Apache 1.3.33 and servlets?
Does Apache 1.3.33 can run the servlets?
I asked because server's admin can not clarify it for me :)
No (assuming you mean Apache httpd). Apache httpd is a webserver, not a Java Application Server / Servlet Container. Check out http://tomcat.apache.org/ for servlet support.

Problem with WebLogic 10.3.3, Apache 2.2.3 and WebLogic Apache proxy plugin
I have a problem with using Apache 2.2.3 as a WebLogic SSL proxy. I have Apache 2.2 running and successfully configured an SSL cert, config in ssl.conf is...
<VirtualHost secure.daftdonkey.com>
# Setup SSL for secure.daftdonkey.com
ServerName secure.daftdonkey.com
SSLEngine On
SSLCertificateFile /oracle/secure/secure.daftdonkey.com.crt
SSLCertificateKeyFile /oracle/secure/secure.daftdonkey.com.key
SSLCertificateChainFile /oracle/secure/gd_bundle.crt
</VirtualHost>
This works fine
Now I want Apache to proxy requests to my WebLogic Server and secure them over SSL as well
e.g. a request to https://secure.daftdonkey.com/service goes to https://weblogic.internal.site/service
I have downloaded and configured the weblogic module and tested it handling traffic for HTTP and that worked, then I switched the WebLogic module to use SSL.
LoadModule weblogic_module modules/mod_wl.so
<IfModule mod_weblogic.c>
WebLogicHost weblogic.internal.site
WebLogicPort 16101
Debug ALL
SecureProxy ON
WLSSLWallet /oracle/secure/my-wallet
WLLogFile /tmp/wl-proxy.log
</IfModule>
<Location /service>
SetHandler weblogic-handler
</Location>
Starting Apache throws the error. I think this is my main problem, i've searched support.oracle.com and not found anything.

How to setup my computer to run JSP and Servlets
I want to setup my computer to run JSP and Servlets.
What kind of Servers and other tool i need to install to run JSP and Servlets.
Plz, Help me to start my work on JSP.
Regards,
Usman Alihello
JSP and servlet is web programming, may be little bit different to development local application.
1st, you should have two computers: one is server and the other is local workstation. This server should have a static IP address, that other people can go into your server. Workstation is any computer normal you use it.
2nd, you need to setup your server in: OS(linux or windows 2000), web server (jrun, apach or Tomcat etc. ), as well as install JDK, servlet.
3rd, your local workstation just use as programming editor and open a browser to testing, anytime you write your code, then ftp to server to test.
Reality, you have many technical thing to solve, eg setup web server etc. However, you can write your source code and test it, then open to outside people.
hope to helpness, if anything don't uderstand, you can post again or send email to me [email protected] Since I just have setup this configuration in my university for my project. -
Load balancing for JSPs and servlets
Hi:
I am using IIS as the proxy server, with the WLS plug-in, to a WLS
cluster. This provides round robin load balancing just fine. Will it
provide weight based load balancing if I set 'weblogic.system.weight'
differently on each server, or is that not relevant for clustering JSPs
and servlets?
Sincerely,
Ashish
Currently the plugins ( for NES, IIS and Apache) just use the round robin
algorithm. the property
weblogic.system.weight is used only be weblogic's replica aware clusterable
RMI/EJB stubs.
To use this property for your JSP/Servlet load balancing you have to use
weblogic server as proxy fron-ending your weblogic cluster.

Can anybody help me, please? I need this in a short time for my thesis.From the stack trace, it says that the mm.mysql Driver was not found. This means that you have not included the mySQL JDBC driver in your classpath. You have to download the mySQL driver jar file and place that in the "lib" folder under the Tomcat installation. Then, make sure that the said jar file is included in your classpath. Hope this helps

