Scripting was an advanced feature introduced in OpenKM 5.0 that enables administrators to execute some BeanShell scripts in folders, fired on every notified event ( for example uploading documents ). This feature has been overseed by Automation, which help you to do the same things with a few mouse clicks. For compatibility reasons there is also an Automation task where you can put a BeanShell code. This replaces the old way of enabling scripting.



Nota clasica.png OpenKM uses BeanShell. For more information point your browser to http://www.beanshell.org/intro.html.


BeanShell is a small, free, embeddable Java source interpreter with object scripting language features, written in Java. BeanShell dynamically executes standard Java syntax and extends it with common scripting conveniences such as loose types, commands, and method closures like those in Perl and JavaScript.

You can also execute a custom script when OpenKM starts or stops. To do so, just create a start.bsh (and / or stop.bsh) file in $TOMCAT_HOME. For example, we use this feature to create a complete environment (create custom users, register property groups, register workflow) each time the OpenKM demo is restarted.

Scripting in automation view

In Automation Scripting execution, there're several variables what are directly injected in scripting environment what can be use.

List of variables what can be used directly

Variable Status Description
systemToken The system token
node Involved node (NodeDocument, NodeFolder, etc.. )
uuid Object unique identify
file Only available when uploading or updating a new document content.
userId The user id
nodeUuid deprecated Object unique identify
nodePath deprecated Object path

To test these variables simply can execute the script:

print(uuid);


Examples

Purge all users trash

import com.openkm.api.*;
import com.openkm.core.*;
import com.openkm.bean.*;
import com.openkm.module.db.stuff.*;
 
String token = DbSessionManager.getInstance().getSystemToken();
 
for (Folder trash : OKMFolder.getInstance().getChildren(token, "/okm:trash")) {
    print("Trash: " + trash.getPath()+"<br/>");
 
    for (Folder fld : OKMFolder.getInstance().getChildren(token, trash.getPath())) {
        print("About to delete folder: " + fld.getPath() + "<br/>");
        OKMFolder.getInstance().purge(token, fld.getPath());
    }
 
    for (Document doc : OKMDocument.getInstance().getChildren(token, trash.getPath())) {
        print("About to delete document: " + doc.getPath() + "<br/>");
        
        if (OKMDocument.getInstance().isLocked(token, doc.getPath())) {
            OKMDocument.getInstance().forceUnlock(token, doc.getPath());
        }
        
        OKMDocument.getInstance().purge(token, doc.getPath());
    }
 
    for (Mail mail : OKMMail.getInstance().getChildren(token, trash.getPath())) {
        print("About to delete mail: " + mail.getPath() + "<br/>");
        OKMMail.getInstance().purge(token, mail.getPath());
    }
}

Update repository stats

import com.openkm.core.*;

new RepositoryInfo().run();

try {
    if (reports.isDirectory()) {
        for (File rep : reports.listFiles()) {
            int id = ReportDAO.createFromFile(rep, FileUtils.getFileName(rep.getName()), true);
            String sql = "insert into OKM_PROFILE_MSC_REPORT (PRP_ID, PRP_REPORT) values (1, " + id + ")";
            LegacyDAO.execute(con, sql);
        }
    }
} catch (Exception e) {
    e.printStackTrace();
} finally {
    LegacyDAO.close(con);
    HibernateUtil.close(hbmSession);
}

Show jBPM mail configuration

import org.jbpm.*;

print("Templates: " + JbpmConfiguration.Configs.getString("resource.mail.templates") + "<br/>");
print("From: " + JbpmConfiguration.Configs.getString("jbpm.mail.from.address") + "<br/>");
print("Host: " + JbpmConfiguration.Configs.getString("jbpm.mail.smtp.host") + "<br/>");

Reset user document size

import com.openkm.dao.bean.cache.*;

import com.openkm.api.*;

for (int i=0; i < 10; i++) {
  String path = "/okm:root/fld_" + i;
  OKMFolder.getInstance().createSimple(null, path);
  OKMPropertyGroup.getInstance().addGroup(null, path, "okg:technology");
}

Show number of documents, folders and size from a given path

import com.openkm.bean.*;

ContentInfo ci = OKMFolder.getInstance().getContentInfo(null, "/okm:root/path/to/folder");
print("Folders: " + ci.getFolders() + "<br/>");
print("Documents: " + ci.getDocuments() + "<br/>");
print("Size: " + FormatUtil.formatSize(ci.getSize()) + "<br/>");

