Extract the war/ear and search the method names in the classes

Question

Hi,
I have implemented search function for methods in the class files in the physical path presented jars,
using url classloader am loading class and getting class object then using reflection API am getting declared methods.
but when i try to search more jars am getting stack over flow error.
since am using recursive function.
example code
ArrayList l_alClassNames = new ArrayList ();
RuleITClassLoader classLoader = new RuleITClassLoader();
Map l_mapMethodDetails = new HashMap();
m_mapPackageInformation = new HashMap();
ArrayList l_alMethodnames = new ArrayList();
boolean flage = false;
JarInputStream l_objJarInputStream= null;
try{
l_objJarInputStream = new JarInputStream(new FileInputStream (p_sJarpath));
JarEntry l_objJarEntry;
while(true) {
l_objJarEntry=l_objJarInputStream.getNextJarEntry ();
if(l_objJarEntry == null){
break;
String l_sPackagename ="";
if (l_objJarEntry.getName ().endsWith (IServiceAdministratorConstants.FILE_TYPE_CLASS)) {
String l_sClassName = l_objJarEntry.getName().replaceAll("/", "\\.");
l_sClassName = l_sClassName.substring(0, l_sClassName.length()-6);
Class l_objClass = classLoader.loadClass(p_sJarpath,l_sClassName);
if(l_objClass!=null){
l_sPackagename= l_objClass.getPackage().getName();
l_sPackagename = l_sPackagename.replaceAll("\\." , "/");
Method[] l_arrayMethods = null;
try{
l_arrayMethods = l_objClass.getDeclaredMethods();
}catch(NoClassDefFoundError exException){
/*m_objLogger.log(ILoggerConstants.SERVICEADMIN_WEBAPP, CLASS_NAME,
"getClasseNamesInPackage", "Error occured while l_arrayMethods ",
exException, ILoggerConstants.SEVERITY_WARN);*/
}catch(StackOverflowError StackOverflowError) {
l_sClassName = l_sClassName.substring(l_sClassName.lastIndexOf("."));
l_sClassName = l_sClassName.substring(1, l_sClassName.length());

l_objArguments.setArgumentName(l_sArgumentName);
l_alArguments.add(l_objArguments);
l_alArgumentsType.add(argCnt,l_objParameterTypes[argCnt].getName());
String l_sMethodAliasName = constructMethodAliasName(l_alArguments, l_arrayMethods[b_MethodsIndex].getName());

flage =true;
l_alMethodnames.add(l_objMethods);
if(l_alMethodnames.size()>0){
l_mapMethodDetails.put(l_sClassName, l_alMethodnames);
l_alMethodnames = new ArrayList();
if(l_mapMethodDetails.size()>0 && flage){
l_alClassNames.add(l_mapMethodDetails);
l_mapMethodDetails = new HashMap();
if(l_alClassNames.size()>0 && flage)
m_mapPackageInformation.put(l_sPackagename, l_alClassNames);
l_alClassNames = new ArrayList();
I need some solution to fix.
I need implemete the search methodsnames for war files and ear files.
kindly help to implement on this

Hi,
Is it possible to send across the .ear file across as an attachment, so that I can test it out at my end ASAIC and let you know the results.
Thanks & Regards
