Detach library using Jdapi

Question

Hi,
I am using JDAPI to detach libraries from the forms(10g). I am using the following code to detach library. The system run successfully without error but the libraries were not detached and it is still attached in the forms.
private static void destroyLibrarys(FormModule formModule){
JdapiIterator formAttachedLibraries = formModule.getAttachedLibraries();
while (formAttachedLibraries.hasNext()){
AttachedLibrary formAttachedLibrary = (AttachedLibrary)formAttachedLibraries.next();
System.out.println("Library: " + formAttachedLibrary.getName());
formAttachedLibrary.destroy();
Has anyone faced such problem and resolved it? Please help me in this issue.
Regds,

Hi Nandakumar,
i faced the same problem and got the following solution, not very pretty but working. First i count the libraries to instantiate a string array, then write the names of the libraries to the array. For each element in the array i refresh the iterator for the AttachedLibraries after destroying one library. I used this method to change the library names to lowercase and to replace some libraries in the migration process.
The String switchLibrary is of format oldPllName:newPllName, oldPllName:newPllName; you may ignore this.
* Get a list of all attached libraries
* Destroy the attached library and attach it again with new name
* @param fmb - FormModule we are working on
private void reAttachLibraries(FormModule fmb) {
writeLogln("");
writeLogln("Attach libraries");
String switchLibrary = getMigrationProperties().getProperty("migration.process.plsqllibrary.switch");
String[] switches = null;
String[] oldPll = null;
String[] newPll = null;
if (!isNullOrEmpty(switchLibrary)) {
switches = switchLibrary.split(",");
oldPll = new String[switches.length];
newPll = new String[switches.length];
for (int i = 0; i < switches.length; i++) {
String[] tmpArray = switches[i].split(":");
oldPll[i] = tmpArray[0].toLowerCase();
newPll[i] = tmpArray[1].toLowerCase();
JdapiIterator attLibItr = fmb.getAttachedLibraries();
int libCounter = 0;
while (attLibItr.hasNext()) {
AttachedLibrary lib = (AttachedLibrary)attLibItr.next();
libCounter++;
attLibItr = fmb.getAttachedLibraries();
String[] libNames = new String[libCounter];
libCounter = 0;
while (attLibItr.hasNext()) {
AttachedLibrary lib = (AttachedLibrary)attLibItr.next();
String attLibName = lib.getName().toLowerCase();
if (!isNullOrEmpty(switchLibrary)) {
for (int i = 0; i < oldPll.length; i++) {
if (attLibName.equals(oldPll[i])) {
attLibName = newPll[i];
writeLogln("Library "+oldPll[i]+" replaced with "+attLibName);
libNames[libCounter] = attLibName;
libCounter++;
for (int i = 0; i < libNames.length; i++) {
attLibItr = fmb.getAttachedLibraries();
AttachedLibrary lib = (AttachedLibrary)attLibItr.next();
lib.destroy();
for (int i = 0; i < libNames.length; i++) {
AttachedLibrary lib = new AttachedLibrary(fmb, libNames[i]);
writeLogln("Attached Library: "+libNames[i]);
