Integrating Struts portlet

Hi guy,
just to share my first experience with a very simple struts application integration (luckily)
I've transformed my webapp in a module as stated in http://edocs.bea.com/wlp/docs100/portals/integrate.html#wp1005659
I've got to say that this was a legacy application developed by someone else in the company.
I've found that if you had in your struts-config path action like /somename/actionname the engine get confused and give you an error
There is no Struts module configuration registered for /modulename/somename/actionname.do (module path /modulename/actionnameSo it looks like he mix the path with the module name.
I've changed action path (lukyly my webapp was really tiny)
Then I've also tried to manually add my module xml (struts-config) to web.xml, I've copied it under classes and I've added to web.xml
       <init-param>
            <param-name>config/modulename</param-name>
            <param-value>/config-modulename.xml</param-value>
        </init-param>Well it gimme an AssertError
java.lang.AssertionError: modulename

...I'd a look at the beehive source and there's this assert in the code that expect a name startWith '/' (so for some reason the engine take the name but it miss the '/')
Well that's it, it takes a while to me to find out this problems so I hope I can save someone time.
And bytheway if some of you solved this issues can be interesting to know (maybe I missed something in my configuration?)

Struts portlet integration

Hi,
sorry I'm new to weblogic but had used different app servers before. I have to do such a project until next week where you need to put the coffee machine directly beside your computer. ;-o
I already had implement my entity beans and session beans in a xdoclet / maven environment.
Now I need to do the view tier and integrate it in a existing porlat as portlet.
Here my questions:
Should I do my UI via Struts since I'm familar with struts and it would be staight forward. Should I as last step import the final struts & ejb application as portlet to workshop? What and how much work is to do to make a strus application to a portlet?
Or may alternativly should i realize my UI directly in workshop and do this jpf stuff?
As you can see I'm fishing for experimence reports about integration struts / ejb in existing portal workshop projects.
Thanks a lot for any hints.
Stefan

glad to hear im not the only one struggling with integrating ADF with Portal.
ADF consists of 3 layers,
1) Business Layer (model/bc4j)
2) Controler Layer (struts)
3) View Layer (uix/jsp/jsf)
A portlet ussualy takes care of the Controler Layer and the View Layer, it should be possible to use BC4J within your portlets, but not using layers 2 and 3.
But I guess this is not what we want, we want to create an ADF application within
JDeveloper and deploy it either standalone or as a portlet.
I wonder if this is possible with JSF, it doesnt contain struts anymore, so perhaps the
layered complexity is less?
An option is always to use the webclipping portlet, but this is not ideal.
Im curious how Oracle is going to address this, we now have 2 platforms we can develop
applications for, Portal and Standalone (ADF). Its kinda a waste that portlet development
is like developing a servlet, not using a luxery framework like ADF.

Creating Struts Portlet

Hi,
I am new to Weblogic Portal, I have integrated the struts application and also created the portlet for that. When I attach the struts portlet to Portal file and run my portal application. It shows me the blank portlet.
I am not getting any issue/ error/ problem.
I have included the
<controller processorClass="com.bea.struts.adapter.action.AdapterRequestProcessor"/> in my struts-auto-config-hello.xml file also I have included the
<init-param>
<param-name>config/hello</param-name>
<param-value>/WEB-INF/struts-auto-config-hello.xml</param-value>
</init-param>
in my web.xml file.
Still I am gettin the blank Struts porlet. Please suggest.
Thanks in Advance.

Error after creating a struts portlet in weblogic 8.1 SP 5

Hi,
I am using weblogic 8.1 SP 5, to develop an struts-portlet.
I tested my struts application and it is working fine.
I have one action i.e firstAction and 2 jsp's in my struts application.
The action just forwards to the one jsp through struts-config.
However, when i try to start the server after creating the struts-portlet i get the following error:
The source of this error is com.bea.netuix.nf.UIControlException: For portlet [portlet_1_1], could not retrieve a result for the given action [firstAction] in the given PageFlow: [null]. at com.bea.netuix.servlets.controls.content.NetuiContent.preRender(NetuiContent.java:365) at com.bea.netuix.nf.ControlLifecycle$7.visit(ControlLifecycle.java:443) at com.bea.netuix.nf.ControlTreeWalker.walkRecursivePreRender(ControlTreeWalker.java:718) at com.bea.netuix.nf.ControlTreeWalker.walkRecursivePreRender(ControlTreeWalker.java:730) at com.bea.netuix.nf.ControlTreeWalker.walkRecursivePreRender(ControlTreeWalker.java:730) at com.bea.netuix.nf.ControlTreeWalker.walkRecursivePreRender(ControlTreeWalker.java:730) at com.bea.netuix.nf.ControlTreeWalker.walkRecursivePreRender(ControlTreeWalker.java:730) at com.bea.netuix.nf.ControlTreeWalker.walkRecursivePreRender(ControlTreeWalker.java:730) at com.bea.netuix.nf.ControlTreeWalker.walkRecursivePreRender(ControlTreeWalker.java:730) at com.bea.netuix.nf.ControlTreeWalker.walkRecursivePreRender(ControlTreeWalker.java:730) at com.bea.netuix.nf.ControlTreeWalker.walkRecursivePreRender(ControlTreeWalker.java:730) at com.bea.netuix.nf.ControlTreeWalker.walkRecursivePreRender

Hi,
Even I am facing the same issue could any body help me out to solve this issue.

