creating or manipulating
OpenOffice files (they are working together with OO on file formats),
and unfortunately OpenOffice doesnt work fine with charts (I already had
this solution, openoffice-server and Uno ).
It must be smth with Tomcat-Configuration or security, because my
programm is working with the internal tomcat-server of JBuilder, and
as application too. In both cases Excel is started with my username and
not SYSTEM (my tomcat server is started as service, perhaps thats why
by starting excel from my servlet Excel is by user - SYSTEM). -
Applet-Servlet Communication problem EOFException
Hi! i´ve been searching and searching through forums because it seems this problem is very common, but none of the solutions i´ve seen so far suits me, so i´m here looking for some help because i´ve been stuck one week with this. First of all sorry if my english isn´t the best... i´m a bit rusty...
Well, i had some code that worked perfectly, but i needed to perform some changes because i needed the servlet to send more info to the applet, and here started the problems, when i made the changes it started to throw EOFException when i was trying to read the InputStream, and furthermore when i came back to the original code it started to throw the exception in the same place too
So here i am... don´t know what to do now and i entrust to you to give me some tips.
Here comes some code. This is the original code, the one that runned but it doesn´t run right now

}i´ve been running some test in another computer, and this code simply works, but it doesn´t work in the machine i usually work.
Maybe someway the stream get corrupt? the info i´ve been trying to send and started throwing the exception may still be in the stream? I don´t know what to think right now.
Hope someone has any idea, thankyou.I dont see the problem. However, I suggest you change this;
System.out.println("Error en la trasmision de datos"); t
to e.printStackTrace() to see what it is doing when it stops working.
I also suggest peppering your code with System.out.println() statements to see what it is doing just before stopping.
Also, try your code with a brand new file with only a few characters in it. If it works, add to it some of your originial file content until it stops working. This way, you can determine if its the file size that is causing the crash or something in the file content. If all else fails, study java I/O and try some other way to read/write the file. You can also try a different browser. If it works, its the browser. Still having problems? Create a new project with a simple applet and file read/write program and get that working. That way, all the other stuff in your original project isn't in the way. -
Servlet mapping problem in Resin, very weird!
ENV: resin 2.1.6 on windows 2000
1, I copied all the files and folders in $resin/doc/java_tut to $resin/webapps
2, I did a little change to $resin/conf/resin.conf
In the old resin.conf, there is a lot about the '/' webapp.
<web-app id='/'>
<classpath id='WEB-INF/classes'
source='WEB-INF/classes'
compile='true'/>
</web-app>
I replaced it just with
<web-app id='/'/>
3, I tested the 'java_tut' webapp
http://localhost:8080/java_tut/servlet/example.servlet.basic.MappingServlet
works well.
http://localhost:8080/java_tut/exact
works well, too.
4, Then I tested the '/' webapp
http://localhost:8080/servlet/example.servlet.basic.MappingServlet
works well.
but
http://localhost:8080/java_tut/exact
returns error code 404
what's the problem?don't you need to get rid of the java_tut bit?

How to send Oracle rowid to servlet? | Problem with national characters.
There is same possibility how to send rowid to servlet?
I have now definition like this:
<af:image source="/imageservlet?Par1=#{bindings.Col1.inputValue}"/>
But If column contents national characters, servlet methods obtained changed these characters.
My idea is to use not primary key for row, but use oracle rowid. It is simply possible?
Use something like this:
<af:image source="/imageservlet?Rowid=#{bindings.Rowid}"/
Or Do you have ideas how to solve problem with national characters ?
Thanks
FiLHi,
Although your workaround works.
I think this is a simple encoding problem.
I simply need to make sure all parameters and pages are encoded with a char set which contains the national characters you mentioned.
This is a bit dependent on the exact technology your using, but most can be done via the web.xml:
<jsp-config>
<jsp-property-group>
<url-pattern>*.jsp</url-pattern>
<page-encoding>UTF-8</page-encoding>
</jsp-property-group>
</jsp-config> This forces all JSP pages to be encoded in UTF-8
Adding the following parameter sometimes helps as well, although I think this one is a bit dated:
You said your using a servlet so your servlet needs a similar block for its pattern
<context-param>
<param-name>PARAMETER_ENCODING</param-name>
<param-value>UTF-8</param-value>
</context-param>If you want to be 100% sure the encoding is set right make sure thepages contain:
<%@ page contentType="text/html;charset=utf-8"%>Or depending on your view technology the syntax can be a bit different
