JPDK Samples

When I test the IsItWorking servlet it works fine. I tried installing the PDK-Java Framework and Samples following the newest instructions. But when I try to put the URL http://servername/servlets/samples I get the following:
NOT FOUND
The request URL /servlets/sample was not found on this server.
What could be causing this?
I do have the debuglevel=1 in the servlet.sample.initArgs.
I am using the provider.xml file found at D:\jpdk\providers\sample.
Thanks.....JS

Hi Julie,
I know it's not very exciting, but try to go over the installation steps again.
If it helps you, copy the corresponding parts of the config files here:
1) jserv.properties: wrapper.classpath=<your_jar_file>
2) zone.properties:
Servlet Alias section: servlet.sample.code=oracle.portal.provider.v1.http.HttpProvider
Aliased Servlet Init Parameters section:
servlet.sample.initArgs=provider_root=D:\jpdk\providers\sample, sessiontimeout=1800000, debuglevel=1
3) Have you modified the provider.xml file according to the physical location of the examples?
What's the physical path your example directories (helloworld, lottery, etc.) are?
Copy your provider.xml here.
Regards,
Peter

JPDK Sample Provider compile error

Hi
I have installed 'OracleAS Containers for J2EE Pre-configured PDK', version 9.0.4.
The Portlal tools are running fine, but the 'JPDK Sample Provider' fails with a compile error:
500 Internal Server Error
OracleJSP: oracle.jsp.provider.JspCompileException:
Errors compiling:C:\pdk-container2\j2ee\home\application-deployments\jpdk\jpdk\persistence\_pages\_htdocs\_testpage\_TestPage.java.
I have set the PART and JAVA_HOME environment to point to a jsdk:
java -version
java version "1.4.2_05"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_05-b04)
Java HotSpot(TM) Client VM (build 1.4.2_05-b04, mixed mode).
Any ideas???

By setting the home, are you setting the JAVA_HOME to a proper JDK installation, and not to the JRE installation?

Problems in pdk and jpdk samples?

Any known problems in the samples externalApp and iFame that comes with the latest PDK and JPDK?
I tried to install these samples by following exactly the steps in the installation html files. But, when trying to test the installation in the last step. The error messages showed up:
"Forbidden
You don't have permission to access /servlet/flightsprov on this server."
"Forbidden
You don't have permission to access
/servlet/iframe on this server."
By the way, there is no "externalApp.jar in the jpdk
Do I miss any thing? Are there walkaround?

Repository does not display JPDK samples

Hello,
I've seen several threads for people having the same issue as me, where registering a web provider appears to work, but it ends up not being displayed in the repository and the Refresh Errors page displays an HTTP_PROV_EXEC_EXCEPTION, however I am still unable to get it to work. I have tried both the JPDK and the URLServices samples. I have tried registering with hostname.domain, hostname, localhost, IP address. Does anyone have any advice for what to try next?
Thanks,
Damian

Hi Aradhana ,
1) On the menu bar, select Help->Check for updates.
2) Select the ‘Skip This Page Next Time’ checkbox and then click Next.

JPDK Samples? Nothing in my Portlets!

Server: UNIX
DB: 8.1.7
Portal: 3.08
Installed the JPDK according to the instructions and have got the sample to work as well as registered the Provider.
I can see all of the sample portlets with descriptions in the repository but when the portlet is added to a page it is blank. The only portlet that displays anything is SampleRenderer example.
I have not seen any errors in the portal but have noticed the following errors reoccuring in the jserv.log file:
1. ajp12: Servlet Error: ClassNotFoundException:
jpdk]
2. sample/Not Found: NoClassDefFoundError: oracle.jsp
.JspServlet
Does anyone have any ideas as to what could be the problem?
Thanks, Michael

Michael,
You are seeing this error message because the servlet container cannot find the classes necessary to parse and compile JSPs.
I suggest you ensure your server's classpath caontains the ojsp.jar file from the Oracle JSP Engine (required for the JPDK).
If you are using iAS (or Apache/JServ) you can verify the server's classpath by going to the JServ statuc page at http://your.server.name/jserv/

Gareth

Default implementations of JPDK V2 classes and interfaces - is the source code?

Hi
Is the source code for all the default implementations of the JPDK interfaces, renderers etc. available somewhere?