Trouble with console-extension using struts portlet

hello everyone,
I'm developing a console-extension for wls9.2 but couldn't get is to work despite all the documentation available. The console-ext is a struts portlet which gathers data from custom mbeans via jmx and renders the result with a jsp. What already works is fetching the data from the MBeans in the struts action. What does not work is the display of the results in the admin console. So I removed all the stuff from the jsp to just display "Hello World" which should be displayed on the desktop in the admin console, but even this didn't work (it's just a blank spot). Having a look at the log file I get the following:
e.netui.pageflow.internal.AdapterManager ERROR ServletContainerAdapter manager not initialized correctly.
e.netui.pageflow.internal.AdapterManager INFO No ServletContainerAdapter specified or discovered; using class org.apache.beehive.netui.pageflow.DefaultServletContainerAdapter

(...other debug output from my struts action...)

.netui.pageflow.PageFlowRequestProcessor INFO Attempting to instantiate SharedFlowControllers for request /console/ChangeManagerAction.do
ive.netui.pageflow.FlowControllerFactory INFO No Global.app was found in /console
Despite the errors it seems to find my struts config (struts-auto-config-loggingController.xm) and execute the action, but then it seems to have trouble findingd/displaying the jsp (helloWorld.jsp). I tried to set various controller-elements in the struts config, like this ([url http://edocs.bea.com/wlp/docs92/portals/integrate.html#wp1005659]source):
<controller inputForward="true" processorClass="com.bea.struts.adapter.action.AdapterRequestProcessor" />
but this didn't work either (and results in other errors). The log from above was created with a config without any controller element (since this is never mentioned in the eDocs for console extensions).
Despite spending several hours trying to figure out what goes wrong here I wasn't able to get one step closer to a solution. Does anyone have a clue what I did wrong (please ask if you need further information)? Thanks a lot!
Btw. Sorry if this is the wrong forum, I could't find another one which matches better. Feel free to move the topic to a more appropriate place. thx.
====================================
Struts config:
<struts-config>
     <form-beans>
          <form-bean name="loggingForm" type="...web.forms.LoggingControllerForm" />
     </form-beans>
     <action-mappings>
          <action path="/LoggingControllerAction"
               type="...web.actions.LoggingControllerAction"
               name="loggingForm"
               scope="request"
               validate="false"
               input="/ext_jsp/helloWorld.jsp">
               <forward name="success" contextRelative="true"
                    path="/ext_jsp/helloWorld.jsp" />
          </action>
     </action-mappings>
</struts-config>

The problem could be solved by adding the "handle" property (of type com.bea.console.handles.Handle) to the form bean.
This is stated on page 7-4 in the "Extending the admin console" guide or [url http://e-docs.bea.com/wls/docs92/console_ext/simpleext.html#wp1083856]here
In addition the following controller element must be used in the struts config: <controller inputForward="true" processorClass="com.bea.struts.adapter.action.AdapterRequestProcessor" />
This is not mentioned anywhere and should definitely be added to the guide.
Hope this helps someone encountering the same problem.

Struts Portlet With Input Parameters

Hi Everyone,
Am I able to write a struts portlet that has input parameters? Right now, I have a struts portlet with a provider.xml that looks like this:
<?xml version = '1.0' encoding = 'UTF-8'?>
<?providerDefinition version="3.1"?>
<provider class="oracle.portal.provider.v2.DefaultProviderDefinition">
<session>true</session>
<passAllUrlParams>true</passAllUrlParams>
<portlet class="oracle.portal.provider.v2.DefaultPortletDefinition">
<id>1</id>
<name>ManageQuotes</name>
<title>Manage Quotes Portlet</title>
<description>Manage Quotes Portlet</description>
<timeout>40</timeout>
<showEditToPublic>false</showEditToPublic>
<hasAbout>false</hasAbout>
<showEdit>false</showEdit>
<hasHelp>false</hasHelp>
<showEditDefault>false</showEditDefault>
<showDetails>false</showDetails>
<inputParameter class="oracle.portal.provider.v2.DefaultParameterDefinition">
<name>encryptedDealerNumber</name>
<displayName>encryptedDealerNumber</displayName>
</inputParameter>
<renderer class="oracle.portal.provider.v2.render.RenderManager">
<renderContainer>true</renderContainer>
<renderCustomize>true</renderCustomize>
<autoRedirect>true</autoRedirect>
<contentType>text/html</contentType>
<showPage class="oracle.portal.provider.v2.render.http.StrutsRenderer">
<defaultAction>/viewquotes.do</defaultAction>
</showPage>
</renderer>
</portlet>
</provider>
The <session>true</session> and <passAllUrlParams>true</passAllUrlParams> need to be there to have a struts portlet. The problem is when I put my portlet on a page and then check out 'Page Properties', 'Portlet Parameters', there are no parameters that show up for my portlet. Can anyone help me?
Thanks
Cory

