JSP toolkit check if document exist (chapter 2)

Hy guys,

I would need to check in a jsp page if a document exists or not. I
would not want to do it with a previous DASL query; I would like to do
it in the jsp page.

I found this very interesting old thread in your mailing list [1] and
I would like to know if it is actually possible to have something
similar to the following snippet working:

<c:set var="testdoc"
value="${repository.fetchDocument['content/e-overheid/home1.xml']}"/>

<c:if test="${empty testdoc }">
NULL
</c:if>

Re: JSP toolkit check if document exist (chapter 2)

Hi Enrico,

It should be possible to retrieve a document (and also content en metadata)
like this:
<c:set var="document"
value="${repository.fetchDocument['/content/path/to/document/document.xml']}"
/>

When the document is not available, an error will be thrown. It's possible
to catch the
fetch statement in a <c:catch> for example. Then it should be possible to
check for
an empty document.

Regards Dirkjan

how to extract PDF text into property?

Hi everybody,

When performing a DASL query I am retrieving also some PDF's from my
binaries folder. I would like to provide to video also an extract from
the text in the PDF's. Is that possible?

In the extractors.xml of my repository I already set the PDFExtractor.
Reading the [1], my understanding that is not a real extractor, it is
more an indexer. Therefore it will index the text contained in the PDF
but it will not extract it as a property.

>From [2] it seems that it is not possible to extract the text from PDF's.

I think it should be possible to do it somehow ... can you give me
some suggestions?
Thank you very much for your attention!

Re: JSP toolkit check if document exist (chapter 2)

Hi Dirkjan,

Thank you very much for the suggestion! I actually did not know of the
existence of the catch tag in the core JSTL. Good to know for the
future :-)

Handling the potential exception I manage to do what I wanted.

Regards,
Enrico

Re: how to extract PDF text into property?

Hello Enrico,

I think you should try to hook in the pdf extractor just like the
property extractors. The problem with the normal pdf (and also xml
extractor) is that they take place *after* the save, where extractors
that set properties are before the save. It is unlucky that they both
are called extractors.

Anyways, I think you should dive into the property extractors, and see
if you can do something similar for pdf's. For me it has unfortunately
been to long to know this

Regards Ard

Re: how to extract PDF text into property?

Hi Ard,

Thank you very much for your answer.

Only to be a 100% clear about the situation ... my understanding is
that there is no PDF (real) extractor for hippo CMS 6 at the moment.
So if I wanted to implement what I need I should write the extractor
myself. Does that correspond to the truth?

Thank you,

Re: how to extract PDF text into property?

there is a pdf extractor, but this one only runs during indexing, and
not for storing a property as you seem to want

Expanding the folderview

Hi,

I would like to expand the folderview by default. Currently users always
have to open a folder and then another folder inside that one. We would like
to get rid of those extra clicks. Perhaps by firing one or more events after
initialization? I have trouble finding the proper spot to make these
changes.

Regards,

Wouter Zelle
