Document Indexes for Lucene in PowerAqua

In the file multi_indexproperties.xml

there are two lines of code:

<INDEX_GLOBAL_PATH>/Applications/apache-tomcat-5.5.23/webapps/poweraqualinked/LuceneIndexes/</INDEX_GLOBAL_PATH>

<INDEX_INFO_FOLDER>./indexListInformation/indexkmiweb07-philips/</INDEX_INFO_FOLDER>

which is referenced by:

./PowerAqua-decompiled/lib/poweraqua/indexingService/creator/MultiIndexServiceConfiguration.java

---------------

list = configuration.getElementsByTagName("POWERMAP");

setPowermap(Boolean.valueOf(list.item(0).getFirstChild().getNodeValue()).booleanValue());

list = configuration.getElementsByTagName("VIRTUOSO");

setVirtuoso(Boolean.valueOf(list.item(0).getFirstChild().getNodeValue()).booleanValue());

list = configuration.getElementsByTagName("REMOTESPARQLVIRTUOSO");

setRemoteSPARQLVirtuoso(Boolean.valueOf(list.item(0).getFirstChild().getNodeValue()).booleanValue());

list = configuration.getElementsByTagName("ONTOLOGY_INDEX_DB");

setDb(list.item(0).getFirstChild().getNodeValue());

list = configuration.getElementsByTagName("ONTOLOGY_INDEX_DB_LOGIN");

setLogin(list.item(0).getFirstChild() != null ? list.item(0).getFirstChild().getNodeValue() : new String());

list = configuration.getElementsByTagName("ONTOLOGY_INDEX_DB_PASSWORD");

setPassword(list.item(0).getFirstChild() != null ? list.item(0).getFirstChild().getNodeValue() : new String());

list = configuration.getElementsByTagName("INDEX_GLOBAL_PATH");

setIndex_global_path(list.item(0).getFirstChild() != null ? list.item(0).getFirstChild().getNodeValue() : new String());

NodeList indexes = configuration.getElementsByTagName("INDEX_INFO_FOLDER");

System.out.println("Number of indexes is " + indexes.getLength());

this.indexList = new ArrayList();

for (int i = 0; i < indexes.getLength(); i++)

{

String indexFolder = indexes.item(i).getFirstChild() != null ? indexes.item(i).getFirstChild().getNodeValue() : null;

MultiOntologyIndexBean bean = new MultiOntologyIndexBean(indexFolder);

getIndexList().add(bean);

}
 ----------------

It fails if INDEX_GLOBAL_PATH or INDEX_INFO_FOLDER is called.. but it contains a null or nothing specified in the tag  ... I think this triggers new String() which triggers a stack trace
