Seam tags in custom tag libs

Hi,
Can't we use seam tags inside Java class ?
I need to create a custom tag using seam tag <s:link />
stringbuf.append("<s:link id=\"sample\" view=\"/sample.seam\" value=\"Sample123\" propagation=\"none\"/> ");
The below given code is not giving me a link in the UI. While taking source from the UI the <s:link /> tag is not converted into html <a href >.
What should I do to get a link by <s:link> using as a custom tag ?

Sorry, wrong forum, should be in the JSP forum. Hope someone can still help!

How can I evaluate custom tag in custom tag output.

Hi,
          I have a custom tag which returns the following String
          <html>
          Hello there <util:getName/>
          </html>
          Currently the <util:getName/> just prints to the html page. What I
          want is for that tag to be evaluated. Can this be done?
          So in my first jsp, I have the following:
          <cache:getHtml/>
          This cache:getHtml is the tag above that returns the chunk of html.
          The reason that I want this done is that the html is created by an
          xslt transformation but I cache the result of this transformation but
          I need the result to contain some dynamic data so if I could get the
          custom tag to work that would be ideal.
          Thanks in advance,
          IH

Custom tag error

I'm tring to create a new JSF custom tag. my custom tag inherits from another custom tag called tab.
the tld look like this :
<taglib>
<tlib-version>1.0</tlib-version>
     <jsp-version>1.2</jsp-version>
<short-name>actab</short-name>
<uri>http://jsftutorials.com/</uri>
<tag>
<name>actab</name>

     </attribute>
<attribute>
          <name>id</name>
     </attribute>
</tag>
</taglib>
I'm tring to use the custom tag in the jsp, when I specify the attrbute name I get the following error:
monolithic.jsp(14,13) Attribute name invalid according to the specified TLD
when I remove the name attribute from the jsp I get the following error :
monolithic.jsp(13,10) According to the TLD attribute name is mandatory for tag actab.
does anyone have an idea about what the problem is ?

a bit more info required I think.
Is there more to that exception than you posted - coming from your code?
Maybe you can put try/catch code in your Tag source file to catch and print any exceptions that occur.
Beans property conversion would indicate that it has translating one type to another.
What attributes does this tag take. Should width be an integer - and 96% causes it an error?
Lets see the tld file, and maybe some basic source?

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
Santhosh

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
Santhosh

Hi,
Make sure you have the JSTL tag library selected in you deployment plan. Go to Project Properties->Deployments->your_deployment_profile->WWB-INF/Lib Contributors and check JSTL.
Let me know if this worked for you!

Custom tag lib, tomcat server cant parse descripter file

Hi there, I'm working on custom tag libraries, and I have created a simple tag which prints a string when it is called from a jsp file. And I have created a descriptor file for that perticular tag and also created a jsp file which is using the tab lib that I have created, I have placed all these files in their corresponding files, well the problem is when I'm trying to call that jsp file it says the server can't parse the tags.tld file, because <urn></urn> must be declared.

I guess tag urn is not required.
Hope this helps

Custom tag lib with output parameter

Hi,
I need a tag libray that gives me a specific element of a Vector.
Here there is the line I have in my jsp.
<ct:partizione tronco="${contenitoreCentralineTronco}" indice="index" partizione="tmpPartizione"/>
...-contenitoreCentralineTronco is an Object that contains a Vector of other specif objects.
-indice is the vector index of the specif instance I need.
-partizione should be the output instance.
This is part of my tld file:
    <tag>
         <name>partizione</name>
        <tagclass>ss.aspi.classi.centraline.grafica.tagSupport.Partizione</tagclass>
        <bodycontent>empty</bodycontent>
        <info>Estrae una partizione da un vettore di partizioni dato l'indice</info>
        <attribute>
            <name>tronco</name>
            <required>true</required>
            <rtexprvalue>true</rtexprvalue>
        </attribute>
        <attribute>
            <name>indice</name>
            <required>true</required>
        </attribute>
        <attribute>
            <name>partizione</name>
            <required>false</required>
        </attribute>
     </tag>
...this is part of the class called by the tag:
     private ContenitoreTroncoBean tronco;
     private Integer indice;
     private ContenitorePartizioneBean partizione;
     public int doStartTag() throws JspException {
          try {
               Vector<ContenitorePartizioneBean> partizioni = tronco.getPartizioniBean();
               partizione = partizioni.get(indice);
          }catch (Exception e) {
               log.error("Errore nell'estrazione della Partizione "+indice);
               e.printStackTrace();
          return TagSupport.SKIP_BODY;
     //All getter and setter functionsWhen I run the application I get this exception:
jsp.error.beans.property.conversion
looking deeper in the class code jenerated from the jsp, I noted that the problem refers to the third attribute of the tag <ct:partizione>.
It seems It trys to set the attribute "partizione" with the value "tmpPartizione", but partizioni should be an output attribut non input. The varible tmpPartizione doesn't exist... the tag should create it.
I realized I didn't get how I should create a tag with output parameters.
Anyone can explane me it?
Thanks.

