Error while making iview with visual composer

Question

I am trying to make an iview usign visual composer.
In the document that i have for making the iview , it says that when you have the bapi list you need to drag and drop the bapi to the empty iview pane . When i do so it gives me the following error ...
"Portal request failed
(com/sap/mdi/ObjectFactory)"
What do i do ?
Would appreciate a prompt help!
thanks again for making me move ahead
I had a conversation with a parson on the forum named Venkat . I am posting the same for other people in the forum to understand what exactly is my problem and how much have we explored .

Hi Venkat ,
I tried to do so research on the problem and it is being talked about in a thread on the forum . They ask to refer to the sap note 765461 to resolve the mdi reference . In the note they ask you to refer the installation guide of the installed version of EP . I have EP 6.0 SP2 . The installation guide says the following ...
7.1.2 Adding References
To enable some of the features in the portal environment, add references to reference file.
To add a reference:
1. With a text editor, open the file:
Windows: <installation drive>:\usr\sap\<SAP J2EE instance name>\j2ee\<instance
number>\cluster\state\services\file\work\managers\reference.txt
Unix: /usr/sap/<SAP J2EE instance name>/j2ee/j2ee_<instance number>/
cluster/state/services/file/work/managers/reference.txt
2. Look for the line:
reference service:eisconnector library:jco
3. After the line mentioned in previous step, add the following in a new line:
reference service:eisconnector library:com.sap.mdi
4. Save your changes and close the file.
5. Delete the file:
Windows: <installation drive>:\usr\sap\<SAP J2EE instance name>\j2ee\<instance
number>\cluster\state\services\file\work\managers.bin
Unix: /usr/sap/<SAP J2EE instance name>/j2ee/j2ee_<instance number>/
cluster/state/services/file/work/managers.bin
6. Restart the SAP J2EE Engine. See Starting the SAP J2EE Engine [Page 60].
7. Restart the SAP J2EE Engine again.
I did the same ....but now my server is not starting . By chance i didn't keep a bakup of the file which they asked me to delete .
Now what do i do ?
I think i am stuck up badly here .
EVERYBODY IN THE FORUM PLEASE HELP
I am not sure how a thing that is mentioned in the installation guide cannot work !

Deepak,
It is not that bad. By deleting you are recreating that managers.bin file during startup based on the reference.txt and library.txt (recollecting from my memory). This could also happen if there is a typo or some special characters in the reference.txt
I don't know what J2EE patch you are at, but after PL22 you can actually add the reference using the "add reference" command from the administrator console.
could you please send the error you are getting? To revert back the simplest thing is removing the line you have added and restart.
Hope this helps.

Venkat ,
I am using J2EE engine 6.20 SP2 .I tried to get the server started by the following two methods
1) I removed my entry in the reference.txt file and then start the engine by running go.bat from the required path .
2) I got the original file managers.bin which i deleted and then placed in the required path and restarted the server
Both the options didn't work .
I am not getting any error when i restart the server. When i run the batch file go.bat it starts the console and shows me the various managers loading . After it shows the Clustermanager loading , it stops and gets stuck .
Not sure what should i do now .Is reinstallation the only solution ?
Is there a solution from the administrator console ?

Deepak,
No you don't need to re-install. Try the following.
1. First start the state controller by runing go.bat in the following directory.
/usr/sap/xxx/j2ee/cluster/state/go.bat
You get the message waiting for cluster manager.
2. start the server in a different window
/usr/sap/xxx/j2ee/cluster/server/go.bat
You get the message waiting for cluster manager
3. Start the dispatcher
/usr/sap/xxx/j2ee/cluster/dispatcher/go.bat
Please let me the know the error messages.
You can chat with me between 10:00 - 11:00 PM US EST.

Answer 1

People ,
   I tried to do what venkat suggested . Infact I had mailed him the snapshot of the screen when i start the state controller as he suggested . For other people in the forum this is what is happening . When i start the state controller it displays an error and then the window closes immediately . I have managed the screen shots somehow and in those i could find two messeges in the begining and the end which could be useful for debugging the problem ...they are
1) [DBMS]: ID3004:DB file header do not match exception .
com.inqmy.services.dbms.server.interfaces.DatabaseException: Error while opening database ...
2) ID000544: Error statrting service dbms. DBMS service not started properly due to: Errro while opening database
[Framework -> criticalShutdown] Service dbms startup error !
After the state controller window closes i run the server in a different window and i get a message waiting for the cluster manager as suggested . Now i start the dispatcher and i get the same messege there as well ie waiting for the cluster manager .
What is to be done now . Is this information sufficient to suggest me something ? Please let me know if you require any other information .
