Hola, alguien conoce la causa del siguiente error: *2018-08-06 14:35:44,194

- Está ocurriendo al intentar subir un archivo, ya sea un logo de una 
comunidad o colección, o un documento de un ítem, adjunto el stack trace de 
del mismo, ya revisé los archivos dspace.cfg y bitstore.xml y en ninguna 
parte me dice algo sobre el almacenamiento temporal de archivos cargados, 
solo el maximo de carga, los permisos de las carpetas estan correctamente 
configurados (chmod 765) y el propietario es el usuario tomcat7, ¿que mas

- It is happening when trying to upload a file, either a logo of a

Re: [dspace-tech] Mirage2 & xmlui "file not found" error

[Tim Donohue]

Hello Sorin,

If you need further help, I'd recommend sending along more information to
this list about your build environment.  You said you are using Ubuntu
18.04 and DSpace 6.  But, what version of Java are you using (java
-version)? What version of Maven (mvn -v)?  What version of Ant (ant
-version)? Is this DSpace 6.0, 6.1, 6.2 or 6.3?

Oftentimes, build issues have something to do with invalid/incorrect
dependencies.  So, it's possible you are using either an unsupported
version of Maven or Java.

Take a close look at the versions of Java, Maven, etc that are listed on
the DSpace 6 installation guide:
https://wiki.duraspace.org/display/DSDOC6x/Installing+DSpace

 I checked and I have git installed. Will look later into supported
 versions and will check that I have what's needed.
 I thought that with the command mvn package -Dmirage2.on=true there's
 no need to install manually the prerequisites. I didn't install any of 
 them.
 I will also look into the links you gave me and come back with
 results.

 Thanks again.

Re: [dspace-tech] Mirage2 & xmlui "file not found" error

[Sorin Solomon]

Actually, it didn't.
Nothing worked. None of the things others did in previous posts on the same 
subject.

At the moment, pretty much lost. 
Any help would be greatly appreciated.

Thanks in advance.

 Hi Sorin,

 To me, this sounds like a possible build issue with the Mirage 2 
 theme.  You might want to double check some of the warnings/notes here 
 about building Mirage 2. 


 https://wiki.duraspace.org/display/DSDOC6x/Mirage+2+Configuration+and+Customization#Mirage2ConfigurationandCustomization-ThebuildprocessandenablingMirage2
  

 For example, Mirage 2 has its own prerequisites listed there (for 
 example, you need a more recent version of Maven and you must have Git 
 installed)

 Additionally, there are some other tips / hints from others who've had 
 build issues with Mirage 2 in the past.  See this "Common build issues" 
 section:

 https://wiki.duraspace.org/display/DSDOC6x/Mirage+2+Configuration+and+Customization#Mirage2ConfigurationandCustomization-CommonBuildIssues
  

 If you are still encountering issues, I'd recommend giving us more 
 information about your build environment (Operating system, version of 
 Java, version of Maven, etc) on this mailing list.  Hopefully others here 
 could help figure out what the issue may be.

 Tim

[dspace-tech] XSLT, XPath, and XQuery Functions available for Dspace (theming)

[Vusani Mutshinya]

Good day,

I am theming our implementation of Dspace, have done a lot. Working through 
a tutorial in this link 
https://wiki.duraspace.org/pages/viewpage.action?pageId=19006017#app-switcher , 
I have managed to get the Community list to expand and collapse.
Although the tutorial uses character I went a step further and used images 
which works well on the front page and the "community-list" page. However, 
if I select a community with sub-communities; the images appear as broken 
links in the sub-communities list.

I have an xsl algorithm I want to employ to make the only appear in the 
front and communities-list pages (see attached code snippet). 



 
 
 
 
 
 
 
 

I want to use xsl test fuction combined with either the 
base-uri()
or 
document-uri()

functions to get the current page URL, if the page URL contains the word "
*handle*" I will know the user has selected a particular community, so the 
image for expanding and collapsing the sub-community should not be 
displayed.

So my question then is, does Dspace have it's own equivalent of the two 
functions above or is there a list of xsl functions specific to dspace?

Many thanks
~Vusani
