Getting java.lang.UnsupportedClassVersionError error

Hi all,
I have implemented a module in struts here i am logging in by using the page login.jsp it contains two textboxes whenever i click on the button the action should go to next page that is display.jsp if the values are eaqual. For this i am checking whether the entered values are available in database or not after that only the action has to move display.jsp page
in struts-config.xml file i wrote
<form-bean name="ProjLoignForm" type="om.ProjLoginFB"/>
<action input="/userlogin.jsp" name="ProjLoignForm" path="/login"
   scope="request" type="action.ProjAction" validate="true">
   <forward name="success" path="/display.jsp"/>
   <forward name="failure" path="/userlogin.jsp"/>
</action>here om and action are packages.
Please help me why it is giving a error like
java.lang.UnsupportedClassVersionError: action/ProjAction (Unsupported major.minor version 49.0Thank you in advance..

Hi,
The class requires JDK/JRE 1.5 but you are probably executing with JDK/JRE 1.4

Getting "java.lang.NullPointerException" error message when trying to run an OATS OpenScript file from Eclipse to Create a record in Oracle EBS

Hello,
I'm trying to run a simple OpenScript script in Eclipse that creates a record (a Supplier in this case) in Oracle E-Business Suite. So I copied the the script file from OpenScript and created it as a Class in Eclipse. Then I created a main class to call the methods within the script class but no matter what method I call (initialize, run or finalize) I'm getting the java.lang.NullPointerException message. The error doesn't seem to be related with any specific line in the script but with the way that I'm calling it.
Should I call the OpenScript class from my main class in a different way? (see my examples below)
BTW, all external .jar files coming with OATS have been added to my project in Eclipse.
1) Here's the main class I created to call the OpenScript method (Eclipse auto-corrected my main class adding a Try and Catch around the method call):
public class Test {
    public static void main(String[] args) {
        nvscript nvs = new nvscript();
        try {
            nvs.initialize();
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
2) Here's the script from OpenScript (the actual script has more steps but I'm just using the first one for a proof of concept):

Compiling from command line I found out that the class definition for oracle.oats.scripting.modules.basic.api.IteratingVUserScript is missing. Do you know what .jar file contains this class?

Getting java.lang.IllegalStateException error with response.getOutputStream

Hi,
I am writer a JSP site for displaying JFreeChart. The main JSP page gets some parameters then the second page out put the chart as binary data with a Java class.
I've located the part which generated the error, as follows:
Code:
OutputStream os = response.getOutputStream(); <--- this line cause the error
response.setContentType("image/png");
ChartUtilities.writeChartAsPNG(os, chart, 400, 300);
(other than it, the JSP does nothing with response or out)

Would any one has some suggestion for me? Your help is very appreciated. Thanks!

Answer
Don't know if this will help--your code worked as is on my system (J2SDK 1.4.1, Tomcat 4.1.12, Linux)--but you're setting the content-type twice, and to two different values. In the page directive, you specify contentType="text/html; charset=8859_1", and then in the scriptlet, you do a response.setContentType ("application/excel");. Try changing the one in the page directive and deleting the one in the scriptlet. The servlet container may be calling getOutputStream() when it sees the text MIME type so it can prepare the out built-in variable.
Also, according to the J2EE design patterns, JSP's should only be used to produce text output. Any binary output (such as Excel files) should be produced with servlets--otherwise, the JSP becomes one big scriptlet (like this one).
If you still want to do this with a JSP, you might want to take out your try ... catch block since you're not doing anything with it. Doing so will allow you to let the servlet container handle the errors (i.e. specify error pages in the web application deployment descriptor). Either that, or at least put the close() and flush()calls in it since they can throw IOExceptions, too. :)
Finally, you should never close the servlet's output stream. Leave that up to the servlet container.

