Using multiple parsers in classpath.

What a mess? Many things are wrong here. Don't know what is for what.

• Most of the jars listed here are not parsers.
• "I have following parsers ( they are needed by dff applications, so cant get rid of any of them ) in my classpath." Wrong! You should set different classpaths for different applications. Not set all of them in the same environment variable.
• Many class libraries you listed here are not binary compatible, put them all on your classpath is definitely disaster prone.
• What you or your project team really need is a good architect.
• I think I can help to straight things out. However, that cannot be solved by a post. That should be at least a paid online tutoring session, provided you and/or your company are interested.
