Custom Tag - Unable to Load Library

I'm working on a project that needs to access custom tags. .
We are using CFMX Version 6,1,0,63958 Edition Enterprise Operating
system Windows 2003 OS version 5.2
The Web application relies on 4 custom tags written in C++. I
can get the first tag to work. The other tags work on my developer
edition (CFMX 7), but I cannot
get them to work on Version 6.1. I get the error "Unable to
Load Library". These other custom tags each call an external DLL
from within side them and I
believe that this is what's causing the problem. I've tried
researching this problem for months, checking the forums, Google,
etc. but nothing has worked.
I have a deadline coming up soon, so any help or advice to
get me in the right direction
to solve this problem would be greatly appreciated. I don't
know what to do and I need a solution!
Thanks

That worked. It was looking for the dll in CFusionMX\Lib
instead of in the CFX\custom tags folder.

Custom tag - unable to find setter method error

I see this compileException on IAS but not on BEA app server and iWS.
JSPProvider.processJSPFile(): jsp=searchContent.jsp, org.apache.jasper.compiler.CompileException
Unable to find setter method for attribute: input
The reason is because the custom tag has a setInput() that takes a String parameter while the getInput() returns an InputStream.
Should both get and set methods have the same type of parameters or is this a due to a bug in the app server ?

I was only going off info from the original post. The error specifically states "Unable to find setter method for attribute: input" with a lower case i for the input attribute. You also specifcally stated "The reason is because the custom tag has a setInput()" with a capital I for the setInput method. This would most definitely cause the error you were receiving. That is unless you corrected this between your original post and your followup testing.

c:import tag unable to load xml file

I'm using weblogic 8.1 sp5. This is how my jsp looks like:
 <%@ taglib uri="/WEB-INF/x" prefix="x" %>
 <%@ taglib uri="/WEB-INF/c" prefix="c" %>
 <c:import url="/WEB-INF/ADVLSOG6Request.xml" var="file" />
 I get an error message in the console window that says, "included resources or file "/lwise/WEB-INF/ADVLSOG6Request.xml" not found from requested resources /lwise/pages/ADVRequest.jsp"
 The xml file is under WEB-INF directory. I've even tried putting this file in the same directory as jsp i.e. /lwise/pages/ and changes the c:import tag to <c:import url="ADVLSOG6Request.xml" var="file" /> so that it can locate it but to no avail. I've tried deploying both as war module and exploded directory but still gives me the same error. I'm using JBuilder Enterprise 12 as my IDE - jsp 1.2. Any idea how can I load this class using this tag? or why it cannot see it? Thanks.

The paper says
“Unable to set attribute” error message will be displayed. Run the CameraValidator.exe utility with the “/ATTRIBUTES” flag to detect which attributes are generating errors and contact your camera vendor for a new and updated version of the camera firmware.
I've run the CameraValidator.exe but it couldn't find the camera or the attributes.
Also check the firmware version

Load Library Failures

I just upgraded to a new box - was previously on IIS6,
Windows 2000 Server and CF7 - None of my CFX tags are loading -
CFX_ZIP, Image, etc. I get the Unable to Load Library exception.
Unfortunately - we rolled to a production server and our testing
missed these - it's amazing how much things are used when you skip
right through them!

By default Windows (and hence Java) will look for your DLL in several places - one being the working directory, I think it also looks under the Java installation directory somewhere (that's probably where your C:\Program Files\ entry is coming from), one being the OS directory (C:\WINDOWS\, or C:\WINNT\ or something), and so on.
I think you can set the LIBPATH as well? Or was that Win95/97/Me? I forget.
Anyway, this is all to do with how Windows works - it always looks in all these places before admitting that it doesn't know where a DLL is.
The exception is if you specify the full path to the DLL (which in Java I think you can do in the loadLibrary call), when I think it looks only in that place. But that's not recommended as you might want to change your mind later without recompiling the code.
Anyway, normally it will look in all these places, but it will also look in the place you specify with the -D syntax above, and (importantly) it will look there first. So if you set that and place your DLLs there, you won't get the error.

Custom tag as performance hits.