Hi! Maybe a problem with breaklines. Try this: ------------------------------------------------------

%> // make sure that's no breakline an no spaces at the end!!
Re: Breakline problems
Aarthi Sivaram, Apr 19, 2005
In the above code sosStream = response.getOutputStream(); must be removed. Use 'out' instead of sosStream i.e. out.write(""+ibit); If you look at the Java code generated for your JSP, you can find JspWriter out = null ... .. JspWriter calls response.getOutputStream(), thats why when u call getOutputStream, u get IllegalStateException. 'out' variable is available for direct use in all JSP's, like 'request'. So that can be directly used to write.
A quick and working workaround
Leslie Leng, May 20, 2005 [replies:1]
I am not going to discuss the theory behind, as others gurus mentioned before me, are valid.
In short, getOutputStream() could not be used more than once, and also it will conflict with JSPWriter's out.
So, the quick workaround would be, at the end of the JSP page, add the following:
out.clear();
out = pageContext.pushBody();
in example:
catch(Exception e){
System.out.print(e);
out.clear();
out = pageContext.pushBody();
%>

Getting java.lang.IllegalAccessError error , when custom pgs moved R12

I am getting below error, we are recently moved from 11.5.10.2 to 12.1.1, after that the all custom self service pages started giving problems
in pages where I have a OracleCallableStatement (import oracle.jdbc.driver.OracleCallableStatement; ) statement. What do I need to do in order to fix it.
I saw a thread referring to use import oracle.jdbc.OracleCallableStatement ; My Jdeveloper version is 9.0.3.5. I am not sure if that is going to fix this.
Do I need to move to new Jdeveloper version and move the old files into new Jdev and start testing there? please help.

Getting 'java.lang.OutOfMemoryError' while importing process flows.

Hello,
We are getting 'java.lang.OutOfMemoryError' error while importing process flows in our QA environment. This environment is not new. The same process flows were working perfectly fine till last week.
This week we had to delete the project in QA and reimport all the objects. Import went fine for all, except process flows. We could deploy all other objects as well.
We have tried increasing JVM in run_service.sh and owbclient.sh files by increasing -Xmx, -Xmx and Dlimit. We increased as far as 2048M ( This is the max memory available on our server)
We are using OWB version 10.2.0.2 and Oracle 10G over Linux. Did anyone of you face the same issue ? Please le us know the solution.
Thanks
Madhavi

Hi Madhavi,
Which locale language is shown in your OWB client configuration? We had this issue in previous versions (I haven't found it in this version, but I'm used to work with English since these previous versions) So we always adjust Preferences (Tools -> Preferences...) to see Appearance -> Locale -> English.
Try to change the locale language if it's your case.
Regards

Cannot start OC4J instance - after java.lang.OutOfMemory errors

Hi, I have successfully deployed an application (using Oracle Web Services, J2EE - EJB, TopLink ) to a new OC4J instance that we created. We use the OEM web site to manage the start/stop and deploy operations.
Then we tried to run simultaneously 10 clients....against the server app... ran ok for a while and after approx. 5 to 10 min... java.lang.OutOfMemory errors were being thrown at the client.
After a set of OutOfMemory errors, other clients received errors like the ones show below:

Im not sure if this is due to a memory leak or something in my app ? Or does Oracle IAS / Toplink have any such issues for which any possible patches are available ?
Could anyone please direct me in the possible right direction !
Thanks,
Krishna

Hi,
We have had this problem too, it only started after we deployed to production and got some load on our application server. We are using JRun as our application server.
We found that Macromedia (JRun) already addressed the issue in general - that if you get java.lang.OutOfMemory errors, then you need to increase the heap size.
Previously we had been using our own caching mechanism and never ran into this problem. Since we decided to go with TopLink (which has caching) we no longer use our own caching mechanism... but now we have this problem.
We have chosen to use FullIdentityMap for caching, but didn't think we would run out of memory in the JVM. Is there a suggested or minimum JVM memory requirement to run TopLink?
Thanks,
Aaron

