IPlanet 6.0 Servlet Engine with Weblogic 6.1 EJB engine
Does anyone have experience using iPlanet 6.0 Servlet engine with
WebLogic 6.1 EJB engine? The two engines will be located on separate
physical servers. If so, any information on the implementation would
be greatly appreciated (lessons learned especially). Would the cost
difference between using WebLogic's Servlet engine vs. iPlanet's
Servlet Engine be worth the attempt? I saw in some previous posts
that there were issues with how older versions of Weblogic RMI (T3)
Protocol worked and that Weblogic would only have one socket
connection for the iPlanet Servlet Engine through which all requests
will be multiplexed. This would be a bottleneck for any application.
Is this still true with the latest versions of these products?
Thanks,
Jon
WebLogic's Servlet engine is less than $1K / CPU I believe.

Hi
I am using right now a different servlet engine and most of my html pages
are referencing my servlets with
http://hostname/servlet/com.hotsafe.servletclass?param1=toto...
It seems that WebLogic is forcing me to add an virtual name to every servlet
I am using in the weblogic property file to map a servlet to a class name.
This unfortunately is forcing me to recode all my pages.
Most of the Web server/Servlet engines out there understand the /servlet/
URI, like Jserv, JSW, and JRun. So I am a little bit surprised. Any Ideas on
how to setup web logic with my current environment.
I have read the WebLogic documentation (admindocs/http.htm) and the FAQ but
without answers.

I guess since you say the ServletServlet is poor and SSI is not great
means that you've done very well with Servlets ;-)
It would be nice if you used the same <Servlet> tag syntax as every
other Servlet engine I have seen.
Please enlighten me on the JSP and Servlet tag stuff. I am not real
familiar with JSP yet. Are you saying I can rename my Servlet files to
end with .jsp and the <Servlet> tag will work?
Thanks

Best IDE to develop EJB/Servlet development with WebLogic
Hi,
I am prepearing a recommendation for our company's standard Java development
environment. I would appriciate any comment you guys might have on the best
IDE that supports J2EE and EJB and Servlet development that integrates with
WebLogic. I guess the best are Visual Age or Visual Cafe, anybody have any
experince/comment on any of those ?
Thanks

IPlanet 4.1 redirector issue with WebLogic 6.0 SP2
We have a servlet reading a PDF file and write out to the outputstream. We got an
IO exception when doing:
myOutputStream.write(byte[], 0, len);
The exception socket write exception: Broken pipe.
For the same program if we run it using weblogic's own internal
web server, everything run through fine.
Our pragram trace shows that the same servlet get called multiple times when using
IPlanet redirector, while only invoked once when using Weblogic's internal webserver.
Is this a redirector bug ? or there is some trick we missed out.Terry,
This is a known problem, and CR058420 was opened to address this
issue. For 6.0, there is not a patch available. The recommended
solution is to upgrade to 6.1 and apply the appropriate patch.

What is the default root of the servlet engine in IPlanet v6?
I am trying to get java based code to work on IPlanet's webserver/servlet engine version 6. The servlets are being inited, but they can't find their .properties files (xml variable files). I have been able to install this code on many servlet engines including JRun, Tomcat, and Jserv by placing the .property files into the default root of the servlet engine. In JRun, for example, it would be Allaire/Jrun/servers/default. I have tried placing them in several directories and adding them individually to the classpath, but still no luck. Any help would be greatly appreciated.
Hi,
Please place your claspath in jvm12.conf file.
Which will be under /server-root/https-instance/config/jvm12.conf.
For more info about how to set classpath for running servlet. Please look out the below link.

How to use java security in a servelt with weblogic as a servlet engine?
Hi,
i want to use standard java security with a user defined permission in
servlet with wls 5.1 (Win nt) as a servelt engine.
WL-Home: f:\weblogic
Server: f:\weblogic\elan
Servlet: f:\weblogic\elan\elan\ServletGropsTest.class
The Servlet is registered in weblogic.properties:

The servlet code is:
SecurityManager m = System.getSecurityManager();
if (m != null) m.checkPermission(new AndisPermission("x","y"));
WLS throws the permission-exception:

Problem in servlet engine (WLS 7.0) with the chunked transfer
Hi,
While using jakarta-slide on weblogic 7.0, I encountered the following
problem while uploading files using WebDAV servlet deployed on WLS:
"**** This file has a corrupted %%EOF marker, or garbage after the
%%EOF."
Is this is a problem with the way that WLS servlet engine is handling
chunked transfers ?
According to the change request 084847, "For chunked
transfer, WebLogic Server was including a hexadecimal number which
other
servlet engines used to ignore. This has been fixed WLS 6.1 sp 4."
Is this fixed in WLS 7.0 ? I could not find this in the resolved bugs
list for WLS 7 SP1. If this has not been fixed in 7.0, any idea when
this fix would make it to WLS 7.0 ?
Any pointers would be of great help.
Thanks,
Jeeji.

