Retriving Portlet preference information using a custom tag

Hi ,
I am trying to create a custom tag which will be used to retrieve portlet prefrence information (administrative pref, community pref, user pref etc.).
In the displayTag method i am not able to create the Portlet request object.
I am getting the IEnvironment reference by calling the method GetEnvironment().
IEnvironment has methods called currentHTTPRequest() and currentHTTPResponse() which returns IXPRequest and IXPResponse object,
But to create a portlet context I need HTTPRequest and HTTPresponse.
If some one is aware of any other method for creating the portlet context from IXPRequest and IXPResponse object. please share as it will be of great help.
Thanks in advance!!

Thanks for reply!
Actualy I am trying to retrieve the Prefernces ( Community Preference, User Preference, Administrative Preference ) values in a custom Tag.
But I did not find any way in native APIs to retrieve the preferences.
So I was wondering if somehow I can established a remote session using IDK to retrieve the same.

How could I get all the entries in LDAP that matches entries with first name or second name or the employee number(if user the number for sure).
Any sample program would help more.

How to use JSP custom tag lib in PAR file?

Hi All,
I am trying to customize mastheaderpar file. For that I have downloaded relevant par file and making the changes accordingly.
As part of the changes I would require to use JSP custom tag library in my par file.
I have the TLD file and relevant classes in the jar file. I would like to know where and what kind of modifications have to be done to use the jsp custom tag library.
I tried modifying some things in portalapp.xml but was not successful.
Please help me on how to proceed with this? It would be great if you can provide the xml entry to use this tag library
Thanks

Hi Johny,
Thanks for the reply. Actually I am able to change colors etc. with out any problem.
My requirement is to use XMLTaglib in mastheader par file. This tag lib is from apache tomcat. I have the relevant TLD and class files. I copied TLD file into taglib dir of portal-inf and class file in src api.
And I have added the following line in portalapp.xml under component-profile section of default
<property name="tlxtag" value="/SERVICE/Newmastheader/taglib/taglibs-xtags.tld">
Is this the right way to use tag lib? Actually before adding this line I used to get the error saying "Error parsing taglib", but now the error does not occur and I am getting new error. This is an exception in one of the taglib classes.
Could any one provide me some inputs on how to check this error?
Thanks

Using a custom tag with a 2.3 servlet descriptor BUG?

Hi,
I just developed a Custom Tag and I'd like to use in my jsps.
If I add the jsp in my JDev project with the custom tag when I try to build the project I got this error:
Error(11): oracle.xml.parser.v2.XMLParseException: Invalid element 'listener' in content of 'web-app', expected elements '[context-param, servlet, servlet-mapping, session-config, mime-mapping, welcome-file-list, error-page, taglib, resource-ref, security-constraint, login-config, security-role, env-entry, ejb-ref]'.
It seems like when the jsp parser encounters the line with taglib it tries to parse the web.xml against a 2.2 version of the dtd. My web.xml begins with the correct dtd version (2.3). Can anyone tell me if this is a bug and eventually tell me how to solve it?
thanks,
Giovanni

I repost this issue again, now with a simple test case.
If I wrote a simple custom tag:
import java.io.IOException;
import javax.servlet.jsp.tagext.TagSupport;
public class MyCustomTag extends TagSupport {
public int doStartTag() {
try {
pageContext.getOut().print("FOO");
} catch (IOException ioe) {
pageContext.getServletContext().log(ioe.getMessage(),ioe);
return(SKIP_BODY);
with the associated tld:
<?xml version = '1.0' encoding = 'windows-1252'?>
<taglib>
<tlibversion>1.0</tlibversion>
<jspversion>1.2</jspversion>
<shortname>try</shortname>
<uri>try</uri>
<info>A short description...</info>
<tag>
<name>mytag</name>
<tagclass>MyCustomTag</tagclass>
<bodycontent>EMPTY</bodycontent>
</tag>
</taglib>
and a jsp using the custom tag:
<%@ page contentType="text/html;charset=windows-1252"%>
<HTML>
<HEAD>
<META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=windows-1252">
<TITLE>
Hello World
</TITLE>
</HEAD>
<BODY>
<H2>
The current time is:
</H2>
<P>
<% out.println((new java.util.Date()).toString()); %>
<%@ taglib uri="try.tld" prefix="try" %>
<try:mytag />
</P>
</BODY>
</HTML>
all runs fine if I have a web.xml with the dtd version 2.2
<?xml version = '1.0' encoding = 'windows-1252'?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN" "http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">

