  • WebSphere Application Server EJB Optimization

    - by Chris Aldrich
    We are working on developing a Java EE based application. Our application is Java 1.5 compatible and will be deployed to WAS ND 6.1.0.21 with EBJ 3.0 and Web Services feature packs. The configuration is currently one cell with two clusters. Each cluster will have two nodes. Our application, or our system, as I should rather say, comes in two or three parts. Part 1: An ear deployed to one cluster that contains 3rd party vendor code combined with customization code. Their code is EJB 2.0 compliant and has a lot of Remote Home interfaces. Part 2: An ear deployed to the same cluster as the first ear. This ear contains EBJ 3's that make calls into the EJB 2's supplied by the vendor and the custom code. These EJB 3's are used by the JSF UI also packaged with the EAR, and some of them are also exposed as web services (JAX-WS 2.0 with SOAP 1.2 compliance) for other clients. Part 3: There may be other services that do not depend on our vendor/custom code app. These services will be EJB 3.0's and web services that are deployed to the other cluster. Per a recommendation from some IBM staff on site here, communication between nodes in a cluster can be EJB RMI. But if we are going across clusters and/or other cells, then the communication should be web services. That said, some of us are wondering about performance and optimizing communication for speed of our applications that will use our web services and EJB's. Right now most EJB's are exposed as remote. (and our vendor set theirs up that way, rather than also exposing local home interfaces). We are wondering if WAS does any optimizations between apps in the same node/cluster node space. If two apps are installed in the same area and they call each other via remote home interface, is WAS smart enough to make it a local home interface call? Are their other optimization techniques? Should we consider them? Should we not? What are the costs/benefits? Here is the question from one of our team members as sent in their email: The question is: Supposing we develop our EJBs as remote EJBs, where our UI controller code is talking to our EXT java services via EJB3...what are our options for performance optimization when both the EJB server and client are running in the same container? As one point of reference, google has given me some oooooold websphere performance tuning documentation from 2000 that explains a tuning configuration you can set to enable Call By Reference for EJB communication when they're in the same application server JVM. It states the following: Because EJBs are inherently location independent, they use a remote programming model. Method parameters and return values are serialized over RMI-IIOP and returned by value. This is the intrinsic RMI "Call By Value" model. WebSphere provides the "No Local Copies" performance optimization for running EJBs and clients (typically servlets) in the same application server JVM. The "No Local Copies" option uses "Call By Reference" and does not create local proxies for called objects when both the client and the remote object are in the same process. Depending on your workload, this can result in a significant overhead savings. Configure "No Local Copies" by adding the following two command line parameters to the application server JVM: * -Djavax.rmi.CORBA.UtilClass=com.ibm.CORBA.iiop.Util * -Dcom.ibm.CORBA.iiop.noLocalCopies=true CAUTION: The "No Local Copies" configuration option improves performance by changing "Call By Value" to "Call By Reference" for clients and EJBs in the same JVM. One side effect of this is that the Java object derived (non-primitive) method parameters can actually be changed by the called enterprise bean. Consider Figure 16a: Also, we will also be using Process Server 6.2 and WESB 6.2 as well in the future. Any ideas? recommendations? Thanks

  • SSO "Portal"

    - by Clinton Blackmore
    Pursuant to my question on alleviating the password explosion, I've contacted some of the services to whom we are paying money to access their websites to ask if we could authenticate our own users, and some of them said yes and send me specs on how to do so. (One of the sites called such a system a page a "portal"; I've never heard the term used in quite that way.) It is simple enough that I am tempted to roll my own. The largest complication is that one site wants us to store a key for every user in our database (and I think the LDAP database makes sense) after their initial login. So, non-trivial, but doable. The nature of these sorts of tasks, I expect, is that if they start out small and simple, they don't end that way. There must be some software that addresses this that is readily extended, surely. In my searching, I've come across: SimpleSAMLphp JOSSO RubyCAS-Server Shibboleth Pubcookie OpenID [Wow, gee. I'd missed some of those in my previous searches! The wikipedia page on Central Authentication Services is useful, and the section on Alternatives to OpenID makes it look like there is a lot of choice.] Can anyone recommend any of these, or suggest ones to avoid? Internally, we are authenticating using Apple's Open Directory [ == OpenLDAP + Kerberos + Password Server (which, I believe, == SAML) ]. As far as extending/tweaking/advanced configuration of a system, I am able to program in Python, C++, can do some basic PHP, and may be able to remember some Java. Looks like I need to pick up Ruby at some point. Addendum: I would also like users to be able to change their passwords over the web (and for certain users to change passwords of other users).

