Error thrown when using aspose.word.jasperreports and aspose-words at the same time


I am now implement the java program with two functions:

  • using aspose.word.jasperreports-6.3.0-6.4.0.jar to convert the jasper file to word document.
  • using aspose.word-18.9-jdk16.jar to read the docx template to generate word document.
    The program work fine when only include 1 library (either jasper one or word). But when include two libraries at the same time. One of the function will throw error like this:

For aspose word generate:
Exception in thread “main” java.lang.VerifyError: Bad type on operand stack
Exception Details:

For aspose.word.jasperreport generation:

I am using jasper report server 6.3.0.

Please let me know if there is any conflict to this two library and how to solve it. Thanks.

Thanks for sharing the detail. We have tested the scenario using “” and faced java.lang.NoSuchFieldError exception. We have not faced the same exception that you shared. For the sake of correction, we have logged this problem in our issue tracking system as WORDSJR-242. You will be notified via this forum thread once this issue is resolved. We apologize for your inconvenience.

We have not found any issue while using Aspose.Words for Java 18.9.

It depends on which library class is loaded. If the aspose word is loaded, the aspose word can generate word document well and jasper to word will malfunction and vice versa.

Hope that this can help your investigation. Thanks.

Is there any schedule for fixing this issue since we are planning to buy the product once the problem is solved?
