VerifyError

I'm switching from jdk1.3 to 1.4.1_01 and I'm getting a java.lang.VerifyError when I dynamically load a class into my own Classloader and then try to access the Constructor.
Class guiClass = myLoader.loadClass(className);
Constructor constr = guiClass.getConstructor(new Class[] { resourceBundleClass });
The 2nd line is where the error occurs. I deleted all my .class files and recompiled, but that didn't work. This worked fine under JDK 1.3.
Any thoughts?

I figured it out actually.
Turns out I had 2 versions of the same class file. I compiled one group into a jar, which I used to compile the majority of my classes, but then when I ran I didn't use the jar, I used just the regular class files. The files in the jar must have gotten old and there was a discrepancy. By rebuilding my jar and recompiling everything, it worked.
Thanks.

VerifyError trying intantiate the oracles TransformerFactory for XSL

Hi,
When I try intantiating the Oracle4s TransformerFactory, I obtain a verifyError, next is the error message.
(class: oracle/xml/jaxp/JXSAXTransformerFactory, method: reportConfigException signature: (Ljava/lang/Exception;IILjavax/xml/transform/SourceLocator;)V) Incompatible object argument for function call
This occurs, setting the environment variable "javax.xml.transform.TransformerFactory" to values null and "oracle.xml.jaxp.JXSAXTransformerFactory";
With this error it4s imposible process any xml with an xsl file.
I would regard any help
Thanks,
Rodolfo

It is the content of the "type" attribute of the "xml-stylesheet" processing instruction that leads to a null return value. W3C says the following at http://www.w3.org/TR/xslt20/#xslt-mime-definition :
There is no experimental, vendor specific, or personal tree predecessor to "application/xslt+xml", reflecting the fact that no applications currently recognize it. This new type is being registered in order to allow for the expected deployment of XSLT 2.0 on the World Wide Web, as a first class XML application.
So, for the time being, you should use the good old "text/xsl" in place of "application/xslt+xml".

Java.lang.VerifyError - Incompatible object argument for function call

Hi all,
I'm developing a JSP application (powered by Tomcat 4.0.1 in JDK 1.3, in Eclipse 3.3). Among other stuff I have 3 classes interacting with an Oracle database, covering 3 use cases - renaming, adding and deleting an database object. The renaming class simply updates the database with a String variable it receives from the request object, whereas the other two classes perform some calculations with the request data and update the database accordingly.
When the adding or deleting classes are executed, by performing the appropriate actions through the web application, Tomcat throws the following:
java.lang.VerifyError: (class: action/GliederungNewAction, method: insertNewNode signature: (Loracle/jdbc/driver/OracleConnection;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;I)V) Incompatible object argument for function call

 at javax.servlet.http.HttpServlet.service(HttpServlet.java:853)
 at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:247)
...The renaming works fine though. I have checked mailing lists and forums as well as contacted the company's java support but everything I have tried out so far, from exchanging the xerces.jar files found in JDOM and Tomcat to rebuidling the project didn't help.
I just can't explain to myself why this error occurs and I don't see how some additional Java code in the other 2 classes could cause it?
I realize that the Tomcat and JDK versions I'm using are totally out of date, but that's company's current standard and I can't really change that.
Here's the source code. I moved parts of the business logic from Java to Oracle recently but I left the SQL statements that the Oracle stored procedures are executing if it helps someone.

After further googling I figured out what was causing the problem: in eclipse I was referring to external libraries located in eclipse/plugins directory, whereas Tomcat was referring to the same libraries (possibly older versions) in it's common/lib directory.

VerifyError: Error #1014 (class could not be found)

I have a Flash Pro CS5 project that I have built some classes for in Flash Builder using some of the mx classes, like ArrayCollection and HTTPService. I have a Flash Project in my Flash Builder 4.0 pointing to the Flash Pro project. I started out by adding the Library Path to the Flex SDK 4.0.0 in my Flash project paths. Things seemed to work fine at first but now I am getting the following error:
VerifyError: Error #1014: Class mx.collections::ArrayCollection could not be found
If I change all my ArrayCollections to be just Arrays, then the same error just cascades down the list of "missing" mx classes, like HTTPService, etc. I individually added the the framework.swc, the rpc.swc and even the framework_rb.swc and rpc_rb.swc files to the paths but with the same error results.
I'm trying to set up a relatively smooth workflow between Flash developers and Flex developers on my team but this is a huge roadblock.
I have looked all over and not found a good solution for this problem. Can anyone help?
Dana

I figured out a solution. It had to do with conflicting or out of order library paths, I think. There were several paths to other projects in the project and Flash Pro global paths. I think some of them are automatically added by either the FP or the FB IDEs. When I removed all of the unnecessary paths, then it compiled just fine.

