Local J2EE engine needed for NWDS

Hi Everybody,
I am new to NWDI. We want to use NWDI to make changes to ESS applications. The NWDI is installed with the Portal installation on the server.
I installed the Netweaver Developer studio on my Laptop. I didnu2019t install a local J2EE engine only the JDK. My question is do I need a local J2EE engine before I can start using the NWDI. I want to create a track and import the development into NWDS.
Edited by: Stoffel Erasmus on Aug 25, 2009 3:48 PM

Stoffel,
It's not necessary to have local j2ee engine.
to setup access to NWDI from NWDS go to windows-preferences - SAP J2EE Engine - select remote and give the host and port
go to widnows - preferences - java development infrastructure - development configuration - give the sld path
go to DTR perspective - create a DTR client by giving some name and DTR url and workspace
go to Development Configurations perspective - right click on Local Development- Import configuration
Thanks

Need help getting local J2EE engine to run

Hello,
I have installed Netweaver Developer Workplace with MaxDB and a local J2EE engine.
I cannot figure out what all I need to do in order to have all the proper pieces of J2EE engine running locally so I can deply and run some simple servlets/JSPs locally.
I have gone into Administrative Tools|Services and made sure that SAPJ2E_00 and SAPJ2E_01 are both set to Automatic.
Even after doing that and rebooting I still don't see the J2E node as green in the management console. So I rightclick on it and choose start.
When I do that, a bunch of dos(console) windows open and run some commands and after awhile one of the nodes under J2E on management console shows up as green but the other one never does.
Is there some documentation somewhere that shows how to do this locally? I don't want to do it on a server yet.
Thanks in advance for any help.
David

Siddesh,
Thanks for your reply. That was a helpful link in that it got me pointed in the right direction. I found a document that told me to look in the dev_jcontrol file.
There I found the following...
[Thr 2904] Tue Apr 12 09:42:30 2005
[Thr 2904] *** ERROR => invalid return code of process [bootstrap] (exitcode=66) [jstartxx.c 1433]
[Thr 2904] JControlExecuteBootstrap: error executing bootstrap node [bootstrap] (rc=66)
[Thr 2904] JControlCloseProgram: started (exitcode = 66)
[Thr 2904] JControlCloseProgram: good bye... (exitcode=66)
So I did a search in this forum for "exitcode = 66" and found a couple of posts. This one seems to be the most like what I'm experiencing
J2EE engine stopped running / WAS 6.40
Halfway thru that post it mentions checking the jvm_bootstrap.out file for errors. I did and it had the following in it:

Not quite sure what to do. Where do I check the database properties and how do I know which are wrong?
Also, in a subsequent post of that same thread it mentions running the following command in a command window:
dbmcli db_enum
I searched the sap install directory (c:usr) and its subdirectories for a file starting with dbmcli and couldn't find one. Is that installed automatically when you install NDS Workplace?
Any help would be greatly appreciated.
Thanks

How to install local J2EE Engine for NTW4 Dev Studio ?

We installed a full Web As 640 ABA+J2EE stack9 , and activated all the JDI components (DTR, CBS, CMS).
NOw we instaleld on local pc the Developer Studio and are trying to begin teh develop of java packages.
We are not able to activate the debug on the remote J2EE ENgine.
According the HelpOnline we should install a local J2EE Engine in order to be able to do debugging.
The problem is taht nowhere is written where to find out this software and how to install.
Anyone has some experience on that ?
Regards
G.

Hi Gianfranco,
I see. Then, you are right. You need a local J2EE Engine.
There is a guide how to install a Developer Workplace at:
http://service.sap.com/instguidesnw04 -> Installation -> Dev Env -> Inst. Guide - SAP NetWeaver Developer Workplace Stack x
Hope, that will help.
And I guess, the following might be of some help after you complete the installation: http://help.sap.com/saphelp_nw04/helpdata/en/92/fa369fb68e004598f246494665a49e/frameset.htm

How to install/start local J2EE engine in Netweaver Developer Studido

Hello,
I just installed NDS 2.0.11 and I'm having a heck of a time figuring out how to actually test my code.
Went thru tutorial for creating Calculator J2EE sample. When I get to step that describes how to deploy the EAR I get error below. I've gone into Windows|Preferences|SAP J2EE Enginee section thinking I could configure/start engine from there but I can't figure out what to do.
I've searched these forums and the NDS help files with no luck.
I didn't get any prompts during install asking me whether or not I wanted to install a local J2EE engine.
Has anyone run into this and do they know the answer. ANY help would be greatly appreciated.
Thanks!

