Exception in Tag Classes

          Hi,
          I am trying to use custom tag libraries with WebLogic. Whenever I use some custom tag in some JSP page, an exception occurs in the tag class code. Following is a portion of stack trace.
          Thu Sep 21 12:58:04 GMT+08:00 2000:<E> <WebAppServletContext-ebanking> Root cause of ServletException
          javax.servlet.ServletException: runtime failure in custom tag 'text'
               at jsp_servlet._webpages._login._jspService(_login.java,
          Compiled Code)

               at
          weblogic.servlet.internal.ServletStubImpl.invokeServlet
          (ServletStubImpl.java:124)
          For some tags the exception is ClassCastException.
          Is there any special configuration reqired for using tag libraries? Please help.
          Thanks

You need to look at the class cast issues that have been discussed in the
          weblogic servlet newsgroup. Chances are that you are storing a value in the
          session or request object and getting it back out in the custom tag, right?

          The class does contain the setter, so we don't know why the message pops
          up. After rebooting the server, the page works properly (!) Does anyone
          know how to get rid of it ? We're running out of ideas, and rebooting
          the server every 2-3 days is not acceptable.
          The configuration consists of BEA WebLogic 5.1.0 SP8 + JDK 1.2.2_07 +
          HPUX 11.0.
          Any help is greatly appreciated.

so doesn you bean have a
          void setLimit(String) {}
          String getLimit() {}
          or does it have mismatched getter and setter?
          like
          setLimit(String) {}
          int getLimit() {}
          take a look at :

Custom component/tag class: ---which setters/getters do what?

Hi
I'm trying to create a custom component, but, there is a major concept that I do not understand...
---What are the setters/getters in the "component" class used for?...
---What are the setters/getters in the "tag" class used for?
Another way of asking is...
---Which setters/getters are used simply to keep track of attribute name/id/key?
---Which setters and getters refer to the actual objects that the attribute names point to?
The reason for my confusion is that nearly all "custom component" examples I've seen thus far, utilize attributes that point to "String" objects... (i.e., as opposed to ArrayList, HashMap, etc)...
This makes it difficult for me to distinguish whether the String values in the getters/setters are referring to the String name/"id" of the attribute...or, the String "value" of the attribute...
I have not been able to verify how I should code the getter/setters (and type casts) for other kinds of objects like ArrayLists, HashMaps, etc
For example, a typical logic mechanism Ive seen in the custom "tag" examples is as follows...
in a "tag" class...
        if( tabledata != null )
            if (isValueReference (tabledata))
                FacesContext context = FacesContext.getCurrentInstance ();
                Application app = context.getApplication ();
                ValueBinding vb = app.createValueBinding (tabledata);
                component.setValueBinding ("tabledata", vb);
            else
                component.getAttributes ().put ("tabledata", tabledata);
in the "component" class...
    public void setTabledata (List tabledata)
        this.tabledata = tabledata;
    public List getTabledata ()
        if(null != tabledata)
            return tabledata;
        ValueBinding _vb = getValueBinding ("tabledata");
        if(_vb != null)
            return (List)_vb.getValue (getFacesContext ());
        else
            return null;
    }...considering the above code,
---when/where should the "tabledata" variable be referring the "name/id" of the attribute?...
---when/where should the "tabledata" variable be referring to the "value" of the attribute?...
...as, I need to change the type casting to adjust to what it should be...
***NOTE: This is one error that I'm getting, and I believe it is because I do not understand how getter/setter is used in "component" and "tag" classe, i.e., :
"org.apache.jasper.JasperException: jsp.error.beans.property.conversion
     org.apache.jasper.runtime.JspRuntimeLibrary.getValueFromPropertyEditorManager(JspRuntimeLibrary.java:885)"...
Thanks for any help on this!

The "tabledata" variable always refers the local value of the attribute.
When using a value binding to some backing bean,
the local value is null and the model value is owned by the bean.
You don't need any casting in the tag class nor the component class.
The setters/getters in the component class specify the type of the attributes.
Conversion from/to String to/from the type is done automatically if possible.
When the automatic conversion is impossible, you should specify f:converter
for the attribute.

How to resolve #{row} of af:table in custom tag class?

