JspDynPage Problem
Hi,
I have developed an 2 applications.
1st application i have developed a custom tag.
2nd application i want to use that customal tag.
code in portalapp.xml:-
<component-profile>
<property name="cust"value="/SERVICE/customtags/taglib/lokesh.tld"/>
</component-profile>
here "customtags" :- is my application name.
If anyone could help me how the application is being stored when we deploy?
I mean to say the path where my application is being stored in the server.
Because here i am refering the previously loaded PAR.(i mean to say the application PAR).
lokesh.tld is my TLD file
code in my JSP page :-
<%@ taglib uri= "cust" prefix="mtags" %>
<mtags:lok/>
here lok is the name of my tag
Now my error is when i am deploying it is sowing the error
"java.lang.NullPointerException".
and also what is the meaning of "SERVICE"?
Please explain me that?
Thanks & Regards,
Lokesh

JSPDynpage problem...plz help
Hi All,
I hv a Strange problem facing with Portal Component Project. I hv created Portal Component Project with two JSPDynpages :
JSPDynpage1 - hving one Hyperlink Text
JSPDynpage2 - Plain text and Images
Whenever User clicks on Hyperlink in JSPDynpage1 will navigate to other JSPDynpage which show only plain text and images.
I hv used following h ref to navigate from one to other
href="http://someserver:50000/irj/servlet/prt/portal/prtroot/PDK
Project.JSPDynpage"
I hv created an IView based on JSPDynpage1. Everything works fine. IView is
showing the Hyperlink and taking it to the next page. Finally I assigned this IView to page.....when the User clicks on Hyperlink it is prompting me give User Id and pwd.
Also, Hyperlink shows underlined eventhough when I don't point mouse at hyperlink. I want to get rid of this one.
Can anybody help me in this regards.... where I am going wrong. Any suggestion woudl be greatly appreciated and helpfull. Looking forward to your responses.
Thanks in advance,
Ravi Kumar.Hi Ravi,
please check the permission property for the target iView: Right Click open -> Permissions. If you see the permission is only given for super admin or something like that then add the Everyone gorup to it and check on the End User checkbox. Save the permission set and then test to see what happens.
Regarding the line coming below hyperlink - I think you need to change the design of the link a bit in order to get the hovering effect.

Problems using a static class extending JSPDynPage
When I use the pdk with netweaver for creating a new portal object and I want to create a new PortalComponent (JSPDynpage) the pdk generates me the next code:
public class TestJspDynPage extends PageProcessorComponent {
public DynPage getPage(){
return new TestJspDynPageDynPage(); }
public <b>static</b> class TestJspDynPageDynPage extends JSPDynPage{
public void doInitialization(){ }
public void doProcessAfterInput() throws PageException {}
public void doProcessBeforeOutput() throws PageException {}
Is there any reason for creating the new class that extends JSPDynPage static ?
Regards.Hi,
That is a common problem, all variables in your JSPDynPage, should be saved in IPortalComponentSession/HttpSession instead of having instance/class variables.

Problem getting jsp component from jspdynpage
Hi,
I am making a call in my java class in method
doProcessBeforeOuput with the following call
table = (TableView) this.getComponentByName("tableview_AddMaterial");
Object[] objs = this.getComponents();
Both return nulls for the object, how does someone access the jsp tables or text fields defined by id in htmlb in your java code I did check and all these are defined
private IPageContext pageContext;
private IPortalComponentRequest request;
private IPortalComponentResponse response;
private IPortalComponentSession session;
private IPortalComponentContext userContext;
private IPortalComponentProfile userProfile;
Also here is my htmltable in the jsp
<hbj:tableView
id="tableview_AddMaterial"
model="DHB.queryResultsModel"
design="TRANSPARENT"
headerVisible="false"
footerVisible="true"
visibleRowCount="50"
visibleFirstRow="1"
selectionMode="MULTISELECT">
</hbj:tableView>
Any help would be greatly appreciated and I do reward points for helpful answers
Cheers,
DevlinHi Devlin
You can access the fields in jsp as follows.For example, consider tableview with id "myTableView".
<b>TableView table = (TableView) this.getComponentByName("myTableView");</b>
If you add this line, you can get all the values related to tableview.For example, to get the first visible row of the tableview, the code goes as follows.
<b>int firstVisibleRow = table.getVisibleFirstRow();</b>
Jsp for the same:
==================
<hbj:tableView
id="myTableView"
model="tablebean.model"
design="ALTERNATING"
headerVisible="true"
footerVisible="true"
selectionMode="MULTISELECT"
headerText="Office locations"
visibleFirstRow="1"
visibleRowCount="5"
rowCount="16"
width="500px">
</hbj:tableView>
Try and let me know the results.
Hope this helps.