Get path by UUID

import com.openkm.api.OKMRepository;
String path = OKMRepository.getInstance().getNodePath(null, "b99f7973-4b90-457a-a2d0-cf2090ba995d");
print(path);

Compact documents with size=0

Find all documents with size=0 and compact history of versions to latest

import java.util.*;

            print("Doc UUID: " + uuid + ", Process Definition: " + procDef.getId() + ", Process Instance: " + procIns.getId());
        }
    }
}

Purge all folders into some parent

That script purge all folder into some parent, without previously moving files to trash. The purge action is a non recovery action what remove definitivelly the objets from OpenKM repository. Use it with care.

import org.hibernate.*;
import com.openkm.dao.*;
import com.openkm.dao.bean.NodeFolder;
import java.util.*;
import com.openkm.api.OKMFolder;

Session session = null;
found = true;	
try {
    String sql = "from NodeFolder nf where nf.parent='aa08b392-0117-4b29-af9a-c4419ba6cab6'";
    while (found) {
        session = HibernateUtil.getSessionFactory().openSession();
        Query q = session.createQuery(sql);
        q.setMaxResults(100);
        found=false;
        List fldList = new ArrayList();
        for (NodeFolder fld : q.list()) {
            found= true;
            fldList.add(fld.getUuid());
        }
        for (String uuid : fldList) {
            try {
	        OKMFolder.getInstance().purge(null, uuid);
            } catch (Exception e) {
                print(e.getMessage()+"<br/>");
            }
        }
    }    
} catch (Exception e) {
    print(e.getMessage());
} finally {
	HibernateUtil.close(session); 
}

Count all children subfolder

Count all children folders - and subfolders into, recursion - into first level folder ( okm:root children folders ).

import com.openkm.api.*;
import com.openkm.bean.*;
import org.hibernate.Session;
import org.hibernate.Transaction;
import com.openkm.dao.HibernateUtil;
import org.hibernate.HibernateException;
import org.hibernate.Query;

class Util {
    public int childCount(String uuid)  {
        String qsUUIDList = "select uuid from NodeFolder nf where nf.parent=:parent";
        Session session = null;
	 	Transaction tx = null;
        int value = 0;
        List uuidList = new ArrayList();
        try {
            session = HibernateUtil.getSessionFactory().openSession();
            tx = session.beginTransaction();
            Query q = session.createQuery(qsUUIDList).setCacheable(true);
            q.setString("parent", uuid);
            uuidList = q.list();
            HibernateUtil.commit(tx);
            value = uuidList.size();
            print(value);
        } catch (HibernateException e) {
            HibernateUtil.rollback(tx);
        } finally {
            HibernateUtil.close(session);
        }
        
        for (String childUuid : uuidList) {
            value = value + childCount(childUuid);
        }
        return value;
    }
}

Util util = new Util();
for (Folder fld : OKMFolder.getInstance().getChildren(null, "/okm:root")) {
    print(fld.getPath()+"->"+util.childCount(fld.getUuid())+"<br/>");
}

Recursive character renaming

Rename a character in all folders or documents from some initial path.

// Recursive renaming & to -
import com.openkm.api.*;
import com.openkm.bean.*;

void findNodePathHelper(String path) {
    for (Folder fld : OKMFolder.getInstance().getChilds(null,path)) {
	//print(fld.getPath().substring(fld.getPath().lastIndexOf("/")).replaceAll("&","-"));
	if(fld.getPath().contains("&")) {
		OKMFolder.getInstance().rename(null, fld.getPath(), fld.getPath().substring(fld.getPath().lastIndexOf("/")).replaceAll("&","-"));
	}
	for (Document doc : OKMDocument.getInstance().getChilds(null, fld.getPath())) {
		//print(doc.getPath().substring(doc.getPath().lastIndexOf("/")).replaceAll("&","-"));
		if(doc.getPath().contains("&")) {
			OKMDocument.getInstance().rename(null, doc.getPath(), doc.getPath().substring(doc.getPath().lastIndexOf("/")).replaceAll("&","-"));
		}
	}
	findNodePathHelper(fld.getPath());
    }
}

findNodePathHelper("/okm:root");