Hi all,
My customer creates custom converter tag with some attributes. When they use it outside af:table, it works as expected.
However when they use it in af:table and set "#{row.value}" into the tag's attribute, it doesn't work because it can't resolve #{row} EL expression.
The method they wrote is like below.
private Object getExpressionValue(ValueExpression expression) {
if (expression == null) {
return null;
final ELContext elContext =
FacesContext.getCurrentInstance().getELContext();
return expression.getValue(elContext);
Does anyone know the way to do resolve #{row} expresison in custom tag class?
If you share sample codes, it will be much appreciated.
Regards,
Atsushi

Hi,
the row variable is a temporary variables, which means that #{row} may work when the table renders but not when users edit fields in a table and then submit the change. You don't really mention what doesn't work for your customer (and wouldn't it be better your customer could post here on OTN to avoid you becoming a dispatcher?) . An expression #{row.value} for example doesn't exist unless your customer uses a POJO model that has a property "value" in which case the entity has a setValue/getValue.

Custom taglib access the variable of jsp in the tag class

Hi guys:
I have a question about taglib.the scenario below
there are a set of tag,they all need to access a variable that declare in the jsp.yes ,I can use the approach like this,
first I declare a variable
<%!String variable="test";%>
then pass the value
<myTag:hello att="<%=variable%>"/>,but I think that's stupid,because all tags access the same variable.why not get the variable in tag class?
for example
public int doStartTag() {
String variable=;//get the variable at here
I mean,I want to get the variable's value in my tag class directly without passing parameter in the jsp via attribute of tag ?
can I do like this?if yes,how can I?
thanks advance!

Hi,
Review pageContext, TagSupport from the JSP and Tag Extensions API. You can put the variable into any of the four scopes and retrieve it using the pageContext object.

Hi,
you may want to try the J2EE forum here on OTN in case you don't get a sufficient answer to the problem.

Where to place tld,tag class files to create a small custom tag

hi ,
please any one help me to create a small custom plugin wothout using JSTL

Your TLD will reside in the WEB-INF/ directory, whereas your tag class will be put into WEB-INF/classes/ directory, depending on your package it'll live in a directory somewhere under that. Of course, you could also put the TLD and tag class into a JAR file and place that under WEB-INF/lib/

How to recover from an exception on a class loaded with a classloader?

I have created a classloader for the purpose of dynamically loading "modules" . The whole application is multithreaded and the separate modules may also run as separate threads. The problem that I am facing is that if one of the modules crashes (does not handle an exception), then the class loader object which loaded the required classes and started the module's thread, cannot be accessed. The thread which attempts to access this class loader freezes. Is there any way to recover from this situation?
Thanks in advance

Ok, let me provide a bit more information. Each "module" is handled by specific class (let's call it ModuleDescriptor), which subclasses the URLClassLoader class. The ModuleDescriptor class is responsible for describing each module, maintain module state information (loaded, unloaded, started, stopped, etc) and also executing some method calls on a specific object of the module, which in essence acts as a means to start or stop the module. Each module is a separate thread and is packaged in a JAR file, which is first downloaded locally. If one of these module threads crashes, then I cannot even call a method of the ModuleDescriptor to perform the necessary unloading bit. Basically, when I can the method that thread of execution halts without an exception or an error or anything. The rest of the application continues working properly (other threads). I find this situation bizarre, because the ModuleDescriptor object and the actual module with the thread that crashed execute on separate threads. If there is any more specific information that I have to provide, please let me know.

Missing tag class on 10.1.3 but not in JDev embedded oc4j

I have a JSP 2.0 application created with a few custom tag files in web-inf/tags. The app runs fine within Jdeveloper's embedded oc4j (10.1.3). After deploying the EAR of this application to a 10.1.3 app server, everything works fine except in the way the server compiles the tag files. It puts them in the wrong folder!
It puts the _tags directory in this folder:
C:\Oracle\product\10.1.3\OracleAS_1\j2ee\FastConnect\application-deployments\FastConnect\FastConnect\persistence\_tagfiles\_nullweb_2d_inf
When I manually copy the tags up one directory, the app works and I do not get a missing class error. What is telling my app server to put the generated tag file classes in this nullweb_2d_inf folder?

