Hi
Iam getting problem java.lang.ClassFormatError: since 4 days Iam working on
but not finding a solution.
I tried with tomcat 4.0.3 and 4.0.4 beta version both gives same problem.
Installation is successful, and examples work properly.
I deployed my application in web-inf/classes
Iam getting an error when I run servlet.
When my servlet is invoked,
when code is trying to access the RelConnection.gDefaultConnectionIsOracle,
a static member Iam getting the error.
java.lang.ClassFormatError: com/CellFusion/Relational/RelConnection
(Illegal
Variable name "")
Relconnection is a public class with all static members and static methods.
In the same package it is able to get other methods. when it is trying to
access static variable iam getting this error.
Here is the description
---------------------------
I have written a servlet which SingleThreadModel
public class Login extends HttpServlet implements SingleThreadModel
In this one Iam trying to access oracle database using custom developed
classes
/**
* defineCFDatabase creates the Data Dictionary for 'cf'
**/
public static synchronized boolean defineCFDatabase()
{
try{
if (!gDBInitialized) {
gDBInitialized = dbCFDefinition.defineCFDatabase( false );
if (gDBInitialized) {
gDB = dbCFDefinition.getDatabase();
dboCF = gDB;
}
}
if (gDBInitialized && !gVariablesInitialized) {
gVariablesInitialized = initializeVariables();
}
} catch(Exception e) {
Util.log("********* Exception :" + e.toString());
}
return gDBInitialized && gVariablesInitialized;
}
In dbCFDefinition class
public static synchronized boolean defineCFDatabase( boolean forceAllTables
){
Access a class called DscDomain trying to get defaultId;
return boolean
}
DscDomain class calls a method as follows
public String getGenericType(String dataType , int length) {
if(!RelConnection.gDefaultConnectionIsOracle && mSQLServer){
//now only for SQLServer
if (dataType.toLowerCase().equals("varchar2")){
dataType = "varchar";
}
else if (dataType.toLowerCase().equals("number")){
dataType = "numeric";
}
else if (dataType.toLowerCase().equals("date")){
dataType = "datetime";
}
else{
dataType = "varchar";
length = 0;
}
}
if ( length == 0) {
Util.log("------- 2 if dataType" + dataType + "
length: " + length);
return dataType;
}
else {
Util.log("------- else dataType" + dataType + " length:
" + length);
return dataType + "(" + length + ")" ;
}
}
when RelConnection.gDefaultConnectionIsOracle is accessed Iam getting
problem
java.lang.ClassFormatError: com/CellFusion/Relational/RelConnection
(Illegal Variable name "")
RelConnection is a public class with static members and static methods
In the same package it is able to get other methods. when it is trying to
access static variable iam getting this error.
gDefaultConnectionIsOracle is defined as
static public boolean gDefaultConnectionIsOracle = false;
Thanks a lot

Post your code/log output. Maybe someone will have a look at it. Or you
could check the archives. I think I saw someone who had a similar problem.

Thanks for replying
I have synchronized methods and they are returning boolean. Can u please
let me know how that is getting affected and what I need to do to solve
that
problem. The class has static members and static methods, when iam trying
to
access static members the error is coming.
java.lang.ClassFormatError: com/CellFusion/Relational/RelConnection

Thanks a lot

Do you have any synchronized method? Are there any return statements within
the synchronized methods?