SQLJ JSP and SERVLETS which Environment?
Hello,
I am attempting to run the samples on Chapter 5 of the
following documents with partial success.
http://technet.oracle.com/docs/products/oracle8i/doc_library/817_
doc/java.817/a83726/oraext2.htm
http://download-west.oracle.com/otndoc/oracle9i/901_doc/java.901/
a90208/oraext.htm#1015820
1. Do I need the Apache+Jserv environment to run SQLJ and JSP?
2. What do I need to do run SQLJ on oc4j if possible?
3. I dont know how to load(?) and/or run this .sqljsp file.
<%@ page language="sqlj"
import="sqlj.runtime.ref.DefaultContext,oracle.sqlj.runtime.Oracl
e" %>
<HTML>
<HEAD> <TITLE> The SQLJQuery JSP </TITLE> </HEAD>
<BODY BGCOLOR="white">
<% String empno = request.getParameter("empno");
if (empno != null) { %>
<H3> Employee # <%=empno %> Details: </H3>
<%= runQuery(empno) %>
<HR><BR>
<% } %>
<B>Enter an employee number:</B>
<FORM METHOD="get">
<INPUT TYPE="text" NAME="empno" SIZE=10>
<INPUT TYPE="submit" VALUE="Ask Oracle");
</FORM>
</BODY>
</HTML>
<%!
private String runQuery(String empno) throws
java.sql.SQLException {
DefaultContext dctx = null;
String ename = null; double sal = 0.0; String hireDate = null;
StringBuffer sb = new StringBuffer();
try {
dctx = Oracle.getConnection("jdbc:oracle:oci8:@", "scott",
"tiger");
#sql [dctx] {
select ename, sal, TO_CHAR(hiredate,'DD-MON-YYYY')
INTO :ename, :sal, :hireDate
FROM scott.emp WHERE UPPER(empno) = UPPER(:empno)
sb.append("<BLOCKQUOTE><BIG><B><PRE>\n");
sb.append("Name : " + ename + "\n");
sb.append("Salary : " + sal + "\n");
sb.append("Date hired : " + hireDate);
sb.append("</PRE></B></BIG></BLOCKQUOTE>");
} catch (java.sql.SQLException e) {
sb.append("<P> SQL error: <PRE> " + e + " </PRE> </P>\n");
} finally {
if (dctx!= null) dctx.close();
return sb.toString();
%>
I named above file as test2.sqljsp then I tried these procedures:
a) $ ojspc test2.sqljsp --these created all the files
b) $ loadjava -u -v scott/tiger _test2.class -resolve
this generated:
initialization complete
loading : _test2
creating : _test2
resolver :
resolving: _test2
errors : _test2
ORA-29521: referenced name test2$_jsp_StaticText could not
be found
ORA-29521: referenced name test2SJProfileKeys could not be
found loadjava: 2 errors
c) listed the directory and both these files are there but it
cannot resolve or find it?
d) I recall reading something about publishjsp command but I have
to establish a session shell with OSE? this part is very
confusing and am not sure what to do here.
e) not sure if i need to publish the loaded class (create a
procedure? so it can be known to the rest of plsql?)
A step by step procedure is very much appreciated. fyi.. I
have Oracle 8.1.7, + oc4j, I can run sqlj from command line
and class files generated I can run. I can also run JSP and
servlets on the oc4j accessing the database. It is this SQLJ
that throws me off balance. If you include Jdeveloper steps
ro run SQLJ thats also welcome.
Thanks in advance for kind responses posted.In many Model-View-Controller web applications implemented using J2EE, servlets are as controllers to direct the flow between the model and view. While servlets can output HTML code directly, it is much better to use JSPs for the most part. JSPs contain HTML and possibly Java scriptlets. The J2EE container will typically compile JSPs into servlets. While you could use a JSP as a controller, there are drawbacks to that approach. To minimize the amount of Java code in your JSPs, you can either use the tags provided by the JSP spec or use tag libraries written by someone else or yourself. See the JSTL for one such example.

Hi,
Can anyone recommend a good, recently published book on JSPs and Servlets?Things on the Internet may be up to date, but they
aren't necessarily as usable as a book.
For example. I am just trying to learn Ant. There's
the Ant user manual at http://ant.apache.org/manual/
for a start. But to find anything you have to click on
a link, then on another link, then on another link.
And it doesn't have an index so even if you know what
you are looking for, you still have to start at the
beginning and click randomly until you find it. And
you can't easily browse through looking for
interesting things.
Not to mention that it doesn't give you any
suggestions on what to do and why. It simply describes
the various XML elements used by Ant. For example it
may be possible to have an element which is like a
subroutine, so you can call the same code from
multiple targets. But if it is, I haven't found out
how yet.
Sometimes a book is better. In this case it would be.I agree with DrClap. Books do have a shelf life in IT, but they're definitely worth having.

