Anything on the previous mail and
*Also i tried the setting up Cas Pool based on descriptor file using below
code... when i increase the number of threads from 1 i get following errors*
public class MyApplication {
private CasPool mCasPool;
private AnalysisEngine mAnalysisEngine;
public MyApplication()
{
//get Resource Specifier from XML file
XMLInputSource in = new XMLInputSource("MyDescriptor.xml");
ResourceSpecifier specifier =
UIMAFramework.getXMLParser().parseResourceSpecifier(in);
//Create multithreadable AE that will
//Accept 3 simultaneous requests
//The 3rd parameter specifies a timeout.
//When the number of simultaneous requests exceeds 3,
// additional requests will wait for other requests to finish.
// This parameter determines the maximum number of milliseconds
// that a new request should wait before throwing an
// - a value of 0 will cause them to wait forever.
mAnalysisEngine = UIMAFramework.produceAnalysisEngine(specifier,3,0);
//create CAS pool with 3 CAS instances
mCasPool = new CasPool(3, mAnalysisEngine);
}
// Notice this is no longer "synchronized"
public void analyzeDocument(String aDoc) {
//check out a CAS instance (argument 0 means no timeout)
CAS cas = mCasPool.getCas(0);
try {
//analyze a document
cas.setDocumentText(aDoc);
mAnalysisEngine.process(cas);
doSomethingWithResults(cas);
} finally {
//MAKE SURE we release the CAS instance
mCasPool.releaseCas(cas);
}
}
