Content Server Portlets Not Displaying

Help!
We're running Portal v5.04, Java under Windows, Content Server v6.0, Tomcat v4.1.31. Multi-machine installation...
After logging into the portal as Administrator (or some user with admin privileges), we get an error where the Content Server Administration portlet is placed saying "Content Administration cannot be displayed due to an unknown error.". Get the same thing with any other Content Portlet...
This installation was fine beginning of last week, but started showing this problem late in the week. All of the diags I know of for testing Content, Collab, and Studio (all installed on the same server) show all greens. Tried looking at logs - nothing. Tried PTSpy during login (portlet is on "My Home" page - should display automatically) - nothing remarkable.
We have multiple admins, and it's possible that something was changed (unbeknownst to me). Frustrated and not sure even where to start looking for a solution to this. Any Ideas?
Thanks!

The fact that bouncing EBS fixes the issue temporarily indicates that the problem is most likely on the EBS end, but we haven't encountered that specific issue. What OS are you using to host EBS? Are you purging the J2EE cache when you bounce the services?
Feel free to reach out to Anne or myself if you'd like to dive into this. We could test with an alternate content server to see if that helps isolate the problem.

Dynamically Updating Content Server Portlets

[urlHi, I am currently having difficulty dynamically updating content server portlets. I have a portlet of the following form:[/url]
ArticleName Author Title Date mystory author1 title1 04/05/01
story2 author2 title2 06/07/04
story author3 title3 01/02/03
So I have this table where each one of the line items is an article in the content server. So, for example the first line item is an article "mystory" by "author1", with title "title1" and date "04/05/01" additionally there is an article text field, but this isn't displayed unless I click on the article name.
I can set up the basics of this portlet, but when I try to add any real functionality I run into one of two problems.
First Problem: Passing Information
I cannot find a way to pass information between content portlets. For instance, if the user would like to "re-sort" this table based on "date", I would like to have the user click on the "date" column heading and then reload the page. To do so, I would have to pass the section name back to the page so that it could resort based on this data. I have not found anyway to effectively pass information to a content server portlet. I am building these pages through use of the presentation template framework (so I can have access to the content items) but that seems to change the way portlets are handled.
I got around this limitation with a regular portlet by creating an intermediary page which captures passed information and stores it to the session state. Once the information was in the session state, it is accessible to the portlet on the first page. However, this only works because remote portlets do not change their session id once loaded. Content Server portlets, on the other hand, change their session id after every reload of the browser or page change. I can send information from a content server portlet to an intermediary page, but I cannot send it back to the portlet because the session id has changed so I have no idea of knowing where to send the information. I can write it to a session state, but by the time I return to the portal page, the content server has changed its session id so it does not know where to look any longer.
I suppose it would be possible to create an application state variable and append it with some static token (if there is some static variable per portal session) but I would rather not have to deal with application variables if at all possible.
Second Problem: Dynamically Updating PCS Tags
Even if I were able to the pass information back to my content server portlet, I run into another issue. The easiest way to sort content server items is using the filter command in the pcs:foreach tag. So, if I wanted to sort by author name, I could do something like the following <pcs:foreach var="item" expr="filter(folderByName('content'), filtered.name == '"name")" or something like that (the syntax may be incorrect, I just wrote this off the top of my head). However, it appears that the way the presentation templates are compiled goes in the order of PCS tags THEN JSP. So I would have no way of dynamically changing the variable on which I sort. For example, if I clicked on "Date" above in my table, I would like to be able to dynamically change my code so that I sort on date, and not name. I cannot find a solution to this problem.
My workaround is to use the pcs tags to write out all the possible sortings to java array objects. This gives me access to the data on a JSP level and based on whatever the user will chose, I could then display that array. While this works, it is extremely ghetto and inefficient. Any help or suggestions would be fantastic.
Thanks a lot,
Jason Grauel

You can use just about any javascript you want in any Content Server presentation template including ones that are used for portlets.
However, you should be careful to name javascript functions and global variables uniquely so that they do not conflict with any other javascript on the page. To do this, you can append the item id to function and variable names, for example,
function doSomething<pcs:value expr="pcs_id"></pcs:value>() {
return true;