  • JSF and Ajax4JSF on WebSphere 6.1 --> Problem with Form Submission

    - by Shamik
    Has anyone setup JSF1.1 with Ajax4JSF on websphere 6.1 ? I followed the instructions as mentioned in the developer guide . The problem that I am facing is that once I use a4j:support on any of my h:inputText item, the form values are not getting set in the backing bean on the submission of the form. I do have <h:messages> tag present just above the form so that all the problems should be reported there but I do not see any error message once I submit the form. But I do see that the values are not getting set. I need to find the solution as early as possible otherwise I probably have to throw the ajax4jsf framework and write javascripts instead :(

  • Protecting a WebCenter app with OAM 11g - the Webcenter side

    - by Martin Deh
    Recently, there was a customer requirment to enable a WebCenter custom portal application to have multiple login-type pages and have the authentication be handle through Oracle Access Manager (OAM) As my security colleagues would tell me, this is fully supported through OAM.  Basically, all that would have to be done is to define in OAM individual resources (directories, URLS , .etc) that needed to be secured. Once that was done, OAM would handle the rest and the user would typically then be prompted by a login page, which was provided by OAM.  I am not going to discuss talking about OAM security in this blog.  In addition, my colleague Chris Johnson (ATEAM security) has already blogged his side of the story here:  http://fusionsecurity.blogspot.com/2012/06/protecting-webcenter-app-with-oam-11g.html .  What I am going to cover is what was done on the WebCenter/ADF side of things. In the test application, basically the structure of pages defined in the pages.xml are as follows:  In this screenshot, notice that "Delegated Security" has been selected, and of the absence for the anonymous-role for the "secured" page (A - B is the same)  This essentially in the WebCenter world means that each of these pages are protected, and only accessible by those define by the applications "role".  For more information on how WebCenter handles security, which by the way extends from ADF security, please refer to the documentation.  The (default) navigation model was configured.  You can see that with this set up, a user will be able to view the "links", where the links define navigation to the respective page:   Note from this dialog, you could also set some security on each link via the "visible" property.  However, the recommended best practice is to set the permissions through the page hierarchy (pages.xml).  Now based on this set up, the expected behavior is that I could only see the link for secured A page only if I was already authenticated (logged in).  But, this is not the use case of the requirement, since any user (anonymous) should be able to view (and click on the link).  So how is this accomplished?  There is now a patch that enables this.  In addition, the portal application's web.xml will need an additional context parameter: <context-param>     <param-name>oracle.webcenter.navigationframework.SECURITY_LEVEL</param-name>     <param-value>public</param-value>  </context-param>  As Chris mentions in his part of the blog, the code that is responsible for displaying the "links" is based upon the retrieval of the navigation model "node" prettyURL.  The prettyURL is a generated URL that also includes the adf.ctrl-state token, which is very important to the ADF framework runtime.  URLs that are void of this token, get new tokens from the ADF runtime.  This can lead to potential memory issues.  <af:forEach var="node" varStatus="vs"    items="#{navigationContext.defaultNavigationModel.listModel['startNode=/,includeStartNode=false']}">                 <af:spacer width="10" height="10" id="s1"/>                 <af:panelGroupLayout id="pgl2" layout="vertical"                                      inlineStyle="border:blue solid 1px">                   <af:goLink id="pt_gl1" text="#{node.title}"                              destination="#{node.goLinkPrettyUrl}"                              targetFrame="#{node.attributes['Target']}"                              inlineStyle="font-size:large;#{node.selected ? 'font-weight:bold;' : ''}"/>                   <af:spacer width="10" height="10" id="s2"/>                   <af:outputText value="#{node.goLinkPrettyUrl}" id="ot2"                                  inlineStyle="font-size:medium; font-weight:bold;"/>                 </af:panelGroupLayout>               </af:forEach>  So now that the links are visible to all, clicking on a secure link will be intercepted by OAM.  Since the OAM can also configure in the Authentication Scheme, the challenging URL (the login page(s)) can also come from anywhere.  In this case the each login page have been defined in the custom portal application.  This was another requirement as well, since this login page also needed to have ADF based content.  This would not be possible if the login page came from OAM.  The following is the example login page: <?xml version='1.0' encoding='UTF-8'?> <jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.1"           xmlns:f="http://java.sun.com/jsf/core"           xmlns:h="http://java.sun.com/jsf/html"           xmlns:af="http://xmlns.oracle.com/adf/faces/rich">   <jsp:directive.page contentType="text/html;charset=UTF-8"/>   <f:view>     <af:document title="Settings" id="d1">       <af:panelGroupLayout id="pgl1" layout="vertical"/>       <af:outputText value="LOGIN FORM FOR A" id="ot1"/>       <form id="loginform" name="loginform" method="POST"             action="XXXXXXXX:14100/oam/server/auth_cred_submit">         <table>           <tr>             <td align="right">username:</td>             <td align="left">               <input name="username" type="text"/>             </td>           </tr>                      <tr>             <td align="right">password:</td>             <td align="left">               <input name="password" type="password"/>             </td>           </tr>                      <tr>             <td colspan="2" align="center">               <input value=" login " type="submit"/>             </td>           </tr>         </table>         <input name="request_id" type="hidden" value="${param['request_id']}"                id="itsss"/>       </form>     </af:document>   </f:view> </jsp:root> As you can see the code is pretty straight forward.  The most important section is in the form tag, where the submit is a POST to the OAM server.  This example page is mostly HTML, however, it is valid to have adf tags mixed in as well.  As a side note, this solution is really to tailored for a specific requirement.  Normally, there would be only one login page (or dialog/popup), and the OAM challenge resource would be /adfAuthentication.  This maps to the adfAuthentication servlet.  Please see the documentation for more about ADF security here.