Post-installation steps
The bug fixes for bug numbers 1817550, 1830898, 1832632, 1840420, 1664594,
1810741, 1807325, and 1819442 are not installed via the patch script
because you must shut down your Web server prior to applying them. The
sections that follow describe how to apply these fixes.
JPDK.ZIP
On the Web server where the provider is running:
Unzip the contents of jpdk.zip into a directory (e.g., JPDK_30901).
Shut down your Web server.
Change your zone.properties file to include <extract
dir>/jpdk/lib/provider.jar in the wrapper.classpath.
If you are using Java Portal Development Kit (JPDK) samples from a
previous release of the JPDK, update your samples using those
included in the zip file. Refer to <extract dir>/installing.jpdk.html
for more details.
Restart your Web server.
Note: Refer to <extract dir>/release.notes.html for a list of changes made
in this release.
wwpage.jar
On the middle tier where the Portal listener is running:
Shut down your Web server.
Create a backup of your current wwpage.jar file.
Replace /$IAS_HOME/Apac he/Jserv/servlets/wwpage.jar with the new
wwpage.jar provided in this patch.
Restart your Web server.
New Parameters
The Parallel Page Engine now accepts two new parameters in the
zone.properties file:
minStall is the minimum stall value allowed for a contentfetcher
before it assumes there is a problem and times out. This value
defaults to 120 seconds. It was added to help upgrades from
308, which had a normal stall value of 40 seconds. The meaning
of stall has changed slightly, raising the need for a minimum
value.
minTimeout is the minimum timeout that may be sent by a
portlet. At times portlets send very small values, like 1
second. This almost always fails, and pages are rendered
incomplete. The minTimeout defaults to 5 seconds, but may be
set otherwise if this is not large enough. The minTimeout is
different from the requestTime. The requestTime is used when no
timeout value is sent for a portlet.
opca.jar
Back up your current opca.jar file, which is found in the
<IAS_HOME>/assistants/opca/ directory.
Copy the opca.jar file provided with this patch to the
<IAS_HOME>/assistants/opca/ directory.
To install the Portal repository, run the launch.bat (on NT) or
launch.sh (on Solaris) to invoke the Portal Configuration Assistant.
Follow the steps in the configuration assistant.
Oracle Portal Cache
Go to Oracle MetaLink and retrieve the patch for bug number 1817550.
Stop your Oracle HTTP Server.
Apply the patch you downloaded from Oracle MetaLink as per the
instructions in the README.txt file.
Login to your system as root and delete all cache files and
subdirectories under the directory
<IAS_HOME>/Apache/modplsql/cache/plsql. Make sure the directory
<IAS_HOME>/Apache/modplsql/cache/plsql is empty.
Start your Oracle HTTP Server.
Bugs fixed by this patch
This patch fixes the following known bugs:

This bug pertains to a synchronization issue in the 3.0.9
fetching of portlet content. The Document could not be
contacted error is randomly raised. However, it may be
that other problems are causing this error. This bug only
refers to the synchronization issue in which the Parallel
Page Engine causes the problem.
1810741 PROVIDER USER DOES NOT DETECT PUBLIC USER CORRECTLY.
Previously, the JPDK did not correctly detect if the
current user was logged in or accessing the portal using
a public session. This bug also affected providers
registered with a login frequency of PUBLIC. Failure to
detect the logged in state of the user correctly caused
ProviderUser.isPublicUser() to return an incorrect value
when a provider written using JPDK release 3.0.9 was used
with earlier releases of Oracle9iAS Portal.
The most common symptom of thi s error is the Customize
link being shown to public users when the provider
definition specified that it should be hidden. A new
username parameter has been added so the JPDK can
correctly detect the logged in state of users while
maintaining backwards compatibility with older versions
of Oracle9iAS Portal.
1811275 GROUP NAME IS REPEATED IN LIST OF GROUPS IN SPANISH,

the Oracle9iAS 1.0.2.2 installation.
1819442 PROVIDE MINTIMEOUT FOR PPE TO OVERRIDE SMALLEST
TIMEOUT(S).
Previously, there were no minimum values for timeouts.
The fix for this bug adds some minimum values for
timeouts and changes the defaults such that the Parallel
Page Engine works better without any configuration by the
user. These changes help to prevent getting the Portlet
could not be contacted error message.

Richard,
I have just applied patch to upgrade from Portal 3.0.9 to 3.0.9.8.1 (Patch applied to loginserver and portal schema) and the External Applications that were previously set up have gone from the portlet.
Does this relate to your note at the bottom:
"Minor issues with Bulk action. 1840420 CUSTOM WRITTEN EXTERNAL AUTH MODULE NEED TO BE UPDATED AFTER 3.0.9 UPGRADE SSOXOID.PKB DOESN'T LOAD.
External authentication modules that were written before 3.0.9 need to be updated after upgrading to 3.0.9. ssoauthx.pks is updated in 3.0.9 and contains additional routines that need to be implemented." ??
If I go to the "Login Server Administration" portlet and select the link "Administer External Applications" I get a list of 5 External Applications that have previously been set up.
If I go back to the Home Page and select "customize" on the "External Applications" portlet I get the message "Your Login Server administrator has not registered any external applications".
Does that mean I should just run 'ssoauthx.pks' & 'ssoxoid.pkb' or do I need to do something else ??
Thanks

