Hi guys!
I create a class in c#, to convert from "x" document to pDF.
The app works correctly in my local pc, but when migrate to the server I get
this error:
System.Runtime.InteropServices.SEHException (0x80004005): External component
has thrown an exception.
at
cppu.defaultBootstrap_InitialComponentContext(Reference<com::sun::star::uno::XComponentContext>*

ini_file, IDictionaryEnumerator bootstrap_parameters)

I use OpenOffice 3 and install OpenOffice.org_3.4.1_SDK.

I tried diferents solutions, but nothing worked.
string officePath = installPath + @"\soffice.exe";
string officeParams = "-headless -nologo -nofirststartwizard
-terminate_after_init -invisible";
string unoParams = "-accept='pipe.....'";

I forgot install some else in server? Such as Apache?
Please I need hel urgent
