Problem of DNS in Java Web Server

Hi!
I have problem, I have written servlets but when I run them using Java Web Server Exception arrises that DNS could not resolved however when I run the same code as application it gives correct results without exception. I am using the Java Web Server 2.0

why r u using JWS? Sun has declared End of Life of JWS.
why don't you use any other app server (like Tomcat ...etc)

Do i need a network card to install and run a local java web server

Friends,
Do i need a network card in my computer to install and run a local Java Web Server or any Web Server.

network cards are only for connecting equipment together... you can set up a webserver without any more equipment than you have already! Indeed Tomcat... BUT you would be better off with apache for production stuff. It depends what you need to serve... if its mainly static pages (i guess it probably isn't) then apache will be enough by itself; but if you need to serve dynamic pages (JSP, Servlet blah blah) then you will need tomcat. Tomcat has it's own webserver and its perfectly ok for testing or low-load stuff, but you can integrate with Apache (a moderately compex task, but do-able, see tomcat-user forum off of apache site) for greater stability, and you don't have to show the port in the URL... Don't set up a webserver on any pc that contains stuff you don't want hacked into... it becomes very succeptible when the service is up...

Oracle.xml.xsql.XSQLServlet in Java Web Server 2.0

Does anyone know how to add the oracle.xml.xsql.XSQLServlet in the Java Web Srever 2.0? When running the helloworld.xsql I am now getting the following error message.

I have the alias *.xsql set to map to the servlet named oracle.xml.xsql.XSQLServlet under the Servlet Aliases section, but I'm not sure how to add the servlet under the Servlet section, as I'm guessing that this is the problem I'm now experiencing. I tried adding oracle.xml.xsql.XSQLServlet as both the servlet name and class, but this is not working.
Any help would be greatly appreciated. Thanks!

Rani,
The following is part of a message that was posted back on Nov. 7 of '99 from Steve Muench. I just followed this exactly with the Java Web Server 1.0.1 and it worked fine (including adding the classpath settings and xsql servlet mappings as it says below). Thanks,Dan
Here's the steps I just followed to run all the XSQL Demos under JSWDK 1.0.1
(1) Downloaded jswdk1_0_1-win.zip from Sun
(2) Installed in D:\jswdk-1.0.1
(3) Edited "startserver.bat" to add the
classpath entries needed by XSQL Servlet:
set CLASSPATH=%CLASSPATH%;d:\xsql\lib
set CLASSPATH=%CLASSPATH%;d:\xsql\lib\classes111.zip
set CLASSPATH=%CLASSPATH%;d:\xsql\lib\oraclexsql.jar
set CLASSPATH=%CLASSPATH%;d:\xsql\lib\oraclexmlsql.jar
set CLASSPATH=%CLASSPATH%;d:\xsql\lib\xmlparserv2.jar
(4)Edited d:/jswdk-1.0.1/webpages/WEB-INF/servlets.properties and added the line:
xsql.code=oracle.xml.xsql.XSQLServlet
(5) Edited d:/jswdk-1.0.1/webpages/WEB-INF/mappings.properties
and added the line:
.xsql=xsql
(6) Copied D:\xsql\demo to D:/jswdk-1.0.1/webpages/xsql/demo
(7) Started the Webserver with "startserver.bat"
(8) Browsed http://localhost:8080/xsql/demo/index.html
(9) Exercised all the demos.
Hope this helps.

Putting a helloword.java code to run on Sun Java Web Server

Hello,
Given helloworld.jsp:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class HelloWorld extends HttpServlet {
public void doGet(HttpServletRequest req, HttpServletResponse res)
               throws ServletException, IOException {
     res.setContentType("text/html");
     PrintWriter out = res.getWriter();
     out.println("<HTML>");
     out.println("<HEAD><TITLE>Hello World</TITLE></HEAD>");
     out.println("<BODY>");
     out.println("<H1>Hello World</H1>");
     out.println("Today is: " + (new java.util.Date().toString()) );
     out.println("</BODY></HTML>");
} // doGet
} // HelloWorld
How can I put this code to run on Sun Java System Web Server, how to compile this ? what and how to put in the webserver document and how to access it ?
Thanks for verbose and basic information about this, appreciated...

