JSP Custom tag issues.
Hi all,
When my JAVA_HOME env variable is pointing to C:\jdk1.3, the JSP below which contains some custom tags fails to compile in Weblogic 5.1. However, when i change my JAVA_HOME env variable to C:\weblogic\jre1_2\jre, the same JSP compiles and deploys with no problems. I was of the opinion that the jre in jdk 1.3 is the same as jre1_2 which is bundled with weblogic 5.1. Does anyone know of any differences btw the Jre's or why the JSP below cannot be compiled when i use JDK1.3. Thanks for the help.

UUh, interesting.
Try to use the last Service Pack for 5.1 - i think it is sp9.
Hope it'll work. I've had some problems with XML parsing but they resolved when I installed the last SP...

Please resolve my issue..I had the same problem. In your .tld change tagclass to tag-class and bodycontent to body-content and that should do the trick. The names slightly changed for JSP spec 1.2.

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.

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.

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
SanthoshHi 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

Data Streaming in JSP custom tag
We have a JSP custom tag which uses a StringBuffer object to store the HTML content. In the doEndTag method, we use the JSPWriter's print method to send the buffer's content to the browser.
Now, there are cases when the HTML content becomes very large,in the order of 1 - 10MB. In such cases, is there a way we can start streaming the data from the custom tag as the buffer is being built, rather than waiting for the entire buffer to be written out in the doEndTag.Yeah, just call the JSPWriter's print method instead of using the StringBuffer, or write your own subclass of StringBuffer (or StringBuilder if Java 5+) which will do this for you automatically when the size is at a certain point, and clear it out)

Can I write Design-time for JSP custom tag(not JSF components)
I have some old JSP custom tags(not JSF components), and I want to use them in the IDE through the toolbox.
Now I have already written the BeanInfos for these tags, and they can be drag from the toolbox; but it will throw a Exception when render the tags, and the properties in the Property Editor are not which I describe in the BeanInfos.
How can I write Design-time for these tags? or whether it is possible to write the Design-time for these tags?

Aggressive Caching of JSP Custom Tags?
I've just developed my first JSP Custom Tag. I compiled my class and it
worked fine. But subsequent changes to the class source and recompiles
don't affect the JSP output; evidently, these are aggressively cached, so
much so that 12 hours later it still won't change (I was hoping it would be
a 10 minute timeout or something like that.)
Is this the problem? If so, is there a weblogic.properties setting to tell
WL to check for modifications to the class file every so often?
David
Lets say i want to have some user defined exception messages.There
i will say in tag support or body tag support i will use JSPException
and throw my customised exception.
Can any one tell me any practical example.
If someone really have used it somewhere.
thanks

How to call a method repeatedly with JSP custom tag?
This senerio is very similar to the usage of StringBuffer.
I have a problem which can be solved easily with scriptlets:
<% NameValuePair nvp = new NameValuePair(request.getQueryString()); %>
<a href="foo.html?<%=nvp.add(name1", "value1").add("name2", "value2").toString();%">">Foo</a>
<a href="bar.html?<%=new NameValuePair(request.getQueryString()).add("x", 1).add("y", 2).toString()%>">Bar</a>
But I cannot use scriplets because it's turned off. I can only use jsp custom tag / jstl. How would I implement this functionality with a custom tag? How would the JSP code look like? Our container supports JSP 2.0.
Thanks.</a>hi,
you can do within 2 step-
1) use <%@page import="your_java_class"%>
2)use scriptlet code <%...%> and write coding in this tag.
means create instance of your java class .
<% your_java_class obj1=new your_java_class();
obj1.method_of_your_java_class();
%>or
3) you can make javabean to use method of java class.[Best option]
Thanx