Calling portal v2 pages with parameters in a jsp

     Hello everybody,
     I'm currently trying to create, in a jsp, a link to a portal-v2 page with parameters.
Practically :
[JSP / Portlet 1]
     - a 1st jsp generates some links, all to the same page but each sets a different value to a parameter (for example a productId in a list).
[JSP / Portlet 2]
     - a 2nd jsp gets this parameter and use it (for example it displays the details of the chosen product).
So the 1st portlet would be jsp (coded by a portlet designer) and clicking a link would lead to another page (chosen by a page designer) which would hold the 2nd portlet (= 2nd jsp, coded by the same portlet designer).
     Writing the second jsp is easy : getting parameters is described in many examples and pdk articles.
     But I can't find the java methods to use to generate the link. More precisely I don't know how to call the portal page (which would then be a jsp1's parameter). Adding the parameter is well described in the jpdk API-Doc.
     I've tried to use portal events but they seem to work only in an html form. So I supposed it was a wrong way.
As I've lost myself so many times in the API-Doc and I didn't find any jpdk sample about that, I would be really thankfull if someone has an idea (may I hope for a sample code ? :-)
Thanks.
Jean-Roch

I'm having a similar problem!
I have a JSP page which I have published as a portlet to Portal. The JSP portlet is placed on Portal a page. I need to call this Portal page with some parameters in the URL, which should get passed to the JSP portlet.
In the JSP portlet I used this syntax in release 1 to retrieve the URL parameters:
String p_itemID = request.getParameter("item_id");
That worked great in release 1, but not in release 2.... I think the problem is that you need to define which parameters a portlet has, then map those portlet parameters to page parameters in the page properties. In dynamic page - portlets you define bind variables to accomplish this. But how do you do in JSP portlets? When you try to map Page Parameters to the JSP portlet you'll find that Portal doesn't think that the JSP portlet has any parameters. Hence the page parameters does not get passed to the portlet.
(More info: JDBC----getImportedKeys() )
I've looked at the Multipage example and the forminput example. But I don't see how pass a parameter in the URL to the very first JSP portlet from looking at those examples. I do see how you can pass parameters to the next JSP portlet, but that's not my problem. Maybe I'm missing something obvious...
Any ideas?

10.1.2.0.2 Resource proxying constructResourceURL without change

10.1.2.0.2 supports for the first time to tunnel resources like images from the provider directly thru the Portal.
Unfortunately we don't get it to work as expected. You can easyly reproduce using the JPDK samples. The lotto sample has allready implemented the feature:
IMG SRC="<%= UrlUtils.constructResourceURL(portletRequest, HttpPortletRendererUtil.absoluteLink(request, "images/ball" + picks[i] + ".gif")) %>" WIDTH="68" HEIGHT="76" ALIGN="BOTTOM" BORDER="0"
but when accessing the portal page the image links are still the old ones (http://<webapp_url>/jpdk/htdocs/lottery/images/ball1.gif) but should be something like http://<portal_url>/portal/...provider...resource=http://<webapp_url>/jpdk/htdocs/lottery/images/ball1.gif
Do you have a hint for us?
thanks
Heiko

In order for the JPDK to generate links that use resource proxying, both the PPE (Portal) and JPDK must be configured with a shared key.
For the PPE, an init-param called resourceUrlKey must be defined.
For the JPDK, a JNDI environment variable with the same name (resourceUrlKey) must be defined.
The key must have the same value in both places.
Please see section 4.11 of the 10.1.4 Portal Configuration Guide for more information.
The JPDK will fall back to the old behaviour if either key has not been set -- which is what I think you are seeing in your case.
I hope that helps.
Andy.

PUBLISHING OC4J JSP as web portlet

I have developed a JSP page in OC4j and want to publish this page on portal 3.0.9 as web portlet. I have created web provider and registered this page as portlet. When I view the portlet it comes as a Blank Page.
Can anyone tell me how to publish a JSP page developed in OC4J as a web portlet? Can I publish JSP web pages developed in OC4J as web portlet without modifying any JSP code?
I have installed all JPDK samples and they are working fine.
Regards

Here is what we are forced to do, because V2 has had a great delay in the time scheduling.
Hope it helps. Anyone better ideas?
Michael.

Have you resolved this? I am interested in finding out what happened with this problem 'cause I am getting the same error when I did the same with JPDK sample web application. I was able to install it on NT with no problem. But when I tried to do the same in Solaris the problem came up.