What you wrote is not a JSP. It is a Java Servlet.
You need to compile it. That creates HelloWorld.class.
Create a directory say hello. You need to create a directory structure as mentioned below.
hello|
WEB-INF|
web.xml
classes|
HelloWorld.class
You need to package it in a war (web archive) file.
%cd hello
%jar cvf hello.war .
Then deploy this war file using admin GUI or wadm CLI.
I would suggest using Netbeans IDE to create the web application.
To deploy the war file on SJS web server 7 update 2, see my blog at
http://blogs.sun.com/kmeduri/entry/how_to_deploy_a_war

Problem running Forms on Oracle Web Server 3.0

I have implemented Developer/2000 forms on Oracle Web Server 3.0 (Non Cartridge Implemetation). Whenever there are multiple client request for the form, Forms server raised the Dr watson error (windows NT 4.0).
Kind request to anybody who has solution for the above.

Someone got the same message on a Suse 6.0. On a redhat 5.x, the
required files (libraries) are in packages
libstdc++-2.8.0-8
libstdc++-devel-2.8.0-8 (? may not be necessary)
You can get the above packages on redhat ftp and mirror sites.
Again, oracle on linux is really "RedHat-ish"!!!

Java Web Server 2.0 to Tomcat 3.2

My company was running servlets using Java Web Server on Solaris and I want to switch to Tomcat 3.2. The installation was fairly simple but I can't figure out how to deploy my previous servlets on Tomcat. Under Java Web Server, all my apps were in the /servlets folder. What is the quickest and easiest way to do this?

For Tomcat you place them in the /jakarta-tomcat-3.2.1/webapps folder. Each directory under webapps represents a different project. Let's say you have all your servlets grouped together in one directory. You'd make a directory (I'm assuming your root Tomcat directory is /jakarta-tomcat-3.2.1):
/jakarta-tomcat-3.2.1/webapps/myprojects/web-inf/classes
and place all your .class files in the classes folder. To access "myServlet", the browser will read (I assume Tomcat is on port 8080):
http://myserver.com:8080/myprojects/servlet/myServlet
Hope this helps.

JAVA WEB SERVER Problem

Hai,
I am using Java Web Server 1.2 . In JSP , when I use
ResultSet.previous(), it is saying that :
java.sql.ResultSet.previous() command not found. I do not know what to do ?
But, In java file, it is working fine without any problem .But, I need to implement in JSP only.
When I use the bean, which consists Rs.previous() also it says Resultset.previous() Command Not found It is very very urgent to me.
Pl help me.
Thanks & Regards

S,
1. Yes, you're rigth. Something is missing here.
2. If it works for Java App and not in JSP,
that would mean JAVA see your jdbc driver and not JSP
but then how come JSP can use Connection ???
3. I think we need some expert to clarify about setup on your machine. Some thing is not set up well so that JAVA app and JSP see at the same time. It look like only JAVA app see the whole.
4. Can you post your article in JDBC forum also in waiting?

Is SUN's Java Web Server 2.0 running on Solaris 8?

Hi,
I had installed Java Web Server 2.0 on Solaris 8 under /opt/SUNWjws/JavaWebServer2.0 directory.
When I tried to start up the java web server by calling "./httpd &" from /opt/SUNWjws/JavaWebServer2.0/bin directory I got the error message "jre was not found in /opt/SUNWjws/JavaWebServer2.0/jre/bin/../bin/i386/native_threads/jre"
The directory /opt/SUNWjws/JavaWebServer2.0/jre/bin/ directory does exist.
Thanks
Tom

Thanks.
After I add JAVA_HOME=/usr/java and PATH=/usr/java/bin:$PATH setting,the httpd still doesn't work.
But I try the httpd.nojre then it work.
Httpd.nojre runs jserv -nojre.