RK,
Thanks for the link. It did help a little. I found some of the errors on that page and it helped me get past them.
The last issue I had run into was issue 1-13. So I created a new user on my laptop and gave it admin rights.
The install got a little further but now it's stuck again. Here are the messages from the install log:
SAPinst is getting started.
Please be patient ...
guiengine: no GUI connected; waiting for a connection on host TAGname, port 21212 to continue with the installation

ERROR Could not create DOM from control.xml

Any ideas?
I started the install process by running SAPinst.exe. When the installation window opened I chose

Thanks in advance for help!

Starting local J2EE engine from SAP MMC

I am trying to start my local J2EE engine using SAP MMC. However, when I select the start option, the DB no longer starts automatically. I can manually start the DB, select start, and the engine will start. Previously, I could select start and everything would just come up.
Can anyone tell me where the disconnect is occuring?

Hi,
If you have an add-in installation then you can try to stop the java system by stopping the java dispacther by stopping the j2ee process.You can just try restarting the java system using SMICM.You can check whether the data base services are set to auto start or need a manual start.
Reward points if helpfull.

How can I start local J2EE Engine in debug mode automatically?

Hello,
I thought there was a way to setup the local J2EE engine to automatically start in debug mode.
Right now, I have to start the engine, go into Studio and right-click on engine and choose "Enable debugging of process". This means that I have to wait for the engine to restart.
What I'm looking for is a system setting where I can tell it to automatically start in debug mode.
Thanks in advance for any help.
David.

Ivaylo,
Thanks for the quick reply.
Could you please elaborate on your instructions? I have started the Config Tool. Now I see the following tree structure:
+ cluster-data
   secure store
   UME LDAP data
I expand the cluster-data node and get this:
- cluster-data
    +Global dispatcher configuration
    +Global server configuration
    +instance_ID12345
Assumed that I should expand the instance node. When I do I get this:
    + dispatcher_ID1234500
    + server_ID123450
Again, I assumed I should expand the server node. This is where I get lost. I have no idea where to go next to set the debug configuration.
Can you please help?
Thanks
David.

SAP J2EE Engine configuration in NWDS 7.1

Hello everybody,
I would like to configure the SAP J2EE engine server (host and port) in NWDS 7.1.
In NWDS 7.0 I used to go in the Preference > SAP J2EE Engine and select "SAP J2EE engine is installed on a remote host" and enter the "Message server host" and "Message server port".
In NWDS 7.1, there is no "SAP J2EE Engine" in the preference and the only place where I found a field for J2EE engine was a local host only one.
How can I do in 7.1 what was able to do in 7.0?
Thanks in advance
François

Hi Fronis,
I feel you just installed NWDS CE 7.1. But there is a lenghty process to achive that. After installation of 7.1 in menu path goto help>software updates>link*(first option)>login to servicemarketplace>there are two options first select 1st after completion next select 2nd it will take long time(bcozz it will download nearly 1.7gb).
try this and let us know....

Local J2EE Engine Download?

Hi Experts,
I have been trying to download files for J2EE engines to install on my computer, so that I can deploy and run my applications locally. I have no luck with the SDN download section, so I went to SAP Service Marketplace instead. My version is NW2004s 7.0 SP09. Please anyone help with this, which files should I download. Are they
                             NW 2004s SR2 Developer Workplace 1 of 4,
                             NW 2004s SR2 Developer Workplace 2 of 4,
                             NW 2004s SR2 Developer Workplace 3 of 4, and
                             NW 2004s SR2 Developer Workplace 4 of 4 ?
If so, how can I get the MaxDB folder without having a DVD? Please guide me through this, and I would greatly appreciate your help.