Searching multiple Content Server Portlets

I am able to search single Content Server Portlet and get results using following lines of code.
IPTSession ptSession = new InProcSession();
ptSession.Connect(AppSettings.PTUserName(), AppSettings.PTPassword(), null);
IPTSearchRequest ptSearchRequest = ptSession.GetSearchRequest();
ptSearchRequest.SetSettings(PT_SEARCH_SETTING.PT_SEARCHSETTING_APPS, PT_SEARCH_APPS.PT_SEARCH_APPS_CONTENT);
ptSearchRequest.SetSettings(PT_SEARCH_SETTING.PT_SEARCHSETTING_ASSOC_PORTLET_ID, 10468);
IPTSearchQuery ptSearchQuery = ptSearchRequest.CreateBasicQuery(query, null);
IPTSearchResponse ptSearchResponse = ptSearchRequest.Search(ptSearchQuery);
return ptSearchResponse;
However Type Cast exception comes at run time when we pass array containing multiple Portlets ID although code gets compiled
IPTSession ptSession = new InProcSession();
ptSession.Connect(AppSettings.PTUserName(), AppSettings.PTPassword(), null);
IPTSearchRequest ptSearchRequest = ptSession.GetSearchRequest();
ptSearchRequest.SetSettings(PT_SEARCH_SETTING.PT_SEARCHSETTING_APPS, PT_SEARCH_APPS.PT_SEARCH_APPS_CONTENT);
int[][] ar = new int[2][];
int[] int1 = new int[]{ 0, 10468 };
int[] int2 =new int[]{ 0, 23757 };
ar[0] = int1;
ar[1] = int2;
ptSearchRequest.SetSettings(PT_SEARCH_SETTING.PT_SEARCHSETTING_ASSOC_PORTLET_ID, ar);
IPTSearchQuery ptSearchQuery = ptSearchRequest.CreateBasicQuery(query, null);
IPTSearchResponse ptSearchResponse = ptSearchRequest.Search(ptSearchQuery);
return ptSearchResponse;
It will be quite useful if anyone of you can help us if Plumtree API support this. Or else we need to build another layer to search each Portlet and merge results.

Plumtree Portal 5.0.4

Hi Praveen,
I have not done portal configuration for SAP DMS. But as per the link below, you can assign multiple SAP DMS repository managers which can refer to separate content servers.
http://help.sap.com/saphelp_dimp50/helpdata/EN/32/2a840d132af04fa2f0b31ebf3e8a78/content.htm
Wait for other expert comments if they can answer your query.

In Portal Content admin Role "Portal content" folder is not displaying

Hi,
I created a user in EP and assign Only Content admin Role. But in portal content area "Portal content "folder is not displaying.
Can someone help me the process steps to achieve it?
Thanks,
kundan

It is because the user has no proper permissions to the porta content folder.
you should give atleast read permission to the portal content folder to the content_admin role or to the users who have content admin role.
also make sure the end user check box is checked at the time of giving permissions.
Otherwise give eevryone group as read permisisons to the portal content folder. then you can see the portal content folder with read permissiosn only.

Content server is not running.

All,
I have rather peculiar issue. The external 10.1.3.1 content server is setup against EBS 12.1.3.The content server is running fine and I was able to upload content using it. I fail to upload content all of the sudden until EBS is bounced. Nothing changes on content server side and again it works for day or two and stops and throws "Content server is not running" error. Is there any EBS configuration that can cause this behavior? I do not even see the request being logged in default-web-access-<date>.log on content server that indicates that it is not even reaching content server. It works fine in TEST environment and in PROD it is behaving in this manner. This is a new setup.
Any pointers are appreciated.
Thanks,
Faisal

The fact that bouncing EBS fixes the issue temporarily indicates that the problem is most likely on the EBS end, but we haven't encountered that specific issue. What OS are you using to host EBS? Are you purging the J2EE cache when you bounce the services?
Feel free to reach out to Anne or myself if you'd like to dive into this. We could test with an alternate content server to see if that helps isolate the problem.

After upgrade to 4.0, the controls on mymsn page do not work and several of my content items are not displayed.

The stock quotes, fox sports and movie times content fields do not display and the controls do not work on any of content boxes. The customize and add content tabs do nothing. This all worked with 3.6 but not with 4.0.

A column in the search results was changed to a Simple Checkbox when we upgraded to 4.0 (it has always been a checkbox in the older APEX versions). When I put it back to Standard Report Column I no longer get the page not found error.
Is there some additional/different setting I need to do in order to use the simple checkbox option in a search results set?
ETA: I see now that Checkboxes are not intended to work in standard report regions so I'll change them to LOVs or something and my problem should be solved.

Making a JSR168 Portlet not display due to auths

Hi,
We have a portlet that we'd like to not display based on some authorization business rules. These rules are not based on portal groups (otherwise we could just set the portlet's access through the Builder UI), we need to do this check in java code. So I tried throwing both a PortletSecurityException and a PortletException but neither of these causes the portlet to not display, instead it causes an Error message inside the portlet.
Does anyone have any ideas on how to programmatically make a portlet not display?
Thanks!

