PortletDevelopment: How to access page properties?

[nis...@gmail.com]

Hi guys,

I am trying to access the Navigation three of portal. I have used following code to generate sample tree. While compiling this code jsp it gives excetion on NavigationSelectionModelHome class not found. and package not on classpath.

In fact I want to use Model API of portal server. But I am not sure how to load this api in classpath.

try{
Context ctx = new InitialContext();
NavigationSelectionModelHome home = (NavigationSelectionModelHome)
ctx.lookup("portal:service/model/NavigationSelectionModel");
if (home != null) {
NavigationSelectionModelProvider provider =
home.getNavigationSelectionModelProvider();
NavigationSelectionModel model =
provider.getNavigationSelectionModel(request, response);

Hope you can help me in this context.

Thanks in advance.

JSP is attached with full code

Jaydeep.

There are hundred of JARs. And It should be some standard way to include the class to classpath.

B'cos exception is comming in theme resourece.

Can u tell me which jar file contains Model API

[radhakris...@gmail.com]

Search for com.ibm.portal.model.NavigationSelectionModelHome in the JAR's in /PortalServer/shared/app and include that JAR.

Thanks,
Mohan

Is this compilation at run time or in RAD? If in RAD just to your web project add the portal server runtime, and the portal server JDK, if at run time, where are you putting the jsp? as a web app, how did you install it?
IBM Certified System Administrator -- WebSphere Portal V6.0, V5.1, V5.0

It is compilation at run time. To be more clear it is not Web project or not at all in my web project. It is part of Default.jsp in theme in Portal server.

I am adding jsp (attahced in first post) in Default.jsp. And after I start my portal server. It Just shows following errors on console followed by stack trace.

I am using WebSphere Portal Server 5.1

[Jim Barnes]

5.1.0.? which point release?

[Jim Barnes]

can you let me know what version of portal you are on? these classes should already be in the classpath for the portal

Jim

[Jim Barnes]

Just as a followup I ran your JSP on my 5.1.0.4 system and it worked fine.

[Jim Barnes]

There in lies part of the problem, the model SPI was introduced in 5.1.0.1, you are running on 5.1.0.0, you need to upgrade your rad test environment. you can use the rad product updater to do this, and go to 5.1.0.4

[nis...@gmail.com]

Thanks Jim,

I don't have right to update version.

But I have confired with one persone here the version.He says we are having 5.1.0.3

Do I have any other way of using Model API.

I am thanks ful to you for you quick replay and putting your time to run jsp.

[Jim Barnes]

Not in the test environment, there is alot besides just the public api that would need to be copied over, as your test environment is 5.1.0.0, you really need to get it to at least 5.1.0.1 if you want to test the model api locally. if your production version is 5.1.0.3 the jsp runs on that as well and I have tested it there as well.

[mgg...@gmail.com]

Try this jar,
wp.model.api.jar

[Jim Barnes]

I would not recommend copying that jar over from your 5.1.0.3 environment to your local test environment which is 5.1.0.0 it could cause all kinds of issues. The bigger issue here is that the model SPI was not available until 5.1.0.1 of portal or later. So you need to get your 5.1.0.0 test environment upgraded if you want to do local testing

[nis...@gmail.com]

Thank to all of you guys there for all your replay.

But if we come back to original question. I need to get the Navigaition tree.

All the labels and pages with name and url.

on WebSphere Portal server 5.1.0.0. If there is any way please suggest me.

Jaydeep

[Jim Barnes]

you can just go through the navigation loop, and only for pages that are in the navigation path print those out.

you can try something like this, not sure if it works in 5.1, it did work for 5.0
com.ibm.wps.model.ModelUtil modelUtil = com.ibm.wps.model.ModelUtil.from( request );
com.ibm.wps.model.NavigationModelUtil navModelUtil = com.ibm.wps.model.NavigationModelUtil.from (request);
if (modelUtil != null) {
com.ibm.portal.navigation.NavigationSelectionModel selectionModel = modelUtil.getNavigationSelectionModel();
java.util.Iterator selectionNodeIterator = selectionModel.iterator();
while (selectionNodeIterator.hasNext()) {
com.ibm.portal.navigation.NavigationNode currentNode = (com.ibm.portal.navigation.NavigationNode)selectionNodeIterator.next();
href="<%=navModelUtil.createSelectionChangeURL(currentNode)%>"><%=modelUtil.getTitle(currentNode)%></a>

but my recomendation would be to get your admin to upgrade you to at least 5101 since you are on 5103 in production and then you can use the SPI. There is no way to get the SPI in 5100

[Jim Barnes]

Scroll down for the spi docs at the bottom it includes the javadoc for that

Thanks Jim.

I have tried with Model Api. Its working fine in JSP page. I have tried in one of the portlet.

But when I tried with making Java file of same code and call that class in same JSP it give these exception. Jsp and java file is in same portlet project. Jsp works Java files gives these exeptions.

[Jim Barnes]

are you still doing this on the same rad environment that only had 5.1.0.0? if so you need to upgrade so that it picks up the right jars to compile against.

[nis...@gmail.com]

No I am using 5.1.0.3. But that is in Test Environment. No on my local. So I need to deploy portlet to test.

But JSP is woring, why Java file is not working with same code.

It is very strange....

[Jim Barnes]

are you trying to pass in the portlet request to the service?

If you want you can send me your portlet and I can take a look at it real fast
Jim

[nis...@gmail.com]

Hi Jim,

Find the code in attached java file.

And I am calling it code in jsp like

<%
dk.bankdata.kort.testdriver.commands.NavigationTreeUtil n = new dk.bankdata.kort.testdriver.commands.NavigationTreeUtil();
out.write(n.getFullNavigationTree(request, response, 2));
%>

And it give exception that i have shared in previos post.

But if i use same code full in jsp it works.

[Jim Barnes]

I would need to see how you have packed your portlet.
everything looks like it should work

[Jim Barnes]

I put this into a war, and called it just like you did

and it worked fine for me