OC4J 10.1.3 does support JSP 2.0, as well as custom tag libraries (including JSTL 1.1).
There are two approaches to configuring a custom tag library for use in JSPs served by OC4J:
1) Package the JSTL or custom tag library with your application:
i. include the necessary JAR file in your web app's /WEB-INF/lib folder
ii. include the relevant Tag Library Descriptor (TLD) file(s) in your web app's /WEB-INF folder
iii. for each TLD, add a <tag-lib> element to web.xml referencing the TLD file's location and taglib URI
2) Place the JSTL or custom tag library in an Application Server instance-level directory ($ORACLE_HOME/j2ee/home/jsp/lib/taglib) to make them available to multiple applications (in all OC4Js installed in the Oracle Home)
For example, if you'd like to use the JSTL 1.1 Core and Internationalization Tag Libraries, do one of the following:
1) Package the JSTL or custom tag library with your application:
i. Obtain an implementation of JSTL (e.g. Jakarta Taglibs) and include the standard.jar and jstl.jar files in your web module's /WEB-INF/lib directory
ii. From the JSTL implementation you're using, also copy the c.tld and fmt.tld Tag Library Descriptors to your web module's /WEB-INF/lib directory
iii. Add the following elements to your web module's web.xml file:
<jsp-config>
<taglib>
<taglib-uri>http://java.sun.com/jsp/jstl/core</taglib-uri>
<taglib-location>/WEB-INF/c.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>http://java.sun.com/jsp/jstl/fmt</taglib-uri>
<taglib-location>/WEB-INF/fmt.tld</taglib-location>
</taglib>
</jsp-config>
OR
2) Copy the standard.jar and jstl.jar libraries from the JSTL implementation you're using to $ORACLE_HOME/j2ee/home/jsp/lib/taglib

Error when testing a webservice - Exception raised in class CL_SOAP_REGIST

Hi folks,
I've got an issue concerning the AS ABAP SOAP Runtime. The system is an ERP 6.0 with SP13.
At first I create a Web Service by using the context menue of an existing rfc-enabled function module. Afterwards the service is visible in SICF. If I try to test the service in WSADMIN by using the test-button I only get an exception in the opening internet browser:

I found out that the exception is raised since CL_SRT_WSDL_GEN_FACTORY=>GET_WSDL_GENERATOR doesn't return an instance of the class referring to the interface IF_SRT_WSDL_GEN.
If I test that method in SE24 using the name of the service definition in SE80 for the parameter WSD, the value '1' fpr the parameters TYPE and STYLE, an instance of the class CL_SRT_WSDL11_GEN is rendered.
Could you give any hints how I could debug that issue to verify the import parameters when the static method CL_SRT_WSDL_GEN_FACTORY=>GET_WSDL_GENERATOR is called in the body of the browser call ?
Or any other hints?
Thank you very much and best regards
Stefan

The issue was due to missing authorizations of the RFC-user (type 'Communication') calling the webservice. The RFC-user itsself has been assigned before to the webservice in the http-service tree (transaction SICF). RFC-User needs (at least) the role SAP_BC_WEBSERVICE.

Calling a PP03 BDC from abap webdynpro throws an exception from the class

Hi Experts,
I am calling a BDC FM for PP03 TCPDE form abap webdynpro.
When i run the standalone FM, it works fine and When called from Webdynpro its giving a dump saying an exception is raised in the class CL_GUI_SPLITTER_CONTAINER.
Can you please let me know how to resolve the issue? Your siggestions will be of great help to me.
Thanks,
Shilpa

Hi,
The FM might be calling a dialog or bringing a GUI screen up. This would cause the Webdynpro session to disconnect abruptly.
Any conversion exit, GUI screen,dialog popup, transaction handling..etc would cause the webdynpro to disconnect. So you cannot use all FM's as it is.

Null pointer exception with inner class

Hi everyone,
I've written an applet that is an animation of a wheel turning. The animation is drawn on a customised JPanel which is an inner class called animateArea. The main class is called Rotary. It runs fine when I run it from JBuilder in the Applet Viewer. However when I try to open the html in internet explorer it gives me null pointer exceptions like the following:
java.lang.NullPointerException

Do inner classes have to be compiled seperately or anything?

I think that I am using the Java plugin ( Its a computer in college so I'm not certain but I just tried running an applet from the Swing tutorial and it worked)
Its an image of a rotating wheel and in each sector of the wheel is the name of a person - when you click on the sector it goes red and the email window should come up (that doesn't work yet though). The stop and play buttons stop or start the animation. It is started by default.
This is the code for the applet:
