Error can't load Servlet org.apache.struts.action.ActionServlet

[Former Member]

Hi,

I have SAP J2EE 6.20 installed on linux machine. I am trying to deploy struts framework based application and while deploying it..... I am getting error message:

Error can't load Servlet org.apache.struts.action.ActionServlet : java.lang.NoClassDefFoundError: org/xml/sax/SAXException

First time when I got this error, I added struts.jar in my server's <inst_dir>/alone/additional_libs/...... but then also error still exists... Do I have to start SAP J2EE instance once again and then deploy my application?

Can anyone help me out in this as this is very very very imp.

Wow, 6.20... Let me see if I can remember how it was done there...

You have to add the following line to the file <inst-dir>/alone/managers/reference.txt:

reference <your-app-name> library:inqmyxml

HTH!

hi....

thanks for the quick response. I added the following lines in reference.txt file.

reference <app_name> library:inqmyxml

reference <app_name> library:sapjco

reference <app_name> library:jdbc

reference <app_name> library:oracle_jdbc

reference <app_name> library:APIL_LDAP

and redeployed the application using SAPJ2EE 6.20 deployer tool. but still I am getting the same error.

Please please please please help me out on the same.

Hi,

As per your actions above I believe you have already found SAP Note 435363.

Basically for a struts application there are no special requirements other than

1. Make a reference to the inqmyxmltoolkit from the application that is going to use struts before the deployment

2. Put the struts library into WEB-INF/lib of the application (struts can't be shared among applications)

3. Deploy the application

For making the reference you can:

1. Telnet to the Engine (if you run it as a service and do not have access to its shell directly)

If telnet port on the Engine dispatcher is 2323

telnet localhost 2323

2. Jump to the server node

for example if the application node's cluster id is 4001

jump 4001

3. Execute the commands

add deploy
changeref -m  MyApplication library:inqmyxml

So if it does not work, then I see two reasons possible:

1. You are using a really old version of the 6.20 Engine - check if you are on PL41.

2. You have misspelled the name of your application in the reference. The names are case sensitive so you need to be careful. MyApplication is not the same as myApplication or myapplication.