>Hi.
I had similar problems with appc.
Try to remove the line "<%@ tag language="java" pageEncoding="UTF-8"%>" or at least the pageEncoding attribute from the *.tag files.
In my case, I had no idea why the compiler complained about encoding. No UTF-8 specific characters were used and both, *.jsp and *.tag set the same encoding by directive.
If you get rid of the "The encoding specified on the page cannot be different than detected encoding for the file.", you will also get rid of the "The tag handler class was not found" and the resulting errors. -
I'm using custom tags in my app (JSP 1.2). My tld is located in WEB-INF/tlds (not packaged in a JAR), meaning that the uri in the tld file should be picked up by JSP 1.2's autodiscovery. This works fine in actual deployment, but Nitrox claims that:
"The tag library uri "mytaglib" cannot be mapped to an existing tld file. "
when I attempt to reference it as follows from within my jsps:
<%@ taglib uri="mytaglib" prefix="m" %>
Do you know if this is a bug, or have any suggestions as to why the tld uri isn't being picked up by Nitrox?
Thanks,
JohnThis is a known (kind of) issue. There are 2 easy workarounds:
1- Specify the path to the tld file in the uri attribute. For example:
<%@ taglib uri="/WEB-INF/mytaglib.tld" prefix="m" %>
2- Map the tld file in web.xml. For example:
<taglib>
<taglib-uri>mytaglib</taglib-uri>
<taglib-location>/WEB-INF/mytaglib.tld</taglib-location>
</taglib>

Initialization of parameter values in JSP Custom Tag Handlers
Hi - I have a tag handler for a custom tag that has no body, but accepts
some parameters.
If the parameters are optional and are passed with the tag in the source jsp
page, then all is fine.
However, for subsequent uses of the same tag in the same page if the
optional parameters are omitted, the previous values remain in the instance
of the tag handler class, as the attributes for the tag handler are declared
as instance variables (with corresponding getters and setters) as per the
tag handler specs.
eg:
<abc:sometag attrib1="a" attrib2="b"/>
if attrib1 and attrib2 are optional, then a subsequent use of this tag, eg:
<abc:sometag/>
attrib1 and attrib2 still have their previously assigned values of "a" and
"b".
Is there a method I can call to get the actual values of the attributes that
were passed on a particular call to the tag handler, or is there a way to
initialize the attributes before the tag handler processing method, eg
doBeforeBody(), doAfterBody(), is called?
Thanks,
Kevin Hooke
Yeah, just call the JSPWriter's print method instead of using the StringBuffer, or write your own subclass of StringBuffer (or StringBuilder if Java 5+) which will do this for you automatically when the size is at a certain point, and clear it out)

Design view for jsp custom tags.
when we drag-and-drop custom tag control in the source of jsp page, when we switch to the design view of jsp we should be able to view controls as desired.
Observation: 1) Eclipse 3.2 doesn't have design view for jsp pages.
2) which software uses the design view. we need to extend eclipse core framework and we do not find any technical approach document to proceed further on this.
3) RAD 6.0 we can see a JSP in design view.
I'm searching for any technical approach document to create plugin that can intercept the custom tags and provide a design view.
Will any one suggest the plugin for that.Jeff,
I have checked with engineering and found that JSP Design View support on
Linux is a planned feature for the next release. I don't think we will have
this feature as part of a Service Pack for 8.1

Unfortunately, the JSP design view is currently not supported on Linux.
Workshop does allow to do remote development where the IDE is running
on a
Windows machine and connects to a server running on Linux/Solaris.