One suggestion: Take a closer look at the EL (expression language)
It has an excellent syntax for accessing collections/maps
${contenitoreCentralineTronco[index]} would exactly what you want, without having to write a custom tag for it.
If you REALLY want to do this as a custom tag, then you need to treat the input attribute as a String (the name of the variable you are going to create?) Right now your tag declares the attribute partizione as being of type ContenitorePartizioneBean which is probably the cause of the problem - you are passing it a String.

Connection Pooling and JSP Custom Tag Library - is code (inside) the best way/correc?

Hi, can anyone advise as to whether my tag library code (based
on Apache Jakarta Project) will actually achieve connection
pooling functionality across my entire JSP based application? I
am slightly concerned that my OracleConnectionCacheImpl object
may exist multiple times, hence rendering my conection pooling
attempt useless.

Can you please help me the reason why this problem is happening and how to fix this ?
This problem doexn't happen consistently. This occurs once in a while.
I tried to increase Login delay Seconds parameter in the Connection Pool to 15 sec. It didn't help me much.
Thanks for your help !!!

There are a number possible reasons for the error "runtime failure in custom tag
'process'" for WLCS 3.11 and 3.2. You might check the following:
1) Make sure that WebLogic Server 5.10 SP6 is installed correctly and that
weblogic510sp6.jar and weblogic510sp6boot.jar are at the fronts of
weblogic_classpath and java_classpath, respectively.
2) Check to see if weblogic-tags-510.jar from WebLogic Server 5.10 SP6 is copied
to %weblogic_home%\lib\weblogic-tags-510.jar.
3) The WLPS database is corrupted for reason or another. Rerun the appropriate
database script at \weblogiccommerce\db\cloudscape\create-all-cloudscape.bat or
\weblogiccommerce\db\oracle\create-all-oracle.sql.

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,
Frank

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!

Custom tag attribute case insensitive??

We ran in to an interesting "feature" of custom tags: The attributes in the
          tags seem to be case insensitive.
          For example, if you play with the "tagext/quote" example provided with the
          WebLogic server installation, you can change the line in showcode.jsp to be
          like:
          <quote:code quoteColor="blue" COMMENTCOLOR="purple"
          defaultFont="face=Helvetica color=gray">
          and the generated java servlet code will still call the "setCommentColor()"
          method in the CodeTag class. Almost like it searches for a matching
          "attribute" in the .tld file and uses it. If you put multiple entries in
          the .tld file for different cases, it still picks the first one it finds and
          ignores the case differences.
          The J2EE/JSP spec indicates that custom tags are case sensitive, I assumed
          that is supposed to include their attributes.
          It bit us because we want to have attributes which differ by case only
          (don't ask).

I had the same problem in a design a couple of months ago and could not get around it so I switched the functionality into code and out of the tag lib.
I take it you are trying to do something like this?
<%
String value="hiworld";
%>
<mytaglib:saysomething value="<%=value%>"/>

Custom tag attribute calculated by scriptlet expression

Hi,
          If I set the rtexprvalue subelement of the attribute element in my tld to
          "true", should I be able to dynamically determine the value of my custom tag
          attribute using a scriptlet expression?
          When I include the custom tag reference:
          <prod:getCategory id="category"
          categoryID="<%=request.getParameter("catID")%>" scope="page"/>
          it actually gets written to the html as:
          <prod:getCategory id="category" categoryID="2133" scope="page"/>
          and is not recognized as a jsp tag.
          I am using weblogic 6.0 sp1.
          Thanks in advance!