How to check file is exists in specified path in content server or not

i m using JDevloper 11.1.1.6.0
I want to upload file using RIDC functions,but before uploading it i have to check wheather it is already present on specified path in content server or not.
How i check it.

I tried to write a (simpler) version of my own code:
    public static Results CheckInToFolder(File f) {
        // create the binder
        DataBinder checkinDoc = idcClient.createBinder();
        // populate the binder with the parameters
        checkinDoc.putLocal("IdcService", "CHECKIN_UNIVERSAL");
        checkinDoc.putLocal("dDocTitle",
                            "Document checked in through RIDC at " +
                            new Date());
        checkinDoc.putLocal("dDocType", "Document");
        checkinDoc.putLocal("dDocAccount", "");
        checkinDoc.putLocal("dSecurityGroup", "Public");
        checkinDoc.putLocal("dCollectionID", "909964822906001607");
        // add a file
        // execute the request
        try {
            checkinDoc.addFile("primaryFile", f);
        } catch (IOException e) {
            myExecutable.logEvent("File" + f.getName() + " not found.");
            return null;
        ServiceResponse checkinResponse;
        try {
            checkinResponse = idcClient.sendRequest(userContext, checkinDoc);
            myExecutable.logEvent("Check-in successful. Size:" + f.length() + " bytes");
        catch (oracle.stellent.ridc.protocol.ServiceException e) {
                        myExecutable.logEvent("ServiceException");
                        e.printStackTrace();
                        return null;
        catch (IdcClientException e) {
            myExecutable.logEvent("Check-in failed.");
            e.printStackTrace();
            return null;
        DataBinder checkinData;
        try {
            checkinData = checkinResponse.getResponseAsBinder();
            Results res =
                new Results(checkinData.getLocal("dID"), checkinData.getLocal("dDocName"));
            myExecutable.logEvent("Successfully got response - dID is " +
                                  res.getDID() + ", dDocName is " +
                                  res.getDDocName());
            return res;
        catch (oracle.stellent.ridc.protocol.ServiceException e) {
                        myExecutable.logEvent("ServiceException2");
                        //e.printStackTrace();
                        return null;
        catch (IdcClientException e) {
            myExecutable.logEvent("Unable to get response.");
            e.printStackTrace();
        return null;
    }What I'm getting is this:
Mon Aug 13 14:51:29 CEST 2012 0ms: Started
Mon Aug 13 14:51:29 CEST 2012 57ms: Connection to idc://192.168.44.129:4444 successfully established.
Mon Aug 13 14:51:29 CEST 2012 102ms: Check-in successful. Size:702 bytes
Mon Aug 13 14:51:29 CEST 2012 5ms: ServiceException2
Mon Aug 13 14:51:29 CEST 2012 0ms: Finished
This means:
a) it does, indeed, return the exception (oracle.stellent.ridc.protocol.ServiceException)
b) you could use this mechanism for your code
c) it is, indeed, primaryFile.name what's being checked
I will also take a look at the other service to perform the check prior to check-in service call.

Content Server Portlet Template Searching

I am trying to use the Community Directory Portlet Template. I basically used it as it came (no editting of templates). I created a couple of folders and added & published content items in those folders.
The problem is that the Search within the portlet is not returning anything (even searching for '*') returns nothing.
Is there some setting I missed or something? I've tried publishing the whole folder from Content Server Explorer and still no luck. Searching for text in the published items from the Content Server Explorer does work, but searching from the portlet does not.
Thanks.

Hi Raj ,
ORA-01013: user requested cancel of current operation error comes up usually in 2 cases :
1. When CS is losing DB connection intermittently
2. DB is timing out with the queries being fired from the UCM
Add the config variable DatabaseConnectionKeepAliveInterval=300 (for SCS to send Keep Alive Packet to the network so that the connectio drop is avoided)
The value provided is ins secs.
Secondly drop / rebuild the indexes for the following tables :
DOCMETA , COUNTERS, DCOUMENTS , REVISIONS
Then execute the statistics procedure on the DB so that all the indexes are updated with the latest db stats.
Test to see if the issue still persists.
Hope this helps
Thanks

JavaScript and Content Server Portlets

Header, footer, news, custom, doesnt matter. Can you use javascript in them and if so, to what extent? For mouseovers, animation, div tag management and manipulation, etc...

