When I started my computer at work in the morning, I found a problem with the application startup. The prompt was: Java. Lang. noclassdeffounderror: javax/transaction/transactionmanager. So I googled it and it turned out to be missing JTA. jar. It's strange that it was good. Why is it missing today? Is there a problem with eclipse.

 

JTA. jar:

1, http://java.sun.com/products/jta/ download class files, and then package into a jar file, or directly modify the suffix zip to jar

2, csdn download http://download.csdn.net/source/337356

 

The error message is as follows:
