Also, do you recall what rt29446.jar patch was for?

This could likely be already in 4.30 and if you have that version installed,
it would not be needed.

Thanks. I have progressed slightly, it appears that XEP is throwing the
error: Unexpected end of stream


XEP is invoked thus:


    Dim logger As XEPLogger = New XEPLogger(sDumpFileName)

    Dim conf As IConfiguration = New Configuration

    Dim formatter As IFormatter = conf.CreateFormatter(logger)

    Dim success As Boolean

    Dim sourceStream As System.IO.FileStream

    Dim outStream As System.IO.FileStream


    Dim sOutFileName As String = MakeOutFileName(FOPath)



      sourceStream = New System.IO.FileStream(FOPath,

      outStream = New System.IO.FileStream(sOutFileName,


      success = formatter.Format(sourceStream, MakeSystemID(FOPath),
"application/pdf", outStream)


    Catch ex As Exception

      Throw ex



      Warnings = logger.GetWarnings

      Errors = logger.GetErrors


      If Not (sourceStream Is Nothing) Then


      End If


      If Not (outStream Is Nothing) Then


      End If

    End Try


    If success Then

      Return sOutFileName


      Return ""

    End If


The error is trapped by the Try.Catch block. I know it is XEP throwing the
error because my dump of the XEP.Logger messages exists, therefore we are
getting past the two stream creates, and it is processing the FO file. The
outStream PDF file exists, but it is 0kb. I believe that this file is
created by this line:


outStream = New System.IO.FileStream(sOutFileName,


From the logger dump, it seems that the error relates to the outStream file.
XEP is able to process the FO that I am sending in but it appears to be
failing at the point that it tries to write the PDF output. I thought this
might be because Cliser does not have permissions to write to the file, but
the security settings on the PDF file created by the code above show that
SYSTEM user has Full Control, and it did indeed work a couple of weeks ago.
Cliser executes under the Local System account which should have the same
privileges as SYSTEM (I believe they are the same SID).


I have attached the following:


CliserService.exe.config: Unfortunately the time stamp on this file is
yesterday because I updated the LOG-FILE setting so that I could see if any
errors were being reported. I am fairly certain that this file has not been
updated since it was last working. As you can see, apart from the log file,
the only other setting that has been changed since the original install is
the JAVA-CLASSPATH, which was updated to point to the rt29446.jar file. I
have checked this path.


Cliserservicelog.log: log output from the Cliser service.

I think more information is required.


1. How are you running RenderX? Through your own API? through XEP
Assistant? Through command line?
2. You should post your complete setting in CliserService.exe.config
(and maybe check them) . has a path changed or java installation been
3. What is the full log not just the last few lines?

Subject: [xep-support] PDF output is not created


I'm having a problem with an XEP installation that has been working
previously but seems to be now having an issue.


The generation process seems to work OK in that there are no errors
reported, but the resulting PDF is 0kb in size. I have compared the log
output from a recent execution with one done a couple of weeks ago when it
was working fine. The only difference I can see is that the last few log
lines are missing from the recent one. These lines exist in the successful
log but not in the bad one:


event page-number 1

event page-number 2

event page-number 3

event page-number 4

closeState generate


The failed run stops at this line:


event output-format pdf


Can you give me any suggestions on why it might be falling over now? Cliser
is running under the System Account so I don't think it's file permissions.
