It's telling you *precisely* what the error is:

 org.xml.sax.SAXParseException: The content of element type "forward" must match "(icon?,display-name?,description?,set-property*)".

Hi,

But the same xmls are working in another enviroment but not in mine. The Ears are the same. I am really sceptacle abt teh jars, thats why i have given the jars . Please help.

Regards,
Acharya

[Sagar Rohankar]

struts-config.xml is not valid. Validate it against the DTD.

[Acharya Thiyagarajan]

hi all,

thankx for your response.. well there are many sturts configs each corresponding to a module and there are many tags how can i validate each of them ?? i have eclipse galileo I am ready to install anything to solve this issue?

Please help

Regards,
Acharya

[Acharya Thiyagarajan]

I have validated the dtds below is the entr in all the struts configs .. what can be the issue? this is also in the earlier code base

<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN"
"http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">

[vishwa venkat]

Verify what version of struts you are using 1.1. or 1.2 or 1.3.

Unzip/Unjar struts.jar and check the MANIFEST.MF in META-INF.

and make sure you have correct DTD specifier in your struts.xml

You do not have to validate each tag, you have to validate each config file.

Look at this link for tutorial explaining XML validation in Eclipse

Many congratulatiosn and thankx for all your help.. I indeed used your solution to check the same and the problem is solved there was a forward entry in the struts config which was not there in corresponding action and hence the application didnt even deploy.

From when did weblogic start doing such strict type checking? how can we disable it? Fresh install of weblogic 9.2 MP3 the check is enabled by default. once again thanks to all and in particular Sagar Rohankar from our whole team

Acharya

You can't disable it and every Java application server checks your xml for well formed ness and valid form before deploying them.

Others input too are correct, I just differ in explaining it more.. and welcome

As a quick update, I was dealing with a nearly identical issue just today. As was previously stated, the error (if you take the time to read it), does specifically describe precisely where the error was occuring. In my case, it was because several of my action-mapping's had a stray quotation mark at the end of each forward entry. Once removed, the struts-config parsed correctly and my server started successfully.