You can use just about any javascript you want in any Content Server presentation template including ones that are used for portlets.
However, you should be careful to name javascript functions and global variables uniquely so that they do not conflict with any other javascript on the page. To do this, you can append the item id to function and variable names, for example,
function doSomething<pcs:value expr="pcs_id"></pcs:value>() {
return true;

Content management portlet not showing images

Hi all,
sorry for asking a question maybe already answered, but I couldn't find a solution in the newsgroups.
I'm trying to use the content management portlet provided with Bea WLP 8.1 SP4, but I've a problem with the images (they're not displayed at all, only a lot of red "X"s).
I followed the instructions in the help of workshop, so I think I've imported every needed files. Moreover, the images are in the right folder tree.
Any help for a completely newbie???
Thx in advance,
Mirko.

Hi Mirko,
I was having that same problem, and I couldn't find anything on this website either. I tried creating a new portal project and following the directions exactly again, but it didn't work there either. It works in the sample portal.
So I contacted BEA Support, and they were able to provide me with a solution:
The file url-template-config.xml (in the WEB-INF directory) has to be modified and have the {url:currentPage} parameter removed in order to get the images working for the content management portlet. For now, do this only in the section . Leave the other places like in WSRP etc as it is.
I actually took it out of the WSRP places too, by accident, but I don't use WSRP anyway, and everything else seems to be working fine. And the images show up!
Hope this works for you too,
Beth

Link to content area - portlet not available

I have a link to a content area in that I open from another application. Occassionally, I get a "portlet not available" message. Is this related to navigating directly to the document repository? It works most of the time.
So 3 questions:
Is it acceptable to navigate directly to the content area? (My users then log on and store documents)
Am I getting the "portlet not available" message because of navigating to the content area this way?
Is there another reason I'm getting this message?
Thank you

Unfortunately, the only way to do this would be to not show the sub-folder region and add URL items in another region that link to the folder page in question.

Content Server Settings not working (for PPM)

Hi,
We are on PPM5.0.
We have set up the Content Server settings according to the PPM
configuration guide.
We, however, still see the documents (uploaded in the project) showing
up on the PPM Server.
We checked the entries in table CFF_CONT (in the PPM server), and see
the contents updating when a document is uploaded. This makes us
conclude that the documents are still not being stored on the Content
Server.
Any switch/flag that needs to be set/reset in the WAS and/or Content Server that'll help??
Or anything else...???
Thanks.

Earl Powers BSR2751547 Thank you all. your suggestions really helped.

Dynamic page in region as a portlet not displaying in portal template

As the title suggests I have a portal template that contains a region at the top . within this region i have included 2 portlets, first is a dynamic page (a simple banner title ) then a navigation page beneath them .
when I am logged in as a specific user it displays correctly , when I log onto the page without logging in - the dynamic page does not display ,yet the navigation page does . I have clicked on every display to public check box , assigned public user with view privilege and everything else along those lines . Any ideas ??
thanks in advance , Chris

Hi Chris: Just to be specific, did you go to the providers tab in Navigator, the locally built providers link then the provider which contains your dynamic page and check the access set directly on that page? You can either set the dynamic page to have its own access (overriding that of the provider) or set the provider itself to be public.

Report deployed to new server does not display static image

Hi,
We have several web sites on a server running Windows Server 2008 R2 Standard, SP1, 64-bit. It has installed .NET Framework 4 Client Profile and Extended, ver. 4.0.30319 (according to Control Panel->Programs, as well as c:\Windows\Microsoft.NET\Framework). Two of the sites use many Crystal Reports, most of which include a static image as a logo. This image is embedded in each report; there is no stand-alone image file that gets deployed.
Recently, we migrated to a new server, running the same version of Windows & .NET Framework. As near as we can tell, the 2 servers are nearly identical, as far as configuration and permissions, etc. One notable exception is the DefaultAppPool, which is Classic on the original server and Integrated on the new. (When I changed the new server to Classic, the apps failed to run properly.) The other exception is the old server is on a stand-alone box, while the new server is a virtual machine.
For one of the apps on the new server, the embedded logo images are not displaying on the page. Instead, there is a little red X with the word "Image". For the other app on the new server, the reports display fine. Furthermore, if I copy one of the "broken" rpt files from the "broken" app to the "good" app, the report displays correctly! And of course, the same file displays correctly in all circumstances on the old server.
This suggests to me that there is not a problem with the report file, per se', but rather with the environment to which it is deployed. Permissions? If so, where?
Any suggestions would be much appreciated.
Thanks.
--d

The search string 'crystal red x net' (search box in top right corner) should return a number of KBAs, docs, blogs, etc. See if any of those help.
