How to restart the Servlet Engine?

Hi
I am configurating a WebDAV repository in KM
I am required to restart the Servlet Engine.
Can anyone please explain me how to restart the servlet engine.
Thanks in advance

Basically it means to restart the Java engine!
On way to do this is to use the NetWeaver Administrator tool (http://portal:port/nwa) and navigate to Administration -> Systems -> <Your SID> and then you will see your dispatcher and server nodes. Just restart the server0..n nodes.
Cheers

How to restart the J2EE Engine

I ran a couple tests the other day, and the next time I looked the J2EE Engine was down. (Could not send or receive PTP messages to it).
When I brought up the J2EE Engine Administrator, it put upt the following help box:
<b>Unable to lookup connection default
http:host1:8101/msgserver/text/login returned empty list of connection parameters</b>
I had to reinstall to get it to work.
Does anyone know how to restart the J2EE engine ?
Thanks, John

Hi,
judging by the URL given in the error message (which is a URL that queries the message server), your engine must be of 6.40 version. Well, on 6.40 you should have the SAP Management Console (SAP MMC) that you can open and start the engine from. TO open it, go to Start -> Programs -> SAP Management Console. Inside, locate your SAP System, right-click on it and select Start.
That's it.
Just for a reference, <a href="http://help.sap.com/saphelp_nw04/helpdata/en/9b/dd7277f3e64ecba59f7fbac7edd2fe/frameset.htm">this</a> page contains also some screenshots of the MMC.

Restart the servlet engine

I made some changes to the KM -> Content Mgt -> Repository Managers -> BO Repository and saved them.
I got a message at the top telling me to:
"restart the servlet engine"
So I'm wondering if that means restart the J2ee or just restart some repository service?
Mike

Michael,
Pls restart the j2ee engine. This is normally reqd if you make changes in Rep managers.

How can the servlet engine create objects of interfaces?help

hello,
I have this basic fundamental query...when using servlets i noticed that so many methods in the HttpServlet class take as arguments objects of the type "Interface"..where as basic principle in java is u cant instantiate interfaces...interfaces r mere templates which u implement by ur own custom classes.
For example the doGet method recieves from the servlet engine(servlet container) two arguments which r HttpServletResponse object and HttpServletRequest object..and u use these further to make use of the methods of the inmterfaces..which again is a mystery to me...why?
here is why:-
since HttpServletResponse and HttpServletRequest r interfaces..they cant be instantiated...and now that the sevlet engine provides objects of these interfaces...how come u r able to to use the methods of these interfaces...for r they not empty methods?..
example how r u able to make the sendRedirect() method of HttpServletResponse interface work...is this method not an empty method?
there r several interfaces...whose objects r being used and passed in this similar fashion....(for example there r many methods that return an enumeration...which is used as if it were an ordinary class that can be instantiated..and whose methods r non empty emthods)
please help me resolve this mystery
sheeba

Don't call me "u". The word is "you". Likewise "are" and not "r".
The servlet engine creates objects of concrete classes that implement those interfaces. If you want to find the names of those classes in your particular server, you could use for examplereq.getClass().getName()

Restart the Java-Engine in a dual stack installation (java+abap)

Hi,
how is it possible to restart or start only the j2ee-engine in a dual stack installation. We have a JAVA- and a ABAP-Stack and want only restart the JAVA-Stack. In windows i can use the MMC of SAP but how is it possible in UNIX.
regards,
sharam

Hi Eric,
i konw this TR, it doesn't work. There are two possibilities:
restart j2ee-local
restart j2ee-global
we try it with j2ee-local because we use a dual stack installation. What could be the problem. Is there an other possibility? How can i restart the j2ee-engine directly on my unix machine?
regards,
sharam

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.

Forcing restart of SERVLET ENGINE?

We are currently running a servlet which has several associated classes.
          If changes are made to the core servlet class no restart of the server is
          needed as changes are picked up automatically. However, when changes are
          made to the associated classes the changes are not picked up until the
          server is restarted.
          Is there any way to force a restart of the servlet engine so these changes
          are picked up without having to shut down the server?
          Thanks for your help
          Joanne


Hi!
Open J2EE anmitistrator tool, then go to Server > Services > Deploy, open server > servlet_jsp and restart irj service.