CCA 3.2.1 - Changing voice VLAN gets java.lang.nullPointerException

Hi,
I am trying to change the default VLAN number for voice to 32 from 100. At the time of apply changes, I get java.lang.nullpointerException error in CCA. If I make changes to the device command line then Cisco would not support + all command line changes are not showing up in the CCA anymore.
How to get out of this frustrating issue?
I know this is not a Java version or laptop issue because I tried latest version of Java on 3 different PC and all of them report this issue.
Thanks,
Sam

DPL Error: java.lang.UnsupportedClassVersionError

I was trying to use the DPL and ran into a little snag. I'm running my test code from within Eclipse with the jar file added to my class path.
I get the following error:

          store = new EntityStore(myDbEnvironment,"wordCount",config);
          recordByWord = store.getPrimaryIndex(String.class, Record.class);
     }I don't think there is anything wrong with my test program. When I run it with the BDB_je Eclipse project on my classpath (instead of the .jar file built using the ant script) my program works fine.
I'm not quite sure what exaclty what might be going on here but it seems to be something todo with the ClassLoader/ClassEnhancer.
I'm guessing that somewhere in the build of PDL with the ant script the bytecode enhancer is producing 1.6 code. I've worked through a bunch of other test which didn't use the PDL and those work fine with either the .jar file or compiled by Eclipse's "built-in" build process.
To eliminate whether this problem only existed because I built the .jar myself I also tried the .jar file I downloaded in the je-3.2.42.zip file and it had the same effect.
I wanted to try doing everything at commandline and didn't actually get the built to complete but I got a little hint when doing so:

1 errorNow here's the kicker, there's nothing on my system Java 1.6 (Mac OS X is still stuck with 1.5 only) so where did those 1.6 .class files come from???
I'm guessing it is the PDL bytecode enhancer that generated them. That's why I get problems when running from the .jar only because that .jar has enhanced .class files (I saw that the ant build script does some class enhancing), and that's why I don't get the problem when I just build using Eclipse (because in the "plain" eclipse build there's no .class enhancement of the Entity.class has happened).
This explanation seems to fit with the facts but it's only a guess.
Would there be a way to fix this problem? If I just take out the enhancement task from the ant script will that mean not getting the benefit of class enhancement? Or do I still get it in the classloader?
Alternatively, could I rig the enhancer to not output 1.6 byte code?

Hi Kris,
We have not seen this error. There are no class format changes in Java 1.6 (from 1.5), and our enhancer doesn't change the class version. Plus, the com.sleepycat.persist.model.Entity interface is not enhanced by the build.
The biggest clue is this error:
bad class file: /Users/kdvolder/Desktop/downloads/je-3.2.42/lib/je-3.2.42.jar(com/sleepycat/persist/model/Entity.class)
class file has wrong version 50.0, should be 49.0
I'm wondering if the Java 1.4 javac is being used by accident from your path. The main difference between the DPL classes and other JE classes is that the DPL is compiled for Java 1.5 and the rest of the classes are compiled for Java 1.4.
After getting this error could you please send the output from these commands?:
java -version
javac -version
If the javac version is 1.4, that explains what's happening. I also suggest looking for Java 1.4 in your Eclipse path.
Otherwise, if it helps (although I don't know why it would) you should be able to comment out the use of the <enhancer> task in the build file, as long as you don't try any explicit enhancement yourself. We enhance our built-in proxy classes during the build only to make them compatible with enhanced application classes. I'm not saying that the class enhancer is to blame for this error, but if removing the enhancer helps, please do that as a workaround for now, and that will give us more information about the error.

