Accessing global custom attributes in WebCenter Portal 12c

Global Attributes can be declared to share variables and information between all the Portals.

Out of the box, one of the attributes is the wcSessionTimeoutPeriod responsible for the session timeout. My friend Daniel already blogged about
accessing this on his blog entry.

Way of accessing in EL is still working as following



If you want to use Java API, one way to use


But if you are concern about performance, it’s not best practices to use evaluate EL in the java class. It is better to use OOTB API to access this. in 12c you can use following way

WCApplicationContext wcAppCtx = WCApplicationContext.getCurrentInstance();
WCApplication wcApp = wcAppCtx.getApplication();
WebCenterType wcMeta = wcApp.getApplicationConfig();
CustomAttributes customAttr = wcMeta.getCustomAttributes();

This will work in 12c.

Fusion Middleware Security – Search user in AD using OPSS

Oracle Platform Security Services (OPSS) provides enterprise product development teams, systems integrators (SIs), and independent software vendors (ISVs) with a standards-based, portable, integrated, enterprise-grade security framework for Java Standard Edition (Java SE) and Java Enterprise Edition (Java EE) applications.

OPSS provides an abstraction layer in the form of standards-based application programming interfaces (APIs) that insulate developers from security and identity management implementation details. With OPSS, developers don’t need to know the details of cryptographic key management or interfaces with user repositories and other identity management infrastructures. Thanks to OPSS, in-house developed applications, third-party applications, and integrated applications benefit from the same, uniform security, identity management, and audit services across the enterprise.

OPSS is the underlying security platform that provides security to Oracle Fusion Middleware including products like WebLogic Server, SOA, WebCenter, ADF, OES to name a few. OPSS is designed from the ground up to be portable to third-party application servers. As a result, developers can use OPSS as the single security framework for both Oracle and third-party environments, thus decreasing application development, administration, and maintenance costs.

Products which use OPSS

  1. Oracle WebLogic Server
  2. Oracle ADF
  3. Oracle WebCenter
  4. Oracle SOA
  5. Oracle Entitlement server
  6. Oracle WebService Manager
  7. Java Authorization for Containers (JAAC)

OPSS provides an integrated security platform that supports:

  • Authentication
  • Identity assertion
  • Authorization, based on fine-grained JAAS permissions
  • The specification and management of application policies
  • Secure storage and access of system credentials through the Credential Store Framework
  • Auditing
  • Role administration and role mappings
  • The User and Role API
  • Identity Virtualization
  • Security configuration and management
  • SAML and XACML
  • Oracle Security Developer Tools, including cryptography tools
  • Policy Management API
  • Java Authorization for Containers (JAAC)


OPSS Architecture




Now moving further with use of OPSS with ADF/WebCenter application. We have features , so that user can search user from LDAP using name, last name or email. How can we achieve that.

Something like below image.





User click on Search User-This will search in Active directory user mapped with WebLogic security provider.



In Search box, enter Name, Last Name or email and click on Search icon .


Or try with email




So you can add some more custom parameters with that and search it. Now we will focus how we did that.

Following is code to search with parameter in OPSS


    public List<userProfileId> getUserDetails() {
        if (this.userDetails.size() == 0) {

            if (peopleName != null) {
                try {

                    JpsContextFactory ctxFactory = JpsContextFactory.getContextFactory();
                    JpsContext ctx = ctxFactory.getContext();
                    LdapIdentityStore idstoreService =
                        (LdapIdentityStore) ctx.getServiceInstance(IdentityStoreService.class);
                    IdentityStore idmIdentityStore = idstoreService.getIdmStore();
                    //  User user = idmIdentityStore.searchUser(peopleName.getValue().toString());

                    if (peopleName.getValue() != null) {
                        SimpleSearchFilter simpleSearchFilter[] = new SimpleSearchFilter[3];

                        simpleSearchFilter[0] =
                            idmIdentityStore.getSimpleSearchFilter(UserProfile.LAST_NAME, SimpleSearchFilter.TYPE_EQUAL,
                        simpleSearchFilter[1] =
                        simpleSearchFilter[2] =
                            idmIdentityStore.getSimpleSearchFilter(UserProfile.NAME, SimpleSearchFilter.TYPE_EQUAL,

                    ComplexSearchFilter cf =
                        idmIdentityStore.getComplexSearchFilter(simpleSearchFilter, ComplexSearchFilter.TYPE_OR);
                    /* Creating Search Parameters with Complex Search Filters */
                    SearchParameters spUser = new SearchParameters(cf, SearchParameters.SEARCH_USERS_ONLY);
                    SearchResponse searchResponse = idmIdentityStore.searchUsers(spUser);
                    while (searchResponse.hasNext()) {
                        System.out.println("Count " + searchResponse.getResultCount());
                        UserProfile up = (UserProfile);
                        System.out.println("User Profile:" + up.getPrincipal());
                        name = up.getName();
                        email = up.getBusinessEmail();
                        UserID = up.getLastName();
                        UserName = up.getUserName();
                        userDetails.add(new userProfileId(name, UserID, email, UserName));

                    //    uprofile.setUserDetailss(userDetails);
                    /*  UserProfile up = user.getUserProfile();*/

                } catch (JpsException e) {

                } catch (IMException e) {
                } catch (Exception e) {

        return userDetails;

That’s it. You can use this following ocde in pure ADF or WebCenter Portal applications easily. Do let me know your thoughts.

Performance tuning of Jdeveloper 12c

Very frequent we get issues of JDeveloper hangs.Then you need to close JDeveloper and restart. if you are developing and debugging, this problem occurs more frequently.This post tell how to make your jdeveloper with better performance.

Jdeveloper –

1) Go to MW_HOME \jdeveloper\ide\bin\ide.conf and increase the Max heap size (Xmx).

//Set this option depend on your system configuration.I have 16gb ram, I prefer to set this.
AddVMOption -Xms2048M
AddVMOption -Xmx4096M

2) Go to MW_HOME \jdeveloper\jdev\bin\jdev.conf and set the following parameters

// Increase your MaxPermSize
AddVMOption -XX:MaxPermSize=1024M

//Adds a memory monitor which helps in check current heap used by jdeveloper

AddVMOption -DMainWindow.MemoryMonitorOn=true

//ADD the following JVM options towards the end of file
AddVMOption -XX:+UseStringCache
AddVMOption -XX:+OptimizeStringConcat
AddVMOption -XX:+UseCompressedStrings
AddVMOption -XX:+UseCompressedOops
AddVMOption -XX:+AggressiveOpts
AddVMOption -XX:+UseConcMarkSweepGC
AddVMOption -DVFS_ENABLE=true
AddVMOption -Dsun.java2d.ddoffscreen=false
AddVMOption -XX:+UseParNewGC
AddVMOption -XX:+CMSIncrementalMode
AddVMOption -XX:+CMSIncrementalPacing
AddVMOption -XX:CMSIncrementalDutyCycleMin=0
AddVMOption -XX:CMSIncrementalDutyCycle=10


3 ) Disable the SVN versioning system that is built into JDeveloper.Uncheck the checkbox for Subversion for example support for GIT

4) Reduce ON-Save and AFTER-Save Actions
Go To Tools >> Preferences >> Code Editor >> Save Actions
Remove “Build After Save”



After that, Please restart jdeveloper.Your jdeveloper will give better performance