LDAP protection for JSP and Servlets
Environment: WL 5.1 sp 8 on Solaris 7
Question: I want to use LDAP Security on my site. Does Weblogic only utilze LDAP
for servlets. What about my JSP files? And no, I can't protect just a directory
with iPlanet Web Server because my JSP files are all over my directories and my
servlets are in my /servlets directory. I need security on some of the jsp files.
how would I accomplish this?Hello
What do I install in order to create and use .jsp's
and servlets and jdbc connectivity as well? Is it
J2SE or J2EE. The answer is "Yes."
In order to use J2EE, you need J2SE. If you do not feel comfortable with J2SE and programming Java in general (as is suggested by not being able to differentiate between J2SE and J2EE and how to download one/both), J2EE may be a bit complex to get started with.
My suggestion:
1) Start Here: http://java.sun.com/learning/new2java/index.html
2) Download J2SE: http://java.sun.com/j2se/1.5.0/download.jsp choose the JDK 5.0 Update 3
3) Do a beginners Java Tutorial: http://java.sun.com/docs/books/tutorial/index.html
4) Read a book, try a lot, get comfortable doing it.
Then Choose the JDBC:
http://java.sun.com/docs/books/tutorial/jdbc/index.html
Then, only after being compfortable in how Java and JDBC work, move to J2EE
1) Download a Server (examples):
Full J2EE implementation: J2EE Software Development Kits (SDK)
Servlet/JSP Engine (Tomcat): http://jakarta.apache.org/site/downloads/downloads_tomcat-5.cgi
There are others, Tomcat is fairly popular.
2) Read the server's documentation thoroughly
3) Read a J2EE tutorial: http://java.sun.com/j2ee/1.4/docs/tutorial/doc/index.html
Note: depending on your server, the above tutorial may only be partially relevant.
The download section is overwhelming
and confusing to me :(
Thanks for any guidance. -
How to track the same session using both jsp and servlets
Hello, guys:
"how to use jsp and servlet to track the same session",
it seems to me my logoff.jsp never realize the session I established in my servlets.
Here is how I set my session in my servlets:
" HttpSession session = req.getSession(true);
session.setAttribute("userid",suserid);"
Here is how I invalidate my session in my logoff.jsp
" <%@ page language= "java" %>
<%@ page import="javax.servlet.http.HttpSession" %>
<%@ page session="false"%>
Our Session id is : <%= session.getId() %>
<% session.removeAttribute("userid");
session.invalidate();
%>
Our Session id is : <%= session.getId() %>"
but when I try to logoff using the logoff.jsp
I always get following error message.
"/home/jiao/jsp_webserver/tomcat/work/Standalone/localhost/syllabus/htmls/logoff_jsp.java:50: cannot resolve symbol
symbol : variable session
location: class org.apache.jsp.logoff_jsp
out.print( session.getId() );"
T.I.A.
[Edited by: jiveadmin on Jun 18, 2003 10:32 AM]
[Edited by: jiveadmin on Jun 18, 2003 10:33 AM]So,
<%@ page session="false"%>
That means the jsp never instantiates the build in session object.
<%@ page session="true"%>
means jsp will instantiates a session object if there are no existing ones
how about I just delete the line,
does that mean the jsp will find the existing session object for me?
So I can do something like
Our Session id is : <%= session.getId() %>
<% session.removeAttribute("userid");
session.invalidate();
%>
directly.

