>Today I had an issue with an application that I wrote. The application makes heavy use of InfoPath forms and routes them around to people via Windows Workflow Foundation. The whole application is written on MOSS of course. The application has been extensively tested and I have never seen the error that has occured before.
Part of the solution goes through an approval stage and once that stage has been completed the form is moved over to another document library in a separate site. For some reason this failed, the error was pretty cryptic “Unknown Server Error Number : D:” showed up in my exception handling.
I have some theories on what happened but first of all I wanted to get the solution working again and on to the next stage so that people could get using it again. So I though no worries I’ll just copy the InfoPath from the one library to another. So I set to work and used the built in move content functionality.
However when I looked at the file in its new destination it didnt look like an InfoPath form just a normal xml file. The workflow had automatically started but displayed that horrible “Error Occured” I looked at the logs and could see that when the workflow was trying to parse the form it threw an error unable to find BOM (Byte Order Mark)……..
So the SharePoint move/copy function seems to convert the xml file to another format which is not the same used by InfoPath.
I thought well I better write a little utility which uploads this file with the right encoding. So taking another utility that I wrote I sent to work. Now at the moment I dont have the code to hand and will update this post when I go, I might even upload the utility though it should have quite a few caveats of use attached to it.
Basically the code does this:-
Start the utility with site url with sub-web url, give it a list name, file name and tell it what the source encoding is and the target encoding.
The code snippet for uploading and encoding is the following:-
class InfoPathFileUploader : System.Object
private string m_sSPPath = “”;
private string m_sListName = “”;
private string m_sFilePath = “”;
private System.Text.Encoding m_encodeSource = Encoding.UTF8;
private System.Text.Encoding m_encodeTarget = Encoding.Unicode;
internal InfoPathFileUploader(string sSite, string sList, string sFilePath)
m_sSPPath = sSite;
m_sListName = sList;
m_sFilePath = sFilePath;
internal InfoPathFileUploader(string sSite, string sList, string sFilePath, System.Text.Encoding source, System.Text.Encoding target)
m_sSPPath = sSite;
m_sListName = sList;
m_sFilePath = sFilePath;
m_encodeSource = source;
m_encodeTarget = target;
public bool DoUpload(bool bOverwrite)
bool bSuccess = false;
Trace.TraceInformation(“Starting Upload (Overwrite:” + bOverwrite.ToString() + “)”);
bool m_bOverwrite = bOverwrite;
List listErrors = new List();
Uri uriSite = new Uri(m_sSPPath);
using (SPSite site = new SPSite(uriSite.OriginalString))
using (SPWeb web = site.OpenWeb(uriSite.LocalPath))
SPList listInfoPath = web.Lists[m_sListName];
if (listInfoPath != null)
string sFileUrl = “”;
string sFileName = “”;
//reset all variables
sFileName = “”;
sFileUrl = “”;
Trace.TraceInformation(“Reading File: ” + m_sFilePath);
fileInfoPath = System.IO.File.OpenRead(m_sFilePath);
filecontents = new byte[fileInfoPath.Length];
fileInfoPath.Read(filecontents, 0, (int)fileInfoPath.Length);
Trace.TraceInformation(“Converting File: ” + m_sFilePath);
sFileName = System.IO.Path.GetFileName(fileInfoPath.Name);
if (fileInfoPath == null)
throw new System.IO.FileLoadException(“Failed to read file contents into buffer”);
//check to see if destinationfolder url has a leading /
sFileUrl = “/”;
sFileUrl = sFileUrl + listInfoPath.RootFolder.ServerRelativeUrl + “/” + sFileName;
Trace.TraceInformation(“Uploading File to Sharepoint: ” + sFileUrl);
spFileInfoPath = listInfoPath.RootFolder.Files.Add(sFileUrl, fileunicodecontents, m_bOverwrite);
throw new System.IO.FileNotFoundException(“File failed to load into SharePoint”, sFileName);
bSuccess = true;
spFileInfoPath.Item[“Title”] = sFileName;
Trace.TraceInformation(“Successful Upload: ” + sFileUrl);
catch (System.IO.FileNotFoundException fileex)
Trace.TraceError(“FileException during upload: ” + fileex.Message + ” ” + fileex.StackTrace);
listErrors.Add(“Upload Failed (FileNotFound): ” + fileex.FileName);
catch (System.IO.DirectoryNotFoundException direex)
Trace.TraceError(“DirectoryException during upload: ” + direex.Message + ” ” + direex.StackTrace);
listErrors.Add(“Upload Failed (DirectoryNotFound): ” + m_sFilePath);
catch (Microsoft.SharePoint.SPException spex)
Trace.TraceError(“SPException during upload: ” + spex.Message + ” ” + spex.StackTrace);
listErrors.Add(“SPException: ” + spex.Message + ” ” + sFileName);
//display if any errors occured
if (listErrors.Count >= 1)
foreach (string error in listErrors)
Trace.TraceError(“Errors whilst uploading: ” + error);
catch (ApplicationException appex)
catch (Exception ex)
The utility runs and using the System.IO.File.OpenRead() opens the file Reads the file into a byte then the clever bit. The code uses System.Encoding.Convert(Encoding.UTF-8, Encoding.Unicode, byte) and outputs the converted byte.
