it seems that the class "org.apache.xml.serializer.SerializerTrace" is missing, is it? and i have add the path of "xalan.jar" in xalan-j_2_7_0 dic to the "CLASSPATH" enviroment parameter, but the class of "org.apache.xml.serializer.SerializerTrace" could not be found at that xalan.jar file.
could anyone help me overcome this error, thanks.

I met the same probem as you. Finally, I sove it. You can do as follows:
Put serializer.jar, xercesImpl.jar and xml-apis.jar into classpath also or put them into ANT_HOME/lib.
It is not enough to put xalan.jar only as some guid said:-), you need put all the jar files existed in <xalan-j_2_7_0> after you unzip the xalan-j_2_7_0-bin.zip file.
Good luck.

i am unable to use TextAnim - no matter what. could anyone please send me a complete source code of a running example?
whatever i do - i run into an exception or a compile error. (for example - addChild cannot be used in SDK4.0 but i cannot use something else with the TextField component).
some TextAnim tutorial:
http://www.actionscript.org/forums/showthread.php3?t=226682
and the project website:
http://code.google.com/p/textanim/
so please send a running source code. much appreciated!
thanks,
ronnie

ok, progress was made - thanks for the tip Ben!
on SDK 4.1 it now compiles and runs but the screen stays white. following is the complete MXML code, feedback will be VERY welcome.

Tomcat 4.0 can run example but cannot run my servlet!

I can run examples (both servlet and JSP) under Tomcat.
Now I have servlets class file in
C:\jakarta-tomcat-4.0.1\webapps\vpsystem\WEB-INF\classes\agent\bookmark\BookMark.class
but I cannot see "http://localhost:8080/vpsystem/agent/bookmark/BookMark" in IE.It tell me no resource found.
It's the matter of web.xml?It's the matter of server.xml?Or any another?
Please someone help me out.
Thanks!

Maybe both. You should show how you have configured the web application in server.xml and the servlet in web.xml in order to be able to help you

I cann't run web browser on my xi host

Hi Guru's,
I have installed XI(3.0) successfully on Windows 2003 then went for post installation.I need to be importing the exchange proile.I cann't run a web browser on my XI host using this URL http://<j2ee_host>:<j2ee_port>/exchangeporile.How
can i copy the file exchange_proile.xml from the XI to a host were a web browser runs.
I have stucked the importing exchangeprofile,so could anybody please help on this regard.
Regards,
Venkat.

Hi -
Are you sure you have the right j2ee port in the URL? To confirm, you can check SMICM->Goto->HTTP Server->Display Data for the J2EE HTTP port.
The URL for exchangeProfile is http://<j2ee_host>:<j2ee_port>/exchangeProfile
>>>can i copy the file exchange_proile.xml from the XI to a host were a web browser runs.
Yes, you can do that (e.g. copy the xml to your local pc, access exchangeProfile URL and import).

Jin

The attached VI works when I run it initially creating the XML file, but when run after the XML file is created, it's not updated. What am I doing wrong?

The attached VI works when I run it initially creating the XML file, but when I change data and run after the XML file is created, it's not updated with new data. What am I doing wrong?
Thank you.

That looks like the logic which was written into the VI
Inner true/ false case:
(file exists : false) write to XML file, unflatten for display
(file exists : true) read from XML file, unflatten for display
At no time when the file exists (true case) is the XML file updated...

Running examples from J2EE Tutorial

Has anyone been successfully running examples from
J2EE Tutorial on Creator?
I tried to import the JSP but Creator complains that it is
not an XHTML document. Clicking on the 'Convert to XHTML'
button or 'Preview...' button does not seem to do anything.
Openning the Source panel shows parsing problems on
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
Does anyone know how to run these in Creator correctly?
- weijyh

Yes,
It runs successfully....
I have download the examples from Sun,
unzipped It into my Projektfolder and open it in Creator, start it and works fine ...
No error messages ....

Could anyone give me some advices to deal with this problem? Thanks

LOL.... i ran into the same problem with Tomcat 5.5... it's quite an idiotic problem cuz like you gotta hunt everywhere to figure out why it don't work... reason is cuz those brainchildren at Apache.org who make Tomcat also make the missing Jar file but forgot to include it with Tomcat... duh... :-p
any way... visit this site... http://xml.apache.org/xalan-j/
download the zip file and extract it (follow the instructions)
you only need to copy the xalan.jar file to your Tomcat 5.5's <installpath>\common\lib folder...
then that problem will be fixed...
have fun... :-p

PL/SQL XML Parser - problem running example

Oracle 8.1.5 database on NT
When i try running the example with command:
SQL*Plus> exec domsample
('//SERVER_03/ORACLE/xml_tmp','family.xml', 'err.txt');
I get the following error:
ERROR at line 1:

If i use backward-slashes '\' which should be OK for NT i get:

I tried using a directory (create directory ...) but this
results in the same error.
Thus anyone now how it should be done?
Thanks

The use of "//" or "\\" appears to be a bug in JServer. It has
been filed. You should not specify the path as a shared
directory as a workaround.

Error while running a sample XSQL from XML bible book from Steve Muench

I am running the sample XSQL code from Chapter 03, which deals with exporting XML and transform into SQL statements. I'm using JDeveloper and I believe I've setup libraries and HTML root directory etc. I'm getting the following error:
XSQL-011 Error processing XSLT stylesheet.
XSL-1009 Attribute xsl:version not found in xsl:stylesheet.
Can I get some help in fixing this error?
Thanks a lot,
Murali
null

Hi,
This is the example I took from Steve Muench's book.
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text"/>
<xsl:template match="/">
</xsl:template1>
</xsl:stylesheet>
As you can see, I do have the version=1.0 attribute. Why is it complaining still?

I'm not sure what exactly you're trying to do.
Once you install commcli, you should be able to use the command-line tools. They work, but you have to have been consistant in giving answers to all the questions asked.
You also may not share the amadmin password with any other password. It must be unique.
There is no need to compile anything to get Messaging Server to work, or to provision it with commcli.

J2EE client cann't run: javax.naming.NameNotFoundException

I have such a problem with Bea weblogic 6.1 EJB Server, trying to connected it from Tomcat (don't know, if it would work anyway):
If I try to lookup with standard "java:comp/env/ejb/ObjRemote", it tell's me there is no comp/env/ejb Object !
All examples/docu I read for this topic told me to call lookup("ObjRemote").
So look it up this way: simply with this name lookup("ObjRemote")...

Cann't run example of transformXML in XML dic of jstl1.1 standard-examples
