[Dspace-tech] Problem with uploading a file to the collection

[Shwe Yee Than]

Hi,

I'm new to Dspace. I've encountered 2 problems after the installation of Dspace 1.4.2.

The fist problem is I've got the following error message when I upload a file (.pdf) to the collection.

HTTP Status 500 -
---------------------------------
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.
exception

java.lang.NoClassDefFoundError
org.dspace.content.Bitstream.create(Bitstream.java:184)
org.dspace.content.Bundle.createBitstream(Bundle.java:362)

javax.servlet.http.HttpServlet.service(HttpServlet.java:803)
org.dspace.app.webui.filter.RegisteredOnlyFilter.doFilter(RegisteredOnlyFilter.java:98)

note The full stack trace of the root cause is available in the Apache Tomcat/5.5.23 logs.

The second problem is I can't access the Dspace Page (i.e., http://fsktm.geranium2.um.edu.my:8080/dspace) from any other PCs rather than the localhost. The following is my configuration for Dspace in the [dspace-source]/config/dspace.cfg file:


dspace.dir = /home/dspace/tomcat/webapps/dspace
dspace.url = http://fsktm.geranium2.um.edu.my:8080/dspace
dspace.hostname = fsktm.geranium2.um.edu.my

Can anyone help me to solve theses problems? I'm really appreciate for the helping hands.

Regards,
~Shwe~

fsktm.geranium2.um.edu.my:8080/dspace) from any other PCs rather
than the localhost. The following is my configuration for Dspace

Did you change this file after installation?
Did you make sure, these changes got reflected in
[dspace]/config/dspace.cfg?
ant install-cfg would be a means to do so.

dspace.dir = /home/dspace/tomcat/webapps/dspace

No, this should point to the dir where your assetstore, history
and so on lives. This should not be the same directory that is
exposed to the web. In case you installed it there, you should
change this before going productive. Common procedures expect
this to be separate. Especially any changes you might want to
make to the jsp frontend are far more easily done if you can
just wipe this directory and replace it with a new .war file.
If your bitstreams are in the same directory, that is not
feasable. Besides, there a probably security issues why the
programmers decided to keep both directories separate.

To come back to your question, this variable is never read
by a client and should not be the cause for not being reachable
from outside.

I never saw the ccTLD .my before, but as it is your valid domain,
thats looks fine.

I cant say much to this. It does not look like a DB permissions
issue although this method directly calls the BitstreamStorageManager
which in turn opens a DB connection, but if the problem was there,
then it would be notified as a SQLexeption, not an exeption.
I would go to the tomcat log as advised.
Or, I would change the logging level to info at least
in the log4j configuration.
Is the context you are working in valid?
Id est, are you allowed to upload to this collection?
I guess you would not get to the uplaod page if not.
No, sorry, no help from here.

Maybe, this gets solved automagically as soon as you solve the
dspace.dir issue. Your server might not be able to write the
.pdf file to a directory beyond webapps because of general
security constraints of the tomcat configuration. That would
make sense. So take care for the simple dspace.cfg stuff first
and you might be done.

Bye, Christian