This converted byte is then used and uploaded into sharepoint. The first time I ran it the file uploaded and after checking the properties and adding in the url to the infopath form template and file type (this is from memory). The form library reckonised the InfoPath form.
I restarted the workflow and it started working.
The encoding adds on to the front of the file the Byte Order Mark which seems to be striped by SharePoint when moving the file around. The file is also converted into UTF-8 when InfoPath uses UTF-16.
Updated (02 May 2008)
A little update to the utility when I originally ran this yesterday to fix the error it all seemed to be working well. My solution uses another InfoPath form which references these InfoPath forms reading out of it the Title property. The utility does not update the Title property. The only way that I could update the Title property was using SPFile.Item[“Title”]=”Title” and doing a SPFile.Item.SystemUpdate() a normal SPFile.Item.Update() does not update the Title property.
Further to this if the utility is run against the file again once its been converted from UTF-8 to Unicode then it will corrupt the file. I will be looking at updating the code to try and detect the Byte Order Mark and make an informed decision on the encoding conversion.
Like I say I will post the utility but hopefully this will help someone else if they run into the problem.
When a search crawl occurs an error is put in the crawl log.
“A word breaker was not found for the given language. Check your current language settings and ensure that search supports the current language. If the problem persists, reinstall search.”
The fix can be found here:-
Ah well found the fix and will document it here in case anyone else has a problem.
So the word breaker files are all found in the registry here:-
Under the registry key for each of the languages there is a value called
StemmerDLLPath and WBDLLPathOverride
For the English (United Kingdom) and English (United Status) languages these values were set to the following 8-3 path names:
So at the command prompt I typed in the following:-
dir /x C:\PROGRA~1\MICROS~2\12.0\Bin
Guess what the following line appeared:-
07/04/2008 13:27 3,976,520 NATURA~2.DLL naturallanguage6.dll
So updated the registry entry with NATURA~1.dll to NATURA~2.dll and restarted the Office and Windows Search. Performed a Full Crawl and finally a number of successful crawls entered the crawl logs.
This dll seems to handle a number of Languages including French, German, Dutch, Hebrew, Spanish and Italian.
Basically this issue happened on our QA environment when we were doing some testing. We racked our brains as to what changes have been made and couldnt think of a reason. Then after the problem was fixed we realised that the machine has been restored using TrueImage and this must have been the cause of the change in 8-3 filename!
>I have a number of development environments for different clients. Anyway I started some work for myself on one of the old machines and thought I better get this up to date and install WSS SP1 and MOSS SP1.
Simple .. Yeah!? I should have checked things out on the machine before I started. I have performed the upgrade on a number of machines with no problems. However there this time I did the normal install WSS v3 SP1 and then run the SharePoint Config Wizard… the wizard ran and then throw an error. I clicked on the link and it showed an error trying to start the Office Search.
I check the Office Search and yes it was unable to login. I went into services and updated the account name and password. Re ran the wizard and it failed again, this time resetting the account back the previous account. SharePoint holds this setting and reapplies the account details so using stsadm -o osearch -action start I applied the new farmaccount and password. This fixed the Office Search service which started successfully.
Reran the wizard to perform the upgrade and it failed again.
Looking at the psconfig logs showed that there was now a problem with the SharePoint WSS Search. I used stsadm -o spsearch -action stop to clean things up and then ran stsadm -o spsearch -action start using the new account and password credentials. It complained about the database not being empty. So after deleting the database, the command was run again.
Each time this was run an error happened saying that the search could not be started due to invalid login. I thought well I will try the upgrade and see what happens. Again the upgrade failed.
Looking on the web I found a link to http://geekswithblogs.net/hinshelm/archive/2007/12/13/installing-windows-sharepoint-services-3.0-service-pack-1-sp1.aspx
Where people were having similar issues this lead me to the idea of running the upgrade process using psconfig.
So going on to the command prompt I ran psconfig -cmd upgrade -inplace b2b this failed and required that the force flag is set because the upgrade has failed.
Run psconfig -cmd upgrade -inplace b2b -force, still the upgrade failed though looking into the upgrade.log file which lives in the HIVE12\logs. In the logs the same error about the SPSearch showed which said that the login was invalid. I started to think that this might be down to the fact that SP1 has been applied but the search process is unable to login due to issues with fact that the binaries are expecting an upgraded database but this hasnt occured yet.
From this thought I decided to stop the SPSearch and then do the upgrade:-
- doing an stsadm -o spsearch -action stop this when run asks if you want to delete all the indexes, say yes.
Then re-ran the psconfig -cmd upgrade -inplace b2b -force command.
After a while the command completed successfully! Hurrah.
Now to sort out the SPSearch function, this was solved by running stsadm -o spsearch -action start -farmserviceaccount [account] -farmservicepassword [password]
The SPSearch started successfully!
Anyway I hope that will help someone.