I get the error I report in my last post. (the jsp doesn't compile) If I remove the custom tag from my jsp all works fine (filters, listeners,etc). In my project settings I use the 2.3 version of servlet.jar instead of the ServletRuntime that comes with JDeveloper.
Can anyone tell me how to resolve this issue (Using simple custom tag with a web application using the 2.3 servlet specs)?
Thanks in advance,

Re: Using ScopeCache custom tag

Hi, I am quite new to ColdFusion and I have a calendar that
is quite slow due to the cfloops it uses to build the calendar. As
the page does not change very often I wanted to use Raymond

Hi, thanks to both of you for your help. I reverted back the
custom tag and it was picked up this time - I don't know what
happened before. The functionality works as expected but I have hit
another problem and I am hoping I can tap your combined ColdFusion
wisdom to solve!!
The calendar returns leave records for staff and filters the
records using a querystring variable appended when the user clicks
on a particular month. However, what members of staff the user sees
depends on the data held in the users' session variables based on
their authority. The reason I wanted to use caching is because the
page takes a good ten seconds to run because of the use of cfloops
for the members of staff and the days of the week to dynamically
build the page. Using the custom tag would have worked if all
members of staff saw the same calendar data and could only see one
month. Can you see anyway I can speed up the page and do you think
caching is the way forward here?

Cannot use cfx_image custom tag

While trying to use cfx_image tag I am getting the following error and anyone give me an idea what I am missing?
Thanks

Yes there was a problem with bits. I was trying to run a 32bit dll in 64bit CF.
Fix:
Rather than reinstalling my CF I gave up using cfx_image tag as I found a better option.
The builtin CF function ImageResize:

<cfset uploadedImage=ImageNew("#attributes.imagepath#\#photo#")>
<cfset ImageResize(uploadedImage,"#attributes.thumbsize#","","highestQuality",1)>
more details about this function can be found at:

How do I configure portal desktop to use my own custom tag in template?

I seem to have tried everything. I want to use a custom tag from a jar file on a template JSP. I keep getting error saying tag library not found. I have the tld in the meta-inf of the jar. I tried putting the jar in the desktop classes, the deployed WEB-INF lib directory for portal, in the web-src directory for the portal. I tried configuring the uri in the web.xml for the portal webapp. None of these have worked. Does someone know how to do this? If someone could help out that would be great. I tries the jar from a web application and it worked fine. I just need to get this working with Portal Server.
Thanks,

Thank you for the reply Alex. We are using the Dynamics AX 2012 R3 ISO for our installation. In the software requirement documentation for Dynamics AX it says that is able to run on Windows Server 2012 R2. I believe the prerequisites for Dynamics AX and
Dynamics CRM are different. We received a response from another forum that you can change the .NET version that Sharepoint 2010 uses through IIS in the application pool, but even after setting it to .NET v2.0, we still receive the error in the Dynamics log
that says it is not compatible with .NET v4.0. So I suppose the question is, where does the Dynamics AX 2012 R3 prerequisite checker look to see which version of .NET Sharepoint is using?
Thanks again for the reply!

