如何处理java.io.IOException：表单数据损坏：com.oreilly.servlet.multipart.MultipartParser中提前结束？

Question

Environment : - Jboss EAP 6.3 Alpha 1

JDK : - JDK 1.7 u_80 64 bit

We have a program functionality which is absolutely working fine in JDK 1.6 u_32 64 bit. Once we upgraded it to JDK 1.7 u_80 64 bit, it started throwing exception message "Corrupt form data: premature ending" . Following file is using in program http://central.maven.org/maven2/com/servlets/cos/05Nov2002/cos-05Nov2002.jar

It is quiet critical to find cause and solution of the problem because problem is varying in JDK 1.6 u_32 64 bit and JDK 1.7 u_80 64 bit. But from the trace, it seems that problem clearly belongs to com.oreilly.servlet.multipart.MultipartParser.(MultipartParser.java:205)

On printing stack trace, we found following exception: -

java.io.IOException: Corrupt form data: premature ending

Answer 1

MultipartRequest multi = new MultipartRequest(request, "C:\\Users\\HP\\workspace\\Project_OnlineExa\\WebContent"); 

应该是Servlet的第一行
