Restarting of tomcat server while using jsp

Hi,

Iam getting error at this particular point in the code

DirContext ctx = new InitialDirContext(env);

The function contains the following code

Hashtable env = new Hashtable();

env.put(Context.INITIAL_CONTEXT_FACTORY,

"com.sun.jndi.ldap.LdapCtxFactory");

env.put(Context.PROVIDER_URL,

"ldap://" + ldapServer + ":" + String.valueOf(ldapPort) + "/" + rootDn);

env.put(Context.SECURITY_AUTHENTICATION, "simple");

env.put(Context.SECURITY_PRINCIPAL, ldapUserId);

env.put(Context.SECURITY_CREDENTIALS, ldapPassword);

DirContext ctx = new InitialDirContext(env);

//at this point its gives array out of bound , java.util.vector error

Attributes matchAttrs = new BasicAttributes(ignoreCase);

if (matchRules != null) {

Iterator attrIter = matchRules.keySet().iterator();

while (attrIter.hasNext()) {

String key = (String) attrIter.next();

String value = (String) matchRules.get(key);

matchAttrs.put(new BasicAttribute(key, value));

}

}

response = ctx.search(searchBase, matchAttrs, returnAttrs);

lastResult = new Vector();

while (response.hasMore()) {

HashMap attrMap = new HashMap();

SearchResult sr = (SearchResult) response.next();

Attributes attrs = sr.getAttributes();

NamingEnumeration attrsEnum = attrs.getAll();

while (attrsEnum.hasMore()) {

Vector values = new Vector();

Attribute attr = (Attribute) attrsEnum.next();

for (int i = 0; i < attr.size(); i++) {

values.add(attr.get(i));

}

attrMap.put(attr.getID(), values);

}

lastResult.add(attrMap);

First time when i run it runs fine, but the second time , it gives error.