 Hi All,
 I want to know if there is a correlation between the number of custom tags used in
 a JSP page and the page's performance.
 Is there a guideline/study which indicates (or otherwise) that increasing the number
 of custom tags decreases the loading (rendering) time of the JSP page. I understand
 that more tags mean more jsp-compilation time but I am interested in runtime performance.
 Thanks,
 Anu

 Each additional tag adds some runtime overhead. The overhead is primarily
 determined by the quality of the tag implementation. I'd rather have 1000
 well written tags than 1 poorly written one ;-) ... e.g. if you are doing
 JDBC calls from a tag, then you will probably get into trouble in a hurry.

Unabale to load library

I'm moving from cf5 to cfmx7. I moved over a spell check that

the error "Unable to load library ". Any ideas about what I need to

OAAM 11g R2: Unable to load java class for custom configurable action

Need to configure a Configurable Action to get triggered for a particular action at a given checkpoint.
Steps Followed:
1. Created a java class implementing com.bharosa.vcrypt.tracker.dynamicactions.intf.DynamicAction, getParameters() and execute() methods were implemented in that java class.
2. Added necessary jars from $ORACLE_IDM_HOME\oaam\cli\lib to the build classpath.
3. Compiled and created a jar with it.
4. Extracted the oracle.oaam.extensions.war file into a working folder.
5. Added the Custom Jar created in step 3 into <working folder>/WEB-INF/lib/
6. Changed the following in MANIFEST.MF in <working folder>/META-INF/:
Specification-Version:11.1.2.0.1
Implementation-Version:11.1.2.0.1
7. Rejar-ed the oracle.oaam.extensions.war from the working folder using following command:
jar -cvfm oracle.oaam.extensions.war <working folder>\META-INF\MANIFEST.MF -C <working folder>/ .
8. Stopped the oaam_admin_server1, oaam_offline_server1 and oaam_server_server1.
9. Deleted the oracle.oaam.extensions deployment from the weblogic.
10. Deployed the newly created oracle.oaam.extensions as a shared library for oaam_admin_server1 and oaam_server_server1.
11. Started all managed servers.
But when I tried to create an action template with the java class I just created, it was throwing following error

This thread is a bit stale but I thought it might help to clarify one point about custom jar files on UCCX.
To properly load a custom jar:
Upload it into the classpath directory in the document repository.
Select it under System | Custom Classes Configuration
Finally you need to restart the CCX Engine and the CCX Administration services. If you have HA you need to restart them on both servers.
Other notes:
When referencing your class in the CCX Editor, use the fully qualified name of the class. Lots of other classes use things like Element or Document so you need to be explicit. The editor only knows about the 20 native classes by their object names. If you create a Document object in the editor you are really creating a com.cisco.doc.Document object. If you loaded jdom.jar and you wanted a jdom document then you need to create an object of type org.jdom.Document.
When compiling your custom jar files, be sure to compile for the version of Java that the CCX Engine runs. In general UCCX 7.X and older use Java 1.4. UCCX 8.X and higher use Java 1.6. Several of the core Java classes had significant changes between 1.4 and 1.6. If you ran your code on UCCX 7 or earlier and now it fails in UCCX 8.X or higher, recomplile for Java 1.6 and you classes will likely work again.
Finally, check for security violations in UCCX 8.X or higher. Cisco has restricted some of the things you can do. These URL's have more information:

I have created the tld file and put it in the directly WEB-INF FOLDER.I have written a jsp as well which uses this tag and the uri in the jsp mathces the uri in the tld file. Then it gives me the error message that unable to find the tld file.
then i made entry in the web.xml as well but now it is giving me an error:
JSPG0227E: Exception caught while translating /UseCustom.jsp: /UseCustom.jsp(19,1) --> JSPG0009E: Unable to load tag handler class com.hcl.taghandlers

By the thanks to all those who devoted some time to think over it.

