batch file error

[SIRINEM]

hi,
when i execute my batch file i get this error
error:Unable to find or load main class gr.seab.r2rml.beans.Main

Hi,
Please give some more information, including: operating system, java version, shell command you are trying, and log file output.

[SIRINEM]

my os is windows 7 professional, java version:Eclipse IDE for Java Developers (Neon.1a Release (4.6.1)), mysql version is 5.7.9.
and this is how i executed the batch file

Could you try running the batch file from folder r2rml-parser-0.8-alpha? It looks like the problem is that parameter -cp "./*;./lib/*;" in the batch file does not find any jars to add in the classpath.

thank you it works.
now i got the tool in the target folder, how do i begin to transform my tables into rdf?

[nkons]

Great that it now works.

Can you make the question more specific please?

If not at this point, see the Getting Started and Examples pages in the wiki, and try to reproduce the iswc example (example no. 5).

Some familiarity with relational databases and rdf is required, though. You could start with the book Materializing the Web of Linked Data, especially Chapters 2 (Deploying Linked Open Data: Methodologies and Software Tools) and 4 (Creating Linked Data from Relational Databases).

I created two tables in mysql and i want to transform them into rdf but i don't know how to start after i got the tool in the target folder.

[nkons]

I'm afraid the question is still too vague. Could you please be more specific: e.g. do you have a sql schema, sql queries that extract the data from the database, an rdf skeleton to populate? How do these look like?

hello,
I have the same problem and running directly in the "r2rml-parser-0.8-alpha" folder does not work too. I'm on linux Could you help me to run the program.

cordially

@youcoul Could you try running the batch file from folder r2rml-parser-0.8-alpha? (see comment above)

[youcoul]

I run from the r2rml-parser-0.8-alpha file, but it does not work, nothing happens

[nkons]

Maybe this is a permissions problem, could you verify it is executable (and if not, run a chmod +x) ?

[youcoul]

yes it is executable, But when I execute nothing happens.