VerifyError on OC4J (9.0.2.1.0)

We've been getting a smattering of these errors lately, and once they happen, we have to bounce our OC4J process. Sometimes they can return in 5 minutes, sometimes not till the next day.
I just found out that the support staff applied a patch shortly before this problem started occuring. (Oracle Security Alert #68) -- which contained bug fixes: Oracle9i Database Server (9.2.0.5) Bug 3811906 and IAS9i (1.0.2.2) Bug 3835781
The problem is intermittent, and attacks different JSPs all the time. We can't reliably reproduce it, in order to provide a concrete test case.

VerifyError #1025 - default xml namespace and getter function

I have narrowed the problem down to a a few lines. I have
created a simple example of the problem...
// TestClass.as

private var _testVar:String;
public function TestClass() {

// Test.fla - frame 1

var myTestClass:TestClass = new TestClass();

I get the following error...

However if I take out the default xml namespace line, and
create a new namespace it will work.
var testNS:Namespace = new Namespace(testXML.namespace(""));
_testVar = testXML.testNS::node2.testNS::node3;
Thoughts??? It's driving me crazy. Thanks in advance...

The attribute should be in the element's namespace. If I run this snippet on the timeline, it outputs the correct values.
var xml:XML =

VerifyError: Error #1053: Illegal override of isRelatedObjectInaccessible in RemappedMouseEvent.

I am having trouble running AIR applications with Flex SDK 4.0 (and 4.1). Here is what I am doing:
On OS X 10.6.4 using eclipse with Flex Builder 3 installed I create a new flex project with AIR.
I have eclipse setup to use the SDK flex_sdk_4.1.0.16076.
I clean the project and run it and get a window telling me:
VerifyError: Error #1053: Illegal override of isRelatedObjectInaccessible in RemappedMouseEvent.
The application fails to start after that.
When I switch SDKs to Flex SDK 3.3.0.4852 and clean, the applications starts as expected.
I have tried to run adl from the command line using the artifacts in the bin-debug folder and I get the same error.
I am stumped here, does anyone know what else I can try?
Thanks
-Lucsa

Hi Lucas,
Are you running into this error when compiling a brand new flex project for AIR? If so, I suspect something went wrong with your AIR overlay. Please see the How to Overlay the AIR SDK for use with the Flex SDK tech doc. Note that these instructions reference AIR 1.5, but they are the same for AIR 2.
Let me know if you have any questions about the overlay process or if you've already done all this.
Thanks,
Chris

First, thanks a lot for the quick reply. I appeciate this. 
 
1. You are right, com.mercury.jdbc is a repackaging of DataDirect's driver. 
2. Full Stack dump: Ok, I suggest yo first contact DataDirect and show them
this exception. However, I have a suspicion that your
version of the driver has some conflicting versions of
some internal security classes from the versions of the
DataDirect drivers that we ship, rebranded as BEA drivers.
So, try going to your server\lib directory, and renaming
the wlutil.jar, wlbase.jar, and wlsqlserver.jar so WebLogic
won't use them. Let me know if that makes your odd exception
go away. Also, you might consider using our drivers. Get
the latest driver package and you will have DataDirect's
latest and best, including all the BEA-found bugs fixed.

500 Internal Server Error :java.lang.VerifyError

Ok, so I have deployed my BI Bean RC2 tutorial app from Jdeveloper RC2, with no errors during deployment.
It also runs fine from jdeveloper embedded oc4j.
When I try to call the deployed application in my browser I get this:

I am able to run all of the samples that comes with oc4j.

Can anyone point me in the right direction to solve this?

The guys over in the J2EE forum came with this answer. Please note that they refer to Jdeveloper 9.0.3.
I don't really know how to interpret that, as the RC2 Jdeveloper is 9.0.2.7.86, but anyway, her goes:
<snip>
It seems like you are using JDeveloper 903, is that right?
Select Help->About from the Jdeveloper menus
If you are using Jdeveloper 903, read on:
This is a known issue. 903 Jdeveloper is bundled with J2EE ORB (IIOP.jar) from Sun to allow EJBs communicate using RMI/IIOP. In addition, we also have Visibroker ORB (VBJORB.jar) in the classpath. Sun has implemented CORBA 2.3.1 specification and Visibroker I believe has implemented CORBA 2.3.0 spec. The signature of one of the methods in class org.omg.PortableServer.AdapterActivatorPOA has changed between the two releases and hence the problem.
We are trying to move away from Visibroker ORB and have requested OLAPI team to remove all dependencies on Visi ORB. Although there is no known dependencies on it, there seems to be dependencies because the idl compiler (from Visibroker) is inserting referces to Visibroker code.
To work around :
Remove/rename iiop.jar file in ORACLE_HOME/J2EE/HOME directory. Be warned that EJB's wont work if it is renamed or removed.
This should only be considered as a temporary work around until we decide our next steps.
</snip>
Use at own risk..
The error reported in this thread disappeared with this workaround, but unfortunately I got another one:
500 Internal Server Error