Custom tag library called multiple times

Hi ppl ,
I have a custom tag library which i use to populate some menu components. When i do call my custom tag library though , it is called multiple times, use case is as follows.
I have menu tabs and menu bars which thanks to Mr.Brenden is working splendidly as so:-
<af:menuTabs>
<af:forEach var="menuTab" items="#{bindings.menu.vwUserMenuTabRenderer.rangeSet}">
<af:commandMenuItem text="#{menuTab.MenuLabel}"
shortDesc="#{menuTab.MenuHint}"
rendered="true"
immediate="true"
selected="#{sessionScope.selectedMenuId == menuTab.MenuId }"
onclick="fnSetSelectedValue('#{menuTab.MenuId}')" >
</af:commandMenuItem>
</af:forEach>
</af:menuTabs>
<af:menuBar>
<af:forEach var="menuBar" items="#{bindings.menu.vwUserMenuBarRenderer.rangeSet}">
<af:commandMenuItem onclick="return clickreturnvalue()"
onmouseover="dropdownmenu(this, event,#{menuBar.MenuId}, '150px')"
onmouseout="delayhidemenu()"
text="#{menuBar.MenuLabel}"
action="#{menuBar.MenuUri}"
rendered="#{menuBar.ParentId == sessionScope.selectedMenuId}"
immediate="true" />
</af:forEach>
</af:menuBar>
</afc:cache>
now all of this code is within a subview , and just directly below the subview tag , i have the call to my custom tag library:-
<myCustomTagLib:menuCascade />
only issue now is that assuming i have in all 7 menu bar components, the doStartTag is called 7 times. the relevant code within my custom tag class is as follows :-
public int doStartTag() throws JspException {
return (EVAL_BODY_INCLUDE);
public int doEndTag() throws JspException {
try {
declareVariables();
return EVAL_PAGE;
}catch (Exception ioe) {
throw new JspException(ioe.getMessage());
and within my declareVariables method i do an out of the jscript ( out.print(jscript.toString()); ) which is a simple string generated based on certain conditions...
now it seems to be working fine on the front end , but when i view the source of the page, i notice that the declaration is called multiple times, and this happens because the doStartTag method is called multiple times, i haven't even nested the call to the custom tag within the menu components , any clue as to whats going wrong ?
Cheers

Hi,
if you add the following print statement
System.out.println("rendering "+FacesContext.getCurrentInstance().getViewRoot().getViewId());
Then the output in my case is
07/04/24 08:14:04 rendering /BrowsePage.jsp
07/04/24 08:14:05 rendering /otn_logo_small.gif
The image comes from the file system, which means it is rendered by the JSF lifecycle. If you reference the image with a URL then the lifecycle doesn't render the image but only refrences it.
To avoid your prepare render code to be executed multiple times, just check for jsp and jspx file extensions, which will guarantee that your code only executes for JSF pages, not for loaded files.
The reason why this happens is because the JSF filter is set to /faces , which means all files that are loaded through that path

Custom Tag Library - error in IWS

My environment: Solaris 2.7, IWS4.1 SP3.
I currently try to run the Custom Tag Library example from IWS itself in
server_root/plugins/samples/servlets/taglibs. I follow the instructions to
config the IWS but fail to run the example. I turn on JSP debugging and
find the following error messages:

I have tried another much simple Custome Tag Library example that only contain a simple tag that do output to page, but still getting the same error.

I had the same issue with WAS 6.1.0.2. I do not have a solution, but a workaround. I hope the workaround I have works for you too.
In my case, I have the TLD files deployed in a jar. So, the JSP 2.0 container is supposed to read those TLD files from the jar file. Since that was not happening, I extracted the TLD file from the jar file and placed it under my web project's WEB-INF folder.
I restarted my server and after that it worked.
Look at the IBM site to see if they have come up with a patch for WAS 6.0.
Hope this helps.

The server was unable to load the SSL provider library needed to log in

Hello All,
When I am trying to login to my default SQL 2008R2 SP2 instance in windows 2003 server via ssms, I am getting the below error
A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.) (.Net SqlClient Data Provider)
When I looked into the error log and i could see lot of these messages.
The server was unable to load the SSL provider library needed to log in; the connection has been closed. SSL is used to encrypt either the login sequence or all communications, depending on how the administrator has configured the server. See Books
Online for information on this error message: 14 Not enough storage is available to complete this operation.
Force protocol encryption is set to off.
I am not sure what is the underlying problem. server's total RAM is 4 Gb and max_server_memory is set to 2 GB. CPU utilization is very normal at the time of issue.
I restarted the SQL service and i am able to connect to the instance, but the issue is repeating and i need to find a permanent fix.
Thanks

I could also see the below in error log some time before i get the above alert
Error: 701, Severity: 17, State: 123.
There is insufficient system memory in resource pool 'internal' to run this query
then after sometime flurry of alerts

Teamspeak3-server: unable to load database plugin library

After applying the latest package version, I get: "unable to load database plugin library "libts3db_mariadb.so".
It used to run perfectly fine before. libts3db_mariadb.so is present at /usr/lib/
I am stuck and don't know what to check next. Please advise.

It seems the same conclusion is discussed on the AUR already; did you read that?
