B4J Question Error opening word doc -

[focus330]

Hello

I'm trying to open a word doc file with this code:

Sub OpenDocx As JavaObject
    Dim in As InputStream = File.OpenInput(dir, filename)
    Dim document As JavaObject
    Try
    document.InitializeNewInstance("org.apache.poi xwpf.usermodel.XWPFDocument", Array(in))
    Return document
    Catch
        fx.Msgbox(Null,LastException.Message,"Error")
        Log(LastException.Message)
    End Try
End Sub

I Have this error: java.lang.ClassNotFoundException: org.apache$poi xwpf$usermodel$XWPFDocument

I'm using jdk 11.0.1 but i have the same error using 1.8.0_141
Libraries JPOI ( 5.0 ) and XLUtils ( 1.14) are checked. B4j version is 9.0
I also add the dependencies for poi 5.0 into libraries and also into addlibraries.

Searching with browser I find that may be ooxml jar not updated. If yes how to repair ?

What can I do ?
Thanks for your help.

Regards
S.Viola

There is an invalid space between poi and xwpf. It should be: poi.xwpf

What a mistake ! Thanks.
But now, I have another error

It seems that the documents ( I tried more than one ) are not readable. I try rewriting with word in version word 95, word 6.0 but the error is the same.
Note that a test function with WebView with the same docs was positive until yesterday in the morning. Yesterday I tried installing Office last edition to see if problems with poi will be resolved. Now I uninstall office.
Have Ito declare some jar ? Attached the complete log

try rewriting with word in version word 95, word 6.0

This can't work. XWPFDocument can only open docx files.

Best if you reproduce it in a small project + the docx file and upload it.

Also with docx I have the same error. Now I try a small project as suggested. See you later. Thanks

 

[focus330]

Yes. With a new project It works. Open docx and also save function. Now I have to add a print function and then 'copy' to my master program.
Thanks.

For information:
The documents I had to use are 'doc' made with Windows95. Rewriting into a 'docs' version they lost tags , fields or union, formatting and others. Not only but someone of them becomes corrupted.
Then it seems to me that poi to populate fields isn't the best solution also because I don't know how to print them.
Then I have to decide what is better:
1 use Tibco reports replacing doc models Good solution but I have to build 15 reports.
2 generate from the app an excel file with data (or at least an Mdb but I have to verify if B4j supports access drivers ) to use externally printing union. Very simple but user has to work as now and I have not a complete control from the app.

Best regards