I just went through this two days ago. I ended up logging a TAR/SR with Oracle and it turns out Struts portlets do not support input parameters. Instead you have to set the passAllUrlParams tag to true and then just use portletRequest.getParameter("parameterName") to retrieve page parameters. You have to be careful here because in this older style of doing parameters you have to manage all the uniqueness in naming parameters in case you have more than one portlet on the same page. However, it seems that if all you want to do is read the portal page parameters that unique naming doesn't come into play.
In my case I have an OmniPortlet setting some Page Parameters via an Event. Then in my struts portlet I just do:
String foo = "";
String bar = "";
PortletRenderRequest portletRequest = (PortletRenderRequest)
request.getAttribute(HttpCommonConstants.PORTLET_RENDER_REQUEST);
if ( portletRequest != null ) {
foo = portletRequest.getParameter("Foo"));
bar = portletRequest.getParameter("Bar"));
That seems to work just fine for me, but in my case I will only ever use my portlet once per page so this fine. If you wanted the same portlet to have different page parameters fed to it for different instances on the same page this style won't work since all the portlets would just read the same page parameters since those page parameters names are coded in the implementation code.
Hope that helps,
David

Strut-Portlets errors in Weblogic 8.1 SP5

I am getting the below mentioned error when running a portal containing Struts-Portlet in Webloigc 8.1Sp5.
I have tried everything but not able to resolve it, does anyone know how to resolve and how to successfully run a Struts-Portlet application?
Thanks in advance.

What happens in a Struts Portlet is that Portal calls into NetUI to get the action to forward to. The problem appears to be that the struts-config is not getting picked up or registered with NetUI.
One thing to try is to do inter-op between Struts and NetUI/pageflows first to make sure the struts-config is being picked up and then layer on the Portal layer.

Struts Support: "Cannot parse the struts configuration file" when using the Struts Portlet Wizard

I'm currently trying to deploy the struts-example webapp from Struts 1.1 RC1 into
Weblogic Portal 8.1 using the Struts Portlet wizard made available by the "JSR
168 and Struts Support" patch.
I select the struts module successfully "struts-example" and am prompted for the
location of name mangled configuration file (i.e "struts-config.xml" for struts-example
becomes "jpf-struts-config-struts-example.xml").
As soon as I hit next, I am prompted with a dialog informing that me that [Workbench]
"Cannot parse the struts configuration file."
Given that this is a file supplied with the struts distro and that I can deploy
the struts-example to Vanilla WLS 8.1 without problems I suspect this is a problem
with my attempt to use the Struts Portlet.
Can anyone please help?
Thanks,

Struts portlet data binding

Struts project using syntax like
<c:out value="${bindings.RaeCustomersView1.labels['Role']}"/> works fine unless deployed as a struts portlet.
As a portlet all the bindings are null.
This is a major pain !!!
Has anyone any ideas.

ok, just to be more specific.
If it is a bind control that is modified from the front panel, it works fine even from remote panel. However, if you modify it through a local variable, it wont have any effect on the bound shared variable.
For this reason, all the changes made to bind indicators wont take effect on the corresponding shared variable either.
A 2nd work around is to use the property node -> value and that will affect the shared variable correctly. However, I read somewhere that we should reduce the number of property nodes to a minimum when planning to use the remote panel so updating the shared variable directly still seems best.

CSS for WSRP Struts Portlets

I have a Struts 1.3 Portlet running in WLP 10.3.2. The css inside JSP displays right in a web-app. But when I expose over WSRP, the css is not getting applied.
Here is the simple jsp I have:
test.jsp
<style type="text/css">
.test{
border: 2px solid red;
background-color : blue;
</style>
<span class="test">CSS Testing</span>
Qn. 2)
Do I need to have html,head and body tags for Portlets that I want to expose over WSRP?
Qn3) Do I need to go for render dependencies here..