Problem installing Sun Java Web Server

Hi
I'm trying to install Sun Identity Server which need Sun Java Web Server...
I try to install identity server and web server using Sun Java Enterprise System Install Wizard...
When I came to page Identity Server:Sun Java System Web Server (3 of 6 ) and I entered Hostname, dir1.usmnet, I get an error pop-up window stating Host Name is not valid......but if I typed dir1.domain.com the error message didn' t appear.....
I'm using Solaris 9 on Intel platform. I have setup my network and able to ping to other valid hostname in my LAN....
FYI my network information are as follows
/etc/hosts
127.0.0.1 localhost
<my ip > dir dir.usmnet loghost
/etc/hostname.elxl0
dir1
/etc/resolv.conf
domain usmnet
nameserver <dns server ip>
search usmnet
I have also setup /etc/netmasks and /etc/defaultrouter
When I type the domainname command, nothing appeared
What when wrong, I could ping to my dns server and to other computer in this LAN, could anybody give a suggestion ?

OK, found the solution by myself.
The Administrator's Guide mentiones the possibility to install a certificate with the wadm CLI, so I tried that:
wadm> install-cert -v --config=www -y server -n Server-Cert /www.crt
Please enter token-pin>
ADMIN4086: The Certificate could not be installedThe CLI Reference Manual says for the command install-cert, option --replace*:
"Note --replace option of install-cert CLI is deprecated
and currently using this option may not work as expected.
For replacing a CA-signed certificate, users should delete the
cert using delete-cert CLI and then install the new one
using install-cert CLI."
wadm> install-cert -v --config=www -y server -n Server-Cert --replace /www.crt
Please enter token-pin>
ADMIN4112: No Private key foundOK, so maybe if I had installed the first certificate (before generating the new CSR) that would have worked, I don't know.
Deleting the old cert doesn't work at once:
wadm> delete-cert -v --config=www Server-Cert
Please enter token-pin>
ADMIN4139: Certificate Server-Cert is being referred to by listeners: http-listener-2So before deleting you have to remove the certificate from the listener. Then:
wadm> delete-cert -v --config=www Server-Cert
Please enter token-pin>
CLI201 Command 'delete-cert' ran successfully
wadm> install-cert -v --config=www -y server -n Server-Cert /www.crt
Please enter token-pin>
CLI201 Command 'install-cert' ran successfullyAfter re-adding the certificate to the ssl listener and deploying all the changes to the servers
everything is fine.
F.D.

Java Web Server

Hi There,
Is there anyone who can help me with a java issue?
I'm working on an assignment that deals with a simple java web server. The aim of the assignment is to create features that will allow the generation of dynamic web pages, the minimum requriement is that the current date be displayed on the web page. This is the method that sends the files is :
public void sendFile( String m ) throws IOException
if ( m == null ) return;
String file = baseDir + m.substring( 0, m.indexOf( ' ' ) );
String ext = file.substring( file.indexOf( '.' )+1 );
ext = ext.toLowerCase();
IO.Trace( "FILE", "File [" + file + "]" +
" Ext [" + ext + "]" );
File aFile = new File( file );
if ( aFile.canRead() )
theOut.putLine( "HTTP/1.1 200 OK ");
theOut.putLine( "Connection: close");
theOut.putLine( "Content-length " + aFile.length() );
if ( ext.equals( "jpg" ) || ext.equals( "jpeg" ))
theOut.putLine( "Content-type: image/jpg");
if ( ext.equals( "gif" ) )
theOut.putLine( "Content-type: image/gif");
if ( ext.equals( "htm" ) || ext.equals( "html" ))
theOut.putLine( "Content-type: text/html ");
theOut.putLine( "" );
theOut.copyFile( file );
} else {
theOut.putLine( "HTTP/1.1 403 Problem ");
I've done the following,
Date curDate = new Date();
TimeZone gmTz = TimeZone.getTimeZone ("GMT");
SimpleDateFormat sdf = new SimpleDateFormat ("dd MMM yyyy hh:mm:ss zzz");
sdf.setTimeZone (gmTz);
String source = "<br>Date: " + sdf.format ( curDate );
File aFile = new File ( file )
byte buf[] = source.getBytes();
OutputStream f0 = new FileOutputStream ( file, true );
for ( int i=0; i <buf.length; i++ )
f0.write ( buf);
f0.close();
Am i on the right track?
I would appreciate the help...
Thanks

Am i on the right track? Does it compile? Does it run without errors? Does it do what you want it to? If yes, then you're on the right track. If no, then illuminate your problems. It boggles my mind how often people ask if their code is good rather than running it and seeing for themselves...