Export to Excel & Download in JSPDynpage
Hi All,
I have developed one JSpDynpage application in which I am displaying the custom portal activity report on portal page. I . I have used normal HTML code in JSP file. Now I have to export this data in Excel sheet & Download it.
For this I have gone through these steps.
1) As per the few suggestions on SDN , I have created seperate AbstractPortalComponent for this functionality.
2) I have followed prakash's blog i.e. Create an excel file from JAVA using HSSF api
3) Included all needful POI jar files mentioned in the blog.
But still i am getting error - java.lang.NoClassDefFoundError: org/apache/poi/hssf/usermodel/HSSFWorkbook
This class exists in JAR file when i checked. Error is looking simple, but not getting resolved.
Also please suggest me -
1) How to call this AbstractComp. from JSP file , when user click on a link on portal page.
2) what shoud be the additional code for download functionality?
Any sample code will be more helpful
Regards,
VishalHi Vishal,
I am facing one problem with customization of portal activity report.
We made some changes to the existing report par file and deployed from NWDS to dev system. When we previewed the existing iview in Dev portal system the changes reflected and once we exported the PAR file to QA system and previewed the iview from portal, there is no data coming to portal.
Can you please let us know what could be the reason for this?
Thanks

Error while using jsp scriptlet or expression with JSPDynpage default jsp
Hi everyone,
I am getting the following error while trying to use any kind of jsp scriptlet or expression within the default jsp page that is created with JSPDynpage application:
Portal Runtime Error
An exception occurred while processing a request for :
iView : Navroz_JSPDynPage_JCo_BAPI_FLCUST.FlightCustJSP
Component Name : Navroz_JSPDynPage_JCo_BAPI_FLCUST.FlightCustJSP
Error occurs during the rendering of jsp component.
Exception id: 08:50_05/10/06_0032_17543050
See the details for the exception ID in the log file
For example if I try to use even simple syntax like:
<% if(true) { %>
display htmlb tableviewcomponent
<% } %>
or
<hbj:tableView
id="myTableView"
model="flightCustomer.model"
design="ALTERNATING"
headerVisible="true"
footerVisible="true"
fillUpEmptyRows="true"
navigationMode="BYLINE"
selectionMode="SINGLESELECT"
headerText="Flight Customer List"
onNavigate="Navigate"
visibleFirstRow="<%=flightCustomer.getVisibleFirstRow()%>"
visibleRowCount="5"
rowCount="16"
width="500 px"
/>
here also the <%=flightCustomer.getVisibleFirstRow()%> line gives the above mentioned error. If I remove such scriptlets or expression then it works fine.
What could be the problem. Are jsp scriptlets or expressions incompatible with portal applications?hi Navroz,

RudraHi,
I am still having the same problem, however the scenario in which I am getting varies.
I am getting this exception:
"com.sap.engine.services.webservices.jaxm.soap.accessor.NestedSOAPException: IOError while working with the message."
Some users when trying to login into the portal are getting blank screen and for some the portal launcher page is loading fine and could go to the Home Page.
When I view the logs I am seeing the Nested Soap Exception.
Any Ideas??? Starting the J2EE engine also did'nt help.
Thanks in advance.

