    • buildComponentClassPath

      public String buildComponentClassPath() throws IOException
      Creates a string that should be added to the CLASSPATH to run the given installed component, based on its installation descriptor specifications, as well as the contents of its lib directory. The output string includes absolute path expressions for all relevant objects containing in the component PEAR package. If the component package is archived, returns null.
      Returns:
      The string that needs to be added to the CLASSPATH to run the given installed component.
      Throws:
      IOException - If any I/O exception occurred.
    • buildComponentRuntimeClassPath

      public String buildComponentRuntimeClassPath() throws IOException
      Like buildComponentClassPath(), but without all jars from the lib dir.
      Returns:
      The runtime classpath for the component.
      Throws:
      IOException - if there was an IO problem
    • buildComponentClassPath

      public String buildComponentClassPath(boolean relativePath, boolean addLibDir) throws IOException
      Creates a string that should be added to the CLASSPATH to run the given installed component, based on its installation descriptor specifications, as well as the contents of its lib directory. The output string includes absolute or relative path expressions for all relevant objects containing in the component PEAR package, depending on the value of a given boolean argument. If the component package is archived, returns null.
      Parameters:
      relativePath - If true, the output string will include relative path expressions for all relevant objects containing in the component PEAR package, otherwise it will contain absolute path expressions for these objects.
      addLibDir - Whether to add jars from the lib dir to the classpath (true at packaging time, false at runtime).
      Returns:
      The string that should be added to the CLASSPATH to run the given installed component.
      Throws:
      IOException - If any I/O exception occurred.
    • buildComponentPath

      public String buildComponentPath() throws IOException
      Creates a string that should be added to the PATH to run the given installed component, based on the PEAR package defaults and its installation descriptor specifications. The output string includes absolute path expressions for all relevant objects containing in the component PEAR package. If the component package is archived, returns null.
      Returns:
      The string that needs to be added to the PATH to run the given installed component.
      Throws:
      IOException - If any I/O exception occurred.
    • buildComponentPath