Can I use the Apache server that comes with Linux to execute .jsp file and Servlet's.class file. If no, what other container can I use?
Thanks in advance!Steve, thanks for your reply first.
I had downloaded "apache-tomcat-5.5.20.tar.gz" from Apache Tomcat's website. And I tried reading the User's Guide(http://tomcat.apache.org/tomcat-5.5-doc/setup.html) on how to setup the Tomcat server.
Unfortunately, I could not find the LInux eperating system. I know that Unix is similiar to Linux in architecture. Is it means that I could follow the Unix Daemon to setup the tomcat server?
I also found that it is difficult for me to understand the content in Unix Daemon as I am not familiar with Linux environent too. But, I need to develop web application in Linux environment.
If anyone could help, I would be appreciate! -
Need some help with Slow Downs in Java3D and Servlets
Hi,
I realize that there is a separate forum for Java 3D, but I posted there, and did not get any response. This is kinda the crux of my program, so I would like to invite anybody on this forum with knowledge of Java 3D and servlets to give it a stab. Between this post and that one, there are TWENTY duke dollars up for grabs.
Thanks.
http://forum.java.sun.com/thread.jspa?threadID=603198Let me have an educated guess.
You calculated the time elapsed before sending in a server request - and at that point you have you updated timeLastStateChange yet, which means by the time of the next calculation of time elapsed this apparent delay is not counted in, hence the slow down in animation rate.
Hope this helps~

Web service and servlets in the same project...web.xml?
Hello, I have a problem with my web service.
I have a server, which displays a web service. I programmed this service with JAXRPC.
I have a client, in another directory. I succeded in compiling, deploying and running the web service.
The problem is that after I tried to integrate this service in an existing project. This project contains servlets. In these servlets, I'm using sessions.
These servlets are on the same side as the server of the web service. Because of the implementation of my code, I'd like to use in the class that represents the server of the service, the same session as the one I'm using in the servlets.
But of course, it's not working by itself. I know there's something to do with the web.xml files.
The thing is that I created a web.xml file for the service, and another for the servlets.
I was thinking of joining both of them in one xml file, but everything crashes then...
Could someone tell me how to create a project with a web service and servlets, and mostly how to configure the xml file??
Thanks for any help