Warning message due to JSPDynpage
Hi All,
We have a scenario where in the jspdynpage we have only hyperlinks and One of the hyperlink is pointing to the standard uwl iview as follows
[http://portalhostname:50000/irj/servlet/prt/portal/prtroot/pcd!3aportal_content!2fcom.sap.pct!2fevery_user!2fgeneral!2fiViews!2fcom.sap.netweaver.bc.uwl.iviews!2fcom.sap.netweaver.bc.uwl.uwl_iview?sap-config-mode=true|http://portalhostname:50000/irj/servlet/prt/portal/prtroot/pcd!3aportal_content!2fcom.sap.pct!2fevery_user!2fgeneral!2fiViews!2fcom.sap.netweaver.bc.uwl.iviews!2fcom.sap.netweaver.bc.uwl.uwl_iview?sap-config-mode=true]
We are on CE7.1 and whenever I click on this hyperlink of jspdynpage, the uwl iview opens but with a warning msg at the header of the UWL as follows
"Another administrator is currently customizing this application. If you want to customize, please restart the application later and try again"
Same UWL iview when I open thru Home ->Work->UniversalWorklist , it does not show this warning message.
Is it bcoz of any session object inthe jspdynpage? any pointers will be of great help.
one note & Observation
assume that all the users are logout from the portal now any user first logged into the portal then that warnong message is not displayed at the header level of the UWL iView which we are accessing thru the hyper link from the JSPDynpage . but second user onwards any number of users are logged into the portal and click on the hyperlink in the JSPDynpage and it goes to UWL Iview where it is showing the above mentioned warning message at the header level. it is happening the same for the second user, third user and all users consequently but this warning message is not displayed for the very first logged in user.
Can anybody replys then it would be great help to us . <<text removed>>
when we access those links directly from the browser it is not giving that above specified warning message but this warning message is getting displayed when we access those hyperlinks from JSPDynpage .it seems there is some session related problem or something related to that. pls help.
Thanks

Problem using target="_blank" in hbj:link
Hello,
we are having some problems when using "link" with the next piece of code:
<hbj:link id="<%=objAccountStatus.getAccountNo()%>" text="View Inventory" tooltip="Download as an Excel Spreadsheet document" reference="" onClick = "onInventoryLinkClick" target = "_blank">Download Excel</hbj:link>
The target is set to _blank but the Excel generated by using the link is opened in the same page. This problem occurs by using the Internet Explorer; on the other hand, this works fine in Firefox (in this case is opened in a blank screnn.
Thanks in advance.
Regards,
Raúl.Thanks for you reply Pankaj, but the version I am using is IE 6.0.29.
I have fixed the problem by modifying some code used in the event handled in the JSPDynPage becuase we were doing some things in the HTTP header that could have destroy the effect of the "target" parameter in the link.
It was solved by other way.
Thanks a lot for the help.
Regards,
Raúl.