Convert existing servlet into portlet

Hi
We have a set of Java servlets running on apache and jserv and not using Portal. My task is to be able to convert these into Portal.All of the existing servlets are extends/use our existing set of classes. They display a list of rows in a table as HTML with a URL pointing back to the same servlet or different servlet based on logic, with set of parameter. With my current setup (all on a Win2000 system), I have installed the JPDK samples and it is working fine, but have now got stuck in applying the concepts to my own existing servlets. So can you help me how can i convert an existing Java servlet into Portal?
First i tried the "how to build your own java portal exercise" and it runs fine. But when i tried to run simple servlet to convert into portlet, i got the following error. I am really confuse about Renderer. Is it nessessary to make Renderer or use Default Renderer? I will really thankful to you if you give me some idea.
I changed the following in to conf/jserv properties.
1. set the " <showPage class="AgeServlet"/> " in provider.xml
2. in zone property
servlet.AgeServlet.code=oracle.portal.provider.v1.http.HttpProvider
servlet.AgeServlet.initArgs=provider_root=C:\MyProvider,sessiontimeout=1800000,debuglevel=1
3. In jserv property
wrapper.classpath=C:\MyProvider\MyClasses
Where i put my AgeServlet.class
4.Stop and Start the Oracle HTTP Server.
When i try to run url(http://host.domain:port/servlet/AgeServlet) it gives me following error.
Error!

Supressing Portlet Header programatically

All,
I need to supress the Portlet header. I would like to do this without using the customize tab. The API says that the portlet_runtime_record has the has_title_region attribute. How can I set this value to false, so that the header is suppressed automatically.
Rgds
Sanjay

That's right because you have multiple provider instances deployed. Each provider has its provider.xml for its configuration. To locate the appropriate provider.xml you need to identify the provider instance. For instance if you use the JPDK sample provider in your portal installation (http://host:port/jpdk/providers sample) then the location of the provider.xml will be $ORACLE_HOME/j2ee/OC4J_Portal/applications/jpdk/jpdk/WEB-INF/providers/sample.
Note that the location of the provider.xml within the deployed provider application is defined in the sample.properties located in $ORACLE_HOME/j2ee/OC4J_Portal/applications/jpdk/jpdk/WEB-INF/deployment.
You now have access to the provider settings and you can set the renderer for each portlet of the provider individually. By default the standard portlet renderer class is used. You need to write you own renderer class. For more information about portlet development you need to look at the documentation. Starting point is http://www.oracle.com/technology/products/ias/portal/index.html

JPDK June - Portlet customization sample question

Hi,
I was wondering whether someone could help me out with the customization sample provided in the JPDK distribution of June.
Since BaseCustomization usage is deprecated I'm trying to use subclass the 'NameValuePersonalizationObject' class. However until now I've not been able to change title nor (default) message of the portlet. What am I doing wrong?
Thx.

Jan,
I need a few more details here! Do you mean that you have created your own portlet and are having trouble implementing customization?
Please repost with a few more details, include your usage of NameValuePersonalizationObject and the context in which you are using it.
Regards,
Gareth

JPDK - Unable to see Sample provider in repository - getting Error

I have been trying to intall the sample provider as outlined in
the document "Installing the PDK-Java Framework and Samples".
Everything works fine except that I am unable to see the
provider in the repository...even after I refresh the repository
or restart the server. I see the following error when I click
the Refresh Error link in the Portlet Repository;
wwpro_api_provider.get_portlet_list 09-OCT-2001
PROVIDER[1097547]: SampleWebProvider
LANGUAGE: us ERROR: HTTP_PROV_EXEC_EXCEPTION
I am able to see the test page fine and don't have a problem
registering the provider, it just doesn't show up in the
repository and I cannot add the provider to a page.
Has anyone encountered this problem?
Were you able to solve it?
Any ideas on how I might fix this problem?

Hi , me too I have the same problem.
I cannot see the sample portlets in the portlet repository , after I have succesfully registered the provider , in the "administer" tab of Portal.
If I click the refresh error , I see this error : wwpro_api_provider.get_portlet_list 12-SEP-02 PROVIDER[208]: JSP_esempio LANGUAGE: us ERROR: HTTP_PROV_EXEC_EXCEPTION
My jserv.log says :
[12/09/2002 13:59:39:007 GMT+02:00] sample/DefaultProvider.getPortlets() - ProviderId = -1

[12/09/2002 13:59:39:007 GMT+02:00] sample/DefaultProvider.getPortlets() - returning 14 of 14 portlets
It sounds good :-)
jserv_mod.log doesnt give errors.
My environment is:
9iAS : 1.0.2.2.2
Portal : 3.0.9
JPDK : 3.0.9.0.7.
Any suggestions ?????
Please help me !
Max