Deploying a WAR file containing .jsp and servlets (also uses JNI)
Deploying a WAR file containing .jsp and servlets (also uses JNI) on Windows 2000
We had problems making it initially work on Sun ONE Web Server 6.0 Service Pack 1 because of lack of good iPlanet Web
Server documentation on deploying such files.
This is how we went about it:
1) Make one of the servlet and JSP (must call another Java Class) web application (.war) examples work with iPlanet Web
Server.
C:\iPlanet\Servers\plugins\servlets\examples\web-apps\HelloWorld\HelloWorld.war
and
C:\iPlanet\Servers\plugins\servlets\examples\web-apps\jakarta-examples\jarkarta-examples.war
a) Go to your Web Server Administration to deploy the application using GUI Web Application Deploy.
(We usually use command line, we experienced some issues with the GUI version, but maybe it is fixed in the new Web Server
service packs)
From browser, open http://yourserver:8888/
Click on Select a Server:Manage
Click on Virtual Server Class
Click on https-yourserver
Click on the Web Applications Tab
Then, click on Deploy Web Application
Enter the following -
WAR File On: Local
WAR File Path: C:\iPlanet\Servers\plugins\servlets\examples\web-apps\jakarta-examples\jarkarta-examples.war
Application URI: /jakarta
Installation Directory: c:\iPlanet\examples\jakarta-examples
By clicking on OK it deployed the application.
I can verify that it is deployed by selecting "Edit Web Applications" and I see the following entry:
Edit /jakarta c:/iPlanet/examples/jakarta-examples
Also, c:/iPlanet/examples/jakarta-examples should have the similar following directory structure ..
- [images]
- [jsp]
- index.html
- [servlets]
- [META-INF]
- [WEB-INF]
- [classes]
- [tlds]
- web.xml
- index.html
I restarted the server and accessed it using the following URL from my IE browser:
http://yourserver/jakarta/index.html
Then I clicked on the JSP Examples and tried some JSP examples.
b) Alternatively, you can also deploy the same example from the command-line.
Make sure C:\iPlanet\Servers\bin\https\httpadmin\bin\ is in your path
wdeploy deploy -u /jakarta
-i yourserver
-v https-yourserver
-d c:\iplanet\examples\jakarta-examples
C:\iPlanet\Servers\plugins\servlets\examples\web-apps\jakarta-examples\jarkarta-examples.war
Restart the web server (I don't think you have to restart, but .. might as well).
2)Deploy your web-application
My Foo.war has the following structure.
You can use jar tf Foo.war to look at the file contents from command line (assuming you have JDK installed and the bin is
in your PATH)
Foo.war
- [META-INF]
- [WEB-INF]
- web.xml
- [classes]
- Bar.class
- MoServlet.class
- [lib]
- ThirdParty.jar
- [natlib]
- extlib.dll
- foo.jsp
Here is our application scenario:
foo.jsp uses a class call Bar (it is not in any package). The Bar java class uses classes from ThirdParty.jar. The
ThirdParty.jar in turn uses JNI to load library extlib.dll. foo.jsp also calls /servlet/Mo as well.
Now to deploy it, do the following:
(a) Make sure that within foo.jsp, you import the Bar class ( I don't know why you have to do it, but if you don't you get
JSP compile error).
<%@page language="java" import="Bar" contentType="text/html"%>
(b) Check web.xml (for Servlets)
Within web.xml, make sure you have the following mappings:
<servlet>
<servlet-name> MoLink </servlet-name>
<servlet-class> MoServlet </servlet-class>
</servlet>
<servlet-mapping>
<servlet-name> MoLink </servlet-name>
<url-pattern> /servlet/Mo </url-pattern>
</servlet-mapping>
(c) Deploy the application
Using command line:
wdeploy deploy -u /foo
-i yourserver
-v https-yourserver
-d c:\iplanet\examples\foo-dir
Foo.war
(d) Change web-apps.xml file (for picking up ThirdParty.jar)
It is located in
C:\iPlanet\Servers\https-yourserver\config
You should see something similar to following after successful deployment.
<web-app uri="/foo" dir="C:\iPlanet\examples\foo-dir" enable="true"/>
Change it to look like following to pick up the ThirdParty.jar
<web-app uri="/foo" dir="C:\iPlanet\examples\foo-dir" enable="true">
<class-loader reload-interval="300"
classpath="C:/iPlanet/examples/foo-dir/WEB-INF/lib/ThirdParty.jar"
delegate="false"/>
</web-app>
(e) Change jvm12.conf file (for JNI)
It is located in
C:\iPlanet\Servers\https-yourserver\config
Add or uncomment the following lines:
#optional - just helps with instrumenting the jsp and servlet code
jvm.include.CLASSPATH=1
jvm.enableDebug=1
nes.jsp.enabledebug=1
jvm.trace=7
jvm.verboseMode=1
#required for JNI
java.compiler=NONE
jvm.classpath=.;C:\JDK1.3.1\lib\tools.jar;C:/iPlanet/Servers/plugins/servlets/examples/legacy/beans.10/SDKBeans10.jar;
jvm.option=-Xrs
jvm.option=-Xnoagent
# not sure if this is needed for iPlanet web server
jvm.option=-Djava.library.path=C:/iPlanet/examples/foo-dir/natlib/ -Djava.compiler=NONE
(f) Change magnus.conf file (for JNI)
We HAD to change this file in order for ThirdParty.jar file to pick up the native C++ code using JNI. Apparently, the
iPlanet Web Server doesn't pick the Environment Variable Path. Because when we had the directory containing the DLL just
in Path, it didn't work.
Change Extrapath directive:
ExtraPath C:/iPlanet/Servers/bin/https/bin;${NSES_JRE_RUNTIME_LIBPATH}
to
ExtraPath c:/iPlanet/examples/foo-dir/natlib;C:/iPlanet/Servers/bin/https/bin;${NSES_JRE_RUNTIME_LIBPATH}
(g) Apply changes from the Web Server Administration Console and Restart the web server.
You should be able to see the behaviour that you want from your application.
http://yourserver/foo/foo.jsp

