Custom jars in MWS

[Keneilwe_Mafatshe1 (Keneilwe Mafatshe)]

Hi,

I am trying to attach a document to a task from CouchDb. I am using LightCouch to communicate with the database. I have added the LightCouch jar file on my project’s build path on designer as well as on MWS under the folder Software AG_directory/MWS/lib and subsequently restarted the server. I however get a java.lang.ClassNotFoundException when I run the project. The server seems to not pick up the jar file. The error logs are as follows:

We are using version 9.12

Hi Keneilwe,

custom jars for MWS should be placed under MWS/lib/ext instead of MWS/lib.

Regards,
Holger

[Keneilwe_Mafatshe1 (Keneilwe Mafatshe)]

Thanks for your response.

I moved my jar file to MWS/lib/ext as advised and I restarted the server. I continue to get the same error.

The 9-12 server administration guide has that custom jars should be added to the location Software AG_directory/MWS/lib. I have attached a screenshot.

Regards,
Keneilwe

Have you don’t the extra step of running the command that updates the OSGi profile as described in the “Adding Custom JAR Files” section of the MWS admin guide?

MWS runs inside of an OSGi runtime, so you must do extra work to convert plain jar files (that are not already OSGi bundles) into OSGi bundles and provision those OSGi bundles to the OSGi profile to make them available. The “Software AG_directory
/MWS/bin/mws.[bat | sh] update” command does that work for you after you have copied new jar files to the MWS/lib folder.

Alternatively, MWS 9.12 also supports autodeploy of jar files by copying them to the MWS\server\default\deploy folder, so that may be more convenient than those other steps and wouldn’t require a restart of the server.

[Keneilwe_Mafatshe1 (Keneilwe Mafatshe)]

Thanks Eric, I copied the jar into the deploy folder as you advised and it worked.

Keneilwe