Does anybody else who is running the Linux version of Workshop 8.1have

with
no tabs at the bottom to switch to/from the Design View. When I bootover

Is it something I have set in Preferences somewhere that disablesthe

Using gateway'd URLs in JSP custom tag attributes
Hello,
I am running Plumtree G6 using a gateway prefix to gateway Javascript from a remote server. I have recently discovered, thanks to people's help on the forum here, that in certain cases, you need to wrap a URL in a pt:url tag in order for Plumtree to recognize it as a URL that has to be gateway'd (i.e. a URL inside of a Javascript function).
However, I have a custom tag that contains a contextPath attribute. This custom tag then includes other XML files that get included in the final page that is displayed. I am passing this value as my contextPath:
<mytag:body sessionName="mysession" campusName="SampleCampus" contextPath="<pt:url pt:href='http://localhost:7021/application/scripts' xmlns:pt='http://www.plumtree.com/xmlschemas/ptui/'/>"/>
However, in the resulting content that is created from this custom tag, the contextPath value is still set to <pt:url pt:href=......./>, and not the actual gateway'd URL. I would have thought that Plumtree would have recognized and gateway'd this URL before it got substituted in the custom tag.
Does anyone have any thoughts on how to get around a problem like this? One thought I had was to get ahold of the gateway URL value and pass that value directly in my contextPath attribute. Is it possible to get that gateway value, or is there a better solution here?
Thanks again for any help you can provide.Chris,
I added your code, changed the portlet's web service to send a login token for this portlet, and was then getting some ClassNotFoundExceptions related to Axis classes. So, I went and added all of the jar files from the devkit's lib directory (i.e. plumtree\ptedk\5.3\devkit\WEB-INF\lib), recompiled, and those errors went away. But, now I see the following error:

JSP Custom tag not working correctly for multiple users
I am doing some support work for an existing web system. When doing single user access (a custom tag is called within the JSP); the output of the Custom tag is fine. However, during multiple user access to the JSP, as I could see on the log files, 2 users access the custom tag at exactly the same time- the output of one of the users was incorrect. The custom tag btw, uses TreeMap, Stringbuffer and does not have a body, only attributes passed to it. It takes an input file and a Hashmap as input attributes and it sets a string in the page context which is later being used in the JSP. No error is logged, its just that the string produced(placed in the page context) is incorrect. This only happens when this tag is called at same time(when multiple users accessing the page) Has anyone encountered this problem? Is there a known pooling/thread problem with custom tags?
in a servlet/jsp (a jsp is compiled into a servlet),
the class atrributes are shared. only the
variables declared in the doservice (doGet or doPost)
method are threadsafe.
post your jsp plzhere's the snippet of the jsp code:
<%@ page language="java"
errorPage="Error.jsp"
autoFlush="false"
buffer="128kb"
import="java.text.*,
java.math.BigDecimal,
java.rmi.RemoteException,
java.util.*,
java.io.*,
%>
<%@ include file="Secure.jsp" %>
// a set of request.getParameter are being called here
HashMap myMap = new HashMap();
myMap.put(xmlDPhoneNumber, dPhoneNumber);
myMap.put(xmlDPhoneType, "D");
myMap.put(xmlDPhoneExt, dExtension);
myMap.put(xmlDPhoneDigits, dPhoneDigits);
// other myMap putting of key values are called here
%>
<test:applyCustomerSearchValues id="resultXml" xmlTemplate="/xml/message/CustomerUpdateRequest.xml"
xmlMap="<%= myMap %>" />
<test:transformXMLString id="customerUpdateRequest"
xmlString="<%= resultXml.toString() %>"
xslFileName="/xsl/message/CustomerCreateRequest.xsl"
paramMap="<%= PMap %>"/>
now here's the thing: the xml produced by test:applyCustomerSearchValues is resultXml which is used in test:transformXMLString. I got no problem with the output of test:transformXMLString. I am sure that a phone number is being passed into the former as part of the HashMap key-value. However when test:applyCustomerSearchValues is called when 2 users access the jsp, it seems like the the first xml produced does not have the phone number in it - but the other has it. The xml is OK for both users, its just that the values of the HashMap do not seem to be passed correctly into the xml produced.
--- here's the snippet of the log, the first httpWorkerThread-80-6 does not have the phone number, however the second one-httpWorkerThread-80-7 has the phone number. The first one should also have a phone number as in the start of the log, the number was listed, but as the system called the test:applyCustomerSearchValues tag, the number was not included. There are different phone numbers for the 2 users. The odd thing here is, the userID which is the 'LastUpdatedBy' element has been set correctly. The userID is being fetched from a session attribute while the phone number is fetched from a request parameter, both are being placed in the HashMap attribute passed to the custom tag.