Upgrading from j2sdk-1_4_2_07 to jdk-1_5_0_06 java.lang.VerifyError

HI,
i'm trying to upgrade my application from jdsk 1.4.3.07 to jdk 1.5.0.06.
The applications works fine compiled with 1.4 and run with 1.4 and 1.5, but where i try to compile and run with 1.5 i received a:
java.lang.VerifyError !!!
I'm use log4j 1.2.13 and gnuregexp as external library.
Has someone an idea ?
thanks in advance
Carlo Mossa ([email protected])

Try to use -target 1.4 option of javac.
Default mode in jdk1.5 is -target 1.5 and it generates classes which are not supported by 1.4.

You can't inherit from a final class.
So - are you trying to inherit from a final class?

Java.lang.VerifyError when using ant 1.6.2

In short, I get the VerifyError when deploying my .ear in Weblogic 8.1 SP2. I have nailed down the issue to this:
I compile all my code using Ant 1.6.2. If I package the code up using ant 1.6.2 I get the VerifyError. If I pacakge the code up using ant 1.4, all is well. Note that when I deploy the 1.6.2 packaged ear file on Windows, all is well also.
During the ant package target I assembly the war and ear using the core war and ear tasks.
We are using precompiled JSPs in the war file. It seems that WL8.1 wants to recompile the JSP file. I am not sure why - the ant 1.4 packaged ear does not want to recompile the same JSP.
The detailed error is:
Servlet class jsp_servlet._portal.__capitalmarketsoverview for servlet /portal/CapitalMarketsOverview.jsp could not be verified.
java.lang.VerifyError: (class: jsp_servlet/_portal/__capitalmarketsoverview, method: _jspService signature: (Ljavax/servlet/http/HttpServletRequest;Ljavax/servlet/http/HttpServletResponse;)V) Incompatible object argument for function call.>
Any help is appreciated,
Harry Duin

Hello,
I could not find an easy way to get the wls version of ant to start using the tasks you mention from ant 1.6.2.
I tried defining the tasks using taskdef and also adding them to wls ant.jar and updating the deafult.properties file but the ant complained about unexpected elements in the build.xml file where I added the new tags (e.g import)
If your really up against it you can try adding wls tasks to ant 1.6.2, they are listed here:
http://e-docs.bea.com/wls/docs81/toolstable/ToolsTable.html#1009580
Although I could not located exactly which jar they are in. Good luck.

Java.lang.VerifyError in code generated by Prototype 1.2

I managed to get a java.lang.VerifyError from a class generated by prototype 1.2. A short test case follows: (It looks like the compile knows it can call .intern() on the result of the
?:, but the verifier thinks the bytecode does something wrong..)
import java.util.Stack;
public class Case
public static void main(String[] argv)
Stack<String> bar = new Stack<String>();
String foo;
// Compiles, but causes verify error
foo=(bar.empty()?"":bar.peek()).intern();
// The following two work fine
foo = (bar.empty()?"":bar.peek().intern());
foo = (bar.empty()?"":(String)bar.peek()).intern();

Hi,
I've noticed the same behaviour (java.lang.VerifyError) with code that uses extra parentheses on the return
statement, i.e.:
return(object);
instead of:
return object;
Interestingly, parentheses also seem to affect your above example. If I change it as follows:
public class TestGenericsBug
public static void main(String[] argv)
Stack<String> bar = new Stack<String>();
String foo;
// Compiles, works fine
String tmp = bar.empty()?"":bar.peek() ;
foo = tmp.intern();
// The following two work fine
foo = (bar.empty()?"":bar.peek().intern());
foo = (bar.empty()?"":(String)bar.peek()).intern();
The code compiles and runs. If, however, extra parenteses are added:
package test;
import java.util.Stack;
public class TestGenericsBug
public static void main(String[] argv)
Stack<String> bar = new Stack<String>();
String foo;
// Compiles, but causes verify error. Extra Parentheses ?
String tmp = ( bar.empty()?"":bar.peek() );
foo = tmp.intern();
// The following two work fine
foo = (bar.empty()?"":bar.peek().intern());
foo = (bar.empty()?"":(String)bar.peek()).intern();
The bug is back!