Secure service in Java Web server 2.0

Hi all, I have installed a Java Web Server 2.0 without the secure service running, and everything works just fine.
Then I make a self-signed certificate with authstore, using key size 1024, MD5withRSA, hostname: <my computer> (testing on local net (maybe this is what fails?)), and all the other stuff. All looks good and certificate info looks like this:
Subject Information: CN=yodopc1, OU=SW dept, O=Yodoba, L=Z?rich, ST=Z?ric, C=CH
Issuer Information: CN=yodopc1, OU=SW dept, O=Yodoba, L=Z?rich, ST=Z?ric, C=CH
Dates Valid: Thu Jun 28 10:19:35 CEST 2001 --> Wed Sep 26 10:19:35 CEST 2001
Algorithm: MD5withRSA
Serial Number: 993716375
Then I exit, and restart (even tried rebooting machine).
Start webserver, type inn key password, and login to the Server admin applet. There it says:
Service -------------- Status ------ Port -- Network Address
Java web server ------ Terminated - -------
- Web service -------- Unknown --- 80 ----
- Secure Web service - Unknown --- 7070 --
If I try to start the server, it runs for about ten seconds before it is back to the same state again. Of course trying to access server through http(s)://localhost(:7070) results in a "Cannot find server..." If I delete the keys file in <JWS-root>, everything is back to where it was before I started creating the certificate.
I have seen that there are a lot of old (1-2 years old) Posts with similar and perhaps related issues, but none of witch have any replies that finds a solution. Hopefully someone can help my now...
All help and suggestion are Greatly appriciated.

Hi Sjurba,
Please follow this URL:
http://www.sun.com/software/jwebserver/faq/faq.html#f6
http://docs.iplanet.com/docs/manuals/messaging/sims35/install/postwa.doc6.html
Also read the below.
Client side workaround: Use Netscape Communicator 4.x instead of Netscape Navigator 3.x.
Java Web Server workaround: Use the VeriSign root certificate that is shipped in Java Web Server 1.1. Follow these instructions:
1.Copy or save the file named keys, located in the top level directory of your Java Web Server installation, to a secure place (for example, a floppy disk).
2.Locate the secure server certificate that VeriSign sent you.
3.Install Java Web Server 1.1 in a temporary directory. You don't need to run this server--you only need to run AuthStore to regenerate the keys file. (The install of
Java Web Server 1.1 does need not be on the same machine as the install of the Java Web Server 1.1.x that has the problem).
For the remainder of these instructions, 1.1.x server root is the installation directory of the Java Web Server 1.1.x that shows the problem. 1.1 server root is the
installation directory of Java Web Server 1.1
4.Copy the keys file from 1.1.x server root/ to 1.1 server root/.
5.Run AuthStore under 1.1 server root. AuthStore is in the bin directory. You will need to type in the server passphrase to launch AuthStore.
6.From the scrolling list, select the key that corresponds to the secure server certificate from VeriSign.
7.Click Import and type the full path of the certificate that you received from VeriSign.
8.Click Save to write a new keys file under 1.1 server root.
9.Click Exit.
10.Copy the new keys file from 1.1 server root/ to 1.1.x server root/.
11.Restart the Java Web Server 1.1.x under 1.1.x server root.
I hope this will help you.
Thanks