  • Introduction to WebCenter Personalization Server

    - by cindy.mcmullen(at)oracle.com
    IntroductionThe next release of Oracle WebCenter will include a new product:  the Personalization Server, developed by team members of Boulder Labs.  This team is comprised largely of the previous WebLogic Portal group, with several members having nearly 10 years' experience in personalization technologies.Customization is not PersonalizationCustomization is more of a static application behavior, such as retrieving and applying user preferences.  Personalization, on the other hand, delivers dynamic content based on run-time knowledge of the user.  It uses technology to accommodate the differences between individuals, producing the "a-ha!" experience.    WebCenter Personalization Server (WCPS) is able to integrate with and leverage many systems (property service, content management, user profile information, a recommendation service) to bring together a uniquely personalized user experience.Stay TunedUpcoming posts will discuss WCPS architecture, the Property Service, and the configuration and invocation of the OOTB "providers" such as CMIS, Activity Graph, and People Connections.

  • Web-based clients vs thick/rich clients?

    - by rudolfv
    My company is a software solutions provider to a major telecommunications company. The environment is currently IBM WebSphere-based with front-end IBM Portal servers talking to a cluster of back-end WebSphere Application Servers providing EJB services. Some of the portlets use our own home-grown MVC-pattern and some are written in JSF. Recently we did a proof-of-concept rich/thick-client application that communicates directly with the EJB's on the back-end servers. It was written in NetBeans Platform and uses the WebSphere application client library to establish communication with the EJB's. The really painful bit was getting the client to use secure JAAS/SSL communications. But, after that was resolved, we've found that the rich client has a number of advantages over the web-based portal client applications we've become accustomed to: Enormous performance advantage (CORBA vs. HTTP, cut out the Portal Server middle man) Development is simplified and faster due to use of NetBeans' visual designer and Swing's generally robust architecture The debug cycle is shortened by not having to deploy your client application to a test server No mishmash of technologies as with web-based development (Struts, JSF, JQuery, HTML, JSTL etc., etc.) After enduring the pain of web-based development (even JSF) for a while now, I've come to the following conclusion: Rich clients aren't right for every situation, but when you're developing an in-house intranet-based solution, then you'd be crazy not to consider NetBeans Platform or Eclipse RCP. Any comments/experiences with rich clients vs. web clients?

  • SharePoint - DIP problem on local copies downloaded from the portal

    - by user255234
    Our users have issues where the Document Information Panel(DIP) appears on Word, Excel, PPT documents. Here is the scenario: User downloads a copy of a template from the portal to his/her local hard drive. User edits that template and renames the file, again saving it to his/her local drive. User continues to edit and update that new document, and it continues to prompt him/her for document information as if the user was saving it on the portal. User clicks the “X” to remove this DIP bar, the next time he/she opens the local file it comes back. Is there anything I can do to make the DIP NOT SHOW on the local copies? Thanks!