How can I use evaluate to get the instance variable in customized tag

1.
At first , I create a class called bean,and declared several params in it and do not define any getter function for the param.
class bean{
String param = "test";
SomeClass scObj = new SomeClass();
2.
The second ,I use
request.setAttribute("beanObj",new bean());
3.
And then I wanna use the customized tag to show a text box , then initialize it's value.
<salt:text name="param" value="beanObj.param">
<salt:text name="obj" value="beanObj.scObj.func()">
4.
I tried the evaluator provided by JexlContext ,Struts, JSTL and it seems that if I do not define the getter for the variable ,I can not get the bean's instance variable's value.
Expression e = ExpressionFactory.createExpression( value );
JexlContext jc = JexlHelper.createContext();
jc.getVars().put(strInitBeanName, request.getAttribute("beanObj"));
Object obj = e.evaluate(jc);
the result of the obj is null....
Can anybody recommand some other evaluator can get the value of a instance variable from an object?

do you have any other suggestion ? Nops, somebody else may have though. AFAIK, all lookups of the type
beanName.propertyNameuse reflection on the getXXX() methods to access the property.
Having said that, I guess you could write one though in a custom tag, using the same - reflection (you will ahve to rely on the java.lang.reflect.Field class quite heavily) - but that would be reinventing the wheel for most other functionality that you would have to include (like looking up the bean in scope etc)

How to use Custom Tags for Theme and Base Map Definitions

In Mapviewer documentation I've found the following new feature:
The XML definition of a theme or base map now supports application-specific
attribute tags. You can use the Custom Tags option in the theme definition in Map
Builder to specify tags and their values, which can be interpreted by your application
but are ignored by MapViewer itself.
I'm able to define a custom tag in Mapbuilder, but how can I use it in my Application?
Thanks.

As he said, you have to use as Platform service to create adapter in OIM.
tcUserOperationsIntf service = Platform.getService(Thor.API.Operations.tcUserOperationsIntf.class);
HashMap<String,String> searchmap=new HashMap<String,String>();
searchmap.put("Users.User ID", userID);
tcResultSet searchset=service.findAllUsers(searchmap);

Error Using Custom Tag

I am trying to use a custom tag but receive an error when I use it on a jsp page.
I have a tag handler class file, tag library descriptor file, specified the path to the .tld in the web.xml file.
The error implies that it cannot find the SimpleTag.class file, though I put it in the \webapps\examples\WEB-INF\classes\ directory.
Here is the error. Does anyone know what else it could be?
org.apache.jasper.JasperException: Unable to compile class for JSP
Generated servlet error:
C:\jakarta-tomcat-4.0.1\work\localhost\examples\jsp\jspVisual\ch10\using_0005ftag$jsp.java:63: Class org.apache.SimpleTag not found.
SimpleTag_jspx_th_myFirstTag_SimpleTag_0 = new SimpleTag();

I could not see any obvious mistakes. But what you could try, in order to isolate the problem, is to bypass the web.xml. In other words access the TLD directly by doing this in your JSP
<%@ taglib uri="/WEB-INF/jsp/tag_library_descriptor.tld" prefix="myFirstTag" %>
if that does work then move the your TLD out of the jsp folder and into WEB-INF , then try
<%@ taglib uri="/WEB-INF/tag_library_descriptor.tld" prefix="myFirstTag" %>
Maybe someone else has better idea.

IllegalStateException using custom tag

I'm receiving the following exception when trying to use a custom tag we are developing to allow us to provide localized content based on the users browser language/country settings:
     java.lang.IllegalStateException: WEB3025: Cannot reset after response has been committedThe thing is - the tag works perfectly when the page is using JSP includes:
     <jsp:include page="/components/headers/global.jsp" />but we get the exception when using our tag:
     <core:localizedInclude page="/components/headers/global.jsp" />and we make a call to our servlet:
     <jsp:forward page='/servlet/MyServlet' />Here is the line in the custom tag Java code that pulls in the file:
     pageContext.include(localizedPage);Any ideas what we can do to fix this? What are the differences between the <jsp:include> and our <core:LocalizedInclude> in this case?
Bob

The pagecontext 's include method flushes the buffer before a call to this method. This means the call to your tag from the jsp should be the first line in your jsp as headers have to be set first before writing any html response.
Here's the relevant javadoc.
blah..blah..
The current JspWriter "out" for this JSP is flushed as a side-effect of this call, prior to processing the include.
blah..blah..You could try the overloaded pageContext.include("path", false) which according to javadoc
blah..blah..
If flush is true, The current JspWriter "out" for this JSP is flushed as a side-effect of this call, prior to processing the include. Otherwise, the JspWriter "out" is not flushed.