Problem in exchange data using Bean
Hi all,
I have a problem when creating a portal application.
I've done through the steps described in this link:
http://www.ajvic.es/irj/portalapps/com.sap.portal.pdk.htmlb.htmlbmanuals/docs/dynpage-01.html
In this example, I use bean to exchange data.
In the function <b>doInitialization()</b> in JSPDynpage.java:
public void doInitialization()
// create the bean and set a default text value "unknown user
IPortalComponentRequest request = (IPortalComponentRequest) this.getRequest();
IPortalComponentContext myContext = request.getComponentContext();
IPortalComponentProfile myProfile = myContext.getProfile();
// new bean object
UserNameContainer = new DynPageNameBean();
// set default name
UserNameContainer.setName("unknown user");
// store bean in profile for the JSP
myProfile.putValue("UserNameBean", UserNameContainer);
// Now we set the state so that we can decide what action to do next
state = INITIAL_STATE;
The code: <b>myProfile.putValue("UserNameBean", UserNameContainer);</b> give a warning: "The methode getValue(String) from the type IPortalComponentProfile is deprecated" and I see that the value of UserNameContainer is <b>not</b> assigned to "UserNameBean".
If I use this code:
UserNameContainer = (MyBeanClass) myContext.getValue("MyB");
UserNameContainer.setName(name);
The result is the same.
Do you know how to solve this problem ?
Thank you in advance & kindly regards.
TweetyHi
Here is what you should do.
First The Bean
public class UserBean implements Serializable {
private String name;
public String getName() {
return name;
public void setName(String string) {
name = string;
Next the Dynpage DoInitialization Method .
IPortalComponentRequest request =
(IPortalComponentRequest) this.getRequest();
UserBean myBean = (UserBean) request.getComponentSession().getValue("myBean");
if (myBean == null) {
myBean = new UserBean();
myBean.setName("Unknown User");
request.getComponentSession().putValue("myBean",myBean);
this.state = INITIAL_STATE;
Next the JSP
<%@ taglib uri="tagLib" prefix="hbj" %>
<jsp:useBean
id="myBean"
scope="session"
class="UserBean"
/>
<html>
<hbj:content
id="myContext">
<hbj:page
title="PageTitle">
<hbj:form
id="myFormId">
<hbj:textView
id="s1" >
<%
s1.setText(myBean.getName());
%>
</hbj:textView>
</hbj:form>
</hbj:page>
</hbj:content>
</html>

Axis Problem while using Quick Address

The qas.proweb package is a third party code in a jar file imported in the Project developed in Netweaver and it compiles and executes fine but this is the error it gives us in the log, showing some problem with the connexion. This qas.proweb runs by using SOAP and probably the problem will be some compatibility issue with this in the Portal.
The code used in the JSPDynPAge to acces qas.proweb is the same as the one working in a Java program with a main method requesting data against the same machine.
It could be some issue with axis and the SAP Portal.
What do you think about this error??
Thank you in advance.

Raúl.I solved the problem by installing only the JAva part, without the ABAP part.

How to call the Jsp file in JspDynpage

Store Client - strange problem
Hi
I've problem with store client. It open and function OK (I can search for files, change settings etc but it dosnt download files)
Today I've downloaded many files with it (about 20) and all works fine but on the last 5 files it has stopped and nothing happens (seems like server on the other side is off) All other applications and connections works fine
I try many things (reinstall app, restart phone) without succsesHello All,
Thanks for the reply. The problem got solved. There was a bug in the controller program. The JSP part is working fine now. Now I am facing another issue. The bean that i am having in the session is not available in the result jsp.
The following are the piece of codes that i use for session tracking..
JSPDynPage: doInitialization()
IPortalComponentRequest request = (IPortalComponentRequest)this.getRequest();
IPortalComponentSession session = request.getComponentSession();
dataBean = new FR100Class();
session.putValue("clientData",dataBean);
and I am setting few values for the Bean in the onClick event of JSPDynPage and few by calling an external java class say c1 by passing this bean instance to c1's void method(doesn't return any value).
Initial JSP:
<jsp:useBean id="FR100Bean" scope="session" class="com.test.fr100.FR100Class" />
Result JSP:
<jsp:useBean id="FR100Bean" scope="session" class="com.test.fr100.FR100Class" />
Here when i tried to read FR100Bean.getName() it returns null.
Where have i gone wrong?
Thanks in advance.

I have been trying to get a tableview to be sortable by clicking on the header of columns. I have been reviewing existing threads on the forum in particular the one below.

Any help would be greatly apprciated and rewarded...Hi Don,
be aware that after the method onHeaderClick(Event event) is executed the method doProcessBeforeOutput() is executed as well.
I look over your code and found the following:
1) In method onHeaderClick you sort the table model and store the table model in the bean
2) In method doProcessBeforeOutput() you create a new table model from scratch (in helper method tableViewFormat())and store it in the bean. Thus you overwrite the sorted model.
I suggest that you move the initial creation of the table model in method doInitialization(). Do not forget to store the created table in the bean. In method doProcessBeforeOutput() you retrieve the table model from the bean instead of creating a new one for every request.
Best regards,
Martin
