WebDynpro and J2EE Engine

Hi
If we develop a WebDynpro application, Is it possible to deploy it in any other web server.
Or SAP Web App server 6.40 is the only J2EE engine under which it has to run .
Regards
Bhanu

Hi Bhanu,
the simple answer is "no", you can't deploy/run Web Dynpro applications to/in other servers.
Hope that helps.
Regards
Stefan

Anybody explain ABAP client and J2ee engine?

There are client 000,001,066.
But for J2ee Engine the client is in a different way.
What is the relationship of User data between ABAP client and J2ee Engine?
and tell me some inside about client copy? I have read some docs of help online, I 'd like more tech fact.

Hello Shen,
First ground rule: ABAP stack can support mutiple clients while JAVA stack supports only one client at one given time. In terms of user master data you can have 1:1 relationship between ABAP client and corresponding J2EE client provided there is connection between ABAP and UME which normally is there as it configured during installation. So if a user exists in client X in ABAP you can also view it in client X of J2EE.
Regarding client copy what type of client copy are you asking about?
Regards.
Ruchit.

SAP J2EE Engine has stopped working suddenly

Hi,
I have only SAP J2EE stack in WebAs installed on a machine couple of months ago and all the while it was working fine.But suddenly one day (precisely monday)i see that J2EE Server node is not starting up. But the central instance (which has processes MsgServer.exe,Enserver.exe) has started sucessfully but not the server node instance.
I am getting the following error in the log file

I have't not changed any passwords of db users like SAPJ2EDB but i don't know why i am getting this error suddenly.
Can anyone throw light on this issue.
Thanks and Regards,

Hi Detlev,
The DB (SQL 2000) is started and i have verified through
Window service console and SQL Server Service Manager.
Even the Config tool (i.e offline tool) is throwing the following error message when started.

1)is it due to mismatch of the passwords of the user SAPJ2EDB in database and J2EE Engine and Securestore of config tool
2)is there some DB related problem ?
3)i think the problem is similar to this one
Netweaver's WebAS SDM process goes corrupt, exitcode=66
But the solution there is not so clear
4)After i changed the password both in the database as well as in configtool >Secure Tool>/jdbc/pool/J2E/password..but i am getting java.sql.SQLException: [DataDirect][SQLServer JDBC Driver][SQLServer]Invalid object name 'J2EE_CONFIG' this error.
Any idea on what needs to be done to fix this problem

WAS SP9 SR1 ABAP+Java Add in installation , j2EE engine is not running

I have completely installed SAP Netweaver SP9 SR1 WAS ABAP+JAVA addin and Installed XI completely. After few days j2EE engine stops running. I have applied the license after requesting from SAP Mareketplace and applied in WAS ABAP using SLICENSE transaction.
Issue faced
1. Tried to connect j2ee engine home page which is showing.
Dispatcher is running but no server connected.
Now I have removed the WAS J2EE installation and removed the client on which WAS j2EE engine installed. After doing this I tested the WAS ABAP which is running fine. Now I am again installing WAS Java addin. Which installed success fully and have seen the j2ee engine server page running. But proceeding further to install JAVA Dialog instance I am facing folloing issues
2. while installation step 8 and 9 as per SAP INSTANCE GUI .
3. And J2EE engine is again stopping.
Can any one help me to install J2ee dialog installation and resolving these issues.

Hi Anand,
J2EE Engine has a separate licensing mechanism. If the temporary license expires, the server will shut down every 30 minutes. You install a permanent license using Visual Administrator in service "Licensing Adapter".
In any case, a look into the log files of the engine can provide further information. They are found at
.../<SID>/<INSTANCE>/j2ee/cluster/server<n>/log
Kind regards,
Juergen Kremp

Anilkumar,
Still no luck. I am not using any complex data types and the developer studio and J2EE engine are both at SP09.
Is there anything special I must do when deploying to a remote J2EE engine? I am running NDS on Windows box and attemtping to deploy to an AIX box the J2EE engine. I can deploy with no problem a simple J2EE app like the Calculator example. I only receive this error when I attempt a WS deploy.

SSL on J2EE engine

Hi,
We are on Ep6 SP12 and we are making our portal available via internet. we have adapted IIS proxy and wanted to apply SSL. I'm little confused on number of SSL certificates I have to apply. Between Browser and J2ee engine I have IIS server.
Do I have to apply SSL between browser and IIS or is it sufficient if I apply SSL to J2ee engine??
Any suggestions or docs or ideas highly appreciated.
thanks,
Maya.

It depends on the level of encryption that you want. However, it is possible to have SSL terminate at the IIS proxy box and have the proxy send out requests in http to the portal.

Please suggest me.

Hi Kiran,
You need configure SLD and JCo destinations in your j2ee engine..
Check this [article |https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/c0c1d495-048e-2b10-babd-924a136f56b5] to create the SLD and JCo destinations.

JCO connection tab in disabled mode in sap J2EE engine/webdynpro/local/proj

Dear all,
I'm developing the simple webdynpro object using netweaver developer studio, but when i deploy it to sap J2ee engine and go there to set the JCO connection, I find the jco connectiuon tab in the diabled mode. I need to configure the new jco connection in order to run the project. Please suggest.
thanks,

Hi Anup,
You can find service "SLD data supplier" under server->services list.
Refer following links for configuring SLD and JCO connections:

Webdynpro J2ee engine ping failed

i am not able to ping the J2EE engine from Netweaver. the server responds if i ping from the windows command prompt

are you able to see the page for the following url 'http://hostname:50000' . if not you have to start the J2EE engine. and if J2EE engine is started and running, then you have to give the correct parameters in WebDynpro to connect to J2EE engine.

Can someone guide?

In the additonal error log it says-
Unable to compare host[px1db] and host[x900704] Throwable: java.net.UnknownHostException Throwable message: x900704: x900704
where px1db is my portal server and x900704 is my localmachine name.
I dont know why it says so ...In NWDS i have configured only px1db.
any thoughts.

J2EE engine shuts down and restarts....

Hi,
I am doing a scenrio using BPM with multiple parallel process. I am using a inbound file adapter for the incoming message to feed the BPM process. I have set 500 messages/per recordset.The process is stable when the message size is small but when the message size increases may be to 2MB,the J2EE engine collapses and restarts a certain period of time.
When I look at the incoming messages they seem to have failed at the BPM process. I am not sure what is causing the J2EE engine to collapse and restart...It works fine with less than 1MB incoming messages....Does it mean XI cannot support messages greater than 1MB? I know its absurd but this is very interesting..Checking the SMICM, I find the processes are all normal...

2) Restart the server using Visual Administrator
3) open up the configtool again to ensure that the settings you have set in the config tool are available
4) Now check whether the problem occurs again or not
regards & cheers
