The error:
java.lang.ClassNotFoundException: testprocedure.tp$3 at java.net.URLClassLoader$1.run(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Unknown Source) at java.io.ObjectInputStream.resolveClass(Unknown Source) at java.io.ObjectInputStream.readNonProxyDesc(Unknown Source) at java.io.ObjectInputStream.readClassDesc(Unknown Source) at java.io.ObjectInputStream.readOrdinaryObject(Unknown Source) at java.io.ObjectInputStream.readObject0(Unknown Source) at java.io.ObjectInputStream.defaultReadFields(Unknown Source) at java.io.ObjectInputStream.readSerialData(Unknown Source) at java.io.ObjectInputStream.readOrdinaryObject(Unknown Source) at java.io.ObjectInputStream.readObject0(Unknown Source) at java.io.ObjectInputStream.readObject(Unknown Source) at core.ProcedureSetup.load(ProcedureSetup.java:57) at core.Engine.main(Engine.java:25)
I instantiate the object and call the "ProcedureSetup"'s "save" method from Class "tp".
ProcedureSetup ps=new ProcedureSetup(new Procedure(){ public void doStuff(){ System.out.println("Stuff is being done"); }});
ps.save();
however I load from a different collection of programs that has -ALL- required code but "tp"
ProcedureSetup ps=new ProcedureSetup();
ps.load();
Object saving and loading within class:
public void load(){
String path=Operator.persistentGetFile();//gets the file path
ObjectInputStream ois=null;
FileInputStream fin=null;
ProcedureSetup temp=null;
try {
fin = new FileInputStream(path);
ois = new ObjectInputStream(fin);
temp=(ProcedureSetup) ois.readObject();
ois.close();
fin.close();
} catch (IOException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
if(ois!=null){
try {
ois.close();
} catch (IOException e) {}
}
if(fin!=null){
try {
fin.close();
} catch (IOException e) {}
}
if(temp!=null){
a=temp.a;
}else{
load();//If a load is failed, restart process.
}
}
public void save(){
String path=Operator.persistentGetDirectory();//get directory to save to
String input = JOptionPane.showInputDialog(this, "Enter the File name:");
ObjectOutputStream oos=null;
FileOutputStream fon=null;
try {
fon = new FileOutputStream(path+input+".obj");
oos = new ObjectOutputStream(fon);
try {
oos.writeObject(this);
} catch (CloneNotSupportedException e) {
e.printStackTrace();
}
oos.close();
fon.close();
} catch (IOException e) {
e.printStackTrace();
}
if(oos!=null){
try {
oos.close();
} catch (IOException e) {}
}
if(fon!=null){
try {
fon.close();
} catch (IOException e) {}
}
}
My questions are:
Why are these errors happening?
Why (if necessary) do I need to have "tp" in my classpath?
If there is in fact a way to save the object in its current state with out the necessity of "tp" in the classpath how would I go about doing that? (Links would be lovely)
