Hi @eduilid,

please compare the war/WEB-INF/lib directories before and after.
If you have some ant-lib-copy-task to copy only the jars you depend on from your smartgwt/lib to yourproj/war/WEB-INF/lib, you might want to to check the filenames you are using.
There were many versions bumped between the releases. A missing jar might be the reason for Tomcat not starting up.

Best regard

Hi Blama,

thanks for your answer.

I compared file for file the libs and I see the following differences:

-commons-cli-1.3.1.jar -> commons-cli-1.4.jar
-new file appeared in new version: commons-collections4-4.1.jar
-commons-fileupload-1.3.1.jar -> commons-fileupload-1.3.3.jar
-commons-io-2.4.jar -> commons-io-2.5.jar
-httpclient-4.5.2.jar -> httpclient-4.5.3.jar
-httpcore-4.4.4.jar -> httpcore-4.4.6.jar
-isc-jakarta-oro-6.0-020161005.jar this file disappeared in the new version
-the following files changed from version 6.0-p20161005 to 6.1-p20171105:
isomorphic-assembly
isomorphic-compression
isomorphic-content-export
isomorphic-core-rpc
isomorphic-js-parser
isomorphic-messaging
isomorphic-sql
smartgwt-messaging
smartgwt-power

all other files are the same. Everything seems to be correct. I attach the complete list of jar files in the new version. Maybe there is some library conflict? But this did not happen with the old version.
Thanks.

Hi,

if you have the same libs before and after in your Tomcat app/WEB-INF/lib directory (this is how I understand your post, some 3rd party libs versions bumped, some SmartGWT libs new without file name change, commons-collections4-4.1.jar new), I don't understand the issue you are seeing, either.

Generally speaking:
Are all the files you list in the end in that directory? If so, having e.g. stax-api-1.0-1.jar and stax-api-1.0-2.jar both in the folder can definitely cause problems - both files will define the same classes. How should the JVM decide which to use on a new ...? Same for bcmail-jdk14-1.38.jar and bcmail-jdk14-138.jar without the dot.
It is always a good idea to keep the list of libs as short as possible in order to safe space and deployment time, but also to prevent the "JAR hell". For SmartGWT, here is the list of mandatory JARs depending on the features you use.

Best regards
Blama

Actually....see this line in the logs:

Code:

Caused by: java.lang.IllegalArgumentException: java.util.zip.ZipException: invalid LOC header (bad signature)

Perhaps some JAR is broken? Can you open all the jars in e.g. WinRAR (a JAR is just a renamed ZIP file).

Best regards
Blama

**edulid** · 8 Nov 2017, 01:39

Hi Blama,

you are right, yes, I will clean the files / file versions. But, since exactly these jars were in use in the previous version and are working, this should not cause any problems with the new version, or am I missing something ?

**edulid** · 8 Nov 2017, 01:52

I successfully opened all .jars manually with winrar. So they seem not to be corrupt.

**edulid** · 8 Nov 2017, 02:36

After investigating by replacing the jars one by one from the old version to the new version , I found out that as soon as I replace this jar: httpclient-4.5.2.jar with httpclient-4.5.3.jar the problem happened.
So I downloaded this file again (manually), then manually replaced it, and everything works. I don't really understand it, I am able to open the file with winrar, so it seems not to be corrupt.

I will delete the file from my m2 repository and will try again with maven.

**edulid** · 8 Nov 2017, 02:48

Ok, after letting maven download the file again the problem is gone ... I am not sure how this can happen.. maven to download a corrupt file and this file to be able to be opened with winrar...

Glad you got it working.
Only thing I can think of is that opening is not extracting. Perhaps WinRar would have had a problem when you tried to extract the file.

Best regards

This is correct, when trying to extract the files winrar complains... but with the new file everything is fine :-)

Thanks!