I am getting a "java.lang.RuntimeException: Error loading file:....NULL content-length." message when attempting to load a jnlp file

I am the applications administrator for an instance of Galaxy server. In Galaxy there is an option / plugin to opne a BAM file via the Integrative Genomics Viewer (IGV) created at the Broad Institute. When invoked it downloads a jnlp file and launches IGV and then is supposed to open the BAM file in the viewer. However, when it attempts to open the BAM file I get the following error:
"An Error occurred while loading: http://galaxy/display_application/52cef830ad5766ca/igv_bam/web/29212308ff643a94/data/galaxy_52cef830ad5766ca.bam

UPDATE
Compiling from command line I found out that the class definition for oracle.oats.scripting.modules.basic.api.IteratingVUserScript is missing. Do you know what .jar file contains this class?
Thanks.

Exception in thread "main"
Even if i try to recompile it in command prompt and run, i got the same error.
please suggest me how can i overcome this problem.

UnsupportedClassVersionError means that you are trying to execute a class for a newer version of the JVM on an older version of the JVM.
Version 48.0 is for Java 1.4, so you have compiled your class with JDK 1.4.
The computer you are trying to run the class on, has an older version of Java than 1.4 - check it!
Try recompiling your source files with the "-target" switch, for example if you're running on Java 1.3, try compiling with:
javac -target 1.3 ... FileLocking.java

Java.lang.UnsupportedClassVersionError with ADF and Websphere

I'm trying to get an app running with ADF/Tomahawk/MyFaces/Facelets going on Websphere 6.0. However Websphere is running with a 1.4.2 JVM instead of 1.5 so I get an error when it comes to the ADF NavigationHandlerImpl which has been built with Java 1.5. Is there a Java 1.4 version of ADF faces I should have downloaded somewhere?
Hints appreciated.

This is often caused by having a class defined at multiple
locations within the classloader hierarchy. Other potential causes
include compiling against an older or newer version of the class
that has an incompatible method signature.

Hi,
you will have to compile the application with JDK 1.4 in this case. This should work for JSF and ADF Faces.

Java.lang.UnsupportedClassVersionError: per/model/mac/Hrxss_Per_Subtype_Inf

Hi,
I have copied the essper application from inactive dc's and changed the visibility property to be derived dynamically depending on the subtype being displayed. After having deployed the essper, I am getting the java.lang.UnsupportedClassVersionError: (com/sap/xss/per/model/mac/Hrxss_Per_Subtype_Info) bad major version at offset=6.
My compiler compliance level is 1.4 and I am deploying the applications using jdk1.4. Could you please assist?

Thanking you in advance.

hi,
you may get some idea from below lines
I changed the compiler complience level to 1.4 and deployed the application using jdk1.4. However the error was still there. When basis team checked the development config for PCUI_GP, it was sitting on SP03 which they then updated and the problem was fixed. Now I am getting a java.lang.UnsupportedClassVersionError on a different wd componet.
Thanks !

Wlst doesn't start- java.lang.UnsupportedClassVersionError

i get the following error while running wlst
>>
bash-3.00$ java weblogic.WLST
Initializing WebLogic Scripting Tool (WLST) ...
Problem invoking WLST - java.lang.UnsupportedClassVersionError: Bad version number in .class file

though it used to work perfectly fine ago, just couple of days back it started having these problem...

Hi,
It may be possible that recently you might have installed a Lower version of JVM in the same BOX.
So please verify that by doing the following:
1). Open a Shell prompt and then type:
java -version
java version "1.6.0_24"
Java(TM) SE Runtime Environment (build 1.6.0_24-b07)
Java HotSpot(TM) 64-Bit Server VM (build 19.1-b02, mixed mode)2). Make sure that this is the JVM which you want to invoke the WLST ....because it is possible that the weblogic.WLST is compiled in a higher version of the JDK which you might be seeing in your OUTPUT of the above command.
3). So please make sure to set the PATH variable by adding your Latest version of JDK (example JDK 1.6) AT the beginning of the PATH like following:
export PATH=/home/myuser/myJDKs/jdk1.6.0_2/bin:$PATH
echo $PATHThanks
