ORA-00911 exception is very common and usually occurs for common syntax mistakes. ORA-00911 occurs usually when a programmer makes one of the following mistakes

1. when a special character is added in an SQL statement with column name

2. when some non-printable/special character added because of paste of sql statement from other editer (usually Acute` instead of quote’)

3. when string is not enclosed by single quotes in where clause condition

4. when a extra semicolon (;) is added to end the query

5. when semicolon (;) is added to end the query in execute immediate of pl/sql

6. when semicolon (;) is added to end the query executing from programming language like .net or java

How to solve this problem? Or is there any other weblogic jar files needs to be used?

Set the ORACLE_HOME argument when executing the Java command at the command-line: i.e.:

The issue is solved. I changed the JDK location to C driver "C:" from "C:program files".

Apparently the following error is important:

The problem is the space in the middle of "Program Files". Do to the limitations on the name you can’t even use the 8-character abbreviated name for Program Files (usually PROGRA

1 ). I suggest you install WebLogic directly into the root of your C: drive, so try using C:weblogic .
