Hi all,
<b>500 Internal Server Error
Application error occurred during request processing
Details: com.sap.engine.services.webservices.wsnavigator.WSNavigatorException: null
Exception id: [0016355ABDF800580000016F00002C7800043D23C1985713]</b>
I get the above exception when I run my webservice. I dont find any clue to debug my code, becuase i see little/nothing information thrown by the SAP j2ee engine. I dont get any exceptions while i compile, but i get this error when i am executing.
i have two classes, which I use as datastructure to return values from my websevice. Well, i will give you a psuedo code to make you understand better of what i have right now.
Class klass_1
{
public String var1="";
public String var2="";
...
public ArrayList arrList = new ArrayList();
// setter and getter methods for the above class members.
}
Class klass_2
{
public String var1="";
public String var2="";
...
// setter and getter methods for the above class members.
}
// following is a method in EJB, with that i have created a webservice
public kclass1 method_name(String arg1) throws SQLException{
// PreparedStatement to query database table
// Execute query and get result set values
try{
//instantiate klass1 and set its member with resulted values from above query
klass1 k1 = new klass();
k1.setMember_k1(result.getString(1));
// Query database with second query statement
// loop through result set you get from the above query
while(result_set.next()){
//instantiate klass2, initialiaze its members with resulted values from the second query, and add object of klass2 to 'arrList' of klass1
klass2 k2 = new klass2();
k2.setMember_k2(result.getString(1));
...
<b>k1.arrList.add(k2); // This line is giving me problem.</b> }
}catch (SQLException e){
...
}catch (Exception e){
...
}finally{
// close PreparedStatements, ResultSets, and connection obj to db.
return k1;
}
}
i know error-code: 500 occurs when there is problem with source. But the source compiles successfully. And also if i comment <b>k1.arrList.add(k2);</b> this line in the above code i execute the webservice with no problem but i dont get completely what i should get.
Can somebody help on this?
thank you,
sudhir.