  • Web 2.0 Solutions with Oracle WebCenter 11g &ndash; Book Review

    - by juan.ruiz
    Recently I obtained a copy of the book Web 2.0 Solutions with Oracle Web Center 11g from Packt Publishing, right away I noticed that one of the authors of this book is a good and long time colleague of  mine Plinio Arbizu, whom I have joined for different developer events in Latin America in the past. In this entry you will find my review of the book. Chapter 1: What's Oracle WebCenter? Provides you with basic knowledge to understand the pieces of WebCenter and the role that these pieces play in the overall Oracle Fusion Middleware strategy. Chapter 2 and 3: Will guide you through installation process and set up instructions, required to start developing Web2.0 applications. The screenshots are very helpful. Chapter 4: The chapter will guide you through a series of steps for creating a basic HelloWorld application that uses ADF/Webservices/WebCenter framework to understand the relevant pieces that are part of the architecture in large Web2.0 solutions for WebCenter. One caveat on this chapter is that the use HTML in combination with ADF Faces is not a recommended practice, because in some cases (not in this one) HTML code generated by the components can conflict with existent HTML code place on the same page... so be careful. Chapter 5: Describes the basics to understand the usage of ADF Faces Rich Client Components, with templates and ADF Business components. Chapter 6: This chapter explains how to encapsulate, deploy and consume ADF UIs as JSR 168 portlets in a declarative way Chapter 7: Explains some of the WebCenter services and the different ways that these services can be integrated within WebCenter applications. Chapter 8: Goes over how to include a series of  WebCenter services provided out-of-the-box within applications. This chapter presents a simple and clear way of how to include RSS feeds, search capabilities, tagging and discussions using practical samples that are easy to follow. Chapter 9: Presents an important component of Oracle WebCenter - the composer. Through the composer and Oracle Metadata Services the composer adds all the functionality to perform end-user personalizations, which is a very common user case when working with portals. The concept is self-explanatory when running over the practice developed in this chapter. Chapter 10: Provides an introduction to WebCenter spaces, explaining common concepts about installation, administration (role creation, group creation, etc) and through a sample, the readers can put everything in practice on their own environments. Summary: This book would provide the reader with a fast start to work with Oracle WebCenter 11g  and its different components. In my opinion the book targets the developer audience, rather than the Portal type of audience, or content generator. For the readers of this book I recommend that to better understand the concepts discussed, first you need to understand the basics on Oracle Application Development Framework. Believe me you can thank me later!

  • Cannot login to zabbix web portal

    - by hlx98007
    I've managed to install Zabbix22-server on CentOS 6.x along with php-fpm and nginx. I can view the page of 127.0.0.1 but I can only see this: After clicking the "Login" button, the page is the same: What can I do to make it work as expected, so that I can login as admin? Here are some confs: nginx_zabbix.conf: server { listen 80; add_header X-Frame-Options "SAMEORIGIN"; access_log /var/log/nginx/zabbix.log; error_log /var/log/nginx/zabbix.err.log; client_max_body_size 500M; # This folder is a soft link to /usr/share/zabbix # the permssion has been set to nginx:nginx recursively. root /var/www/zabbix; location / { index index.html index.htm index.php; } location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; include fastcgi.conf; fastcgi_param PATH_INFO $path_info; } } php-fpm is using its default values, with permission user/group set to nginx (rather than apache) Folder /var/lib/php/session has been set to nginx:nginx with permission 770. SELinux is set to disabled. I've restarted everything up to this point.

  • portal/forum for small companies to get technology help

    - by thomas
    I understand this is an open ended question and not quite sure how to add this to community wiki, if that is appropriate. I am doing a little research on where small companies would go on the internet to get answers for technology related questions. Could be around sales, servers, programming, etc. Clearly superuser.com, serverfault.com, and stackoverflow.com are excellent starting points. I am just wondering if anyone has heard of any others. Think a "facebook" that links technology providers with small companies to help answer questions and potentially provide/offer solutions. Thanks!

  • MS project publishing to TFS web portal display

    - by denis bastarache
    So, when we initially created our MPP schedule, I made use of indends / subordinates to break down the project by the various stages of the lifecycle, which is fine... no issues there... But now that I'm trying to publish this over to TFS display, it'll only pick up the actual "action items / sub-tasks" seeing as I have resource allocation specified. So for example I have an "Analysis" phase with a few items underneath, and "System Requirements" phase with the same items, so when I publish these to TFS, it won't display the "Parent" distinction between items, so both "Tasks" instances are being published in TFS under the exact same name... So, if I can't do this Automatically, I'll likely have edit each tasks with "Analysis - Item 1", "Analysis - item 2", "SRD - Item 1", "SRD - item 2"... is there a way to do this automatically, or will have to go the manual route??

    Hi all, I try to create a WebSphere queue manager in production env. Before this I manage to create the queue manager in the development env with no problem. I'm using this script to create the queue manager: crtmqm -u SYSTEM.DEAD.LETTER.QUEUE test1.qm But it give no response (no error or success message). When I try to start the queue manager (strmqm test1.qm) it give "AMQ8118: WebSphere MQ queue manager does not exist." Then I notice lots of strange thing that supposed not happen: I can run the "crtmqm -u SYSTEM.DEAD.LETTER.QUEUE test1.qm" several times without any error I can just type crtmqm and got no response I can type crtmqm -y (which is not possible since there is no -y argument) and still no response Can anyone tell me what is wrong?