Just in case you haven't seen this, I will add in this doc link as well on how to configure render dependencies in the portlet.
http://download.oracle.com/docs/cd/E15919_01/wlp.1032/e14244/configure.htm#i1073504
I haven't done this with a struts portlet, but in my example, the .portlet file on the producer would have a
"lafDependciesUri=/test.dependencies" with the css code you posted in it.
So the "test.portlet" file on the producer would have something like this:
<netuix:portlet definitonLabel="myportlet" title="simple test" lafDependenciesUri="/yourpath/test.dependencies">
</netuix:portlet>
then on the consumer side, the proxy portlet ".portlet" file would have something like:
<netuix:proxyPortlet>
invokeRenderDependencies="true"
</netuix:proxyPortlet>
this should allow the proxy portlet to obtain render dependencies from the producer during prerender lifecycle.

Logging doesn't work from my Struts portlet

I've got a Struts portlet that uses (or tried to use) Log4J logging. I don't get any logging - not even .log file creation. When the OC4J instance starts up it gives a warning about not having the Log4J system initialized properly. I have a log4j.properties in my WEB-INF/classes directory so I don't understand why it gives this warning, though.
Is Struts overriding Log4J logging with its commons-logging.jar?
I also don't get an application.log file which the portlet should create in the applications-deployment/ directory.
Has anyone run into this with a Struts portlet?

I should have mentioned that I'm deploying my Struts Portlet in a local OC4J (with PDK support) and using it as a provider to a remote Oracle Portal. For some reason OC4J doesn't recognize the log4j.properties that is in my WEB-INF/classes directory.
I've also got a TAR opened with Oracle Tech. support and when they deployed my .ear file to a Portal they get an application.log file which I do not get. There must be something on my local OC4J that prevents any logging (neither the application.log or the log4j .log file gets created on my local OC4J).
Here are the messages that I get when I start OC4J:

How can I display UTF-8 content in a struts portlet

How can I display UTF-8 (with English and Traditional Chinese mixed characters) content in a struts portlet?
Version used
Oracle Portal 10g Release 1 (9.0.4) on Linux
Portal language support: English only
Many thanks !!!

You can utilize multi-lingual support in your Struts portlets, as described in the Portal Developer's Guide.

Struts portlet and request.getQueryString()

Hi all,
I've run into what seems like a bug in using struts portlets.
In my JSP page, I'm attempting to retrieve the query string (parameters) from the request URL, but apparently under the Portal framework, only the first parameter/value in the query string can be retrieved.
Eg. URL:
http://www.myportal.com/portal/page?_pageid=11,86282&_dad=portal&_schema=PORTAL&_piref33_92271_33_86282_86282.strutsAction=%2myAction.do?param1=abc&param2=cde&param3=fgh
When invoking a request.getQueryString() either in my JSP or in the action servlet, only the first part is returned, which is param1=abc. The rest is dropped.
I should mention that the actual use of these parameters are okay (such as request.getParameter("param2") will return "cde"). Just pulling them out with the getQueryString() method seems not too work.
The only way to workaround it for me is to use the request.getParameterNames() and run through the enumeration and construct the query string manually. Of course this is ugly running under the Portal framework because I have to filter out all the Portal parameters that begin with the underscore character(eg. page, schema, etc).
Has anyone else had this problem and worked around it?
Thanks in advance

Hi,
This may help. Use the pdk-struts-html:link tag instead.
Something like
<jsp:useBean id="prevDetail" class="java.util.HashMap"/>
<c:set target="${prevDetail}" property="event_PreviousSet" value="PreviousSet"/>
<c:set target="${prevDetail}" property="sortref" value="${param.sortref}"/>
<c:set target="${prevDetail}" property="sortacc" value="${param.sortacc}"/>
<c:set target="${prevDetail}" property="filteron" value="${param.filteron}"/>
<pdk-struts-html:link action="portal/something.do" name="prevDetail">
Good luck, Hernando

Struts Portlet does not show images when it is accessed outside the domain

Hi all,
I am using Oracle 10.1.2. I have created a Struts portlet. When I view the struts portlet from my office domain (University domain) it works well and shows the images properly. However, if I try to access the same page containing the struts portlet from some other domain (my home), I cannot see the images and CSS associated with the page. This might be a firewall issue. Is there any way out?
Best regards,
Omer

I fixed the problem. (YAY!)
It was the way I embedded the files -- the Dreamweaver default does not work properly so I used the embed from this generator: http://www.bobbyvandersluis.com/swfobject/generator/index.html#alternativeContentHelp which now lets my navbar and swfobjects load properly. I also made sure that my slideshow (loader.swf) was set with wmode = opaque while the navbar is set to wmode = transparent. The div for the nav bar has z-index set to 5 while the div for the slideshow has z-index set to 1. Both have absolute positioning. I hope this helps anyone in the future that has trouble with overlaying flash (.swf) files.
Thanks for your reply and trying to help me solve this issue!
