Hi all,
Getting above exception only in Weblogic 9.2
JDK Version : jdk1.5.0_16
jena-2.5.6.jar
xercesImpl-2.6.2.jar
SAXParser is working fine in JBoss with same jdk and jar version. But it's throwing above exception in webloigc9.2 (Windows ) and more over, if i add -Xbootclasspath and specify the xercesImpl-2.6.2.jar file it works in weblogic 9.2 also..
Is there any other 'good' solution for this??? I feel , this issue is related to classloader but dont know how :(.
Regards
Anand

Hi,
try to add your jar to the PRE_CLASSPATH.

Java.lang.NoClassDefFoundError: org/apache/xerces/parsers/SAXParser

We are trying to evaluate Weblogic 6.1 Beta version.
We have tried a setup that is working in WebLogic 6.0 sp1 version,
but the same setup fails in the Beta version.
We get ...
java.lang.NoClassDefFoundError:
org/apache/xerces/parsers/SAXParser
We had not specified any addl. jars in the classpath
in 6.0 sp1 version. But this fails in the Beta version.
Could someone tell if this is a known bug in the Beta release and
suggest a solution or tell if this will be fixed in the actual version
when it is
released in July?
Thanks.

Alternatively u can set the parameters to look at the right parser when uneed
it. This can be done by:
System.setProperty("javax.xml.parsers.SAXParserFactory","org.apache.xerces.jaxp.SAXParserFactoryImpl");
System.setProperty("javax.xml.parsers.DocumentBuilderFactory","org.apache.xerces.jaxp.DocumentBuilderFactoryImpl");
System.setProperty("javax.xml.parsers.SAXParser","org.apache.xerces.jaxp.SAXParserImpl");
This is far from being recommended for the following reason:
The JAXP factories cache the classes used to instantiate the factories,
therefore you cannot changed dynamically these properties at runtime, you
will have absolutely NO guarantee that this will work. If a factory is
instantiated before yours, it will use this one. Additionaly, Weblogic
already defines these properties at startup so that they refer to their own
factories that can look into the XML registry.
Consider these properties as being read-only. Chance are that you will mess
up everything if you modify them.
If you need to define a specific parser (such as crimson), then put crimson
in your system classpath and set the XML registry appropriately.
If you want to take a look at jaxp strategy. Use the JVM
property -Djaxp.debug=true.
As well use -Dweblogic.xml.debug=true for Weblogic XML related info.

Org.apache.xerces.parsers.SAXParser

After compiling ,while trying to run my program is giving on the console window.
"org.apache.xerces.parsers.SAXParser" instead of what it is supposed to do .
i am using java 1.4.2 and xerces 2.7.1
Can Anyone point what is the problem with this.
thanks

are you calling toString on the parser?
'what it is supposed to do" -- you know because it worked with a previous version of xerces?
What code is generating:
org.apache.xerces.parsers.SAXParser
?

Org.apache.xerces.parsers.SAXParser class, where do I find it?

I don´t know if this is the right place to ask, but maybe someone will know:
I need the class org.apache.xerces.parsers.SAXParser that should be included in the Apache Xerces project.
Here is the API: [http://xerces.apache.org/xerces2-j/javadocs/xerces2/|http://xerces.apache.org/xerces2-j/javadocs/xerces2/]
and here is the download section: [http://xerces.apache.org/xerces2-j/download.cgi|http://xerces.apache.org/xerces2-j/download.cgi] . I have downloaded Xerces-J-bin.2.9.1.zip but the class isn´t included.
My book I am reading is using that class and says it is a part of the Xerces project.

Hi,
Well, I do not know what you are looking at but it definitely is in the src : Xerces-J-src.2.9.1.tar.gz
So if worst comes to worst build it from the source. However, from the bin you downloaded there are several jars and the class you need to import is in xercesImpl.jar.
Regards.

I thought that the method in question was the getTextContext() method. ?

This is the method that contains the line in question(line 184 is last line):

i am new to java. I am trying to parse an xml document. the code is as follows:-

after this i am trying to traverse using treewalker :-

               TreeWalker treeWalk = docTrav.createTreeWalker(docElem, NodeFilter.SHOW_ELEMENT, new ConfigNodeFilter(), false);

any help will be appreciated.