SonuDeploying a WAR file containing .jsp and servlets (also uses JNI) on Windows 2000
We had problems making it initially work on Sun ONE Web Server 6.0 Service Pack 1 because of lack of good iPlanet Web
Server documentation on deploying such files.
This is how we went about it:
1) Make one of the servlet and JSP (must call another Java Class) web application (.war) examples work with iPlanet Web
Server.
C:\iPlanet\Servers\plugins\servlets\examples\web-apps\HelloWorld\HelloWorld.war
and
C:\iPlanet\Servers\plugins\servlets\examples\web-apps\jakarta-examples\jarkarta-examples.war
a) Go to your Web Server Administration to deploy the application using GUI Web Application Deploy.
(We usually use command line, we experienced some issues with the GUI version, but maybe it is fixed in the new Web Server
service packs)
From browser, open http://yourserver:8888/
Click on Select a Server:Manage
Click on Virtual Server Class
Click on https-yourserver
Click on the Web Applications Tab
Then, click on Deploy Web Application
Enter the following -
WAR File On: Local
WAR File Path: C:\iPlanet\Servers\plugins\servlets\examples\web-apps\jakarta-examples\jarkarta-examples.war
Application URI: /jakarta
Installation Directory: c:\iPlanet\examples\jakarta-examples
By clicking on OK it deployed the application.
I can verify that it is deployed by selecting "Edit Web Applications" and I see the following entry:
Edit /jakarta c:/iPlanet/examples/jakarta-examples
Also, c:/iPlanet/examples/jakarta-examples should have the similar following directory structure ..
- [images]
- [jsp]
- index.html
- [servlets]
- [META-INF]
- [WEB-INF]
- [classes]
- [tlds]
- web.xml
- index.html
I restarted the server and accessed it using the following URL from my IE browser:
http://yourserver/jakarta/index.html
Then I clicked on the JSP Examples and tried some JSP examples.
b) Alternatively, you can also deploy the same example from the command-line.
Make sure C:\iPlanet\Servers\bin\https\httpadmin\bin\ is in your path
wdeploy deploy -u /jakarta
-i yourserver
-v https-yourserver
-d c:\iplanet\examples\jakarta-examples
C:\iPlanet\Servers\plugins\servlets\examples\web-apps\jakarta-examples\jarkarta-examples.war

Hi friends,
[please forgive me if i am posting this in the wrong forum, all seems same to a fresher]
Now, to my problem..i need a suggestion, a way or a method to implement the following!
I am supposed to create a servlet that reads data from oracle database. Once i retrive the data (for example: 6 rows of a table having 4 attributes), i am supposed to pass this data to a JSP page where the data has to be formatted and displayed properly. If i call the same servlet from a different JSP, i should be able to access the data in that JSP and format it in a different way. How do i pass the data to JSP? what method i can use to achieve this task?
Note: I already know about PrintWriter pw = response.getWriter(); and then printing the formated HTML page..but i want to keep the formatting to JSP part and send only the data part that i can access in JSP

Note: I already know about PrintWriter pw = response.getWriter(); and then printing the formated HTML page..but i want to keep the formatting to JSP part and send only the data part that i can access in JSPA wise approach - I wish more prople woiuld be as thoughtful. -
How to upload a file into server using j2ee jsp and servlet with bean?
How to upload a file into server using j2ee jsp and servlet with bean? Please give me the reference or url about how to do that. If related to struts is more suitable.
Anyone help me please!u don't need j2ee and struts to do file uploading. An example is as such
in JSP. u use the <input> file tag like
<input type="file"....>You need a bean to capture the file contents like
class FileUploadObj {
private FormFile srcFile;
private byte[] fileContent;
// all the getter and setter methods
}Then in the servlet, you process the file for uploading
* The following loads the uploaded binary data into a byte Array.
FileUploadObj form = new FileUploadObj();
byte[] byteArr = null;
if (form.signFile != null) {
int filesize = form.srcFile.getFileSize();
byteArr = new byte[filesize];
ByteArrayInputStream bytein = new ByteArrayInputStream (form.srcFile.getFileData());
bytein.read(byteArr);
bytein.close();
form.setFileContent(byteArr);
// Write file content using Writer class into the destination file in the server.