Sun Java Web Server 6.1SP4 deadlock, stops responding

Hi, i have a java web app on a Java Web SErver 6.1SP4 and when there are a lot of users the web server hangs, it stops responing. After a while (from 2 to 15 minutes) it start responding again. This serves neither dinamic nor static content. CPU usage is 100%. Just stoping and restarting the web server instance it works properly (even with the same or greater number of clients).
Reading many posts some one wrote to use pstack to see whats happening. I did it, but i can't interpret results (i think there is a deadlock but don't know if thats true and how to resolve it).
Any hint will be appreciated

hi
sorry for the delayed response.
well, the problem that you are trying to run into is very common when your server is getting good amount of load and uses large amount of servlet/jsp web applications running.
here is a url that you might find it a useful read
http://java.sun.com/docs/hotspot/gc1.4.2/index.html#4.%20Types%20of%20Collectors|outline
if you do not want to take this trouble reading this document and want a quick solution, you do can do couple of things:
- first understand how to size the heap

- understand that the system is paused because jvm is busy doing garbage collection before allowing the web server to continue.
- this can be avoided by properly tuning the jvm to how you think the server should behave. unfortunately, there is no miracle one one line to fix this issue
- by careful and decent analysis of your system, you can tune your jvm properly that it can scale very well without any glitches.
though, you will need to take the pain to learn the garbage collection acronyms and see what's best suited for you.
- first, you want to know what is happening inside the jvm before you proceed to optimize . you can do this by adding this option
-verbose:gc -XX:+PrintGCDetails
How to add this option in the server.xml , is by doing something like
start admin server -> manager your server -> click Java tab
-> click on JVM Option in the left side
-> Add this JVM option -verbose:gc -XX:+PrintGCDetails
-> restart the server
-> note, you do NOT want to leave the above option in the production environment as this will tremendously slow your application and this is meant to be only for development purposes.
- if your server is a multi processor server (has more than 1 CPU) and you want less pause time, you can typically try adding this jvm option to your server and restarting it.
-XX:+UseParNewGC -XX:+CMSParallelRemarkEnabled
here are few other short cut , jvm options that you also try in your devleopment environment before going to production.
Server application(Like Web Server 6.1) running alone on a large multi-processor server with 4gb of physical memory.
#java -server -XX:+AggressiveHeap
Two applications running on a large multi-processor server with 4gb of physical memory. Each java application instance is allocated a part of total system memory by an explicit specification of the maximum and minimum heap sizes.
#java -server -XX:+AggressiveHeap -Xms1024m -Xmx1024m
(again, do your research before you use this option in the production environment)

Sun Java Web Server and IPlanet

Are there any issues with running IPlanet and Sun Java Web Server at the same time. The old Web-site are in Servlet format and the new Web site will be deployed with a .war file, so I would like to run both at the same time until I have customized the new Sun Java Web Server instance. Is this possible and if so are there any issues with running them at the same time?

You can install iPlanet Web Server and Sun Java System Web Server on the same Solaris system, provided that each server is installed to a separate directoy. If each server is configured to listen on a different port and/or IP address, the two servers can run concurrently without problem.

Sun Java Web Server 7 and JNDI Jell

Hi all,
I am building a normal Java EE web app (WAR file), and I was originally developing on GlassFish v2.1 and everything was beautiful. Now, I found out our shared server is Sun Java Web Server 7, but the sys admin said everything should run fine as long as I wasn't using JSB's.
I downloaded and installed SJWS7 on my local machine so I could test my application against it, and JPA and SJWS7 are not getting along.
I am trying to bind my persistence.xml to the data source I created on SJWS7.
SJWS7 JDBC Resource: jdbc/pact
persistence.xml:
    <persistence-unit name="pact" transaction-type="RESOURCE_LOCAL">
        <description>PA/Circuit Tracking Development</description>
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <non-jta-data-source>java:comp/env/jdbc/pact</non-jta-data-source>
        <properties>
        ....There is nothing in sun-web.xml or web.xml that references this resource (although I tried that too, and no go).
The traceback I get is:
<code>Caused by: javax.naming.NameNotFoundException: PWC4216: Name pact is not bound in this Context

     ... 151 moreI've been trying for almost an entire day now, and googling isn't revealing anything helpful. I don't know what I'm doing wrong. Can anyone point me in the right direction?

u should be using
- default installation ( you can also use silent installation for this)
admin-server/bin/startserv
wadm delete-instance --user admin
wadm delete-config --user admin
