Here is My code but it's giving an exception.
net.lingala.zip4j.exception.ZipException: cannot delete old zip file

public boolean removeFileFromZipFile(String zipFilepath, String filepath) {
try {
ZipFile zipFile = new ZipFile(zipFilepath);
zipFile.removeFile(filepath);
} catch (ZipException ex) {
ex.printStackTrace();
return false;
}
return true;
}
this code is working if I'm calling single method Like
removeFileFromZipFile("E:\POC\files\test.zip", "test.html")
it's not working when I'm trying to do below operation like in sequence.
getFileFromZip("E:\POC\files\test.zip", "test.html") removeFileFromZipFile("E:\POC\files\test.zip", "test.html") // here i'm geting exception
public String getFileFromZip(String zipPath, String filePath) {
String data = null;
ZipInputStream is = null;
try {
// Initiate the ZipFile
ZipFile zipFile = new ZipFile(zipPath);
if (zipFile.isEncrypted()) {
zipFile.setPassword("abc@123");
}
FileHeader fileHeader = zipFile.getFileHeader(filePath);
if (fileHeader != null) {
is = zipFile.getInputStream(fileHeader);
data = IOUtils.toString(is, StandardCharsets.UTF_8);
System.out.println("Data :: " + data);
} else {
System.err.println("FileHeader does not exist");
}
} catch (Exception e) {
e.printStackTrace();
}
return data;
}
Make sure you close the file after creating it, and reopen it before attempting to delete a member. Otherwise the file remains locked and cannot be deleted and recreated during the member delete operation.
