I had configured webutil in linux server as per document. my basic cofiguration is
OS - Linux redhad(4.0)
Front End - Forms [32 Bit] Version 10.1.2.0.2
Now i had created form in that form i m using webutil when on test button i m calling
show_webutil_information (TRUE);
It is showing all the webutil information
But on another button i m calling
v_ole_excel := client_ole2.create_obj ('Excel.Application');
client_ole2.set_property (v_ole_excel, 'visible', 1);
it is not working and after that none of the push button & menu is working in runtime form.
So Please Guide us to resolve the problem.

Loading TUI files in Linux it's an issue that we have recently discovered and it did not made it yet to the known issue list. I'm not 100% sure but I believe a workaround to that problem would be to go and manually edit that tui file and remove those attributes that generates errors. You can begin with  ATTR_TITLEBAR_STYLE and then look if one of the following are in the tui file: ATTR_DS_BIND_PLOT_STYLE, ATTR_DS_BIND_POINT_STYLE, ATTR_DS_BIND_LINE_STYLE, ATTR_DS_BIND_PLOT_COLOR and delete them. Then try to load the tui file again.
On the other hand I think there is a workaround for your original problem: the predefined fonts (VAL_DIALOG_METAFONT) looks bad on Linux. I believe there is a way a user can change the underlying font and the size of a predefined font. In windows you can change it in the registry but in Linux you can define an environment variable: XAPPLRESDIR that points to a directory that should contain a file named cvi, a file where you can write font settings. Each line has to be of the following format: <appName>.<key>:<value>. If you want the settings you're writing to be persistent for all applications the put a "*"instead of the application name. 
The list of possible key is: appFont (NIAppMetaFont), menuFont (NIMenuMetaFont), dialogFont (NIDialogMetaFont), e​ditorFont (NIEditorMetaFont), messageBoxFont (NIMe​ssageBoxMetaFont).
The value have to be of the following form: <font family>-<font name>-<font size>
Here is the only line I have in the cvi file: *.dialogFont : adobe-helvetica-19
