Regarding JCO Creation

Hi,
We were trying to create JCO in a newly installed system and for a super admin user it was saying no authorization. So we just logged into Visual Administrator and added the user to Administrator group using Securoty Providers services. Now I am able to view the JCO list , but cannot create a new one or edit the existing one ( it is in display mode). Also when we tried the same thing using J2EE_Admin, the same thing happens. Even the logs saying Access denied,
Your suggession on this is highly appreciated
Kind Regards,
Vivek.

Hi,
Make sure that you have properly configure SLD and connection test to SLD should be successfull.
Thanks,
Akram

Problem regarding the creation of Table using CSS.

Hi ,
Here I have a Problem regarding the creation of Table using CSS.
In My Application i have a table with multiple rows(Rows are Dynamically added to the table).First i am setting the table with the following properties:
width:900px;
height : auto,
Overflow : visible,
Max-height: : 200px.
If I use above properties,I'm getting a table with 5 or 6 rows(height upto 200px).After that i am getting the Vertical ScrollBar.
The problem is when a table has many columns, Vertical and Horizontal Scrolls are coming at the time of setting the table. The table height is not Increasing dynamically.
How can i use "height" property in CSS? (I want the table height to be increased when the columns are more.)
Thanks & Regards

Hi Viswa,
You can try with a service entry in the portal host. Go to Windows system in path "c:\windows\system32\drivers\etc\services"
Add a entry - sapms<SID> 36xx/tcp where xx is the instance number of the R/3 message server (like - sapmsPRD 3600/tcp)
Hope it helps.

JCO creation takes long time

Hi,
There is some problem with our portal while creating JCo Connection.
It takes very long time to create new JCo connection on development server . If i create Jco connection of same applicationon on other server(Qlty, prod), it takes very less time than development.
I am facing this problem from last few weeks, before it was working fine.
Regards,
Jigar Oza

Hi,
If the JCO connection creation is taking long time on development compared qlty, prod servers then it may be due to various reasons;
1. The H/W , system performance may not good.
2. Web server applications may be hanging up due to insufficient buffer, speed;
3. The Network you are using may not fast;
So please chk all of them & get support from ur basis team;

Buttons not enabling for JCO Creation in SLD

Hi Experts,
When i logged in into my Webdynpro Content Administrator with administrative rights, all the button like Create JCo Destination, Maintain JCo Destination and Start assigned SLD are getting disabled expect Check SLD Connection Button.
Moreover, displaying a message : "Connection to System Landscape Directory (SLD) could not be opended successfully." at the bottom of the screen.
When i click on the Check SLD Connection Button and then Test Connection, it gives again the same message i.e "Connection to System Landscape Directory (SLD) could not be opended successfully."
Now, When i click on the Check SLD Connection Button and then Start SLD, SLD server is staring and running.
Another thing is, When i am starting my sld server from logging in into http://<hostname>:<port>/sld, SERVER status is running. I stopped it and again started, then it is starting, but giving an error message as:
"Failed to send start signal for complete cluster, SLD may still be stopped on other cluster nodes."
When saving any parameters like profile information, it is not saving and saying error as:"
Cannot save profile settings CIM_ERR_FAILED: Failed to initialize cluster notification sender."
My setting are correct in SLD Data Supplier in Visual Administrator. I had filled the host/port/user/password information for both "HTTP Settings" and "CIM Client Generation Settings".
It went worked well earlier, i come across this problem recently with my sld.
Another thing that i noticed is when i click on the "CIMClient Test" button, its getting an error message saying "Failed to Generate and Test CIMOMClient Object". But, ealier it came as successfull.
I have full authorization to use admin tools.
What might be the problem.
any help must be appreciated.

sunil kumar

Hi Sunil,
We just had this issue couple of days before, this has to do with the JMS Provider Authorization. We did the following steps to solve our issue:
I. Default security configuration of JMS resources is in place (this is by far the most common scenario) and named anonymous users have been created.
Change the mapping of the "clients" jms role as follows:
1. Start the Visual Admin
2. Browse the tree in the left pane
<SID> -> Server 0 -> Services -> Security Provider
3. The "Policy Configurations" tab should be selected by default on the right hand side
4. Select the "service.jms.default.authorization" node from the "Components" list (should be the nineth entry from the top down)
5. Select the "Security Roles" tab
6. Select the "clients" node from the security roles list
7. You should see on the right hand side "Security Roles" list in which the "guests" node is marked
8. Switch to edit mode by pressing the change button on top (pencil icon). The "Modify" button should now become active
9. Press the "Modify" button
10.Select the "all" entry from the "Security Roles" list. The "Groups" pane should show one entry named "Everyone"
11. Press the "Save" button
12. Restart the cluster so that JMS and applications using it can reliably reinitialize.
Check
Note 971249 - JMSServerSecurityException thrown accessing JMS resources
for more details.
Hope this helps!

