OpenKM 5.0-Beta scanner problem

Hi,

I'm trying to deploy scanner project which I build myself, but in the end I have problem. In compilation process everything is all right (except pom.xml warning about java-plugin.jar) but when I deploy this project and run scanner (by clicking icon in GUI) and open java console I have this error:
Code: Select all
Java Plug-in 1.6.0_20

Missing inlcuding some libraries while compilation jar ? Take a look in original jar for included libraries.

Hi,

I checked jar files and comparison is like this:

My jar file missing:
- /META-INF/OKM.DSA
- /META-INF/OKM.SF
- all /ws folder

I also checked pom.xml and in version 4.1 is dependency

<dependency>
<groupId>com.openkm</groupId>
<artifactId>ws-client</artifactId>
<version>2.1</version>
</dependency>

but in 5.0 this is missing.

Thanks a lot.

Mateusz

Has anybody got a solution to this?

I've got the same problem:
Code: Select all

And the compile of the scanner was successful - no errors / warnings!!!
--> mvn clean install
--> produced 2 jars - scanner-jar-with-dependencies.jar and scanner.jar
--> I then copied both of these to src/openkm/main/webapps
--> compiled this (again with mvn clean install) - (successful - only some gwt depreciated warnings)
--> copied reultant OpenKM.war to jboss-4.2.3.GA/server/default/deploy
--> OpenKM starts fine, when clicking on the scanner button the console gives the above error
(which is weird because scanner-jar-with-dependencies.jar contains the org/apache/http/entity/mime/content/ContentBody.class !!!)

What am I doing wrong - I must have recompiled / ran this thing etc 100+ times!! V.E.R.Y. frustrating (which is worsened by the COMPLETE LACK OF DOCUMENTATION regarding the scanner applet - even though this is proudly mentioned in the feature list!! The scanner applet is even broken on the demo page (http://demo.openkm.com/OpenKM (which has been 503 unavailable for the whole day now)), reporting a scanner class not found error.

Regards
Glenn

Try replacing scanner-jar-with-dependencies.jar file name to scanner.jar and only copy this to OpenKM folder.

Tell me if it solves the problem ? because on UI I'm sure we call scanner.jar file.

In developer guide we don't explain anything about scanner and uploader modules, until today nobody has been interested on them.

OK, but how can I get this jar file? My compiled jar still doesn't work. Maybe I use other tools then you. Maybe you can provide some how to?

You can compile the Scanner applet just with:
Code: Select all
$ mvn clean package
But you also need to sign the jar. Check for jarsigner man pages for more info (or Google).