Please update your forum profile with a real handle instead of "914824".
When you have a problem you'll get a faster, more effective response by including as much relevant information as possible upfront. This should include:
<li>Full APEX version
<li>Full DB/version/edition/host OS
<li>Web server architecture (EPG, OHS or APEX listener/host OS)
<li>Browser(s) and version(s) used
<li>Theme
<li>Template(s)
<li>Region/item type(s)
With APEX we're also fortunate to have a great resource in apex.oracle.com where we can reproduce and share problems. Reproducing things there is the best way to troubleshoot most issues, especially those relating to layout and visual formatting. If you expect a detailed answer then it's appropriate for you to take on a significant part of the effort by getting as far as possible with an example of the problem on apex.oracle.com before asking for assistance with specific issues, which we can then see at first hand.
I am going to have over 50 buttons in a page, Why? This would be a most unusual UI paradigm. I've never seen such a page, which suggests that whatever you want to do is normally done another way. Please explain the requirement in more detail.
just wanted to know if its possible to do something like this in java.
Java is not used in programming APEX UI behaviour. Java and JavaScript may share initial syllables, but they are not closely related.
It's possible to achieve a great deal in JavaScript, but a clear definition of the requirements is necessary. Do you mean the buttons should be dynamically generated? If so, yes, this is possible in JavaScript. What would drive the process?
Also, i would like to have dynamic action on it, for example, when the button is pressed, fill a string of text into other items(text field) within the page. Without more detail its not possible to make any specific suggestions. For example, I certainly would not want to create 50+ individual dynamic actions relating to different buttons.

How to restart the i pad after eraseing the contents

Hey does any body know how to restart the Ipad after the contents were erase with out being back up? Now the Ipad won't let get to home screen

If you erase the contents of the iPad, you have to start all over again, just like you did when you took it out of the box and turned it on for the first time. It is like the device is brand new again. You will get to a point in the set up where you have the option of restoring from a backup (iTunes or iCloud) or set it up as a new device. If you don't have a backup, then you do have to start all over again. It doesn't "go to the home screen" until after you set it up again.
If you are not seeing this behavior on your iPad, restart the iPad and try again.
If that doesn't answer your question, what exactly are you trying to do? And what about it isn't working for you?

How to restart the mac like the first time you use it?

how to restart the mac like the first time you use it?

Surefire way is by completely reinstalling the OS after erasing the Macintosh HD boot volume.
I think there's a way to coerce the Setup Assistant to run once again like on First Start, but requires erasing a couple of files in the drive. Don't know which ones right now.

How to set the JMX Engine parameter in Process Administation?

Hi, All,
I installed OBPM10gR3 over WLS 10gR3 clusting environment. OBPM Engines started successfully.
There is one admin server running on localhost: 10101, one manager server running on localhost:10103, another managed server running on localhost:10105.
I wonder how to set the JMX Engine configuration in Process Administration. How about the port? 10101 or 10103,10105? How about the Credentials, weblogic as the default user?
I'm appreciated you can share me the JMX Engine configuration in Process Administation for weblogic clusting. Thanks in advance.
Best Regards,
Bill

Hi, All,
Here is more detail error when I set the JMX host/port to weblogic admin server/port, actually the BPM server is started, and the status of engine in process administation is started and I can run the process normally. I don't know why there is "null" url:

If you have a rescue email address (which is not the same thing as an alternate email address) set up on your account then you can try going to https://appleid.apple.com/ and click 'Manage your Apple ID' on the right-hand side of that page and log into your account. Then click on 'Password and Security' on the left-hand side of that page and on the right-hand side you might see an option to send security question reset info to your rescue email address.
If you don't have a rescue email address (you won't be able to add one until you can answer 2 of your questions) then see if this user tip helps : https://discussions.apple.com/docs/DOC-4551
e.g. you can try contacting iTunes Support : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page, then Account Management , and then try Apple ID Account Security