JCO creation problem

Hi,
I have defined in SLD one WAS Java Server and one R3 system. I would like to define JCO to this R3. I can define JCO Single Server Connection (step 2 - connection type) - it is going ok, but I can define JCo for metadata while it required connection with load balancing. When i have checked out " Load-balanced Connection " type an exception occurred:

What's the Name and PWD in JCO Creation ?

Hello All,
 I want to create a JCo Connection.
These are the steps which I've followed :-
1. Logged on to the Portal with username and PWD.
2. Went to the WebDynpro Tab.
3. Clicked on Create JCo Connection
4. Entered the details :-
 NAME : Test_Meta_Data
 Client : 800
Note: I gave the client number of the SAP backend system . Is it right ?
5. J2EE Cluster : I have only one server in the DropDown and it's already selected.
So I choosed the next step.
6. Connection Type : DICTIONARY META DATA
7. Application Server Connection :-
 Message Server : Only one server I have in the DropDown and so I selected that.
8. Security :
 Use Method : USER / PASSWORD
 Name : sapuser
 PWD : server
 Confirm PWD : server
 SNC : OFF
9. Finish.
When I press Finish I'm getting a message :-
" failed to create a new JCo Connection Test_Meta_Data
Error while obtaining JCo Connection. "
Can any one help me in resolving this ?
Regards,
Deepu:k

Hi Deepu,
Firstly,
Yes, The details u enter while creating JCO connection are for the SAP system,
So Client, UserName, Password are for SAP system(Backend) you are creating JCO for.
Secondly, About the error u r getting,
Error says " failed to create a new JCo Connection Test_Meta_Data"
that means the SLD user has not sufficient authorization to create JCO.
In Visual Administrator, in SLD Data Supplier
You would have given SLD connection settings, there you have to give the user which has sufficient authorization(Admin authorizations) to create JCO connection..
Check the current user given in SLD Data Supplier.
Hopefully your problem will be solved.
Regards
Deepak

Run Time JCo Creation

Hi All,
 I have to create JCO at runtime. Based on the SAP client ID, user id,password and system number i have to create JCO. Predefined JCO configuration for a client number thru Portal, is not useful, because i don't know how many users will logon at a time? So, i wish to create JCO based on the user inputs at run time.
I used the following code to create JCO at runtime.
try {
 mConnection = JCO.createClient("sapclient",
 "userid","password",lanuage,"appserver name", "system number");
mConnection.connect();
}catch (Exception ex) { ex.printStackTrace();
 System.exit(1); }
After creating, i got all information like(username,appserver name,system number, etc.)
At this stage i got JCo connection name like 'mConnection'. My question is how to move to next step using mConnection?.
The JcoConnection contains some methods like mConnection.execute(parameter).
1. Is it possible to execute BAPI using JcoConnection created at runtime?
2. How to execute BAPI using JcoConnection created at runtime?
3. Is it necessary to create a model through the wizard in NWDS?
4. If i use execute() method, what are the parameters to be given?
Please help me.
Kind Regards,
S.Saravanan.

Regarding Thread Creation

Hello,
To create a thread in java there are two methods.
(1) by extending from thread class.
(2) by implementing runnable interface.
implementing runnable interface is the preferred method to create a thread because we still have the option to extend from any other class.
But does anybody know why java provides 2 methods for thread creation, why doesn't it provide only option 2 (i.e. by implementing runnable interface) when it is the preferred option.
Regards,
Sandy.

Though Runnable interface is preferred to create threads in Java,most programmers extends Thread class.As jschell would say, 'I am rather certain' that the opposite is true.
The reason behind of this is that you can have a clear logic of your code by using ThreadThat's not even true and it certainly isn't a reason to extend Thread rather than implement Runnable.
most of the system programming written in java used Thread class instead of Runnable interface .If you have some evidence on the point please produce it. The consensus of opinion on these forums has been the other way round for many years.

Regarding RFC creation

hi all,
after creation of RFC,we have to release the RFC or not.
regards,
subba reddy

Hi Subbareddy,
Yes you have to release the RFC after compeltion of creation.
After creation of RFC first import it into XI system and then test it once.If everything is working fine then you have to create a request for transporting this RFC from Dev system to QUALITY system.After creatiing the transport request then you can release the RFC with that transport request.With out releasing the RFC you can't move from Dev system to Quality system.
Plz close this post if you got the answer.
Regards,
Raju.