WebLogic Server vs Embedded Servlet Engine
We have licensing for WebLogic Server, and I was wondering if there were any benefits to using it over the embedded servlet engine for hosting Collaboration 4.5 or Publisher 6.4?
hi.
WebLogic Express supports the following:
Servlets, JSP, JDBC, JNDI, JTA, JAAS, JAXP, RMI, and clustering. You
can build a cluster of WLExpress instances.
Hope this helps,

Hello All,
I forgot the subject line. I'm trying to set up iPlanet Directory 4.1 with
WebLogic 5.1 Sp3 on Solaris7. Weblogic will see the users I specify
(username,groupname) but not
the group, additionally it will allow you to login if you know the
username and anypassword. I get the following error when loading the
http://localhost:port/AdminRealm. I've gone through the LDAP
properties file a million times. Lastly, now it does a core - dump
while trying to start.
Please help.

Iplanet Integration with weblogic
Dear All,
We want to integrate IPlanet with weblogic application server.
Please suggest the procedure for the same i.e docs , URLs.
Thanks
Prashantkindly take a look at our reverse proxy plugin
http://docs.sun.com/app/docs/doc/819-0902
also, please note that if you need to serve only servlet / jsp , then sun java system web server 6.1 has integrated container that can do the job very well.
for any further business process logic , you can use the app servers with 'reverse proxy enabled' so that these requested can be forwards to either Sun Java System Application Server or Web Logic

A problem with servlets with WebLogic 4.5.1 SP11
Hello,
We have developed a client that connects to servlets in WebLogic 4.5.1. Some of the servlets use sessions to store data, and they receive some parameters from the client to retrieve information from a database.
When we use WebLogic 4.5.1, everything works fine. However, when we upgrade it to Service Pack 11, we find a problem. If we make a servlet that receives some parameters, but it does no use sessions, everything is correct. If we make a servlet that does not receive any parameter, and we use sessions, we find no problem either. But if we make a servlet that receives parameters and uses sessions within the doPost() method, there is an exception when we call the method Request.getSession(true).
I would thank any help about this point, since I'm not sure if this is the result of a bug, or if there is a new parameter that we have to set in the file weblogic.properties, or any other reason.
The code of our servlet is as simple as follows:
public void doPost(HttpServletRequest request, HttpServletResponse response) throws IOException {
ObjectInputStream in = new ObjectInputStream(request.getInputStream());
String arg = null;
String arg2 = null;
String arg3 = null;
try{
arg = (String)in.readObject();
arg2 = (String)in.readObject();
arg3 = (String)in.readObject();
}catch(Exception e){
// Get the session and the counter param attribute
HttpSession session = request.getSession(true);
// WE GET THE EXCEPTION AT THIS POINT.
Integer ival = (Integer) session.getValue("simplesession.counter");
if (ival == null)
// Initialize the counter
ival = new Integer(1);
else
// Increment the counter
ival = new Integer(ival.intValue() + 1);
// Set the new attribute value in the session
session.putValue("simplesession.counter", ival);
// Output data
ObjectOutputStream out = new ObjectOutputStream(response.getOutputStream());
out.writeObject(ival);
out.close();
On the other hand, the client invokes the serlvets using the following code:
public int servletClient(String usuario,String password) {
int numero = 0;
try{
// Input parameters
Serializable[] objs = {"login",usuario, password};
// Invokes the servlet
ObjectInputStream in = ServletWriter.postObjects(urlServlet, objs); // SEE BELOW...
// Get the results
numero = ((Integer)in.readObject()).intValue();
in.close();
}catch(Exception e){
e.printStackTrace();
static public ObjectInputStream postObjects(URL servlet, Serializable objs[]) throws Exception
URLConnection con = servlet.openConnection();
con.setDoInput(true);
con.setDoOutput(true);
con.setUseCaches(false);
con.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
// Write the arguments as post data
ObjectOutputStream out = new ObjectOutputStream(con.getOutputStream());
int numObjects = objs.length;
for (int x = 0; x < numObjects; x++) {
out.writeObject(objs[x]);
out.flush();
out.close();
return new ObjectInputStream( con.getInputStream() );
// THE CLIENT CODE FINISHES HERE

Can anybody solve it?
Best wishes, Oleg.
Java will not allow us to reload any class that is dependent on a native
library. I suggest that any classes that depend on native code should be
put in the system classpath. If you change these classes or the native
library you will need to restart your server.

Error loading servlet: weblogic.servlet.FileServlet with v. 4.0.3
Servlets have been working for months. Suddenly, I'm getting
this error (see below) as soon as I try to hit a servlet.
The startup process looks normal. I've re-installed WL v 4.0.3
several time, gotten the license in place, so on and so forth,
but cannot get around this problem. "weblogic.properties" file
still reads:
weblogic.httpd.register.file=weblogic.servlet.FileServlet
All my servlets and EJBs have been registered, and db connection and
pool made, as usual. As I said above, everything looks normal until
I try to hit a servlet.
[... startup output tidied up a bit ...]

Does anyone have any idea as to what could cause this?

Did you register your servlets after reinstalling. FileServlet is only for handling html pages. It has no role in loading servlets.
