How to create namespace filter for KM

[Former Member]

Introduction
This weblog is a step by step guide to creating a namespace filter for your KM repostiory.
Step 1

Create a empty portal project using wizard inside NWDS

Step 2

Select the project that was created above and using KM wizard to create the KM namespace filter.

Step 3

Open up your java file for filter. In my case it is ExcludeTemp.java. It should look following.

package com.ust.namspcfilter;import com.sapportals.wcm.WcmException;import com.sapportals.wcm.repository.ICollection;import com.sapportals.wcm.repository.IResourceList;import com.sapportals.wcm.repository.filter.AbstractNamespaceFilterManager;import com.sapportals.wcm.repository.filter.INamespaceFilter;public class ExcludeTemp implements INamespaceFilter {  private final INamespaceFilter predecessorFilter;  ExcludeTemp(INamespaceFilter predecessorFilter) {    this.predecessorFilter = predecessorFilter;  }  public IResourceList filter() throws WcmException {    // TODO Implement filtering (remove resources from the list)    return this.predecessorFilter.filter();  }  public ICollection getCollection() throws WcmException {    return this.predecessorFilter.getCollection();  }    }
Step 4

Now, you need to modify the method filter(). This is where you code to hide certain files/folder by looking at their name. In my case i am hiding files with certain file extension (.back, .tmp, ... )

public IResourceList filter() throws WcmException {  // Implement filtering (remove resources from the list)  String filename;  IResourceList workingResourceList = this.predecessorFilter.filter();  IResourceListIterator workingResourcelistIter =   workingResourceList.listIterator();  while (workingResourcelistIter.hasNext()) {   IResource currentResource = workingResourcelistIter.next();   if (currentResource != null) {    if (!currentResource.isCollection()) {     filename = currentResource.getName().toUpperCase();     if (filename.indexOf("~") >= 0      || filename.endsWith(".MDB")      || filename.endsWith(".MDL")      || filename.endsWith(".RQL")      || filename.endsWith(".RQS")      || filename.endsWith(".BAK")      || filename.endsWith(".TMP")      || filename.endsWith(".LDB")      || filename.endsWith(".LOG")      || filename.endsWith(".CSV"))      workingResourcelistIter.remove();    }   }  }  return workingResourceList; }
Step 5

Deploy your component to your portal and assign it the repository that needs to be filtered

Step 6

The changes in above step should affect the KM immediately but if it doesn't then restart your portal.
BAM!!! You got yourself a namespace filter