Hi
Those are not the files for J2EE engine :
You can download from any one of the link given below
Download J2SE v 1.4.2_17 JRE which includes the JVM technology
http://java.sun.com/j2se/1.4.2/download.html
Also you would need Java Cryptography Extension (JCE) during installation. You can find at the bottow of the link
"MaxDB" you can download from www.service.sap.com/swdc

How to install local J2EE engine

Hi Experts,
I am trying to install the J2EE engine to my local PC in order to do development for WebDynpro.
Does anyone have any step by step procedure of doing this?
I have searched through the forum and found some threads, but I couldn't quite understand the steps and the files needed to do this instalation.
FYI, I have the complete SAP Netweaver instalation CD. Does all the instalation file available on these CDs?
Your help is highly appreciated.
Best Regards,
Fandi

Hi,
1.you can install only 32 bit engine on your system,since your system doesn't support 64 bit engine.
2.Check for available space in C:\.since your default installation drive will be C:.It should have minimum of 9GB space and your RAM should be 1GB minimum.
3.Install JDK .Run exe file of JDK.By default ,it will be installed in C:.Take latest j2sdk1.4.2_13.4.Set environment variables in Mycomputer-->properties>advanced--->enviroment variables.
Under user variable,add parameter JAVA_HOME with path of JDK.(c:\j2sdk1.4.2_13)
Under System variable,click path and add path of JDK at the end and give path till bin.(c:\j2sdk1.4.2_13\bin).
5.Then you have to downlaod the CD's for 32bit Java stack.Copy those files to your desktop and run sapinst.exe.

Can't start local J2EE Engine

In our company we have a large group of developers who all have Netweaver Developer Studio installed on their machines to do java development. They also have the local engine installed to deploy and test their code.
We're on version 7.0 (aka 2004s) SP9.
One of our developers has been working fine, then went to a week of training, has come back and now his engine no longer starts up locally - same computer that worked before.
Server1 turns green, but Server0 stays yellow. The error we see in the std_server0.out is as follows:
Failed to reserve 1610612736 (0x60000000) bytes before loading DLLs (error 8).
We have tried all of the following with no success:
- Restarting his computer
- Lowering the Max heap size using the ConfigTool (it was originally at 768, which has always worked in the past, but we took it to 512 just to see)
- Using the SAP Address Space Viewer, we tried the Rebase DLLs
Any other suggestions of things to try?
Thanks,
Jennifer

Hello Jenifer,
Markus Dohr set you on the right track. This issue is caused by memory fragmentation in result of the installation of hot fix from Microsoft. Unfavorable basis addresses of Windows system DLLs or DB Client DLLs fragment the address space of the JLaunch process. The Java VM fails to initialize because it cannot allocate enough contiguous address space for the configured amount of Java heap.
Before trying the solution try to prelod the DLLs as Markus suggested (Note 853696)
Solution
1. Use the ConfigTool to reduce the maximum heap size of the J2EE Engine node to allow the J2EE Engine to start.
2. Follow the procedure in SAP Note 129813 to analyze the JLaunch.exe process, to identify the offending DLL and to rebase it. From 640 SP14 on the DLL preload function can be used instead of rebasing, please read note 853696.
3. If the DLL cannot be rebased (due to Windows File Protection), please refer to note 664269 Rebasing DLLs under WFP or create an OSS/CSN message for the BC-OP-NT component.
Please also see note 664607 - Hot Fixes or patch sets with fragmenting DLLs.
NB: Do not delete server node 0!!! You could disable it, so it doesnt start, but do not delete it. If you want to run with only one node, delete server node 1.

Hello Cajuntank and welcome to the Palm forums.
Palm Desktop needs to be installed with the local administrator priviledge during the install of Palm Desktop, the HotSync Manager, the first HotSyn sync, and the installation of any third-party conduits on the desktop.

Cats Template got saved local but I need for Global

Hi all,
I have made change to my cats screen time line columns ( displaying only one column instead of 31 for a monthly profile ) and saved it as a template ( clicking on the top most corner of the time line)
The issue is, this template is loaded only from the Logged on person but not from any other Logged on persons .
I want to create a template that would be reflected in all the Logged on persons Globally ? can you please let me know how to achieve this ?
Thanks
Abhishek

with an html widget.
you can not achieve the result with html snippet widget, because you have no control over it.
... if we can figure this out it will be a breakthrough for having an effective navigation bar and a great timesaver for editing.
it can be done and it's a known debate between me and other whose like to hide iweb navbar and build their own text based navbar, here was my argument: http://discussions.apple.com/thread.jspa?messageID=8136472&#8136472
that said, it can be done when you have control over iweb, here are examples:
http://home.cyclosaurus.com/CyclosaurusBlog/Entries/2009/8/11Pieces_of3.html (note the drop down menu overlap other elements).
http://home.cyclosaurus.com/CyclosaurusBlog/Entries/2009/9/10iWeb_NavBarWidget.html
the examples were done with my widgets, so give apple feedback and ask for tools to build widgets and take controls: http://www.apple.com/feedback/iweb.html