"In DOMs which support the Traversal feature, DocumentTraversal will be implemented by the same objects that implement the Document interface. "
My guess is that the DOM parser you are using doesn't support the DocumentTraversal interface which is why you can not cast to that class.

Java.lang.IllegalArgumentException: org.apache.fop.svg.SVGElementMapping

I believe its the problem with the class loaders.
I even configured my orion-web.xml to load the local classes and following is the conf file:
<orion-web-app
     deployment-version="9.0.4.0.0"
     temporary-directory="./temp"
     internationalize-resources="false"
     default-mime-type="application/octet-stream"
     servlet-webdir="/servlet/"
>
     <web-app-class-loader search-local-classes-first="true" include-war-manifest-class-path="false" />
</orion-web-app>
I have loaded the most stable jar files(fop-0.20.5) required for the generation of PDF.
The same application runs well in JDeveloper(10.1.2.0.0)
Could somebody help me out with this.
Its very urgent.
Need to be able to deploy this by evening.
Thanks

This means the code loading the element mappings does not recognize
the SVGElementMapping as an ElementMapping, as it expects. The most
likely reason is that they are loaded from different class loaders -That was the reason of my simple suggestion above.
There are many ways that you can try now.
One way is to put all libraries in your war into ORACLE_HOME/j2ee/home/applib. Also remove the following line
<web-app-class-loader search-local-classes-first="true" include-war-manifest-class-path="false" />
since this search-local-classes-first is problematic sometimes.
It might be nice if you can verify that the classloader that loads SVGElementMapping is different from the one that loads Elementmapping at that point of code.
Now Could somebody help me out as this is the problem of OC4J .Hmm, I would not say "problem of OC4J". A usage error or a false incompatibility at worst. "False" because there should be many normal and standard ways to make it work.

So what are the contents of the relevant files?
It looks like an error at Tomcat startup:
Do you need any Portlet library jar files in your web app?
However I would suggest that you would have more luck at the other end of a google search on the error message.
The [Liferay wiki |http://www.liferay.com/web/guest/community/wiki] seems a good place to start.

Java.lang.NoClassDefFoundError: org/apache/log4j/Logger when creating ABCS

Hi,
I am trying to create a AIA Service Component Project using 11.1.1.5 jdev.
The following error occured while executing this line: C:\XXX\Developement\AIA\build.xml:78: Could not create type evaluateFTL due to java.lang.NoClassDefFoundError:org/apache/log4j/Logger.
do I have to put some jar files anywhere in jdeveloper ? Please advice.
Thanks
Sai

Hi,
The jar to be added is com.bea.core.apache.log4j_1.2.13.jar located in $MIDDLEWARE_HOME/modules
Cheers,
Vlad

Error: java.lang.NoClassDefFoundError: org.apache.struts.taglib.html.BaseHa

I am using JDeveoper10.1.2 with JHeadStart
I am developing the OrderEntry application using ADF with Struts. Whenever i make the "Gender" field as Radio Group Button i get the following error message
Error: java.lang.NoClassDefFoundError: org.apache.struts.taglib.html.BaseHandlerTag
Please help what could be the cause.

I have another way to solve this problem!
When these errors happened, u double clicked on the error line in Embedded OC4J Server log window. The error will lead to the blue marked line, may be:
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html"%> (1)
or
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean"%> (2)
If line (1) marked, change the prefix="html" to prefix="html1"
If line (2) marked, find the lines like <bean:message key="link.something_here"/>
and change to <bean:message key="link.something_here1"/> and the correspond line of this key in the ApplicationResources.properties file of the project
I successfully using this way but only if one error happend at a time or two errors from two kinds of error
This way is not as good as the previous way mentioned in previous post.

The relevant jar file, commons-digester.jar is in the the WEB-INF/lib folder, just like all the other commons-*.jar files.
My CLASSPATH variable doesn't contain anything except a an XMLSpy jar file.
I'm running WLS 8.1 SP2.
Any help/hints are greatly appreciated.

I would set "prefer-web-inf-classes" to "true" in your "weblogic.xml" file. Without this, you may be getting classloader confusion with some of the commons jars that are used within WebLogic.
