Could you post or describe the source code causing this error?

What Java and what Windows are you using?

The problem was solved folks!
I simply install the JDK (before i got installed only the JRE) and the problem doesn't happened anymore!
Thanks for all!!!

Best regards!

I'm another newbie in the same boat--installed Jabaco, then created a hello world app. The app ran normally on the machine that I installed Jabaco on. So I decided to compile it as a .jar and try it on another machine.

Since the other machine had no java components on it whatsoever, I installed JRE v23. Then I tried running the .jar.

As mentioned above, the NoSuchMethodError is immediately displayed, but if I hit ignore, the hello world app functioned normally.

The posting above indicates installing JDK "solved" the problem, but that doesn't really work for distributing a program. I was under the assumption all I would need is the JRE to run a jabaco generated app. Can anyone clarify this for me? Or are we looking at a recent bug here, maybe with JRE v23?

Thanks

Jabaco executable Jar files should be runnable with just a JRE.
I am not aware that JDK and JRE differ in their *.jar libraries.

It would be an interesting test to try an elder JDK.
Any volunteers out there?

YES!!! I can be a volunteer, with pleasure, but i need all detailed instructions on how to do the tests. I´m a newbie too in the "Java World" and "JABACO World" much more... rsrs


Thanks.

We had occasional startup problems until early 2010. Most of them could be pinned down to Java installation problems.
You can find related posts using the search facility of this forum (look for "JAVA_HOME").
Java has Windows registry entries under HKEY_CURRENT_USER/Software/JavaSoft and HKEY_LOCAL_MACHINE/Software/JavaSoft
As far as I know, Java evaluates both the registry and the environment variables to find out its home.
Tricky users with several Java installations usually have little problems to confuse Jabaco,
especially after manually copying complete Java branches without properly updating the registry.

Non-Windows platforms like Apple Mac or some Java-enabled smartphones might pose additional difficulties.
Their java run-time libraries might lack certain classes called by Jabaco.

Please post your findings here

More Info!



I can confirm that this problem is because of the recent java upgrade to v23. As I mentioned before, the test app ran perfectly on the machine I installed Jabaco on. That machine did not have Java on it, so the Jabaco installer installed it for me. It installed an older version (possibly v16?) apparently. I didn't notice this, but today Java automatically prompted me to install the latest v23 version. So I did. Since then, this machine exhibits the exact same startup problem as my other machine running v23, as described above.



So at least we know who to blame, in a vague sort of way...

JRE 6.23 is running OK on my Windows XP system:

Source code

 
1

3

java version "1.6.0_23"
Java(TM) SE Runtime Environment (build 1.6.0_23-b05)
Java HotSpot(TM) Client VM (build 19.0-b09, mixed mode, sharing)


I haven't encountered any problems, neither running *.exe nor *.jar binaries.

What date and size has your Jabaco.jar framework file in the Jabaco program directory?

It is just a wild guess, but it might help to try this Jabaco.jar

The download can be found here. Avoid releases smaller than 500kByte. They are incomplete.

The original error message indicates that something is wrong with the graphical user interface (Java Swing)
It might be that your Java installation has peculiar swing.properties (see here) which are incompatible with Jabaco.
What Windows are you using?

XP SP3. I'll see what I can do with the new framework file, not sure what I'm supposed to do with it, replace my existing one I assume...

XP SP3 is OK. That's what I am using as well.

To experiment with the Jabaco.jar, save your existing Jabaco.jar (rename it with a date postfix) and replace it by the downloaded one.
Recompile your project and test the result.

What combination of local language (English, Spanish, Urdu, ...) and character set (ISO 8859-1, ...) are you using?
Is there any notable difference between the system where you run the IDE and the system where you started the executable?

Have you checked the Java issues mentioned in the Forum posts (search for "JAVA_HOME")?

Do you get your error message for your binary regardless if it is in *.exe or in *.jar format?

Success!

Ok, here we go. Originally, projects worked fine on jabaco installation. After automatic upgrade to 6.23, the startup error appeared, but projects still execute after hitting "continue."



When compiled as either an .exe or .jar, the error still pops up, on both the original machine, and also on another that has no jabaco installed, only JRE v23.



Both machines are XP SP3 with really no differences, English (US) with whatever character set would be standard (not familiar with that...)



I looked through the JAVA_HOME thread, but didn't see any of those issues. They also seemed more to describe not being able to get Java to start up. In this case, everything starts and runs normally, except for the initial error pop-up.



Finally, I downloaded the most recent 500K+ Jabaco.jar from this site, renamed my old, and copied it into install directory. Nothing appears to have changed--when running project in IDE, the error popup occurs. When compiled as either .exe or .jar, the pop-up still appears, on both of my machines. But the project always runs successfully after that.



What is odd here is that I couldn't have made a more clean installation--by chance the machine I installed Jabaco on is a brand new Windows install, with almost nothing else installed. Windows updates, that's about it. I guess I'm using Microsoft Security Essentials as an anti-virus, don't know if that could interfere...



I'll look on the Sun site to see if it is possible to download previous JRE versions, and start stepping back until things being working again, just as an experiment...



Thanks!

More Info: If I create a SDI project with just form and a label, the pop-up error occurs.

If I create a console application with a single added line of code MsgBox "Hello!", the application runs with no error pop-up.

Hello scGuy!

Here i experienced the same error but i solved this installing the Java SDK. I know that this is not an requirement to Jabaco, but you can try this...
I hope that this be helpful.

Best regards.

Console applications don't use Java swing.
This gives rise to the suspicion that there could be something wrong with the Swing configuration.

Frankly speaking, I'm rather clueless on this one!

Sorry!

Well, thank you for your efforts in any case. Maybe a future JRE update will fix the problem. Searches on google indicated that perhaps swing was updated, and did not maintain backward compatibility... the good news is that aside from the annoying pop-up, I can still run projects.

Hi all,

got the same problems:

here what i did:

1. running jdk 6.17 and jre 6.23
-> no Error in Jabaco running the prog
-> Error when running compiled exe-file.

2. running jdk 6.21 and jre 6.23
-> no Error in Jabaco running the prog
-> Error when running compiled exe-file.


3. running jdk 6.23 and jre 6.23
-> Error in Jabaco running the prog
-> Error when running compiled exe-file.

Pressing 'Continue' program continues normally.

Looks like it really deals with the Java Version.
It seems as there's no workaround.

On my notebook I've got no problems running
Jabaco with jdk 6.21 and jre 6.22
