Hi,

We got error [java.lang.NoClassDefFoundError]  when we moved from jBoss 5 to jBoss 6.

We are using version 1.4.0 of com.aspose.metafiles

ERROR [STDERR] net.sf.saxon.trans.XPathException: Exception in extension function java.lang.NoClassDefFoundError: com/aspose/metafiles/ob
fuscated/aP (wrong name: com/aspose/metafiles/obfuscated/ap)

More Stack trace is in attachment in error.txt

The problems seems to be with classloader  in jBoss 6 .

Thanks

Hi,

there is our code

licenseFile = loader.getResourceAsStream("Aspose.Metafiles.lic");
            if (licenseFile == null) {
                System.out.println("licenseFile not found");
            }
            // Instantiate the License class
            final License license = new License();
            // Set the license through the stream object
            license.setLicense(licenseFile);

            Metafile efile = null;
            if (fileExtension.equalsIgnoreCase("wmf")) {
                efile = new WmfMetafile(imageSourcePath);
            } else if (fileExtension.equalsIgnoreCase("emf")) {
                efile = new EmfMetafile(imageSourcePath);
            }

The error happened when is creating new instance of WmfMetafile
efile = new WmfMetafile(imageSourcePath);

HI,

It's been one week , without any response. Could we ask for progress on this issue ?

We tried the new version 1.7.0 with  eval . licence  and we got same error .

The problem comes from the obfuscation you use. Since you seem unable to resolve the problem, we'd like to request that you send us a special build with tweaks to the obfuscation: either don't use different cases (aw and aW, just standardize to all lower) or don't obfuscate the file names of the class files. I believe this would solve our problem while leaving your IP protections in place.

Hi,

Sorry for the delay. I am still working over this query and trying to build the test environment over my end. There have been some technical difficulties while building the testing environment but I think I can get them fixed shortly. Please spare us little time and soon you will be updated with the status of correction. We are really sorry for the delay and inconvenience.

Hello Lukas,

Thanks for your patience and sorry for replying you late.

I have tried reproducing this problem at my end but I am afraid I am unable to notice any issue. May be I am missing something while generating simple application using Aspose.Pdf for Java. Can you please share some sample .JSP so that we can test the scenario using it. We are really sorry for this delay and inconvenience.

This is not acceptable. I don't know why you're asking about JSPs; the problem is specific to ClassLoading the library in JBoss 6. Have you tried running a simple test within JBoss6? I suspect not.

It has now been almost 1 month since we first contacted support. We are a paying customer and this issue is preventing production code from working correctly. I have even recommended some possible solutions: 1. give us an un-obfuscated build of the jar, or 2. turn off class name obfuscation, but leave in place class body obfuscation.

If you are unable to resolve the problem, I would like to raise this issue to your manager. Since your company has no phone support, I will then try contacting management through your Sales numbers.

Hello Lukas,

Please accept our humble apologies for this delay and inconvenience. In fact in earlier attempts, I tried loading the class library into JBoss application, but I am afraid I could not test the scenario properly. Let me try involving the development team into this thread and I hope they would be in more appropriate position to mitigate this issue.

Once again I am really sorry for the inconvenience that you have been facing. We try our level best to help our customers in every possible scenario ASAP, but I am afraid this issue has taken longer time than normal.

Hello Lukas,

Thanks for sharing the license files.

I have tested the scenario and I am able to notice the same com.aspose.metafiles.AsposeLicenseException. More along I have observed that this exception is being generated if you try to access the application right after you have deployed it.

I would suggest you to please wait for some moments (may be around 20 to 30 sec) after deploying the application to JBoss and then try running the application. The license will work properly.

In case the problem is still not resolved, please feel free to contact. We are sorry for your inconvenience.
